There have been a number of series, both dramatic and comedic, in a school setting. One of the ones with the highest of aspirations was "Room 222."
The campus of Walt Whitman High School in Los Angeles was the location (just to hint at the level of reason and fairness), and the students, but mostly the faculty, is the focus as we watch these teachers and their charges both learn and instruct each other through the events and the lessons that take place.
The title location is the homeroom for Pete Dixon (Lloyd Haines), who teaches History. Two elements that made this show very unique for its time were the fact that Mr. Haines, being African American, was the de facto star of the show, and that he was having a subtle romance with another faculty member, Liz McIntyre (Denise Nicholas) which was something very rare on television in the late 1960s and early 70s.
Michael Constantine made a name for himself here as the principal, who, more often than not, really listened to his staff and didn't dictate. Karen Valentine as a teacher's aide, also became a favorite for her intelligence and care. Both of them won Emmys for their performances.
The fact that the student body of this school was so diverse was another unique element of the program, with no one making a big deal about that factor - surely something that was surprising for audiences of the day.
I think part of the reason this show hasn't been seen in reruns is that some episodes don't play very well anymore and certain episodes really don't make sense, generally - like one where the high school kids intended to do a performance night with a nude scene ending (a clear reference to Broadway's hit musical at the time, "Hair'), knowing their parents would be in attendance!
But, more often than not, "Room 222" examined issues that were important to kids at the time, and may still have some resonance for students today. And, when you look at the constant debates about learning, about what is appropriate to teach, about trying to give the next generation a good start and to help them become citizens that could uplift our society, there's no doubt that we could use a similar show with the same kinds of virtues and values as this one, now.
Of all the programs that have been considered or have received a reboot, we are overdue to get a brand new 222.
