Abstract

This study relates to the lack of optimal activity and learning outcomes of class VIII students of SMP PGRI 3 Bandar Lampung. The aim is to improve the activities and results of learning mathematics through the Numbered Head Together (NHT) learning model. The research conducted was classroom action research through 3 cycles using the NHT learning model. Based on the results of the study, there was an increase in the activities and learning outcomes of students from before the implementation of the study until after the research was conducted. The average activity of students at the time before the study was 52.31% and the percentage of completeness was 8.33%. In the first cycle the average student activity increased to 60.77% with a percentage of completeness of 66.67%. The average activity of students in cycle II increased again to 68.08% with the percentage of completeness reaching 75.00%. In the third cycle the average activity of students became 79.62% and the percentage of completeness was 83.33%. Based on these results, it can be concluded that the NHT learning model is more effectively used in an effort to improve the activity and learning outcomes of class VIII students of SMP PGRI 3 Bandar Lampung.

Abstract

The research problem is the low mathematical problem solving abilities of students. With this, the purpose of the study was to improve problem solving skills through Creative Problem Solving in the eighth grade students of the odd semester of SMP Negeri 1 Bandar Lampung. This research is a classroom action research (CAR). The research subjects were class VIIIB students of SMP Negeri 1 Bandar Lampung. The research data was taken using tests with indicators of success if 70% of students had passed the minimum completeness criteria or students had scored more than or equal to 70. From the results of the study the students' mathematical problem solving abilities in the first cycle were 60.98, in the second cycle of 70.74, and the third cycle of 77.97. Thus the completeness of students' mathematical problem solving abilities from cycle I to cycle II has increased by 9.76 and from cycle II to cycle III has increased 7.23. With this, it can be concluded that there is an increase in problem solving skills through Creative Problem Solving.

Abstract

This study aims to determine the effect of Brain Based Learning on the ability to solve mathematical problems of eighth grade students of SMP Negeri 34 Bandar Lampung Academic Year 2017/2018. Learning is carried out on two classes, one class as an experimental class in learning using the Brain Based Learning model, and one class as a control class where in the learning process applying a conventional system. Where the experimental class was sampled in class VIII H, amounting to 35 students, and the control class was class VIII G, amounting to 33 students. Hypothesis testing uses the average two similarity test (ttes). From the results of testing the hypothesis obtained thit = 4.40. From tebel t distribution at a significant level of 5% it is known thit = t (1 - ½α) = 2.00 meaning thit> tdat is 4.40> 2.00 so it can be concluded that there is an influence on the application of the Brain Based Learning learning model to the problem solving ability mathematics students, especially in class VIII SMP Negeri 34 Bandar Lampung.
