Abstract

Indonesian students' scientific literacy scores decreased by 13 points from PISA 2018, indicating that the scientific literacy skills of participants in Indonesia are low. One area of concern is students' understanding of chemical equilibrium, which is essential because it is a prerequisite for grasping subsequent materials. This study aims to assess the feasibility of interactive e-worksheets as a learning medium for chemical equilibrium material in terms of validity, practicality, and effectiveness. According to Thiagarajan, the research employs the 4-D research and development model, which includes Defining, Designing, Developing, and Disseminating but is limited to the development stage. A limited trial was conducted using a one-group pretest-posttest research design. Validation results show that the interactive e-worksheet is valid with a mode value of 4 in content, presentation, language, and design. The validity test results yielded a mode value 4 for both content and construct validity. The practicality test results indicated a high percentage of practicality with very practical criteria. The effectiveness test, analysed using n-gain, showed an n-gain value of 0.78 with high criteria, and the paired sample t-test results indicated a P-value of 0.000, confirming that the post-test scores were significantly higher than the pretest scores. Thus, the PBL-oriented Interactive e-worksheet can improve students' scientific literacy skills.

Abstract

The science literacy skills of Indonesian students are still low based on the results of PISA 2022. Chemical equilibrium material is very important, and understanding chemical equilibrium is a prerequisite for understanding subsequent materials. One of the efforts to improve understanding of chemical equilibrium material is applying a student-centred learning model, the PBL model. PBL can also improve students' science literacy skills. Thus, research was conducted to develop PBL-oriented interactive electronic student activity sheets on chemical equilibrium material to improve students' science literacy skills. This research aims to describe the effectiveness of interactive E-LAPD as a learning media for improving students' science literacy skills. Research and development (Research and Development) is the type of research used.  The research design used in this research is the 4-D model development research design according to Thiagarajan's 4-D model, which consists of the define, design, develop, and disseminate stages. The instrument used in this research is a pretest and posttest sheet of science literacy skills to measure students' science literacy skills. This research used a limited trial with a one-group pretest-posttest research design. The limited trial was conducted at SMAN 1 Kedamean with 36 class XI MIPA 3 students. The effectiveness results analyzed using the paired sample t-test obtained a p-value of 0.000, which indicates that the posttest value after learning using interactive E-LAPD is greater than the pretest value before learning using interactive E-LAPD. Thus, PBL-oriented Interactive E-LAPD can be said to improve students' science literacy skills.
