This study aims to produce a scientific-based elementary school mathematics learning module for students of the PGSD study program at PGRI Silampari University that is valid, practical and has potential effects. The research method used is development research with a 4D development model, consisting of the stages of Define, Design, Development and Disseminate. The instruments used to answer the research objectives are the validation questionnaire, practicality questionnaire, and Test. The data in this study were analyzed using the Aiken V and N-Gain formulas. development of a scientific-based elementary school mathematics learning development module in semester V of the PGSD Study Program at PGRI Silampari University, so it was concluded that from the three validators, namely language experts, material experts and media experts, an overall value of 0.91 was obtained. For the practicality test stage of lecturers and students with an overall percentage of 93.18. While for the effectiveness test stage after being analyzed by the researcher, a percentage value of 0.52 was obtained, therefore the scientific-based elementary school mathematics learning development module is feasible to use.

Technology has rapidly developed across various fields, including education, which has been significantly impacted by technological advancements. The development of computer technology can be utilized to assist in creating effective learning media. This research aims to develop web-based interactive learning media using an ethnomathematics approach for teaching flat-sided space shapes to eighth-grade junior high school students. The development model employed in this study is the 4-D or 4-P model, which was modified into three stages: the definition stage (define), the design stage (design), and the development stage (develop). The research subjects consisted of 15 students from SMP Swasta Budi Agung Medan. The instruments used in this research included expert material assessment questionnaires, expert media assessment questionnaires, and student response questionnaires. The findings revealed that the developed web-based interactive learning media with an ethnomathematics approach received a score of 93% from expert media validators, indicating that the media is highly valid. Expert material validators gave a score of 87%, classifying it as very good or highly valid. Meanwhile, the student response assessment showed an average score of 86%, indicating that the media was highly engaging and met the required criteria.

UNDERSTANDING BY DESIGN: MENGGUNAKAN SEBAGAI KURIKULUM ALUR MUNDUR UNTUK PEMBELAJARAN MATEMATIKA DI INDONESIA

This study aims to look at the the concept and application of understanding by design as a backward design curriculum for mathematics learning in Indonesia. The articles used as the core review source for this research were 5 articles that had a reputation of SINTA standards. From the results of the review, it was found the understanding, role and steps of UbD as an integral part of learning in Indonesia today. In mathematics learning, which is often a problem for students, the problem can be overcome by creating effective and interesting learning through learning with the UbD framework. Of course, the teacher's role as designer and facilitator has had a big influence, even though UbD is given the freedom to determine the direction of the material, this does not mean that the teacher underestimates the characteristics of students as well as their learning styles and interests. The conclusion of this research is to show the main focus in the understanding by design approach, namely emphasizing the desired results (learning objectives).

ANALISIS MOTIVASI BELAJAR SISWA DALAM PEMBELAJARAN BANGUN RUANG KELAS VI MENGGUNAKAN MODEL PROBLEM BASED LEARNING

The knowledge that is always being developed is knowledge about mathematics. Mathematics is a science that can train a person's thinking and logical abilities. Apart from that, research also focuses on other research in everyday life, especially the science of problem solving. Mathematics education is about connecting, designing, and creative learning. Sometimes studying mathematics in class can feel scary compared to other subjects, especially when it involves shapes. Abstract shapes have three-dimensional geometric concepts such as cubes, blocks, pyramids, prisms, cylinders and balls which are not easily understood with explanations or two-dimensional drawings. To overcome this problem, teachers should use teaching methods that increase students' conceptual understanding and make learning problem-based (PBL). The subject of this research is class VI of SD IT Uswatun Hasanah Padang Jaya. There are 29 students. The results of the research showed that 82.86% of students felt happy, so it was concluded that the use of PBL in mathematics education made students motivated in learning, especially class VI Bilal SD IT Uswatun Hasanah Padang Jaya.
