James, Ryan Gregory – ProQuest LLC, 2013
How much information do natural systems store and process? In this work we attempt to answer this question in multiple ways. We first establish a mathematical framework where natural systems are represented by a canonical form of edge-labeled hidden fc models called e-machines. Then, utilizing this framework, a variety of measures are defined and…

Waters, John K. – Campus Technology, 2012
Colleges and universities are swimming in an ever-widening sea of data. Human beings and machines together generate about 2.5 "quintillion" (10[superscript 18]) bytes every day, according to IBM's latest estimate. The sources of all that data are dizzyingly diverse: e-mail, blogs, click streams, security cameras, weather sensors, social networks,…

Cress, Ulrike; Held, Christoph; Kimmerle, Joachim – Computers & Education, 2013
Tag clouds generated in social tagging systems can capture the collective knowledge of communities. Using as a basis spreading activation theories, information foraging theory, and the co-evolution model of cognitive and social systems, we present here a model for an "extended information scent," which proposes that both collective and individual…

Frederiksen, Christian; Kehoe, E. James; Wood, Robert – Learning and Instruction, 2011
This study tested the effects of two instructional aids in a complex, dynamic environment, specifically, a business simulation. Participants studied (1) a "causal map," which depicted key variables in an interconnected network, (2) a textual outline of the same relationships, or (3) no-aid. With the relevant aid still available, the participants…

Guan, Ying-Hua – Educational Technology & Society, 2009
This study investigated the effects of multimedia presentations on the efficiency of learning scientific information (i.e. information on basic anatomy of human brains and their functions, the definition of cognitive psychology, and the structure of human memory). Experiment 1 investigated whether the modality effect could be observed when the…
