This quarterly publication includes articles concerning the advancement, improvement, and coordination of science education in all fields of science at all educational levels. In this issue, articles deal with science resources, physics teacher workshops, environmental education programs, laboratory equipment and instructional aids, and…

College and university learning centers have evolved from narrowly defined remedial services to agencies serving the entire student community. The changing role of learning centers necessitates systematic program evaluation and assessment of student needs. During 1975, the Colorado State University Learning Laboratory staff collected data on…

Investigated how the use of laboratory-oriented science curriculum materials affected the attitudes of students with reading difficulties. Both the ninth grade experimental and control classes used a six-week instructional unit on heat and temperature. (HM)

Presents task analysis of the laboratory inquiries of the BSCS Yellow Version. Three important deficiencies are identified: (1) Students do not identify and formulate problems; (2) Students get little chance to conduct investigations; and (3) Post-laboratory discussions are not indicated. (MA)

A description of a method of designing pattern drills for use in the laboratory which will not only keep students alert but will also provide meaningful contexts. The use of drill-oriented drawings and multiple operation exercises is analyzed. (AMH)

Trace organic analysis (TOA) is seen as a more useful way to quantify environmental pollutants. Current practices and future trends are discussed in detail. Seven steps in TOA are identified: collection, storage, extraction, concentration, isolation, identification, and quantification. (MA)

Attainment of laboratory course objectives was compared for tenth and twelfth grade Israeli students using two chemistry curricula: An Experimental Chemistry Program for Secondary Schools (ECPSS) and the CHEM Study program. ECPSS students more often than non-ECPSS students, and ECPSS girls more often than boys felt they had achieved the…

At north Arundel Vo-Tech in Maryland a well-organized safety program involves the entire school staff--plus Maryland Occupational Health and Safety Act. Strict enforcement of safety violations keeps everyone safety conscious--including the administration and custodial staff. (Editor/HD)

Presents an analytical or inorganic chemistry laboratory experiment in preparing nickel macrocyclic complex. (SL)

Points out the health and legal implications related to laboratory substances that could cause allergic reactions. Presents a list of potential cosmetic allergens and irritants. Includes precautionary measures dealing with allergy situations. (ML)

Describes how a Polaroid camera can be modified for spectroscopic experiments. Reviews experimental procedures and discusses results that students can obtain within one normal laboratory period. Suggests additional experiments for investigating emission from other sources. (ML)

Proposes a series of experiments that integrate analytical techniques in order that students are able to compare, based on their laboratory results, the relative reliabilities of the most common therapeutic drug monitoring methods. Discusses materials, procedures, and results of three experiments on the determination of drug concentration by…

Discusses the role of the fruit fly in genetics research requiring a multidisciplinary approach. Describes embryological and genetic methods used in the experimental analysis of this organism. Outlines the use of Drosophila in the study of the development and function of the nervous system. (RT)

Describes three methods and their advantages and disadvantages for introducing genes into animals. Discusses the predictability and tissue-specificity of the injected genes. Outlines the applications of transgenic technology for studying gene expression, the early stages of mammalian development, mutations, and the molecular nature of chromosomes.…

Explanation of the purpose of microcomputer simulations in history classes at the college or secondary school level focuses on the development of one simulation, The American Revolution. Highlights include effects on learning processes of using simulations in a microcomputer laboratory; student evaluations of the simulation; and creation of the…
