It’s not difficult for AJ Michalka to think about the special teachers in her life while playing an educator in the new ABC comedy “Schooled.” So much of her own time in school took place while working on the Sony Studios lot, where she’s filming “The Goldbergs”‘ spinoff series. Michalka has been appearing on television shows since she was 11, including appearances on “Passions,” “Oliver Beene,” “The Guardian,” “Birds of Prey,” “General Hospital” and “Six Feet Under” while she was going to school.
