The Impact of Physics Education Technology (PhET) Interactive Simulation-Based Learning on Motivation and Academic Achievement Among Malawian Physics Students

Abstract

The study investigated the impact of PhET simulation-based learning on students’ motivation and academic achievement in learning oscillations and waves among Malawian secondary students. The following research questions guided the study: (i) What were students’ motivation and academic achievement levels at the beginning of the study in oscillation and waves? (ii) To what levels do PhET interactive simulation-based learning impact students’ motivation and achievement in oscillations and waves? (iii) Is the change in post-test scores due to the students’ characteristics in non-randomized settings or the PhET interactive simulation-based learning? A sample of 280 (44.6% females) form three secondary school students with a mean age of 17.5 ( SD = 1.424) from four schools in Blantyre urban district in Malawi was used in a quasi-experimental design of non-equivalent groups. The experimental group was exposed to PhET simulation-based learning, while the conventional teaching methods were used in the control group. Pre- and post-tests were used to collect data on academic achievement, and questionnaires collected data on motivation. Independent samples t -test showed a statistical difference between the two groups on post-test of the academic achievement. Results from linear regression indicated that the differences between the two groups in the post-test were not due to students’ characteristics but rather the intervention with p < 0.01 . The ANCOVA test on motivation constructs showed a significant difference with a small effect size between the study groups on self-efficacy, active learning strategies, performance goals, achievement goals, learning environment stimulation, and attitudes towards learning with computer learning. The results from the study suggest that PhET simulation-based learning improved the learning of oscillations and waves. PhET simulation-based learning provides visualizations and teaching aids that help easily understand content knowledge, hence improving students’ academic achievement and motivation levels.

Physics E-Module Development Based on Contextual Teaching and Learning on Reflection of Light and Refraction of Light

“…The added value of our e-modules is that they are rich in dynamic images, animations, and visuals. where images, dynamic visuals, animations, and simulations activate the visual system in the human body, increase one's capacity to store more information, and improve cognitive processes (Banda & Nzabahimana 2022). The use of good animation and visuals in the e-module is expected to be able to assist teachers in teaching reflection and refraction materials.…”

Assessment of pre-service physics teachers’ conceptual understanding in electricity and magnetism

“…In order to use their knowledge in daily life, students must be able to grasp the concept clearly (Wörner et al, 2022;National Research Council, 2006). Technology integration in physics instruction as a whole is one strategy being used to enhance students' conceptual understanding of the subject (Gunawan et al, 2018;Banda & Nzabahimana, 2022). Teachers should have a deep conceptual understanding of physics concepts being taught in order to be able to teach their students well.…”

Logistic Regression Analysis: Predicting the Effect of Critical Thinking and Experience Active Learning Models on Academic Performance

“…However, studies on PBL, SBL, and critical thinking have not naturally evolved based on the experiences of undergraduate students. For example, research on PBL and SBL models is often carried out through special treatment in experimental classes and compared with control classes or pre-to-post tests (Banda & Nzabahimana, 2023;Crowl et al, 2022;Darmuki et al, 2023;Koparan, 2022;Sigit et al, 2022;Usmeldi & Amini, 2022). Additionally, in the context of critical thinking, previous researchers (D 'Alessio et al, 2019;de Bie et al, 2015;Demirhan et al, 2011;van Laar et al, 2019) have highlighted that these skills enable students to generate arguments, make inductions and deductions, draw conclusions, and render judgments based on gathered information.…”
