Effectiveness of Laps-Heuristic Learning With An Open-Ended Approach on Critical Thinking Ability

The objective of this study is to assess the efficacy of LAPS-Heuristic learning, coupled
with an Open-Ended instructional approach, in enhancing the critical thinking skills of seventh-grade
students in a middle school setting. The research employs an experimental methodology with a
quantitative framework, specifically utilizing a posttest-only control group design. The study participants
consist of seventh-grade students from classes VII A and VII C at SMP MTs Muhammadiyah 1
Malang during the 2022/2023 academic year. Data collection is achieved through a written critical
thinking skills assessment. Analysis of the critical thinking ability test results is conducted using the
Independent Sample T-test. The findings reveal significant disparities in the critical thinking abilities
of seventh-grade students between the experimental group utilizing LAPS-Heuristic learning with an
Open-Ended approach and the control group employing conventional teaching methods. Thus, it can
be concluded that LAPS-Heuristic learning, when combined with an Open-Ended approach, proves
to be an effective strategy for enhancing students’ critical thinking skills.
