Abstract

This research is a Classroom Action Research (PTK), which aims to improve the learning outcomes of mathematics through NHT type cooperative learning model in students of class VIII A MTs. Muhammadiyah conducted collaboratively between researchers and teachers of mathematics studies. In the implementation of this research, it is done by giving group worksheet and observation sheet of student activity using NHT type cooperative learning model after giving an explanation about Pythagoras Theorem material as much as two cycles that cycle I and II. After being given group worksheets then conducted the assessment includes assessment of test results of a cycle I and cycles II and group worksheet to students that is by applying learning model of cooperative learning type NHT. The subjects of this study were students of class VIII A which amounted to 20 students consisting of 15 male students and 5 female students. Techniques of collecting data in research are this observation and test. The data obtained were then analyzed. The results of the study showed that the implementation using NHT type cooperative learning model on Pythagoras Theorem material. the ability of students in solving problems on the material above has increased. With the increase of the average value of students in the first cycle was 43.45 and increased in cycle II 83.90. Improvement of student learning outcomes to mathematics learning using NHT type cooperative learning is good. This is indicated by the average value of group learning outcomes in cycle I 60.00 or being in the medium category and the average score of the learning outcomes of the group in cycle I 82.50 or in the high category. This shows the result of increased mathematics learning after conducting cooperative learning model of NHT type

Abstract

This study aimed at identifying how did the improvement in the problem-solving ability of learners work in improving the ability of learners in constructing the materials obtained after the development of Learner’s Worksheet in classroom learning. This research used Research and Development (R & D) approach using the Kemp model. Data collections were done through problem-solving tests, validation analysis, and correlation test. The indicators of this study included the effectiveness of the developed learner’s worksheet and the increased ability of problem-solving that was seen from the learning results obtained. The results showed that the average increase in the learning outcomes of the learners was equal to 79.44 with a difference in the scores of learning outcomes where tcount = 32.806 > ttable = 1.734, with a significance level of 0.000. Also, the improvement of learning outcomes on the response of learners gives significant influence with a score of 0.338 with a significance level of 0.085. Based on these results the development, the problem-solving oriented students’ worksheet is declared valid and effective based on the results of validation tests by experts and the results of the implementation of classroom learning. These results impact the students’ learning outcomes. It is expected that in the learning process with different materials, the worksheet can be applied in improving students' ability to solve problems. It is suggested for a research to collaborate the worksheet with other models and, media that can be linked to the problem-solving aspects, so that in its implementation, students have the confidence to succeed, be more active, and interested in problem-solving given
