The research aims are to determine the improvement of students' critical thinking skills in mathematics by using the STAD Cooperative learning model. The type of research is Classroom Action Research (CAR), which consists of 2 cycles. The subjects of this research are class VIII-4 of SMP Negeri 4 Padangsidimpuan, totalling 27 people. The object of this research is the Student Team Achievement Division (STAD) learning model to improve students' critical thinking skills. The results showed that the student learning tests by applying the STAD Type Cooperative learning model in the first cycle has obtained with a minimal category of 70.93% and in the second cycle increased to 86.04%. The increase from the period I to period II was 15.11%. With the achievement, the indicator has achieved by ≥ 80%. Then the results of the observations of student activities in the first cycle obtained levels of student activity of 71.97% "Enough" in the second cycle 85.24% with "Good" criteria. The increase that occurred period I to period II was 13.27%. Achievement indicator has accepted ≥ 80%. For the results of the observations the ability of teachers in the first cycle and second cycle obtained by the category of "Good".

The type of research used is Classroom Action Research where the research is carried out by lecturers in their own class by implementing, implementing, and reflecting on collaborative and participatory actions with the aim of improving performance as a lecturer so that learning outcomes increase. The subjects of this research were students of the 6th semester of the Mathematics Education study program in the Elementary Linear Algebra course which consisted of 20 students. Meanwhile, the object of research is the improvement of students 'abilities in mathematical problems, increasing students' self-confidence and the ability of lecturers to learn through the Inquiry method. The conclusions that can be drawn from this study are 1) The ability of student learning outcomes in mathematics learning through the inquiry method in Elementary Linear Algebra is shown by the proportion of learning test results, namely 78.50% with the category "Enough" in the first cycle increased to 86.84% category "Good" in cycle II. 2) The ability of students' self-confidence using the observation method has increased when viewed from the student results in the first cycle with the proportion of 84.45% in the "Good" category, the proportion of observations of students in the second cycle becomes 94.57% in the "Very Good" category.

E-learning-based interactive mathematics teaching materials are a means of learning mathematics that can be used by educators to assist students in the learning process using electronics such as mobile phones and computers. The teaching materials also help educators and students learn outside of school and at a distance. The research method used is Research and Development (R&D) based on the 4D research and development model. The stages carried out are the defining stage, the planning stage (design), the development stage (develop), and the dissemination stage (disseminate). The results of the validation of teaching materials obtained on the feasibility aspect of the content are 3.58, the linguistic aspect is 3.67 and for the presentation feasibility aspect is 3.53. Student learning outcomes come from the pre-test and post-test scores. The average score of students in the pre-test activity was 40.25, while the post-test was 82.19.

This study aims to determine whether there is a positive and significant effect between the Group Investigation learning model on students' mathematical reasoning abilities in the Pythagorean Theorem subject in class VIII-B MTS YPKS Padangsidimpuan. The population in this study were all eighth grade students at MTS YPKS Padangsidimpuan. The sample of this study consisted of 2 classes of 30 students, namely class VIII-B as the experimental class and class VIII-A as the control class. The experimental class uses the Group Investigation learning model, and the control class uses the Conventional learning model. This type of research is an experiment by giving treatment to the research sample group and then given a pretest and posttest, as a data collection tool. Before testing the hypothesis, first the normality and homogeneity of the test were tested. From the post-test data analysis of reasoning ability using the t-test at level = 0.05, it was obtained that thitung > ttabel was 10.322 > 1.667 so that for both hypothesis tests H0 was rejected and H1 was accepted. It can be concluded that there is a positive and significant influence between the Group Investigation learning model on students' mathematical reasoning abilities.
