Development of Problem-Based Kinematics Teaching Material to Improve Students' Critical Thinking Skills
Get PDFPhysics learning needs to be given by giving problems so that students can gain experience from their thinking abilities. Student's mindset will be more focused if they are able to think critically. The purpose of this study was to develop problem-based teaching material to improve informatics engineering students' critical thinking skills. With this teaching material development, students are expected to be able to maximize their thinking skills. This study used development research design that aimed to produce a problem-based physics teaching material. The trial subjects for this teaching materials were 3 lecturers and 12 informatics engineering students from University of PGRI Madiun. From this study, quantitative and qualitative data were obtained. The obtained data from the assessment of lecturers and students will be analyzed by average analysis technique.

A Development Design of Digital Story Conceptual Change-Oriented in Physics Subject
Get PDFThe result of need analysis shown that are difficulties still exist for teachers and students if they are learning in the new condition immediately. Therefore, this study aims to provide learning tools in the digital form and called as digital story conceptual change oriented (DSCC). This research was research and development by using ADDIE (analysis, design, development, implementation, and evaluation) design. This media tested the small scale test. The product designed on the subject of physics (Heat and Temperature) was validated by experts and tested on 147 respondents from Junior High School in West Singkawang and Central Singkawang sub-disctrict. The developed design was measured based on Learning Aspect (LA) which consists of: 1) Contextual problems, 2) Solution / Answer to the problem, 3) Communication effectiveness. The results of small-scale product trials shown that the Problem Solution aspect got the highest percentage of 93% and the communication aspect becomes the lowest with 73% while also having the worst responses with a percentage of 10%. This study could be references for researchers to improve the product to be better media and it could be so that it can be used directly and produce good learning outcomes
Physics Achievement Test Implies Students’ Self-Efficacy on Decision Making Process
Get PDFThis research was conducted to provide a comprehensive description about how the results of the cognitive learning outcomes of the physics field were indirectly supported by self-efficacy in the decision making process of the beliefs of the chosen answers. This research is descriptive qualitative research and involves 24 samples of class X students. The sample technique chosen was purposive sampling. The testing of cognitive learning outcomes in cognitive domains was conducted and designed by physics education lecturers and self-efficacy testing carried out and designed by lecturers in the direction of guidance and counseling using attitude scales. This combination of measurements produces two decisions on self-efficacy: positive and negative. The results of the study showed that students with high self-efficacy got high scores also on the physics test of cognitive learning outcomes. These students are classified as students with positive self-efficacy. Conversely, negative self-efficacy shows that students have high self-efficacy but get low cognitive test results in cognitive domains. These results are certainly influenced by several factors including uncertainty and anxiety
Analysis of Vocational School Students' Ability in Conceptual Understanding
Get PDFThe purpose of this study was to analyze the ability of vocational students in understanding the concept of Rotational Dynamics. This study used qualitative methods with 10 respondents consisting of high, medium and low categories. Instruments in this study used essay test with 6 questions and interview. The results of this study showed that students' conceptual understanding in rotational dynamics was low. Students were still having difficulties in understanding the concept of Rotational Dynamics, namely in determining angular velocity, inertia moment equation, and solving equations. Then it is better to understand the concept needs to be applied in the learning process. So it can be concluded that conceptual understanding approach needs to be applied in the learning process
