What is Discussion-based Epistemic Network Analysis?
ENA supports thick descriptions based on big data about learning to assess learner performance. Epistemic frames, the theory that supports ENA, understands expertise in complex domains as a network of connections among codes assigned to different elements of collaborative discourse such as knowledge, skills, values, and decision-making processes.
Online discussion is one such domain where ENA is being used, in this case, to assess learner performance and expertise through class discussions taking place on Canvas.
How did DB-ENA come about?
C-ALT was interested in working with online discussion data to unveil the network of connections among the content (codes) that students and instructors use during collaborative discourse.
What has C-ALT done with ENA?
C-ALT began examining online discussion data from a fall semester course to answer the following research question:
How can ENA be used to show the connections that students are making, in an online discussion, between the concepts that are being learned in a learning science master’s level course?
To answer that question, Quantitative Ethnography methods were utilized to analyze, code, transform, and format the data to be used on ENA. The codes that represent the content students should discuss were:
- Concept of learning (CoL)
- Retrieval practice (RP)
- Space out practice (SoP)
- Interleaving (I)
- Elaboration (E)
- Illusions of mastery (IoM)
- Effortful learning (EL)
- Beyond learning styles (BLS)
- Growth mindset (GM)
- Reflection of theory and practice (RTP)
In the examples below, we see the network of concepts from two different students:
