It is widely acknowledged that there are problems with school science in many developed countries of the world. Such problems manifest themselves in a progressive decline in pupil enthusiasm for school science across the secondary age range and by the fact that fewer students are choosing to study the physical sciences at higher levels and as…

Fear extinction is defined as a decline in conditioned fear responses (CRs) following nonreinforced exposure to a feared conditioned stimulus (CS). Behavioral evidence indicates that extinction is a form of inhibitory learning: Extinguished fear responses reappear with the passage of time (spontaneous recovery), a shift of context (renewal), and…

Providing adequate computing lab support for Management Information Systems (MIS) and Computer Science (CS) programs is a perennial challenge for most academic institutions in the US and abroad. Factors, such as lack of physical space, budgetary constraints, conflicting needs of different courses, and rapid obsolescence of computing technology,…

The laboratory component of a first-semester general chemistry course for science majors is described. The laboratory involves a semester-long project undertaken in a small-group format. Students are asked to examine whether plants grown in soil contaminated with lead take up more lead than those grown in uncontaminated soil. They are also asked…

We have developed a wet lab DNA microarray simulation as part of a complete DNA microarray module for high school students. The wet lab simulation has been field tested with high school students in Illinois and Maryland as well as in workshops with high school teachers from across the nation. Instead of using DNA, our simulation is based on pH…

"One-to-one" technology enhanced learning research refers to the design and investigation of learning environments and learning activities where every learner is equipped with at least one portable computing device enabled by wireless capability. G1:1 is an international research community coordinated by a network of laboratories conducting…

The process of a successful undergraduate student-faculty research collaboration involving a student with documented learning disabilities is detailed. As the student developed research skills, she also learned how to develop her own learning strategies. At the same time, the faculty member learned strategies adaptable to all student-faculty…

A positive correlation is well established between obesity and the susceptibility to develop metabolic syndrome, a multifactorial disease dramatically associated with an enhanced mortality risk in the developed world. A high prevalence of obesity has recently been described at La Reunion Island, a French department in the Indian Ocean.…

This writing-intensive, lab-based, nonmajor biology course explores scientific inquiry and biological concepts through specific topics illustrated or inaccurately depicted in works of science fiction. The laboratory emphasizes the scientific method and introduces several techniques used in biological research related to the works we study.…

We report on a study of a laboratory teaching apprenticeship program designed to improve graduate teaching assistant (GTA) performance. To catalyze GTAs as laboratory teachers we constructed learning goals, synthesized previous literature into a design model and a developmental path, and built two instruments to measure 12 strategic pedagogical…

Humanity delights in spinning conceptual models of the world. These models, in turn, mirror their respective root metaphors. Three root metaphors--spiritual, organic, and mechanical--have dominated western thought. The spiritual metaphor runs from Plato, through Hegel, and connects with Montessori. The organic metaphor extends from Aristotle,…

The aim of this study was to investigate the effectiveness of a problem-based learning (PBL) approach in a physical chemistry laboratory course. The parameters investigated were students' attitudes towards a chemistry laboratory course, scientific process skills of students and their academic achievement. The design of the study was one group…

This paper presents the development of a 3-D virtual environment in Second Life for the delivery of standards-based science content for middle school students in the rural Appalachian region of Southeast Ohio. A mixed method approach in which quantitative results of improved student learning and qualitative observations of implementation within…

The "Student Evaluation of Instruction" (SEOI) was administered to all full-time and part-time faculty. Approximately 91,530 surveys were sent out in 4,980 envelopes; 58,604 surveys were returned to the Office of Institutional Research. The return rate for the paper surveys was 64% including late submissions. Instructors' reports were…

The "Student Evaluation of Instruction" (SEOI) was administered to all full-time and part-time faculty. Approximately 82,806 surveys were sent out in 4,830 envelopes; 52,464 surveys were returned to the Office of Institutional Research. The return rate for the paper surveys was 63% including late submissions. Instructors' reports were…
