SYLLABUS DETAILS

Format of the syllabus

The syllabus to be taught is presented as three topics.

Content: the first column lists, under each topic, the sub-topics to be covered.

Amplifications/inclusions: the second column contains more explicit information on specific sub-topics listed in the first column. This helps to define what is required in terms of preparing for the examination.

Exclusions: the third column contains information about what is not required in terms of preparing for the examination.

Although the mathematics HL course is similar in content to parts of the mathematics SL course, there are differences. In particular, students and teachers are expected to take a more sophisticated approach for mathematics HL, during the course and in the examinations. Where appropriate, guidelines are provided in the second and third columns of the syllabus details (as indicated by the phrase gSee SL guideh).

Course of study

Teachers are required to teach all the sub-topics listed for the seven topics in the core, together with all the sub-topics in the chosen option. The topics in the syllabus do not need to be taught in the order in which they appear in this guide. Similarly, it is not necessary to teach all the topics in the core before starting to teach an option. Teachers should therefore construct a course of study that is tailored to the needs of their students and that integrates the areas covered by the syllabus, and, where necessary, the presumed knowledge (PK).

Integration of portfolio assignments

The two pieces of work for the portfolio, based on the two types of tasks (mathematical investigation and mathematical modeling), should be incorporated into the course of study, and should relate directly to topics in the syllabus. Full details of how to do this are given in the section on internal assessment.

Time allocation

The recommended teaching time for higher level courses is 240 hours. For mathematics HL, it is expected that 10 hours will be spent on work for the portfolio. The time allocations given in this guide are approximate, and are intended to suggest how the remaining 230 hours allowed for the teaching of the syllabus might be allocated. However, the exact time spent on each topic depends on a number of factors, including the background knowledge and level of preparedness of each student. Teachers should therefore adjust these timings to correspond to the needs of their students.

Use of calculators

Students are expected to have access to a graphic display calculator (GDC) at all times during the course. The minimum requirements are reviewed as technology advances, and updated information will be provided to schools. It is expected that teachers and schools monitor calculator use with reference to the calculator policy. Regulations covering the types of calculator allowed are provided in the Vade Mecum. Further information and advice is provided in the teacher support material. There are specific requirements for calculators used by students studying the statistics and probability option.

Mathematics HL information booklet

Because each student is required to have access to a clean copy of this booklet during the examination, it is recommended that teachers ensure students are familiar with the contents of this document from the beginning of the course. The booklet is provided by the IBO and is published separately.

Teacher support materials

A variety of teacher support materials will accompany this guide. These materials will include suggestions to help teachers integrate the use of GDCs into their teaching, guidance for teachers on the marking of portfolios, and specimen examination papers and markschemes. These will be distributed to all schools.

External assessment guidelines

It is recommended that teachers familiarize themselves with the section on external assessment guidelines, as this contains important information about the examination papers. In particular, students need to be familiar with notation the IBO uses and the command terms, as these will be used without explanation in the examination papers.

Presumed knowledge

General

Students are not required to be familiar with all the topics listed as PK before they start this course. However, they should be familiar with these topics before they take the examinations, because questions assume knowledge of them. Teachers must therefore ensure that any topics designated as PK that are unknown to their students at the start of the course are included at an early stage. They should also take into account the existing mathematical knowledge of their students to design an appropriate course of study for mathematics HL. This list of topics is not designed to represent the outline of a course that might lead to the mathematics HL course. Instead, it lists the knowledge, together with the syllabus content, that is essential to successful completion of the mathematics HL course.  Students must be familiar with SI (Système International) units of length, mass and time, and their derived units.

Topic 8—Option: Statistics and probability 40 hrs

Aims

The aims of this option are to allow students the opportunity to approach statistics in a practical way; to demonstrate a good level of statistical understanding;

and to understand which situations apply and to interpret the given results. It is expected that GDCs will be used throughout this option and that the minimum

requirement of a GDC will be to find pdf, cdf, inverse cdf, p-values and test statistics including calculations for the following distributions: binomial, Poisson,

normal, t and chi-squared. Students are expected to set up the problem mathematically and then read the answers from the GDC, indicating this within their

written answers. Calculator-specific or brand-specific language should not be used within these explanations.
