The Provision of Conceptual Change Text for Reducing Students’ Misconceptions in The Physics Learning of Light During the Pandemic Covid-19
Full text linkConceptual change is seen as a powerful teaching approach for developing 21st century skills. To determine the usefulness of delivering a conceptual change text for fostering conceptual change regarding light in physics learning at home during the pandemic, a quasi-experimental design was adopted, with one group pre-and posttesting. The participants are 23 eighth-grade students from SMPN 2 Ledo Bengkayang, a public secondary school in the rural region, who were recruited using an intact group random selection technique. A diagnostic test was provided, which included nine multiple-choice items and two distractors, as well as supporting arguments. This study discovered that students' beliefs regarding light and the process of vision vary significantly. After treatment, pupils' misunderstandings were reduced by 26.80%. After receiving the CCT, students had a considerable conceptual shift, and the CCT's effectiveness was sufficient (gain mean = 0.58). To get more effective results, CCT should be used in conjunction with any other teaching approach or model. A scientific teacher should exemplify a conceptual transformation method in the classroom

Full text linkThe learning process that uses learning models and approaches that involve the active role of students can improve students' abilities. This study aims to analyze the effectiveness of the physics e-book PBL model with a STEMI approach to improve students’ problem-solving abilities in terms of gender. In this quantitative study, a one group pretest-posttest approach was used. The research sample used was 55 class XI students of MA Hidayatullah Mataram, of which 25 were male students and 30 were female students. Collecting data on the effectiveness of using the problem-solving ability description instrument which consists of eight questions. Effectiveness data analysis used the N-Gain test and Rash model analysis. The results showed that male students dominated the IPSA-1 indicator (89.06) and IPSA-2 (68.23), while female students were more dominant in the IPSA-3 (89.19), IPSA-4 (76.35), and IPSA-5 (71.35). The results also showed that female students in all sub-subjects of work and energy had a higher average score than male students. In general, the results of the study also show that the PBL model physics e-book with the STEMI approach used in the learning process is effective in increasing the PSA of male and female students with an N-Gain score of 70.04

Full text linkThis research aims to exploring and reconstructing of indigenous knowledge of coffee processing in Kerinci into scientific knowledge. This research was qualitative using ethnoscience approach. The research was carried out at Coffee Nur Kerinci. The key informan were the owner and employees of Coffee Nur. Data collection was carried out through observation and deep interview. Qualitative data were analyzed descriptively using the Miles and Huberman models. The processing of Coffee Nur Kerinci carried out traditionally using simple tools. It consists of drying of coffee beans, roasting, cooling, pulverization, sifting, and packaging of coffee powder. Drying of coffee beans was carried out by the sun for 21 days with an average of five hours/day. The roasting process was carried out by using a roaster made of a drum that rotated on the stove. The pulverization was carried out by using a waterwheel as a driving force which was connected to eight pestles. Scientifically, the processing of Coffee Nur Kerinci can be reconstructed into scientific concepts regarding the classification of living things, heat and transfer, circular motion, collisions, and forces
The Effectiveness of Educational Tools Grounded in Local Knowledge in Enhancing High School Students' Creative Thinking Skills in the Context of Sound Waves
Full text linkThe objective of this study was to describe the effectiveness of learning tools based on local wisdom in enhancing creative thinking skills in the context of sound waves. The research was conducted at SMA N 1 North Gorontalo, specifically targeting eleventh-grade students.

Validity and Practicality of the STEM-Critical Thinking Video in Science Education: Hydraulic Lift
Full text linkThis study aims to determine the validity, practicality and students' responses to video experiments oriented towards STEM activities and critical thinking. The research problem is that the implementation of experimental activities in schools is still very rarely used because, limited learning time and the learning that is carried out has not been able to train students' critical thinking skills. The research method used is Research and Development, the research design uses the Plomp model which consists of three stages, namely the preliminary stage, the prototyping stage and ends with the assessment stage, but this research is limited to the prototyping stage. The instruments used to collect data were validity sheets (26 questions), practicality sheets (18 questions) and interview sheets (5 questions). VHL was analyzed descriptively and quantitatively based on the results of validity tests, practicality tests and interviews. The results of the validity test from the three expert reviewers showed that VHL obtained a score of 0.92 with a very high validity category. In terms of practicality, the VHL scores 98% (very practical). In terms of students' responses to VHL, the majority of students stated that they were happy, interested and enthusiastic about learning to use VHL. Therefore, VHL with the theme "Hydraulic Lift" is categorized as feasible and practical to help grade 8 students in practicing critical thinking skills on the concept of material pressure

Four Tier-Relativity Diagnostic Test (4T-RDT) to Identify Student Misconception
Full text linkMisconceptions in physics lessons are still the main problem faced by teachers and students. Misconceptions of physics occur at various levels of education and many physics materials at the high school level. The results of observation to class XII students in Semarang obtained data that the material on the theory of relativity is material with a low level of mastery of concepts. In addition, teachers also have difficulty in identifying physical misconceptions experienced by students. Therefore, this study aims to develop an instrument in the form of a Four-Tier Diagnostics Test to identify students' physics misconceptions on the material of relativity theory, determine the level of validity, reliability, and characteristics of the four-tier diagnostics test. The type of research is Research and Development (R&D). The methods used are documentation, interviews, questionnaires and tests. The results showed that the instruments were valid and reliable. The diagnostic test consists of four levels, namely: a question with one answer key and four distractor, the degree of confidence of the answer, the reason, and the level of confidence of the reason. The resulting instrument consists of a grid, work instructions, test questions, answer keys, answer sheets, scoring guidelines, and result interpretation guidelines. Validity testing by expert validators shows the developed instrument is valid and reliable
