Abstract

Conceptual understanding involves students' abilities in the aspects of translation, interpretation, and extrapolation. A way to increase conceptual understanding is to use excel-based modeling (EBM). However, the use of excel-based modeling (EBM) has not been applied in physics learning at the junior high school level. This study aims to test the effectiveness of project-based learning assisted by excel-based modeling to increase students' conceptual understanding of wave material. The sample of this study were students of class VIII-1 junior high school who were selected using the purposive sampling technique. This study used a one-group pretest-posttest design. Research data determine the effectiveness of using excel-based modeling using a pretest and posttest in the form of 7 identical essay questions. The data obtained were analyzed using a paired-sample T-test. After the treatment, data on the increase in the value of each indicator of concept understanding were obtained, namely 91.18 (translation), 86.65 (interpretation), and 83.09 (extrapolation). In the end, excel-based modeling is quite effective in improving students' understanding of concepts.Keywords: Conceptual Understanding, Excel-based Modelling, Project-based Learning DOI: http://dx.doi.org/10.23960/jpf.v9.n1.202105

Abstract

This study aims to obtain an instrument of teacher beliefs about learning and teaching in hybrid learning in the post-COVID-19 (New Normal) era. In addition to producing a questionnaire instrument, this study looks for the relationship of belief to learning and learning with Confirmatory Factor Analysis (CFA). The research subjects were selected through a random sampling technique (through a lottery) by several teachers/prospective teachers of physics education at schools and in higher education institutions. Structural equation modeling (SEM) analysis was performed using AMOSS v26 using a strong categorical data estimator. The SEM results show the teaching and learning conceptions questionnaire in the marginal fit category (RMSEA) poor fit (NFI, RFI, IFI, TLI, and CGI), in addition, it is shown that the indicators have good internal consistency but lack formation in the latent variance variable. Meanwhile, the results of the SEM Epistemological Beliefs Questionnaire are in the poor fit category, both seen from the RMSEA and NFI, RFI, IFI, TLI, and CGI. Indicators of Fixed ability, learning effort, Authority, and Certainty Knowledge have good internal consistency, while Authority internal consistency is not good. The variance on the Epistemological belief questionnaire extracted from the indicators is greater for the formation of latent variables.Keywords: Adaption, Epistemological belief about teaching-learning questionnaire, Preservice physics teacherDOI: http://dx.doi.org/10.23960/jpf.v10.n1.202213

Abstract

Schools must have the 4C abilities, notably creative thinking, to keep up with the advancement of science and technology in the 21st century's educational institutions. The ability to think creatively strives to involve activities, analyze, synthesize, generate conjectures, create something new, and utilize the knowledge acquired in practical ways. Some studies show that students' creative thinking skills in momentum and impulse materials are not optimal. One of the factors that cause students' low creative thinking skills is the learning process. This study aims to provide an overview of students' creative aptitudes on momentum and impulse topics. This study used a mixed method with an embedded experimental design. At SMA 1 Menggala in Lampung, this study was carried out. 28 students of class X MIPA 2 involved in the study were taken as samples with a saturated sampling technique. For this study, the students participated in tests and interviews. Of the four essay questions on momentum and impulse that made up the creative thinking ability exam each validity value (0.686) and reliability (0.610) had a high category. A creative mind is characterized by fluency, flexibility, originality, and elaboration. Problem-based learning models can help students' creative thinking skills, according to the findings of research on the subject. According to the results of the investigation, most students have a high level of creativity on the indicator of fluency. The problem-based learning model is successful in enhancing the ability to think creatively and is expected to be applied in further research on different topics.Keywords: Creative Thinking Ability, Problem-Based Learning, Impulse and MomentumDOI: http://dx.doi.org/10.23960/jpf.v11.n1.202304
