This research aims to determine and describe students' understanding of mathematical concepts through the application of the Teaching Game Team learning model. The research population was class IX students. This research uses a quasi-experimental method with a 2x3 factorial design involving 2 sample classes. Sampling used a random sampling technique with a sample of 48 students. The data collection technique uses test questions describing the ability to understand concepts in terms of students' initial abilities. Testing hypotheses 1, 2, 3 and 4 uses the t-test formula and hypothesis 5 uses the two-way Anova technique. Based on the results of the hypothesis test, it was found that hypothesis 1 was accepted, where students' overall understanding of mathematical concepts using the teaching game team learning model was better than conventional learning. Meanwhile, Hypotheses 2, 3 and 4 are rejected, meaning that the understanding of mathematical concepts for those with high, medium and low initial abilities using the teaching game team learning model is no better.or equal to conventional learning. Hypothesis 5 is rejected, so there is no interaction between the teaching game team learning model in terms of initial ability to influence understanding of mathematical concepts.

This research was motivated by the students' low mathematics problem-solving abilities. There are 5 five indicators of 9 mathematical problem solving abilities that students have not been able to achieve. One of the reasons is that there are still many students who are not active in the learning process and there is a lack of variety in the learning strategies used by teachers. This research aims to describe mathematical problem solving abilities using a Problem Based Learning model based on ethnomathematics compared to conventional learning for class IX students at MTs N01 Merangin Year 3 Lesson 2023/2024. The method used in this research uses an experimental method and the population is all students in class IX MTs N 1 Merangind for the 2023/2024 academic year, totaling 182 people. The sampling technique uses Simple Random Sampling. The samples selected were Class IX C as = Experimental Class and Class 5 IX D as Control Class. The method for analyzing data before conducting a hypothesis test is tested first with a normality test and a harmony test, where it is known that the data is normally distributed and has homogeneous variance, so the hypothesis is tested with the t-test. The average score obtained from data analysis for the experimental class was 53.68, variance 39.0250, while the control class obtained an average score of 49.10, variance 68.1780. The results of the hypothesis test were obtained, tcount = 2.373 and ttable = 1.671. Because tcount > ttable, H0 was rejected and H1 was accepted. The conclusion of this research is that the ability to solve mathematical problems using the Ethnomathematics-based Problem Based Learning model is better than using conventional learning for class IX students at MTs N 1 Merangin for the 2023/20 academic year

Pendidikan STEM (Sains, Teknologi, Teknik, dan Matematika) menjadi fokus utama dalam banyak negara karena dianggap sebagai kunci untuk menghasilkan generasi yang mampu mengatasi tantangan global yang semakin kompleks. Pencapaian dalam pembelajaran STEM dipengaruhi oleh berbagai faktor, baik eksternal seperti kurikulum dan metode pengajaran, maupun faktor internal, terutama inteligensi dan bakat individu. Penelitian ini bertujuan untuk mengeksplorasi dampak perbedaan individu dalam hal inteligensi dan bakat terhadap pencapaian pembelajaran STEM. Berdasarkan tinjauan teori dan penelitian sebelumnya, inteligensi yang lebih tinggi dan bakat alami di bidang STEM berperan penting dalam kemampuan siswa untuk menyerap informasi, berinovasi, serta memecahkan masalah yang kompleks. Penelitian ini diterapkan pendekatan kualitatif deskriptif, dengan fokus pada kajian literatur yang relevan untuk menggali hubungan antara inteligensi, bakat, dan pencapaian dalam pembelajaran STEM. Hasil penelitian menunjukkan bahwa baik inteligensi maupun bakat, bila dikembangkan dengan baik, dapat mempercepat proses pembelajaran dan meningkatkan pencapaian dalam bidang STEM. Temuan ini memberikan wawasan untuk merancang pendekatan pengajaran yang lebih inklusif dan disesuaikan dengan perbedaan individu dalam pendidikan STEM.
