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.

Download (PDF, 70KB)

  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.

Parental engagement with learning

Originally posted on June 7, 2019 @ 3:07 pm

Notes from pre sessional reading of NPQSL session 4, leading affective partnerships. The pre-reading was the report Engaging parents in raising achievement Do parents know they matter?”

Underpining this policy is the central tennet that parental engagement makes a significant difference to the educational outcomes of you people and that parents have a key role to play in raising educational standards.

Reference to Every Parent Matters (DofE 2007)

In demonstrating that families have a major influence on their children’s achievement in school and through life. When schools, families and community work together to support learning, children often do better in school, stay in school longer and like school more.

Parents have the greatest influence on the achievement of young people through supporting their learning in the home rather than supporting activities in the school – parental involvement rather than parental engagement. Activities not directly connected to learning have little impact on pupil achievement.

Schools that offer bespoke forms of support to these parents (i.e. literacy classess, parenting skill support) are more likely to engage them in their child’s learning. Schools should constantly reinforce the fact that parents matter. (For the DP it is important to make the parents feel included).

There are barriers to engaging parents such as lack of time, language barriers, child care issues and practical skills such as literacy issues and the ability to understand and negotiate the school system.

How can the DP program engage parents to help students learn? Parental engagement and personalising provision for them as learners could be NPQH project! 🙂 We need parent and student voice.

The empirical evidence shows that parental involvement in learning is one of the key factors in securing higher student achievement and sustained school performance (Harris and Chrispeels 2006).

Longitudinal studies such as those conducted by Sylvia et al (1999) and Meluish et al (2001) provide the most recent research evidence about parental involvement. These studies reinforce the impact of parental involvement in learning activities in the home with better cognitive achievement, particularly in the early years. In contrast parental involvement acted out in the school confers little or no real benefit on the individual child, though it is valuavle for the schools and parents in terms of community relations.

Parental involvement takes many forms including good parenting in the home, including the provision of a secure and stable environment, intellectual stimulation, parent-child discussion, good models of constructive social and educational values and high aspiration relating to personal fulfillment and good citizenship; contact with schools to share information, participation in school events, participation in the work of the school, and participation in school governance.

This is because parental involvement inititative presuppose that schools, aprents and student are relatively homogenous and equaly willing and capable of developing parental involvement schemes, which is not always the case. We need to be mindfull of the differences between parents.

Mothers feel more involved than fathers. Primary more than secondary. Whilst many paretns wanted to increase their involvement to include for example supporting extra-curricular initiative, they felt that the main barriers to further involvement were limitations on their own time.

Individuals with positional ambition increased their education further in order to maintain a relative advantage. As Lupton (2006) points out ‘most working class parents think education is important but they see it as something that happens in the school and not the home’.

Across all groups, students did better if their parents helped them see the importance of taking advanced science and maths courses and took them to exhibitions, science fairs and the like. Parents who are more involved with their adolescents schooling, regardless of parents gender or educational level have offspring who do better in schools irrespective of the child’s gender, ethnicity and family structure.

Parental involvement, especially in the form of parental values and aspirations modelling in the home is a major positive force shaping students achievement and adjustment.

Working class parents face certain institutional barreiers as schools are middle class institutions with their own values. If the IB is western organization to what extent does the IB philosophy act as a barrier to parental involvement?

Schools that succeed in engaging families from very diverse background share certain key practices. They focus on building trusting collborative relationships among teachers, families, and community members; they recongnise, respect and address families needs as well as class and cultural differences. There needs to be strategic planning which embeds parental involvement schemes in whole school development planning.

Help parents understand elements of the curriculum, advice about revision techniques at KS3 and 4 as well as more divers activities designed to stimulate parental engagement with schools and raise parents aspirations for their children.

How can we get DP parents into school?. Dads and lads maths events, centering on cars and football. family learning events and helping parents understand the contemporary curriculum and homework/coursework. Parents attending parent and child learning events. or attend help your child learn courses. Booklets for parents on the same subject and allowing parents to shadow a year group during a school day to experience contemporary schooling for themselves.

Courses on parenting, on family issues, these events provided not only expert advice from teachers or other agencies (Parent Line) but allowed parents to discuss family and learning related issues with peers. Their focus was on the parent-child relationship. The provision of parent handbooks was also successful; parents reported satisfaction with the availability of information and the ease of finding the information needed. Schools engaged mentors for students and supported both students and their parents about issues of attendance and punctuaity. A number of schools targeted year six pupils and parents offering support and pastoral care around transition for both groups. Other schools responded to parental requests for support in specific areas.

Some schools did institute a cycle of “you said, we did”, and found that increased parental engagement with the school. Other schools made it clear in their reports that their conception of intelligent reporting was still a front ended one, originating with the school and ending with the parent. Schools have reduced and simplified their reports to parents, on the basis of parental preference; language used in reports has been made consistent and staff workload reduced, as reports are shorter and more to the point, staff have agreed that the new systems instituted are a different way of working, rather than more work. Parents can now access online, real time data for their own children, leading to family conversations with have had a beneficial effect on behaviour.

Parental engagement is not about engaging with the school but with the learning of the child. We could give a weekly coordinators learner profile award, voted for on Friday. Awarded on Monday.

Student don’t seek parental engagement with school activities but engagement and participation in their learning. Parental engagement policy? Homework policy in the DP?

Students were very clear that parental interest in their education had a direct and positive effect on in-school behaviour. Good behaviour was not reinforced and bad behaviour was not punished.

Homework – either in terms of monitoring it or helping with it – came from far down the list of activities valued by students and yet it is often the way that parental engagement is understood.

The data suggests that while involvement in homework is of value, in and of itself it doesn’t fulfll the prescriptions of students needs. Rather it is the beginning of the process that should lead to deeper discussions.

When parents feel that they have the opportunities, skills and knowledge required to help their children, they are more likely to be engaged. Such reluctance or reticence on the part of parents is a powerful signal to their children that education is not valued or indeed valuable.

The role of curriculum

Originally posted on April 13, 2019 @ 10:00 am

In the second NPQSL face to face session we looked at leading the quality of teaching and learning within a school. We were asked to think about what high quality teaching and learning looks like in our schools and what this means to us personally. This provided some good reflection time for my own thinking about this means for me. I concluded that high quality teaching and learning is where students are forced into thinking about the topics of the subject under discussion. Thinking takes variety of forms. For me and my project, focused on implementing the DP, TOK is the key to horizontal collaboration within the DP programme, catalyzing not only a change in the way that student think but also how teachers think. Going forward I need to Establish a working group of teachers who are interested in improving their links to TOK.

At the start of the session on “driving the quality of teaching and learning” we were asked to list three priorities with regard to the quality of teaching and learning. Mine were:

  1. Making thinking the basis of both
  2. Developing good knowledge of the whole curriculum (Martin Robinson’s story)
  3. Developing knowledge of good practice – can the teacher make reasoned judgements about why they do what they do.

We then considered learning centered leadership: – how do we model, monitor and have dialogue. My group felt that it was important for leaders to be:

  1. Modelling preparedness, calm, openness and friendliness
  2. Still teaching?
  3. Using data
  4. Observations
  5. Conversations
  6. Diagnostic audit of peoples and there skills

Next we were asked to list ten ingredients for great teaching and to discuss why leaders may want to observe lessons, what the purposes of lesson observation were. My ingredients for great teaching were:

  1. Dialog
  2. Content knowledge
  3. Pedagogical content knowledge
  4. Evidence for teaching practice
  5. Prior knowledge
  6. Contextual – relevance for kids
  7. Focussed on concepts
  8. Timing – knowing when an intervention is appropriate or not
  9. Collaborative – outside the silo
  10. Firm friendliness

I also felt that observation is a great way to learn and be coached and time for teachers to observe each other is valuable if we want to enable coaching, mentoring and further development.

After sharing these within our groups we had to decide on the groups final five. We had a lot of good discussion about how learning is often confused with performance and other proxies, and that learning is actually quite a hard thing to actually observe in a lesson. Any attempt to observe a lesson for accountability purposes was doomed if you are hoping to look measure learning. Instead my group agreed that the best we could hope for was to look for proxies that may indicate high quality teaching. My group decided that our priorities were to look for :

  1. Positive relationships
  2. Feedback
  3. Knowing the students
  4. Knowledge of content and pedagogy
  5. High Expectations

I reflected that evidence is a key thing here: Knowledge in education is so tentative and unsure that no one can say with certainty this is right, or this way is wrong. Thus if we focus on the thinking behind what teachers are doing and why – are teachers able to engage with discussions and evidence why they are doing somethingt. To ensure great teaching I think it is important for leaders to smile, be open and approachable. We need to encourage discussion between teachers about their practice, provide opportunity for observation between teachers and focus more on teaching and learning, instead of getting drag into secondary tasks.

Going forward I need to work to facilitate this in my community and help to provide opportunity for this to happen, time for teachers to observe each other and time for them to have discussions with a view to improving the quality of teaching within the school. I need to support a focus on developing an understanding of the links between the subjects – horizontally and vertically – and encourage teachers to come out of the their silo.

How might this session influence your staff professional development policy?

How can you measure the impact of CPD? Carry out observations of trying out TOK activities, carry out a staff survey, have the CPD, start the written curriculum and then observe more activities and carry out an additional survey. Invite staff to take part in TOK and ATL collaboration.
