“Introduction to Robotics,” “Banned Books and the Classics” and “African-American History and Music” are just some of the courses offered to high schoolers starting July 6 at the Cambridge Harvard Summer Academy.

The academy — which also has more traditional offerings, such as “Building Skills in Algebra” — is collaboration by Cambridge Public Schools and the Harvard Graduate School of education and is free for Cambridge students.

The offering are diverse, including pre-Advanced Placement, honors preparation and enrichment courses, as well as review classes for those who hope to advance their skills, said Drew Echelson, of the graduate school’s Urban Superintendents Program.

Classes run daily from 8:20 to 10:20 a.m. or 10:30 a.m. to 12:30 p.m. Students can take up to two classes, which are taught by students in the graduate school’s Teacher Education Program, accompanied by experienced mentor teachers.

“The program boasts a low teacher-student ratio,” Echelson said, allowing for customized and differentiated instruction “and an intimate environment for students looking to either accelerate into new sequences of courses or solidify skills.”

Courses end Aug. 12, with a public exhibition of students’ work the day before.
