 The purpose of this research was to determine the effect of problem based learning on the understanding of high school students' concepts. The meta-analysis, which was conducted by summarizing several research articles on the effect of problem based learning on physics learning, was also carried out on students' understanding of concepts in physics learning obtained from articles published between 2015 and 2020. In particular, this research obtained an effect size (ES) =1.005 (high category). The research was conducted by grouping 20 articles into two categories, namely based on the material unit, and based on the approach used. Based on the material unit, there are 15 articles that were analyzed by effect size (ES) and obtained an effect of 0.82 with a high category with a percentage of 54.5%. The material with the greatest influence is temperature and heat with ES = 1.78, while the grouping based on the approach used there are 5 articles that were analyzed with the results of the effect size (ES) analysis of 1.19 with a high category with a percentage of 60%. The approach that has the most influence on PBL is HOTS with ES= 3.02. From the results of this study, it can be seen that the PBL model has a significant effect on physics learning. The hope of this research is that it can be a reference in reviewing the application of PBL in learning in Indonesia.

Peer assessment training has appeared as potential new tools for enhancing Arab English as foreign language (EFL) high school students on writing performance. The purpose of this research was to investigate the effect of using peer assessment training on writing performance among Arab EFL high school students. One hundred and twenty students aged fifteen and sixteen years old participated in this study with an equal number of male and female students. The students were from two Arab high schools in Malaysia. This study employed a quasi-experimental research design. Data was collected using Analytical Marking Scale (Alderson, et al., 1995) to assess student’s writing performance in the pretest and posttest. The result of this study shows that there is a significant difference in the writing performances between the experimental and control groups at P < 0.001. The findings suggests that students who have been exposed to peer assessment training write a better draft compared with those students who were only given conventional training in writing an essay, and without the benefit of peer feedback.

INTRODUCTION: Low levels of hamstring flexibility may trigger certain acute and chronic pathologies and injuries. Poor flexibility is observed among teenagers and several authors have recommended the use of specific programs in this population to improve flexibility levels. The Pilates Method (PM) may be an appropriate intervention to achieve this purpose and has rarely been used with this population. Objective: Study was to assess changes in the flexibility of hamstrings after running a didactic PM unit for high-school students.METHODS: This research was developed through a quasi-experimental design. The sample consisted of 66 high-school students divided into experimental group (EG=39) and control group (CG=27). The intervention was carried out 2 times a week for six weeks. Each session lasted 55 minutes divided into three parts: warm-up, main part and cool down. Hamstring flexibility was assessed using the toe-touch test. Paired Student t-test and t-test for independent samples were applied. The size of the effect (d) was determined.RESULTS: The EG showed significant provident in hamstring flexibility (+3.54±3.9cm). The effect size was low (d>d>0,2<0,53), which means that a small proportion of participants improved their results. The control group did not have significant changes after the intervention. In the experimental group, both boys (+3.38± 3.7cm) and girls (+3.85 ± 4.2cm) showed significant improvements. The effect size was low for boys (d>d>0.2<0.53), which means that a small proportion of participants improved their results, and high for girls (d>1.15) which means that a large proportion of participants improved their results.CONCLUSION: This study showed that six-weeks of Pilates training in Physical Education classes has significantly improved the hamstrings flexibility among adolescents.

AbstractThis study focuses on e orts to solve the problems of the low abil- ity students in solving di culties in learning Indonesian language as a subject ma er. The objective of this research is directed at ef- forts of explaining the in uence of Case-based Reasoning (CBR) in the learning towards the students’ problem-solving abilities. The method is a quasi-experimental research focusing on students of MA (Madrasah Aliyah or Islamic Senior High School) in one of the districts in West Java, where the learning in the control class using the Problem Based Learning (PBL). The research showed that the students’ problem-solving abilities by using CBR model is 44% in the high interpretation and by 56% in the moderate interpretation. Whereas the learning using the PBL model is 28% in the high inter- pretation, 56% in the medium interpretation, and 16% in the low interpretation. The value obtained through testing the hypothesis is z-score = -3089 smaller than z-table = -1.64. It means that Ho is refused and Ha is accepted. It further means that there is a sig- ni cant di erence between the problem-solving ability of students of using CBR model in learning and the students using PBL model in learning. The conclusion of this study indicates that the use of CBR model (designed for the study) has proved to give an e ect to the problem-solving skills of students learning Indonesian subject. AbstrakPenelitian ini memfokuskan pada upaya pemecahan per- masalahan mengenai rendahnya kemampuan siswa dalam memecahkan kesulitan-kesulitan ketika mempelajari materi pelajaran Bahasa Indonesia. Tujuan penelitian ini diarah- kan pada upaya menjelaskan pengaruh Case-Based Reasoning (CBR) dalam pembelajaran terhadap kemampuan pemeca- han masalah siswa. Metode penelitian adalah kuasi eksperi- men dengan objek penelitian adalah siswa MA di salah satu kabupaten di Jawa Barat, di mana pembelajaran yang diguna- kan oleh kelas kontrol adalah Pembelajaran Berbasis Masalah (PBL). Hasil penelitian menunjukkan bahwa kemampuan pe- mecahan masalah siswa dengan menggunakan model pembe- lajaran CBR sebesar 44% dalam interpretasi tinggi dan sebe- sar 56% dalam interpretasi sedang. Sedangkan pembelajaran menggunakan model pembelajaran PBL sebesar 28% dalam interpretasi tinggi, sebesar 56% dalam interpretasi sedang dan 16% dalam interpretasi rendah. Sementara berdasarkan hasil uji hipotesis diperoleh nilai zhitung = -3.089 lebih kecil dari ztabel = -1.64. Hasil pengujian ini menunjukan bahwa Ho ditolak atau Ha diterima, artinya ada perbedaan secara signifikan antara kemampuan pemecahan masalah siswa yang menggunakan model pembelajaran CBR dan siswa yang menggunakan model pembelajaran PBL. Simpulan penelitian ini menunjukkan bahwa penggunaan CBR yang dirancang selama penelitian ternyata terbukti memberikan pengaruh terhadap kemampuan pemecahan masalah oleh siswa
