Discusses various topics related to the interfacing of computers, focusing particularly on methods of data collection using instruments. Topics include serial digital connections (examining RS 232C and V.24, physical protocol, electrical protocol, and other areas) and parallel digital connections. (JN)

Reviews background of atomic absorption spectrometry techniques. Discusses problems encountered and precautions to be taken in determining trace elements in the parts-per-billion concentration range and below. Concentrates on determining chromium in biological samples by graphite furnace atomic absorption. Considers other elements, matrices, and…

Focuses on attributes of microcomputer systems which affect their usefulness in a laboratory environment. In addition to presenting general concepts, comments are made regarding the implementation of these concepts using a microprocessor-based data acquisition system developed at the University of North Carolina. (CO)

Stresses providing reliable, factual information directly to users. Describes classes of data, the need for good data, quality control of databases, the electronic revolution in data dissemination, systematic cooperation to reduce costs of developing online services and of creating data bases, and trends in data dissemination. (JN)

Emphasizes the unique advantages of computer-mediated communication (CMC) for teaching genetics. CMC allows students to collect larger sample sizes than other methods and from any part of the world in a very short time. Describes hardware and software requirements, useful tools and techniques, and a sample project on human genetics for a…

Offers some strategies for enabling science teachers to make better use of data-logging methods. These ideas are grounded in the belief that science teachers are expert lesson planners. Benefits gained for students using data-logging techniques are more likely to be secured through teachers re-interpreting their planning approaches in the new…

Discusses the use of computers for nine different tasks in biological education: information retrieval, data accumulation, data analysis, simulation and systems analysis, decision making, experimental control, course review, computer-managed instruction, and word processing. (PEB)

Running experiments and grabbing experimental data are great ways to learn and teach science and mathematics. Data grabbers are instruments that capture physical data in electronic form for graphing and analysis in graphing calculators and computers. Describes some data grabbers and points to items in their gigantic support system. (PVD)

This report reviews 5 years of work involving the Parent Empowerment Project (PEP) and also examines the results of a study that was undertaken to plot the changes in school performance of at-risk children and youth that have occurred since their parents became involved with PEP. It includes: (1) a summary of the demographics and characteristics…

This report provides a summarized version of a larger study conducted by the Office of Technology Assessment concerning the choices that Congress and the executive branch must make in supporting U.S. science and engineering. The summary first discusses the report's origins; trends in federal research funding; and a look at federally funded…

This report analyzes what the Office of Technology Assessment (OTA) identifies as four pressing challenges for the Federal Research System in resource allocation and funding for research in the 1990s: (1) setting priorities in funding; (2) understanding trends in research expenditures; (3) preparing human resources for the future research work…
