Design-Based research process: Problems, phases, and applicationsICLS 2014

Matthew W. Easterday, Daniel Rees Lewis, Elizabeth M. Gerber

Since the first descriptions of design-based research (DBR), there have been continued calls to better define DBR and increase its rigor. Here we address four uncertainties about DBR: (a) the phases of the DBR process, (b) what distinguishes DBR from other forms of research, (c) what distinguishes DBR from design, and (d) the characteristics of DBR that make it effective for answering certain types of questions. By better articulating the process of DBR, this definition helps us to better craft, improve, communicate, and teach design-based research.

Will Google destroy western democracy? Bias in policy problem solvingAIED 2009

Easterday, M. W., Aleven, V., Scheines, R., & Carver, S. M.

Confirmation bias in analyzing policy evidence may not arise because of biased search or biased evaluation, but because changes in beliefs after reading contradictory evidence have a very small effect on overall beliefs and because people recall the mass of evidence as supporting their current beliefs. This suggests that a better way to alievate confirmation bias might be to provide external representations of evidence.


Policy Teaching Through Reward Function Learning EC 2009

We explore how designers use techniques from theatrical improvisation to adhere to the rules of brainstorming thereby enhancing group interactions while collaborating. The usefulness of improvisation for brainstorming stems from the similarity of the goals of improvisation and brainstorming, the similarity of the recurrent problems that actors and designers encounter when collaborating, and the distinctness of the ways each have devised to resolve the problems that block the group’s performance.
