From Knowledge to Understandings

Originally posted on April 2, 2018 @ 9:00 am

Recently (when I first started this post at least) I blogged about the best way to begin the DP biology syllabus and I was frustrated by the limitations of the syllabus to be able to pick and choose different assessment statements.

The DP biology course has always been knowledge rich. Maybe not as full as the A Level syllabus to take account of the fact that students are taking six subjects plus a summatively assessed course in Theory of Knowledgea summatively assessed research project: The Extended Essay, and their Creativity, Activity and Service Program.

Now, the IB changed the syllabus to allow more conceptual teaching, by removing the series of statements about students should be able to:… “explain x” and “state y” and grouping knowledge into brief statements under the heading of understandings, applications and skills. However, the structure of the syllabus with the essential idea for each topic tends to hamper the ability to lift assessment statements out and add them to new areas. i.e. mutations and oncogenes in topic 1.6 could be taught with topics 3.1 after 2.6. See the biology guide for the full IB syllabus.

This year, my Diploma Programme Coordinator, asked the subject departments to focus on developing their written curriculum.

It seemed timely to be asked to do this, when over the summer I had been musing about the best place to begin the course and the best ways to break up the different topics – many of the schools I have worked in simply teach the course topic by topic and the IB is keen to point out in the biology guide:

The order in which the syllabus is arranged is not the order in which it should be taught, and it is up to individual teachers to decide on an arrangement that suits their circumstances. Sections of the option material may be taught within the core or the additional higher level (AHL) material if desired or the option material can be taught as a separate unit.”

Over the course of this academic year, I have thought a lot about how best to structure the course to allow the “best” progression of concepts. Actually, I think that this is a process that began when I first started teaching my current Y13s, and I am an exceptionally slow thinker! I do remember reflecting on how to best position evolution within the course and which topics would be best coming before or after it.

But it wasn’t until this year that I have had the time within my working week or the emotional time within my personal life to really dig down and get to grips with writing up my ideas into the formal IB course outline.

I have also been exposed to new ideas about teaching and learning over the last twelve months. Last summer I read Dan Willingham’s book “Why don’t students like school?” which I think I got put onto after reading Michela’s “Battle Hymn of the Tiger Teachers”.

Idea’s from cognitive science have become more and more prevalent on my twitter feed as well as I have started to interact a little more with the #CogSciSci crowd.

All this to say that my thinking has evolved in the last twelve months.

I now know that, generally speaking, content knowledge, concepts and skills are domain specific and that learners have to become fluent with a subject’s facts before they are able to transfer that to abstract concepts and develop understanding let alone build connections with other subjects.

I am also beginning to understand the concepts of retrieval practice, spaced practice, dual coding and the distinctions between declarative knowledge and procedural knowledge and how all this may apply to my subject teaching or pedagogical content knowledge as Lucy Crehan puts it in “Clever Lands”.

Translating this into biology teaching is still not well understood (or so it seems from my vantage point) but conversations like the ones below (propositional knowledge = declarative knowledge) and blogs like this one, are beginning to help me unpack this.

The finished product

The below is the finished course outline that details the units and sequence of the teaching of the course. It is an official document used in the authorization and evaluation process of IB World Schools.

The below is my SOW for the course. It has six tabs. The DP overview shows the number of teaching hours recommended by the IB for each subtopic along with my grouping of them per unit. The Year overview shows the spacing of the units through time for both Y12/Y13. The next two tabs are for the week to week (mid-term planning). The Bio and TOK tabs show the TOK links that I have chosen to focus on the topic and are to support collaborative planning with the TOK team. Finally, the PSOW tab shows the practicals that can be built into the course. The IB mandates a specific number of practical hours for both SL and HL courses.

Final Word

The other effect of this learning for me is that I am now worried about the direction that the IB is taking in its philosophy.

If research from cognitive science is telling us that learners need a solid factual knowledge base before they can build conceptual understanding then what does this say for a course whose syllabus is about “understandings” as opposed to knowledge?

I have not heard anything from the IB that shows that it is reviewing research from cognitive science. Is the IB becoming an ideologically run institution that ignores research that doesn’t fit in with its own paradigm?

Routines

Originally posted on October 22, 2017 @ 9:00 am

I was planning on publishing this post in August, but term got away with me!

Next year, I want to really focus on developing solid classroom routines. I am amazed at how I have got to year 10 of my teaching career and it has only been in the last twelve months that I have begun to see the importance of these for running even older classrooms.

Perhaps it is the peculiarity of my current school, with a high turnover of students and my experiences of having dramatic changes in the makeup of each cohort year on year, alongside changes to curriculum time and with a wide range of student backgrounds, and language proficiencies.

Last year I focused on thinking routines and I think the adoption of some of these exercises has been very beneficial for my students, the trick is sticking to them! But reflecting on this process, talking to colleagues and reading Battle Hymn has really highlighted the necessity of routines for all aspects of classroom management.

My one concern is that reliance on routines will make the classroom boring but I also think that routines have the potential to create safe spaces, where all students understand easily what is required of them. Used well they can remove distractions from students and increase the efficiency of learning.

The idea is essentially utilitarian; serve the greater good. Create space for the majority to learn.

The trouble is, our school has been open for four years now and every year, management has changed how we do things, in terms of the number of lessons available per week per subject, or the length of lessons. Don’t get me wrong, change can be good and it is important to try and improve things. However, change that isn’t tested and thought through can have negative consequences, as can too much change.

Routines need to be simple and rewards and sanctions just as simple. An overcomplicated system just creates more work for everybody.

Thinking: This year I will continue to embed the visible thinking routines as defined by project zero into classroom activities. I use connect-extend-challenge all the time and may need to revisit how I implement it. In discussions with colleagues recently about best prepparing students to write personal statements, I have also been introduced to the point-evidence-explain for structuring writing. As a science teacher, who hasn’t had much training in writing, or as a science teacher who hardly ever has student’s writing essays, it is interesting observing internally how that type of routine can easily be adopted to embed thinking about an argument.

Behaviour management: This year, our school has implemented a “behaviour policy”. Although we don’t suffer from extremely poor behaviour, I have been frustrated by students regularly not turning up to class on time, not having the materials they need with them and generally not taking responsibility for their own development.

EAL: My simple model for lesson planning: 1) 10 mins of low-stakes quizzing in some form; 2) 30 mins of teaching/learning activities; 3) 10 mins of written plenary. I haven’t been brilliant at sticking to this plan throughout this half of last term but the idea of the last part was to give my EAL kids a chance to do some formal writing in English. Other rountines that I am trying to develop for my EAL kids is to write new terms on the side of the board. I collate these into quizlet and ask kids to keep their own glossary ot terms. I also am trying to narrate much more of what I do in the classroom so that my thinking is clearly visible to these students.

Intensive EAL support and differentiation in Biology

Originally posted on August 13, 2017 @ 9:00 am

As an international teacher, I am familiar with EAL or Lang B students in my classes, and familiar with how to support them in my Biology classes which, more than even some of the other science subjects, has a lot of context-specific terminology that cannot be simplified. These terms can be almost impossible to simplify form non-native speakers but repeated INSET training has told me that I must. Some examples would include:

  • Heterozygosity
  • Anyone of the Animal or Plant Phyla students are required to know
  • Proteome
  • Clade
  • Oxidative Phosphorylation
  • Photolysis
  • Inhibitor
  • Eukaryote
  • Archaea
  • Transpiration
  • Cohesion

There are many more…

This past academic year I had a particularly difficult situation to deal with in my grade 10 biology class.

Grade 10 is the final year of the MYP and is equivalent to Year 11 in the U.K. My current school is very small, tiny in fact, by the nature that it has only been open four years.

As a new school in a competitive area we have a battle to recruit students. As an international school in an area where lots of families come with the parents work on short term contracts we have a high turn over of students.

Due to these factors, every year of teaching I have had to completely change my scheme of work for this grade and grade nine because of changes in the cohorts of students as well as yearly changes to science teaching hours across the week.

One year I only had brand new students taking grade 10 Biology all of whom had come from Francophone schools and so the MYP 5 course I had planned had to be changed to accommodate these students.

As an international school it can be normal to have turnover in students with many students leaving and new students entering at any grade. Things are also complicated because students may come from different national systems, and may have studied in different languages prior to joining us. It's very hard to comparatively assess the biological knowledge of different students coming from different languages of study and these different systems.

Whereas, last year, all the students in my grade 10 class were new to the school and I had to create a novel one year curriculum for them to ensure that none of the fundamentals from grade 9 were missing, this year I could revert to the original two year program I had planned previously.

This year I had some students who had progressed to grade 10 biology from grade 9 (these grades are planned as a two year consecutive course) internally and were on track to take the MYP eAssessment.

However I also had students placed in the class who came from different schools and were new to studying in English, let alone biology in English. Amongst these students there was variation. One student had absolutely no prior experience using or studying in the English language and others had never studied in the language, academically, but had spent some time of heir lives speaking and communicating with English.

At the start of the year, I was informed that all of these students would be taking the MYP eAssessment (the IB equivalent of GCSE)!

Despite my protestations that these students would not be ready for the eAssessment with only six months of going to an anglophone school, let alone studying biology in English and that they were better off being placed in an intensive EAL program, I was ignored.

The message to me was that I simply had to differentiate for these students! Differentiation is fine but when does differentiation steadily become "plan a whole new program?" What are the practical limitations for a teacher that determine when differentiation should stop and alternative arrangements need to be made.

A similar situation happened to a colleague of mine who teaches French. One year he was told that he would have French A (Literature – native speakers) students mixed in with French B (Aquisition – non-native speakers) and that the teacher would have to differentiate between these two groups.

I am all for differentiation and trying to meet individual students where they are at but I don't like it when it becomes a lazy shield for management to hide behind. Instead of the SLT taking charge and actually putting a proper intervention in place for these students, it is easier to pass the buck to the teacher and simply say "differentiate!" The problem with this is the anxiety, stress and associated mental health issues it will invariably create for staff.

What seemed to be lacking from members of the schools management is the difference between Jim Cummin's BICS and CALPS. Being able to speak in a second language with your friends is one thing, but being able to think about and explain complex, abstract concepts in a second language is quite another. Biology has a huge amount of subject or context-specific terminology that even native speakers can find daunting.

The year hasn't been a great success. Unfortunately some non-negotiables have to be negotiable as there is a limit to what a person can achieve in a day. What this meant for these students is that I simply wasn't able to plan for them as well as I would have liked, with all my additional responsibilities, particularly the running of the university guidance.

I focussed what time I could devote to this class on the students who would be taking the exam and focussed on developing the thinking routines within the class; connect-extend-challenge has become very popular!

However I have been able to learn something from this experience and found that the following techniques could be put in place very easily to support EAL students without too much interruption to the flow of the lesson:

  • Glossaries for every unit that focus on key words. I have started adding them to my DP workbooks as simply a space at the back for students to add their key words and definitions, but for the younger grades I will provide the words and the definitions.
  • Whole-class reading in every lesson. Making solid use of available texts and reading these out gives students a change to practice saying new words and gives me a chance to feedback to them and explain any new terminology.
  • When asking students to explain a concept to check for their understanding, allowing them to write out their ideas in the their mother tongue to support a speaking in the second language.
  • Asking students to write, in English, a short paragraph (3-4 lines) explaining what they learned either at the start of end of a lesson. As the teacher, I can rotate and check grammar, spelling and sentence construction. This is best done by hand as 1) the IB exams are currently written and 2) due to the Lindy effect, writing is likely to be around a lot longer than google docs.
  • Taking care to fully explain the roots of words e.g. "photo" & "synthesis" and giving students time to find the words in their mother-tongue if they have studies this concept before.
  • Allowing students to speak in their mother tongue to each other to aid explanations and comprehension.
  • During explanations given by me, slowing down and, where possible, using simpler language (not always possible in Biology – what is a simpler word for heterozygosity?).
  • Always check for understanding with open questions. "Please can you explain/write/draw this for me?" to show understanding.
  • Use of colours and images to describe tasks so that students become aware that when a symbol of a quill is used it means that they have to write.

Any more advice or ideas welcome in the comments!

What is the best place to start teaching IB DP Biology?

Originally posted on August 20, 2017 @ 9:00 am

Every year I like to think about how I approach the delivery of the DP Biology course. I think about what are the best examples to use to illustrate concepts like the pentadactyl limb, or what is the best way to structure the teaching sequence into a coherent sequence.

This summer I have been thinking about how best to approach the start of the course. I think this is important in my context because I cannot be certain of the biological background of all of my students and I don’t want to make any assumptions about what they know.

I polled teachers on facebook and twitter about this and most teachers tend to start the course with 1.1 – introduction to cells, although other areas like to 2.1 – molecules to metabolism and 5.3 – classification of biodiversity are also popular if not nearly so as 1.1.

My issues with starting at 1.1 is that I think that while there are some essential ideas that are natural to start a Biology course; the functions of life and cell theory, there are others which are not so helpful like stem cells, gene control of differentiation, and evolution of multicellularity. Some of these concepts are tricky to get your head around and do not count as foundational knowledge, in my opinion.

What I want in the start of my DP course is to introduce students to the simplest biological concepts that will go on to serve as a foundation for future learning. I believe the functions of life and the classification of life (“what is life?” and “ok, we know how to crudely define living things, but what types of living things are there?”) are understandings that students should address before going on to look at how living things work.

What I am struggling with is this: the IB’s TSM states that topics don’t need to be taught in order, or that even subtopics don’t necessarily need to be taught in order. We should, as teachers, construct a course that draws different elements into coherent units. Personally, last year, I made a move away from going through topic by topic and tried to link subtopics into themed units. I love thinking about what topics flow well together.

But what if you want to split sub topics? Is this allowable? Obviously you could do this but, with the way the IB has structured the sub-topics each with their own “essential idea”, should you? The issues with the essential idea is that it aims to force all the understandings in that subtopic under a single umbrella. Because the essential idea is examinable, surely all the understandings, applications and skills should be kept together as they serve to illuminate the essential idea.

Personally, I think I may go ahead and chop up 1.1 so that I introduce these:

  • A2: Investigation of functions of life in Paramecium and one named photosynthetic unicellular organism.
  • U2: Organisms consisting of only one cell carry out all functions of life in that cell.

With this from 5.3:

  • U4: All organisms are classified into three domains.

Which will then act as a segway into topic 1.2 the ultrastructure of cells, before going on to consider cell theory and the then the rest of topic 5.3.

Its a little bit pick and mix, but do I run the risk of not covering the essential ideas. To solve that, what I may do is leave the essential ideas  (of these sections) for revision in grade 12. In-fact now I think about it, all the essential ideas would make great revision points.

I could get the students to memorise Allott and Mindorff’s paragraph’s that describe each essential idea and force them to regurgitate them at random points through G12…..

New DP Biology site launched (but still under construction!)

Originally posted on July 28, 2017 @ 12:28 pm

So I have moved over my DP biology resources to a new google site designed for delivering the course. You can view it here: 

In my first school I worked with a colleague who made workbooks for her students, that were tailored to the 2009 syllabus. The kids loved them. At this time I was still working on a paper basis with large lever arch folders, and photocopying the exercises that I wanted to give to my students. To simplify my planning and preparation I thought it would be easier to copy my colleagues idea and collate all of my exercises into workbooks for each subtopic that I could simply print and hand out to my students. It took me a few years to develop these workbooks and then the syllabus changed.

For the first two years of the 2016 syllabus I worked on updating my existing workbooks to bring them in line with the new syllabus. By this point, I had moved school’s twice and had been exposed to quite a few different pedagogical approaches and philosophies, as well as different levels of technological tools with which to teach. It seemed the time had come to convert totally from paper to digital.

I share this website as a resource for other educators and their students but please be aware that, while I certainly welcome discussion, critique and comments, I have designed this website with the following purposes in mind:

    • To consolidate my existing resources and methodology into one digital space.
    • To structure the course that I currently teach to my own students into one place for my own students to access.
    • To provide a structure to the exercises that I use in class. It is NOT intended to be another content heavy IB site

There are plenty of IB Biology content-driven resources out on the web, some of which are truly excellent. This is not intended to be such. Instead the aim is to provide structure and exercises to query and engage with content-driven resources, like website, video and textbooks.

If you wish to feedback please remember that in addition to creating this website I am:

    • A full time teacher with other responsibilities in my professional life and a young family.
    • Preparing this work, primarily for my own personal professional use.
    • Making no claims that their are no mistakes in this website, please check carefully and if you feel so inclined drop me an email to let me know.
    • Making no claims that the exercises, ideas and resources are entirely my own original work. Please see my acknowledgements page for details.

 I am intending to follow this up with a google site dedicated to MYP Biology and another for guidance counseling. I will keep this blog purely for noting down my thoughts when and if they occur!
