One of the skills required in learning mathematics is numerical literacy. In learning mathematics, numeration literacy requires students to be able to solve contextual problems in everyday life. Students' literacy and numeration skills are generally low. One of the reasons is the lack of literacy training in numeration, which is usually routine issues that do not sharpen students' literacy and numeration skills. The lack of use of cultural contexts in learning and in matters also makes students more likely not to want to improve their literacy and numeration skills. This research is a developmental research aimed at developing the issue of numeration literacy based on the local wisdom of Maluku by expressing how the process of development and how the numerational literacy ability of students in solving the issue is numeration based on local Wisdom developed. The development model used is the development model by Tessmer.Tessmer's development consists of several stages: preliminary, self-evaluation, prototyping (self evaluation, one-toone, and small group) and field testing. The instrument in this research is to raise the practicality of matters and matters of numeration literacy based on local wisdom developed. The result or product of this study is eight elements of local wisdom-based numeration literacy, consisting of three True-False complex double-choice questions, one deceptive question and four descriptive questions

This study aims to determine the effectiveness of the cooperative learning type TAI (Teams Assisted Individualization) model according to the results of junior high school mathematics learning in material of set. The method used was quasi-experimental with the post-test only given to control group chosen taking design. Samples were taken using a purposive sampling technique, and two classes by considering students' initial abilities. The control class was treated by using conventional models while the experimental class uses the TAI type cooperative learning model. Data were analyzed by t-test technique. This study revealed that the learning outcomes of students who studied with the cooperative learning model type TAI (67.75) were higher compared to conventional learning models (54.45). Testing the significance of differences with the t-test shows that t count = 2.206 > t table = 2.024, meaning that there are significant differences between the two groups. It can be concluded that the TAI model is more effective as it is reflected on students' higher scores compared to those who were treated with conventional models.

The learning model has an essential role in student learning outcomes. Each learning model has different contributions, such as the Scramble learning model, which can make students think quickly, and the CORE learning model can train students to think critically. Thus, this study aims to compare students' learning outcomes with the two models, especially in arithmetic operations in algebraic forms. The research method used is quantitative research with a posttest-only group design classified as a quasi-experimental design. The research population was forty-five seventh-grade students, which were divided into two categories. The test instrument used is a description of five questions used to evaluate student learning outcomes. The study results analyzed statistically using the t-test showed that there were differences in student learning outcomes between the two groups of students. Furthermore, the continued test using Pairwise Comparison showed that students taught with the Scramble learning model had better learning outcomes than students acquainted with the CORE learning model.

Game-based learning environments, in particular, offer enjoyable learning experiences while supporting the development of conceptual understanding. This study aims to develop and evaluate Construct 2–based learning media for teaching three-dimensional geometry in Grade 7. The research employed a Research and Development (R&D) design using the Akker model. Participants included media experts, material experts, and seventh-grade students from a public junior high school in Manado. The instruments used comprised expert validation sheets, student practicality questionnaires, and learning achievement tests. The development procedure involved identifying learning challenges related to students’ difficulties in visualizing geometric solids, designing the Construct 2 media, conducting expert validation, implementing one-to-one and small-group evaluations, and conducting a classroom field test. Data were analyzed descriptively to assess the validity, practicality, and effectiveness of the developed media. The findings indicate that the learning media achieved high validity based on evaluations from both media and material experts, high practicality based on students’ responses, and high effectiveness based on learning outcomes. The dynamic visualizations, interactive quizzes, and mobile accessibility offered by the media helped students overcome common difficulties in distinguishing and visualizing geometric solids and their nets. The novelty of this study lies in demonstrating the pedagogical value of Construct 2 not only as a feasible development tool but also as an effective instructional intervention. The study offers practical implications for educators seeking effective digital media for geometry instruction and provides a foundation for further innovation in game-based mathematics learning.

Penelitian ini bertujuan mendeskripsikan strategi scaffolding yang dilakukan guru dalam pembelajaran pola bilangan bagi siswa sekolah dasar. Scaffolding dilakukan berdasarkan dua variabel yaitu (1) gaya belajar visual, auditory dan kinestetik (VAK) serta (2) argumentasi yang telah dikonstruksi siswa. Gaya belajar diselidiki melalui tes dan observasi VAK dan proses pemecahan masalah sedangkan argumentasi siswa dianalisis menggunakan komponen argumentasi Toulmin. Hasil penelitian menunjukkan bahwa strategi scaffolding berbeda dibutuhkan oleh siswa sesuai gaya belajar dan jenis argumen yang dikonstruksi. Pemelajar auditory membutuhkan strategi reviewing dan explaining; pemelajar visual membutuhkan strategi environmental provisions; pemelajar kinestetik membutuhkan strategi restructuring dan reviewing. Khusus pada pemelajar visual dan kinestetik, mereka membutuhkan multimedia sebagai scaffolding yang bermakna. Selama scaffolding argumentasi siswa berkembang dan menghasilkan peningkatan kemampuan problem solving.
