The jackknife and bootstrap methods are becoming more popular in research. Although the two approaches have similar goals and employ similar strategies, information is lacking with regard to the comparability of their results. This study systematically investigated the issue for a canonical correlation analysis, using data from four random samples…

This Monte Carlo investigation provides some possible solutions to problems related to choosing multiple-comparison methods that maximize true rejections and minimize false ones. It has been argued that the traditional Bonferroni approach to multiple comparisons, which satisfies the statistician's family-wise Type I error concerns, could be…

Reported are the results and conclusions of an arithmetic investigation made in the schools of Scotland in the spring and fall of 1966. The first problem in this investigation was to ascertain which, if either, of two unlike programs of instruction was more effective in developing skill in computation. The second was to determine the value of an…

This brief review lists the major features of teaching machines and programed instruction. The ideal learning situation has these factors: 1) division of the subject into steps small enough to be grasped immediately; 2) specific, clear, sequential questions; 3) means for the student to proceed at his own pace; 4) means of causing the student to be…

Two techniques for writing achievement test items to accompany instructional materials were contrasted: (1) generating items from statements of instructional objectives, and (2) generating items from rules for transforming instructional statements (adapted from Bormuth). Items of each type were written by two experienced item writers. Subjects…

Three commonly used indices of cost-effectiveness are compared for their usefulness to health care professionals. The methods are the cost-benefit ratio, the cost-effectiveness ratio, and the net benefit methods. The net benefit is considered the preferred index of cost-effectiveness. (TJH)

Uses Monte Carlo methods to assess the relative power of the paired samples t test and Wilcoxon's signed-ranks test under 10 population shapes. Concludes that, insofar as these two statistics are concerned, the often-repeated claim that parametric tests are more powerful than nonparametric tests is not justified. (Author/CB)

Critical examination is made of the recent controversy over the value of Monte Carlo techniques in nonmetric multidimensional scaling procedures. The case is presented that the major relevance of Monte Carlo studies is not for the local minima problem but for the meaningfulness of the obtained solutions. (Author)

Four of the most commonly used multiple comparison procedures were compared for pairwise comparisons and relative to control of per-experiment and experimentwise Type I errors when conducted as protected or unprotected tests. The methods are: (1) Dunn-Bonferroni; (2) Dunn-Sidak; (3) Holm's sequentially rejective; and (4) Tukey's honestly…

Author gives specific suggestions to high school teachers; he feels that pairing the two plays offers additional valuable insights into each. (Author/SP)

Humorous comment on library standards, advocating measurement of library efficiency by circulation per square foot. (JS)

Report based on a research paper concerning the use of a transcript as a teaching aid in a beginning shorthand class. (MU)

This article describes an experimental evaluation of training systems in which three kinds of programmed instruction were compared: (1) group-paced, sound-tape, linear program; (2) self-paced, linear, text program; (3) self-paced, adjunct program, manipulation of objects being a component of all three methods."

Explains two main approaches to human resource development (HRD): the transactional, which focuses attention on training as an activity strategy; and transformational, which focuses on a results-driven strategy that is performance-centered and helps organizations achieve strategic business goals and objectives. Compares the role of HRD…

Presents the human evaluation of ILIAD, a program for machine-aided indexing that was designed to assist expert librarians in computer-aided indexing and document analysis. Topics include controlled indexing and free indexing; natural language and concept-based information retrieval; evaluation methodology; syntactic variations; and a comparison…
