Abstract

This study aims to describe the theoretical and empirical validity of a science literacy-based critical thinking test instrument on the topic of renewable energy. The developed instrument integrates science literacy competencies to measure critical thinking skills while simultaneously fostering students’ science literacy within a single instrument. The instrument development followed the ADDIE model, focusing on three main stages: Analysis, Design, and Development. The instrument consists of 20 open-ended items based on Facione’s critical thinking indicators, integrated with science literacy competencies. Theoretical validity was obtained through a validation sheet reviewed by three expert validators in their respective fields, while empirical validity was obtained through a pilot test involving 34 students. The results of theoretical validity for the content, construct, and language aspects were 97%, 94%, and 90%, respectively, with an overall average of 94%, categorized as highly valid. Regarding empirical validity, all test items were deemed valid, with 14 items (70%) categorized as very high and 6 items (30%) categorized as high, and they exhibited a very high level of reliability. Based on difficulty level, 11 items (55%) were categorized as moderate and 9 items (45%) as easy. The discriminant validity analysis showed that 17 items (85%) were classified as adequate and 3 items (15%) as good. Overall, all items deemed valid can be used to measure students’ critical thinking skills in a comprehensive and structured manner.

Abstract

Indonesia's Education Report 2023 provides data showing that students' literacy and numeracy skills met the moderate criteria. The evaluation results indicate a persistent lack of understanding and unsynchronized implementation of numeracy literacy in classroom assessments. This has an impact on the less-than-optimal provision of numeracy literacy to students. This service aims to hone teachers' ability to develop science-physics numeracy literacy assessments and lesson plans. The mentoring method uses 3 meeting sessions, both offline and online, and yields positive responses from participants. The results of the activity evaluation showed a positive change in the understanding of numeracy literacy and the ability to develop assessments. The conclusion of this activity is that the mentoring carried out can contribute significantly to high school science-physics teachers' planning of numeracy and literacy assessments and learning.
