More and more faculty members are using web-based instruction as part of their course or as complete courses, which has resulted in an entire web-based instruction programs and virtual universities. As such, web-based instruction is one of the major areas that are becoming key to the development of the Web. To the contrary, despite having…

Variables and conditions that influence the learning of computer-presented expository text were investigated in this study, in which on-screen underlining was used as a learning aid to increase "mindful" processing of information. The effects of three intervening variables--amount of invested mental effort (AIME), learning style, and…

Two papers on "fag(sprog)lig Kommunikation"--languages for special purposes (LSP)--are presented. The first paper, in Danish, presents an alternative to the current structuralist oriented approach to the analysis of LSP as a kind of language in its own right and of texts written in this special kind of language. The approach is based on a more…

Thirteen classroom activities designed to provide active language practice for students of English as a second language are described. Some highlight a targeted grammatical structure, and others require that students work together to solve a problem. Each is designated by level of difficulty (beginning, intermediate, or advanced), skill focus…

This report explores an approach to item development and psychometric modeling which explicitly incorporates knowledge about the mental models used by examinees in the solution of items into a psychometric model that characterize performances on a test, as well as incorporating that knowledge into the item development process. The paper focuses on…

The vocabulary used in textbooks and standardized tests for English as a second language (ESL) is examined to determine how much variation exists. Word lists were compared for six difficulty levels in five frequently-used ESL textbook series (a total of 30 books). Three series of standardized proficiency/placement tests at different levels were…

Multidimensional item difficulty (MID) is proposed as a means of describing test items which measure more than one ability. With mathematical story problems, for instance, both mathematical and verbal skills are required to obtain a correct answer. The proposed measure of MID is based upon three general assumptions: (1) the probability of…

A Monte Carlo study of five indices of dimensionality of binary items used a computer model that allowed sampling of both items and people. Five parameters were systematically varied in a factorial design: (1) number of common factors from one to five; (2) number of items, including 20, 30, 40, and 60; (3) sample sizes of 125 and 500; (4) nearly…

Specific questions addressed in this study include how time limits affect a test's construct and predictive validities, how time limits affect an examinee's time allocation and test performance, and whether the assumption about how examinees answer items is valid. Interactions involving an examinee's sex and age are studied. Two parallel forms of…

The work presented in this paper defined conceptually the concepts of multidimensional discrimination and information, derived mathematical expressions for the concepts for a particular multidimensional item response theory (IRT) model, and applied the concepts to actual test data. Multidimensional discrimination was defined as a function of the…

The effects of feedback about the ratings of other judges on subsequent ratings using the Nedelsky method and the ability of judges to retain or eliminate options in a manner consistent with the judgments of minimally competent examinees were studied using data from a basic algebra examination administered to 227 college students in 1987. The…

The South Pacific Commission's English reading curriculum, designed to accompany and reinforce the Tate English oral skills series, is critiqued in terms of curriculum design and implementation in schools in the Micronesian region. The construction and emphases of the classroom and teacher materials are described, and an analysis is given of the…

Instructional sensitivity indices are compared from four perspectives: (1) criterion-referenced testing; (2) classical test theory; (3) item response theory; and (4) Bayesian theory. Instructional sensitivity is defined as the tendency of a test item to vary in difficulty as a function of instruction. The instructional sensitivity of the items in…

Questionnaires were completed by 62 college professors in a study to determine the specific reading and listening comprehension difficulties students were having in various introductory courses (including humanities, natural and social sciences, and the technical professions), and to determine the instructional techniques used by professors to…

This study examined the difficulty level of essay topics used in the large-scale assessment of writing in relation to five different scoring models, and sought to determine what effects the scoring models would have on passing rates. In model one, examinee's score is the direct result of a score assigned by the reader or the sum of scores assigned…
