Based on the pedagogical principle of cognitive conflict, Inquiry-Based Laboratory Activities (IBLAs) have been shown to improve conceptual understanding of challenging science and engineering topics. Yet, providing students physical apparatuses to complete an IBLA is not tenable in every instructional setting. This paper reports design,…

This article reports on the development and piloting of a German version of a concept test to assess students' conceptual knowledge of density. The concept test was administered in paper-pencil format to 222 German secondary school students as a post-test after instruction in all relevant concepts of density. We provide a psychometric…

In recent years, more and more systematic research has been conducted in science fields, focusing on identifying alternative ideas that the students have for essential concepts and principles of physics. This has resulted in the production of essential and valuable international bibliographic information in various science fields, including…

This study investigated the factors influencing students' performance in science subjects at different schools in a school district in the midland area of South Carolina. For the convenience of the study and to maintain confidentiality, the school district is named Midland School District 2022. The population of this study included students in…

The work in this dissertation is presented in two parts. The first part (Chapters 3 and 4) details work relating to students' explanations of reaction mechanisms in organic chemistry. The second part (Chapters 5 and 6) details work relating to the evaluating the uptake of research-based instructional practices in introductory chemistry,…

Research in the field of physics teaching has revealed high school students' difficulties in establishing relations between kinematic equations and real movements. Moreover, there are well-known and significant challenges in their comprehension of graphic language content. Thus, this article explores a didactic activity which utilized robotics in…

Problems of optimization in natural science, technology, economics, and management are of great interest. Students also usually find them intriguing. However, the selection of such problems in introductory undegraduate physics textbooks is very limited and should be broadened. To that end, a model of traffic flow optimization, simple enough for…

The aim of this study is to compare the master's (MA) theses in Türkiye (TR) and Finland (FIN) published between 2015-2019. A total of 765 theses were analysed in terms of year, discipline, methodological approach, research method, didactic foci, data collection tool, target group, and sample size. The results showed that FIN theses grounded on…

This work explores the integration of artificial intelligence (AI) custom chatbots in educational settings, with a particular focus on their applicability in the context of mathematics and physics. In view of the increasing deployment of AI tools such as ChatGPT in educational contexts, the present study explores their potential in generating…

Mindset (beliefs about the malleability of intelligence) has been studied in a variety of contexts for decades. Recent research highlights the importance of contextual factors in moderating mindset's impact on student outcomes. The commonly-used original mindset measure is context-general. Recently, a mindset measure that is specific to science…

The research reveals the problem of training human resources in society using digital technologies. The current level of development of the labor force is closely related to the change in the improvement of the technical basis of production activities. The role of a teacher is considered, which is defined as a highly qualified teacher who seeks to…

The motion of a bead along a path restricted to straight lines (restricted brachistochrone), sliding without friction from rest and accelerated by gravity, is considered. For two shapes of path, the geometry of the route optimized to provide the least travel time from one point to another is obtained. The bead's travel times, path lengths, and…

Physics education researchers (PER) commonly use complete-case analysis to address missing data. For complete-case analysis, researchers discard all data from any student who is missing any data. Despite its frequent use, no PER article we reviewed that used complete-case analysis provided evidence that the data met the assumption of missing…

The notion of quantitative physics education research (PER) so far has been mostly limited to the mere use of statistical methods or use of computational tools for analyzing numerical data. Little attention, in fact, has been given to the underpinnings of this research paradigm. To fill the gap, this theoretical paper addresses key and yet often…

An easy operating tool has been developed for the quick measurement of thermoelectric power. The setup is made using a tweezer which consists of two circular copper plate electrodes. These copper electrodes are fixed to two arms of the tweezer which act as hot and cold probes. The setup has the very important advantage of easy sample mounting and…
