Explicit-reflective nature of science (NOS) instruction has demonstrated a positive impact on student learning. Although explicit-reflective NOS instruction often consists of questions that draw students' attention to NOS ideas, there are few recommendations in the science education literature about how the form of these questions might inform NOS…

In science education, learners' conceptions of scientists and their work are often assessed by the Draw-A-Scientist Test (DAST). Due to validity concerns, methodical literature demands the development of alternative instruments to measure learners' conceptions validly and efficiently. This study presents an instrument with 29 rating scale items to…

The purpose of this study is to explore how an online-structured dialogue environment supported (OSDE) collaborative learning about the nature of science among a group of trainee science teachers in the UK. The software used (InterLoc) is a linear text-based tool, designed to support structured argumentation with openers and "dialogue…

The starting point of the present research is the following question: since we live in an age that makes increasing use of visual representations of all sorts, is not the visual representation a learner constructs a window into his/her understanding of what is or is not being learned? Following this direction of inquiry, the present preliminary…

Examines both theoretical and practical perspectives on conceptual exchange--exchanging a student's entrenched view on a scientific topic for one based on actual scientific perspective. Endorses the conceptual-mediation model based on interference theory for changing an established view. (AIM)
