The Measuring Energy Literacy: Validation of Knowledge, Attitude, and Behavior Instruments Using the Rasch Model

2025-08-18T00:06:47+07:00

Purpose of the study: This study aims to develop and validate a Rasch Model-based energy knowledge, attitude, and behavior assessment instrument to measure energy literacy among high school students.

Methodology: The research design followed the stages of theory-based instrument development and the Rasch modeling approach. The quantitative approach and instrument development process were carried out through the stages of item preparation based on literature review and theoretical indicators, validation by experts, and field testing of 50 participants.

Main Findings: The knowledge instrument has high quality, obtained as much as 9 data showing a fit for the Rasch model, such as MNSQ infit and outfit values ranging from 0.84 to 1.25. and positive point measure correlations. Instrument reliability shows infit and outfit results that are still within the ideal tolerance range, obtained sequentially the person reliability values of knowledge, attitude, and behavior of 0.50, 0.76 and 0.75. So that the instrument is suitable for accurate and consistent measurement.

Novelty/Originality of this study: this study provides innovation in the energy literacy measurement literature (knowledge, attitude, and behavior) with an in-depth evaluation of item performance and respondent ability distribution using empirical and applicable methods for the development of evidence-based and Rasch model-based assessment instruments.

Development of Powtoon-Assisted Learning Media to Improve Students' Critical Thinking Skills in Science Subjects

2025-08-18T00:06:45+07:00

Purpose of the study: This study aims to develop Powtoon-assisted learning media to improve critical thinking skills among eighth-grade science subjects at Junior High School 1 BPR Ranau Tengah.

Methodology: This qualitative study uses Powtoon software to design instructional media. Data were collected using interview guides, observation sheets, and documentation. Miles and Huberman's interactive model was applied to the data analysis. Primary data were collected through field interviews and classroom observations; Secondary data is obtained from books, journals, and online sources.

Main Findings: Powtoon-assisted learning media significantly increased student engagement, understanding, and motivation in science learning. Students exhibit better critical thinking skills, especially in analyzing, evaluating, and articulating ideas logically. Teachers reported increased student participation and enthusiasm. Despite technical challenges such as internet access and device limitations, the overall response to Powtoon media was positive and indicated a significant improvement in learning effectiveness.

Novelty/Originality of this Study: This study introduces Powtoon as an innovative tool specifically applied to enhance critical thinking in science at the junior high school level. Unlike previous research that focused on general understanding or motivation, this study highlights Powtoon's role in developing high-level thinking. It contributes to the practice of digital education by bridging animation-based media with the development of cognitive skills.
