The effect of realistic mathematics education on the problem-solving competency of high school students through learning calculus topics

Abstract

Fostering and developing students’ problem-solving competency is one of the main goals of most mathematics education in the world. Problem-solving competency has been used by the Program for International Student Assessment (PISA) to assess students at the age of 15 since PISA 2003. In Vietnam, new research directions to improve problem-solving competency for students through teaching analytic topics is quite small and not systematic. The purpose of the article is to propose a process of teaching calculus topics in high schools based on the realistic mathematics education approach and problem-solving process according to PISA framework 2021 (OECD, 2018). This design is to support teachers in improving problem-solving competency for students, meeting the requirements of the 2018 general education curriculum in Vietnam today.
