Purpose: This study aims to explore the effects of an alternative learning environment, such as the video game making (VGM) within science content, on computational thinking (CT) skills development and student performance. Design/methodology/approach: A didactic intervention was performed for five weeks. Two student groups were taught the same…

Fractals are geometric objects used to describe irregular shapes that have a fractional dimension and commonly appear in nature. Although several proposals for the study of perfect fractals at the basic level are present in the literature, only few proposals for the study of real fractals exist, which does not seem reasonable considering the…

Since most emotional regulation research is about teachers regulating their own emotions, this study sought to examine how teachers view emotions and respond to their students' emotions. Drawing from an interactional view of emotions and emotion regulation, five science teachers were interviewed for 60-75 minutes about the emotions experienced by…

Play-based approaches to science learning allow children to meaningfully draw on their everyday experiences and activities as they explore science concepts in context. Acknowledging the crucial role of the teacher in facilitating science learning through play, the purpose of this qualitative study was to examine how teacher-guided play, in…

Most didactic lab experiments deal with the influence of temperature, concentration, pressure, surface area, and catalysts on chemical kinetics; however, few of them explore the influence of light radiation and the presence of inhibitor agents on reaction rates. In order to investigate the effects of the radiation source and the presence of…

A multiweek laboratory experiment is described, which guides students to use data to make decisions through multiple steps, before reaching a final conclusion. The lab focuses on the comparisons of fluorescence and absorbance spectroscopies to determine the concentration of a desired substance in an unknown sample in consideration of a complex…

Over the past several decades, green chemistry has gained prominence in chemistry education. However, the development of green chemistry curricula has not reached all levels of education equally, focusing mainly on elective and upper division courses. We deliberately focused our green chemistry curriculum redesign on a high enrollment introductory…

Based on the results of an online survey of 500 Québec's elementary (K-6) teachers conducted in 2015 that probed the way respondents teach astronomy to their classrooms, their background in S&T, their pre-service education, their aims and goals for astronomy teaching, their attitude toward teaching astronomy, the resources and materials they…

A video is taken of a road-sign mirage from the passenger seat in a car traveling at constant speed on a highway. The video spans the duration of seeing the mirage of the sign, viewing the vanishing of the mirage as the car approaches, and passing the road sign. The mirage angle, defined as the angle with respect to the horizontal at the moment…

Purpose: The most important element in Problem Based Learning (PBL) that has a significant place in science education is the structure of the problem. Even though it seems easy to formulate the problem that is suitable for this approach at first glance, it is rather difficult to find the problem that will meet the purposes of education. When…

This article reports on the effect of using a diagram to develop primary students' conceptual understanding about electric circuits. Diagrammatic representations of electric circuits are used for teaching and assessment despite the absence of research on their pedagogical effectiveness with young learners. Individual interviews were used to…

Teaching the periodic table is a central part of chemistry. This might involve memorizing the symbols of the elements, learning about the properties of the families, or understanding its general organization. This year, The International Year of the Periodic Table, marks its 150th anniversary, and represents a good opportunity to highlight its…

The illustration characteristics of 221 visual representations (VRs) of submicroscopic particles in nine Greek secondary chemistry school textbooks from the last three decades were analyzed. This analysis was done to develop a taxonomy that could help science teachers and curricula designers evaluate the efficacy of such characteristics on student…

Friction is one of the common forces that affect our everyday life and one of the oldest problems studied in physics. An interpretation of its nature is included in all general physics courses, in both high school and college. The desire and need to better understand it guided a long list of scientists who devoted themselves to the study of…

Undergraduate quantum mechanics (QM) uses a variety of notations, each with their own advantages and constraints, for representing quantum states and carrying out individual calculations. An example of this can be seen when calculating expectation values, which can be solved using several different methods. Analysis of written exam data given at…
