Effects of two feedback conditions--comment and no comment--on the motivation of sixth grade students to continue with computer assisted instruction (CAI) were investigated, and results for boys and for girls were compared. Subjects were 62 students--29 boys and 33 girls--from a suburban elementary school who were randomly assigned to the comment…

In order to determine the effectiveness of multidimensional scaling (MDS) in recovering the dimensionality of a set of dichotomously-scored items, data were simulated in one, two, and three dimensions for a variety of correlations with the underlying latent trait. Similarity matrices were constructed from these data using three margin-sensitive…

The purpose of this research was to reinvestigate the accuracy of three item bias detection procedures: (1) Linn and Harnisch's pseudo-IRT(Z) method; (2) Camilli's chi-square technique; and (3) Angoff's revised transformed item difficulty method. These methods are applied when the minority group sample size is too small to obtain stable estimates…

An online library system is an example of a complex computer system in that it supports a variety of users, both patrons and staff, and is made up of many intricate programs with complex relationships among them. Certain features are essential to a user friendly system: (1) users cannot get lost in the system; (2) users cannot enter illegal…

A study investigated correlations between students' and parents' attitudes toward the Hebrew language, students' attitudes and achievement in Hebrew, attitude differences in boys and girls, and attitude differences of students in the third and fourth years of Hebrew study. Parents and students in four Chicago-area supplementary Hebrew schools were…

In order to accurately assess the learning of vocabulary words, a criterion of learning achievement must be set for each word or group of words. This criterion would reflect: (1) the amount of semantic, grammatical, and phonological information the learner had to possess in order to have learned the word; (2) the receptive and productive processes…

It is important to estimate the number of examinees who reached a test item, because item difficulty is defined by the number who answered correctly divided by the number who reached the item. A new method is presented and compared to the previously used definition of three categories of response to an item: (1) answered; (2) omitted--a…

This study examines two kinds of French language tests originating from the Threshold-Level (T-Level) or Niveau-Seuil theory of language learning in the context of several linguistic and testing concepts: discrete-point testing with regard to notions and functions from T-Level theory, communicative context, and assessment of listening…

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…

This paper deals with test fairness regarding a test consisting of two parts: (1) a "common" section, taken by all students; and (2) a "variable" section, in which some students may answer a different set of questions from other students. For example, a test taken by several thousand students each year contains a common multiple-choice portion and…

Oral production (the speech act) and the comprehension of written and oral texts have long been treated as separate entities when they could be used in an integrated approach to teach a broader range of language skills. The receptive aspects of the speech act should be brought into language instruction and used to select materials for teaching…

A study attempted to estimate the instructional sensitivity of items in three reading comprehension tests in English as a second language (ESL). Instructional sensitivity is a test-item construct defined as the tendency for a test item to vary in difficulty as a function of instruction. Similar tasks were given to readers at different proficiency…

A study examined the effects of formal and informal learning environments on the storage and recall of lexical items in the first and second languages, paying specific attention to laterality and accuracy rates for tasks of varying difficulty. The study used the dichotic listening task and subjects whose first language was English and whose second…

Difficulty and discrimination ability were compared between multiple choice and short answer items in midterm and final examinations for the internal medicine course at Louisiana State University School of Dentistry. The examinations were administered to 67 sophomore dental students in that course. Additionally, the impact of the source of the…

This paper considers the feasibility of incorporating research results from cognitive science into the modeling of performance on psychometric tests and the construction of test items. The paper focuses on the feasibility of modeling performance on a three-dimensional rotation task within the context of Item Response Theory (IRT). To test the…
