Abstract

Assessment plays an important role in measuring the achievement of 21st-century skills, particularly reading literacy, numeracy, and critical thinking. However, assessment practices that remain focused on rote memorization have not fully captured these skills in an integrated manner. In addition, the integration of local cultural contexts into science assessments is still limited. Therefore, this study aims to develop a reading literacy and numeracy assessment instrument incorporating West Java ethnoscience contexts on the topic of thermochemistry that is appropriate for assessing students’ critical thinking skills in terms of content validity. This study employed a test design and development method involving five chemistry education experts as validators. The resulting product consists of 50 reading literacy and numeracy items that incorporate nine ethnoscience contexts in West Java: torch parade tradition, bandrek preparation, Kampung Kuta palm sugar, adu kuluwung tradition, peuyeum Bandung, biogas in Cibodas village, Kampung Naga traditional house, maranggi satay, and bathing around kawah rengganis.  The results of the content validity indicate that all texts and test items were considered highly valid (CVR = 1; I-CVI = 1; S-CVI/ave = 1). These findings suggest that the alignment among chemistry concepts, reading texts, and test items has been adequately achieved. The validated instrument was then designed within a learning management system, namely moodle, as a digital-based trial medium and to support further improvement of the instrument quality during subsequent testing stages

Abstract

Measuring students' critical thinking skills (CTS) on the topic of solubility and solubility product constant (Ksp) is currently still hampered by the limited assessment instruments that are capable of evaluating the reasoning process authentically and comprehensively. This research aimed to develop an e-portfolio assessment tool on solubility and Ksp subject matter that can help enhance CTS of students. Two assessment instruments have been developed, namely tasks and rubrics. This research used research & development methods and followed the 4-D model, but consisting of define, design, and develop phases only, with limited trials. Research instruments used as data collection tools are interview guidelines, validation sheets, observation sheets, tasks, and rubrics. Respondent of this research was 20 students coming from class XI of one of the high schools located in Bandung city. Functions designed as an e-portfolio assessment tool on solubility and Ksp subject matter have successfully been developed through mind mapping, essay analysis questions, and experimental reports of students. Results have ascertained that research instrument is valid, based on CVR value range, namely, 0.60-1.00, and could be considered reliable as indicated by Cronbach's alpha reliability of value range, namely 0.62-0.93. Based on limited trials, students demonstrated moderate improvement in CTS in most tasks. Only three questions showed significant improvement. Of the nine CTS indicators, most were in the moderate category. Only one indicator, observing research results, was in the high category. However, these results indicate a positive impact of using the instrument on improving CTS. Based on the results, this research has ascertained that e-portfolio assessment tool on solubility and Ksp can help enhance CTS of students on moderate category
