Abstract

This study aims to test the effect of problem-based learning model assisted by PhET media on critical thinking skills and physics learning outcomes of high school students. The type of research used is a Quasi experiment twith a pretest posttest control group design. The population in this study were all students of class XI of SMA Negeri 5 Mataram. The research sample used class XI 3 as many as 32 people as the experimental class and class XI 2 as many as 32 people as the control class. The experimental class was given treatment using a problem-based learning model assisted by PhET media and the control class used a conventional model. The test instrument used 5 descriptive questions to measure critical thinking skills and 6 questions to measure students' physics learning outcomes. The hypothesis test used in this study was the manova test. The results of the hypothesis test showed a significance value of 0.007 less than 0.05, so H_0 was rejected and H_a was accepted. Based on these results, it was concluded that there was an effect of the problem-based learning model assisted by PhET media on critical thinking skills and physics learning outcomes of high school students.

Abstract

Research in the field of solar cells continues to increase along with the development of the times and human needs for renewable energy sources. One of the fields of study that is often used as a research topic is the development of Thin Film Solar Cells or known as Thin Film Solar Cells (TFSC). This research aims to identify and analyze research trends of synthesis of Ti02 thin films as solar cell materials. This research method is descriptive and analytical. The data used in this research was obtained from documents indexed by Google Scholar from 2015-2024 using Publish or Perish and Dimension.ai. Research procedures use PRISMA guidelines. The data identified and analyzed are the type of publication, publication source, and the title of research on synthesis of Ti02 thin films as solar cell materials that is widely cited. The data analysis method uses bibliometric analysis assisted by VOS viewer software. The results of the analysis show that research trend on synthesis of TiO2 thin films as solar cell materials indexed by Google Scholar from 2015 to 2024 has experienced increases and decreases. There are many documents in the form of articles, proceedings, chapters, preprints, monograph and edited books that discuss research about synthesis of Ti02 thin films as solar cell materials. Key words that are often used in research about it are dye sensitized cell, electrode, electron, characterization, etc.

Abstract

This study aims to test or examine the effect of the use of virtual laboratories using the Guided Discovery Learning model on students' conceptual understanding abilities in static electricity material. This type of research is a quasi-experimental study with a nonequivalent control group research design. The population in this study were all students of class XII of SMAN 1 Monta. The sampling technique used in this study was purposive sampling with class XII MIPA 2 consisting of 28 students as the experimental class and class XII MIPA 1 consisting of 28 students as the control class. Before and after the treatment, both classes were given a conceptual understanding ability test in the form of essay questions that had previously been tested for their feasibility with validity, reliability, difficulty level of questions, and discriminatory power. The results of the initial test (Pretest) and final test (Posttest) of conceptual understanding ability were analyzed for homogeneity and normality to conduct a hypothesis test. The analysis of the hypothesis test using the t-test obtained a t_count of 3.49 and a t_table of 2.00. Thus, the calculated t_value is greater than the t_table, so H_0 is rejected and H_a is accepted, so it can be concluded that there is an influence of the use of virtual laboratories using the Guided Discovery Learning model on students' conceptual understanding abilities in static electricity material.
