2.2 Theoretical Bases

2.2.1 Optimization of Teaching Process Theory

Optimization of teaching process‖ put forward by Soviet educator Babanski means that teachers should choose the best scheme to organize the teaching process purposefully, which can ensure that the solution of teaching and educational tasks can achieve the best effect  within  the  specified  time  (Gu  Mingyuan  &  Meng  Fanhua,  2001). ―Optimal‖ is a relative  and  conditional  concept,  and  different  conditions  lead  to  different  optimal standards,  which  requires  teachers  to  arrange  teaching  contents  according  to  students’ actual  learning  ability,  and  to  understand  the  characteristics  of  various  educational viewpoints and methods  as  well  as their appropriate application scope, so as to use them reasonably  and  selectively.  Moreover,  the  following  teaching  principles  put  forward  by Babanski are of guiding significance to the forms and purpose effect in Covertly Stratified Teaching (Yang Weiguo, 2013): 

Firstly,  the principle of teaching acceptability  reveals  that teaching materials should make  students  feel  challenging  to  their  maximum  extent  possible.  The  effective development  of  teachers’  teaching  process,  the  prominence  of  teaching  emphasis,  the adoption of different teaching methods to help students, and so on, which coincides with the fact that Covertly Stratified Teaching requires multi-level teaching methods in different teaching links. 

The principle of optimal combination  in various teaching organizations requires the optimal  combination  of  the  whole  class,  group  work  and  individual  forms  in  teaching organization.  The  whole-class  activities  can  promote  the  formation  of  collective consciousness and the atmosphere of mutual assistance; group learning activities meet the needs  of  students  with  different  learning  basics  to  a  large  extent;  individual  forms  of activities require teachers to help students use their maximum ability to complete learning tasks independently. Therefore, it is particularly necessary to realize the Covertly Stratified Teaching with the optimal combination of the three forms of teaching organization.
