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

The purpose of this research was to see how effective the Problem Based Learning (PBL) based Socioscientific Issues (SSI) is at improving critical thinking skills. The sample used was grade seven in SMPN 4 Lamongan with 2 classes and each class contains 15 students. The design of the learning materials trial used One-Group pre-test post-test design. Tests of critical thinking skills and student answer sheets were used to collect data. Techniques of data analysis used N-gain, paired t-test, and independent t-test. The result of this research is as follows: The effectiveness in terms of the critical thinking skills test the category increase is high, there is a significant difference between the test before and after learning with PBL based SSI and there is no difference N-gain in the two group classes and students' responses are classified as very good. Based on data analysis, it can be concluded that PBL with SSI is effective to improve critical thinking skills. The implications of this study are PBL-based SSI has the potential to be an innovative solution and alternative for improving critical thinking skills.

Abstract

This study aims to describe the profile of critical thinking based on argumentation learning in senior high school. This study used a quantitative descriptive study with a subject of 30 students. Subjects were asked to choose the correct answer based on the questionnaire and questions about critical thinking. The results from the questionnaire showed that students' critical thinking skills are 43% in the low category; 47% in the medium category, and 10% students in the high category. As evidenced by the average test results of critical thinking skills, the results obtained are 57.5 in the low category. In the indicator of formulating problems, the results obtained are 57.5 with low critical thinking categories; indicators provide arguments and analyze results 50 with low critical thinking categories; and the result deduction indicator is 60 with medium critical thinking category.Therefore, it can be recommended that the first step to improving critical thinking skills is to conduct argumentation-based learning so that students can convey arguments in physics learning and students' critical thinking skills can increase, so that it's expected to produce competent students according to 21st-century learning.

Abstract

This study's purpose is to obtain a profile of students' problem-solving skills and describe the achievement of implementing Problem-Based Learning (PBL) in high schools. The profile of problem-solving skills was obtained by giving tests and questionnaires to 53 students, while the achievement of implementing the PBL model was obtained by interviewing six students and one chemistry teacher. The research data obtained is then described. The findings revealed that the students' problem-solving skills remained low, namely in the poor and very poor categories with a percentage of 67.93%. Meanwhile, students' problem-solving skills were in the enough category at 20.75%, in the good category at 11.32%, and in the very good category were not found. This study also demonstrates that the teacher's application of learning with the PBL has yet to lead to students achieving the problem-solving skill indicators that are measured. In addition, students' prior knowledge was found to have contributed to the achievement of these indicators. This study suggests adapting and modifying the PBL model's syntax based on all present constraints to develop a new learning model capable of appropriately training students' problem-solving skills by focusing on the side of students' prior knowledge, formulation hypothesis, and reflection activities in learning.

Abstract

The Lawson Classroom Test of Scientific Reasoning (LCTSR) is a popular instrument that measures the development of students’ scientific reasoning skills. Through large-scale applications, several issues have been observed in terms of validity, scoring, and the way of interpretation. This study aims to identify the contribution and describe the research profile of applying LCTSR in education during the last ten years. The method used in this research is a bibliometric analysis based on Scopus data with the help of Biblioshiny and VOSviewer. The study obtained 43 documents related to LCTSR. The results showed that the use of LCTSR every year has increased and decreased in the last ten years. Journals and proceedings in the field of physics dominate the publication sources for LCTSR research. Furthermore, Bao, Koenig, and Xiao were the three most prolific authors and also had research collaborations. The dominant country for publication is the United States. The area most often associated with LCTSR research is social science, whose purpose is to measure the development of student’s cognitive abilities. The scope of this research analysis is limited to certain databases or languages, so this study recommends finding renewed discussions about the use of LCTSR in education over a longer period.
