Background: This study investigates the role of figures of speech in the process of conceptual change in the physics classroom. Purpose: Its objectives are to examine what teachers and students perceive to be the advantages in using figures of speech in teaching physics concepts, what they perceive to be the challenges in using them, and how…

Climate change encompasses a broad and complex set of concepts that is often challenging for students and educators. Using a learning progressions (LPs) knowledge system, we developed a LP that described student learning of climate change. In this exploratory study, we present findings from written assessments of climate change (n = 294) and…

Excessive exposure to solar ultraviolet (UV) radiation causes sunburn and has been consistently associated with increased susceptibility to melanoma and skin ageing. Acknowledging the need to promote healthy sun exposure habits, numerous educational initiatives have been developed to raise public awareness towards this issue. However, studies…

Background: The motivation for this work is built upon the premise that there is a need for research-based materials for design-based science instruction. In this paper, a small portion of our work investigating the impact of a LEGO[TM] engineering unit on fourth grade students' preconceptions and understanding of animals is presented. Purpose:…

Through a non-experimental descriptive and comparative mixed-methods approach, this study investigated the experiences of sixth grade earth science students with groundwater physical models through an extended SE learning cycle format. The data collection was based on a series of quantitative and qualitative research tools intended to investigate…

This study of advanced readers in Reading First (RF) classrooms was part of a larger evaluation of one state's RF implementation. The study's purposes were to (a) assess the longitudinal growth of advanced primary readers as compared with their non-advanced-reading peers over a 3-year timeframe and (b) determine the degree to which RF classrooms…

This study is an investigation into the science literacy of college genetics students who were given a modified curriculum to address specific teaching and learning problems from a previous class. This study arose out of an interest by the professor and researcher to determine how well students in the class Human Genetics in the 21st Century…
