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)

Describes an inexpensive and versitile interface which can be readily adapted to many on-line experimental projects in scientific fields by educators who are not computer experts. Hardware and software requirements are noted. (JN)

The author presents a brief statement giving reasons for followup studies of teacher problems and explains the procedure for conducting such studies, the instruments used for data collection, and the estimated costs of a follow-up program. The four reasons cited for investigating teacher problems are: (1) to expose teacher educators to current…

Without an efficient, effective data storage and retrieval system, no performance based teacher education assessment plan will succeed. Concepts and techniques fundamental to the establishment of such a system are described. (MJB)

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…

Reviews three functions performed by modern computing integrators: (1) data acquisition; (2) data processing; and (3) communication. Also shows with examples how new electronic components enhance the functions of this popular analytical instrument in those areas. (JN)

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.

This document presents proceedings of a 1976 conference on the assessment of teaching competence in special education teachers. The concerns identified for discussion were: (1) instruments for assessing interpersonal competencies in preservice special education students; (2) instruments for assessing teaching competencies in noninterpersonal…

Constituting part of the final volume of a four volume report on the results of a national study of the Upward Bound (UB) and Educational Talent Search (ETS) programs, the appendixes are comprised of: (1) data collection and preliminary processing procedures; (2) sampling methodology and sampling error computation; (3) instrumentation; (4)…

Describes a system of interfacing allowing a range of signal conditioning and control modules to be connected to microcomputers, enabling execution of such experiments as: examining rate of cooling; control by light-activated switch; pH measurements; control frequency of signal generators; and making automated measurements of frequency response of…

Describes an interface designed to meet the requirements of an instrumentation teaching laboratory, particularly to develop computer-controlled digital circuitry while exploiting electrical drive properties of common transistor-transistor logic (TTL) devices, minimizing cost/number of components. Discusses decoding for Pet, switches, lights, and…
