It is my understanding that the idea of a "flipped classroom" emerged when considering ways in which to level the playing field. Teachers considered that:
- some students did not do their homework,
- some did their homework or claimed to but did not turn it in,
- some students did not turn their homework in on time,
- some students had siblings or parents to ask questions of at home when doing their homework.
Therefore, to level the playing field, students would do their homework in class, under the teachers' watchful eye. Students would read the lesson material and/or watch the lesson videos at home.
Here is a link to an old thread, circa 2013, hat tip to Bostonian:
