Abstract

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.

Abstract

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.

Abstract

This thesis discussed the effect of independent learning on mathematics learning outcomes in grade VII SMP Negeri 2 Tano Tombangan Angkola. This research is a quantitative research method of non- experimental variabel studied, namely student X learning independence and Y mathematics learning outcomes. The purpose of this study was to determine the effect of independent learning (X) on mathematics learning outcomes (Y) of student at SMP Negeri 2 Tano Tombangan Angkola. The sampel used was 30 students, while data collection was carried out by means of a questionnaire and essay test for students with the subject of the set Based on the t-test analysis thitung of 11.49 and the ttabel value is 2,048. Means thitung is greathes than ttabel (11,49 > 2,048) this means that reject Ho accept H1 or there is a sigmificant direct influence between independent learning on mathematics learning outcomes of VII grade student of SMP Negeri 2 Tano Tombangan Angkola with a coefficient of determination of 82,7% the remaining 17,3 % is influenced by other factors not examined.
