In this chapter of the book we have described and analyzed what student-teachers understand by self-regulated learning, what they do when applying the different phases of this process and what are the difficulties, they have to regulate their learning. Student-teachers participating in the study are pre-service teachers who are trained to work in the school system as secondary school teachers. The sample consisted of 60 student-teachers from a university in southern Chile. The main findings show that students relate the concept of self-regulated learning mainly with the general organization prior to the study and with the regulation of their emotions. Regarding the process of self-regulated learning, it is suggested that the planning and execution phase are incipient because there is: (i) lack of strategic planning in the planning phase, (ii) lack of motivational self-control processes, which influences the lack of regulation as: disorganization and uncontrolled emotions, (iii) absence of self-records that allow them to compare and monitor the execution of the study. Additionally, it is proposed conceptual model includes components that represent: (i) the understanding of the concept of self-regulation of learning, (ii) development of the process of self-regulation of learning, (iii) lack of regulation and (iv) external agent’s antiregulation of learning.
