Knowledge Building: Idea-Centered Drawing and Writing to Advance Community Knowledge
Peer reviewed Peer reviewed
Direct linkDirect link
Gan, YongCheng; Hong, Huang-Yao; Chen, Bodong; Scardamalia, Marlene – Educational Technology Research and Development, 2021
This study explores the dynamic, interactive nature of digital drawings and writing in a knowledge building community in which students used a multimedia online environment--Knowledge Forum--to represent and advance ideas in the field of optics. The research employs a mixed-methods case study to collect and analyze multimedia notes created by 22…

"Starburst": A New Graphical Interface to Support Purposeful Attention to Others' Posts in Online Discussions
Peer reviewed Peer reviewed
Direct linkDirect link
Marbouti, Farshid; Wise, Alyssa Friend – Educational Technology Research and Development, 2016
Online discussions offer exciting potential for educational dialogue, but too often result in disjointed conversations with low levels of interactivity. One contributing cause is the traditional text-based interface, which presents posts in a long list, leaving students overwhelmed and without useful navigational cues. To address this problem, we…

Computer-Generated Geometry Instruction: A Preliminary Study
Peer reviewed Peer reviewed
Direct linkDirect link
Kang, Helen W.; Zentall, Sydney S. – Educational Technology Research and Development, 2011
This study hypothesized that increased intensity of graphic information, presented in computer-generated instruction, could be differentially beneficial for students with hyperactivity and inattention by improving their ability to sustain attention and hold information in-mind. To this purpose, 18 2nd-4th grade students, recruited from general…

Patterns of Understanding with Open-Ended Learning Environments: A Qualitative Study.
Peer reviewed Peer reviewed
Land, Susan M.; Hannafin, Michael J. – Educational Technology Research and Development, 1997
A study of four seventh-graders using an open-ended learning environment (OELE) on mechanical physics combining computer-generated graphics, computer simulations, video, and print-based materials indicated that while learners built and formalized scientific theories, in some cases, they assimilated new data into existing theories, ignored…

Animation as Feedback in a Computer-Based Simulation: Representation Matters.
Peer reviewed Peer reviewed
Rieber, Lloyd P. – Educational Technology Research and Development, 1996
Explores how users interact and learn during computer-based simulations given graphical and textual forms of feedback. Graduate students were randomly assigned computer simulations with graphical feedback, textual feedback, or graphical plus textual feedback. Findings indicate that graphical feedback provides experiential learning, but that these…

Visual Displays and Contextual Presentations in Computer-Based Instruction.
Peer reviewed Peer reviewed
Park, Ok-choon – Educational Technology Research and Development, 1998
Investigates the effects of two instructional strategies, visual display (animation, and static graphics with and without motion cues) and contextual presentation, in the acquisition of electronic troubleshooting skills using computer-based instruction. Study concludes that use of visual displays and contextual presentation be based on the…
