Presented is a three-hour instrumental analysis experiment which allows study of software data-handling methods. These methods include sampling, boxcar averaging, smoothing, ensemble averaging, and digital filtering. Use of the program should provide students with a better idea of advantages and disadvantages of using such software data-handling…

Discusses how computational errors arise in analysis of data and how they can be minimized. Shows that all computations are subject to roundoff/truncation errors and how such errors are propagated and influence the stability and condition of a reaction. Applications to procedures used in analytical chemistry are addressed. (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…

A gas chromatography (GC) mass spectroscopy (MS) system recently developed by Hewlett-Packard (HP-5987 GC/MS/Data System) is described, illustrating the technological advances that have been achieved with the system. Examples of the data processing and output process are provided to demonstrate the capabilities and application of the system to…

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)…
