WHAT'S AN AVOCADO? In an op-ed on Huffington Post, Sabina Bharwani, director of educational technology at Teach for America, argues that content providers could do a better job at "culturally responsive teaching" so as "to acknowledge the need for reflecting end consumers in the makeup of any company." With all the attention on the lack of diversity in the tech industry, Bharwani says entrepreneurs can no longer be "culturally neutral to the needs and aspirations of culturally diverse learners." Teachers often make culture-specific requests to companies, and those that have responded--she cites BrainPOP and Qlovi--have been able to grow their user base. Hey, Sal: Not everyone knows about the joys of avocados!
