ABSTRACT
This study seeks to determine the effects of problem-solving heuristic approach on students' learning
in Logic and Set Theory. Furthermore, the study identifies the heuristic strategies used by the students; the
extent of heuristic strategies in improving students' performance in terms of motivation and interest,
knowledge acquisition, and attitude and behaviour; the effects of the heuristic approach in a student's
ability in solving Logic and Set Theory problems in terms of pre-test and post-test result; and the
significant difference between the pre-test and post-test of students under experimental groups. The study
employed a quantitative and descriptive research design wherein respondents were selected through
purposive sampling. Data was collected through pre-test and post-test from 38 BSEd Mathematics students
enrolled in the course and survey-questionnaires from 126 BSEd Mathematics students in BatStateU TNEU
ARASOF across all years.
The results were treated using scoring, weighted mean, ranking, and z-test. The study reveals that
commonly used heuristic strategies, such as systematic listing, tabulating data, careful problem reading, and
breaking down complex problems, significantly enhance students' performance in the course. These
strategies positively influence motivation, interest, knowledge acquisition, and attitude, with an overall
weighted average considered satisfactory. Additionally, experimental pre-tests yield notably better results
than post-tests, signifying a substantial impact of heuristics on problem-solving ability. Moreover,
integrating Singaporean Mathematics heuristics, including representation, simplification, generic, and
pathway heuristics specified by Sage, T. R. (2022), provide a significant mean difference between pre-test
and post-test scores, highlighting a noteworthy improvement in academic achievement before and after
instruction.
