Abstract

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.

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 research was conducted to determine the increase in students' creativity in learning mathematics through a learning model based on Concept Mind Mapping. This type of research is a classroom action research (PTK). The subjects in this study were students of class VII SMPN 6 Kotanopan Satu Atap. The results of the study after using Mind Mapping learning, namely the results of the first cycle test with a percentage of 41% while the second cycle the percentage of 82,35% increased by 41,35%. The results of the observation of student activity in the first cycle percentage 52,2% while the percentage of the second cycle 67,9% increased by 15,7%. And while the results of the observation of teacher activity in the first cycle the percentage was 55,45%, while the percentage of the second cycle was 81,8%, an increase of 26,35%. And it can be concluded that using a learning model based on Concept Mind Mapping can increase students' creativity in learning mathematics.
