Abstract

This research aims to develop and determine the validity, practicality, and effectiveness of Eco-STEM based E- worksheet to improve scientific creativity among junior high school students in the subject of substances and their changes. The background of this research is based on the lack of interactive, contextual teaching materials and the lack of learning that emphasizes scientific creativity and environmental issues. In addition, there is also a lack of utilization of digital media in learning. This research uses the ADDIE development model. The research subjects were 26 students in class VII A MTsN 2 Jember in the odd semester of the 2025/2026 academic year. Its validity was classified as very high based on expert evaluations of content accuracy, language clarity, presentation quality, and graphical design in alignment with the curriculum. The practicality results indicated an average score of 94% (very practical category), demonstrating that the E-worksheet can be implemented smoothly and consistently with the planned learning activities. Its effectiveness in improving students’ scientific creativity was reflected in the average N-gain value of 0.60 (moderate category), indicating meaningful improvement in students’ scientific creativity abilities. In addition, students’ responses yielded an average score of 92.1% (excellent category), highlighting positive perceptions of the E-Worksheet in terms of visual appeal, ease of use, and overall usefulness. In conclusion, Eco-STEM based e-worksheet is suitable for use as an innovative teaching material to improve students' scientific creativity

Abstract

 The level of scientific creativity among Indonesian junior high school students remains relatively low, partly due to the limited scope of school based assessment instruments that fail to comprehensively measure this competency, particularly in the context of environmental sustainability and STEM integration. This study aims to develop an eco-STEM based scientific creativity assessment instrument on the topics of temperature, heat, and expansion for seventh grade junior high school students, as well as to determine its quality in terms of validity, reliability, discriminative power, difficulty level, and practicality. This study employed a modified Borg and Gall model consisting of nine stages. The research subjects included expert validators, science teachers, observers, and seventh grade students at SMP Negeri 12 Jember. Data were collected through validation sheets, a practicality questionnaire, and a test instrument comprising 28 open-ended items. Data analysis included content validity (Aiken’s V), item validity (Pearson correlation), reliability (Cronbach’s alpha), discriminant validity, difficulty level, and practicality percentage. The results showed that the instrument met validity criteria with a percentage of 76–79%. All 28 items were declared valid with calculated r values (0.703–0.945) > table r. The instrument’s reliability was very high with a Cronbach’s alpha of 0.990. The discriminative power falls into the adequate category (0.255–0.389). The distribution of difficulty levels is close to ideal (25% easy, 36% moderate, 39% difficult). The practicality score is 86.7% (highly practical). This assessment instrument is suitable for science teachers to use in evaluating students’ scientific creativity in a comprehensive and contextual manner
