The background of this research is the lack of competence of physics teachers in using physics KIT. This research was conducted with the hope that there will be an increase in the competence of senior high school physics teachers in West Pasaman in using the physics KIT. This research was conducted with a quasi-experimental design and one group pretest-posttest. This study has a population of all physics teachers who join physics teachers group in West Pasaman Regency. The sample was taken by using simple random sampling technique, selecting 22 teachers as representatives of the physics teachers group in West Pasaman Regency. The results showed an increase in teachers' competence in using the physics KIT after mentoring the use of the physics KIT. The increase in teacher competence can be described through the value of again, the N-gain value obtained is 0.33 (moderate). This means that the teacher's competence in using the physics KIT can increase after mentoring the use of the physics KIT.

This study was designed to examine the possible constraints that can affect high school students’ mathematics performance in five selected high schools in Awi-zone and west Gojam. Observations and reports from examining bodies revealed that a high percentage of secondary school students continue to perform poorly in mathematics examinations. From a total of nine high schools, five were selected using simple random sampling technique. The respective sections were selected using purposive sampling techniques. Four sections were selected from each school. Then, two hundred samples of students were employed using comprehensive sampling technique. To obtain data, questionnaire, classroom observation, and semi-structured interviews were used. Fifty students from each school were selected using simple random sampling technique for the questionnaire. Similarly, three teachers from each of the sample school were selected using simple random sampling technique for the questionnaire, classroom observation and interview. The quantitative data were analyzed using one sample t- test whereas the qualitative one was analyzed using descriptive interpretations. The findings showed that students have laid claim on the problem of scoring passing mark as a result of poor mathematics performance. In addition, the result indicates that teachers possess the theories and their application of indirect instruction, organizing mathematics lessons, classroom management using assessment techniques. The findings also implied that there are opportunities to improve students’ performance in mathematics in the high schools to the expected level. Furthermore, the findings showed that paraphrasing math word problems improves performance of some students. In relation to the findings of the study, recommendations are forwarded.

Communication technology developing rapidly in this globalization era makes a lot of people use gadget as one of any media for communicate and entertaiment. Not only adult but teenager in school age. That increasing use of gadget for parent and teenager cause a new phenomena in family called alone together. This reasearch aim to give a description about the effect of alone together phenomenon on family interaction. This reasearch was conducted in 209 Junior High School, East Jakarta. This data reasearch processed by using simple random sampling technique and this reasearch use survey methode. Total samples 185 active students in 209 Junior High School, East Jakarta. This whole reasearch data are using SPSS 2.2 and Microsoft Excel. The prerequisite test in this study use kolmogorov smirnov for normality test and the result shows that data are not normally distribute. So the reasearch use non parametric calculation. Result of correlation coefficient test are obtained >  that is equal to -0,353 > 0,138. Result of t-test with significancy level 0,05 obtained >  that equal to -5,688 > 1,97 the result explain that there are a negative and significant correlation between alone together and family interaction. Alone together give 15% effective contribute to family interaction and the other 85% determine by other factors. Abstrak Teknologi komunikasi yang berkembang dengan cepat di era globalisasi membuat banyak masyarakat menggunakan gadget sebagai salah satu media atau sarana berkomunikasi dan mencari hiburan. Tidak hanya orang dewasa melainkan remaja dalam usia sekolah. Meningkatnya penggunaan gadget yang berlebih pada orang tua dan remaja tersebut menimbulkan suatu fenomena baru di dalam keluarga, yang disebut dengan alone together.
