Abstract

The teacher's conception is one of the misconceptions that students encounter, so it is critical to uncover the status of the teacher's conception in order to improve the students' conception. The purpose of this study is to identify physic’s teachers misconceptions about direct current material. There were 16 Physics Teachers in one of the districts in East Java, including 7 (seven) teachers from the Public High School (Negeri) and 9 (nine) teachers from private schools (Swasta). This research is a quantitative descriptive analysis research. A three-tier diagnostic test was used to analyze the data, which revealed that the average percentage of misconceptions faced by teachers was 58% in a medium category. The results also showed that physics teachers had the highest rate of misconceptions in the Potential Difference sub-concepts (94%), while the Series Circuit concept had the lowest proportion of misconceptions (25,50%). misconceptions experienced by physics teachers must be addressed immediately, because it will have an impact on students' conceptions. The results of this study are very important for policy makers, especially the Education Office to find solutions in breaking the chain of physics misconceptions

Abstract

This study examines problem-solving as one of fundamental cognitive processes required for the 21st century skills. In this context, physics learning is generally directed to focusing on how students in schools attain this ability, which includes analyzing, evaluating, and reflecting activities to find solutions to a problem based on student’s own knowledge and experience. The aim of the current study is to determine student’s profiles on problem-solving skills at the initial stage for a given subject of electric circuits in a classroom setting. Students of Muhammadiyah 3 Vocational High School, Gresik, Indonesia specialized in electrical engineering were sampled as targetted people. The method used was a descriptive approach, where instruments for data collection were developed using Polya's steps. Research findings were derived from student performance indicators, namely understanding a given problem which scored 55.9%, planning strategy for a solution to the problem which achieved 48.7%, implementing the strategy which obtained 7.7%, and checking the solution which marked 13.85%. In conclusion, the results showed that students’ skills on problem-solving was found to be at a very low level.

Abstract

Research aims to find out misconceptions experienced by students on the subject matter of substance pressure. This type of research is quantitative descriptive research using a survey method. The instrumental test used was a three-tier diagnostic test to determine the under-examined misconceptions. The research sample consisted of 43 junior high school students who had previously received substance-pressure learning materials in class. The data were analyzed by categorizing them into understanding the concept, needing more knowledge, errors, and misconception. The results of the study were as follows: (1) 9% of the students understood the concept, 51% of the students had a misconception, 34% of the students were lack of knowledge, and 6% of the students had some errors (2) misconceptions with the highest percentage were in the sub-concept of pressure gases with an average percentage of 70%, then the pressure of liquids (capillarity and osmosis in plant stems) was 52%, the pressure of solids was 51%.

Abstract

This study aims to describe students’ critical thinking skills and the corresponding prior knowledge of Virtual Reality (VR) media used for learning purposes in a classroom setting. A total of 65 high school students from Grade XI Science 1 and Science 2 were involved as respondents in this preliminary research using qualitative-descriptive analysis. The instrument used included questionnaires (distributed over the respondents) containing 12 questions on VR relevant to the indicators of critical thinking skills. The results showed students' skills in critical thinking at the intermediate level. The indicator of analytical ability has the highest percentage in the medium category. The number of students with critical thinking skills in the high category is 14, and in the medium category, as many as 51 students. Students' prior knowledge of VR media (familiar with the technology) was reported to 46.00% of all the respondents, and the remaining 54.00% did not know what it was. However, all the respondents were interested and happy with VR media as a learning tool. Improvement of critical thinking skills could be achieved through contextual learning and VR learning media. The implication of the present study for future use of VR education media in schools is possible as VR media is considered to be technology-assisted learning, applicable to science and physics teachers when delivering learning materials in class.

Abstract

Objective: This study aims to determine the profile of problem-solving ability in junior high school students on global warming. Method: This research is preliminary. The study used a quantitative-descriptive research type and a purposive-sampling method. The instrument included a problem-solving ability test with four questions based on the Polya indicator on global warming lesson materials. The research sample consisted of 33 students from class VII-B, JHS Al-Miftah 4 Karang Anyar Ketapang Timur Sampang District East Java Province, who had previously received global warming lesson materials. The research data was analyzed by calculating the average score of the indicator student's problem-solving ability in the form of a percentage. Result: The results were as follows: the interpretation of problem-solving abilities in students is still dominant in the "Very Less" category with a score of 43%, and the overall average value of problem-solving abilities obtained based on indicators of problem-solving abilities gets of 32.25% belonging to the category "Not enough." Novelty: Analysis of problem-solving abilities can be a reference and a means of developing self-ability related to problem-solving abilities in the school environment, considering that solving abilities have yet to be highlighted too much, especially in remote areas. Problem-solving abilities are still a problem in the world of education, so further research is needed as a means to improve students' problem-solving abilities.
