Abstract

This research aims to explain the level of misconception experienced by students identified by the Four-Tier Diagnostic Test based on the JotForm for each subconcept of heat and heat transfer. The subject of this research were students of class XI MIPA 1 and MIPA 2 with a total of 78 students as respondents. The research method uses a qualitative descriptive research type. The research instrument is in the form Four-Tier Diagnostic Test questions using JotForm. Data collection techniques through shared links are then carried out by respondents with the help of Google Meet to monitor respondents and through interviews. The results of data acquisition are interpreted using an interpretation table and calculate the percentage of each category. Based on the results of the overall data acquisition, it shows that students in class one experience misconceptions in the moderate level category, while in the class other in the law level category. The highest percentage of misconceptions for each subconcept of heat and heat transfer experienced by students is in the concept of temperature. The data from this research can be used as a source of information regarding misconceptions that occur in heat material and heat transfer that need to be addressed in order to reduce the potential for misconceptions and efforts to overcome them.

Abstract

During the Physics learning processes, students often have difficulty in understanding the concepts so that misconceptions occur. This is what was found in the Light Wave concepts when the Authors did the pre-research at one high school in Nganjuk. For example in Light Diffraction, students assumed that light diffraction be able to bending when it passes through all slit size, does not produce interference, and new waves. The truth is, diffraction in Light Wave occurs when light bends through a small slit and is characterized by interference and a new wave pattern. The misconceptions that occur in the Light Wave have the potential to hinder students' understanding of the following concepts, so they must be detected immediately. This article intends to report the results of writing the five-step conception diagnostic test on the Light Wave concepts, examine its feasibility, and then use it to map students' understanding concepts, as well as to identify the most dominant internal factors that lead students' misconceptions. Based on the feasibility test results, ten valid and reliable questions were selected so they can be used to test students' conceptions. The details are: the internal validity 96% (very valid), the external content validity consists of Correct Fake and Incorrect Fake scores are 3.3% and 4.5% (<10%) respectively, the construct external validity (rxy)=0.416>rtable=0.2638, and the reliability (r11)=0.796 (very reliable). Of the 19 students that were mapped using this feasible diagnostic test, 61.05% of them experienced a lack of knowledge.

Abstract

Throughout the COVID-19 pandemic, it is hoped that all elements of education can still facilitate learning so that children remain active even though they are online. The Indonesian policy of the government in dealing with the spread of the COVID-19 outbreak is to prevent it by imposing social distancing. This policy impacts all lives, Education is one of them., especially in the online learning process. Physics is one of the specialization subjects given to high school students. The purpose of this research is to determine impact of online learning Physics on student learning outcomes and the things that affect this impact. This type of research is a mixed-method—qualitative data obtained by observation, documentation, and interview techniques. Quantitative data comes from evaluating student achievement before the application of online learning (before the pandemic) and after the implementation of online learning (during the pandemic). Participants in this quantitative study were 116 students, and qualitative participants were 5 students' parents. The result of this study is that there is a significant impact or difference between the effects of learning Physics before and after the pandemic. This can be seen from the effects of Pillai's trace, Wilks lambda, Hoteling's trace, and Roy's most enormous root test results stating that the significance value at 0.000 is smaller than 0.05. It can also be seen from the average before the pandemic, 80,04 and after the pandemic, 82.11 This is caused by that there is excessive parental participation in completing each student's task at home.

Abstract

The main problem in this research is the low ability of students to solve physics problems. Students' attitudes and approaches to problem-solving are allegedly related to the way they study physics and their success in solving physics problems. This study demonstrated student attitudes and approaches to solving physics problems using Attitudes and Approaches to Problem Solving (AAPS) survey questions using quantitative methods. Data were collected from 1045 students. Data analysis was carried out by grouping the data by gender and education level. The t-test was used to see the differences in each group. The result showed no statistically significant differences between men and women (t = -1,65 dan Sig. = 0,098 > 0,05). In addition, there was a significant difference in the level of education between collect students with junior and senior high school education levels (p < 0.05). The implications for practice, and the directions for future research are discussed.

Abstract

This study aimed to analyze the level of senior high school students’ creative thinking skills in the line movement topic. This type of research was expost facto research. Subjects in this study were 28 senior high shcool students in one of the South Sulawesi schools. The research instrument used was a test in the essay question form. The results of this research showed that the average score of creative thinking skills was medium category with a percentage of 61%. The study results showed that the most prominent indicator was elaborate thinking with an average score of 15.93 and the lowest indicator was thinking fluently with an average score of 11.14 compared to other indicators. From the results of the study, it was concluded that the creative thinking skills of students were in the medium category. There was a suggestion that the next researcher can continue with creative thinking skills test questions with other materials. In addition, further research can also be carried out by providing innovative learning that trains creative thinking skills so that students are able to develop their creative thinking skills.

Abstract

All physics education student must take Basic Electronics courses at Siliwangi University. The course teaches students how to create electronic components. Due to the Covid-19 pandemic, the unprecedented shift from classroom learning to online learning has profoundly impacted levels of students’ learning motivation and learning outcomes in introductory electronics course online laboratory activities. The quantitative descriptive method research was conducted to analyze the implementation of the Circuit Wizard application on students’ learning motivation and learning outcomes in the introductory electronics course on the logic gate topic. Students who had recently completed the logic gate simulation were asked to write up a simulation results report. The report was used to measure students' learning outcomes. At the same time, an online questionnaire was administered to measure students’ motivation. Data were collected from 46 students of physics education (fifth and seventh semesters, the academic year 2021/2022). The results revealed students' motivation was as follows: 45% were in the good category, 27% were in a low category, and 28% were a low motivation. Findings also revealed student learning outcomes identified: 35% got an A grade, 33% got a B grade, and 4% got a C grade. These findings suggested that the implementation of Circuit Wizard in basic electronics courses positively impacted students’ learning motivation and learning outcomes.
