Abstract

The purpose of this research is to improve the activity and mathematics achievement of students of class VII with learning methods of problem solving in SMP N 1 Banguntapan. Techniques of data collection in this study was done by observation, documentation, and testing. Test instrument used to test the test item, whereas the observation sheet used to determine the level of involvement of the student. Data analysis techniques for observation sheet was conducted to determine student activity, whereas for mathematics achievement tests done by calculating the average value of the class. The results showed that after the application of the learning methods of problem solving, activity and learning mathematics achievement increased. It can be shown an increase in the average yield percentage of student activity sheets based on the observation student activity first cycle 58.02%, 75% for the second cycle. While the average value of student mathematics achievement increased from an average initial value of 64,34 to 71,99 in the first cycle and second cycle being 80,83. It is expected that schools can apply the learning method.

Abstract

This study aims to determine differences in problem solving skills with the learningcycle and conventional models in Mathematics Education Programm UST. This study design is a randomized pretest-posttest control group design. The sample was a student of fourth semester. Data collected by the testing techniques that comprise the initial test (pretest) and final test (posttest). Instruments in this research is a test instrument that consists of 4 questions about the pretest and posttest 5. The trials instruments include validity, different power, test difficulty levels, and reliability testing. Data analysis techniques include equality test average, which is the prerequisite test normality and homogeneity test, and analysis of the N gain using the t test. The results showed that there are differences in problem-solving abilities with learning model and conventional learning cycle. It was seen from the significant value of the index gain = 0.000 <α = 0:05. Based on the average ability of mathematical reasoning and problem solving shows that the model Learning Cycle better than conventional models.

Abstract

The aim of this research was to describe about teaching learning process using Cooperative Team Assisted Individualization (TAI) to increase student’s active and study result to the VII B grade student’s at SMP Negeri 1 Cilacap. The hypothesis of this research was applying TAI could increase student’s active and student’s study result. This research was Classroom Action Research. The research result showed that after applying TAI in teaching learning process, the student’s active increasing. Before this research the students were passive to listen to the teacher’s explanation but after this research the students were more active to ask and discuss in group. Means student’s score increased, first 65,17 score, increasing in first cycle was 69,33 and increasing second cycle was 78,13. From the result above, it showed that TAI could increase student’s active and study result.
