Emphasis was shifted from <u>experiments</u> in the academic laboratory to the application of phycology to the issues of teaching and learning.
Transition took place from controlled environments to focusing the interest on real ones, each of them totally different from others and where external conditions affect human reactions, for example, the socioeconomical, cultural or familiar conditions of students in teaching and learning processes are going to affect their responses to the metodologies they are exposed to. This cannot occur in an artificially controlled environment such as a laboratory.
