Concept-heavy courses such as Biochemistry in life and physical science curricula are challenging for many college-aged students. It is easy for students to disengage in a lecture and not learn the subject matter while in class. To improve student learning and participation, we employed a flipped format for the first half of the course and…

Visual-spatial literacy is an essential component to developing STEM literacy, which is a primary focus of the three-dimensional Next Generation Science Standards (NGSS) framework for science education. Because scientific data is frequently communicated through visual representations, it is important for members of the current science and…

In this randomized control study, we evaluated science teachers' pedagogical practices via classroom observations following ongoing, intensive, and structured instructional support sessions. These sessions included virtual professional development (VPD) and virtual mentoring and coaching (VMC) that accompanied a literacy-infused science…

Organic electrosynthesis is an increasingly popular tool for driving and probing redox reactions. Recent advances in this field often employ an electrocatalyst to enhance the selectivity and efficiency of electrochemical reactions. A laboratory experiment was developed to introduce students to relevant mechanistic techniques in electrochemistry…

Analogies are useful tools for teaching difficult scientific concepts and clearing up learners' misconceptions. However, if not properly used, they can lead to further misconceptions. More importantly, little is known about how science teachers use analogies in Nigerian classrooms. This study assessed science teachers' use of analogies by…

The aim of this study is to reveal experienced primary school teachers' pedagogical content knowledge (PCK), sub-components of PCK, and their possible interactions with science teaching. To this aim, a multiple holistic case study design was used. The research used a comprehensive PCK model consisting of 5 categories and 28 subcategories to…

The recent Next Generation Science Standards recommend students have increased opportunities engaging in modeling work scientists do. Science classroom tasks include simple inquiry compared to more complex authentic inquiry that closely resembles authentic science. Science fair participation presents students with the opportunity to engage in…

In the study, it is aimed to examine the relationship between science fiction self-efficacy and spatial ability of science teacher candidates. The study is quantitative research and correlation research was used as a research design. The study group consisting of 200 science teacher candidates was formed by using the convenience sampling method.…

Modeling an inter-ring torsional profile of a simple2,2'-bithiophenemolecule has been used to illustrate the main concepts associated with basic molecular modeling within an introductory course in a master's degree on computational modeling. The methodology proposed in the activity has been used to guide and train the student along the classical…

The purpose of this study was to find out the influence of the integration sequence of interactive simulation on the construction of the scientific explanation of buffer solutions. This study was conducted with 30 pre-service science teachers. The control group was randomly assigned to study with lecture first and then interactive simulation-based…

There has been a growing awareness that STEM education should incorporate a wide range of capabilities, in addition to providing traditional theoretical and practical knowledge. In line with these skills, entitled "professional skills," GTIIT has defined seven core competencies. The enhancement of two of these competencies, namely,…

Estimation of soil texture is an essential skill for soil scientists, but a difficult skill to learn. We compared two approaches for teaching soil texture: the traditional flowchart approach and an experimental self-calibration method. Three lab sections of an introductory soil science class were assigned to learn by the flowchart method (n = 60)…

The distinction between pressure in a liquid and in a gas is often treated in a cursory way, or not treated at all, even in university level textbooks. Most texts fail to point out the relation between pressure and density in a gas as compared to pressure in a--virtually incompressible--liquid. In many instances this also results in a dismissive…

Analogies are bridges between prior knowledge and new knowledge to make meaning of the new one. Analogies are particularly effective in teaching science concepts that are not very apparent in the students' everyday lives due to their abstract nature. For this reason, it is essential to adapt analogies to teach new concepts effectively in science…

Global climate change (GCC) presents unprecedented global concerns, notably food supply limitations, unsustainable use of natural resources, and widespread environmental degradation. The International Panel on Climate Change (IPCC) reports a 0.85 °C increase in global average temperatures between 1880 and 2018 and a 50% increase in global carbon…
