Data set on the Effect of Active Learning Heuristic Problem-Solving Approach on Students’ Performance and Attitude towards Mathematics

After the random assignment of eight intact classes to the treatment and comparison groups, a pretest was administered to both groups to examine students’ basic understanding of linear programming word problems. This was followed by an intervention involving a series of lessons on the application of active learning heuristic problem-solving strategies on students’ understanding of solving linear programming problems by graphical method. The entire intervention lasted for approximately three months from mid October 2020 to March 2021. At the end of the intervention, both groups of students (treatment and comparison) sat for a post-test to assess the effect of an intervention (ALHPS) for the treatment group and to compare and contrast students’ performance and attitude before and after, based on their demographic characteristics. All the test items (pretest and posttest) were scored by experts, converted into percentages, recorded in SPSS, and data were analyzed using the Statistical Package for Social Sciences (SPSS) version 26, with Hayes (2022) PROCESS macro. This provided the analysis for exploring the direct and indirect relationship between ALHPS and, students’ performance and attitude towards learning linear programming.
