In contrast to most other thermodynamic data, entropy values are not given in relation to a certain--more or less arbitrarily defined--zero level. They are listed in standard thermodynamic tables as absolute values of specific substances. Therefore these values describe a physical property of the listed substances. One of the main tasks of…

An important learning goal of a molecular biology curriculum is the attainment of a certain competence level in experimental design. Currently, undergraduate students are confronted with experimental approaches in textbooks, lectures and laboratory courses. However, most students do not reach a satisfactory level of competence in the designing of…

The spaces and structures used for undergraduate science often work against new teaching methods and fail to provide environments that attract the brightest students to science. The undergraduate science building often offers little to inspire the imaginations of young minds. The typical undergraduate science building also tends to work against…

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.)

Increasingly, national stakeholders express concern that U.S. college graduates cannot adequately solve problems and think critically. As a set of cognitive abilities, critical thinking skills provide students with tangible academic, personal, and professional benefits that may ultimately address these concerns. As an instructional method, writing…

This study investigated the kinds of dialogic behavior engaged in by students while studying a difficult physics course at the Open University, UK. Research objectives were twofold: (1) to document what dialogue types, mediated through which resources, were utilized by students to overcome conceptual difficulties that emerged while reading the…

Pharmacology is taught on a dedicated module for nurse prescribers who have a limited physical science background. To facilitate learning a problem-based approach was adopted. However, to enhance students' knowledge of drug action a PharmaCALogy software package from the British Pharmacological Society was used. Students were alternately given a…

This study used quantitative and qualitative methods to examine the use of inclusive pedagogy by science, technology, engineering, and mathematics (STEM) faculty at three community colleges. The purpose was to identify barriers to the adoption of inclusive teaching methods for diverse learners and students with disabilities and to propose ways to…

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…
