Inspired by a theoretical view of knowledge as a resource, this study explored in detail how a student used knowledge as a resource when she engaged in problem-solving about rocks and what she learned as a result of the practice of solving scientific problems. The context of the study was an inquiry project conducted in an earth science course for…

The conception of racial categories from a biological perspective is unconsciously embedded in the individual's cognition. This is true even among university students majoring in biology and medicine. Even though students have never learned about "race" explicitly in formal biology class, they are highly likely to implicitly construct,…

In this study, we conducted an open laboratory activity that provided students with an opportunity to think…

Understanding the nature of science (NOS) has emerged as a core curricular goal since at least the 1960s. While science education reforms around the world have shed light on various epistemic and social underpinnings of science, how science curriculum documents portray the nature of other related disciplines such as mathematics and engineering has…

The purpose of this study was to investigate the features of modeling-based abductive reasoning as a disciplinary practice of inquiry in the domain of earth science. The study was based on an undergraduate course of a university of education, Korea, offered for preservice elementary teachers majoring in science as their specialty. The course…

The purpose of this study was to investigate the relationship of students' understanding of science knowledge, attitude and decision making on socio-scientific issues (SSI), especially on the issues of nuclear energy in Korea. SSI-focused instructions were developed to encourage students to understand and reflect on knowledge, attitude and…

This study examined and compared students' understanding of nature of science (NOS) with 521 Grade 8 Canadian and Korean students using a mixed methods approach. The concepts of NOS were measured using a survey that had both quantitative and qualitative elements. Descriptive statistics and one-way multivariate analysis of variances examined the…
