The definition of 'segment' from English Oxford Living Dictionaries:
1. each of the parts into which something is or may be divided.
I hope we can say "segments of the community"; "a segment of a television program", but is it okay to say "a segment of an academic daily routine"?
For instance, there's an English Language Academy, and 3pm to 6pm is its timing, which means duration of 3 hours.
Following are the 3 segments of their academic routine in that English-language academy:
Segment 1. From 3pm to 4pm, the teachers teach Grammar.
Segment 2. From 4pm to 5pm, the teachers teach the students to read English-written Books and Newspapers.
Segment 3. From 5pm to 6pm, the teachers let the students make their own Speeches.
Here, there's question in my mind that, is it appropriate to use the word 'segment' here, or there are other better alternatives to it? I suspect that 'segment' is commonly used in TV programs.
