A Concept Inventory (CI) is an assessment to measure student conceptual understanding of a particular topic. This article presents the results of a CI for basic data structures (BDSI) that has been previously shown to have strong evidence for validity. The goal of this work is to help researchers or instructors who administer the BDSI in their own…

This work presents an immersive molecular simulation tool (Manta) based on virtual reality technology, which enables students to explore "real" molecular structures and chemical reactions on-the-fly. Manta can work as a virtual classroom and even a playground for chemistry education, where students learn the progress of chemical…

Purpose: The purpose of this paper is to present an exploratory analysis of campus community member (i.e. students, faculty, staff) definitions of sustainability, their perceptions of select elements of sustainability culture and the relationship between the two. Design/methodology/approach: Researchers implemented a cross-sectional design where…

Teachers are encouraged to connect mathematic instruction to the real-world by posing tasks that are situated in rich, relevant contexts, but research has found that many teachers integrate contextual problems (CPs) as motivators rather than as supports for conceptual development. To provide insight into how teachers' conceptions about CPs shift…

Contribution: This article discusses the use of manufacturing simulation games to study collaborative problem-solving skills in engineering students. The simulation represents the mass production paradigm in which large quantities of identical products are produced. Empirical data is collected from the simulation to evaluate the skills engineering…

This paper describes the conceptions about complex numbers that a group of university students has, these were built from the application of an activity sequence centered on these numbers. This sequence is based on the APOS theory, some aspects of semiotic representation theory, and the use of digital technology. Particularly, both the general…

This research aims to analyse students' conceptual understanding of chemical equilibrium matter using Physics Education Technology (PhET) Interactive Simulations. Students' misconceptions can be caused by the difficulty in connecting the sub-microscopic, macroscopic, and symbolic levels of understanding in chemistry. The study was conducted at a…

One of the most important problems of today's science education is the misconceptions and lack of knowledge that arise due to the science concepts not being learned in depth and meaningfully. For this reason, in this study, misconceptions, lack of knowledge, and scientific knowledge levels of science teachers about liquid pressure, which is one of…

Contribution: Understanding pupils' conceptualization of robots and programming can help teachers to avoid a disconfirmation experience by selecting more appropriate educational tools, robot designers in improving the robot design, and researchers in further improvement of the field. Background: Human-robot interaction (HRI) is affected by the…

The present study aimed to develop, introduce, and conduct an activity for the integration of augmented reality to the jigsaw IV technique in a planned and systematic manner. The activity developed for secondary school students is related to the "Pure Substances" subject which it is included in the "Particulate structure of…

A mental model is a concept that exists in students' minds and is used to describe and explain a phenomenon. This study aims to describe the transition-attempting mental model of students in understanding the concept of integers. This study uses a qualitative approach and the type of research conducted is descriptive. The subjects of this study…

This article presents a networking of two theories, the Extended Theory of Mathematical Connections (ETC) and the Onto-semiotic Approach (OSA). In particular, concordances and complementarities are identified in the respective conceptions of mathematical connections, as a result of applying these theoretical frameworks to a student's response…

Assessment of class participation (ACP) has been widely adopted in higher education because, presumably, it motivates students and facilitates active learning. Despite its popularity, evidence regarding how teachers perceive and implement ACP has remained largely anecdotal. This study explored teachers' perceptions and practices of ACP based on a…

The study aims at examining middle school mathematics teachers' conceptions of openended questions. A questionnaire consisting of open-ended items was applied to 40 mathematics teachers. The teachers were asked to define the open-ended question in general and the mathematical open-ended question in particular and provide examples to exemplify…

Although there has been intense criticism of NAPLAN in educational policy debates in Australia, little scholarly efforts have been made to understand the underlying cognitive mechanisms that contribute to the public narrative about the national testing program. We aim to provide tentative evidence about the way public perceptions about NAPLAN may…
