Abstract

In the first cycle  implementing cooperative learning TPS the students’ mastery is as high as 18% of 33 students, the second cycle there is an increase to 48.48%. Because they have not reached minimal passing grade, the cycle is continued to the third cycle with the achievement grade  93.93% which is more than expectation. Therefore, the application of cooperative to study aims to improve students mastery of learning outcomes in circular motion. The study was conducted on the class XF MAN 2 in even semester, using cooperative learning methods TPS with the helping of peer tutors. The researching forms an action research with 3 cycles. The results showed that polling method with the help of peer tutors can improve student learning outcomes in the thoroughness of the material optical instruments.Keywords: Cooperative polling, peer tutoring assistance.

Abstract

The aim of this research was to improve students learning activities through realistic mathematical approaches in class IX B Junior High School Negeri 1 Samalantan in academic year of  2014/2015. The form of this research was classroom action research (CAR). The subjects in this study were the students of class IX B consisting of 34 students. The instrument of this research used  the observation sheet and field notes. The results showed that an increase in the activity after the students were given a realistic mathematical approach on the material similarity. Based on the analysis of the data obtained the increased activity of the students at 11.776% after implementation realistic mathematics approach in two cycles of the action. Students’ activities in asking questions increased by 13.7%. Students’ activities in answering questions increased from 75.49% to 79.4%. While the activity of students in a discussion group increased by 9.81%. Key words: Students’ activities, realistic mathematics approach, similarity.

Abstract

This study was motivated by the study of matter form roots and rank Numbers are still low.Therefore, the teacher will use the Direct Instruction model of which aim to improve student learning outcomes grade IX SMP 23 Pontianak. The subjects were students of grade IX A second semester of 2013/2014. The study lasted for 2 cycles, where in the first cycle showed an average of 71,60 while the learning outcomes in the second cycle, the average results of study show the score 72.14. The mastery learning of students in the first cycle is only 39% of all student in the class, whereas in the second cycle, mastery learning  reaches 57%.Teacher performance assessment by the observer in the first cycle on average 70.95 and the second cycle averaged 72.28. Thus, learning the Direct Instruction model can improve learning outcomes as well as the percentage of mastery learning . Based on the research results, the learning Mathematics Direct Instruction model can be used as an alternative learning strategies that can be implemented in an effort to improve learning outcame.

Abstract

The aim of this research is to characterize impedance, capasitance and relative permitivity of the characteristics of electric thin film ZnS and ZnS:Mn. This research was started from making thin film with different deposition speed and with thermal co-evaporation method in vakum tubes.  The estimation is the characteristics of thin film ZnS impedance and ZnS:Mn was done outside this vacum with various frequency between thousaund to million hertzs, with different deposition speed and the same thickness. Defining impedance of ZnS thin film wich the most optimal frequency would influence capasitance and relative permittivity of the thin film on the characteristics of the electricity. Besides, capasitance and resitance values of ZnS:Mn thin film would change if given different Mn portion on that thin film. From the result of the research, it could be identified as follows. On the area of the thousand to ten thousand Hertz, it was know is that relative permitivity/constante static dielectrics K(0) ZnS:Mn thin film was not the frequency function that it could be regarded as constant like K(o) = 10. The price of capasitance ZnS:Mn was increasing with less Mn amount in that thin film. The price of ZnS:Mn electric resitance is reduced with less Mn amount on  that thin film. Key words: Impedance, thin film ZnS:Mn, co-evaporation.
