The New IB Math Curriculum

The New IB Math Curriculum

To address the needs of a modern classroom and to ensure that each subject equips students with the tools required to succeed in the changing world, the International Baccalaureate (IB) reviews the IB Diploma Programme (IBDP) on a seven-year teaching cycle. This is why, from August 2019, IB students will study the revised IBDP math syllabus so that they can cultivate a more informed and applied environment of learning as compared to years of textbook education.
The new curriculum aims to make them more adept at critical thinking in mathematics since technological advances are making some skills redundant. In addition to this, the new math DP offers students more choice as well as offering schools greater flexibility in the way they group students, schedule lessons and teach math content.

What exactly has changed?
Previously, an IB student had three options–generalised math at a higher level (HL), at a standard level (SL) or Math Studies. There was also the option of further math at HL, which is rarely offered in IB schools in India. However, with the new syllabus, students have a total of four options–Mathematics: Analysis and Approaches or Mathematics: Applications and Interpretation, each offered at HL and SL. Here is a breakdown of the subjects.

What is the difference between the two streams and what should students choose?
Broadly, the analysis stream is considered more pure and “abstract”, while the applications option is more “applied”.
When studying analysis and approaches, students will focus on honing their math skills, problem-solving and exploring real and abstract applications. This is suited for students who wish to study mathematics at college or subjects that require a deep knowledge of math. This will be taught with and without technology. Analysis and approaches at either SL or HL is ideal for students who are interested in studying mathematics, engineering, physical sciences, and some economics.
In comparison, the applications and interpretation option is for students who wish to solve real problems using math. The emphasis here will be on exploring mathematical models and understanding the practical components of the subject. Students interested in studying social sciences, natural
sciences, medicine, statistics, business, engineering, some economics, psychology, and design in college should opt for 
applications and interpretation at SL or HL.
There are broad guidelines on the IB website that indicate which stream of math would be suitable for which type of student. 

What are the external assessments?
Both these streams, either at SL or HL will have two written final exam papers, consisting of short and long answers. Additionally, HL students will have an extra Paper 3, which will be a one-hour problem-solving paper, possibly requiring the use of spreadsheets and graphing software.

Are the internal assessments going to change?
The main difference in the Internal Assessment (IA) is that the previous Project is changing to Exploration. Students will now spend 30 hours developing investigational, problem-solving, collaboration and modelling skills; the culmination of which will be assessed through an IA component. An independent exploration of an area of mathematics chosen by the student, the IA is internally assessed by the teacher and externally moderated by the IB and contributes to 20 percent to the overall mark.

In order to build an authentic understanding of the subject, the IB aims to create immersive situations within the classroom so that students can apply the theory that they have learnt. The new IBDP mathematics syllabus will focus on developing the skills of analysis, abstraction and generalization, risk awareness and statistical literacy, algorithmic thinking, modelling and inquiry.

All in all, the new curriculum encourages the core belief of the IB pedagogy of ‘learning through inquiry’. As Ibrahim Wazir, Math IB Chief Examiner summarises, “Rather than offering [students]  “rules” to follow, they should be introduced to concepts in an inquiry-based approach. They must see for themselves how a concept is ‘discovered’ and developed into a block that fits into the whole structure of Mathematical knowledge.”

The fundamental role of independent educational consultants is to help students explore college opportunities and find the right place for them to succeed academically and socially. IECs don’t get students admitted—they help students demonstrate why they deserve to be admitted at appropriately chosen schools. They help students find colleges they might not have heard of—often out of their region—and they help students put their best foot forward.

Here are 5 things families should consider when looking to hire an IEC:

  1. Does the IEC belong to a professional association such as IECA with established and rigorous standards for membership?
  2. Do not trust any offers of guaranteed admission to a school or a certain minimum dollar value in scholarships.
  3. Ensure that the IEC adheres to the ethical guidelines for private counseling established by IECA.
  4. Find an IEC that visits college, school, and program campuses and meets with admissions representatives regularly in order to keep up with new trends, academic changes and evolving campus cultures.
  5. Do they attend professional conferences or training workshops on a regular basis to keep up with regional and national trends and changes in the law?
