The device described is a system to indicate left-to-right head position. It is limited to indicating relative left-right movements without vertical or up-down discrimination. Although developed for newborns, the system can be applied to older subjects by using a holding device for the infant. (JH)

The need for experimental schools is discussed; also a description of one such school and of its activities is presented. (CK)

The present study examined the effects of equivalence test order and nodal distance on the emergence and stability of derived discriminative stimulus functions. Participants in 1 group were exposed to a transfer of functions test following a symmetry and equivalence test, another group of participants completed a symmetry and equivalence test…

A biochemistry laboratory class protocol is described in order to create an opportunity for students to apply by doing the theoretical concepts underlying biomolecules and vesicles properties, together with the principles of centrifugation and colorimetric methodologies. Through simple procedures the students will i) observe the segregation of the…

This teacher's guide was developed for use in junior and senior high schools in Duval County, Jacksonville, Florida, for the purpose of identifying those secondary science laboratory experiences which are essential to the development of science content knowledge and competency in handling science laboratory equipment and consumables. The guide…

We propose a new paradigm for building a Management Information Systems course that focuses on laboratory activities developed collaboratively using Computer-Mediated Communication and Collaboration tools. A highlight of our paradigm is the "practice what you preach" concept where the computer communication tools and collaboration…

Three classrooms of Grade 4 students from different schools and diverse backgrounds collaborated in early algebra research to solve a series of linear and quadratic generalizing problems. Results revealed that high- and low-achieving students were able to solve problems of recognized difficulty. We discuss Knowledge Building principles and…

A Clemson University introductory landscape design class collaborated with South Carolina Botanical Gardens (SCBG) staff and coordinators of Sprouting Wings to design an exploratory Children's Garden within the SCBG. Service learning provides students with invaluable real-world experiences solving problems and interacting with clients while…

As part of an experiment, a three quarter sequence in organic chemistry was designed to be accompanied by laboratory experiments that reinforce the lecture material and encourage independent investigation by minimizing cookbook-style procedures. By having laboratory techniques explained in detail on video casettes, students were exposed to uniform…

Design factors in the planning of research laboratories are described which include--(1) location, (2) future expansion, (3) internal flexibility, (4) provision of services, (5) laboratory furnishing, (6) internal traffic, (7) space requirements, and (8) building costs. A second part discusses air-conditioning and conditioned rooms--(1)…

Volume I of a two volume manual serves as an introduction to design criteria for microbiological facilities. It is addressed to management personnel responsible for planning, budgeting, and making policy decisions for construction or remodeling of microbiological research laboratories. This volume is also concerned with--(1) microbiological safety…

Factors for the planning of functional, economical and safe laboratory facilities are discussed, with emphasis on the economical results of planning for a specific purpose and for the specific needs of each occupant. A questionnaire is suggested as a useful tool for determining requirements. Other areas for consideration include--(1) laboratory…

Describes an experiment involving pineapples and gelatin that allows students to investigate the conditions that typically render an enzyme functionless, similar to the effect of nerve gasses. Discusses the materials, procedures, and results, drawing analogies to the effects of a nerve gas. (CW)

Describes an apparatus capable of measuring absolute temperatures of a tungsten filament bulb up to normal running temperature and measuring Botzmann's constant to an accuracy of a few percent. Shows that electrical noise techniques are convenient to demonstrate how the concept of temperature is related to the micro- and macroscopic world. (CW)
