IB SUBJECTS GROUP 4 COMPUTER SCIENCE Computer science is an experimental science that offers a rigorous and practical problem- solving discipline, which, as a methodology, can be applied to all walks of life. Computer science requires an understanding of the fundamental concepts of computational thinking as well as knowledge of how computers and other digital devices operate. Course content: The topics that must be studied, including some practical work, are: Topic 1 System fundamentals (20 hours) Topic 2 Computer organisation (6 hours) Topic 3 Networks (9 hours) Topic 4 Computational thinking, problem-solving and programming (45 hours) Group 5 Subjects: Mathematics Entry requirements: Students will be able to study computer science at SL successfully with no background in, or previous knowledge of, computer science. Students would be expected to have some prior knowledge and understanding of computing. However, applications will be considered from pupils without such a background where their approach to study aligns strongly with the IB learner profile attributes, especially in terms of being inquirers, thinkers and communicators. The study of computer science at HL demands a higher level of problem-solving skills and the ability to understand and manipulate abstract concepts. Some exposure to programming is desirable. HL extension The topics that must be studied, including some practical work, are: Topic 5 Abstract data structures (23 hours) Topic 6 Resource management (8 hours) Topic 7 Control (14 hours) Case study IB SUBJECTS GROUP 5 Course assessment: There are three examination papers covering 80% of the final mark. Pupils also produce an internal assessment in which they write about a computational solution they have developed. As with other Group 4 subjects, there is a project to complete in school. This project, plus the internal assessment make up the other 20% of the final mark. Everyone uses mathematics on a regular basis, as part of their everyday life, during such activities as buying produce, consulting a timetable, and estimating measures. From this vast population, there is a group of people who use mathematics to a greater degree and apply their knowledge to specific tasks. These include bank staff, surveyors, laboratory technicians and secretaries. People such as architects, engineers, economists, pilots, and designers use mathematics at a more specialised level. Further, there is a smaller group of people who are professional mathematicians involved in research, statistics and branches of science. For all three mathematics courses, pupils are required to purchase a graphics display calculator (GDC). It is recommended that pupils purchase a Texas Instruments TI-Nspire CX GDC to get the most out of their IB mathematics course. MATHEMATICAL STUDIES (SL) This course is recommended for pupils who have attained (or are likely to attain) a grade B or grade C at IGCSE mathematics. This course is also suited to pupils who wish to pursue a course at university with little mathematical content, such as social sciences, humanities, languages or the arts. Course aims and content: This course is available only at standard level, and is equivalent in status to mathematics SL, but addresses different needs. It has an emphasis on applications of mathematics, particularly statistical techniques. It offers pupils opportunities to learn important concepts and techniques, and to gain an understanding of a wide variety of mathematical topics. It prepares pupils to be able to solve problems in a variety of settings, to develop more sophisticated mathematical reasoning, and to enhance their critical thinking. Course assessment: This course is assessed by means of two written examinations, paper 1 and paper 2, both of which are 90 minutes in length, scored out of 90, and are calculator based. The written examinations count for 80% of the final grade. The other 20% comes from the internal assessment, an individual piece of written work on an area of mathematics that utilises some of the skills that pupils have learned during the course. Additional subject content is introduced by the annually issued case study 24 25
