In Japan, research activities by junior and senior high school students show an upward trend. However, there are limited examples of research activities in the field of elementary particles and atoms. This is due to the difficulty associated with procuring research tools such as accelerators or particle detectors. Therefore, we hosted the 'Accel…

We explored the potential for addressing nature of science through a historic narrative about disagreement between researchers concerning a socio-scientific issue, incidence of juvenile thyroid cancer following the Fukushima Daiichi nuclear accident. The narrative was developed from authentic sources and tested in two cycles. Eight groups of three…

A high-school third-year or undergraduate first-semester general chemistry laboratory experiment introducing simple-cubic, face-centered cubic, body-centered cubic, and hexagonal closest packing unit cells is presented. Latex balls and acrylic resin plates are employed to make each atomic arrangement. The volume of the vacant space in each cell is…

This research revealed that metal ions with different charges could significantly affect the viscosity of aqueous sodium carboxylmethylcellulose (CMC) solution. On the basis of an Ostwald viscometer, an improvised apparatus using a dropping ball for examining the viscosity of liquids/solutions has been developed. The results indicate that the…

This study investigated the relationship between gifted students' academic self-concept (ASC) and academic achievement (AC) in earth science with internationally representative high-school students from the third International Earth Science Olympiad (IESO) held in Taiwan in 2009. The results of regression analysis indicated that IESO students' ASC…

Various tactile methods, such as Braille, have been employed to enhance the recognition ability of chemical structures by individuals with visual disabilities. However, it is unknown whether reading aloud the names of chemical compounds would be effective in this regard. There are no systems currently available using an audio component to assist…

This paper examines the "subjectification" function of political education in democracy, considering the present situation of political education in Japan. In particular, from the point of view of political science, it focuses on the relationship between democratic theories and political education and considers whether the possibility of…

Three-dimensional (3D) nuclear charts were created using toy blocks, which represent the atomic masses per nucleon number and the total half-lives for each nucleus in the entire region of the nuclear mass. The bulk properties of the nuclei can be easily understood by using these charts. Subsequently, these charts were used in outreach activities…

The study examined students' perceptions related to emotional and cognitive engagement of linguistic and diagrammatic representational practices in science learning. Altogether, 251 Japanese sixth-grade (11-12 years old) and 187 ninth-grade students (14-15 years old) participated. The students' recognitions were measured by a self-report…

Women are underrepresented in physics. Because of the structure of the Japanese educational system, more women must choose physics as a subject for university entrance exams to increase the number of women studying advanced physics at university. In this study, we investigated the factors influencing girls' choice of physics for university…

Purpose: This study introduces the idea of "Kyouzai Kenkyuu" and examines its potentiality as a conceptual tool to point to the curriculum design process with a case of social science education. By doing so, this study can contribute to expanding the target of reflection from the practices "inside" classrooms toward the…

This study aims to explore an educational learning environment that supports students to learn conceptual modelling with the unified modelling language (UML). In this study, we call the describing models "UML programming." In this paper, we show an educational UML programming environment for science, technology, engineering, art, and…

The scientific integrity, perceptions of scientific misconduct, and students' needs in the research ethics education of Korean and Japanese gifted students were analyzed to address three questions. First, how well do students practice research ethics in their research? Second, how do students perceive scientists' misconduct? Third, do students…

This book identifies three types of influential forces that pose challenges to innovations: socio-cultural dynamics, teacher individuality, and local circumstances. It uses languages, cultural traits, and intellectual heritages in the Asia-Pacific region as an example to show the resistance to Western-based pedagogies due to disparities between…

Computer science for high school faces many challenging issues. One of these is whether the students possess the appropriate cognitive ability for learning the fundamentals of computer science. Online tests were created based on known cognitive factors and fundamental algorithms and were implemented among the second grade students in the…
