As certain studies have revealed (Ashton, 1985; Skinner and Belmont, 1993;
Lorenzo Bergillos, 1997; García Sánchez, 1999; Uribe, 1999), the classroom as
microsystem can modify the students’ motivation. DeCharms’ research (1976) is in line
with this idea. Indeed, this author varied classroom methodologies in order to manipulate
the students’ motivation, and found that they resulted in important changes in the
learners’ autonomy and self-regulation.
