The purpose of this study was to determine the effects of participation in Read 180, a teacher-mediated, computer-mediated reading instruction program, on the reading proficiency of 4th and 5th grade English Language Learners. The students who participated in the Read 180 program scored below the 25th percentile on the Florida Comprehensive…

In this study, we compare the first and the last sessions from an online oral proficiency course aimed at doctoral students conducted in the virtual world Second Life. The study attempts to identify how supportive moves made by the teacher encourage learners to engage with language, and what type of linguistic behaviour in the learners leads to…

Questions about the suitability of cognitively-oriented instructional approaches for students of different academic levels are frequently raised by teachers and researchers. This study examined student participation in knowledge-building discourse in two implementations of a short inquiry unit focusing on environmental problems. Participants in…

This study compares overall laboratory averages and individual test scores along with a student survey to determine the effects of using virtual microscopy in place of optical microscopes in a large undergraduate human anatomy course. T-tests revealed that the first two laboratory examinations (of four) and the overall laboratory averages were…

This study examined the comparative impact of two generations of a computer-assisted career guidance system, System of Interactive Guidance and Information (SIGI), and SIGI PLUS, on the career decidedness, vocational identity, and user perceptions of 64 college students. The students were randomly assigned to either SIGI or SIGI PLUS. The…

The purpose of this paper is to introduce, describe, and compare three individual models for designing computer assisted instruction: the Instructional System Development Model (by Alessi and Trollip); Lessonware (by Grossley and Green); and Liflander's Model (by Liflander). The comparison between these models involves criteria such as: (1) At…

This study compared the effects of several presentation sequences on lesson performance to deterimine whether sequence has a significant effect on performance in computer-based instruction, and whether using the same sequence consistently is more effective than not being consistent. Thirty-six students from the Basic Electricity and Electronics…

The purpose of this study was to investigate the results of using computer-assisted instruction to teach basic English grammar material in a senior high school English class. Two experimental groups (one male and one female) consisting of 51 students received computer-assisted instruction as part of the method of instruction, while the control…

One hundred and twenty-four high school students were randomly assigned to four groups: 33 subjects memorized the rule statement before, 29 subjects memorized the rule statement during, and 30 subjects memorized the rule statement after instruction in rule application skills. Thirty-two subjects were not required to memorize rule statements.…

Three experiments were run using the SCHOLAR CAI (computer assisted instruction) system to teach geography to high school students. The experiments compared a method of teaching derived from analysis of human tutors (Tutorial Mode) vs. a method derived from programed instruction (Block-Test Mode). In the three experiments, Block-Test Mode was…

Examines one approach to tracking discourse level "functional" features for computer-based writers' aids by comparing the grammatical base and approach to parsing embodied in an ATN parser with that of a systemic parser, which makes an analysis of discourse-level features explicit. (HTH)

Examines characteristics of 50 frequently cited authors in the field of computer applications to education (CAE). Citation analysis used in the study is discussed, a taxonomy of topics in CAE based upon the writings of these authors is developed, and a comparison is made with data from the Social Science Citation Index. (LRW)

Details factors related to the selection of microcomputer systems for computer-based instruction, including cost-effectiveness, instruction improvement and enhancement, and projected use. Descriptions of Apple, Atari, PET, Sorcerer, Terak, Texas Instruments, and TRS-80 are included along with a glossary of microcomputer related terms. (LLS)

Describes four studies, one experimental and three comparative, that were conducted with university students to assess the instructional effectiveness of separate animated computer tutorials illustrating dynamic processes in microbiology. Results indicated a significant advantage for subjects in the animated condition as opposed to a contextual…

Pathfinder is a graphic theoretic technique used to analyze proximity data. This study evaluates its validity: (1) for representing and comparing individuals' navigation through a computer-based hypermedia environment; and (2) for generating an empirically-derived path that represents a set of individual navigational paths during computer-assisted…
