PENGEMBANGAN BAHAN AJAR BERBASIS DAPIC PROBLEM SOLVING PROCESS YANG BERORIENTASI PADA KEMAMPUAN LITERASI MATEMATIS

Abstract

The lack of textbooks addressing mathematical literacy skills and poor levels of mathematical literacy are the driving forces for this research. The goal of this study is to assess the level of validity, effectivity, and applicability of teaching materials based on the DAPIC problem-solving procedure that are targeted at students' mathematical literacy abilities in the area of flat-sided space creation. Design-based Research (DbR) with the Plomp model is the research methodology used. Ten respondents and two validators served as the study's data sources. Validation sheets, Literacy skill tests, and student response surveys served as the study's instruments. In order to examine the data, percentages were used, and their interpretation was based on their qualities. Based on the results of the analysis, it can be concluded that the teaching materials developed are valid, effective, and practical.
