Creative instruction across the curriculum is a critical pillar of the Creative Learning Initiative (CLI). This report, the second in a series of three on CLI, shares teacher's reactions to training in Creative Teaching, how and why they use it in the classroom, and how that usage relates to student outcomes. A separate research brief also was published. [For the research brief, see ED629578. For the first report of the series, "2017-2018 Creative Learning Initiative: Creative Campus Distribution. Publication 17.55," see ED629574.]
