Abstract

The industrial revolution 4.0 is a formidable challenge for the world of education, one of which is learning mathematics. Moreover, in the current Covid-19 condition, which requires that learning be carried out by e-learning, the level of students' mathematical problem solving abilities is getting lower. To overcome this problem, this study applied an IT-based learning model (geogebra). The objectives of this research are to know the improvement of students' mathematical problem solving, the improvement of students' mathematical learning activities, and the improvement of the teacher's ability to manage learning. This type of research is Classroom Research. The analytical technique used is descriptive. The results of this study seen from the results of students' mathematical problem solving tests increased by 33.33%. Student activity in learning increased by 23.43%. The ability of teachers to manage learning increased by 36%. So the results of this study show that the IT-based learning model (geogebra) can improve students' mathematical problem solving, student activities in class X Multimedia I SMK Negeri 4 Padangsidimpuan.

Abstract

The low ability of creative thinking and student learning outcomes becomes the discussion of this study. To overcome this problem, in this study applied the Contextual Learning Model. the purpose of this research is useful to answer whether there is an increase in creative thinking skills between contextual learning models and conventional learning models then to find out whether there are differences in mathematics learning outcomes in a positive direction through this contextual learning model. The type of research used in this research is experimental research where the population of this study is all students of Class X Padangsidimpuan 6 High School. Data analysis using the t-test statistical test. Based on the results of the calculation of the hypothesis test the value of t count > t table or 2.007 > 1.667 (with α 0.05), so Ha is accepted and H0 is rejected. This means that there is a significant increase in creative thinking skills in the experimental class compared to in the control class.

Abstract

This study aims to determine learning outcomes using the Google Classroom and Webinar Zoom platformsduring the Covid-19 pandemic. The type of research used is experimental research. The results of this study indicate that the average pretest value of the experimental class is 18.75 and the average value of the pretest experimental class 2 is 17.50, while the posttest average value of the experimental class 1 is 40.83 and the posttest average value experimental class 2 that is equal to 48.75. Furthermore, from the results of the independent sample t-test in the equal variances assumed section, it is known that the t-count value is -1.331, which means the average value in the experimental class 1 is lower than the average value of the experimental class 2, this indicates that there are differences in learning outcomes. mathematics students who use the Google Classroom and Webinar Zoom platforms during the Covid-19 pandemic for class XI IPA students at SMA Negeri 6 Padangsidimpuan.
