Direct linkLee, Minkyung; Clariana, Roy B. – Educational Technology Research and Development, 2022
This experimental investigation considers how the inherent conceptual structure of external representations influences individuals' knowledge structure, and in addition proposes a measure of global collective knowledge to account for the influence of pre-existing knowledge structure. In two studies, undergraduates in a hospitality management…

Hatsidimitris, George; Kalyuga, Slava – Educational Technology Research and Development, 2013
Learning with instructional animations may overstretch limited working memory resources due to intense processing demands associated with transient information. The authors investigated whether explicit instructional advice coupled with a task-specific learner control mechanism (such as a timeline scrollbar) could facilitate the successful…

Cromley, Jennifer G.; Azevedo, Roger – Educational Technology Research and Development, 2009
New literacies researchers have identified a core set of strategies for locating information, one of which is "reading a Web page to locate information that might be present there" (Leu et al. in: Rush, Eakle, Berger (eds) "Secondary school reading and writing: What research reveals for classroom practices," 2007, p. 46). Do middle-school, high…

Azevedo, Roger; Moos, Daniel C.; Greene, Jeffrey A.; Winters, Fielding I.; Cromley, Jennifer G. – Educational Technology Research and Development, 2008
We examined how self-regulated learning (SRL) and externally-facilitated self-regulated learning (ERL) differentially affected adolescents' learning about the circulatory system while using hypermedia. A total of 128 middle-school and high school students with little prior knowledge of the topic were randomly assigned to either the SRL or ERL…

Kopcha, Theodore J.; Sullivan, Howard – Educational Technology Research and Development, 2008
This study examined the effects of prior knowledge, learner preference for control, and type of control (learner or program) on the achievement of middle-school students in a computer-based instructional program on adding and subtracting integers. Students were blocked by preference-for-control scores and randomly assigned to either a…

Enhancing Self-Efficacy for Computer Technologies through the Use of Positive Classroom Experiences.
Peer reviewedErtmer, Peggy A.; And Others – Educational Technology Research and Development, 1994
Describes a study of undergraduates completing electronic mail and word processing tasks that investigated the effects of experience on attitudes toward computers and judgment of confidence, or self-efficacy. Use of the Computer Technologies Survey is discussed, and treatment of experimental and control groups is described. Survey instrument and…
