Underwood, Sonia M.; Reyes-Gastelum, David; Cooper, Melanie M. – Science Education, 2015
Longitudinal studies can provide significant insights into how students develop competence in a topic or subject area over time. However, there are many barriers, such as retention of students in the study and the complexity of data analysis, that make these studies rare. Here, we present how a statistical framework, discrete-time survival…

Amin, Tamer G.; Jeppsson, Fredrik; Haglund, Jesper; Stromdahl, Helge – Science Education, 2012
Various features of scientific discourse have been characterized in the science education literature, and challenges students face in appropriating these features have been explored. Using the framework of conceptual metaphor, this paper sought to identify explicit and implicit metaphors in pedagogical texts dealing with the concept of entropy and…

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…

Brandt, Carol B. – Science Education, 2008
This case study explores how an American Indian woman experienced scientific discourse and the issues of language, power, and authority that occurred while she was an undergraduate student at a university in the southwestern United States. This ethnographic research, using a phenomenological perspective, describes her experiences as she searched…

Windschitl, Mark; Thompson, Jessica; Braaten, Melissa – Science Education, 2008
One hundred years after its conception, the scientific method continues to reinforce a kind of cultural lore about what it means to participate in inquiry. As commonly implemented in venues ranging from middle school classrooms to undergraduate laboratories, it emphasizes the testing of predictions rather than ideas, focuses learners on material…

Talanquer, Vicente – Science Education, 2008
We investigated general chemistry students' intuitive ideas about the expected properties of the products of a chemical reaction. In particular, we analyzed college chemistry students' predictions about the color, smell, and taste of the products of chemical reactions represented at the molecular level. The study was designed to explore the extent…

Briscoe, Carol; Prayaga, Chandra S. – Science Education, 2004
This interpretive case study describes a collaborative project involving a physics professor and a science educator. We report what was learned about factors that influenced the professor's development of teaching strategies, alternative to lecture, that were intended to promote prospective teachers' meaningful learning and their use of canonical…

Coll, Richard K.; Treagust, David F. – Science Education, 2003
Mental models of metallic bonding held by learners from three academic levels, secondary school (year 12), undergraduate, and postgraduate, were probed using semistructured interviews including the use of Interviews-About-Events focus cards depicting metallic properties and cards containing depictions of models from curriculum material. The…

Trumbull, Deborah J.; Kerr, Patricia – Science Education, 1993
Discusses results obtained through interviews with university science teachers with regard to their philosophies and practices in college science classrooms. Data revealed that teachers are not satisfied with all aspects of their teaching; however, they are not sure how to make changes that would maximize student learning. (ZWH)

Brumby, Margaret N. – Science Education, 1984
Examined Australian medical school students' (N=150) conceptual frameworks and reasoning patterns related to natural selection. Results indicate that the majority believed that evolutionary changes occur as a result of need. Implications related to student learning and to science and medical education are considered. (JN)

Stewart, Jim; And Others – Science Education, 1989
Describes an intelligent tutoring system named MENDEL, including problem GENERATOR, TUTOR, student MODELER, ADVISOR, hypothesis CHECKER, and problem SOLVER. This software may be used by high school or university biology students as a tool for learning concepts and problem-solving strategies in transmission genetics. (YP)

Albert, Edna; Van Der Mark, M. H. – Science Education, 1981
Investigates and substantiates the effectiveness of the peer teaching approach on the ability of preservice elementary teachers (N=60) to acquire concepts selected from the Elementary Science Methodology Course and on their attitudes towards science and elementary school science. (CS)

Novick, Shimshon; Nussbaum, Joseph – Science Education, 1981
Traces the development of a pencil and paper instrument which measures the change in pupils' (N=576) conception of the particle model of matter. Responses of four groups of children in grades 5-12 and university sophomore nonscience majors revealed that some cognitive difficulties are experienced at all ages. (CS)
