It is often necessary to enrich the teaching environment in order for students to learn optics in depth and to interpret the real optical situations with the information they have learned. In this study, a virtual teaching environment was developed using by Algodoo, a 2D simulation software. An eye model was created in order to explain the…

This work presents a sequence to introduce resistive gas sensors in the classroom. It explains the physical principle of the metal oxide semiconductor sensors and exemplifies its real interfacing through the sensor model MQ-2. Besides, it also presents the design of two electronic systems to indicate the level of alcohol concentration in the air,…

In some school, teacher-centered is commonly found in the learning process. The learning process itself is still in the form of direct transfer of knowledge from teacher to students. Actually, students will learn better if they are engaged in a meaningful learning activity. STEM project-based learning is one of the alternative teaching strategies…

Swedish preschool teachers must systematically document activities in the preschool in order to evaluate the quality of these activities. Pedagogical documentation is one form of documentation that is proposed. The aim of this article is to discuss and create knowledge of structures and tools based on different communicative aspects of pedagogical…

This article outlines a research study focused on the connections between natural science and art. In the instructional unit designed for the research study, multiple art forms were utilized, in order to reach multiple types of learners. Interdisciplinary, or integrated art instruction is a way to enhance understanding of and the connections…

Prismatic refraction is a classic topic in science education. To investigate how undergraduate students think about prismatic dispersion, and to see how they change their thinking when observing dispersed images, five teaching experiments were done and analysed according to the Model of Educational Reconstruction. For projection through a prism,…

This article describes a research study on the connection of Cultural Historical Activity Theory (CHAT) with Science Education in the early grades. The research study took place in the University of Ioannina, Greece with the support of the @fise research group. Within this frame, a narrative about light, colors and shadows was written as part of…

Generating, collecting, and analyzing data is an essential practice in the science classroom (NRC 2012). Taking this data and using it to craft an explanation that demonstrates understanding of content is another essential practice. But both practices can be challenging, and students often require teacher support to succeed. Accordingly, the…

We provide evidence that a learning activity called Energy Theater engages learners with key conceptual issues in the learning of energy, including disambiguating matter flow and energy flow and theorizing mechanisms for energy transformation. A participationist theory of learning, in which learning is indicated by changes in speech and behavior,…

In this article, the authors present a new way of teaching the phases of the Moon. Through the introduction of a "self shadow" (an idea of a shadow that is not well-known), they illuminate students' understanding of the phases of the Moon and help them understand the distinction between the shadows that cause eclipses and the shadows that relate…

Teaching physical science in the elementary and middle grades can be challenging for busy teachers faced with growing science demands and limited classroom resources. Robert Prigo provides fun and engaging activities using safe, available materials that educators can easily incorporate into lesson plans. Extensive examples, sample inquiry…

Presents three teaching ideas entitled (1) Rearview Mirrors; (2) Chills and Fevers; and (3) Science Activities and the Learner. The second idea presents a poem to help students with the relationship between Centigrade and Fahrenheit. The third idea presents activities on evaporation. (PR)

Intended for regular classroom teachers in intermediate science classes serving the gifted and talented student, the curriculum handbook is designed to give a basic understanding of gifted education, to list appropriate goals and objectives for the gifted student, and to suggest materials and strategies for implementation within the regular…

Describes the design and fabrication of a classroom hologram and activities utilizing the hologram to teach the concepts of real and virtual images to high school and introductory college students. Contrasts this method with three other approaches to teach about images. (MDH)

This instructional manual contains 20 learning activity packets for use in a workshop on lasers and fiber optics. The lessons cover the following topics: what a laser; coherent light; setting up the laser; characteristics of the laser beam; scattering of light; laser beam divergence, intensity, color, ophthalmology, and reflections; directivity of…
