Abstract

One of the professional competences of mathematics teacher is the ability of mathematical problem solving. At high school level, the increase of this ability is influenced by creativity. It means, that if the students’ creativity is getting higher, their ability of mathematical problem solving is also progressively better, conversely. The applying of  Treffinger’s model in mathematics teaching and learning at high school, have been proven can develop the students’ creativity. In this research, Treffinger’s model is applied to  students prepared for being mathematics teacher as a mean to improve their ability of  mathematical problem solving. The sampels consist of 32 students of Mathematics Educational Department, taken by purposive sampling. The data collecting uses instrument in the form of test about the ability of mathematical problem solving. The result of this research indicates that the applying of  Treffinger’s model is significant influencing the increase of the mathematical problem solving’s ability. It is caused by the fact that the students have their own variation, creativity, and experience so that can be developed swiftly in mathematical problem solving.

Abstract

the purpose of this research is to improve students' motivation and learning outcomes in mathematics through cooperative learning Team Assisted Individualization (TAI ) in class VIIIC SMP Kalibawang Kulon Progo . This research is Classroom Action Research (CAR) conducted in two cycles . The subjects of this study were grade students of SMP Negeri 2 Kalibawang VIIIC Kulon Progo by 23 students. Object of this study is to learn and motivation to learn mathematics. Data collection techniques in this study used observation, questionnaires, tests and documentation . The results showed that after an application using cooperative learning Team Assisted Individualization (TAI) in the class of SMP N 2 Kalibawang VIIIC Kulon Progo, motivation and learning mathematics increased student learning . This is indicated by the percentage increase in the motivation to learn an average score of 69.91 % in the pre-action , while improving on the first cycle with an average percentage of 71.77%. Increase of 77.64 % in the second cycle . The results of students' mathematics learning is also increasing. In early tests the ability of 52.71. In the first cycle, the average yield increased to 58.55. In the second cycle the average yield increased to 76.36. The results showed that motivation and learning of mathematics increases. Based on the results of the research, the math teacher can apply Team Assisted Individualization (TAI) variations in mathematical learning model.

Abstract

The research purposes to increases motivation and mathematics achievement with Survey, Question, Read, Recite and Review (SQ3R) learning methods in class VIIB SMP Taman Dewasa Ibu Pawiyatan Yogyakarta. Type Classroom Action Research. The research subjects were students of class VIIB SMP Taman Dewasa Ibu Pawiyatan Yogyakarta Jetis and object of this research were motivation and mathematics achievement. Techniques of data collection is using observation, questionnaire, tests, and documentation. The results showed that motivation and mathematics achievement increase. The results can be seen from motivation observation pre-term by 20.83% with low category, increased to 40.83% with the moderate category in first term. Then increased again to 66.31% in second term with the high category. The results can be seen from motivation questionnaire pre-term by 56.82% with moderate category, increased to 62.4% with the high category in first term. Then increased again to 72% in second term with the high category. The results of mathematics achievement obtained from test, with percentage completeness obtained pre-term 22.2% with an average of 59.3. In first term increased to 57.14% with an average of 66.5 and in second term increased to 78.57% with average value of 71.57.

Abstract

The purpose of this study is to determine the three models of the effect of learning on mathematics achievement. To determine the effect of motivation on mathematics achievement. To determine the interaction between the model of learning and motivation on mathematics achievement. F test group gained Ftab Fhit = 41,687 and df 1; 57 at 5% significance level is 4,02. Fhit> Ftab learning model means that there are influences on mathematics achievement. F test derived motivation Ftab Fhit = 0,909 and df 2; 57 at 5% significance level was 3,17. Fhit <Ftab means there is no effect of motivation on mathematics achievement. F test obtained Ftab Fhit interaction = 0,650 and df 2; 57 at 5% significance level was 3,17. Fhit <Ftab means that there is no interaction between the model of learning and motivation on mathematics achievement.

Abstract

The aims of this research are to improve student’s motivation and their achievement in learning Mathematics at Mathematics lesson students class VIIA SMP Negeri 3 Temanggung year 2012/2013. The action hypothesis of this research is the open-ended approach in studying Mathematics can improve the learning motivation and student’s achievements in learning Mathematics for students class VIIA SMP Negeri 4 Temanggung year 2012/2103 .The research belongs to class action research that happened by collaborating with Mathematic teachers. The subjects of this research are the students of VIIA SMP N 3 Temanggung that consist of 32 students. The data collecting technique of this research are by using observation sheets, questionnaires sheets and test. The data analysis technique for the observation sheet and the questionnaires sheet is by counting every indicator. Then for the students achievement is counted by counting the average score of the test. The finding of this research shows that after the open-ended approach used in teaching Mathematics, the student’s learning motivation and their achievement in learning Mathematics are improved. Those are seen from the progress of the percentage result of the average on the observation of student’s motivation in every cycle, that is pre cycle on 73, 13% and improve on the cycle 2 on 80, 38%, besides that, the result of the questionnaires sheet also been supported by the result of student’s learning motivation questionnaires which are improve for each cycle, that are pre cycle on 71,00% then improve again to 81,00% and improve again on the cycle 2 to 88,97%. Besides that, the average of the students achievements on Mathematics study are improve from the first competence 70,23 become 80,17 on the cycle 1 and for the cycle 2 become 86,45. Remembering the open-ended approach can improve the learning motivation and can improve the student’s achievement on Mathematics, the researcher hopes schools can use and implement the approach as the learning model
