Provides a brief overview of primary computer network structures serving the academic research community and discusses plans for the transformation of Internet into a National Research and Education Network (NREN). The scope of resources likely to be available to users through the NREN are described, the concept of national collaboratives is…

Discusses the use of an optional computer graphics laboratory that has been successful with at-risk elementary school students. The role of art with at-risk students is discussed, laboratory facilities are described, the interaction of students from different grade levels is discussed, and program effectiveness is assessed. (three references) (LRW)

Described is a laboratory experiment designed to expose students to problem-solving methods individually and as a group. Included are background information, a list of materials, laboratory procedures, analysis methods, and probable results. (CW)

Described are teaching methods used to teach measures of central tendency to middle and high school students. Discussed are quantitative and qualitative data, basic experimental terms, a general overview of data analysis, data charts for quantitative data, qualitative data analysis, and extensions for older students. (CW)

Described are two microscale chemistry laboratory experiments including "Microscale Syntheses of Heterocyclic Compounds," and "Microscale Acid-Base Extraction--A Colorful Introduction." Materials, procedures and probable results are discussed. (CW)

Describes a heuristic conceit, "the writer's stance," to help students overwhelmed by the complexity and possibilities of a writing task regain control of the process. Stresses the need for writers to select vantage points and frames of analysis for their academic writings. (SR)

Proposes that ethnography is a useful tool for helping teachers understand the cultural context of their students. Examines a high school writing lab, emphasizing the role of the tutor. Describes the experiences of the writing lab staff in learning the culture of adolescents through ethnography. (RS)

Presented is a technique for making various molecular models from a strip of paper. Instructions for six models including tetrahedral, trigonal bipyramid, octahedral, pentagonal bipyramid, and capped octahedron models are provided. (CW)

Presented is an activity designed to introduce introductory chemistry students to the standard reduction potential table. Included are lists of equipment and reagents, procedures, sample worksheets, and teaching directions. (CW)

Described is an activity based on a fictitious poisoning incident that is designed to challenge gifted and talented high school students. Discussed are the laboratory procedures, reagents, instrumentation, and results. (CW)

Introduced is a sandstone classification scheme intended for use with thin-sections and hand specimens. Detailed is a step-by-step classification scheme. A graphic presentation of the scheme is presented. This method is compared with other existing schemes. (CW)

Three activities involving electromagnetism are presented. Discussed are investigations involving the construction of an electromagnet, the effect of the number of turns of wire in the magnet, and the effect of the number of batteries in the circuit. Extension activities are suggested. (CW)

Presented is an activity designed to teach the use of the scientific method to non-science majors. Collecting, classification, and follow-up activities for a beach trip are discussed. Two simple dichotomous keys are included. (CW)

A procedure for extracting DNA from yeast using common reagents and equipment is given. Suggestions for variations are provided. A second activity for building a model of DNA from toothpicks is included. (CW)

A member of the original faculty of the experimental Ohio State University Laboratory High School reflects at a fiftieth reunion of the first graduating class. Students were used as guinea pigs to determine the effects of providing teenagers with liberating, interesting, and customized education from university faculty. (SM)
