A systematic literature review on ethnomathematics in geometry

This study aims to investigate geometrical concepts related to ethnomathematics in Indonesia. The research design used in this study is to summarize, review, and analyze 24 papers that discussed ethnomathematics. We selected either journal articles or conference proceedings that were published in the last five years, which cover documents from 2016 to 2020, and were indexed by Scopus abstract and citation database. With the assistance of the Publish or Perish tool, we were able to compile a collection of papers to complete the task. We also used PRISMA, an evidence-based minimum set of items for reporting in systematic reviews and meta-analyses, to conduct the systematic review on geometry and ethnomathematics. The process includes determining eligibility and exclusion criteria, steps in the review process (identification, screening, and eligibility), abstraction, and data analysis. The finding suggests that several ethnic groups use geometrical concepts in their cultural lives. We can find them in traditional houses, regional dances, regional specialties, batik motifs, fabrics/weaving, temples, and mosques.

Optimizing students' combinatorial-thinking skill through design-based research

The aim of this study is to construct and compose an instructional design in combinatorial learning, particularly in the concept of counting. A composed design is expected to optimize students' combinatorial-thinking skill. This research was conducted at the first author's workplace, in the topics of combinatorial and graph theory consisting of 12 students. This study consists of three phases: preliminary research, development, and assessment. In the first phase, we analyze the needs and context of learning activities, literature study, and develop a framework of thinking. In the second phase, we validates the instructional design for further improvement, classroom application, and improvement based on learning activities. In the third phase, we provide evaluation questions to students to find out the result of the application of the design related to the optimization of combinatorial-thinking. As a result, an instructional design in counting that begins with review of concept of finite sets and continues with small group discussion, class discussion, self-reflection, and evaluation.
