Abstract

The problem in this study is the students' low self-confidence. To increase students' self-confidence in mathematics lessons on set material with peer tutoring strategies. The results of students' mathematics tests using the Peer Tutoring strategy in class VII A MTs Muhammadiyah 22 Padangsidimpuan were proven by the results of the mathematics test of students in cycle I obtained an average of 51.42% and in cycle II 82.85% the average increase from cycle I to cycle II was 31.43%. Based on observations of teacher performance, there was an increase in the cycle where I obtained an average value of 58.50%, cycle II obtained an average value of 88.00%, an average increase of 29.50%. Based on observations, teacher activity also increased where the first cycle obtained an average of 64.55% and the second cycle was 81.55% and an increase in the average value of 17.00%. Based on the research results, it can be denied that using the Peer Tutoring strategy can increase student self-confidence and teacher performance in class VII A MTs Muhammadiyah 22 Padangsidimpuan.

Abstract

AbstractThis study aims to determine: the influence of students' mathematical critical thinking analysis in solving mathematical problems through the reward and punishment method in SMA Negeri 1 Batang Angkola. The type of research used is quasi-experiment with pre-test-post-test control group design. The population in this study consisted of all class X students of SMA Negeri 1 Batang Angkola, while the sample consisted of 20 students in class X-1 as an experimental class and 20 students in class X-2 as a control class. Sampling is done through purpose sampling technique. The research instrument used was a test of students' mathematical critical thinking skills. Statistical hypothesis testing in this study used the t test. The effect of the ability of mathematical critical thinking students who get learning with reward and punishment learning is higher than students who get regular learning. With the results of the calculation obtained, then t count = 1.85 and at the level of α = 0.05 and dk = 20 + 20 - 2 = 38 then obtained t table = 1.54. Thus it is concluded that tcount> t table or 1.85> 1.54, so Ha is accepted and H0 is rejected. This shows that students' critical mathematical thinking is good enough. With reward and punishment learning makes students more active, enthusiastic and independent. This means that the influence of critical thinking in mathematics mathematics learning of students towards reward and punishment learning is better than students' critical thinking of mathematics by using ordinary learning in class X of SMA Negeri 1 Batang Angkola. Keywords: Critical Thinking, Reward and Punishment, Mathematical Problems
