ABSTRACT
Science education is a very important science to learn and discuss because it is tightly related to everyday life. The phenomena that exist in the environment are related to science, so science education is important to learn. In addition, research on science education is important. This research aimed at the analysis of bibliometric data in the field of science education by using the mapping analysis software VOSviewer. Research data is also obtained through the reference manager application. The search results from the keyword "Science education" are used as data in this research. From the search results in the 2017-2021 range, we obtained data from as many as 991 relevant published articles. The results showed that from 2017 to 2021 the number of research on science education continued to decline. A significant decrease occurred in 2019. Until now, the exact causative factor has not been found, but one of the suspected factors is the result of the deployment of Covid-19. The conditions and situations of the pandemic have resulted in researchers experiencing a decrease in the productivity of their research activities. The results of this study show how important it is to use bibliometric analysis data. This research demonstrates the score of the analysis bibliometric about providing information on how the phenomena occur. This research was meant the assist and serve as to reference for researchers undertaking as well as deciding on research topics, especially about science education. © School of Engineering, Taylor's University.
ABSTRACT
The purpose of this study was to demonstrate distance learning innovation in teaching chemistry in vocational school using the concept of isotherm adsorption of carbon microparticles. The subjects were 60 vocational school students in Bandung, Indonesia, who took a 15-question pre-test and post-test with a learning video for supporting distance learning process. The subjects were focused to understand the successful teaching process, which were divided into the control class and the experimental class. The control class was done by giving a video containing conventional teaching process (without experimental demonstration), while the experimental class was done by giving a video containing experimental demonstration. To support the teaching process. the experimental video was chosen as the suitable teaching medium, including the production of carbon microparticles, adsorption measurement, data analysis, and an explanation of the adsorption mechanism. The results showed increases in the post-test scores compared to the pre-test. The t critical two-tailed value was 2.04, which was higher than the t statistic value (-2.52), ensuring the successful teaching for improving the students' understanding on carbon adsorption phenomena. The learning video was provided visual and audio experiences. Video learning media gave positive impacts to students' understanding, which was prospective for distance learning process. However, additional experimental demonstration inside the video learning media enhanced student's interest in particular subjects and motivated them to learn more about the teaching subject, in which this become new innovation in the distance learning process. This study demonstrated the importance of combination between experimental demonstration and video as a teaching media for improving students' comprehension. which can be implemented during special condition, for example COVID-19 pandemic.
