The rise of social media platforms and the subsequent lack of traditional gatekeeping mechanisms contribute to the multiplied spread of scientific misinformation. Particularly in these new media spaces, there is a rising need for science education in fostering a science media literacy that enables students to evaluate the credibility of scientific…

This study investigated the effects of a modeling-based text on 10th graders' modeling competencies. Fifteen 10th graders read a researcher-developed modeling-based science text on the ideal gas law that included explicit descriptions and representations of modeling processes (i.e., model selection, model construction, model validation, model…

In secondary science education, the learning and teaching of coherent conceptual understanding are often problematic. Context-based education has been proposed as a partial solution to this problem. This study aims to gain insight into the development of conceptual coherence and how context-embedded learning-teaching activities (LT) can promote…

This exploratory study examines how a series of laboratory activities designed using a new instructional model, called Argument-Driven Inquiry (ADI), influences the ways students participate in scientific argumentation and the quality of the scientific arguments they craft as part of this process. The two outcomes of interest were assessed with a…

One goal of project-based science is to promote the development of scientific discourse communities in classrooms. Holding rich high school scientific discussions is challenging, especially when the demands of content and norms of high school science pose challenges to their enactment. There is little research on how high school teachers enact…

The process of construction of meanings for the concepts of concentration and neutralization is explored in terms of "contextualizing practices" (Lemke, 1990, "Talking Science. Language, Learning and Values," Norwood, NJ: Ablex) creation of meanings through connections established among actions and their context. This notion is expanded to include…

The study examines how social and cultural factors mediate the teaching and learning of science in an Australian high school. Grade 10 students, many of them new migrants, often transient and from circumstances of economic hardship, were taught a 5-week unit on chemistry by a teacher with social and cultural histories similar to those of most of…

In this study, students' views on the nature of science (NOS) were investigated with the use of a large-scale survey. An empirically derived multiple-choice format questionnaire was administered to 1702 Korean 6th, 8th, and 10th graders. The questionnaire consisted of five items that respectively examined students' views on five constructs…

Teaching nonscience majors topics in biotechnology through case studies is the focus of this research. Our "Biotechnology, Environment, and Related Issues" module, developed within the "Science for All" framework, is aimed at elevating the level of students' scientific and technological literacy and their higher order thinking…
