This study compares two initiatives for preparing science teachers for careers in high-need schools, each using a distinct, locally adaptive approach. One university adopted an immersive, naturalistic strategy, with modified field placements that gave preservice teachers protracted experiences in high need classrooms. The other university provided…

The effects of conventional classroom instruction, television instruction alone, and the combination of classroom and television instruction on the learning of science content and vocabulary by 470 sixth-grade students was tested. The three treatment groups were pre- and posttested to determine the degree of achievement each group attained. The…

In a third study of the Computer Aided Learning (CAL) system of the London Borough of Havering, England, the performance of students taught biology by a teacher using the CAL system was compared with that of students taught by the same teacher without the CAL system. Students were divided into two matched groups and compared using a…

The purpose of this study was to develop, implement, and evaluate an audiotape and accompanying handouts on hemodynamics as a supplemental teaching aid in the Health Science Learning Center of New York City Technical College. It was hypothesized that there would be a significant difference between the mean examination grade on hemodynamics of…

Computer tutorial review lessons for a one-quarter lecture course in introductory college physics have been developed and used by approximately 500 students, on a voluntary basis, over a period of several years. The investigation reported here shows that the exam grades of students who used the computer materials are significantly higher (.01…

Describes a case study of secondary schools in Ibadan (Nigeria) that was conducted to determine whether programed instruction was more effective than traditional classroom methods in teaching chemistry. Treatment of control and experimental groups is described, gender differences are examined, and implications for educational practice and further…

There is substantial evidence that prose-relevant pictures contribute to increased recall of prose materials, particularly if the subjects are young children. The purpose of this study was to investigate the contribution of prose-relevant pictures to immediate and delayed recall of written prose including science content when the subjects were…

This report profiles the development, implementation, and evaluation of an interactive videodisc-based (IVD) program, Physical Sciences: Discovery through Interactive Technology. Developed by the Texas Learning Technology Group (TLTG), the program is a comprehensive, 160-hour, two-semester curriculum for secondary school students that integrates…

Describes a study focusing on different presentation methods (pairs of students; entire class; and noncomputer list game-type setting) of a computer-based science simulation to sixth-grade students to determine the most beneficial method for student achievement. Results indicate large group instruction is slightly more beneficial. (MBR)

Research was undertaken to investigate various methods of presentation of a computer based science simulation as it related to student content knowledge of the simulation concepts. Three treatment groups of sixth grade students were used in the study: (1) two students per computer interacting with the simulation; (2) a total class presentation of…

A study of eighth grade science students compared the instructional effectiveness and the cost effectiveness of an interactive video system with the use of 16mm films for teaching a science unit. Results indicated that interactive video can be significantly more effective than conventional methods of instruction. (eight references) (LRW)

These four case studies examine the introduction of interactive videodisc technology into three classroom settings by two art and two science teachers at the elementary school level. Five models of videodisc use were employed: (1) teacher presentation or teacher-led class discussion; (2) activity stimulus; (3) programmed disc-based environments…

This study investigated and compared the level of initial and long-term retention of frog internal anatomy among students using an interactive CD tutorial, a desktop microworld, and conventional frog dissection. Students' anxiety toward science was also compared across the three treatment groups and between genders. Additional data on students'…

The purpose of this study was to investigate the effects of learning strategy and summarization within a computer-based chemistry and physics program. High school students worked individually or in cooperative dyads to complete science instruction; half of them completed summaries over the instructional content when directed to do so. The study…

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.…
