In physics education, a number of studies have developed assessments of teachers' knowledge of student understanding (KSU) of specific physics concepts with modified versions of existing concept inventories, in which teachers were asked to predict the popular incorrect answers from students. The results provide useful but indirect information to…

Developing a deeper understanding of scientific concepts is one of the primary goals of science education. To improve students' conceptual understanding, it is necessary to explore the major characteristics of their learning process. Informed by previous work on conceptual understanding, this study focuses on the concept of evaporation, exploring…

Physics problem-solving ability is among the crucial skills physics students require as it enhances their conceptual understanding and develops their abilities for real-world problem-solving. This study employed a descriptive design to investigate the physics problem-solving skills of Senior-Five physics students from Rwandan secondary schools.…

This research explores the effect of mental model-based learning on understanding school chemistry. The learning activity included group discussion, presentation and class discussion. Pre-service chemistry teachers (PCT) analyzed school chemistry topics in relation to essential underlying concepts. The development of mental models was monitored…

Electricity and magnetism are fundamental areas of physics and are integral to science curricula at various educational levels. However, this area has been reported to contain several concepts that students find challenging, leading to perspectives that diverge from scientifically accepted views. This study examines the errors made by physics…

Although there has been extensive research on students' understanding of the particulate nature of matter (PNM), there is still a lack of research on contexts that can be used to teach this challenging topic. In a previous design-based research study, the authors developed a teaching-learning sequence (TLS) on the PNM in the context of crystal…

The study investigates secondary students' understanding of "orbital" and "electron cloud" concepts in different quantum contexts (for values of the ?principal quantum number n = 1 and n = 2) on the basis of their verbal and pictorial representations, evaluating also their consistency. Participants, which were 192 12th-grade…

This study investigated the role of interactivity on the protégé effect, and explored how biology teachers can utilize it in their classrooms to reduce rote learning and facilitate long-term retention. This investigation utilized the generative learning theory, and adopted a non-equivalent quasi- experimental research design involving 60 students.…

The purpose of this study is twofold: (1) to develop and validate a three-tier diagnostic test on work, power, and energy (WPE) concepts and (2) to identify Turkish pre-service science teachers' conceptual understanding through this test. The Work, Power, and Energy Concept Test (WPECT) was developed through interviews, read-aloud sessions, and…

This study aims to reconstruct Grade 11 students' misconceptions about force through the Conceptual Change Model (CCM) making use of Predict, Discuss, Explain, Observe, Discuss, Explore, Explain (PDEODEE) tasks. This study was conducted using a mixedmethod approach. The participants in this study were 65 students (33 students in the experiment…

In this paper, we explored the scientific literacy of a general sample of the Slovak adult population and examined factors that might help or inhibit scientific reasoning, namely the content of the problems. In doing so, we also verified the assumption that when faced with real-life scientific problems, people do not necessarily apply…

Learning about the Earth through geoscience education is important in order to make informed decisions about the future of the Earth. The aim of this study is to examine students' conceptual development on geoscience subjects based on inquiry-based learning. 7th grade students participated in this study. The researcher prepared lesson plans and…

This study aimed to develop a two-tier light concept test to identify student concept understanding of light. The development of the test was carried out through the content validity, construct validity, and reliability test stages using the Item Response Theory (IRT). The sample consisted of 81 students during the second semester at five…

The COVID-19 pandemic caused severe disruption to education in the UK in 2020, with most of the school teaching moving online and national school examinations being cancelled. This was particularly disruptive for those taking end of school examinations in preparation for higher education. Biological science courses require students to absorb a lot…

This paper reports a mapping of the astronomy content knowledge held by a sample of 171 Chilean in-service teachers, both from primary and secondary education, using a multiple-choice test. The responses were analysed by total achievement, and the proportion of alternative conceptions for each item was identified. Moreover, the test items were…
