Discusses a few of the causes for less-than-optimum educational uses of the Internet. Highlights include problems with state-level plans; the fear of pornography and Web censorship; the location of computers in computer labs; unrealistic overvaluing of standardized tests; and the current poor quality of Web pages. (LRW)

Presents a pre-lab exercise, an experimental setup, and discussion of computer-generated graphs that can be used to study the motion and energy of a bouncing ball. (WRM)

Describes the construction of an inexpensive recirculating aquaculture system that can hold up to 46 pounds of fish, invertebrates, and mussels for classroom use. The system is versatile, requires little maintenance, and can be used for both teaching and research purposes. (WRM)

Presents a problem-based, discovery-oriented activity on sickle-cell anemia that has been used for five years with more than 3000 secondary-level students and 200 teachers. (WRM)

Presents pencil-and-paper and laboratory activities to be used as part of a high school-level biotechnology unit. (WRM)

Presents an annotated bibliography tracing 20 years of "Writing Center Journal" scholarship covering a variety of issues which include teacher training, critical thinking, writing apprehension, peer tutoring, Internet sources and individual instruction. Contains annotations of all the articles and reviews published in this journal's…

UCLA's laboratory school is experimenting with the teacher-leader role as a way to provide ongoing learning opportunities for teachers. Teacher leaders serve as in-house experts who provide information, modeling, and assistance to other teachers. Choosing appropriate leader roles and teachers with credible leadership skills helps. (MLH)

Discusses the Youth Activity and Recreational Development (YARD) Center project, one school's efforts to return their school grounds to a more natural state in order to support integrated learning in a natural area, provide an environmental education workstation and writing laboratory, and have an aesthetically pleasing area for students and…

Perceptions of students in a Year 10 classroom were compared with those of their teacher at each of six schools with regard to the aims, regularity, conduct and assessment of laboratory work. Students in five of the schools had statistically different views from their teacher about the relative importance of 10 aims of laboratory work,…

Presents worksheet activities that enable students to explore the concept of electrostatic induction and learn the meaning of grounding. Students build two classic devices, the electrophorus and the leaf electroscope. (DDR)

Outlines the development of a kinetic study using the enzyme Lactaid to hydrolyze the synthetic substrate of lactose into an undergraduate laboratory experiment. Provides students with experience doing order-of-magnitude estimates. (DDR)

Discussion of technology assessment in schools focuses on how three school districts developed and carried out their own technology assessment rather than contracting it out. Highlights include computers in classrooms versus labs; computer trainers and teachers' needs; effects on student achievement; evaluation based on goals; authentic…

Describes using a computer statistical software package called Minitab to model the sensitivity of several microbes to the disinfectant NaOCl (Clorox') using the Kirby-Bauer technique. Each group of students collects data from one microbe, conducts regression analyses, then chooses the best-fit model based on the highest r-values obtained.…

Introduces a mobile science outreach project that is a learning laboratory for middle school and high school students. Applies the techniques and concepts of genetics and molecular biology used in modern biotechnology laboratories to solve problems. Discusses the advantages of MobileLab. (YDS)

Introduces a cytology laboratory course consisting of experimental design, laboratory preparation, laboratory implementation, and scientific write-up. (Contains 11 references.) (YDS)
