In this study, a paper folding activity task, which involved reaching the Pythagorean Theorem with a series of steps was designed. The aim of the task is to reach the Pythagorean Theorem with folding activities by deductive reasoning and logical inference. The study aimed to examine the effectiveness of the task and to share the patty paper…

The concept of fractions given in learning is the concept of part of whole and part of unit. The development of student's concepts of fractions can be built through fraction schemes. A partitive fraction scheme is a scheme that estimates the size of the fraction in the form of non-units to the whole that is not partitioned. The concept of…

Background: Internationally, the teaching of division has noted that the use of sharing situations with sharing actions (one-by-one distribution) is the predominant division model at the beginning of schooling. In South Africa, research suggests a sharing situation with sharing actions is also preferred in the early grades. Aim: This paper aims to…

In schools, literacy is often positioned as a fixed set of reading and writing skills. This can limit what counts as an academically acceptable literacy practice despite the complex and nuanced ways people communicate in their personal and social contexts. With this tension around conceptions of literacy in mind, I wondered how teachers thought…

Evolution is a key feature of undergraduate biology education: the American Association for the Advancement of Science (AAAS) has identified evolution as one of the five core concepts of biology, and it is relevant to a wide array of biology-related careers. If biology instructors want students to use evolution to address scientific challenges…

The algorithm for fraction multiplication is relatively easy to memorize and implement with accuracy. The simplicity of the algorithm masks the conceptual complexity involved in making sense of what fraction multiplication means in quantitative situations. One important interpretation of fraction multiplication involves fraction composition,…

The ability to relate physical concepts and phenomena to multiple mathematical representations--and to move fluidly between these representations--is a critical outcome expected of physics instruction. In upper-division quantum mechanics, students must work with multiple symbolic notations, including some that they have not previously encountered.…

As psychology grows in popularity, most students select professions related to therapy, which constantly deem statistics courses as irrelevant and accentuate negative attitudes. This study explores perspectives of knowledge, also known as epistemological frames, that students enrolled in a psychology-based course in statistics generate and the…

Demonstration interviews with 27 high school students (18-19 years old) were conducted in Zagreb, Croatia, using several standard experiments on interference and diffraction of light. Students were asked for their predictions, observations, and explanations of the experiments. In this process, many student difficulties were identified, both…

A significant body of scholarship in Physics Education Research (PER) has documented that students have intuitive knowledge resources that they use to make sense of the physical world. Similarly, for physicists, symmetry is fundamental to making sense of the universe. In this dissertation, I explore students' intuitive resources related to…

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…
