Intelligent Tutoring Systems (ITS) are computer-based learning environments that aim to imitate to the greatest possible extent the behavior of a human tutor in their capacity as a pedagogical and subject expert. One of the major challenges of these systems is to know how to adapt the training both to changing requirements of all kinds and to…

Introduction: The aim of this study was to analyze the relationship between sociometric types, behavioral categories and self-attributions for academic failure ("Ability", "Effort" or "External Causes") in "Reading", "Mathematics" and "General". Method: The total sample was composed of…

Expressions for the expected value, density, and distribution function (DF) of GS (gain from selection) are derived and studied in terms of sample size, number of predictors, and the prior distribution assigned to the population multiple correlation. (Author/RK)

A discussion of an efficient assignment plan for the domain-referenced testing program to govern how examinees encounter the items. (Author)

Item correlations performed between student ratings of instruction in various situations clearly indicate that student ratings are consistent across time, but that this consistency is related to specific educational settings and conditions as well as instructor idiosyncracies. (RC)

First purpose of this study was to investigate empirically the accuracy of prediction using regression weights selected through the use of variance-reduction procedures. (Author)

This report investigates the selection of appropriate texts for C-Tests, a modified form of the cloze test, for assessing second language learning. The procedure for textbook readability first involved the administration of different texts to sample groups to determine the C-test difficulty of individual texts. At the same time, a variety of…

A linear regression model was used to select items from a pool of 700 arithmetic word problems to be used in a computer-assisted mathematics curriculum for elementary school students. The experimental procedure first involved a stepwise linear regression analysis of a student's performance over a set of 25 problems. The probability correct for…

Data were collected on 80 diverse items concerning student perceptions of teaching for a representative sample of 189 classes at a large university. The items were subdivided by type of focus into four categories: course content, objectives, and structure; instructor's behavior; instructional methods and materials; outcomes of instruction. The…
