Development of TPACK-Based Teaching Materials on Biodiversity Subject to Measure Students’ Critical Thinking Skills

/in /by

Teaching materials are auxiliary elements employed to accomplish the goals of the educational process. The observed fact reveals a deficiency in teaching materials that incorporate Technological Pedagogical Content Knowledge (TPACK) for the purpose of developing students’ critical thinking abilities. Thus, there is a want for an instructional resource that may assist pupils in enhancing their critical thinking abilities. The objective of this project is to provide TPACK-based teaching materials on biodiversity that are credible, effective, and practical. In addition to elucidating students’ critical thinking abilities through the utilization of TPACK-based instructional resources. The methodology employed in this study is Research and Development (R&D) utilizing the ADDIE paradigm. The tool employed is a questionnaire sheet for the purpose of validating materials and media. The study yielded data indicating that teaching materials centered around Technological Pedagogical Content Knowledge (TPACK) were valid and appropriate for learning purposes in the context of Biodiversity. The validity includes a material validation score of 91.25% and a media score of 96.42%, with an N-Gain of 0.75, indicating strong testing performance. Therefore, it can be inferred that educational resources rooted in Technological Pedagogical Content Knowledge (TPACK) and focused on the topic of Biodiversity have a positive impact on students’ ability to think critically.

Developing the Geometry Teaching Module by Using a Metacognitive Approach in Kurikulum Merdeka to Improve the Students’ Critical Thinking Skills

/in /by

This research aims to solve the problem of students’ critical thinking skills to follow instructions in solving mathematical problems. Students are often unaware of what they do, why they do it, and do not even know what they are supposed to do with the assignment. Meanwhile, to be a good problem solver, someone must develop good metacognition skills. By having metacognitive awareness, students are trained to solve mathematical problems through the stages of planning, monitoring, controlling and evaluating. The method used in the research is Research and Development with the model developed by Thiagarajan, Semmel & Semmel (4-D). The data collection was based on the pre-test and post-test scores in the experimental and control groups to measure the students’ critical thinking skills. The result of the post-test in the students’ critical thinking skills by using ANOVA test with significance level in 0.016 (< 0.05) shows that there was significant difference of teaching module with metacognitive approach in the material about circle within Kurikulum Merdeka to the students’ critical thinking skills.

Development of Interactive Video Learning Media Based on Articulate Storyline to Improve Students Critical Thinking Skills in Thematic Learning Grade V Elementary School

/in /by

The purpose of this study is to find out and analyze the needs of teachers and students in developing interactive video learning media based on articulate storyline to improve students’ critical thinking skills in decent grade V elementary school thematic learning. Data collection was obtained through interviews with grade V teachers and field observations. Researchers obtained information based on observations made that the critical thinking skills of grade V students of SDN 3 Bumi Nabung Timur with a percentage of 58.88%. Based on observations made by researchers, obstacles were found in the implementation of teaching and learning, namely the lack of use of learning media that supports learning. The conclusion of the learning media research has met the criteria of being very feasible. used in research. The product has met practical criteria taken from the results of educator and student response questionnaires. The practicality of the product can be seen from the activities of students in using interactive video media based on articulate storyline. The effectiveness of the product taken from comparing the improvement of students’ critical thinking skills in both samples, namely the experimental class and the control class. Based on the results of the recapitulation, it is proven that the experimental class gets an effect size value of 1.50 in the large category.

Development of A Higher-Order Thinking Skills (HOTS) Instrument to Measure Student’s Critical Thinking Abilities in Class V Elementary School

/in /by

This research and development aims to produce a feasible and practical Higher Order Thinking Skills (HOTS) instrument to measure students’ critical thinking skills in grade V elementary school mathematics subjects. This research method is development research that refers to the design of Borg & Gall. The research was conduct in class V SDN 3 Sumberejo. Feasibility testing of instruments developed in this study uses expert tests, validity tests, reliability tests, differentiation power tests and difficulty tests. The results of this study showed that an eight-question instrument was obtained, which is suitable for use. The practicality of the instrument, based on the response of educators and learners as practitioners, yielded a very practical assessment. This demonstrates that the developed HOTS instrument is feasible and practical for measuring the critical thinking ability of fifth-grade elementary school students.

Discovery Learning: Learning Modules to Improve the Critical Thinking Skills of Grade IV Elementary School Students

/in /by

This research aims to develop discovery-based learning modules on Natural Sciences and Social Sciences (IPAS) subjects in elementary schools. Research and development uses the Brog and Gall (2003) model which consists of 3 main steps of research and development. In product development, researchers use the ADDIE development model to develop prototypes of learning modules. This research was conducted in the central part of Lampung Province, precisely at SD Negeri 5 Lempuyangan Regency, Bandar Way Pengubuan. The sampling technique uses random sampling by assigning 2 classes as subjets, namely the experimental class and the control class consisting of 25 students in each class. The results of this study showed that the average score of the experimental class was 77.83 and the control class was 69.43. Based on the results of the analysis, it was found that the experimental class was superior to the control class and had a significance value obtained through the t-test before 0.000, which means that there is a significant average difference. The results are then continued on the effect size test to see the magnitude of the influence of the product used. The effect size test result is 0.83 with a very high interpretation. Based on the results of research conducted in class IV, it can be concluded that discovery-based learning modules are effective in improving students’ critical thinking skills.

Development E-Assessment Literacy Oriented Higher Order Thinking Skills (HOTS) on Thematic Learning to Measure Critical Thinking Skills of Primary School Students

/in /by

This research aims to develop E-Assessment Literacy Oriented Higher Order Thinking Skills (HOTS) which is expected to be able to measure students’ critical thinking skills. This research uses research methods according to ADDIE with five stages, namely Analisys, Design, Development, Implementation, Evaluation. The sampling technique used in this research is saturated sampling, the population of this study was class V students at SDN Berundung. The sample in this research was class V A students at SDN Berundung. The research results include the feasibility, practicality and effectiveness of the product. Product feasibility seen from the product validation results is classified as very valid, the language aspect shows an average of 0.800. The media aspect shows an average of 0.875. The test instrument was also validated by the validator as the research product showed an average of 0.650. The practicality of the product can be seen from the average percentage of educators’ responses of 90% with very practical interpretations, while student responses were 90% with very practical interpretations. The effectiveness of the product can be seen based on trial data carried out in class V of SDN Berundung. The research results prove that class V A is at stage post-test has the highest value of 90 and the lowest value of 80 with an average value of 84.58, and a standard deviation of 2.93. This shows that there is a significant influence on measuring critical thinking skills using E-Assessment literacy oriented HOTS.
