The Elo rating system has been recognised as an effective method for modelling students and items within adaptive educational systems. The existing Elo-based models have the limiting assumption that items are only tagged with a single concept and are mainly studied in the context of adaptive testing systems. In this paper, we introduce a…

Assessment of groups in CSCL context is a challenging task fraught with many confounding factors collected and measured. Previous documented studies are by and large summative in nature and some process-oriented methods require time-intensive coding of qualitative data. This study attempts to resolve these problems for teachers to assess groups…

The effects on reading speed and comprehension of window proportions and page turning in electronic text were investigated in this study. Subjects--61 undergraduate students at the University of Wisconsin--Whitewater--were administered a standardized reading text displayed as photocopied dot matrix print in simulation of electronic text. There…

This study investigated the effects of course structure variables on the computer anxiety, confidence, and attitudes of college students. Course structure variables include the number of weeks the course met (course length) and the number of meetings per week (course frequency). The effects of differences in instructors' use of anxiety reducing…

This study compared the effectiveness of computer simulation with that of traditional videotaped role playing in a helping skills course for nurses. Subjects were 78 nursing students at the University of Minnesota's School of Nursing who enrolled in a helping relationships course during either the winter or spring quarter of 1987. During each…

This study assessed the effects of varying degrees of elaboration in a prose format using computer-assisted instruction (CAI) with accompanying slides on posttest scores of college age learners. Four instructional treatments were used: control, embedded questions (TR1), computer generated feedback (TR2), and computer generated feedback with a…

This document reports an experiment designed to assess the effects of learner control over the level of challenge in computer-assisted instruction (CAI) and collect data that will guide the design of future learner control experiments. The subjects were 78 undergraduate students in the College of Education at a large public university. The CAI…

The effects of various interactive video instructional control options and practice on learning were examined in this study. The interactive video lesson was a 30-minute videotape designed to introduce cardiopulmonary resuscitation (CPR). Subjects were 48 graduate and undergraduate volunteers, none of whom had prior experience with CPR or…

Purpose: The purpose of this article is to identify and describe existing students' statistical types by their learning strategies and to show the connection with factual computer literacy. Methodology: The empirical-experimental part of the present study is based on a series of diagnostic studies of 1004 surveyed Lithuanian students. The article…

This paper presents a framework for understanding conditions of discovery learning in computer-based microworlds. It begins with a short discussion of problems related to a traditional type of microworld--i.e., learning tools for mathematics--using the Dienes Multibase Arithmetic blocks as an example. In this discussion, hypotheses are developed…

This study investigated the effects of two factors on learner performance during computer-assisted instruction: locus of control, and varied feedback strategies. It was hypothesized that learners who attribute their successes and failures to internal events (Internals) will perform best under delayed feedback conditions, while those who attribute…

Learner and program control of content review within computer assisted instruction (CAI) were studied to determine their effects on the posttest performance and attitudes of eighth grade students. The science-related instructional treatments were completed by 98 students who were blocked by gender and reading ability and randomly assigned to…

Instructional simulation is a type of computer assisted instruction that is effective for teaching dynamic skills. Control of instructional simulation may be fully automated (computer control), assigned to learners (learner controlled instruction), or control may be shared between computer and learner (learner control with advisement). The…

The effects of cognitive and behavioral orienting activities and practice on student learning of cued and uncued information were examined in this study. The subjects were 54 grade 9 students (28 males and 26 females), who were classified as high or low ability based on the verbal intelligence estimate of the Iowa Test of Basic Skills. These…

The purpose of this experimental study was to determine the effects of interactive video versus traditional lecture on cognitive learning and affective behaviors of undergraduate nursing students. It was hypothesized that there would be no significant differences in the cognitive achievement scores of students taught by an interactive videodisk…
