Question

I left out the following statements. Thank you.

1) Investigation activities will be based on four components: investigation (analyzing problems from different points of view), interaction (activities and skills) and interpretation (presentation of findings in front of the partner students)
2) Students will work in heterogeneous groups to achieve a common task.


Shall I add other things?

Answer 1

Both of these are fine, although I'd add a comma after "...skills)"

They all sound good to me.
