Extant literature has preliminarily confirmed the potential benefits of holographic projections for educational purposes. Yet, students' experiences of learning by holographic projection have rarely been addressed. The main purpose of this study was therefore to explore students' conceptions of and approaches to learning by holographic projection.…

This paper describes a method to demonstrate that the plane of the lunar orbit around Earth and the plane of the ecliptic (the plane of Earth's orbit around the Sun) are inclined with respect to each other, and to present a method for measuring the angle of the inclination. The angle between the diameter of the Moon's orbit when the Moon passes…

Teaching and learning situations nowadays typically build on richly illustrated material or multimodal presentations. Under these circumstances, the transparency of images and models used for explaining various phenomena becomes central. The present study deals with 20 Swedish children, 9-12 years old, discussing an illustration meant to show the…

We present the development and validation of a new assessment tool, the Moon Phases Concept Inventory for Middle School (MPCI-MS), a concept inventory about the phases of the moon targeting students aged 10 to 14 years old. Items in the questionnaire are based on a careful examination of the concept domain of phases of the moon, ideas and concepts…

This article describes a unit in which students investigate total solar eclipses, such as the one coming August 21, from several perspectives. It incorporates mathematical thinking and aligns with the "Next Generation Science Standard." This article refers to physical, virtual, and mathematical modeling. Various models and perspectives…
