Using Learning Activities on Water Resource Problems to Promote Seventh-grade Students’ Mathematical Literacy in Single Variable Linear Equations
Main Article Content
Abstract
The research aims to study problem-based learning approach to promote mathematical literacy and to study the development of mathematical literacy about linear equations in one variable using water resources-related problems. The populations were ten seventh-grade students during the second semester of the 2022 academic year. The research applied 3 spirals of classroom action research. Research instruments included lesson plans, worksheets, reflective journals, and a mathematical literacy test. The data were analyzed by content analysis and verified by data triangulation. The result indicated using problem-based learning approach to promote mathematical literacy requires teachers to begin with situations related into students’ real lives. Furthermore, the worksheet questions should be thought-provoking and be relevant to the new knowledge the students would acquire. This would support students to develop mathematical literacy in three parts, as follows formulating math problem, employing of mathematics, and interpreting and evaluating, respectively. Furthermore, teachers should clearly define their roles in group activities and the sequence of presentations and closely supervise students in each step and provide appropriate advice in a timely manner.
