Discusses the process of designing a series of case-based interactive videodiscs to be used within a constructivist learning environment for elementary school science. Topics include assumptions about learners and learning; implications for learning materials; and implications for the instructional design process, including process-based versus…

Discusses the design of a series of case-based interactive videodiscs used for coaching preservice elementary science teachers to become reflective practitioners. Topics include HyperCard stacks; the formative evaluation process; and design features appropriate for materials developed in other content areas or with other technical platforms.…

This study investigated learners' preconceptions of interactive video (IV), instructional television (ITV), and television (TV), and compared three treatment groups on learners' perceptions of invested mental effort and achievement on a test of recall and inference. The three treatments consisted of an IV lesson that included practice questions…

Discussion of learners' preconceptions of media focuses on a study that investigated preservice teachers' preconceptions of the ease of achieving various learning outcomes (i.e., psychomotor, affective, verbal, and intellectual) using the media of interactive video, computers, television, and books. It also examined whether preconceptions varied…

Analysis of a survey of 42 undergraduate students rating ease of learning psychomotor skills, intellectual skills, attitudes, and verbal information from books, television, computers, and interactive video. Data analysis indicated a significant medium by domain interaction. Interviews revealed student perceptions were influenced by capabilities of…

In designing materials for use in a contructivist learning environment, instructional designers still have a role in selecting the situations that may provide a stimulus for knowledge construction and providing features that support students and teachers in using these materials. This paper describes the process of designing a series of case-based…

The purpose of this media study sought to determine whether similar patterns are found (1) when interviewing a larger number of participants and (2) when focusing on a specific content area. Thirty-eight undergraduate students enrolled in an undergraduate computer education class in a large Midwestern university volunteered to participate in…

This study examined the factors that contribute to learners' perceptions of the ease or difficulty of learning a specific task using a specific medium were studied, specifically whether the preconceptions of preservice teachers vary by learning domain (verbal, intellectual, affective, and psychomotor) or medium of presentation (interactive video,…

Describes study of undergraduates that investigated learners' preconceptions of the difficulty of interactive video, instructional television, and television. The effects of actively or covertly responding to practice questions on perceived mental effort, recall, and inferences are examined, and correlations between lesson time and inference or…
