Abstract

Critical thinking is one of the skills students must possess in the 2013 curriculum, especially in 21st-century learning. Indonesia's low ranking in PISA results in the critical thinking category, ranked 64 out of 65 countries is important from this study. The low thinking skills of students are caused by students' critical thinking skills in science learning are still not optimal. Based on observations made by researchers in the learning process, teaching materials use more books so that learning does not run interactively. This leads to students' critical thinking skills being poorly trained. This research aims to develop teaching materials in the form of project-based learning emodules that improve the critical thinking skills of grade 5 elementary school students effectively. The development method in this study uses a 4-D model from Thiagarajan (1974), namely Define, Design, Development, and Dessimination. The instruments used in this study were interviews, questionnaires, and observations. The results of this study showed that the project-based learning e-module was valid with material validation results of 75.6%, media validation results of 84.5%, and language validation results of 81.25%. In addition, student responses from individual trials were 97%, in small group trials by 90%, and in large group trials by 87%. Quantitative analysis with independent sample t-test using SPSS 26 for Windows showed that there was an average difference in final observation results between the experimental class and the control class of 2.625 with a sig (2tailed) p-value of 0.000. These results were obtained from the responses of experimental and control class students. Thus it can be concluded that the use of e-modules in learning has improved students' critical thinking.

Abstract

The understanding of molecular form materials requires a high level of visual spatial skills, but most high school students still show low visual intelligence since the content is abstract and there isn't any interactive digital media. The goal of this project is to enhance students' visual intelligence regarding the submaterial of molecular shapes by creating 3D-assisted e-worksheets that are integrated with the Think Pair Share (TPS) paradigm. The 4D model (define, design, develop) is used in this development research. involving 35 students in grades XI-3 of SMA Hang Tuah 1 Surabaya and three expert validators. Data was collected through validation sheets, response questionnaires, activity observation sheets, and visual intelligence pretest-posttests including four indicators: imagination, conception, problem solving, and pattern search. The results showed that the e-worksheets were declared valid with all ≥ 4 medians, practical with 96.43% student responses and 99.4% activity implementation, and effective according to the Wilcoxon Signed-Rank test (Z = −5.165, p = 0.000) with an average increase of 56.90 points and all students experienced an increase in scores. The highest increase occurred in the pattern search indicator (64.24 percentage points). 3D-assisted electronic worksheets integrated with TPS have proven to be effective in bridging abstract molecular representations with students' visual intelligence, so they can be an alternative learning medium for abstract chemistry materials at the high school level.
