Larry Ferlazzois teaches English, Social Studies and International Baccalaureate classes to English Language Learners and mainstream students at Luther Burbank High School in Sacramento, California. Recently on his blog he has been highlighting free sites and services  (many require registration) that are useful to educators as well as librarians. This week among the apps he recommends: “PPTX lets you create AI-powered PowerPoint presentations for you. It really doesn’t produce much actual info content, but the slides look nice.”
