Examines student attitudes towards biochemical experiments and their effect on student learning. Finds that biochemical experiments in the medical curriculum are valuable, but efforts should be directed more towards the development of students' attitudes and approaches to the exercise. (Author/CCM)

Presents a strategic consultancy model for establishing a business communication center. Discusses its application in two stages at the University of South Carolina in proposing and establishing such a center. Discusses identifying principles; identifying stakeholders; defining goals; analyzing strengths, weaknesses, opportunities, and threats;…

Discussion of computer-supported collaborative learning, distributed artificial intelligence, and intelligent tutoring systems focuses on the concept of agents, and describes a virtual learning environment that has a multi-agent system. Describes a model of interactions in collaborative learning and discusses agents for Web-based virtual…

Investigates the relationship between science and technology in industrial research laboratories, comparing the lab as "ivory tower" with the customer-oriented science approach. Describes similar patterns in science and technology curricula. Concludes that mutual commitment and shared project work would benefit integration of science and…

Considers some consequences of altering intracellular calcium supply by magnesium concentration changes. Focuses on using this procedure as an exercise with allied health students as they witness therapeutic uses of magnesium and other calcium entry inhibitors. (DDR)

Describes a project in which students create wind machines to harness the wind's power and do mechanical work. Demonstrates kinetic and potential energy conversions and makes work and power calculations meaningful. Students conduct hands-on investigations with their machines. (DDR)

Describes a set of laboratory activities in which students construct a model for the relationship between potential difference (measured in volts) and current (measured in amperes) in a DC circuit with a single resistor. (SAH)

Introduces the chicken wing project in which students assess the microbial contamination of chicken wings for the safety of foods. Uses the colony counting technique and direct wash fluid examination for determining the microbial contamination, and investigates methods to reduce the level of microbial contamination. (Contains 14 references.) (YDS)

Points out the difficulties of teaching evolution and recommends using simulations to circumvent these problems. Uses artificial organisms called caminalcules for teaching which allows students to focus on principles without preconceived ideas. (Contains 16 references.) (YDS)

Discusses revisions in general chemistry laboratory to include group project work. Describes evaluation techniques and sample projects. (MKR)

Explores associations between students' (n=1,592) perceptions of their chemistry laboratory classroom environment and their attitudes towards chemistry. Findings indicate significant associations between the nature of the chemistry laboratory classroom environment and the students' attitudinal outcome. "Integration" and "rule…

Laboratory schools for preservice teacher education are challenged by operational and philosophical dilemmas such as equity and increasing public school placements. Professional Development Schools face similar challenges in becoming institutionalized. They need strong connections among schools, colleges, and communities; a balance of innovation…

Presents the results of a study analyzing students' gestures and scientific discourse by supporting three assertions about the relationship between laboratory experiences, gestures, and scientific discourse. Discusses the implications for laboratory experiments which students should attempt to explain while still in the lab rather than afterwards…

Discusses procedures for investigating animal motion and makes suggestions for conducting a field or laboratory experiment using video. Recommends using nature videos to perform motion analysis. (YDS)

Explores using corn seeds to demonstrate plant growth and development. This experiment allows students to formulate hypotheses, observe and record information, and practice mathematics. Presents background information, materials, procedures, and observations. (SAH)
