These are: 1. AS Core Mathematics 2. A2 Core Mathematics 3. AS Statistics 4. AS Mechanics 5. AS Decision Mathematics Sections 1 and 2 are based on the QCA Subject Criteria. This document defines all the mathematics that should be included in A-level Mathematics and is used by the examination boards. Every A-level in mathematics must conform to the requirements of this QCA document. The full version of this document can be found at: http://www.qca.org.uk/downloads/5660_maths_revised_subject_criteria_as_a_level.pdf Working through sections 1 and 2 will help you to ensure that you are familiar with the core content for A-level mathematics. When you took your A-level, the core mathematics would probably have been known as pure mathematics. Section 3, 4 and 5 relate to the application areas of A-level mathematics. In this profile we have included a selection of content that is typical of a first module in that application area. As QCA do not define the content of these modules there is quite a bit of variation between the examination boards. In order to overcome this problem, the profile includes more material than would be found in a single AS module, but the list does cover most things that you might be expected to teach in a first module. These sections have been produced with help from the examination boards’ websites. (See below) If you are interested in looking at the content of A2 application modules or further mathematics, it is recommended that you visit one of the examination boards’ websites using one of the links below: http://www.aqa.org.uk/qual/gceasa/mathematics.php http://www.ocr.org.uk/qualifications/AS_ALevelGCEMathematics.html http://www.ocr.org.uk/qualifications/AS_ALevelGCEMathematics(MEI)-NewGCE.html http://www.edexcel.org.uk/quals/gce/maths/adv04/maths/ 14 Section 1 – AS Core Mathematics Familiar with topic Proof Construction and presentation of mathematical arguments through appropriate use of logical deduction and precise statements involving correct use of symbols and appropriate connecting language.
