Describes the individualized, self-paced format for math instruction provided at Pima Community College's Math Center as an alternative to the traditional lecture method. Examines course offerings, as well as registration, attendance, and grading procedures. Discusses staff organization at the center and the problems of using student tutors. (JP)

Described is Xavier University of Louisiana Piagetian-based general chemistry program. Laboratory experiments are in the learning cycle format and place emphasis on learning by doing. Aspects of the curriculum described include synopses of content covered, laboratory-preceding lectures, list of laboratory experiments covered, and evaluation of the…

Describes a number of laboratory experiments using woodlice as experimental animals. Includes topics such as physiology of water relations, behavior, and rhythmic activity. (CS)

Describes methods for collection, culture, observation, and making permanent stained preparations of the protozoan vorticella. Suggestions are made for experiments to investigate growth, reproduction, settlement, ecology, feeding, and osmoregulation. (CS)

By means of the Kay Elementrics Visi-Pitch and a split screen, students are able to compare their voice traces with the model's, thereby seeing prosodic, phonemic, and allophonic distinctions they were unable to hear. (PMJ)

An interdisciplinary physiology and pharmacology course presented by the Medical Interaction Laboratory at the University of Tennessee College of Veterinary Medicine provides interaction among faculty, conserves faculty time and animal expense, and presents a coordinated laboratory experience. (BH)

Describes a dental teaching strategy that promotes acquisition of psychomotor skills through use of metacognition and problem-solving. In five steps, questions are asked to guide the learner through a sequence of discriminations leading to recognition of problems and solutions. Clearly defined criteria in a sequence reflecting procedure are…

Uses base-year data from a nationally representative database (NELS:88) to identify important explanatory factors for gender differences in science performance. Documents a large advantage for boys on the subtest of physical science and a modest advantage for girls in life science. Concludes that laboratory experiences are beneficial for girls'…

Evaluates the effectiveness of lexical-field instruction for intermediate level English-as-a-Second-Language students in a language laboratory setting. Findings reveal that the lexical-field instruction is an effective procedure for teaching general language knowledge through the meaning system. (45 references) (Author/CK)

Analyzes undergraduate research projects in biochemistry and related subjects at British universities. Discusses the trend toward students doing less research as part of their undergraduate study. Reasons cited for this trend include increased student numbers and costs. (DDR)

Describes results of a computer use survey of 210 graduate programs in educational administration throughout the United States and Canada. Highlights include specific types of computer hardware used in the past, types that are expected to be used in the future, computer lab access, and implications for resource allocations for microcomputers.…

Included are 30 science activities that include computer monitoring, fieldwork, enzyme activity, pH, drugs, calorimeters, Raoult's Law, food content, solubility, electrochemistry, titration, physical properties of materials, gel filtration, energy, concepts in physics, and electricity. (KR)

Discussed are experiments that may be done using a microcomputer to analyze scattering data. Apparatus assembly, procedures, and results for this activity are presented. (CW)

Four microcomputer applications are presented including: "Computer Simulated Process of 'Lead Optimization': A Student-Interactive Program,""A PROLOG Program for the Generation of Molecular Formulas,""Determination of Inflection Points from Experimental Data," and "LAOCOON PC: NMR Simulation on a Personal Computer." Software, availability,…

Examined are applications of computer spreadsheets from simple record/observation tables to custom built analysis systems. The advantages and disadvantages depending on the use of these software packages are discussed. Several examples are used to illustrate possible applications. (CW)
