Abstract

This study aimed to determine the effectiveness and validity of a teaching document using Argument-Driven Inquiry (ADI) model with a Contextual Approach to improve students' critical thinking skills in science learning. This type of research was research and development (R&D) that refers to the 4D model. Data collected by the validation sheets, student response sheet, and critical thinking skills test. They were analyzed by using t-test and N-gain. The present research was applied in lower secondary at SMP Negeri 1 Bluto with trial design of One-Group Pretest-Posttest Design. The results of the data analysis show that (1) the learning materials was valid in terms of the results of the validity of the materials with the score of 3.57; (2) learning materials was effective in terms of: (a) the students' responses were categorized as very good with results of 83.2%, (b) students' critical thinking skill increased with an average value of N-gain in grade eight A of 0.74 and 0.75 for grade eight B with a high category. Based on the results of statistical analysis using the t test, the probability value (sig) was 0,000 in the two classes. This means that the significance value was less than 0.05 which means there was a significant difference between the pre-test and post-test results. In conclusion, Argument-Driven Inquiry (ADI) model with a Contextual Approach is proven to be feasible and effective for improving critical thinking skills.

Abstract

This study aims to determine the effectiveness of STEM-based guided inquiry learning on physics science literacy. This study uses a research and development (R & D) development model with a one group pretest-posttest design. The sample used was class XI students with three replications. The data collection technique is in the form of a science literacy test sheet. Then analyzed with a quantitative and qualitative descriptive approach. The research data shows that the learning model developed is theoretically valid by three expert validators. The effectiveness of learning tools is shown by the science literacy scores of students who have increased after applying the STEM-based guided inquiry learning model. Based on the discussion of the research results, it can be concluded that the learning tools developed are effectively applied in schools to train students' science literacy in sound wave material.
