In the recent posts we have been focusing on the statistics elements of the new course. It is now time for an update on the general running of the course and the pure elements.
Firstly some background information on the new A-level group. In previous years we have offered the maths A-level in two different option blocks meaning that we have had two groups of around 10 – 12 students. With drop off as students have dropped from four to three subjects at the end of year 12 this has meant groups of 5 – 8 in year 13. This has now been considered uneconomical so we have been reduced to one option block, as it was thought impossible to combine the two groups at the end of year 12. Of course having had this decision imposed on us, we then had a greater take up of maths meaning a class of 26. The balance of this class is also unusual due to a foreign exchange programme meaning that we have a large number of foreign students joining us for the year (two Swedes, two Mexicans, one American and one Romanian). These students will leave at the end of year 12 leaving a much more manageable year 13 group.
In practical terms the sharing of the content evenly has gone extremely well, with us being able to have frequent conversations about the direction of the lessons, despite the added pressure on my time due to being head of department this year. This has been even better than expected, as having the dialogue has meant (certainly for me and I hope for Will), that the actual planning of the lesson has been easier as I already know what I want to achieve. We have been careful to make sure that both of us have taught both pure content and statistics content to avoid being pigeon-holed as the ‘pure’ teacher and the ‘stats’ teacher.
Another positive has been the use of technology in lessons. In the first three weeks of term I have already booked and used a computer room more than I had in the previous two years. All of the students have now got their new calculators and we are settling into using them – I even treated myself to a new one, replacing the one I had used since I did my A-levels 16 years ago.
Our first lesson looked at extending GCSE proof. We felt that it was really important to introduce proof as one of our key themes as early as possible. We asked students to choose from a variety of ideas, both algebraic and geometrical, to see what they could come up with. We then discussed what a proof should look like and worked on developing the skills required to build a mathematical argument. This is something that we will be returning to regularly, making sure that students are getting more accomplished.
Our first major topic was indices and surds. As this is largely revision of GCSE topics we decided to approach it by setting pre-learning tasks and then developing the knowledge already in place. The tasks we set were the ‘walkthroughs’ from Integral Maths. These walk students through the required knowledge of the topic, introducing ideas and allowing experimentation in an interactive way. Students are allowed as many attempts as required without it being recorded and reported to teachers.
For the indices section of the week we used the online textbook ‘Problem Book for A-level Maths’ being developed by Stuart Price (@sxpmaths on Twitter). We really like the way that this has sections for students who are at different stages of development, starting with technique for those who need more work on the basics and progressing through problem solving to puzzles & challenge. Our grade 9 students had great fun going straight onto the challenge problems, while others were absorbed by the technique section. They were also able to move backwards and forwards if required. There is also a final section for each topic which covers exam style question practice, although we did not get to this – something to use in the future.
For the surds section we used an adaptation of an activity from Integral Maths (pictured below) where students discussed how surds are simplified. We deliberately left some expressions that had not been fully simplified and asked students to present their findings to each other. Additional questions for this lesson were taken from Dr Frost Maths (@DrFrostMaths).
We have been really enjoying using materials from a variety of sources and with different styles. Students seem really enthused and have been seeking us out for extra support when needed. Our next topic is exponentials and logarithms. The logic behind this is that we wanted students to experience something totally new early in the course. We also felt that they fitted very well together, essentially being two different ways of looking at the same topic. I always felt that the two ends were rather artificially kept apart by the arbitrary barrier between C1 and C2, now I have the opportunity to try and teach them together.
Hopefully I will have time for an update next week!
