A teacher is saying to her students:
Between now and then, observe yourself. Bring in information. Be committed, constant and fair to each other.
Does it mean "in this time period"? or it means "sometimes"?

"Between now and then" always means "in this time period". It never means "sometimes". The reason becomes apparent if you consider the dictionary meaning:
Adverb. Occasionally, rather than all of the time.
The teacher's instruction would be understood as meaning the task must be completed by the given date, i.e. by "then". However, the adverbs "sometimes" or "occasionally" don't have this time limitation: they're open-ended. "Sometimes" would include carrying out the task after the date or time specified by "then".
My bet is that if you didn't carry out the task before "then" (because you thought the teacher meant an open-ended "sometimes"), you will be in trouble with the teacher.
I think both are possible, it depends of your level of criteria, and by all means, on you levels of pragmática. I personally think that this means “sometimes”!
