Abstract

This study aims to determine the use of project-based Moodle science learning integration on the city noise theme. The type of research used is descriptive qualitative. The research was conducted in three junior high schools in the city of Semarang in the even semester of the 2020-2021 academic year. Based on the results of the study, teachers in each school responded positively to the use of Moodle science learning integration with the theme of city noise because the content in it was following the needs of teachers in science learning. In the first and second project assignments, there were only 10 students each who submitted their assignments. Based on the results of the study, it can be concluded that the use of project-based Moodle science learning integration on the theme of city noise is following the needs of science learning in schools, but has not been able to increase student activity optimally in the science learning process. Constraints found in the use of project-based integration of moodle science learning on the theme of city noise online are limited infrastructure, internet quota, learning time, low student interest and motivation, and lack of parental supervision in the implementation process

Abstract

This study aims to develop ISLE-based STEM learning media and utilize standing wave resonance tube teaching aids to study the phenomenon of stationary (standing) waves. The method used is research and development (R&D) with the ADDIE development model (Analysis, Design, Develop, Implement, and Evaluate). The results obtained from this study are learning media in the form of Practical Teaching Aids (APP), wave simulation programs and student worksheets for traveling wave and stationary wave experiments. The two learning media have gone through the validation process of material experts and media experts and have been declared suitable for use/implementation by students. The developed APP makes it easy for students to visualize stationary waves in a tube. Student worksheets which is prepared using the ISLE-based STEM model approach, is used as a guide in achieving learning objectives by building students' thinking concepts about stationary wave material through resonance tube experiments. The use of APP provides a visualization display of experimental results so that it helps students understand the concept behind physics processes that are invisible like standing waves

Abstract

This study aimed to identify the honesty level of students in online exams assisted by supervisory robots on the autoproctor application as an effort to improve the quality of online learning. The sample of this study were 34 students majoring in Physics Education FKIP USK who were selected randomly. Data were collected from test results using a google form embedded the autoproctor to detect student honesty during online exams and student response results from an honesty questionnaire based on four indicators developed by Ashton, M. C, et.al namely: sincerity, fairness, greed avoidance, and modesty. The data were analyzed using quantitative descriptive analysis. This study shows the honesty level of students recorded by the application is medium level and is supported by the results of honesty questionnaire responses. The response results show the level of honesty is in the very high to the medium range, while the test results using the autoproctor are in the very high to the very low range. There were some students who detected high honesty levels based on the results of the questionnaire responses but were detected very low on the autoproctor application. In applications, it was found evidence of fraud by students but they were not true after further observation, so it was necessary to inform the rules that must be obeyed using this application before the test. The findings of this study could be the basis for sustainable professional development using the autoproctor application in detecting student honesty in online exams
