Google has been getting deeper into education, particularly into higher education. For example, their interest in creating a technically skilled, innovative and diverse workforce has moved them into computer science (CS) education.
That is a logical path for the company and they are interested in developing programs, resources, tools and community partnerships which make CS engaging and accessible for all students.
In STEM generally, women and minorities are historically underrepresented and that's true for computer science at the post-secondary level. In the U.S., women and ethnic minorities each represent just 18% of computer science graduates.professional experience.
You would expect Google to have sophisticated analytics, and analytics in online education software is a key feature in an LMS today as a way to understand how students are doing in greater detail than is possible by trying to do it manually. Course Builder offers several built-in analytics that require little set-up and also options for creating custom analytics using Google Analytics and Google BigQuery. They do note that not everything is free - running either type of custom analytics counts against your App Engine quota and can incur costs.
Course Builder is part of their overall education strategy. Check these links for more information:
