USING PSEUDO-HOLOGRAM TO DEMONSTRATE HOW TO MAKE PSEUDO HOLOGRAM

Abstract

The General Science Program, Faculty of Education, Bansomdejchaopraya Rajabhat University provides education to undergraduate students to be science teachers or educators in future. Students enrolled in this program are familiar with teaching and learning with economical materials but strive towards understanding of science through hands-on activities. Here, we report the Pseudo-hologram, which enables basic physical phenomena to be studied through simple, flawless, and instructive hands-on activities. This work describes such activities on a pseudo-hologram projector constructed by implementing a smartphone and a plastic frustum, together with an improved technique to enhance color contrast of illusion and reduce the reflection of ambient room light. In addition, it also presents a procedure in a beginning level to create the pseudo-holograph teaching video using PowerPoint program as an interactive teaching tool, which is capable of adopting the student knowledge to various interesting subjects. We envisage that this work would promote the active teaching and learning of science in primary or secondary levels of education.
