Background: The importance of diagnostic and scaffolding activities for early science learning has been shown consistently. However, preschool teachers scarcely engage in them. We developed an instrument to assess preschool teachers' willingness to engage in diagnostic and scaffolding activities in science learning situations and examined its…

Assessments are an integral part of academic environments and can present opportunities for students to make sense of novel contexts using their existing ideas. Assessments also provide insights on students' learning and the efficacy of the pedagogical practices. Consequently, physics education research shares a storied history of developing…

Students in a typical instrumental analysis course may learn more than 30 analytical techniques. There are more than 150 components associated with the instrumentation that they learn. To help students organize this large amount of information, we classified these components into four categories: sources, samples, discriminators, and detectors. In…

Collaborative learning methods are increasing in popularity as a way of improving student performance and involvement in undergraduate courses. For this study, a group quiz format was used in an attempt to improve course grades and engagement in an introductory meat science course. Six group quizzes and six individual quizzes were taken by 70…

Since the appearance of the COVID-19 pandemic and its subsequent stage, the changes produced in the chemistry teaching process have allowed educators to use a wide range of strategies, methodologies, and tools to promote student learning. To carry out laboratory practices, some strategies reported include the use of simulators and educational…

Excessive alcohol consumption in adolescence is a worldwide concern because of its numerous negative consequences. It also increases the chance of accidents and may lead to significant impairment of part of the brain, causing learning difficulties. The present work aims to present the development of a forensic educational kit composed of a…

Primary literature searching and the utility of research articles in chemistry teaching and instructions provide connections between conceptual understanding and the application of chemical knowledge. Article citation tracking, an often-neglected dimension in literature exploration, expands information seeking and provides opportunities to track…

There is a considerable amount of research on the nature and effectiveness of modeling as applied to student learning in science. However, few studies have examined the role of students' epistemic uncertainty in modeling and how teachers collaborate with students to recognize and utilize it as a pedagogical resource to support productive struggle…

The obstacles and difficulties that science teachers face when teaching the nature of science (NOS) are well-known. Nonetheless, little is known of what science teacher educators (STEs) know, do, and think about this issue. Thus, a study with 142 Spanish STEs was conducted. This was aimed at analysing (i) what preparation the STEs have to teach…

Students' understanding of forces in circular motion is often incomplete. The problems are not limited to confusions about centripetal acceleration and centrifugal forces. This paper considers possible effects of different interventions by a teacher who has discovered the many types of free-body diagrams drawn by students for circular motion in a…

The aim of this study was to analyze the development of the PCK of a Chemistry student teacher, from a university in southern Brazil, during teaching activities in the Supervised Internship. The theoretical basis adopted in this study was the PCK theory proposed by Shulman (1986, 1987) and some models that unfolded from it. Data collection…

The aim of this study is to conduct a meta-analysis study to examine the effectiveness of the argumentation-based teaching method in terms of sample, subject, years and some variables (academic success, attitude, interest, etc.). Meta-analysis method was used in this study. In order to gather the studies included in meta-analysis, various sources…

This exploratory case study affirmed the merit of using science fiction-inspired story writing to help Saudi Arabian Grade 10 female students learn science. Recognizing that teacher-centered rote learning was not reaching her rural students in the western part of Riyadh Province, the female teacher in this case switched to the constructivist…

Dynamic assessment (DA) seeks to understand learners' abilities that are still developing by embedding mediation (i.e., contingent forms of assistance) into the assessment process. To date, DA studies have been carried out primarily in contexts focused on language learning. However, in content classrooms (e.g., science, math), English learners…

Researchers have typically identified and characterized teachers' knowledge bases (e.g., pedagogical content knowledge and subject matter knowledge) in an effort to improve enacted instructional strategies. As shown by the Refined Consensus Model (RCM), understanding teacher learning, beliefs, and practices is predicated on the interconnections of…
