Schools' missions are to optimize the allocation of available educational resources in their teaching activities. Schools' most important resources are teachers and other educators. However, the teaching methods and degree of productivity depend on students, teachers and teaching materials. Educational efforts have been relatively successful in the third stage of the learning process. Practical courses , projects, Master and Doctoral courses are good examples of educational productivity in the third stage of the learning process.
Students spend as much time as possible on home studies.
These efforts are parts of the second stage in the learning process. Teachers have been spending most of their valuable time on optimizing the use of available educational materials in the first stage of the learning process. However, the degree of productivity in schools also depends on the educational materials. Two-way communication between teachers and students assures understanding. But, teachers don't have enough time to tutor all of their students on all the new topics.
