With ongoing efforts in the United States to further develop the availability of computer science education in the public schools, federal, state, and local educational agencies are increasing efforts to encourage and promote the inclusion of computer science and programming skills in the middle school curriculum (Grover, Pea, & Cooper, 2015). The goal for the Online Content Modules: Computer Science in the Middle Grades project was the development of five online content modules with a focus on computer science instruction in three public school districts in West Tennessee, and disseminated through a week-long professional development summer institute.
