Curriculum coherence. The case of linear equations in a Costa Rican textbook

Abstract

This research analyzes the relationship of curricular coherence between the tasks of an eighth-grade textbook on the subject of linear equations of the mathematics subject and the detailed guidelines in the study programs in Costa Rica. Since it seeks to address a particular situation in Costa Rican education, the analysis consists of a case study with a qualitative approach on a specific topic in order to achieve a better degree of understanding about the design of tasks that guide the learning of mathematics at the secondary level. As a result, the relationship that the tasks in the subject of equations show with the basis and foundations of the study program is detailed, including the active role of the student in their learning process, as well as elements such as the use of history and technology, skills and others. The results lead us to the recommendation to strengthen some elements to achieve greater curricular coherence between classroom activities and the mathematics study program in eighth grade, such as the inclusion of playful activities for learning equations.
