Google’s mistake: CS teacher PD must be on-line only

Google CS4HS program has had a big impact in computer science education in the United States.  According to the UChicago studies, a sizable percentage of all CS teacher professional development (PD) in the United States — 25% of all PD workshops were funded just by Google.

Google has changed the criteria for the 2014 offerings.  They will only fund all online courses.  Not so in Europe, where they are still funding face-to-face workshops.

This is a mistake for two reasons:

  1. We don’t know yet how to construct on-line CS teacher professional development that succeeds.  The drop-out rate for MOOCs is enormous, and teachers fall into the groups who most often do not complete, especially a CS-oriented MOOC.
  2. What we know about CS teacher PD says that you need to develop a community of practice, and you need to start it face-to-face.  CS is in a different place than most teacher PD.  Most teachers develop their sense of identity (which influences what professional groups they join, where they look for professional development, who they talk to about their classes) from their teacher certification: math teacher, reading teacher, science teacher.  Most states have no teacher certification for CS.  Lijun Ni’s work found that a community of practice was critical for establishing that sense of CS teacher identity.  How do you form it?  Many years ago, I got the chance to chat with Starr Roxanne Hiltz who did some of the earliest work with online teacher communities.  She said that it never worked when starting all online.  The teachers had to meet one another and establish rapport, and then the online component could take off.

Google can scale-up who gets “touched” by CS teacher PD, but will lose considerably in effectiveness.  I predict that the end result will be far fewer new CS teachers from the 2014 workshops than from previous incarnations of CS4HS.  I understand that Google is a company and has to control costs.  But the return on investment for this change will be drastically less — they will end up with fewer well-prepared CS teachers for their investment, not more.

Applicants must satisfy the following criteria in order to be eligible:

  • You must be affiliated with a college, university, technical college, community college, or an official non-profit organization
  • Your workshop must have a clear computer science focus
  • You must use Google products for content delivery
  • You must not cap enrollment

Please note:

In the US/Canada region for 2014, we will only be funding online courses (MOOCs) professional development programs
