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.

The purpose of this study was to increase students' interest in learning mathematics by using Active Knowledge Sharing learning on the subject matter of the composition of two functions and inverses of a function. This research is classroom action research (CAR). The subjects in this study were students of class XI IPA 2 Siabu High School consisting of 16 female students and 5 male students. The results of the study after using Active Knowledge Sharing learning were seen in the results of the questionnaire interest in mathematics learning for students in cycle I with an average of 60,23% while the average cycle II was 81,78%. Judging from the results of the cycle I mathematics learning test with a percentage of completeness of 38,10% while the second cycle the percentage of completeness was 85,71%. The results of the observations of student activities in the first cycle averaged 76,15% while the average cycle II was 89,80%. From the results of this study it can be concluded that using Active Knowledge Sharing learning can increase students' interest in learning mathematics in SMA 2 Siabu on the subject of the composition of two functions and the inverse of a function.

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.
