This research aims to discover the effect of scaffolding causalitic thinking approach with preliminary task toward impulse and momentum student’s problem solving ability (PSA) at X grade. The type of this study is quasi experimental research with post-test only control group design. The research population is all student’s of X MIA SMAN 8 Mataram with 33 chosen students from X MIA 1 as experimental class and 32 chosen students from X MIA 3 as control class as the sample by using cluster random sampling. Based on the research finding, it is found that the average score of problem solving ability in experimental class is 65, while the average score of PSA in control class is 53. The PSA data of two classes were normal distributed. According to the result of homogeneity test, it was obtained that both are homogen. The PSA data were analyzed with t-test polled varians. The data analysis showed that tcount was 3,3690 and ttable with significant rate (5%) was 1,9987 which means tcount >ttable.Based on that fact, it can be concluded that there is an effect of scaffolding causalitic-thinking approach with preliminary tasks toward PSA impulse and momentum students at X grade.

This research was aimed to find out or not Commentary Strategy has significant effect in teaching speaking, and has correlation students self-confidence and their speaking ability. The research was quasi- experimental method and design was non equivalent control group design. The population of this research was the whole students of second grade students of MA NW AIKMEL, the total population is 43 students that consisted of two class. The sample was taken from of the second grade  students which  consisted of 43 students. The data were gained from pre-test and post-test of oral  and questionnaire. The instrument was in form of test and questionnaire. In analyzing the data, t-test formula was used. The finding showed that the mean score of post-test for experimental is ( 60,70 ) higher than control ( 49,61 ). Further, the result of t-test showed  ( 1,76 ) is higher than t-table ( 1.684 ) with the degree of freedom (df) = 95 at the significant level  = 0. 05. It mean that the alternative Hypothesis  ( Ha) was accepted and Null Hypothesis  was rejected . and  then there is correlation between students self-confidence and their speaking ability, it was found in experimental group r-test showed r is higher than the r table (r= 0,791 ≥ rt = 0, 444) and  for control group r-test showed r is higher than the r table ( r =  0, 482 ≥ rt = 0, 0,444). So it can be concluded that commentary strategy has significant effect towards students self-confidence in speaking ability and there is correlation between students self-confidence and their speaking ability at the second grade students of MA NW AIKMEL in academic year 2016/2017.

Problem solving is a process that has been implemented in order to obtain a solution to a problem that is carried out in stages. Teamwork is the ability of individuals to work together with others and aims for members to be able to participate in the team and understand their duties. This study aims to determine the ability to solve problems and teamwork (teamwork) in children aged 10 years using puzzles. This research is an experimental study with a quasi-experimental design: non-equivalent control group design. The participants in this study were 8 children aged 10 years consisting of 5 boys and 3 girls. The data collection in this study was the acquisition of time in the preparation of puzzles. The data that has been obtained is then analyzed using the t-test (t-test). The results of this study indicate that the experimental group has faster problem solving than the control group because of the learning outcomes of teamwork.

SMA 5 and SMA 21 are the leading schools in Makassar City which have a Youth Counseling Information Center. Previous research looked at the influence of game simulation and brainstorming on the knowledge and attitudes of stundent about reproductive health for high school adolescents in Makassar City, including SMA 5 and SMA 21, but the results did not have effect on students' knowledge and attitudes. Therefore, the researcher took the initiative to provide another intervention in the form of counseling. This study aims to determine the effect of counseling on knowledge and attitudes about risky sexual behavior among students in SMA 5 and SMA 21 Makassar City. This study used a quasi-experimental design with a randomized pre test post test control group design. A sample of 76 students of class XI SMA 5 and SMA 21 Makassar City, using simple random sampling technique. Data collection was using a questionnaire. Statistical analysis used paired t-test and independent samples t-test. The results showed that there was an effect of counseling on knowledge (p = 0.002) but there was no effect on attitudes (p = 0.865) in SMA 5 and SMA 21 Makassar City. It is suggested that SMA 5 and SMA 21 Makassar City be active in conducting counseling, especially counseling about attitudes, so that students have positive attitudes about risky sexual behavior.

Penelitian ini bertujuan untuk mengetahui pengaruh pelatihan three corner drill terhadap kelincahan dan power otot tungkai. Jenis penelitian adalah quasi experimental dengan rancangan the non-randomized pretest-posttest control group design. Subjek penelitian yang digunakan siswa putra peserta ektrakurikuler sepak bola SMPN 2 Pekutatan. Data post-test kelincahan dan power otot tungkai pada kelompok perlakuan dan kelompok kontrol dianalisis dengan uji-t independent pada taraf signifikansi (α) 0,05 dengan bantuan program SPSS 16.0. Berdasarkan hasil uji-t independent didapatkan hasil : (1) untuk variabel kelincahan, hasil perbandingan kelompok perlakuan dan kontrol didapatkan nilai thitung = -2,948 , dengan nilai signifikansi 0,009, (2) untuk variabel power, hasil perbandingan kelompok perlakuan dan kontrol didapatkan nilai thitung = 3,176, dengan nilai signifikansi 0,005. Nilai signifikansi hitung lebih kecil dari nilai α (Sig < 0,05), dengan demikian hipotesis penelitian “pelatihan three corner drill berpengaruh terhadap peningkatan kelincahan dan power otot tungkai pada siswa putra peserta ektrakurikuler sepak bola SMPN 2 Pekutatan” diterima. Dari hasil analisis data dan pembahasan disimpulkan bahwa : (1) Pelatihan three corner drill berpengaruh terhadap peningkatan kelincahan pada siswa putra peserta ektrakurikuler sepak bola SMP Negeri 2 Pekutatan (2) Pelatihan three corner drill berpengaruh terhadap peningkatan power otot tungkai pada siswa putra peserta ektrakurikuler sepak bola SMP Negeri 2 Pekutatan. Kata Kunci : kelincahan, daya ledak, three corner drill The purpose of this research was to find out the effect of three corner drill training toward the increased agility and power muscle of legs. The type of research was a quasi-experimental and the design of research was the non-randomized pretest-posttest control group design. The subjects were man’s student football extracurricular participants of SMPN 2 Pekutatan. Agility and muscle power of legs posttest to the treatment group and the control group were analyzed by independent t-test at significance 0,05 with SPSS 16.0. Based on independent t-test results were showed : (1) to the agility variable, the comparison of the treatment and the control group values obtained t = -2,948, with a significance value of 0,009, (2) to muscle power of legs variable, the comparison of the treatment and the control group values obtained t = 3,176, with a significance value of 0,005. Calculated significance value smaller than the value of 0,05 (Sig < 0.05), thus the research hypothesis "three corner drill training affect the increased agility and muscle power of legs in football extracurricular participants of SMPN 2 Pekutatan " was received. From the analyzed and discussion were concluded that : (1) three corner drill training effect the increased agility in football extracurricular participants of SMPN 2 Pekutatan, (2) three corner drill training effect the increased muscle power of legs in football extracurricular participants of SMPN 2 Pekutatan. keyword : Agility, power, three corner drill
