Describes a study of 107 sixth graders that investigated the effects of learning strategy training intervention and the incorporation of learner control on achievement, learning efficiency, and instructional choice while subjects learned from a computer-based science tutorial. Principles for instructional design incorporating learner control are…

Describes a study of undergraduates at Iowa State University that tested the effectiveness of a computer simulation of electric circuits used in combination with a conceptual change approach to science instruction. Erroneous preconceptions of scientific concepts are discussed, and the use of traditional text is compared with conceptual change…

The 338 14-year-olds who participated in a study to determine effects of pictures on readability of science topics completed a cloze test during the study and an objective items recognition test afterwards. Posttest scores showed pictures made topic easier to remember although they had little effect on cloze test results. (MBR)

Describes study that was conducted to examine the effects of animation and practice on factual and application learning in elementary science computer-based instruction (CBI). The extent to which animation and practice promoted near and far transfer of learning outcomes is explored, and effects on processing time are examined. (31 references) LRW)

This study investigated relationships among locus of control, instructional mode, and achievement for externally and internally oriented students taught by the same instructor using two different teaching methods. A definite relationship was found among the variables, and internally oriented students attained higher achievement levels where…

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)

Describes a study that investigated the effects of using different forms of computer-based feedback on high school students' learning of science material. Hypotheses tested are discussed, five feedback conditions are described, posttests are explained, and results are discussed in terms of the information processing effects of different feedback…

Describes a study designed to assess the effectiveness of 2 science simulation programs for 11- and 12-year-olds in a developing country (Guyana). Computer-assisted learning (CAL) results are compared with results from written assignments, effect size is discussed, gender differences are examined, and ability levels are considered. (14 references)…

To detemine the effectiveness of the Individualized Audio-Tutorial (IAT) method of instruction, an IAT unit in biology was implemented in ninth grade classrooms in an urban school in Israel, and student achievement was measured in relation to gender, academic background in mathematics and biology, and IQ levels. The 180 subjects were randomly…

Describes study that investigated achievement and motivation effects related to locus of control and learner control on seventh and eighth grade Hispanic students completing a computer-assisted instruction (CAI) science lesson. Use of the Intellectual Achievement Responsibility scale is discussed, and a questionnaire that assessed student…

Describes study conducted with undergraduates in India to investigate the selection of suitable learning strategies in science instruction. Highlights include six independent and seven group learning strategies; components of students' learning potential; the influence of different components of learning potential on three achievement levels; and…

Describes a study that explored the impact of using interactive video in a seventh grade earth sciences curriculum. The effectiveness of interactive video and traditional text instructional methods in different settings (computer lab versus classroom) are compared, gender differences are examined, and recommendations for future research are given.…

Describes a study conducted in elementary and secondary schools in Northern Ireland that assessed the impact of the use of laptop computers on academic achievement in mathematics, English, and science. Treatments for the experimental and control groups are described, and performance measures are explained. (seven references) (LRW)
