Tenenbaum, Harriet R.; To, Cheryl; Wormald, Daniel; Pegram, Emma – Science Education, 2015
Darwinian evolution is difficult to understand because of conceptual barriers stemming from intuitive ideas. This study examined understanding of evolution in 52 students (M = 14.48 years, SD = 0.89) before and after a guided field trip to a natural history museum and in a comparison group of 18 students (M = 14.17 years, SD = 0.79) who did not…

Morin, Olivier; Simonneaux, Laurence; Simmoneaux, Jean; Tytler, Russell; Barraza, Laura – Science Education, 2014
Within the increasing body of research that examines students' reasoning on socioscientific issues, we consider in particular student reasoning concerning acute, open-ended questions that bring out the complexities and uncertainties embedded in ill-structured problems. In this paper, we propose a socioscientific sustainability reasoning…

Russ, Rosemary S.; Lee, Victor R.; Sherin, Bruce L. – Science Education, 2012
Researchers in the science education community make extensive use of cognitive clinical interviews as windows into student knowledge and thinking. Despite our familiarity with the interviews, there has been very limited research addressing the ways that students understand these interactions. In this work, we examine students' behaviors and speech…

Bivall, Petter; Ainsworth, Shaaron; Tibell, Lena A. E. – Science Education, 2011
This study explored whether adding a haptic interface (that provides users with somatosensory information about virtual objects by force and tactile feedback) to a three-dimensional (3D) chemical model enhanced students' understanding of complex molecular interactions. Two modes of the model were compared in a between-groups pre- and posttest…

Maeyer, Jenine; Talanquer, Vicente – Science Education, 2010
The characterization of students' cognitive biases is of central importance in the development of curriculum and teaching strategies that better support student learning in science. In particular, the identification of shortcut reasoning procedures (heuristics) used by students to reduce cognitive load can help us devise strategies to foster the…

Fortus, David – Science Education, 2009
Making assumptions is an important step in solving many real-world problems. This study investigated whether participants who could solve well-defined physics problems could also solve a real-world physics problem that involved the need to make assumptions. The participants, who all had at least a BA in physics, were videotaped "thinking aloud"…

Russ, Rosemary S.; Coffey, Janet E.; Hammer, David; Hutchison, Paul – Science Education, 2009
When teachers or students assess the quality of ideas in science classes, they do so mostly based on "textbook correctness"; ideas are good to the extent they align with or lead to the content as presented in the textbook or curriculum. Such appeals to authority are at odds with the values and practices within the disciplines of science. There has…

Jones, M. Gail; Minogue, James; Tretter, Thomas R.; Negishi, Atsuko; Taylor, Russell – Science Education, 2006
This study investigated the impact of haptic augmentation of a science inquiry program on students' learning about viruses and nanoscale science. The study assessed how the addition of different types of haptic feedback (active touch and kinesthetic feedback) combined with computer visualizations influenced middle and high school students'…

Taber, Keith S. – Science Education, 2003
This paper describes the conceptualizations, or mental models, of the nature of the bonding and structure of metals of a group of U.K. college students. It is suggested that these mental models may be understood in terms of the students' prior learning about covalent and ionic bonding, and the prevalence of a common alternative conceptual…

Stuck, Gary B.; Wyne, Marvin D. – Science Education, 1970
Experiment compares the effect of equilibration type training to the effects of S-R reinforcement type training in developing weight-conservation concepts in second and third grade pupils. S-R group performed significantly better than control group on initial posttest for conservation of weight. A measure for permanence of the conservation beliefs…

Preece, Peter F. W. – Science Education, 1978
Discusses the nature of the internal representation of cognitive structure, the methodological problems involved in mapping it, and the proposed kinds of "maps." Reviews research on the organization of scientific concepts in semantic memory. (GA)

Palmer, David H. – Science Education, 1999
Describes a study that investigated whether scientific and nonscientific understandings in the same content area are linked. Finds that students' (n=107) explanations indicate that they were using an "if-then" type of reasoning which linked scientific and nonscientific conceptions. Contains 39 references. (Author/WRM)

Halloun, Ibrahim – Science Education, 1998
Presents the epistemology of scientific concepts from a schematic modeling perspective. Discusses students' initial cognitive states based on the level of commensurability between students' own concepts and their scientific counterparts. Contains 87 references. (DDR)

Tsaparlis, Georgios; Angelopoulous, Vasileios – Science Education, 2000
Presents a test of the limits of the Johnstone--El-Banna model of problem solving as related to students' responses to organic-synthesis problems. Finds that the predicted pattern was observed in both samples, although the model was more useful for students without previous problem-solving training and for field-independent and field-intermediate…

Cauzinille-Marmeche, Evelyne; And Others – Science Education, 1985
Investigated the role of "a priori" ideas in planning experiments and data processing leading to inferences. Thirty-one students (ages 11-13) observed a "combustion/candle in a closed container" experiment and were asked to interpret sets of measurements. Findings, among others, show that children preferentially experiment on…
