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. Keywords: Direct Instruction Model.

Abstract

This research aim to to increase activity and result of learning student by exploiting multimedia in course of learning to teach in SMA Country 1 Great River. Peculiarly this research aim to 1) Analyzing how far Acquirement learn the student in intellectual efficiency domain at trig items after taught with the exploiting multimedia 2) Mendeskripsikan Respon student of at trig items after taught with the exploiting multimedia 3) Mendeskripsikan of Pattern aktifitas learn the student of at trig items after taught with the exploiting multimedia.Hereinafter pursuant to research result indicate that the exploiting multimedia in course of mathematics study of at trig items can improve the activity and result of learning student. With the active student percentage 51,51 %, complete percentage result of learning 78,78% and percentage of is make-up of motivation and also enthusiasm learn the student 96,9 % by respon is positive pertained by a goodness. recommend from this research 1) Pursuant to research finding that exploiting multimedia in study of mathematics of trig items very effective, is therefore suggested for all education ladder exploit the multimedia in course of learning to teach 2) If we like to create the atmosphere learn more voluptuous exploit the lah multimedia in course of learning to teach 3) Expected to school head to can to equip, providing facility of related to study media of so that can be used at process learn to teach at school. Key words: Multimedia, trigonometri, activity learn the student, respon of student and achievement learn student.

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

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.

Abstract

The aim of this research is to find out the improvement of students learning output use cooperative learning teaching type think pair share (TPS). The form of research is the classroom action research consisting of two cycles with the steps of planning, action, observation and reflection. The subject of this research is students grade 8 of SMPN 1 Kalis. Quantitative data is taken from the pretest and postest, then is defined the average scores.  The result of this research shows that there is an improvement of average of learning output is 33,75 in the first cycles and then the second cycles is 41,25. The increase of completion of the learning output is the first cycles is 90,63 %, while the second is 93,75 %. The observation result of the learning prosess showed that the students learning activities improved and it affected the students learning output. The learning process use cooperative learning model with think pair share type is expected to be used by physics teachers to teach. Keys word: Learning output students, Cooperative type Think-Pair-Share (TPS), Pressure.
