This study aims to describe the effectiveness of the STAD problem-based learning setting in terms of learning outcomes and mathematical dispositions. This research is an experimental research type of pre-experimental. This pre-experimental study used a one-group pretest-posttest design with a population of students in the second semester of the Mathematics Education Study Program at the University of Flores for the 2020/2021 academic year. The sample in this study was a class of second-semester students. The research instrument used was a test of learning outcomes in the form of a description of 6 questions and a non-test in the form of a mathematical disposition questionnaire in the form of a Likert scale with five answer choices. The data analysis technique used was the paired-sample t-test with the help of SPSS Windows Version 16. Based on the test results, obtained the value of sig. of 0.00 for learning outcomes and mathematical dispositions. This result shows that the problem-based learning setting of STAD is effective and good to be applied in the design of the learning process in a number theory course, in terms of learning outcomes and mathematical disposition abilities.

Penelitian ini bertujuan untuk mendeskripsikan keefektifan Problem Based Learning (PBL) dengan penggunaan bahan manipulatif ditinjau dari minat belajar siswa. Penelitian kuasi eksperimen ini menggunakan pendekatan kuantitatif dengan dua perlakuan yaitu untuk kelas eksperimen berupa pembelajaran problem based learning dengan penggunaan bahan manipulatif dan kelas kontrol menggunakan pembelajaran problem based learning. Pengumpulan data dilakukan dengan menggunakan angket untuk mengetahui minat belajar siswa terhadap pembelajaran matematika. Untuk melihat keefektifan perlakuan pada kedua kelas, data minat belajar matematika masing-masing dianalisis dengan uji t satu sampel. Perbedaan keadaan siswa sebelum perlakuan dan perbedaan keefektifan diukur dengan menggunakan MANOVA. Selanjutnya untuk membandingkan keunggulan antara kelas eksperimen dan kelas kontrol digunakan uji t dua sampel independen dengan taraf signifikansi 5%. Hasil penelitian menunjukkan baik pembelajaran problem based learning dengan penggunaan bahan manipulatif dan pembelajaran problem based learning, keduanya efektif ditinjau dari minat belajar siswa terhadap pembelajaran matematika. Terdapat perbedaan keefektifan antara kedua kelas setelah diberikan perlakuan, dimana kelas dengan pembelajaran problem based learning dengan penggunaan bahan manipulatif lebih efektif ditinjau dari minat belajar siswa terhadap matematika.

The impact of the COVID-19 pandemic is not only on the safety aspect of people's lives but also on the education aspect. One of the problems faced is that students have problems understanding each material given by the teacher because what has experienced so far is that students only get assignments online (What's App, E-Learning), then students do the assignments and send them back. At that moment, there is no direct explanation from the teacher, and each student's answer only relies on the internet (google), even though students need an understanding of the concepts in the material provided, especially mathematics for fractions. One of the activities that help students develop themselves in improving their learning abilities is the tutor. Solution offered to students who live in RT 003, Paupire Village, in this service activity is to provide Student learning assistance and guidance by using fractional block teaching aids during the Covid 19 Pandemic to increase understanding of concepts and learning outcomes. Tutoring can increase students' motivation and academic value, increase understanding of fraction concepts and learning outcomes.
