Nuclear chemistry and radiochemistry is a branch of chemistry that has high experimental risks, has high research costs, and is subject to certain prejudices. However, it has an extremely important influence on the development of human life. It is particularly important to emphasize the general education of nuclear chemistry and radiochemistry…

Heat and temperature concepts are found at all levels in the science curricula and are well-known for creating conceptual difficulties for learners. Students have difficulty understanding concepts related to heat, temperature, and thermal radiation. Inquiry-based pedagogies that can foster the learning of these difficult concepts are needed.…

In an effort to create meaningful user experiences, instructional designers participate in continuous projection and reflection during design. Empathic design draws on instructional designers' sensitivity toward their learners as a reference for design. Empathic forecasting, or predictions about an emotional reaction to future events, is an…

We engaged 47 eighth-grade students in a newly developed learning environment that integrates mobile augmented reality (AR) technology to support students' learning of nuclear energy use and radiation pollution, a topic related to a socioscientific issue (SSI) that involves complex reasoning considering scientific evidence and multiple…

This article describes a lesson on the greenhouse effect in which students explore blackbody radiation and Wien's law. The lesson, which has been tested in a variety of high school physics classrooms, uses probeware and online simulations and combines two well-established instructional strategies: the 5E Learning Cycle (Bybee et al. 2006) and the…

In this article we propose an activity aimed at introductory students to help them understand the Stefan-Boltzmann and Wien's displacement laws. It only requires simple materials that are available at any school: an incandescent lamp, a variable dc energy supply, and a computer to run an interactive simulation of the blackbody spectrum.…

Instructional design focuses on solving problems in a multitude of contexts. As such, designers are investigators, gathering evidence to optimally design solutions to learning problems within the identified context. The challenge described in this case study was the need to create an educational activity to promote interaction and collaboration…

Several ways of exploring the subject of global warming within the context of a conventional physics syllabus are suggested. The physics underlying greenhouse phenomena, the process of modelling (especially computers), possible future climatic scenarios, and the differing nature of the uncertainties associated with the many fields of study that…

Decades of research have provided evidence that food irradiation is a safe technology that can decrease the incidence of foodborne diseases; however, adoption of this technology has been slow. The purpose of our study was to qualitatively explore the effectiveness of various components of a professional development training on family and consumer…
