Describes a study that compared computer-assisted instruction (CAI) and a more traditional paper-and-pencil method in teaching mathematics skills to elementary school students with and without mild mental handicaps. Pretests and posttests were analyzed, and it was found that CAI, and extended practice, enhanced automatization of mathematics skills. (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)

Challenges the assumption that contextualized vocabulary learning invariably leads to superior retention. The article compares two different instructional treatments in a university classroom experiment in China in the teaching of English as a foreign language: the study of contextualized versus decontextualized English word lists. (40 references) (Author/CK)

Describes a study that investigated the effects of learner control and program control, and lean and full modes of instructional programs, on the achievement, use of options, time on task, and attitudes of high-ability and low-ability students from grades 9 and 10 during computer-assisted instruction. (LRW)

Describes a study of graduate students that examined search behavior and affective response to a hypertext-based bibliographic information retrieval system called HyperLynx for searchers with different search skills and backgrounds. Previous experience with hypertext or Boolean searching is examined, and search times are discussed. (21 references) (LRW)

This study investigated the effect of using computer-mediated reading supports on the reading comprehension and reading behavior of beginning learners of Arabic as a foreign language. Recommendations for future research are given as well as theoretical and pedagogical implications for second-language instruction. (eight references) (LRW)

Describes a study conducted at the University of West Florida with the Navy that investigated the effects of cooperative tutoring on academic performance. Treatments for the experimental and control groups are described, and performance based on cognitive style as determined by scores from the Group Embedded Figures Test is discussed. (24 references) (LRW)

Describes two experiments that were conducted at the University of Illinois to determine how cognitive abilities of users of information retrieval systems and specific design features combine to create system usability. Logical reasoning and perceptual speed are examined, and reliability and validity are discussed. (Contains 12 references.) (LRW)

The alternative proposed by Wilcox (1989) to the James second-order statistic for comparing population means when variances are heterogeneous can sometimes be invalid. The degree to which the procedure is invalid depends on differences in sample size, the expected values of the observations, and population variances. (SLD)

Discussion of school effectiveness, achievement outcomes, and sociocultural influences focuses on a study of Nigerian high school students that was conducted to determine whether or not instruction based on a sociocultural model could significantly alter students' attitudes toward learning and achievement in science. (51 references) (LRW)

Discussion of indexing needs for film and video images focuses on appropriate access points for the storage and retrieval of individual shots which have not yet been included in a production. A study at the National Film Board of Canada is described that investigated ways to index non-art images. (18 references) (LRW)

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)

Based on interview and survey data from 220 upper- and middle-level managers within a Fortune 500 manufacturing firm, this case study describes how differences in organizational values influence the frequency with which decision makers use oral, written, and electronic sources of information for environmental scanning. (91 references) (LRW)

Describes a study that examined the accuracy and type of preservice teacher feedback to computer-simulated pupils. Accurate and inaccurate feedback when focusing on the accomplishments and deficiencies of the simulated pupils is examined, and patterns linking teachers' assessment of pupil performance with feedback during lesson interactions are studied. (Author/LRW)

Describes a study that was conducted to determine whether distance education learners experience anxiety, based on results of a survey of 222 University of Southern Queensland students. Anxiety toward instructional materials and variables that affect students' perceptions of factors that affect their anxiety are discussed. (LRW)

Investigates a complex aptitude treatment interaction (ATI) of intelligence and metacognitive skill as aptitudes with structuredness of learning environment as treatment, based on a study of undergraduates in simulation environments. Highlights include computer-assisted learning and experiential learning; ATIs and discovery learning; and learning measures. (Author/LRW)

Discussion of locus of control (LOC), gender, and mathematics and technical subjects focuses on a study of preschool girls and boys that investigated the effects of a LOGO program on efficacy and LOC. Highlights include treatment of experimental and control groups; gender differences; parent questionnaires; and pretests and posttests. (69 references) (LRW)

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)

Describes a study that examined the effect of family socioeconomic status (SES) and parental sex stereotypes and behaviors on high school students' attitudes toward computers. Highlights include gender differences in student attitudes; the effect of parental encouragement; and the effect of SES on parents' beliefs and behavior. (68 references) (LRW)

Describes a study that was conducted at Tilburg University (The Netherlands) to test the impact of system and domain knowledge on search behavior in an online catalog. Highlights include time spent on task; the number of search patterns performed; and search patterns used most frequently. (11 references) (LRW)

Discussion of the design of computer menus focuses on two experiments that examined task time across several orderings of menu lists. Findings are described that demonstrated that good physical layout in screen design is not sufficient without good conceptual layout. The size of menu lists for maximizing efficiency is considered. (Contains 17 references.) (LRW)

Describes a study that investigated the effect of motivational variables on task persistence and performance in Navy technical training by giving students problems in a self-paced computer simulation game or drill with variable or fixed payoff points. Student responses to an evaluation questionnaire are discussed. (14 references) (LRW)

Describes a study of teacher education students at West Virginia University that was conducted to determine the effects of a computer-awareness learning module, instructional format, and prior computer use on computer anxiety. The relationships among performance, computer anxiety, and prior experience are also discussed. (Contains 12 references.) (LRW)
