Discusses instructional analogies and describes two studies which were designed to examine the effects of instructional analogy training on college students' ability to identify the application of advanced physiological concepts. Student performances are compared with and without analogies and future research is suggested. (Contains 71…

The purpose of this study was to determise the relative loss in statistical power of traditional methods of analysis when response-shift bias is present. Five methods of analysis (posttest scores only; postminus pretests; postminus retrospective pretest; postcovaried by pretest; postcovaried by retrospective pretest) were compared. (Author/BW)

Describes a study of high school students that investigated the impact of embedding an instructional map into hypermedia courseware on student achievement. Treatment of experimental and control groups is described, results of pretests and posttests are compared, and implications for software designers and teachers are suggested. (Contains 23…

Describes a study that measured sense of community in a television-based undergraduate distance education course and in the same course taught by the same instructor in a traditional face-to-face learning environment. Reports results of pretests and posttests, analysis of variance, analysis of covariance, and discriminant analysis. (Author/LRW)

Describes study of high school students that was conducted to determine whether instruction in a second programing language helps produce transfer of problem solving skills. The six dependent variables used in the study are discussed; pretests and posttests are described; and suggestions are made for further research. (36 references) (Author/LRW)

Describes a study that was conducted to determine whether learning to program a computer in Pascal or FORTRAN improved problem-solving skills of college students when compared to a control group and to determine which programing language was more effective in the development of problem-solving abilities. (26 references) (LRW)

Describes study that examined the relationship between computer anxiety and the use of psychology courseware in an undergraduate abnormal psychology class using four computerized case simulations. Comparisons of pretest and posttest computer anxiety measures are described, and the relationship between computer anxiety/attitudes and computer use is…

This study investigated the effect of encouragement, inspection, and training on the effectiveness of supervisors' developmental activities with their subordinates. Treatment groups were established on each variable. A specially developed questionnaire was administered, before introduction of the study variables and again six months afterward, to…

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…

Five methods for analyzing data from pretest-post-test research designs are discussed. Analysis of gain scores, with pretests as a covariate, is indicated as a superior method when the assumptions underlying covariance analysis are met. (Author/GDC)

Describes a study conducted in a Hong Kong primary school that compared the effects of learning LOGO programing with a process-oriented approach and a content-oriented approach to problem-solving skills. Transfer of training to nonprograming problem solving is discussed, and instruments used to assess students are explained. (33 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)

This study of 58 first graders used audiocassette recordings of a familiar story to examine the effects of three integrated and contiguous instructional designs using incongruity humor on recognition and recall of information as measured by immediate learning and retention tests. Research methodology is discussed, and 68 references are listed.…

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)

Discussion of the instructional effectiveness of educational software focuses on a study of undergraduates that investigated the effectiveness of a problem-solving program designed to assist students in solving nonlinear optimization problems. Results are reported that indicate manual procedures resulted in greater learning than use of the…
