A kinesthetic classroom activity was designed to help students understand enzyme activity and catalysis of reaction rate. Students served the role of enzymes by manipulating Pop-It Beads as the catalytic event. This activity illuminates the relationship between reaction rate and reaction progress by allowing students to experience first-hand the…

Students try to understand many abstract concepts by using mental models they have created by thinking and imagining. Students must have a functional and dynamic atomic model in their minds in order to understand the atomic and atomic concepts. In this study; it was aimed to determine the models of science student candidates using the analogy of…

This dissertation describes the results of an investigation into introductory student understanding of special relativity in the context of the relativity of simultaneity. The research probes the extent to which students are able to use concepts from both Galilean and special relativity to determine, for multiple reference frames, the time…

Women are underrepresented at multiple levels of physics education. One avenue for understanding the classroom experiences that perpetuate underrepresentation is physics identity, defined using the three dimensions of recognition, performance, and competence. Existing literature suggests that women tend to have a much weaker physics identity than…

Skills in science, technology, engineering, and mathematics (STEM) are increasingly in demand. Theoretical knowledge and formulas alone are frequently not sufficient to understand complex phenomena. Simulations are a valuable tool to support the conceptual understanding by visualizing invisible processes. The constant interaction with the learning…

The purpose of the study is to determine the knowledge and awareness of gifted children receiving education in the Science and Art Center on nanotechnology. The descriptive survey model was used in the study. The purposeful sampling method was chosen and a total of 160 students receiving education in two Science and Art Centers located in the city…

The purpose of this study was to investigate both the individual and relative effectiveness of two conceptual change interventions, gender and their interactions on preservice science teachers' conceptual understanding and their misconceptions in mechanical waves. The interventions are conceptual change texts enriched with concept cartoons (CCTCC)…

Perezhivanie is a concept that was originally defined by Vygotsky, but it did not become a part of educational theory until recently. Today the concept has been revived, and it is now used as a way to include emotional aspects into education and educational research. The concept also provides a rationale for describing and forming personalised…

This pilot study utilizes 360° camera and viewer technology in a science content-based EFL class at a Japanese University. Due to a lack of initial knowledge on how to best incorporate this technology into a content driven EFL class, a co-development strategy was devised between the teacher and students to dynamically design a course over…

This case study explores how a science teacher adopted knowledge building and learning analytics to support a class of primary five students to collaboratively inquire and learn about electricity. Specifically, we aim to understand how the teacher implemented a lesson design guided by knowledge building principles of idea improvement and community…

This study explores the acid-base topic in the context of a chemistry course taken as a prerequisite for a baccalaureate nursing program. Core findings were derived from semistructured interviews with experts in the areas of chemistry and nursing, and a multiple university survey of experts' opinions. The acid-base topic was reviewed and evaluated…

In this article we examine how bilingual students construe relations between everyday language and the language of science. Studies concerning bilingual students language use in science class have mainly been conducted in settings where both the teacher and the students speak the same minority language. In this study data was collected in a class…

In this study, an analysis of the structure of scientific explanations included in physics textbooks of upper secondary schools in Greece was completed. In scientific explanations for specific phenomena found in the sample textbooks, the "explanandum" is a logical consequence of the "explanans," which in all cases include at…

Despite the importance of asymmetric catalysis in both the pharmaceutical and commodity chemicals industries, asymmetric catalysis is under-represented in undergraduate chemistry laboratory curricula. A novel guided-inquiry experiment based on the asymmetric aldol addition was developed. Students conduct lab work to compare the effectiveness of…

The backpack weight a hiker is capable of carrying depends on several factors. These include the hiker's weight, body mass index (BMI), fitness, and training. It can also depend on the terrain on which the hiker travels, e.g., off-trail or on-trail. However, online advice has tended to focus on the hiker's weight and suggests that pack weight…
