This lesson focuses specifically on teaching concepts of speed and its impact on energy, as well as providing a basic introduction to potential and kinetic energy to fourth-grade students. "Next Generation Science Standards" ("NGSS") 4-PS3-1 states that students should be able "to use evidence to construct an explanation…

The modeling of rates of biochemical reactions--fluxes--in metabolic networks is widely used for both basic biological research and biotechnological applications. A number of different modeling methods have been developed to estimate and predict fluxes, including kinetic and constraint-based (Metabolic Flux Analysis and flux balance analysis)…

With the implementation of Next Generation Science Standards, educators shifted from lecturer to facilitator using inquiry-based learning approaches. Teachers may express anxiety about this role reversal in providing scientific instruction. This study addressed conflicting perspectives in the implementation of inquiry-based learning approaches as…

Learning needs to be well planned so that it can take place in accordance with the objectives to be achieved. This planning can be poured into the learning implementation plan (RPP) prepared by the teacher. Therefore, this study aims to describe the competence of prospective chemistry teacher students to prepare lesson plans using a scientific…

This autoethnographic study is part of a funded project involving a school science teacher and university science education researchers. In this project, we incorporated nature of science (NOS) into the fifth-grade curriculum and implemented it for a semester at a public school in Turkey. We adopted Reconceptualized Family Resemblance Approach to…

While recent research has examined students' and teachers' understanding of models and modeling, few studies have focused on how teacher educators can support preservice elementary science teachers in envisioning enriched learning processes and outcomes for their students while engaging in modeling practices. Informed by reflective practices…

The use of data to explain natural phenomena has been a core feature of science education, and science educators continue to call for an increased emphasis on teaching data practices. This mixed methods design-based research study adds to the growing body of research on data practices in science by explaining the learning trends of science…

With the onset of COVID-19, colleges and universities moved to emergency remote teaching, and instructors immediately adjusted their curricula. Many instructors adapted or developed new online lessons that they subsequently published as Open Educational Resources (OERs). While much has been examined related to how entire course designs evolved…

ChatGPT holds significant potential for enhancing learning through integration into education as an advanced chatbot. With the goal of harnessing this potential, our research focused on exploring the utilization of ChatGPT in designing a course plan for pre-service science teachers. We adopted a qualitative research approach and employed ChatGPT…

Many physics learners take the specific mathematical representations they are using as part of their learning and doing physics for granted. The paper addresses this problem by highlighting two goals. The first is to show how a historical investigation from history of science can be transformed into a concrete lesson plan in physics, in a physics…

Developing student capacity for the science, technology, engineering, and math (STEM) workforce requires not only better preparation in specific content and skills but also better preparation in understanding the goals that STEM fields can afford. In particular, stereotypic views that STEM fields lack communal opportunities to work with and help…

This study took 'context' as a focal point in the context-based approach and its investigation was anchored on an analytical framework, which is composed of three dimensions of context: origins, intentions, and occasions. Content analysis was employed as the research methodology with 878 contexts identified from 96 copies of awarded chemistry…

Animals depend on their surroundings for their survival. In consuming their food, animals are consuming energy. This cycling of matter and the accompanying flow of energy within an ecosystem occurs because of interactions among and between organisms. To guide students in modeling how ecosystems function, the authors share "Ecosystem…

This qualitative action research study examines how middle and high school STEM teachers create and implement lessons that connect concepts to the real-world and develop student metacognition. The researcher collected data through interviews, focus groups, document analysis, and survey questions. Participants from vocational, private, and…

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…
