In this study, an innovative scientific modeling course on concentration cells is designed: First, the demonstrations revealed examples of three different concentration cells. Then, scientific models visualizing the process and principle of cell reactions at the level of microparticulates were introduced to students. Finally, three new…

Understanding ongoing chemical processes in the laboratory requires constant shifting between different representational levels--the macroscopic, submicroscopic, and symbolic levels--and analysis of the various mechanistic features of each of these levels. Thus, the ability to explain observations of chemical phenomena with regard to their…

Rarely are scientific phenomena isolated to a single discipline such as biology, chemistry, physics, Earth science, or others. Rather, these phenomena span multiple disciplines and often require bringing together content and understandings from multiple disciplines to engage with or explain the target phenomena. This study uses a model-based…

This study examined middle school students' scientific reasoning ability in relation to gender and learning environment perceptions. The data were obtained from 269 (148 girls and 121 boys) students. A two-tier multiple-choice test was used to assess students' scientific reasoning ability, while a Likert scale-type self-report questionnaire was…

The presented research focuses on verifying the confluent application of concept mapping (CM) and socio-scientific issues (SSI) according to the value-laden and moral dilemma orientation to construct problem-solving performance. This research sets up some perspectives for all 146 participants, including 139 students and 7 experts. All findings…

In March of 2020, the world of education was upended. Teachers and students across the globe abruptly left their classrooms. Once taught in abstraction, science concepts became national headlines, no longer relegated to textbooks. Misinformation began spreading faster than any virus, and for many science teachers, addressing scientific untruths…

This study investigates if collaboration and the level of heterogeneity between collaborating partners' problem-solving scripts can influence the extent to which pre-service teachers engage in evidence-based reasoning when analyzing and solving pedagogical problem cases. We operationalized evidence-based reasoning through its content and process…

Careful consideration of the design of an online laboratory course can lead to an improved laboratory experience for students (Cancilla & Albon, 2008). This dissertation study represents one iteration in a process to improve the online offering of a general biology lecture and laboratory course at Hartnell College. The purpose of this research…

The influence of the epistemological beliefs of parents on the development of comprehensive scientific reasoning abilities was investigated in a five-wave longitudinal study from kindergarten to elementary school. The 161 German 5-10-year-olds (89 girls, 72 boys) were assessed yearly on their scientific reasoning abilities using comprehensive…

Students are encouraged to develop a set of scientific skills and disciplinary practices common across the STEM disciplines. These skills (scientific inquiry, quantitative skills, laboratory and computational skills, communication skills, teamwork/interpersonal skills, interdisciplinary competency) are highlighted as important in discipline-based…

The history and philosophy of science course is among the very important courses for prospective teachers in terms of understanding the development of science, evaluating its social and cultural context, developing scientific thinking skills, and better understanding and teaching scientific knowledge. Studies on this subject are important in terms…

The electricity-related topics in the secondary school science curriculum are near-universal standards across countries. We prepared a three-stage robotic STEM program incorporating coding, robotic integrated science (in the topic of electricity), STEM engineering processes, and their educational structures. We investigated the impact of the…

The urgent need for teachers and students for innovative learning media that integrates local context (ethnoscience), and technology (STEM) to improve students' science process skills is the main basis for the development of this electronic module. This study aims to produce an interactive STEM ethnoscience science electronic module. The…

This study determined the influence of the competency of teachers and the laboratory environment in an online setting on the students' science process skills using mixed methods approach-convergent design. Participants of the study were 2nd year students from different Higher Education Institutions in Region XI, Philippines. Further, to gather…

Due to the increased use of scientific models and modelling in K-12 education, there is a need to uncover its effects on students over time. Prior research has shown that the use of scientific modelling in K-12 classes is associated with improved conceptual knowledge and problem-solving skills. However, few studies have explicitly tested the…
