Abstract

The purpose of this research is to find out the increase of student’s mathematical problem solving competence through the implementation of Osborn Learning Model, as well as compare it with the student who earned conventional learning. In addition, the purpose of this research is to find out the increase of mathematical problem solving competence on a group of student with high, middle, and low capability. The next purpose is to find out the attitude of the students against the osborn learning model. Methods used in this research is quasi Experimenter Method with pretest and post-test Marginalized Control Design. Population on this research are all of students of VIII grades in SMPN 1 Bandung. Samples on this research are two classes of VIII grades, one class as Experimental Class and the other one as control class. Research data obtained through the test of student’s mathematical problem solving competence, questionnaire, and observation sheets. The result of this research shows that the increasing of student’s mathematical problem solving competence with Osborn Learning Model better than the increasing of student’s mathematical problem solving competence with conventional learning. There are differences in the increasing competence on the groups of high capability, middle capability and low capability in osborn class and conventional class. In general, the students give a positive attitude against Osborn Learning Model.

Abstract

artifacts, and so on. However, there still needs to be more emphasis on the connection between traditional boat building and mathematics. Therefore, this article aims to characterize the ethnomathematics connections built from the traditional Indramayu boat shape. Theoretically, this research is based on ethnomathematics, ethnomathematics connections, and Universal Activity. The research approach used is qualitative by using an ethnographic design. This article's research object is the form of traditional boats in Indramayu—the research data obtained from preliminary studies, observations, interviews, and documentation. Interviews were conducted with three people, namely two builders and crew members (Ship's Crew). Based on the results of the study, it was found that the ethnomathematics connection to traditional boats can be seen in the forms of boat buildings and the accessories that complement them, such as the lunas, haluan, lambung, kemudi, hatch, and storage area. Institutionalizing the parts of the boat can represent the concepts of plane and spatial geometry. Therefore, the implications of this article can enrich students' starting points for learning mathematics and facilitate students' understanding of abstract mathematics using the context of society's culture.

Abstract

The aim of the research was to develop a collaborative online learning design for integral calculus courses through lesson study activities. The study employed didactical design research as the research design. Participants in the research consisted of 19 students (aged 19–22 years, 18 women) from two private universities in Indonesia. The researcher served as the main instrument in the study, utilizing several additional instruments, such as collaborative online learning design, presentation slides, and documentation studies. The data were analyzed using qualitative data analysis. The research revealed that collaborative online learning design through lesson study activities helped prospective mathematics teachers understand concepts related to integral calculus, especially definite integrals and the substitution method. This was because the collaborative online learning design used learning videos as a means for students to understand the concept of integral calculus. Apart from that, the collaborative online learning design also facilitated students’ understanding of this concept more deeply.
