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…

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…

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…

A simple experiment is presented to visualize inferior and superior mirages in the laboratory. A quantitative analysis is done using ray tracing with both photographic and computational techniques. The mirage's image, as seen by the eye or the camera lens, can be used to analyse the deflection and inversion of light rays. (Contains 6 footnotes, 1…

This document contains a U.S. Navy Rate Training Manual and Nonresident Career Course which form a self-study package to teach the theoretical knowledge and mental skills needed by the Opticalman Third Class and Opticalman Second Class. (Opticalmen maintain, repair, and overhaul telescopic alidades, azimuth and bearing circles, binoculars,…

Discusses the energy flux-density of two beams of light of equal energy that are intersected at a given angle. Examines an apparent contradiction to the physics law of conservation of energy known as Vavilov's paradox. (MDH)

Describes science demonstrations with light-emitting diodes that include electrical concepts of resistance, direct and alternating current, sine wave versus square wave, series and parallel circuits, and Faraday's Law; optics concepts of real and virtual images, photoresistance, and optical communication; and modern physics concepts of spectral…

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…

Discusses how teachers in early childhood education and care settings can use children's picture books to teach physical science concepts. Presents activities for toddlers and preschoolers related to the areas of light and optics, sound and music, and machines and power. Includes for each activity a list of materials and instructions for teachers.…

These lesson plans and student study guides and workbooks for a secondary-postsecondary-level course in continuous photoprocessing are one of a number of military-developed curriculum packages selected for adaptation to vocational instruction and curriculum development in a civilian setting. Purpose stated for the course is to expose students to…

This concept module on radiation is one of thirteen modules that provide a flexible, laboratory-based physics instructional package designed to meet the specialized needs of students in two-year, postsecondary technical schools. Each of the thirteen concept modules discusses a single physics concept and how it is applied to each energy system.…
