Abstract

Understanding the concept of flat building is one of the basic competencies that is very important in learning mathematics in elementary school because it is the foundation for geometry material at the next level, but unfortunately, many students still have difficulty in recognizing, distinguishing, and understanding the properties of various forms of flat building thoroughly. These difficulties are often caused by learning approaches that are too abstract, lack of use of concrete media, and lack of active involvement of students in the meaningful learning process. This research aims to design a didactic design that facilitates the understanding of the concept of flat building through the use of concrete objects. The research method used is didactic design research with a qualitative approach. The research subjects consisted of grade IV elementary school students. Data was collected through observation, interviews, and documentation of student learning outcomes. The results of the study show that the use of concrete objects such as geometrically shaped pieces of paper, and everyday objects is able to help students understand the characteristics of building flat visually and tactily. The didactic design developed contains three stages, namely the stage of initial didactic situation analysis (prospective analysis), the stage of implementing didactic design in the classroom (metapedagogical), and the stage of retrospective analysis. These findings suggest that concrete object-based learning is effective in improving conceptual understanding and reducing students' misconceptions about flat builds. The implications of this research can be used as a reference for teachers in designing meaningful and contextual mathematics learning.

Abstract

Understanding flat shapes remains a challenge for elementary school students, mainly due to the abstract and contextual nature of the material presented. This study aims to develop and evaluate a didactic design for teaching flat shapes by integrating Sumba ikat woven fabric geometric motifs as a contextual medium. The method used was Didactical Design Research (DDR) with stages of design, limited testing, and revision. The research was conducted at SDIT Fadhilah Pekanbaru, involving 30 fourth-grade students as respondents. The instruments used included concept comprehension tests, student worksheets with woven motifs, observations, and semi-structured interviews. The pre-test results showed that around 65% of students had misconceptions about basic geometric shapes. After the intervention, the post-test scores increased by an average of 20%. In addition, interviews showed that the woven motifs made it easier for students to recognize flat shapes that were previously difficult to distinguish. This study concludes that the integration of Sumba ikat weaving geometric motifs into didactic design not only improves cognitive understanding but also encourages affective engagement and appreciation of local culture. This model is relevant to be applied in the context of the Merdeka Curriculum, which emphasizes context-based learning and cultural values.

Abstract

This study aims to design and analyze a didactical design in mathematics for introducing plane shapes to elementary school students using traditional cakes as learning media, namely onde-onde, lemper, and kue lapis. The method employed is Didactical Design Research (DDR), which consists of three stages: initial didactical situation analysis, metapedadidactical analysis, and retrospective analysis. Through observation and interviews, it was found that concrete media based on local culture can enhance students’ understanding of geometric shape concepts. The didactical interaction between teacher, students, and learning materials became more active and meaningful. This design demonstrates that a contextual approach is not only effective in delivering mathematical content, but also supports cultural preservation and strengthens students’ learning motivation.
