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 Knowledge, a 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.
Great Q..I think i would take a function & then structure approach, less prop knowledge in function, build the schema around that, structure incl enzymes I 'think' fits around this more effectively

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.
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?
