C77 - Redox on YouTube: Representations, Content Features, and Chemistry Learning Potential
Mentor: Ellen Yezierski, Ph.D.
Video sharing sites including YouTube used by 90% of 18-24 year olds.(1) Educational YouTube videos sought by 75% of BIO and CHM courses with 72% believing videos are academically professional and accurate.(2) Frequency of YouTube use and Richard Mayer’s Multimedia Learning Principles3 informed prior work in the YRG (4,5) on bonding, intermolecular forces, and acid-base chemistry, building methodological knowledge to evaluate the quality of YouTube videos across multiple topics.
For oxidation-reduction, other work in the YRG surfaced limitations on traditions of instruction because of over reliance on the symbolic level6 (a la Johnstone’s representational domains7). Dominant treatment of redox symbolically has left little opportunity for the development of representational competence.(8) Research on common redox misconceptions9,10 shows promise for criteria for evaluating the quality of chemistry content knowledge (and potential to support learning) for redox YouTube videos.
