В процессе подготовки будущих учителей физики основное внимание следует уделять не передаче суммы готовых знаний, а знакомству обучающихся с методами научного познания окружающего мира, постановке проблем, требующих от учащихся самостоятельной деятельности по их разрешению. В процессе обучения в первую очередь следует обратить внимание на то, что физика – наука экспериментальная, но при переходе к познанию микромира и мегамира снижается возможность реализации экспериментальной деятельности обучающихся. Авторами предлагается один из способов практического решения этой проблемы, заключающийся в организации и проведении лабораторных занятий с использованием разработанной виртуальной версии лабораторных работ по квантовой физике, способствующей развитию профессиональных компетенций будущего учителя физики. Также в статье рассматривается использование разработанного авторами методического комплекса «Цифровые лабораторные работы при изучении школьного курса физики», который представляет собой лабораторные работы с использованием реального оборудования с цифровыми датчиками, сигнал с которых обрабатывается на компьютере. В состав комплекса включены учебно-методические материалы для подготовки, выполнения и защиты лабораторных работ. Для достижения цели авторы использовали следующие методы исследования: теоретический анализ состояния проблемы на основе изучения методической, дидактической, психологической и специальной литературы, диссертационных работ по проблеме исследования; материалов конференций по использованию цифровых технологий в физическом образовании, нормативных документов, определяющих структуру и содержание профессиональной подготовки учителя физики, изучение и обобщение педагогического опыта; компьютерное моделирование физических процессов, наблюдение, беседа, анкетирование, интервьюирование, проведение педагогического эксперимента. In the process of training future physics teachers, the main attention should be paid not to transfer the amount of ready-made knowledge, but to familiarize students with the methods of scientific knowledge of the world around them, and to pose problems that require students to independently solve them. In the course of training, first of all, you should pay attention to the fact that physics is an experimental science, but when you move to the knowledge of the microcosm and mega world, the possibility of implementing students’ experimental activities decreases. The authors suggest one of the ways to solve this problem in practice, which is to organize and conduct laboratory classes using the developed virtual version of laboratory works on quantum physics, which contributes to the development of professional competencies of future physics teachers. The article also discusses the use of the methodological complex developed by the authors "Digital laboratory work in the study of school physics", which is a laboratory work using real equipment with digital sensors, the signal from which is processed on a computer. To achieve this goal, the authors used the following research methods: theoretical analysis of the state of the problem based on the study of methodological, didactic, psychological and special literature, dissertation works on the problem of research; materials of conferences on the use of digital technologies in physical education, normative documents that determine the structure and content of professional training of physics teachers, the study and generalization of pedagogical experience; computer modeling of physical processes, observation, conversation, questioning, interviewing, conducting a pedagogical experiment.

AbstractIdentity-based research in physics education has been receiving increased attention in the past few years given the potential of identity in producing novel insights into the ways’ students engage in physics. In this study, we examined the development of preservice physics teachers’ physics identity through a specific instructional practice: a specially designed course incorporating the use of the multiple representations. Although specific programs and instructional practices have been found to influence the development of physics identity, there is no clear evidence about the kinds of instructional practices that might support its development. To examine the influence of multiple representations on each component of physics identity, we designed and implemented a physics course that used a multiple representation (MR)-based instructional approach with a group of 61 preservice physics teachers at a public university in Indonesia. Data were collected with a pre- and post-questionnaire on physics identity, a conceptual understanding test, and a post-test that examined differences between identity components before and after the course, conceptual understandings, as well as the participants’ views about the use of the MR-based instructional approach. The findings revealed a significant improvement of two components of physics identity, namely, competence and interest, and point to the potential of MR-based instruction in physics courses.

Physics education essentially intends to cultivate student’s analytical and reasoning capabilities. However, this objective is hard to achieve because there are many students who facing difficulties in solving physics problems. This research was conducted to identify the types of student’s difficulties in solving momentum and impulse problems, along with the factors causing it. This research was conducted using a descriptive qualitative approach to 66 students of Senior High School 2 Makassar who had studied momentum and impulse topics. The data collection process was carried out using test and interviews. Based on the results, it can be identified that there are two types of student’s difficulties in solving momentum and impulse problems. The first type was physical difficulties which consisted of student’s difficulty in understanding the questions (26%) and student’s difficulty in determining the useable equations (25%). Then, the second type was mathematical difficulties which consisted of student’s difficulty in substituting the data to the equation (63%) and student’s difficulty in performing mathematical operations (76%). Based on interviews and analysis, it can be concluded that these difficulties was commonly faced by students while solving physics problems, including in momentum and impulse topic. Futhermore, the difiiculties were caused by several factors, namely: 1) the lack of student’s understanding about physics concepts, 2) the weakness of student’s mathematical skills, 3) the lack of physics learning process which is not honing student’s problem-solving skills and  4) the lack of student’s motivation on developing their problems solving skills in physics subjects. Thus, researchers recommend to all physics teachers in Indonesia to immediately develop or implement learning strategies or methods which are considered capable of overcome all student’s difficulties that have been found.

The electromagnetism is one of the important topics in physics and it has quite a lot of applications in a wide range of area. It also examines the electromagnetic force researches that occur between the electrically charged particles. On the other hand, examination of the magnetic field around the conductors and the movement of the charged particles in the electromagnetic field is quite interesting topics on that the physics researchers intensively investigated. The electromagnetic theory has an abstract nature, because the university level students have many learning and understanding difficulties about the concepts related to these topics. In realization of meaningful learning, the role of the students’ prior knowledge about the aforementioned concepts is becoming important. This study aims to investigate the understanding of 12 pre-service physics teachers related to the concept of moving particles in an electromagnetic filed by using the qualitative research methods. The data collected through the test consisting of three question and it was analysed by using content analysis method. The understanding levels and the alternative conceptions of the pre-service physics teachers were determined by different categories at the end of the content analyses process.   Keywords: Alternative conceptions, electromagnetism education, pre-service physics teachers; understanding level;

Physics education possesses great potential in providing an outstanding opportunity to drive and shape sustainable development for the future world. Perhaps, the subject is among the science subjects that are better learned through laboratory experiments. Practical physics work enables students to do experiments on the fundamental laws and principles and gain experience of using a variety of measuring instruments and other physics-related apparatus. However, insinuation suggests that most students show less commitment to practical work, attributed to various factors. Thus, the purpose of the present study was to examine internet addiction as a factor that could explain the variation in students participation in physics practical. One hundred and forty-four students who met the inclusion criteria were selected from secondary schools in the Kogi state as the participants. The respondents completed a self-report measure of internet addiction and practical physics participation. The result revealed that compulsive internet usage significantly predicts participation in physics practical. Thus, the study concluded that internet addiction is a positive determinant of students engagement in physics practical.

Abstract Reflecting in written form on one’s teaching enactments has been considered a facilitator for teachers’ professional growth in university-based preservice teacher education. Writing a structured reflection can be facilitated through external feedback. However, researchers noted that feedback in preservice teacher education often relies on holistic, rather than more content-based, analytic feedback because educators oftentimes lack resources (e.g., time) to provide more analytic feedback. To overcome this impediment to feedback for written reflection, advances in computer technology can be of use. Hence, this study sought to utilize techniques of natural language processing and machine learning to train a computer-based classifier that classifies preservice physics teachers’ written reflections on their teaching enactments in a German university teacher education program. To do so, a reflection model was adapted to physics education. It was then tested to what extent the computer-based classifier could accurately classify the elements of the reflection model in segments of preservice physics teachers’ written reflections. Multinomial logistic regression using word count as a predictor was found to yield acceptable average human-computer agreement (F1-score on held-out test dataset of 0.56) so that it might fuel further development towards an automated feedback tool that supplements existing holistic feedback for written reflections with data-based, analytic feedback.
