An integrated accessible microscopy workstation was designed and developed to allow persons with mobility impairments to control all aspects of light microscopy with minimal human assistance. This system, named AccessScope, is capable of performing brightfield and fluorescence microscopy, image analysis, and tissue morphometry requisite for…

Malathion is an organophosphorus insecticide, which is often sprayed to control mosquitoes. When applied to aquatic habitats, malathion can also influence the embryogenesis of non-target organisms such as frogs and fish. We modified the frog embryo teratogen assay in "Xenopus" (FETAX), a standard toxicological assay, into an investigative…

In this article, the author describes three reports conducted by the National Academies, a private, nonprofit organization whose charter is to assist the federal government and the American people in analyzing pressing science and technology policy issues. These reports are: (1) "Rising Above the Gathering Storm: Energizing and Employing…

Data sharing among multiple lab sections increases statistical power of data analyses and informs student-generated hypotheses. We describe how to collect, organize, and manage data to support replicate and rolling inquiry models, with three illustrative examples of activities from a population-level biology course for science majors. (Contains 1…

A single-semester elective combines Mendelian and molecular genetics in a problem-solving format. Students encounter a genetic disease scenario, construct a family pedigree, and try to confirm their medical diagnoses through laboratory experiences. Encouraged to generate ideas as they test their hypotheses, students realize the importance of data…

For many, the dominant model of curriculum development in science includes generating a topic, clarifying science content, identifying activities associated with the topic, and figuring out an assessment. Unfortunately, this approach tends to overemphasize activities and underemphasize mastery of science concepts and the process of scientific…

This document reports a project, entitled Workshop Physics, that involved the development and testing of introductory physics materials to enable instructors to abandon the traditional separation of lecture and laboratory in favor of a workshop format. The Workshop Physics courses emphasize cognitive development enhanced by direct experience and…

This document is written to encourage college faculty to use a student-centered, activity-related, approach to science instruction. Suggestions are provided for methods that can be used by faculty and administrators to develop alternatives to lecturing. The major sections of this document include the following: (1) Is There an Alternative to…

This study summarizes data collection activities associated with the first two years of a large scale project involving teachers of science and mathematics with computers. The innovation being implemented in the project is that of using computer based strategies directly in the teaching of science and mathematics in the classroom and laboratory.…

Presented is the first in a series of four hearings on international cooperation in science. The focus of the hearing is international cooperation in big science, as personified by the field of high energy physics. The particular area of interest is the questions: What are the past experience and future prospects for international costsharing of…

This study investigated the contributions of the professional qualification of biology teachers, laboratory facilities, and biology textbooks to the teaching of biology in 10 government and 10 harambee schools in Kenya. Biology is currently a compulsory subject in all secondary schools in this country. Data were obtained from questionnaires…

This report presents priorities for new facilities and new capabilities at existing facilities with initial costs of at least $5 million. The new facilities in order of priority are: (1) a 6 GeV synchrotron radiation facility; (2) an advanced steady state neutron facility; (3) a 1 to 2 GeV synchrotron radiation facility; and (4) a high intensity…

This report by the Automation in the Medical Sciences Review Committee of the National Institute of General Medical Sciences, National Institutes of Health, assesses the current status of medical laboratory science and identifies specific areas in need of further development. (CS)

A three-year research effort was conducted to design a crime laboratory proficiency testing program encompassing the United States. The objectives were to: (1) determine the feasibility of preparation and distribution of different classes of physical evidence; (2) assess the accuracy of criminalistics laboratories in the processing of selected…

Presented is an evaluation of a leadership training program to prepare junior high school teachers to use the Introductory Physical Science Curriculum. Emphasis of the leadership program is on administrators and their problems, leaders and their problems, and teachers. Recommendations are given. Included in the appendices are sample letters of…
