This paper employs meta-analysis to determine the influence of computer-based scaffolding characteristics and study and test score quality on cognitive outcomes in science, technology, engineering, and mathematics education at the secondary, college, graduate, and adult levels. Results indicate that (a) computer-based scaffolding positively influences learning (g = 0.53), (b) studies with zero ...

Individuals with cognitive disabilities are often unable to live independently due to inability to perform daily tasks. Computationally enhanced dynamic prompting systems can mitigate this. High levels of assistive technology abandonment are driven by poor user interfaces. MAPS provides an effective prompting system with an intuitive interface for

Cognitive technology is leaving the lab and entering the world of the everyday. Systems such as knowledge navigators, conversational agents, and intelligent personal assistants are increasingly incorporated into real-world systems. This success of cognitive technologies poses novel methodological challenges for interdisciplinary teams tasked with their development. In order to behave successful...

A key challenge in the design of tutorial dialogue systems is identifying tutorial strategies that can effectively balance the tradeoffs between cognitive and affective student outcomes. This balance is problematic because the precise nature of the interdependence between cognitive and affective strategies is not well understood. Furthermore, previous studies suggest that some cognitive and mot...

Instruction often employs visual representations to support deep understanding. However, students‟ prior misconceptions may override the meaning in these scaffolds. We investigate fraction bars, a common representation intended to promote sense-making. Our prior work found that students often did not use the fraction bars effectively. This difficulty factors assessment compares four scaffold ty...

The support for the use of computers in teaching and learning is widespread. Some educationalist say that the most powerful use of computing technology is as a tool for cognitive amplification or to enable students to explore mathematical concepts, and through this exploration construct mathematical understandings. Others note that the increasing power of computers enables them to exhibit artif...

The American Sign Language Sentence Reproduction Test (ASL-SRT) requires the precise reproduction of a series of ASL sentences increasing in complexity and length. Error analyses of such tasks provides insight into working memory and scaffolding processes. Data was collected from three groups expected to differ in fluency: deaf children, deaf adults and hearing adults, all users of ASL. Quantit...
