Recently, there has been a rapidly growing trend in non-English-speaking countries for English to be adopted as the medium of instruction in higher education. Consequently, it has become necessary to conduct research that will guide lecturers in effectively adopting (EMI) on campus. This paper presents a blended learning strategy that integrates a…

Learners are usually provided with support devices because they find it difficult to learn from multimedia presentations. A key question, with no clear answer so far, is how best to present these support devices. One possibility is to insert them into the multimedia presentation (canned support), while another is to have a human agent provide them…

Compared performance of low-aptitude remedial adults learning to solve mathematics word problems. Participants worked either alone or as collaborative dyads and received instruction/practice using either the Word Problem-Solving Environment (WPSE), an exploratory system over which learners exercise control, or Solver, a structured and directive…

This study examined the cognitive impact of implementing a computer algebra system (CAS) on six intermediate algebra classes at Orange Coast College (California). The control group of three classes was taught using the traditional method of instruction and scientific calculators. The other three classes were the experimental group and were taught…

The behavior of approximately 50 employees learning to use a Los Alamos National Laboratory personnel information system with fixed-format and context-sensitive online help was monitored between October of 1984 and June of 1985. Data was gathered through direct observation during training workshops and during actual use, logging of consulting…

Describes a computer-based instructional system called Stat Lady and reports the results of an evaluation study of undergraduates that tested the efficacy of learning probability from this program compared to a traditional lecture and a no-treatment control group. Aptitude treatment interaction is also investigated. (Author/LRW)

To date, the majority of computerized adaptive testing (CAT) systems for achievement and aptitude testing have been based on the dichotomous item response models. However, current research with polychotomous model-based CATs is yielding promising results. This study extends previous work on nominal response model-based CAT (NR CAT) and compares…

Reviews empirical studies from a wide variety of fields to show that computer-based multimedia instruction may be able to help people learn more information more quickly compared to traditional classroom lecture. Topics include interactivity; control of learning pace; novelty; and learners with low prior knowledge or aptitude. (103 references)…

Aptitude-treatment interactions (ATIs) refer to the covariation between learner characteristic and instructional treatment in relation to some outcome measure. To systematically test for ATI, an intelligent tutoring system instructing in basic principles of electricity was chosen as a complex but controlled learning task. Two learning environments…

Describes two experiments that were designed to test the effectiveness of a microcomputer-based vocabulary program for high school students. Pretest and posttest methodologies are described for learning-disabled, remedial, and general students, and results for the experimental and control groups are compared. (18 references) (Author/LRW)

Describes a study that investigated a home/school computer project and its effects on reading, language, and mathematics achievement on 142 fourth- and fifth-grade students as well as equity issues relating to gender, academic aptitude, and socioeconomic status. Results indicate that participation was not associated with increased academic…

Investigates the effectiveness of two types of computer feedback: one is traditional computer feedback that indicates only missing or unexpected words in the learner's response, and the other is intelligent computer feedback that provides further information about the nature of the errors in the form of metalinguistic rules. (17 references)…

This study examined the instructional effectiveness of three software learning environments--LOGO, drill and practice, and teacher-directed activities--for preschool special needs children. Cognitive distancing was applied to classify children and child-software interactions; dependent measures included indicators of problem solving, skill…

Describes study of Israeli elementary school students that examined student attitudes toward computer-assisted instruction (CAI) designed to provide drill and practice in arithmetic. Attitudes are compared in relation to students' aptitude, gender, grade level, and socioeconomic status, and implications for the design of CAI systems are discussed.…

Describes study that compared the achievement of high and low ability eighth-grade students working cooperatively during computer-based instruction. Homogeneous and heterogeneous grouping based on ability are explained, posttest results are analyzed, and implications for instructional design are discussed. (23 references) (Author/LRW)
