The main distinction between the overlapping fields of molecular biophysics and biochemistry resides in their different approaches to the same problems. Molecular biophysics makes more use of physical techniques and focuses on quantitative data. This difference encounters two difficult pedagogical challenges when teaching molecular biophysics to…

College students often experience difficulties in solving physics problems. These difficulties largely result from a lack of conceptual understanding of the topic. The processes of conceptual learning reflect the nature of the causal reasoning process. Two major causal reasoning methods are the covariational and the mechanism-based approaches.…

Elementary teachers have been identified as the single most important influence on student's future attitudes and motivations toward science. Research indicates that K-8 science teachers emphasize memorization more than the exploration of questions or critical thought as a result of their college science experiences. The reasons students gradually…

Data sharing among multiple lab sections increases statistical power of data analyses and informs student-generated hypotheses. We describe how to collect, organize, and manage data to support replicate and rolling inquiry models, with three illustrative examples of activities from a population-level biology course for science majors. (Contains 1…

Activities using the same historical case study can be designed for courses of varying degrees of proficiency by altering the format to suit each academic level. The case of Isidro Mejia, a construction worker who had six nails accidentally shot into his head from a nail gun, is the basis for a series of case study exercises. (Contains 4 figures.)

In recent years academics have commonly bemoaned the lack of essay-writing ability exhibited by their students. Whether or not the halcyon era in which undergraduates routinely knew how to construct a persuasive essay ever truly existed, it is certainly the case that contemporary students can benefit from advice on preparation of a long-format…

A combination of factors including longer working hours, emphasis on professional development, and increased access to the Internet have fuelled the current high demand for distance learning options in tertiary biology. Distance learner students come from a heterogeneous pool of ages, backgrounds and abilities and they require choice in how they…

This study examined how 16 Black, Latina, and American Indian women science students reacted to their undergraduate science classes. I focused on the meanings they made of the common features of university science documented by Seymour and Hewitt (1997), including large, competitive, fast-paced classes, poor teaching, and an unsupportive culture.…

Many researchers have investigated the effects of students' prior knowledge upon learning chemistry, for example, the tenacity of alternative conceptions. Knowledge about learning also shapes students' learning of chemistry. This research describes the development of CHEMX, a survey instrument that measures an aspect of knowledge about learning…

Recent research studies have reported on how novices and experts differ in storing, organizing, and retrieving subject matter knowledge and on how they apply their knowledge to solve new problems. These findings have been integrated and implemented in a computer environment to help novices improve their problem-solving skills. An outline of this…

Since 1959, ACT has collected and reported data on students' academic readiness for college. Because becoming ready for college is a process that occurs throughout elementary and secondary education, measuring academic performance over time in the context of college readiness provides meaningful and compelling information about the college…

Learning science is complex and difficult for many students and their understanding of science concepts and processes may be inaccurate or lacking. In an effort to improve the science achievement of underprepared students enrolled in a general science course, an integrative instructional model, "Dimensions of Learning" was used. Since acquiring…

The purpose of this longitudinal investigation was to assess the nature, development, and changes in preservice secondary science teachers' (n=12) conceptions/knowledge structures of subject matter and pedagogy as they proceeded through a fifth-year Master of Arts in Teaching (MAT) program. Open ended written questionnaires were used in Phase I of…

This thesis focuses on the definitional and cross-cultural processes involved in the development of an environmental education (EE) database of essential learnings, and the potential of the product in improving the effectiveness of international EE. Identifying the universal aspects of EE is crucial because EE is an evolving field, and is…

The primary purpose of this descriptive survey study was to compare the research priorities of preservice and inservice elementary teachers. Secondary purposes included (1) determining the research priorities of preservice elementary teachers; (2) investigating the differences in research priorities according to gender; (3) investigating the…
