Abstract

Integral calculus is an important course, but it often becomes a problematic phenomenon for students, even in collaborative learning settings. Various types of research have been conducted to examine this phenomenon, one of which is phenomenology. The purpose of this study is to analyze the experiences of students in collaborative integral calculus courses. The study involved two program chairs, two lecturers, and nineteen prospective mathematics teachers from programs in Indramayu and Mataram, Indonesia. The main instrument in this study was the researcher, supported by additional tools such as program observation sheets, lecturer interview guides, and student questionnaires. The research data were analyzed using thematic analysis. The findings revealed several challenges in the course, such as students' lack of readiness for online learning and visualization, the short duration of discussion videos that were not yet linked to real-world contexts, and unstable internet connections. Although the outcomes of collaborative learning have not surpassed those of conventional methods, there are several advantages, such as students being able to replay discussion videos and gain new peers. This study recommends that collaborative learning should utilize virtual reality based on ethnomathematics, increase the number of discussion videos, and strengthen students' prerequisite knowledge to better meet the needs in integral calculus courses.

Abstract

The research aimed to optimize students’ mathematical solving abilities through the implementation of a didactic design developed based on lesson study activities on triangular number patterns. The research design used was didactical design research. Participants in the study were 10 students (12–15 years old) at a junior high school in Mataram, Indonesia. The researcher was the main instrument, with several additional instruments, one of which was the didactic hypothesis design. The data were analyzed using qualitative analysis. The research results revealed an increase in students’ mathematical problem-solving abilities during the implementation of didactic design on triangular number pattern material. However, the increase that occurred was less than optimal. This increase resulted from the didactic design encouraging students to use Quizizz, geoboards, and inspirational videos to solve problems. However, when watching inspirational videos and Quizizz, there were problems, such as an unstable internet connection, so activities that should have been done in groups were done collectively for one class.

Abstract

Conversion of mixed numbers into improper fractions was one of the challenging formulaic issues in fraction learning that posed problems in education. However, there were not many studies investigating this conversion. Furthermore, few studies have attempted to provide solutions regarding this conversion issue. Therefore, this study aimed to identify the learning constraints students experienced when converting mixed numbers into improper fractions and offer alternative solutions to minimize these learning obstacles. The research design used to achieve this goal was didactical design research (DDR). DDR was chosen as it employed the identified learning constraints to develop didactic designs in fraction learning. Participants in this study were mathematics teachers aged 26, with less than five years of teaching experience. The primary instrument in this research was the researcher, using several supplementary tools such as a fraction comprehension test, interview guidelines, and didactic designs. Data were subsequently analyzed using qualitative data analysis. The research findings revealed that students were indicated to encounter learning obstacles of an epistemological nature, as they seldom initiated learning with real-life problems. The proposed solution in the didactic design was using problems as initial situations in learning, which would then be responded to by students in the form of didactic conditions. The recommendation offered in this study is implementing the didactic design itself.
