The Comprehensive Guide to the International Baccalaureate (IB) Math Grading Procedure: A Breakdown of Internal and External Assessments
The International Baccalaureate (IB) Math grading procedure involves a combination of internal and external assessments, which are designed to measure a student's understanding of the subject matter and their ability to apply mathematical concepts and methods to solve problems.
Internal Assessments:
1. Exploration: This is a project where students are required to investigate a mathematical topic of their own choice. The project is assessed internally and graded on a scale of 0 to 20.
2. Mathematical Reflections: This is a reflective piece of writing where students are required to write about a particular aspect of mathematics that they have studied. This is also assessed internally and graded on a scale of 0 to 6.
External Assessments:
1. Paper 1: This is a 1 hour and 30-minute examination where students are required to answer 16 multiple-choice questions. This paper is worth 30% of the total grade.
2. Paper 2: This is a 2 hour and 30-minute examination where students are required to answer six extended-response questions. This paper is worth 50% of the total grade.
3. Paper 3: This is a 1 hour and 20-minute examination where students are required to answer four extended-response questions based on a specific option they have chosen. This paper is worth 20% of the total grade.
Overall, the IB Math grading procedure involves combining the scores from the internal assessments (exploration and mathematical reflections) and the external assessments (paper 1, paper 2, and paper 3) to arrive at a final score. The final score is then converted into a grade using a set of predefined grade boundaries. The highest possible grade is a 7, while the lowest passing grade is a 3.
