Background: Recognizing the relatively few studies that have explored university students' understanding and alternative conceptions in linear and circular motion as well as the relatively few studies that have used 2-dimensional multiple-choice questions (MCQs) in the science education literature, this study set out to contribute to these areas.…

The learners' conceptual understanding has become one of the leading research areas conducted by educational researchers. Both students and current educators should actively work to improve their understanding of alternative conceptions and deepen their conceptual knowledge. One of the essential concepts in chemistry learning is colligative…

This study aims to develop and validate a Constructivist Learning Environment Model to address secondary students' misconceptions in learning Science. Employing a Design and Development approach (Richey & Klein, 2007), the research is conducted in two phases. Phase 1 focuses on model design, drawing from an extensive literature review to…

Evaluating evidence and restructuring beliefs based on anomalous evidence are fundamental aspects of scientific reasoning. These skills can be challenging for both children and adults, especially in domains where they possess inaccurate prior beliefs that can interfere with the acquisition of correct scientific information (e.g., heavier objects…

This research investigated the effect of project-based learning (PjBL) on students' conceptual understanding of mechanics. For this purpose, a quasi-experimental research design was conducted with 50 ninth-grade students at Nazarbayev Intellectual School in Kazakhstan. We used the force concept inventory test to measure students' conceptual…

In science, one of the most crucial representations for constructing meaning about physical events is graphs. The first graph students encounter in science class is the constant velocity motion graph. Therefore, examining students' understanding of structuring and interpreting these graphs for the relationship between distance, time, and velocity…

A central objective of science education is to foster a profound comprehension of fundamental scientific principles among students. Research has shown that a highly integrated knowledge structure is a key factor in achieving a deep understanding. This research has developed a friction force conceptual framework to model students' different…

Contemporary secondary science education is characterised by a greater inclination towards the constructivist paradigm of education and the development of inquiry-oriented teaching. The basic principle of this paradigm is the dynamic modification of preconceptions towards the desired level given by the school curriculum. This places particular…

Electrophilic aromatic substitution (S[subscript E]Ar) and nucleophilic aromatic substitution (S[subscript N]Ar) reactions are among the most valuable reactions in the conversion of aromatic rings. While these reactions are typically covered in separate experiments in undergraduate organic courses, a continuous experimental setup elucidating both…

The importance of genetic diversity, especially within small populations of endangered species, is becoming increasingly apparent. Genetic engineering techniques that could potentially enhance diversity are now being developed. However, the use of such techniques would require social licence and yet within the general population there is limited…

This study examines the effects of the pedagogical use of context-rich problems on motivation and learning, as compared to traditional problems, in mechanical physics courses at the college level. The results indicate that the treatment has appreciable outcomes on conceptual learning gain, on the perception of task value and on a perceived sense…

Many science students struggle with using scientific language and making sense of scientific phenomena. Thus, there is an increased interest in science education research and public policy with regard to understanding and promoting scientific language use and sensemaking in science classrooms. However, there is a lack of comparative studies on how…

We present two studies to investigate the extent to which attending a planetarium presentation increases secondary school students' understanding of the apparent motion of the Sun and stars. In the first study, we used the Apparent Motion of Sun and Stars (AMoSS) test in a pretest/post-test/retention test setting to measure learning gains and…

This study investigates the influence of inquiry-based laboratory activities on the understanding of heat concepts and the self-efficacy beliefs of pre-service primary teachers. Recognizing that both scientific literacy and teaching efficacy are critical for effective science education, this research aims to determine how inquiry-based laboratory…

This study used a case study, one of the qualitative research methods, with the aim of developing guidance materials based on the argumentation-based science learning (ABSL) approach for concepts in the 6th grade unit "Sound and Its Properties" and to examine students' argumentation levels and conceptual understanding. The activity…
