Abstract

Recitation programs have been developed and tested on the topic of force and motion. The program consists of 63 multiple choice questions with feedback made in 3 packages (one package each week). This study aims to analyze the effectiveness of the program. This research is a quantitative research with a quasi-experimental design. The applied experimental design is a one group pretest-posttest design. The program was given for 3 weeks by giving 1 recitation package at each meeting (there are 21 questions for every package). The study was conducted on 38 Physics Education students’ who enrolled the Material and Learning Physics I course. The pretest-posttest questions consisted of 15 reasoned multiple-choice questions. Data analysis was performed by determining descriptive statistics, paired sample t-test, N-gain, and d-effect size. The research found that the program significantly improved students’ conceptual understanding with N-gain of 0.498 and d-effect size of 1.559. These results indicate that the provision of recitation programs can improve students' conceptual understanding on force and motion, especially in determining the F(t) graph from the v(t) graph, where initially the ability to solve problems in the form of graphical representations is one of the difficult matters for students.

Abstract

In this paper, we describe the intervention and the context of implementation of a multiple representations (MR)-based instructional approach as a classroom practice in an first-year thermodynamics course for preservice physics teachers at an Indonesian university. We argue that the implementation of this approach will contribute to the enhancement of students’ conceptual understanding and problem-solving skills. By enhancing those two aspects, we intend to contribute to their development of physics identity and physics teacher identity. We illustrate how this MR approach is applied in the classroom and describe how the relationship between the aspects of this approach interacts with physics identity and physics teacher identity. During lessons the teacher used real-life examples and students were encouraged to use different representations when they solved problems in small groups. The students realized that learning physics could involve many representations and might increase their interest to physics. However, we found some situations that did not match our expectations. For instance, most of the students were more interested when the problems were in the form of mathematical representation. In addition, we found that some students were inactive in the class. Therefore, it is necessary to think as educators about how to provide a positive learning experience to stimulate the development of student's identity. This work exemplifies how physics educators can stimulate physics and physics teacher identity formation in their physics courses as a preparation for future physics teachers.

Abstract

In undergraduate classrooms, while teaching chaos and fractals, it is taught as if there is no relation between these two. By using some non linear oscillators we demonstrate that there is a connection between chaos and fractals. By plotting the phase space diagrams of four nonlinear oscillators and using box counting method of finding the fractal dimension we established the chaotic nature of the nonlinear oscillators. The awareness that all chaotic systems are good fractals will add more insights to the concept of chaotic systems.

Abstract

This study focused on an assessment of pre-service physics teachers’ conceptual understanding of physics in the domain of electricity and magnetism concepts. The study employed a descriptive survey method of research. The study sample consisted of 100 pre-service physics teachers from five teacher education colleges during the academic year 2021/21. The study used preliminary data from a PhD dissertation that was gathered by administering a conceptual understanding test on electricity and magnetism, which contained 32 items adapted from standardized tests. The data were analyzed using descriptive statistics, one sample t-tests, independent samples t-tests, and one-way ANOVA. The results of the one sample t-test showed that the conceptual understanding test scores for electricity and magnetism were considerably below 50 and 70 which are the national standard pass mark points and the baseline for certification of competency to the teaching profession, respectively. ANOVA analysis revealed that there was a statistically significant mean difference among the pre-service physics teachers in the colleges. The post hoc test analysis showed that there was a statistically significant mean difference between pre-service teachers from two colleges. The independent samples t-test revealed that there was statistically significant mean difference between test scores of males and females in favor of male pre-service physics teachers. In addition, the participation of female candidates was too low compared to their male counterparts. In conclusion, the achievement of pre-service physics teachers was below the expected values; differences among colleges were detected; and there was an achievement and participation imbalance in relation to gender, though consecutive measures were taken. Based on the conclusions, recommendations are given that could be applicable.

Abstract

The research aims to analyze the physics PSS profile of high school students and the implementation of the AR book-assisted PBL model as a consideration in the use of media and learning models to support the high school students' PSS improvement. This is preliminary descriptive research without hypothesis testing with 154 high school students as participants. Descriptive methods of qualitative approach is employed to analyze through questionnaires and tests of assessment about PSS. This study revealed that the students’ PSS is still in the low level. This is evidenced by the students’ results of low category with a score range within 0 to 50. This study also found that students' interest in learning physics with AR (Augmented Reality) books-assisted have improved their PSS. It is concluded that the learning methods, as well as learning media, can affect students' PSS.

Abstract

The concepts of floating, flying, and sinking object have been studied since junior high school. However, we still often find students' misconceptions regarding the concept, especially of flying objects, even at the university level. This work aims to propose a clarification of the concept of a flying object in the fluid to be correctly described the condition for the flying object. We used eggs, water, and salt solutions to demonstrate sinking, rising, and floating objects in the fluids. The results showed that when the density of the object is the same as the density of the fluid, the position of the object is still at the bottom of the fluid since it was not flying in the middle of the depth of the fluid. But the object does not touch the bottom of the container so that the object's height is zero. This is because the object has not had a driving force (Fd = 0) that pushes the object upward towards the surface of the fluid to float. When the density of the fluid slightly exceeds the density of the object, the object immediately moves upward to the fluid surface - floating phenomenon is started. The greater the difference between the density of the fluid and the density of the object, the faster the object moves towards the surface. The object cannot stay at any position between the bottom and the surface of the fluid. A stable position is reached when the object reaches the surface of the fluid to float. This work is expected to increase students' understanding of flying objects in fluids.

Abstract

A simple experiment has been conducted to study Newton's law of cooling and heating by observing the nature of the increasing and decreasing water temperature by utilizing a data logger, a thermocouple, a pan, a hot plate, and water. The uncovered pan contained water which was subsequently heated on a hot plate. The water was heated at ambient temperature and normal atmospheric pressure to see that the temperature rose exponentially. Conversely, the temperature of hot water decreased exponentially when the heat source was switched off. The model for increasing and decreasing water temperature is following the Newton's law of cooling and heating. It was proven that the experimental data highly fit theoretical models. The temperature increment constant (ka) and the temperature decrement constant (kd) determined the rate of temperature changes. Low values of ka and kd led to the slow change in the temperature, either the increase or the decrease in the water temperature and vice versa. The ka > kd was observed for all given conditions so that the increasing rate in the water temperature was faster than its decrease. The result of this study can be applied as an example of contextual learning of physics for university students.

Abstract

Dieng Culture Festival (DCF) is considered as the symbol of cultural wealth owned by the local people of Wonosobo, Central Java Province, Indonesia. The reconstruction of indigenous knowledge (indigenious science) of Dieng Plateau people is hardly integrated into science learning. Meanwhile, creative thinking skills as a demand for 21st century skills are urgently needed in students' lives. One of the learning models recommended by the 2013 curriculum is the inquiry lesson model. The ILESSI-DCF (Inquiry Lesson Based Ethno Socioscientific Issues-Dieng Culture Festival) model is an inquiry model constructed with the Socioscientif Issues (SSI) strategy and an ethnoscientific approach. This study aims to analyze the contribution of the ILESSI-DCF (Confrontation, Observation, Recognition, Explanation, Application) syntax in promoting creative thinking skills. The research method used quasi-experimental with the type of independent sample t-statistical design. The research sample consisted of two MA (Madrasah Aliyah) namely MA A, totaling 60 students (experimental group 29 students, control group 31 students), and MA B totaling 64 (sixty four) students (experimental group 32 students, control group 32 students). The data collection method used creative thinking skills test questions. The data analysis technique used SPSS 25.0 on the MANOVA test to analyze the extent to which each syntax of the ILESSI-DCF Model contributed. The results showed that the overall contribution of each syntax of the ILESSI-DCF Model was effective in promoting creative thinking skills. The contribution of the ILESSI-DCF Model syntax has the greatest contribution to syntax 3, namely the reconstruction of students in MA A with a mean of 12.10 when compared to the other syntaxes, while the lowest contribution to syntax 1 Confrontation in MA B with 9.68. The results of the ILESSI-DCF Model syntax contribution very diverse and being influenced by differences in students' cultural backgrounds in reconstructing science action. The implications of research into the contribution of the ILESSI-DCF Model syntax to the ability to reconstruct people's original science into scientific knowledge is very important for realizing character education that respects diversity through the creative thinking skills of MA students.

Abstract

The purpose of this research is to find out students’ opinion about e-module ordinary differential equations that will be developed. This type of research is a mixed method with the purposive sampling technique. The samples were 50 students of Universitas Jambi majoring physics education a regular class A and regular class B 2020 who took the mathematical physics II course. The data were collected through interviews and questionnaires, then analyzed using descriptive statistics for the questionnaires and Miles and Huberman’s analysis for the interview results. The findings show that the majority of the students believe the creation of this e-module is a very good idea. This is proven by the results of descriptive statistics, where the average value is 18,0 and is in the required category. The quantitative findings are strengthened by the qualitative ones from interview, which show that the majority of respondents support the creation of this e-module. The results indicate that the students require additional learning resources to fully comprehend the lessons in the Mathematical Physics II e-module. Students can learn independently in mathematical physics course by using e-modules. The future studies on mathematical physics e-modules can use this study as a guide.
