INTERNATIONAL BACCALAUREATE DIPLOMA PROGRAMME The International Baccalaureate Diploma Programme is a rigorous pre-university course of studies, leading to examinations that meet the needs of highly motivated secondary school students between ages of 16 and 19 years. The IB Diploma Programmme is a comprehensive two-year curriculum that expresses a holistic view of the student, and which exposes students to two great traditions of learning: the humanities and the sciences. The curriculum is displayed in the shape of a hexagon with six academic areas surrounding the core.
Physics
Students select one subject from each of the six subject groups. At least three and not more than four are taken at higher level (HL); others are studied at standard level (SL). Candidates must meet three additional requirements. (1) They must take the interdisciplinary Theory of Knowledge course (which is designed to develop a coherent approach to learning, which transcends and unifies the academic areas). (2) They must prepare a 4000 word extended essay—an in depth investigation into one of their subject areas. (3) Students must participate in the creativity, action, and service requirements (CAS), which encourage them to be involved in artistic pursuits, sports and community service work.

THE IB PHYSICS COURSE Group 4 is the experimental sciences group of subjects, and this includes: biology, chemistry, physics and design technology. All courses are intended to be taught over a two-year period. Higher courses cover a minimum of 240 hours of class time, while standard courses cover a minimum of 150 hours of class time. For both standard and higher level courses, about 25% of class time is to be spent on practical work, including a group 4 project. Higher Level Physics Total teaching time in hours............ 240

The I.B. Physics Syllabus is a basic physics survey course. Students should be able to study IB physics with no physics background; only a knowledge of algebra and trigonometry is required. The CORE syllabus material is common to both SL and HL. Both levels study this material to the same depth. ADDITIONAL HIGHER LEVEL
HL = SL + AHL CORE SL Depth

addition, all students must study two of a number of

optional topics. There are STANDARD LEVEL ONLY OPTIONS. This is because most of the material here is common to the AHL material. There are OPTIONS FOR SL AND HL, with higher level extension material. And there are HIGHER LEVEL ONLY OPTIONS. A brief overview of the syllabus follows.

Internal Assessment Teachers set and assign a variety of investigations (traditionally known as ‘laboratory work’). There are five assessment criteria. Not all labs are appropriate to all criteria. A selection of student work is sent into the IB for moderation, where the teacher’s assessment of only the first three criteria is checked. The five criteria are: Design (D), Data Collection and Processing (DCP), Conclusion and Evaluation (CE), Manipulative Skills (MS), and Personal Skills (PS). The three criteria D, DCP and CE will each be assessed at least twice. PS will be assessed only once, and this will be during the group 4 project. MS will be assessed summatively over the whole course and the assessment should be based on a wide range of manipulative skills. Each of the assessment criteria can be separated into three aspects. Descriptors are provided to indicate what is expected in order to meet the requirements of a given aspect completely (c) and partially (p). A description is also given for circumstances in which the requirements are not satisfied, not at all (n). A complete is awarded 2 marks, a partial 1 mark, and a not at all 0 marks. The maximum mark for each criterion is c + c + c or 6 marks. The first three criteria are marked at least twice (if more, then the two highest marks are used) so D, DCP and CE add up to a maximum of 36 marks; PS is taken once for a maximum of 6 marks as is MS for 6 marks. The grand total is then 48 marks for IA. IB_Physics.doc, Page 8 of 11
Examinations After the two-year course of study, students take a comprehensive set of examinations. Their overall grade is based on three exam papers plus internal assessment. The IB grade scale is from the minimum of 1 to the maximum of 7, where 1 = very poor, 2 = poor, 3 = mediocre, 4 = satisfactory (passing), 5 = good , 6 = very good , 7 = excellent.
