In this work, we present the results of a research in which we aimed to evidence obstacles and advances in pre-service teachers’ conceptualization on a subject involving elementary Quantum Mechanics. We based our analysis on the theories due to David Ausubel and Gèrard Vergnaud to study Meaningful Learning patterns, both in predicative and operatory form of knowledge, of six students involved in a didactical intervention composed of six classes, in which we emphasized both similarities and differences between Classical and Quantum Physics. With this intervention, we intended to teach the concepts of Physical System, Dynamical Variables, State of a Physical System and Time Evolution. We guided our data analysis by the methodology of content analysis (Bardin, 2008) and it turned possible to map Meaningful Learning patterns involving the four concepts to which were associated a set of essential features (in the predicative stage) and a set of theorems-in-action (in the operatory stage) relating the aim-concepts in problem-solving or conceptual mapping.

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.

Argumentation and knowledge justification have been noted as important skills to be learned in secondary and tertiary level of education. These skills are especially crucial in teaching and learning physics because physics knowledge is normative and has hierarchical structure. The purpose of this article is two-fold. First, we propose a framework to analyze pre-service physics teachers’ knowledge justification. Second, we show how this framework can be used to examine pre-service physics teachers’ knowledge justification in the context of quantum physics. The sample consists of 68 knowledge justification schemes on four quantum phenomena (N=17 participants who all produced four schemes). The proposed framework discusses conceptual, relational and strategic knowledge presented in knowledge justification schemes. The results show that analysis framework reveal significant differences between pre-service teachers’ knowledge justification. We conclude that there is need and room for such practical tools, which help future teachers to organize and consider their own knowledge.

Many recent studies have reported that feedback plays a very important role in students’ learning outcomes. However, currently, feedback has not been utilized by lecturers and students in the learning process effectively. This study aimed to explore the impact of feedback as a soft scaffolding in the ongoing assessment of Quantum Physics class for the students as prospective Physics teachers. A quasi-experimental design non-equivalent pretest-posttest control group was used to examine the effectiveness of feedback based on ongoing assessment. The results of the study revealed that students who received feedback based on metacognitive and social constructivism on studying Quantum Physics showed better average results compared to students who received traditional feedback based on the cognitivism in the form of correction.

The aim of this study is to identify the opinions of pre-service physics teachers about the difficulties in introductory quantum physics topics. In this study conducted with twenty-five pre-service physics teachers, the case study method was used. The participants were interviewed about introductory quantum physics topics. The interviews were coded using content analysis and were divided into different categories. In this way, we tried to reveal the opinions of pre-service physics teachers about the difficulties of these topics. In conclusion, it can be said that the participants had the most difficulty in transition from classical physics to quantum physics. This is especially evident in quantum physics topics that require a different understanding such as black body radiation, wave-particle structure of light and the uncertainty principle. It was also found that the participants had no difficulties in terms of mathematical calculations, and that approaches based on visualizing the topic were received positively.

Quantum physics involves counterintuitive abstract concepts and complex mathematical procedures that are difficult to understand by physics and chemistry students at university level. This study employs case study- one of the methods of qualitative study- and it aims to determine the difficulties prospective chemistry and physics teachers encounter in understanding quantum numbers. 17 students in total were included in the study. The data were collected via a test of three open-ended questions developed by the researchers. The collected data were then analysed by using the content analysis method. It was found accordingly that both prospective chemistry teachers and prospective physics teachers had difficulties in understanding quantum numbers. The findings obtained in this study were compared with the ones obtained in similar studies and were discussed accordingly.
