Molecular Cell Biology (MCB) should be taught according to the scientific practices, avoiding cumulative and memory knowledge construction, but favoring scientific thinking. A way to achieve this goal is to apply activities involving scientific news, which construct knowledge through significant learning and the development of critical thinking.…

Knowledge of science content and the ability to translate knowledge into effective teaching is known as teachers' "content knowledge for teaching" (CKT). Teachers with developed CKT are able to more effectively determine instructional and assessment activities that will deepen K-12 students' scientific literacy. However, preservice…

The initial learning experience is a critical opportunity to support conceptual understanding of abstract STEM concepts. Although hands-on activities and physical three-dimensional models are beneficial, they are seldom utilized and are replaced increasingly by digital simulations and laboratory exercises presented on touchscreen tablet computers.…

Course-based undergraduate research experiences (CUREs) provide students with valuable opportunities to engage in research in a classroom setting, expanding access to research opportunities for undergraduates, fostering inclusive research and learning environments, and bridging the gap between the research and education communities. While…

This paper aims to investigate the systematic use of an inquiry-based learning approach in science by using inquiry boxes for preschool children. We prepared four thematic inquiry boxes for the areas of magnetism and buoyancy, separation of substances, weighing objects, and the investigation of substances. The research sample consisted of twenty…

Despite the recognized link between scientific reasoning, mental sets, and conceptual change, the cognitive mechanisms underlying successful conceptual change remain unclear. To explore this, we developed computer-based reasoning programs with and without mental set support to examine their effects on conceptual change in tasks of varying…

Glycosylation is a biologically significant post-translational modification (PTM) of proteins that involves the covalent attachment of a sugar molecule (a glycan) to a peptide sequence, resulting in the formation of glycoproteins. Glycomics and glycoproteomics involve the complete mapping of glycans of a cell, tissue, or organism.…

This study investigates the cognitive processes of novice students in science learning, with a specific focus on how inhibitory control is employed to overcome a common student misconception about the buoyant force in liquid, which leads to the belief that "the greater the depth an object is in a liquid, the greater the buoyant force it…

The year 2019 was proclaimed the year of astronomy literacy by the European Astronomical Union (EAU). Several countries around the world have now started to focus more on space and astronomy endeavours and have shaped their curriculum as a result. Therefore, the perceptions and views of secondary school pupils taking social studies courses on…

This study analyzes the effect of different instructions on threshold concepts within material covering natural selection on students' use of concepts about evolution. Moreover, it examines students' use of concepts as interconnected networks when reasoning about natural selection and analyzes how these concepts relate to each other regarding…

The rapid shift to remote instruction during the COVID-19 pandemic required widespread adoption of synchronous virtual modalities such as Zoom in higher education. This study directly compares student conceptual learning outcomes in two parallel sections of an introductory physics course--one taught face-to-face (F2F) and the other synchronously…

Understanding neuroscience can provide a more effective educational approach based on neuroscientific discoveries. In this paper, we present the results of a continuing professional development course for schoolteachers on neuroscience applied to education, focusing on adolescent learning. One of the key outcomes of the course was improving…

Molecular genetics is often one of the most challenging subjects for students in biology courses. Identifying misconceptions on this subject will help teachers improve teaching and increase student success. Based on this thought, this study aimed to determine students' misconceptions about molecular genetics using a four-tier test. The researcher…

Drawing from a review of literature that has explored the history of scientific racism, this article considers how understanding the history of race, as an 18th- and 19th-century invention of Western Europe and the United States, can enhance Canadian anti-racist teacher education. I begin with a review of key conceptual building blocks of race --…

It began in 1869, and today we have 118 elements listed in the Periodic table, thanks to Mendeleev's work. Carbon, hydrogen, oxygen, and nitrogen are elements presented in many organic compounds. Some of them can exhibit photophysical and photochemical properties. Herein, we proposed an easy to make an experiment in chemistry classes to connect…
