Analysis of Learning Effects of Improved Digital Microscope System with Tabletop Interface in Elementary Science Education

Abstract

This comparative study examined the differences between utilizing optical microscopes and a digital microscope system with a tabletop interface in an elementary school science class. First, an objective assessment was conducted for understanding microorganisms in water using an in-class test. Second, survey responses about microscopic observation tasks were analyzed. Finally, we performed a protocol analysis by analyzing students’ responses while they observed the digital microscope system with tabletop interface. The results from the first assessment showed that there was a significant difference between students’ comprehension using a digital microscope system with tabletop interface and using the optical microscope. The results from the second assessment showed that the digital system was more effective than the optical microscopes for microscopic observation tasks such as finding, focusing, observing, and discussing. The results from the final assessment suggested that by projecting the microscopic image through the digital equipment, it was possible to encourage the students to consider the microscopic images and engage in cooperative dialogue, which is useful for improving their understanding.
