Abstract

Lectures are basically a relationship between lecturers and students with the purpose of lectures being the achievement of Course Learning Outcomes. Mathematics Education students have a challenge regarding the mindset that courses in the Mathematics Education study program are not easy so that they require critical logical mathematical thinking skills. Critical thinking skills were needed because they have an impact on learning outcomes. The lecture process that is centered on lecturers is one of the causes of passive classes and low critical thinking skills of students. A learning approach was needed that could foster critical thinking skills of students. This study was aims to improve the critical thinking skills students of Mathematics Education in the Integral Calculus course through the application of Student Center Learning. The method of qualitative research is the research of classroom action, the technique of data collect is non-test, namely through observation, data sources from observation sheets and students. The research results show that there is an increase in indicators of critical thinking skills before and after the action. Before the action, students can identify problems by 15% and after the action becomes 50%. Students can analyze problems, before the action by 20% and after the action 60%. Students can solve problems, before the action 15% and after the action 65%. Students can draw conclusions before the action 25%, after the action 70%. From the research results and discussion, it could be concluded that practice the Student Center Learning could improve the critical thinking skills the students of Mathematics Education in the Integral Calculus Course

Abstract

Higher education institutions are expected to produce graduates with strong academic competencies and higher-order thinking skills. However, learning outcomes in the Discrete Mathematics course of the Informatics Study Program remain relatively low due to the abstract nature of the subject matter and the dominance of lecturer-centered instruction. This study aimed to examine the effect of an ethnomathematics-based Discovery Learning model on students’ learning outcomes in Discrete Mathematics. A quantitative approach with a quasi-experimental design was employed. The sample consisted of 40 students selected through cluster random sampling, comprising 20 students in the experimental class and 20 students in the control class. Data were collected using a learning achievement test that had met validity and reliability requirements. Data analysis was conducted through normality, homogeneity, and t-tests. The findings revealed a significant difference between the learning outcomes of students taught using the ethnomathematics-based Discovery Learning model and those taught through direct instruction (tcount = 2.614 > ttable = 1.999). The mean score of the experimental group was 71.94, which was higher than that of the control group (61.37). These findings indicate that integrating Discovery Learning with ethnomathematics effectively improves students’ learning outcomes. The study implies that culturally responsive and contextual learning approaches can serve as innovative strategies to facilitate the understanding of abstract mathematical concepts while enhancing student engagement and active participation in higher education learning environments
