The integration of videodisc technology into the elementary school science classroom is discussed. Stressed are the restructuring of the classroom, creating a positive learning atmosphere, and extending the roles of the teacher and the student. A checklist for successfully integrating videodiscs into the classroom is provided. (CW)

The advantages of the use of videodiscs in elementary school science are stressed. A basic videodisc system is described. Questions to ask before investing in a videodisc system are suggested. Teaching techniques using the videodisc are discussed. (CW)

Presented are two lessons which illustrate acceleration for elementary school students. A poster for use in these activities is provided. Teaching methods used in these lessons are discussed. Student questions concerning automobile racing are presented with answers. (CW)

An interactive computer-assisted learning program written for the BBC microcomputer to teach the basic principles of genetic engineering is described. Discussed are the hardware requirements software, use of the program, and assessment. (Author/CW)

Two designs of undergraduate terrestrial ecology and behavior field courses are described and compared. These include using a variety of projects and using a single individual research project. The relative educational benefits of each are considered and the advantages of each type of course are discussed. (Author/CW)

Presented is a guide for students planning to do a science project. Discussed are preliminary organizational matters, report plans, choosing topics, setting up procedures, time management, and documentation. The most important steps for producing a successful project are summarized. (CW)

Described is a field trip for high school and college students to the country of Belize to study tropical ecology. Discussed are planning and special considerations. Included are a sample schedule and a planning guide. (CW)

Presented is an experiment which can be used in a first-year chemistry class to introduce the synthesis and analysis of compounds. Described are the experimental procedures, sample data, analysis, and discussion. (CW)

Proposed are preparation methods of the active and inactive forms of Cosalen. An experiment of heterogeneous kinetics that consists of following the time dependence of the oxygenation of the active solid and measuring the oxygenation capacity of the chelate is described. (CW)

Described is a case, a heterocyclic sulfoxide, which is useful for an introduction to first-order four-spin data analysis. Background of this technique for use with undergraduate students is given including a sample analysis, a list of supplementary materials, and experimental procedures. (CW)

Procedures for safely identifying, preparing and consuming edible plants in the outdoors are provided. Listed are edible plants, references, sources of recipes, nutrient content, and toxic plants. (CW)

Presents a laboratory experiment which illustrates the formation of tris(phenanthroline)cobalt complexes in the 2+ and 3+ oxidation states, the effect of coordination on reactions of the ligand, and the use of a ligand displacement reaction in recovering the transformed ligand. Uses IR, UV-VIS, conductivity, and NMR. (MVL)

Presents a short reaction sequence that allows the student to determine by spectroscopic methods the constitution and stereochemistry of the reaction products. Reports the interpretations needed to illustrate the usefulness of the spectroscopic method. Notes the products of the Michael-Aldol reaction have not been reported in the literature. (MVL)

Examines the effect of school visits to Nature Reserves. Most students had previous experience with National Parks and environmental media, however, there was a need for basic conservation and management values and ideas to be continually emphasized. (Author/YP)

Presents a picture of the curriculum at the Pullenvale Field Study Centre. The curriculum is based on a drama theme called "The Settlers," and relates to Year Five Social Studies. Describes the curriculum in its current form and its development. Also considers the cyclic process, involving planning, action, observation, and reflection.…
