Abstract

According to Van Hiele, in understanding geometry, students need to understand five stages, namely stage 1 (introduction stage), stage 2 (analysis stage), stage 3 (sequencing stage), stage 4 (deduction stage), and stage 5 (accuracy stage). Each student has different geometric thinking abilities. This study aims to examine the geometric abilities of junior high school students in the material of flat-sided geometry according to Van Hiele's Theory. This research belongs to the type of qualitative research with a case study design. It was conducted at three schools in Padang, West Sumatra, Indonesia. The subjects were students of SMP Negeri 1 Padang, SMP Negeri 7 Padang, and SMP Negeri 25 Padang. Data collection was carried out using tests, interviews, and documentation. Data analysis was carried out with the stages of data reduction, data presentation, and data verification or drawing conclusions. The data originality technique was carried out with the triangulation technique, where the researcher compared the test data with the results of interviews with students. Of the 94 students (male = 38, female 56) tested based on the geometric thinking level of Van Hiele Theory, 92.55% of the students reached the Van Hiele thinking stage at the visualization level. As many as 45.74% of students reached the level of geometric analysis, and 6.38% of students reached the level of abstraction. For the level of deduction and accuracy, no one has been able to solve the problem. The results obtained in this study are that most students are still at stages 1 and 2, unlike van Hiele's opinion, which revealed that the level of geometric thinking for junior high school students is at level 3. According to the study results, it is essential to carry out further checks on the level of geometric thinking of junior high school students in other areas.

Abstract

Taiwan's rapid development in education is evidenced by its high ranking in the 2022 PISA assessment, making it an attractive destination for international students. National Dong Hwa University, particularly its Department of Computer Science and Information Engineering (CSIE), has become popular among these students. This study focuses on the impact of integrating local and international students in calculus courses, a required subject, due to the close relationship between mathematics and computer science. The study sampled 14 international and 14 local first-year students, collecting data through questionnaires to assess their self-confidence, communication skills, and motivation. At the same time, academic performance was measured through midterm exam scores. The findings revealed significant differences in academic performance, self-confidence, and communication between local and international students, with p-values of .024*, .016*, and .012*, respectively. Among international students, self-confidence and communication were significantly correlated with academic performance (p=.013* and p=.026*), while for local students, a significant relationship was found between scores and communication (p=.035*).
