Tujuan penelitian yang dilakukan adalah menganalisis tingkat kemampuan siswa melalui penerapan asesmen diagnostik kognitif pada mata pelajaran matematika. Matematika masih menjadi momok bagi sebagian besar siswa termasuk di SD Kanisius Duwet. Padahal matematika memiliki banyak kegunaan bagi pengembangan ilmu pengetahuan lainnya. Oleh karena itu guru harus mampu merancang pembelajaran matematika yang menarik dan menyenangkan sesuai dengan karakteristik siswa melalui hasil analisis tingkat kemampuan siswa pada asesmen diagnostik kognitif. Penelitian ini menggunakan metode eksperimen dengan pendekatan kuantitatif. Teknik pengumpulan data yang digunakan adalah angket, dan wawancara. Subjek penelitian adalah siswa kelas VI A dengan jumlah 30 siswa. Analisis data dilakukan melalui reduksi data, penyajian data dan penarikan kesimpulan. Hasil analisis perencanaan diperoleh data bahwa siswa kelas VI A SD Kanisius Duwet memiliki tingkat kemampuan yang berbeda-beda dibuktikan dengan hasil analisis diperoleh 20% siswa berada pada tingkat kemampuan tinggi 33,3% siswa dengan tingkat kemampuan sedang, dan 46,6% siswa yang berada pada tingkat kemampuan rendah.

This study aims to determine whether PPR learning can improve numeracy literacy in the concept of numbers in students. This type of research was descriptive qualitative research with a sample of 24 Elementary School Teacher Study Program students. Pretest and posttest are used to find out whether there is an increase in student knowledge, and observation is used to find out the implementation of lectures with PPR dynamics. The results of this study indicate that: (1) students attend lectures with PPR dynamics; (2) numeracy literacy in the number concept of students. The results of the study showed that there was an increase in numeracy literacy in the number concept of students by 28%.

Online learning is growing along with the development of today's technology. Online learning development will improve the quality of the learning process. The research goal is to improve an online learning portal based on Artificial Intelligence (AI) within the Team-Based Learning (TBL) framework. The benefits of AI in personalizing learning based on how students learn, and even the TBL usage as a learning method, are explored to improve student learning results. The method used in this research is a method for conducting research development. MOODLE as a Learning Management System is being used to expand the online learning portal. In addition, AI technology is developing using algorithms based on collaborative filtering to predict learning styles and evolutionary algorithms to analyze student group growth. There were 262 students from ten elementary schools (SD) in three provinces who participated in this study. The application of the R data analysis program used paired t-test to compare the pre-test and post-test. The findings of this study indicate that AI-based online learning within the TBL framework can significantly improve student learning outcomes.
