Ideas related to including ethology in high school biology programs are given. The methods of ethology and tips on how to communicate observations are briefly explained. (SA)

This paper, presented at the conference on the role of the laboratory in physics education which was held in Oxford, England in July 1978, describes how a Malaysian University has presented electronics and the laboratory work as a forced component in physics curriculum. (HM)

Described is an advanced undergraduate laboratory experiment in which radio-frequency transitions between molecular hyperfine structure states may be observed. Aspects of the quantum theory applied to the analysis of this physical system, are discussed. (Authors/BT)

This experiment is intended as a classroom demonstration. It describes the preparation of materials, the procedure, and a few remarks related to demonstrating travelling waves of chemical activity in the Zaikin-Zhabotinskii-Winfree Reagent. (SA)

Describes seven creative laboratory activities appropriate at any grade level (K-12) that stress the method and spirit of scientific inquiry. (CS)

Recommends a constructivist approach to physics laboratory activities to make laboratories a place for personal maturation and cognitive growth. Describes class design in which ideas and techniques are exchanged which allow students the opportunity to initiate investigations based on early conceptual assumptions, and extend the investigation…

Describes four hands-on and inexpensive activities science teachers can employ to demonstrate, encourage, develop, and teach students the physical properties of light, heat, and sound waves, utilizing a coffee can. Details the basic experiments and provides additional information for tailoring the activities to elementary through middle…

Describes a titrator system, constructed from a computer-interfaced pH-meter, that was designed to increase student involvement in the process. Combines automatic data collection with real-time graphical display and interactive controls to focus attention on the process rather than on bits of data. Improves understanding of concepts and…

Describes a course specifically designed to allay the fear of science in elementary teachers by teaching them science in a laboratory-activity setting. Provides valuable laboratory experience often lacking in general education science courses. Lists topics covered in guided discovery exercises. Contains 12 references. (JRH)

Describes the use of videotapes to introduce experiments in a first-year undergraduate physics laboratory and investigates the effects on students' attitudes and achievement. Concludes that students responded positively to the video introductions but student performance was not improved. Discusses other positive outcomes of the videos. Contains 12…

A teacher of gifted minority children explains how to conduct a hands-on science experiment investigating how many drops of water can fit on a penny. Four different student activities that teach concepts such as the necessity of controlling variables in scientific experiments are described. (CR)

Describes an investigation of the associations between students' perceptions of laboratory environment and their attitudinal, cognitive, and practical performance outcomes. Assesses student outcomes in three distinct areas: (1) student attitudes; (2) achievement on a written examination; and (3) practical performance, specifically in the biology…

Describes the use of mud dauber wasp nests in laboratory activities in ecology and behavior and life science classes. Provides students with an opportunity to develop and practice basic skills including dissection, identification, observation, measurement, and communication. Discusses the life of mud daubers, obtaining and storing nests,…

Presents a protocol that gives students hands-on experience in generating a meaningful physical map of a circular molecule of DNA. Topics include agarose gel electrophoresis, logic of restriction maps, extracting data from an agarose gel, managing data from gels, experimental protocol, loading gels, electrophoresis, photographing gels, collecting…

This article lists 23 comprehensive Web sites related to providing differentiated instruction to gifted students. It also discusses overall areas of differentiation, including modifying content, altering the pace of instruction, creating a flexible classroom environment, and using specific instructional strategies.
