Abstract

This study aims to examine the effect of the blended learning model assisted by Google Classroom on students’ science learning outcomes. The research employed a quasi-experimental design with a pretest-posttest control group. The sample consisted of 31 students in the experimental class and 30 students in the control class, selected using simple random sampling. Data were collected using a multiple-choice test. The results showed that the average post-test score of the experimental class (86.58) was higher than that of the control class (65.20). Hypothesis testing using an independent t-test indicated that tcount (10.36) > ttable (2.00) at a 5% significance level. These findings indicate that the blended learning model assisted by Google Classroom has a significant effect on students’ science learning outcomes. These findings indicate that the blended learning model assisted by Google Classroom is effective in improving students’ science learning outcomes.

Abstract

: Thin film characteristics are the properties possessed by the thin film, both physical and chemical properties. The characteristics of this thin film are influenced by several factors, namely the material that makes up the thin film, the thin film deposition method, and the conditions of the thin film deposition process. This research aims to identify and analyze research trends in the characteristics of thin films as electronic devices. 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 thin film synthesis that is widely cited. The data analysis method uses bibliometric analysis assisted by VOSviewer software. The results of the analysis show that the trend of research on the characteristics of thin films as electronic devices indexed by Google Scholar from 2015 to 2024 experienced a fluctuating increase, however, in 2023 there was a decline in the trend of research on the characteristics of thin films as electronic devices. There are many documents in the form of articles, proceedings, book chapters, preprints, and edited books that discuss research into the characteristics of thin films as electronic devices. Key words that are often used in research on the characteristics of thin films as electronic devices are thin film coating, heat transfer characteristic, film characteristic, and photovoltaic characteristic.
