Abstract

The purpose of this study was to improve liveliness and mathematics achievement in cooperative students of class VII A SMP Muhammadiyah Salam Magelang with cooperative learning TPS (Think Pair Share). This research is Classroom Action Research (CAR). The subjects in this study were students of class VII A which is 15 students who comprised 10 male students and 5 female students. Research findings indicate that the liveliness and increase math achievement. This can be shown by an increase in the average yield percentage of student learning liveliness based on the observation sheet for each cycle is the first cycle of student liveliness and 63.33% for the second cycle was 88.83%. While the average value interpretation of students' mathematics learning increased from an average initial value of the average of 46.33 to 55.67 in the first cycle and the second cycle to 84,67.

Abstract

The purposes of this research was to describe the motivation and achievement of mathematics in VIII A grade of SMP N 1 Pleret Bantul using Numbered Heads Together (NHT). This research is Class Action Research (CAR). The technique of data done by observation, questionnaire, tests and documentation. The results of research that the motivation and achievement of mathematics is increased. Achievement of the KKM also increased. Based the results of the research, Numbered Heads Together (NHT) can increase motivation and achievement of mathematics. So, teachers can implement Numbered Heads Together (NHT) as a variation of learning.

Abstract

The purpose of this research is to improve the ability to think creatively and mathematics achievement of tenth grade students of Engineering Computer Networking SMK Negeri 3 Yogyakarta with models of learning in group problem posing. This research is a classroom action research (CAR) conducted in two cycles. The subjects were students of tenth grade Engineering Computer Networking, amounting to 36 students. Data collection techniques in this study using observation, testing, interviews and documentation. Results of this study after using problem posing learning model showed an increase in the ability to think creatively and math achievement of students. (1) The mean score of students' creative thinking abilities increase of 61.46% on the pretest to 80.55% in the first cycle test and increased again to 87.5% in the second cycle. Criteria for each aspect of the ability to think creatively in the second cycle varies. Aspects smooth on very high criteria. Aspects of high flexibility in the criteria. Aspects of the criteria are originality. Aspects of detail on very high criteria. (2) There is an increase in the percentage of student mastery of 75% of all students achieving ≥ 75 KKM. It is evident from the increase in 44.44% (16 students completed) on the pretest increased to 58.33% (21 students completed) in the first cycle test and increased to 77.78% (28 students completed) I. Model of learning in group problem posing able to be an alternative learning models improve the ability to think creatively and mathematics achievement.
