IA & Practical work

The new IB curriculum changes the way in which students are assessed for their course work – practical assessment. This course work is weighted to contribute about 24% of the final grade. Previously, students completed a wide range of investigations in their PSOW (Practical Scheme of Work), all of which were written up and then assessed internally, before external moderation by the IB. Now students complete a single but very detailed and deep investigation of their choice. This investigation is assessed internally and is the only piece of course work sent to the IB for moderation.

The assessment criteria are significantly different in the new curriculum – see below.

All students must still complete a range of other practical investigations, including 6 (SL) or 7 (HL) obligatory practicals (see below), which are tested in Paper 3. SL students must undertake a total of 40 hours of practical work over the 2 years, and HL students, 60 hours, including the 10 hours of the Group 4 collaborative project.


PRACTICAL SUGGESTIONS FROM THE CURRICULUM GUIDE

This is a list of all the possible practical skills and research investigations, or data analysis and interpretation opportunities proposed in the curriculum guide.


OBLIGATORY PRACTICAL INVESTIGATIONS – for testing in Paper 3

These 6 (SL) or 7 (HL) practicals are obligatory. Students are expected to be conversant with the context of the investigations, the procedures and their limitations. Of course, specific results obtained in your lab need not be memorised, but general trends or outcomes should be considered. In the Paper 3 of the written examinations, there will be question(s) about one or more of these practicals.
