Three years ago, Bill Gates delivered a ten-minute TED presentation about the lack of meaningful feedback teachers receive so they can improve their instruction. Gates believes other countries outperform the United States across every subject for K-12 education because the United States has no system for the development of entry-level teachers with high-quality models, mentors, and evidence of the effectiveness or ineffectiveness of their own practices. Gates offered a controversial solution: recording teachers across the country and evaluating their performance based upon student outcomes and the videos themselves. While Gates conceded this proposal would cost approximately $5 billion and would probably face immediate resistance from teachers and districts, he asserted the benefits of this program would significantly outweigh its costs. You can watch the entire presentation below:
The question remains: should we record our teachers, and how should we use the information collected from these videos? Gates and his supporters list several benefits of recorded lessons: these videos can help teachers recognize the relative success of their own lectures, activities, and classroom management procedures; share effective lessons and policies with their colleagues; produce databases of the best-practices of instructors nationwide; and identify teachers who deserve rewards for their work or need additional guidance and support. Nevertheless, this proposal has some potential drawbacks. First, continual video would significantly reduce the privacy of teachers and students during class. Second, if administrators used these videos for teacher evaluations, then districts would need regulations against “cherry-picking” positive or negative results for specific instructors. Finally, schools need resources so they can not only identify the limitations of their current methods but also incorporate technology, policies, and personnel whenever shortcomings are identified. Overall, I believe we should let teachers record themselves so they can improve their own instruction but feel we should approach any mandatory video system with caution.
