Is content king?

Originally posted on August 14, 2016 @ 9:00 am

This post was written in 2016 and does not reflect my current thinking about teaching biology. Please see this post to read about my updated views on teaching the subject.

I have reached a watershed in my thinking about teaching and my philosophy about teaching science.

I trained and begun learning to teach in a school with a very robust academic record. Teachers were considered absolute experts in their field and students were, on the whole, very high achieving but who had high expectations of their teachers academically too.

In this environment I learned that the teacher’s fundamental responsibility was to be an an absolute expert in their field; if you didn’t know everything, and could not answer every question, the community of students would lose faith in you. Or at least that it is what it felt like.

I mentioned in my review of Ritchhart et al of comments made by an ex-colleague of mine which reinforced this sentiment.

In those formative days then learning to teach was about mastering your subject knowledge. Content was King. Delivered in lovely little powerpoint slides where students would simply copy down their notes and then memorise them.

I left that school confidently arrogant that I was an expert in my subject and in the IB. That any school was going to want to employ me after the time that I had spent in that school. And indeed I was partly right. I secured a position as Head of Biology at a prestigious boarding school. The time there was little different. I benefitted from working closely with the chemists and physicists, in a closely knit science department. However the sentiments were the same. Content was King. Our role as science teachers was to deliver the curriculums content. The learner profile was dismissed by the Head of Science as fluff.

Since moving on from that school I have been involved in setting up a school and taking it through its IB authorization process as the only Biology teacher and as one of two or, more recently, three science teachers. I cannot point to any single experience from this time that has been the catalyst but my thinking has begun to change. Perhaps it was being forced to seriously consider the IB’s other bits; the ATLs; the IB Learner profile. Perhaps it was being exposed to and challenged by the MYP. Perhaps it was teaching a new DP Biology syllabus with so much focus on the nature of science. Perhaps it was beginning to teach TOK. Perhaps it was becoming a workshop leader. Perhaps it was working with so many truly excellent IB educators. I don’t know.

But I now question the sentiment that content is king in science teaching.

I am beginning to think, to really think that more important than learning the content, my students need to learn to think. It might sound like an odd thing to write. It certainly feels like an odd thing to write.

I’m sure that many people who aren’t teachers would raise their eyebrows at what I wrote above. Surely, a teachers job is to teach students to think? But it’s not as simple as that. Teaching students to ask strong questions and to develop different thinking dispositions is no simple task. It’s much easier to focus on the curriculum delivery. What are my students supposed to know? Fill the time in with student-centred activities, and group work, debates and presentations and you are doing a good job right?

I’ve moved on from didactic lecture like teaching in my early days to worksheet, activity based teaching but has anything really changed? My students still present as apathetic. School is still something that they just do on the whole. I’m sure most of them forget what they “learn” instead of engaging with the deeper issues.

And this is what I want: I want my students to be engaged, passionate and switched on critically to the world around them and be scientifically literate.

How do I do that when sometimes I question my own scientific literacy?

Perhaps its time to really focus on the thinking and the types of thinking that are needed in science and needed to be developed in students of science. The trouble is I am sometimes not sure that I know what thinking really means…

In Making Thinking Visible Richhart et al (2011) discuss turning the content into a vehicle for teaching and framing certain thinking skills. It is argued that developing thinking skills is important because these skills are the tools that students will take forward into future life when the content is forgotten. They are the tools the future adults will utilize to navigate life.

The thing is, thinking doesn’t just happen. As teachers, we need to be explicit with students about the types of thinking that are useful in certain situations and provide strategies that help students learn to think in these ways. We can’t just leave it up to chance. After all, traditionally, we don’t leave the content up to chance (normally), instead, we are explicit with it. We need to give students the chance to think about their own thinking and what it means to them.

Ritchhart provides a list of “high-leverage thinking moves that serve understanding well”:

  1. Observing closely and describing what is there.
  2. Building explanations and interpretations.
  3. Reasoning with evidence.
  4. Making connections.
  5. Considering different viewpoints and perspectives.
  6. Capturing the heart and forming conclusions
  7. Wondering and asking questions
  8. Uncovering complexity and going below the surface of things

I will be posting these “moves” in my classroom as a start as well as try to relate the activities we are doing to these types of activities.

As science teachers, we need to ask ourselves: What type of thinking is important in science? More specifically what types of thinking do we want to develop in students of science? How is thinking framed in terms of the work that scientists do? What are the essential questions of science?

Clearly, the thinking moves above are addressed by different elements of scientific enquiry. Observing closely is an important part of observational studies and also hypothesis generations so is wondering and asking questions. To generate a hypothesis requires building explanations and reasoning with evidence. When we draw our data out we try to capture the heart of a problem and draw a conclusion,

Once we have a clear idea of this then we can begin to teach the thinking alongside an understanding of the nature of science through well-planned content. The difference is that our learning objective is twinned – we have a thinking objective and a content objective.

Understanding how to teach in this way is important.  Biology teacher Paul Strode has written some articles in this vein. In one he looks at reasoning like a scientist and the other deals with teaching the hypothesis. Although he still focuses on framing the content instead of necessarily framing the questioning, these are good reads. However, I feel that the questioning and thinking strategies needed to become front and centre of the teaching instead of the content.

Thinking relies heavily on questioning. In science we are trying to ask the following questions:

What do I notice?

What does that tell me?

Why does it work like this?

How can I test this idea?

How can I be sure that my findings are valid?

Or, according to strode whose list is below:

Step 1: What claim am I being asked to accept?

Step 2: What evidence supports the claim? Is the evidence valid?

Step 3: Is there another way to interpret the evidence?

Step 4: What other evidence would help me evaluate the alternatives?

Step 5: Is the claim the most reasonable one based on the evidence?

Teaching like this requires teachers to step down as the “font of knowledge” in their classrooms and have the courage to be wrong. I have worked in schools where the culture of the school would simply not allow that to happen.

As Ritchhart points out we need to be able to ask our students authentic questions, meaning that the teacher needs to not know the answer, and if teachers are worried about seemingly not knowing something how can they do this?

This academic year I am going to try and put thinking centre and front in my classroom. I just hope that the crazy timetabling and work-load pressure doesn’t push me back into easy, old habits.

Learning Theory & Educational Neuroscience

Originally posted on April 2, 2016 @ 4:23 pm

I wrote this article in February 2015 as part of my PGCE Top-Up course at the University of Northampton. This is a course aimed at teachers who already have completed initial teacher training through the graduate training programme and gained QTS, but want to add on the university PGCE to this qualification.

Why publish it here? I have found that my own interests within Biology have developed hugely since I started teaching, taking me to academic areas that I never studied in my original Zoology degree. This is partly through trying to keep abreast with a subject whose post-16 content has changed and continues to change dramatically year on year and also partly through my own genuine interest in the subject. The brain and behaviour has been one of these areas.

As teachers we have a natural interest in how the mind works and how individuals learn. In one (very loose) sense teachers are Biologists because of this interest; we want to understand the mind of this species of hominid and how it develops.

My interest in educational neuroscience represents for me a cross over of these spheres of interest in my own professional life – biological science, specifically neuroscience and education.

Thoughts gratefully received.

Introduction

On 19th October 1964 a paper was published in the journal Physical Review Letters. In it the author, Peter Higgs, hypothesised about the existence of a fundamental particle that was responsible for giving mass to other fundamental particles: the so-called Higgs Boson (Higgs, 1964). 47 years, 8 months and 15 days later, the European Organisation for Nuclear Research, CERN, confirmed that experimental physicists working at the facility had demonstrated the existence of the particle (CERN, 2015).

This story of discovery illustrates the wonderful interplay in science between scientific theory and scientific fact. The Higgs theory was just one of several competing models which had been proposed over 4 decades to explain how fundamental particles may interact. With the discovery of the Higgs Boson, the Higgs theory, with some modification, was proved to be the correct explanation.

In a similar way neuroscientific studies of the brain and its functioning could be used to constrain and validate psychological theories of learning. Educational practice uses psychological theories, developed over the past century or so, what if we attained physical evidence to illuminate which ones should be developed and which ones could be discarded?

Modern educational theory has diversified hugely with specialist areas devoted to studying different learning contexts e.g. classroom, outdoor, experiential, life-long, as well as at different developmental stages e.g. early years, school-age, university and adult (For a review see Illeris, 2009). It is only relatively recently that educational researchers have begun to try to forge links between education theory and neuroscience (Geake, 2009), while some have questioned the basic ability of these two fields to be bridged (Bruer, 1997).

I will review the evidence that educational neuroscience is yielding, and review the arguments for and against use of neuroscience in the context of education. Neuroscience still has much to learn about the brain but we already have an understanding that can inform educational practice on a variety of levels. I will begin by describing the development of psychological theories of learning before moving on to examine the contribution that modern neuroscientific or brain based theories of learning may yet make towards developing our understanding of how humans learn.

Learning Theory

Humankind’s interest in learning and teaching could be said to go right back to the early days of our pre-history when, as a new species, we had to invent new ways to respond to a changing environment. Indeed learning is without doubt a very, but not solely, human trait; it is essentially what has allowed us to adapt to every environment on the planet.

Modern attempts to explain how humans learn have their roots in the psychological theories of the late 19th Century with the advent of cognitive psychology, behavioural science and ethology (Pritchard, 2009).

In the 20th Century behaviourists, notably Skinner (1958), developing the work of Ivan Pavlov, focussed on innate behaviour in animals and discovered the mechanisms of conditioning and reinforcement. Behaviourist approaches to understanding learning and human development view learning as the acquisition of new behaviour (Prichard, 2009).

In contradiction to behaviourism, constructivism views learning as the result of mental construction i.e. new learning is added to pre-existing knowledge. Piaget (1954) and Vygotsky (1997) separately developed their own particular brands of constructivism which differed fundamentally about how learning is constructed: Piaget viewed learning as being cognitively constructed and that students acted as lone scientists who learn through discovery; Vygotsky viewed learning to be socially constructed, with the teacher (and other students) having a significant contribution to play in scaffolding the work and setting the challenge for their students (Pritchard, 2009).

The influence of these theories cannot be understated. Constructivism is the key idea in education, underpinning not only many modern theories of learning, but also curriculum models (like the International Baccalaureate, an inquiry-based curriculum model [IBO, 2015]) and classroom based pedagogical approaches. Today it is taken for granted that learning is constructed within the mind of the learner and therefore new learning builds upon prior learning and understanding. This is the overwhelming epistemological standpoint that underpins all of modern theories of learning (Samuels, 2009).

Neuroscience and Education

Much of the early research in neuroscience focused on the structure and function of neurons, the specialised cells that make up the brain and nervous system. These neurons, form connections (synapses) with each other. At these synapses individual neurons are able to generate or inhibit the “firing” of impulses within the other neurons that they are connected to. In this way neurons are assembled into neuronal groups or brain modules (Geake, 2009). It is these neuronal groups, their interconnectivity and how they may relate to pedagogical practice that is of interest in educational neuroscience.

An early neuroscientific model of learning, that is still robust today in terms of its explanatory power is that proposed by school-teacher turned neuroscientist Donald Hebb (1949). In Hebb’s model of learning it is the number of connections within the brain not the number of neurons that is important. He states that when a neuron stimulates or inhibits a signal in another neuron across a synapse, that synaptic connection is reinforced. Conversely when signals are not issued across a synapse very frequently, that junction between the two cells, is not preserved. Thus neurons that consistently communicate with each other have their synaptic connections maintained, while those that do not lose their connections.

Attempts to link the findings from neuroscientific research and formal educational practice date back to the 1980s (Bruer, 1997) and since that time, opinions of educational researchers have been divided on the usefulness of neuroscientific research in education (see Bruer, 1997, Geary 1998, Geake & Cooper, 2003, Goswami, 2004). However, recent writers are less pessimistic (Goswami, 2006, Varma et al., 2008, Samuels, 2009, Ansari et al., 2011, Howard-Jones et al., 2014,  Howard-Jones 2014, Schenk & Cruickshank, 2014) and the trend in published articles becomes more positive. Indeed, it is telling that in the last decade we have seen the formation of the International Mind, Brain and Education Society (IMBES) along with the Mind, Brain and Education Journal. The Societies aim is to “facilitate cross-cultural collaboration in biology, education and the cognitive and developmental sciences” (IMBES, 2015). In addition there have been two formal reviews of the field, first by the Organisation for Economic Co-Operation and Development (OECD, 2008) and the second by the Royal Society (Royal Society, 2011). All of these developments suggest that the findings from neuroscience and education research are beginning to converge.

Many of the arguments questioning the usefulness of educational neuroscience have focussed either on the limitations of the methodologies employed in studying neuroscience or the extrapolations that education professionals (researchers, teachers, civil servants) have made about the results from neuroscientific studies resulting in the so-called “neuromyths”.

Bruer (1997) argues that neuroscience only has an explanatory power when viewed through cognitive psychology. He described the three fields of classroom instruction, cognitive psychology and neuroscience as being spanned by two bridges – one from instruction to cognitive psychology and a second from cognitive psychology to neuroscience and that only by contributing to our understanding of cognitive psychology could neuroscience hope to deepen our understanding of classroom learning. He describes using neuroscience to study learning as a bridge too far. His essay has been citied a great number of times and the arguments he makes are worthwhile to the classroom practitioner.

Bruer’s premise is that studying the mind is not necessarily informed by studying the brain. This argument is rebutted by Cruickshank & Schenck (2014) and Howard-Jones (2014) who argue that because the mind is created by the brain it must have biological correlates. The systems of processing in the mind must be reflected by systems in the brain. This is an idea that as a Biologist and Science Teacher I tend to agree with.

Bruer (1997) also describes at length the early work of neuroscience that was conducted on single neurons in rats, mice or monkeys. He demonstrates that much of the evidence from these studies has been extrapolated to humans and used to describe human neural development. He makes the valid argument that extrapolation from rats to humans is a large assumption. This extrapolation has formed the basis of many “neuromyths” – misconceptions about learner’s brains that have been adopted by the education community. These misconceptions tend to contain “nuggets” of truth which have been misunderstood or poorly applied (Howard-Jones 2014).

Goswami (2006), Geake (2009) and Howard-Jones (2014) provide excellent up to date considerations of the neuromyths that have been adopted by the education community. They cite the ideas that learners are left or right brained; brains are male or female; the existence of brain buttons under the ribs; that there are critical periods for learning; that brains process information from different senses independently and that there are, consequently, individual learning preferences, as examples of neuromyths.

The prevalence of neuromyths cited within the literature and used to support various philosophies and policies of education is used by Bruer (1997) as evidence that neuroscience cannot, and should not, influence education. It seems to me that this argument is to misunderstand and misappropriate the role of science in society. It is precisely because neuromyths abound that systematic research needs to be conducted and communicated clearly to stakeholders. The reports from the Royal Society (2011) and the OECD (2008) along with Geake (2009) and many other authors now highlight the need for initial teacher training that provides some training in general scientific and neuroscience specific methods, as well as making an argument that deeper collaboration between the education and neuroscience academic communities is necessary so that educators and neuroscientists are able to better spot and counter these myths with biological evidence. Educational neuroscience has great potential to become a transdisciplinary area of collaboration with ideas from both fields influencing the other.

Bruer (1997) also writes about the problems with interpreting data from neuroimaging studies as well as the use of neuroimaging technology to study educational problems. In the 1990’s there was a huge expansion in development of technologies used to study the brain. For a review of these methodologies see Geake (2009) but it is important to note that the maps produced by scans of the brain are averages and do not necessarily represent individual brains. At that time neuroimaging technologies had very little ability to ask questions about classroom practice due to their size and cost, however these limitations are dramatically decreasing (Royal Society, 2011, OECD, 2008) and studies that actively image the brain during specific classroom based tasks are beginning to be published.

The relationship between neuroscience and the psychological study of literacy and the acquisition of language in school children is the oldest and most robust (OECD, 2008) and researchers in the field now have a good understanding of the neurological correlates for language learning which can inform the choice and timing of pedagogical activities. There is a sensitive but not critical timing for learning a second language in the early years of education (Geake, 2009 & Royal Society, 2011).

Educational neuroscientific research into the neurological correlates for numeracy and mathematical ability is newer, although important evidence is already emerging about how the brain processes the different mathematical information and learns specific mathematical skills (Geake, 2009 & Royal Society, 2011).

Perhaps the most interesting and important questions that educational neuroscience is addressing are those concerned with learning difficulties. Educational neuroscience research has now provided a biological basis for the causes of Dyslexia. Diagnosis of the condition can be made based on neurological evidence and when twined with an improved understanding of how the brain processes word forms and sounds, neurological evidence can suggest effective methods of treatment. Similar work on Dyscalclia is already underway (Geake, 2009 & Royal Society, 2011).

Several authors (OECD, 2008, Geake, 2009, Royal Society, 2011) provide a thorough overview of the key findings from neuroscience generally and how they may apply to educational practice. A key general understanding is that no two human brains are the same. This may seem trite but even identical twins, which are the same genetically, show differences in their brain structure. This illustrates how much the brain is shaped by the environment it interacts with. The Royal Society 2011 writes:

“The brain is constantly changing and everything we do changes our brain…the brain has extraordinary adaptability, sometimes referred to as ‘neuroplasticity’”

The report goes on to explain that this is due to the processes that strengthen synapses and the effect is present throughout life. Contrary to early ideas of brain development we now know that the brain can adapt, change and therefore learn throughout life even into old age (OECD, 2008). Throughout life new synapses grow and are pruned but this process of pruning and growth is most prevalent at certain sensitive periods, from early childhood to late teens and early twenties. Individual experiences and environments shape individual brains (Royal Society, 2011).

While Individuals show differences in the structure of their brains this does not mean that there is evidence for individual learning styles of preferences. Due to the massive interconnectivity within the brain between individual neurons and between brain modules we know that information is processed across a wide variety of areas of the brain and that these areas are overlapping and interlinked. The ideas of learning styles –that learners learn exclusively through one sensory modality are false (Kratzig & Arbuthnott 2006). For example the areas of the brain that process speech overlap with those that process movement. The idea that an individual processes visual information in isolation from any other sense is another example of a neuromyth (Geake, 2009). In fact the interconnectedness of different sensory areas within the brain supports the notion of multisensory teaching i.e. approaching subject matter and skills through a variety of sensory inputs as this will enable more robust networks of neurones to form in the same manner as may be expected from repetition.

Geake (2009) defines the purpose of education as enabling the individual to gain transferable life skills from a variety of contexts. He also points out that learning in the form of memory formation of skills and concepts requires directed attention from working memory i.e. the engagement of the prefrontal cortex and the areas associated with working memory. Evidence shows that learners need to be guided. The brain can just as easily learn incorrect skills and content, but unlearning them is difficult because it requires the pruning of connections in the brain. Thus there are implications for inquiry based teaching methods and the idea that gifted students are able to teach themselves. Adult guidance and encouragement along with appropriate intellectual challenges should therefore be a central strategy for schools (Geake, 2009, Krishner et al., 2006).

Geake (2009) highlights the need for repetition within the learning environment of an individual. Repetition over time reinforces synaptic connections and allows the effective transference into long term memory. He illustrates this argument with the example of learning music. Hours of practice of the correct finger movements on an instrument allow the motor cortex to develop the neural networks that control the movement sequences. He does not advocate repetition in the sense of drilling exercises but suggests that spiral curriculums where individuals meet related concepts throughout their school experience, each time at a deeper and deeper level, along with lower pupil rations and immediate feedback from assessment to correct errors in processing would be beneficial for learners.

Educational neuroscience has also highlighted the interdependence of intellectual and physical wellbeing and much work has highlighted the importance of emotional wellbeing for learning (OECD, 2008). We now know how stress can inhibit learning because the centres of the brain that deal with emotion affectively inhibit the areas that help to regulate activity across the brain and are used in learning.

Conclusion

Modern theories of learning build firmly upon constructivist ideas (Samuels, 2009), but precisely because there is such a plethora of modern learning theories means that they cannot all be right (Geake, 2009).

Gardner’s (1983 & 1999) theory of multiple intelligences, a retelling of Plato’s ideal curriculum, is one such educational theory that must be qualified. It has been widely cited in educational policies and led to many misinterpretations such as labelling all children in a school as gifted by definition Geake (2009). Howard-Jones (2014) and Waterhouse (2006) argue that there is no neural evidence to support the idea of multiple intelligences but that there is evidence to suggest that there is a general cognitive ability underpinning all the possible dimensions of intelligence.

While massive differences exist in brain structure, the interconnectivity of the brain does point to a single underlying intelligence factor. Intelligence does have a genetic and environmental component in the same way that an individual heights do. Genetically, intelligence is brought about through the interaction between many genes; each of which have an individually small effect. The environment also has a role to play in unlocking the brains potential as diet, toxins and social interactions all up-regulate or down-regulate the effects of genes. A good social educational environment will enable an individual brain to reach it full intelligence potential (Geake 2009). 

At this stage educational neuroscience may not have the resolution to inform specifically about many aspects of classroom pedagogy (e.g. in science teaching) or classroom contexts but it is able to inform us about generalities that may inform curriculum planning on a whole school and regional basis. E.g. sleep patterns and gender differences, developmental differences, as well as serving to identify the psychological theories that may be most robust.

Obviously if we were to remove an individual’s brain we would soon find that they had lost the ability to learn altogether! Therefore is it unreasonable to be able to expect the workings of the mind to be understood through a deeper understanding of the brain?

The beauty of educational neuroscience is in its potential ability to underpin and constrain psychological theories of learning. Like Higgs with his Boson and the experimental physicists that validated its existence, educators are on the cusp of not only being able to identify a psychological intervention that works but also able to explain why it works, thanks to the evidence derived from educational neuroscience. To enable this we need better communication between the education and neuroscience communities.

Practical & Teaching Resource: Genetic Databases

Originally posted on April 3, 2016 @ 9:10 am

Preamble

One of the challenges I have found for teaching the new (2016) IBDP Biology syllabus is getting up to speed with the new content as expressed in the understandings, applications and skills sections of the syllabus. This has been particularly true when this new “content” implies an understanding of new technologies such as the huge rise in bioinformatics databases. To make matters worse, I am the only biology teacher in my school and I have been acutely aware of this when, stumbling across new requirements, I have had no one to bounce ideas off (or steal resources from! :))

So what do you do when you have new content that you have not taught before, that relies on an understanding of bioinformatic technology that wasn’t widely available, or covered on your masters in ecology eight years ago and you have no colleagues to help you? You go back to the drawing board…

When planning my course the year before I had shunned ordering the text book written by the chief examiner for the subject for my students on the grounds that it was too big and heavy. I had opted for a slimmer, light-weight textbook that was written by an old colleague. However, In preparation for times like this, I had purchased a copy for my own reference, not to teach from the textbook, you understand, but to refer to when I was unsure of exactly how much depth a topic needed going into (and therefore how much classtime to devote to it) or what the chief examiner had in mind when he wrote the course as part of the curriculum review committee.

While I applaud the move away from a list of learning statements as we had in the old syllabus, statements from the understandings section, like this one from topic 3.1 Genes:

The entire base sequence of human genes was sequenced in the Human Genome Project”

often leave me wondering how much time needs to be allocated to them. This is where having a copy of the chief examiners textbook comes in handy.

The Practical

Earlier this term I was teaching the IB Biology core topic 3 – Genetics and while planning came across the following statements:

3.1 S1: “Use of a database to determine differences in the base sequence of a gene in two species

3.2 S1 “Use of databases to identify the locus of a human gene and its polypeptide product”

These along with several other “application” statements in 3.1 an 3.2 left me slightly bamboozled as to how to approach teaching this, seeing as I had never used these kinds of databases in this way myself, and whats more I was left asking the question – aren’t the kinds of databases that these statements refer to way too complicated to expect 16-18 students to be able access?

Anyway, the instruction was there so I had to do something with it. In the end I referred to the Allott & Mindorf (2014) textbook along and the inthinking biology teacher resource website and combined and adapted two of their practicals to use in my classroom. The result is below:

  1. I designed a practical protocol worksheet which is available here, which could be printed out and handed to students. There is QR code which, when scanned, links to the following video.

  1. I made the following video that takes students through the worksheet. They can be used together.

Reflections

The video and the activities together take about an hour or just over to complete and do count towards practical hours on the PSOW. I am hugely indebted to the work of Allott & Mindorff and David Faure at inthinking to be able to produce this. Students are able, if they have a mobile phone and QR scanner to link directly to the film and follow the instructions. Alternatively the video can be played on a projector. Students could also complete this as a homework task but this couldn’t then count as practical.

I think that the video and the activities could be broken up into smaller individual activities as I think this may help students to process exactly and clearly what they are doing. These databases can be complex to navigate and contain a lot of information which can be overwhelming for anybody who is new to this area.

While I personally like this part of the syllabus and think that there are some possible IA ideas here, especially when combined with evolutionary studies, I can’t help but think that this material is a bit too advanced for 16-19 year old students, particularly for SL students. It is fairly niche and I would be interested to know how many universities would cover this type of bioinformatic content in their first or second years.

The DP coordinators view: math internal assessment

Originally posted on May 1, 2020 @ 9:35 pm

I am not a maths teacher let alone an IBDP math teacher and I write this blog well aware of this fact.

The continuing COVID-19 enforced school closures are now beginning to impact the teaching and learning of the May 2021 cohort, particularly in those areas where school campuses have been closed since January. Many students in this cohort appear set to have had almost half of their first year delivered online.

In this post I am not concerned with the actual content of IBDP courses and how that will be addressed, but with the planning of our internal assessment calendar for the May 2021 cohort.

One of the impacts on our campus will be, for a variety of reasons, the combining of IBDP maths courses in each year level. When the new maths courses were published this was something I hoped we would do.

Unfortunately, or fortunately depending on your opinion, that was not to be. I was not able to convince colleagues that the new courses should be combined SL/HL  where possible, with common content for all four courses taught collaboratively.

But now it looks like from next year we will be forced to combine them. I am secretly hopeful that this may open a few minds as we experiment with this paradigm.

The Group 5 project?

Teaching and learning aside, what has this got to do with the IA?

Well, I am currently trying to re-design our coursework calendar for the May 2021 cohort as the picture has shifted now the campus has been closed so long and the calendar designed last October is no longer fit for purpose.

One thing that I especially want to avoid is the concertina of assessment deadlines being squished into the first six months of next academic year. Therefore I am actively looking for solutions to address this, one of which might be fence-posting out the dates the times that all maths classes at all course (AA & AI) & level (SL & HL).

For example, the Math exploration should take 10-15 hours of instructional time. Assuming 15 hours, and with 5 x 1 hour classes per week I could block out three weeks from the middle of October until the middle of November for students to focus purely on their maths IA.

No other subjects can set deadlines for coursework in this time that could distract from students focusing on their maths explorations. All maths classes work on their exploration solely at this time. At the end of this time the first draft of the work would be submitted to their teachers for feedback as per IB rules. Teachers could then have two weeks to turn around their feedback and students a further three weeks to work on their final drafts independently.

To my mind the question is:

  1. Is it feasible to expect all maths classes to work on their explorations in exactly the same weeks?
  2. If so, would this approach allow the collapsing of classes so that students can collaborate, teachers can co-teach and support?
  3. If so, would there be increased opportunities for ATL skill and learner profile attribute development?

IBDP Maths teachers out there, I welcome your views. What is your experience with the new courses and the new IA? Would it be feasible to structure the IA like this?

Philosophy 4 Children

Originally posted on June 4, 2019 @ 9:48 am

This week on Sunday and Monday I took part in Philosophy 4 Children training at our campus. One of our curriculum objectives in Secondary is embed the concepts of Theory of Knowledge (a core component in the IB Diploma Programme) horiztonally and vertically through the Secondary Curriculum. The TOK course is concerned with developing students conceptual understanding of how knowledge is produced and utilized across the subject areas. It challenges kids to think about how knowledge claims can be justified and supported.

At the same time, our primary colleagues have been exploring how Philosophy for Children (P4C) can be used to improve children’s abilities to reason, justify and explain their ideas about broad topics.

One of the benefits of working in a K-12 school is that we can combine PD between Primary and Secondary which allows for some eye opening sharing of teacher classroom practice. This training provided a good opportunity for me as a curriculum leader to not only learn about P4C as a concept and teaching tool, but also to see how it might enable Secondary teachers to get a better grip of managing dialogue and understanding of abstract concepts in the TOK course.

During the training we encountered a variety of warm up activities that can be used to get thinking and discussion going, as well as a full P4C inquiry which is a structured 11 step process for generating a conversation about an abstract question. I am not going to write up all the activities that we did in this post as I tweeted an ongoing thread throughout the training detailing all of the tasks we used.

The first observation I had was that the P4C model of inquiry is highly structured, providing a scaffold for all learners (teachers included) to work through their thinking about a topic. Following the 11 steps from a real stimulus to a discussion about an abstract concept allows even someone who is relatively unconfident in this area to succeed in generating thinking and discussion.

Commentators who were following my thread were quick to point out that int there experience, P4C training was some of the best training for TOK teaching that was available.

Indeed, it became immediately apparent to me that the 11 step full inquiry is a perfect model for generating knowledge questions, one of the key, and most difficult steps for TOK learners to get. Here is a method that can be directly applied in TOK classrooms to help students unpack knowledge questions from a stimulus or real life situation. With practice, I am confident that many teachers would be able to use this model to help them develop TOK thinking.

In other secondary subjects, this model can also help teachers and students to unpack TOK concepts related to their subject area. For example in natural sciences, some of the key TOK concepts relate to models, uncertainty, inductive and deductive reasoning, falsifiability among others. Using the NoS statements from the subject guides with specific real life examples like models used to predict climate change as a stimulus, this model could be directly applied in the IB Biology classroom to help teachers and their students generate knowledge questions from examples in their syllabus.

Recently, I have been thinking about how I can get my IB biology students more engaged with real world issues or deeper conceptual questions like “what is life?”. I have lots of ideas for stimuli but beyond creating a DART or questionnaire linked to the podcast, video or reading I was at a loss as to how to generate deep thinking and discussion.

This tool, I believe, has given me the key to help my students, think about and generate questions in response to stimuli, and provide a basis for fruitful discussion about the topic of interest.

For example, I am thinking about how I can really engage my students with the issue of climate change, so that as well as learning about it from the biology syllabus, the learning develops real meaning and significance for them so that they are inspired to run a CAS project around the issue etc. I had an idea of using some of the recent planet earth documentary as a stimulus but was unsure how to use it. Now, myself, the Lang B teachers and the geography teacher are collaboratively planning to address this topic in sequence and we will think about how we can bring the 11 steps inquiry into our planning.

I am convinced that P4C is an excellent foundation for TOK, both of which are programs that can help student think and question more deeply as well as become more engaged with big ideas and questions.

P4C is broad, it is concerned with thinking about any of a range of concepts that could be thought of as philosophical. TOK is narrower in focus, and, in a Venn diagram, would sit inside the concepts of P4C. P4C can be focussed on knowledge, TOK is concerned only with inquiry about the nature of knowledge. Both programs are concerned with linking the real world stimulus to the abstract theoretical concept. The P4C 11 step scaffold provides an excellent ladder to allow learners to move between the real and the abstract.
