Spatial ability predicts success in STEM (Science, Technology, Education, and Mathematics) fields, particularly chemistry. This paper reports two studies investigating the unique contribution of mental rotation ability to spatial thinking in a STEM discipline. Using authentic disciplinary tasks from chemistry, we show that the difficulty of a…

This article notes the convergence of recent thinking in neuroscience and grounded cognition regarding the way we understand mental representation and recollection: ideas are dynamic and multi-modal, actively created at the point of recall. Also, neurophysiologically, re-entrant signalling among cortical circuits allows non-conscious processing to…

There is no agreement about the robustness of intuitive representations of the circulatory system and their susceptibility to change by instruction. In this paper, we analyse to what extent students with varying degrees of biology instruction and different ages (High School Health Science and Social Science students and first and final year…

In this paper we focus on some of the findings of the science education research community in the area of representations and problem solving. Problem solving depends on the construction and manipulation of mental models (internal representations) in the mind. A large knowledge base (declarative, procedural, strategic, situational, and schematic…

Examines third year university physics students' use of models when explaining familiar phenomena involving interaction between metals and electromagnetic radiation. Concludes that few students use a single model consistently. (Contains 27 references.) (DDR)

Reviews science education research into representations constructed by students in their interactions with the world, its phenomena, and artefacts. Features discussions of mental models, conceptual models, and the activity of modeling. (Contains 30 references.) (Author/WRM)

This research study focused on the knowledge structure of the domain of physics by describing the knowledge of experts, intermediates, and novices. In order to investigate these representations, a reiterative categorization task was employed using novice, intermediate, and expert subjects (N=27). The categories were classified as theory-, model-,…

Presents a series of standard demonstrations as examples of activities that can be used to introduce multiple concepts and tie different sections of an introductory physics course together. Contributes to changes in classroom dynamics by stimulating student engagement and encouraging inclusivity. (Contains 23 references.) (DDR)

Identifies middle school and college students' prior ideas about electrostatic induction. Presented students with observational evidence that supported or refuted their own prior ideas in an interview format. Concludes that the Lakatosian rather than the Popperian view is more acceptable in understanding students' responses to conflicting…

Explores whether construction of integrated knowledge structures by students can be stimulated by concept mapping and better visualization of concepts and their interrelationships. Significant effects of concept mapping as an instructional method could not be detected. (Contains 18 references.) (DDR)

This book focuses on three particular context-specific accounts of scientific thinking. The first section of the book presents research focused on extending knowledge of the fundamental components of scientific thinking. In the second section, research is presented that is focused primarily on how to build a structure for scientific thinking in…

This study investigates gender differences with regard to three factors of scientific literacy. The study involved students (N=772) in Grades 9 and 10. A 100-item multiple choice test based on National Science Education Standards was used to assess scientific literacy while gender differences were explored using analysis of variance procedures.…

Speculates about reasons for the lack of use of concept mapping as an instructional strategy. Concludes that the two main barriers to its extensive adoption are the epistemological beliefs of classroom teachers and the underlying philosophy of the curriculum. (Contains 45 references.) (DDR)
