Examines changes which have occurred in the development and evaluation of intelligent tutoring systems (ITSs), speculates on future directions, and proposes a conceptual model for the development of ITSs. Topics discussed include the effectiveness of ITSs; the need for multidisciplinary efforts; and internal and external evaluation. (Contains 78…

Describes a study of undergraduates that compared the effects of response-certitude adaptive and nonadaptive feedback in a computer-based lesson of verbal information and defined concept tasks. Effects on student performance, feedback-study time, and lesson efficiency are discussed, and implications for future research are suggested. (LRW)

Discussion of performance assessment focuses on a study that was part of the International Evaluation of Achievement of computer education that tested students in grades 8 and 11 on word processing performance tasks. Results are examined to determine the useability, reliability, and validity of the process. (eight references) (LRW)

Data from a national survey of microcomputer uses in schools are used to demonstrate differences in access to and uses of computers by students. Factors examined include race, socioeconomic status, sex, achievement, and ability level. Also discussed are inequality and inequity and the need for additional research on computer impact. (RP)

Describes a study that examined the impact of computer-assisted instruction developed in the United States on the reading and math performance of students in Grenada. Results were compared with students receiving conventional instruction for high and low ability students and for gender differences. (Contains seven references.) (LRW)

Describes a study of fifth graders that investigated whether types of revision and quality of writing vary for bilingual and monolingual students when using word processors as compared with paper and pencil. Topics discussed include keyboarding skills, bilingualism, and language art skills. (Contains 27 references.) (LRW)

Describes longitudinal studies conducted at the Drexel Early Childhood Center (Pennsylvania) that used Self-Controlled Interactive Learning Systems to teach reading skills. Standardized test scores for at-risk students are compared with other students; experimental and control groups using standard instruction are compared; and studies of…

Describes a study that investigated the effects of computer and noncomputer environments on fifth- and sixth-grade students' learning of geometric motions. The use of LOGO and the treatment of experimental and control groups are discussed, and the results of immediate and delayed posttests are reviewed. (38 references) (LRW)
