Pada konteks penilaian berskala internasional seperti PISA, kompetensi pemecahan masalah dalam bidang matematika dan sains terkait permasalahan nyata merupakan fokus pengembangan kompetensi representasi dan literasi matematis siswa. Mengingat pentingnya pemecahan masalah, kemampuan representasi dan literasi matematis, maka penelitian ini bertujuan untuk mengetahui pengaruh pendekatan problem solving terhadap kemampuan representasi dan literasi matematis siswa SMP. Metode yang digunakan pada penelitian ini adalah metode eksperimen kuasi (quasi experimental), dengan desain penelitian yang digunakan adalah Randomized Posttest-Only Control Group Design, yakni dua kelas yang telah dipilih secara acak, selanjutnya diberikan perlakukan yang diakhiri dengan tes kemampuan representasi dan literasi matematis pada kedua kelas tersebut. Berdasarkan hasil kajian dan analisis data dengan bantuan SPSS 24, maka dapat disimpulkan bahwa pembelajaran matematika dengan pendekatan problem solving berpengaruh terhadap kemampuan representasi dan literasi matematis siswa SMP, khususnya di kelas VIII SMP Negeri Banjarmasin. Terlihat jelas perbedaan cara menyelesaikan masalah yang diujikan kepada siswa kelas eksperimen dan kelas kontrol. Melalui pendekatan problem solving, terbukti dapat menjadikan siswa terbiasa ketika menjumpai soal-soal pemecahan masalah selevel PISA atau TIMSS.The effect of problem solving approach to the ability mathematic representation and literature students AbstractIn the context of international scale assessment such as PISA, problem-solving competence in the field of mathematics and science related to real problems is the focus of developing students' mathematical representation competence and literacy. Given the importance of problem solving, the ability of representation and mathematical literacy, this study aims to determine the effect of problem solving approach on the ability of representation and mathematical literacy of junior high school students. The method used in this research is quasi experimental method, with the research design used is Randomized Posttest-Only Control Group Design, ie two classes that have been chosen randomly, then given treatment which ends with the test of representation ability and mathematical literacy in both classes. Based on the results of study and data analysis with the help of SPSS 24, it can be concluded that mathematics learning with problem solving approach affects the ability of representation and mathematical literacy of junior high school students, especially in class VIII SMP Negeri Banjarmasin. There is a clear difference in how to solve the problems tested to the experiment class and control class students. Through the problem solving approach, it is proven to make the students accustomed when encountering problem solving problems at PISA or TIMSS level.

The aim of this research was to investigate the effect of problem-based learning on students’ beliefs about physics and learning physics. The research design is quasi-experimental, non-equivalent control group design with samples were senior high school students grade XI at SMAN 1 Jambi City. The research used the Colorado Learning Atttudes About Science Survey (CLASS). Through data analysis using ANCOVA Test can be seen that there was no significant result effect of problem-based learning on students’ beliefs about physics and learning physics. The study’s finding indicates that students’ beliefs about characteristic and obtaining knowledge are difficult to change. Nonetheless, the use of various learning models that focus on the formation of the model building on the physics world through problem solving that are contextual and real, as well as providing opportunities for students to actively engage in problem solving can help students develop the belief that they have about the physics from novice-like belief into expert-like belief.Penelitian ini bertujuan menginvestigasi pengaruh penggunaan model pembelajaran berbasis masalah terhadap belief siswa tentang fisika dan pembelajaran fisika. Desain penelitian kuasi eksperimen non-equivalent control group design dengan sampel siswa kelas XI Sekolah Menengah Atas Negeri (SMAN) 1 Kota Jambi. Instrumen penelitian yang digunakan adalah kuesioner the Colorado Learning Attitudes About Science Survey (CLASS). Hasil uji Ancova terlihat bahwa tidak ada pengaruh signifikan penggunaan model pembelajaran berbasis masalah terhadap belief siswa tentang fisika dan pembelajaran fisika. Temuan penelitian mengindikasikan bahwa belief siswa tentang karakteristik dan cara memperoleh suatu pengetahuan sulit untuk diubah. Meskipun demikian, penggunaan berbagai model pembelajaran yang berfokus pada pada pembentukan model (model-building) dari dunia fisika melalui pemecahan masalah-masalah yang bersifat kontekstual dan nyata, serta memberikan kesempatan siswa untuk aktif terlibat dalam pemecahan masalah dapat membantu siswa mengembangkan belief yang mereka miliki tentang fisika dari belief sebagai seorang pemula (novice-like belief) menjadi belief sebagai seorang ahli (expert-like belief).

The Difference

The misconception of the Solar System topic is still found in students so that it becomes one of the obstacles in the learning process. The purpose of this study is to analyze the effectiveness of the implementation of Predict-Observe-Explain-Apply (POEA) learning to change the junior high school students' conception in the Solar System topic. Quasi-experimental research with the non-equivalent control group design was conducted in one of the private junior high schools in Bandung city. Samples were selected based on the test of the average significance of the pretest score of the population. Furthermore, 30 students of the experimental class and 32 students of control class were selected. The research instrument, which consisted of 15 four-tier diagnostic test questions about Solar System were used to collect data before and after treatment. The tests were analyzed quantitatively by using the Mann-Whitney statistical test to determine the significance of the difference in the acceptable conception changes (Acceptable Change) of students in the experimental class with changes in the conception of students in the control class. The results of the research show that the implementation of POEA learning is significantly more effective than POE learning in changing the conception of Solar System topic. The findings of this study can be an alternative for junior high school teachers in planning learning about the Solar System, especially in an effort to change students' misconception about the Solar System.

Inquiry-based science issues approach facilitates the development of scientific skills through research activities on surrounding science issues. The purpose of this research was to understand the influence of Inquiry-based science issues on practical skills of Junior High School students. This research employed quasi-experimental research method, equipped with pre-test, post-test non-equivalent control group design. The sample of sixty junior high school students in Yogyakarta was picked for this study.  The instruments used were observation sheets on practical skills, practical skills test, and instructional learning sheets. The data collected were analyzed using N-Gain, percentage, and Analysis of Covariate (ANCOVA) at 0.05 significance level. The result revealed that Inquiry Science Issues was more effective in fostering students’ practical skills than the scientific approach. There was a significant effect of treatment on students’ practical skills while no interaction between approach and prior knowledge of students. Moreover, the data of practical skills through the observation sheets in the experimental class had higher percentage compared to the control class, 80.36%, and 70.61% respectively.

Two Phases

This study aimed to increase the understanding of sexuality at the age of puberty through "Remaja MUDA" psychoeducation to increase anti-premarital assertiveness. The module validation was conducted in two phases. First, the content validity was conducted through judgement from ten raters. The results of Aiken’s V analysis showed score sbetween 0,8-0,975 which means that the module has good content validity. Second, the empirical tests to determine the effect of modules on anti-premarital sex assertiveness. This research was quasi-experimental research using an untreated control group design with pretest and posttest. The participants were 30 junior high school students (aged 13 to 14) in Yogyakarta. The results of independent samples t-test showed that anti-premarital sex assertiveness in the experimental group had a significant difference compared to control group (t = -10.063; p < 0.05). The results of the study indicated that the "Remaja MUDA" module can be used to increase anti-premarital sex assertiveness.
