theodp writes: Sharing its latest research on unconscious bias in the classroom, Google warns that educators may unintentionally discriminate against some of their students, discouraging them from pursuing certain fields of study, like computer science and STEM. "By focusing on educators," writes Google's head of R&D for CS education, "we can help them become aware of their unconscious biases [e.g., perceiving Black students as disruptive, inattentive, and less likely to complete homework; perceiving misbehavior as worse when observing students of a race different than their own] and learn how they can adjust their actions to support diverse students in computer science and STEM." So, one wonders what those who conducted the Google research might make of Microsoft TEALS, a pet program of Microsoft CEO Satya Nadella that sends volunteer software engineers with no teaching experience from Microsoft, Google, Facebook, etc. into high schools across the nation to teach kids and their teachers computer science. "Our mission," states a TEALS booklet, is "to provide every student with the opportunity to study rigorous computer science in high school." Sounds good, but in a section entitled "Identifying Students Prepared to Succeed" in the TEALS Implementation Guides from 2014-2017, schools are advised, "Especially while the courses are new to your school, it is important to select only students who are interested in CS and able to handle the course work (including study skills, and behavioral issues). This is not a place to put students simply because they have an open period and expect that CS class is equivalent to playing games." A flyer for the 2017-18 school year boasts that "TEALS students scored 10% higher than the national average on their AP CS exams last year." Whether any of that lift may be attributable to screening out certain students will presumably be addressed by a still-underway 4-year, $1.5 million NSF study of the efficacy of TEALS "in an authentic high school learning context."
