<P> The series mainly focused on an American history class in Room 222 of the fictional Walt Whitman High School, an extremely racially diverse school in Los Angeles, California, although it also depicted other events at and outside the school, such as the home lives of students and faculty . The class is taught by Pete Dixon (Lloyd Haynes), an idealistic African - American school teacher . Other characters featured in the show were the school's compassionate guidance counselor, Liz McIntyre (Denise Nicholas), who is also Pete's girlfriend; the dryly humorous school principal, Seymour Kaufman (Michael Constantine); and the petite and enthusiastic Alice Johnson (Karen Valentine), a student teacher (and later full - time teacher) learning from Pete . Patsy Garrett played Mr. Kaufman's secretary, Miss Hogarth . In addition, many recurring students were featured from episode to episode . </P> <P> Pete Dixon delivers gentle lessons in tolerance and understanding to his students . They admire his wisdom, insight, and easygoing manner . The themes of the episodes were sometimes topical, reflecting the contemporary political climate of the late 1960s and early to mid-1970s, such as the Vietnam War, women's rights, race relations, and Watergate . However, most plots were timeless and featured themes still common to modern - day teenagers . For example, the 1969 episode "Funny Boy" deals with a class clown who is self - conscious about being overweight, the 1971 episode "What Is a Man?" deals with a student who is the victim of anti-gay harassment and the 1974 episode "I Didn't Raise My Girl to Be a Soldier" with parent--teenager issues . </P> <Ul> <Li> Lloyd Haynes as Mr. Pete Dixon, the protagonist, an African - American who teaches 11th grade American History in room 222 of Walt Whitman High School </Li> <Li> Denise Nicholas as Miss Liz McIntyre, the African - American guidance counselor at Whitman, dating Pete </Li> <Li> Michael Constantine as Mr. Seymour Kaufman, the White principal of Whitman, preoccupied with his duties but dryly humorous </Li> <Li> Karen Valentine as Miss Alice Johnson, a White student teacher learning from Pete </Li> </Ul> <Li> Lloyd Haynes as Mr. Pete Dixon, the protagonist, an African - American who teaches 11th grade American History in room 222 of Walt Whitman High School </Li>
