Theoretical and practical foundations of basic electrochemical concepts of heterogeneous charge transfer reactions that underline electrochemical processes are presented for their detailed study by undergraduate and postgraduate students. Several simple methods for calculating key variables, such as the half-wave potential, limiting current, and…

For a teacher who teaches science concepts to a group of students, he should investigate the level of understanding of various background variants, including differences in dominant multiple intelligence owned by students. This level of understanding can be identified from students' ability to understand concepts in a series of learning phases…

The conceptual development of natural number in preschoolers is well-researched. However, less is known about the conceptual development of zero. Recent studies suggest that children develop an understanding of zero after learning to count. It remains unclear, when a conceptual understanding of "zero" as number word for an empty set…

The dominant narratives currently offering critique of the neoliberal university suggest a professional environment that is both uncaring and unhealthy. This paper adopts a Deleuzian gaze on the rhizomatic multiplicity of teaching to identify and reinterpret key lines of flight within this assemblage -- identified as care, pedagogic health and…

In this article, we describe a case study that was conducted within a study aiming to diagnose grade 5 students' concept images of parallelograms. The theoretical framework that we adopted for this study was that of concept definition--concept image as reported by Tall and Vinner ("Educational Studies in Mathematics" 12:151-169, 1981), a…

This study analysed students' auto-photographs with transcripts to understand their conceptions of learning and to compare the differences among different grade levels. A total of 549 Taiwanese college students took photographs and wrote accompanying textual descriptions to illustrate how they conceptualised learning. A coding checklist was…

In this article, I discuss the potential of developing a kind of worldview education that has the purpose of enabling teachers and students to understand how worldviews are formed. I explore how suggestions of Ann Taves can be helpful towards such an aim and pay special attention to research into self-defined 'non-religious people. It seems their…

The study of the motion of a projectile, thrown at an angle to the horizon, is a wonderful classical problem. This issue has been the subject of great interest to investigators for centuries. Currently, the study of parabolic motion, in the absence of any drag force, is a common example in introductory physics courses. The theory of parabolic…

This study aims to examine the concept images of pre-service mathematics teachers for the concepts of single-variable and multivariable functions. In the present research, which was conducted with the case study method, a test consisting of three open-ended questions was used to obtain data about the definition of the concept of function and the…

Teaching science concepts for conceptual understanding has its challenges. Bringing about conceptual change in the science classroom can be difficult because most concepts are complicated and often counter-intuitive in the teaching and learning of science concepts. A review of the literature indicates that the conceptual change model, CCM can be…

In this article we report on middle school students' understanding of concepts related to the second step of the statistical problem-solving process, study design: create a plan and collect data. Students participated in an open-ended statistics lesson involving nonexperimental study design. For this research we analyzed the students' discourse…

Scientific literacy is the primary goal of elementary science education. Scientific literacy requires an overall understanding of what science is, and how and why scientific knowledge is developed. The normal assumption is that as students progress in school, they learn more. One would expect students to become more scientifically literate as they…

Research suggests that tasks that use technology as a reorganizer (technology is used to produce dynamic representations) are linked with the development of students' conceptual knowledge, yet many secondary mathematics textbooks in the USA predominantly include tasks that use technology as an amplifier (technology is used to produce static…

This theoretical paper sets forth two "aspects of predication," which describe how students perceive the relationship between a property and an object. We argue these are consequential for how students make sense of discrete mathematics proofs related to the properties and how they construct a logical structure. These aspects of…

We present a detailed yet easy-to-follow discussion of the mathematical treatment of time-resolved spectroscopic data in a model-based approach. This is accompanied and complemented by an example of a colorful and pedagogically rich chemical reaction: the permanganate oxidation of sugars in basic aqueous media (often known as the chameleon…
