Abstract

This study aims to create an integrated assessment instrument for environmental science literacy focused on thermodynamics for high school students. The research methodology employed is Research and Development (R&D), specifically using the 4-D model. Participants in the study included 34 twelfth-grade students from Public High School 1 Palangka Raya. The validity of the instrument was evaluated using Aiken's index with input from five expert validators, while its quality was analyzed through the Rasch Model. The findings indicate that the instrument demonstrates unidimensionality, with a Raw Variance Explained by Measures value of 43.2%, confirming its effectiveness in assessing the desired aspects of science literacy. Out of the 16 items analyzed, 13 were considered fitting. The instrument also showed exceptionally high reliability, boasting a Cronbach's Alpha value of 0.89, and most items exhibited no gender bias, according to the Differential Item Functioning (DIF) test. This instrument's development is anticipated to assist students in connecting scientific concepts to real-world scenarios, enhance their science literacy skills, and raise awareness of the importance of environmental conservation, particularly regarding peatland preservation in Palangka Raya.

Abstract

The low level of scientific literacy in Indonesia is an important issue that must be addressed. One of the contributing factors is the lack of reliable and valid scientific literacy measurement tools. This study aims to analyze the dimensions and indicators used in developing scientific literacy measurement tools in science learning. The method used is a systematic literature review by collecting and reviewing 18 related research articles in the last 10 years. The results of the analysis show that most studies refer to the PISA framework which includes dimensions of explaining scientific phenomena, designing and evaluating research, and interpreting data and evidence scientifically. The integration of peatlands as a potential learning environment can be an innovative way to improve students' scientific literacy skills.
