We have developed new rotors that can be classified into three groups by changing the rotors used in simple motors into various types. Group I has a semicircular shape rather than a perfect circle or square shape, group II has a structure consisting of several closed circles on one plane, and group III has a three-dimensional shape. We wanted to sh...

Although the concept of light is important in the elementary school curriculum, substantial research suggests that students and teachers have difficulties in understanding it. Therefore, it is necessary to analyze the reasons for these difficulties-whether it is due to the content or due to the presentation method of contents, structure, and expres...

Talent development in science is a national investment as it is key to enhancing national competitiveness. However, even after undergoing a 3-year training in a science gifted academy, 8.5% of South Korea’s gifted students choose to enter medical school rather than pursuing a science or technology major. By conducting in-depth interviews with five...

In the results to these tests and questionnaires, teachers demonstrated...

The purpose of this study is to explore a possibility finding gifted underachievers who have high spatial ability, but low verbal ability in elementary science field. In Korea, because teachers used to refer students` academic achievement only when they recommend gifted students, underachievers used to be excluded. The participants are 5th-grade st...

To understand the synergy of collaboration and to apply this understanding to education, an analysis of how a team solves a problem and the sharing of their mental models is needed. This paper analyzed two things qualitatively to find out the source of synergy in a collaborative problem-solving process. First, the sharing contents in team mental mo...

Even after learning electric current, elementary school students have various non-scientific conceptions and difficulties. Because flow of charge is not visible. Also elementary school students do not learn theory but phenomena, so they cannot transfer theoretical perspective to new situation. In this research, we have designed instruction based on...

We investigated gifted students` scientific integrity, perception of scientific misconduct and needs for research ethics education. For this study, 267 science academy students who have participated in R&E program responded to questionnaire of those three parts. The major findings are as follows: First, 45.31% of gifted students answered that they...

In physics, metal simulation is an important mechanism to understand and create concepts. If students have difficulty in mental simulation, understanding the concept of physics also gets difficult. By providing guide for spatial manipulation to students, 3D simulation contents can help them understand the concept of physics. In this study, the 3D s...

Ray drawing in geometrical optics is an effective method for visible imagery of light.
