JUNIOR HIGH SCHOOL STUDENTS' PERCEPTIONS OF PROBLEM BASED LEARNING MODEL IN SCIENCE LEARNING

Febby Febriani — 2024-11-11

Problem Based Learning (PBL) is a learning approach that is often used in education in recent years. The purpose of this article is to find out how junior high school students perceive PBL model in science class and the benefits of PBL model in science learning. To find data related to junior high school students' perceptions of problem-based learning models in science classes, the researcher conducted a systematic review of several relevant sources with a period from 2014 to 2023, following the principles of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Based on the research results, it is known that the problem solving ability of students who learn using the PBL model is better than students who learn with conventional models. The results of this study prove PBL as an effective learning method for science compared to conventional teaching methods. PBL method is perceived to improve students' knowledge and communication skills. Based on several research results that have been conducted, it can be concluded that the PBL model has a positive impact on learning.

Elmesa Putri — 2024-11-11

This study aims to determine the effect of R2L model on scienctific literacy competence of students on the classification of Living Things learning material. The type of this research is a quasi experiment with nonequivalent control group design. This research was conducted in the 7^th grade of SMPN 7 Payakumbuh, West Sumatra. The sampling was taken by purposive sampling technique to get 32 students of class VII.I as experimental group and 23 students of class VII.II as control group. The instrument used is a test of science literacy questions as many as 16 questions with 3 forms of questions. The results showed that the use of the R2L model increase the science literacy competence of students. The important syntax in supporting the improvement of students' scientific literacy competence is at the detailed reading and note-making stages. This stage allows students to read the reading text attentively and find important words in the text.

Kuntum Khaira Ummah — 2024-11-11

This study aims to determine the effect of using Motion Graphic Video-based science learning media as a supporting tool for science learning in junior high schools in Indonesia. This study uses the Systematic Literature Review method through analysis of the findings on 31 scientific articles found. The search for scientific articles is carried out through the google shcolar database with a publication range of 2010 to 2021. The technique of presenting research data is presented in the form of graphs and tables. The results showed that there was an effect of using motion graphic video media on the results and learning processes of students in the science class. The effect of using motion graphic video on the learning process can be seen in the indicators of learning interest, responsiveness, creativity, student enthusiasm, student activity, visual activity, speaking activity, listening activity, mental activity and emotional activity of students. In addition, it was found that there was an increase in student learning outcomes on indicators of cognitive abilities in the form of high-level thinking skills, scientific, critical and creative thinking, an increase in affective abilities in the form of collaborative abilities through the application of motion graphic video media. Motion graphic video media is effectively used as a tool to support science learning in junior high schools in Indonesia.

Fathia Zahra — 2024-11-11

This research is based on the preliminary study conducted at SMPN 16 Padang which found that students' learning outcomes in science teaching are still considered suboptimal. This is indicated by several students' scores that have not yet met the Learning Outcome Completion Criteria of 80. This research aims to determine the effect of Problem-Based Learning (PBL) model assisted by PhET simulations on the learning outcomes of eighth-grade students at SMPN 16 Padang. The type of research is a quasi-experiment with a non-equivalent control group design. The population in this study is all the eighth-grade students of SMPN 16 Padang. Sample collection was conducted using purposive sampling techniques. Thus, the research samples were obtained from students in class VIII 2 and VIII 4. The research samples consisted of experimental class applying the Problem-Based Learning model assisted by PhET simulations and control class using the conventional learning model. Data collection was conducted through tests administered before (pretest) and after the treatment (posttest) on the experimental and control classes in the form of multiple-choice questions. The obtained data were analyzed using inferential statistical analysis, and the results of the two-sample t-test for the pre-test and N-gain were 0.002 for the pre-test significance and 0.000 for the N-Gain significance, which means was rejected or there was a significant difference between the two groups because the significance value (p) was less than 0.05. Thus, it can be concluded that there is a significant influence of the application of the PBL learning model assisted by PhET simulations on the learning outcomes of eighth-grade students in the subject of light and optical instruments.

LITERATURE STUDY: STUDENTS' CURIOSITY ABOUT STEM-PBL MODEL IN SCIENCE CLASSROOM

Dara Adinda Putri — 2024-11-11

Problem Based Learning (PBL) is a form of problem-based learning that is given to students to apply knowledge to issues or problems as a form of problem solving. Its integration with the STEM (Science, Technology, Engineering, and Mathematics) approach can train students to apply their knowledge in making designs as a form of problem solving related to the environment using technology. The purpose of writing this article is to find out the improvement, response and impact of students' curiosity by using the STEM-PBL learning model in science class. The method used is content analysis, with the principles of Preferred Reporting Items For Systematic Reviews and Meta Analysis (PRISMA). Based on the results of this study, it shows that students' curiosity towards STEM PBL in science classes shows significant results overall because the application of hands-on activities as a learning strategy is able to form various skills and provide positive results and even increase.
