Abstract

Problem-solving skills are essential in improving the creative, critical, and logical thinking skills needed in mathematics learning and daily life. This study aims to examine the effectiveness of problem-based learning (PBL)-assisted ethnomathematics-based Geocube e-module on problem-solving skills. This quantitative research applied a quasi-experimental design. The specific design applied in this research is the non-equivalent pretest-posttest control group design. The research sample consisted of 32 participants, all of whom were students involved in this study. Research instruments included test questions. The researchers analysed the data using a two-sample t-test for independent samples and an N-gain test. The results showed that the application of the PBL learning model assisted by the Geocub e-module based on ethnomathematics effectively improved problem-solving skills. It can be seen that (1) the average mathematical problem-solving skills of students in the experimental class were better than the control class, (2) there is an increase in the average of students' mathematical problem-solving skills after being taught the PBL model assisted by the Geocub e-module based on ethnomathematics. The researchers concluded that the implementation of PBL, assisted with the ethnomathematics-based Geocub e-module, effectively improved the mathematics problem-solving skills of the students.

Abstract

This research aims to develop the growth mindset of eleventh-grade students using Open Approach. Six students from grade 11 from a school under the Yala Secondary Educational Service Area Office were selected.  The students initially had a fixed mindsetat levels F1 and F2 and a weak growth mindset at level G1 before the development process. This study is a classroom action research. The instruments of this research consisted of three lesson plans on probability using Open Approach, activity sheets, a mindset assessment form, an interview form, a post-lesson report, a video camera, and a voice recorder. Data analysis was conducted using the mindset framework analysis from the Mindset Works Educator Kit (2012). Percentage analysis and qualitative methods were obtained in the research. The research findings indicated that students who participated in learning through Open Approach showed progress in their growth mindset scores, with 33% reaching level G3, 50% reaching level G2, and 17% remaining at level G1. Students showed behaviors of embracing challenges, demonstrating efforts, solving problems independently, valuing peer feedback as beneficial to learning, and viewing others' success as a source of inspiration and learning examples.
