Abstract

This research utilizes a frequency generator application on smartphones with the aim of enhancing students' understanding of the concept of sound resonance in closed organ pipes. The study employs a pretest-posttest design with a control group that was not selected randomly. The method used is non-probabilistic sampling (convenience sampling). The sample used in this study consists of fourth-semester Elementary Teacher Education (PGSD )students who are taking the science learning course. Data collection was conducted using a Concept Understanding Instrument Sheet. The percentage of students' concept understanding above the average increased from 40.1% to 63.4%. This indicates that the concept understanding attained improved after receiving treatment in the form of the frequency generator application. The N-Gain test results yielded an average score of 0.68.

Abstract

Scientific work skills are used to build physics knowledge correctly and logically. which can be developed through practical activities. However, not all schools have adequate practical equipment. Observations show that SMA Islam Diponegoro still does not have a physics laboratory and experimental equipment is still limited in number and type, so practical activities are rarely carried out, which has an impact on students' scientific work skills that have not developed optimally. Therefore, community service activities were carried out in the form of Open Lab, which aims to provide students with experience in conducting practicals through concrete practical media and virtual PhET. Community service activities were carried out in the form of training and mentoring for practicals attended by 20 students. Based on the results of the scientific work ability assessment rubric, it was found that students' abilities were in the good category with an average scientific work ability score of 75.35. Indicators of scientific work ability that developed very well after the practicum were observation, implementation of the practicum, and presentation of results. However, aspects of data analysis and evaluation still need to be improved because the scores were lower than other indicators.

Abstract

The achievement of learning outcomes is not only influenced by models, methods, or learning strategies, but there are several other factors that can affect the achievement of the learning process. The selection of the right model, method, or media will facilitate educators in creating a pleasant learning atmosphere and in achieving learning outcomes. The inquiry laboratory learning model, assisted by Phyphox-Excel, can help students understand physics concepts, both during the learning process (performance) and at the end of learning (cognitive aspect). The purpose of this research is to determine the extent of the influence of the inquiry laboratory model assisted by Phyphox-Excel on students' understanding of physics concepts, as reflected in their Self-Regulated Learning (SRL). Data on students' understanding of concepts were collected through performance assessments and cognitive tests administered at the end of the learning. The results obtained from this research are: (1) the performance assessment of students learning with inquiry laboratory and Phyphox-Excel application is higher than those learning with inquiry laboratory without Phyphox-Excel, (2) the performance assessment of students with high SRL is higher than that of students with low SRL, (3) there is no interaction between the inquiry laboratory Model and SRL on student performance outcomes, (4) there are differences between inquiry laboratory with Phyphox-Excel application and inquiry laboratory without Phyphox-Excel on students' cognitive abilities, (5) there are differences in cognitive abilities between students with high SRL and students with low SRL, (6) there is an interaction between inquiry laboratory and SRL on students' cognitive abilities.
