Systems thinking plays a key role in producing the understanding of a big picture — a broader view of looking at the overall system needed to develop a learning community more effectively. Practical expectations to improve the functioning of Human systems, here teacher preparedness, on identifying possible interventions, relate at description and partial evaluation of how the systems work. This paper circumscribes linguistic situations and considers individual differences, reluctance for a pedagogical change and administration as interventions in a specific human learning system of importance in education during teacher training. Thereby, an Intervention Solving Protocol [ISP] was addressed to the following problem: How can we improve a learning community of students enrolled in teacher training? In what follows, intervention-solving protocol called ISP explicates the interventions to bring about a transformation to attain the desired state of linguistic education, improved communication and enhanced thinking.
