  • The Development of an Online Learning System for Understanding Research Design and Analysis Concepts

    Duke University SON CONCEPT Office CATALYST Award
    07/2014 to 06/2015
    Role: PI

    Project Goals: The goal of the project is to develop a non-linear interactive online system in which all concepts related to research design and analysis are displayed at once with each one representing a distinct node in a web of ideas, with the effect being similar to the look and feel of Prezi presentations. Each node will be a brief 15-minute overview with animated slides and voiceover narration describing the concept. The learner may then choose to move up to a more basic description, down to a more in-depth discussion, or sideways to learn more about related concepts and their connections to the original concept. The system will be used as an online resource for design and analysis courses and may be integrated across the ABSN, MSN (e.g. Scholarly Dimensions I and II courses) and PhD programs as a supplemental tool to enhance understanding of research concepts.
