As apart of architecture theories, there are different themes, concepts, and ideas applied to design studio. I will be grateful if you suggest any references please.

There is no single answer to a question as general as this. It is advisable to disregard singular answers to questions concerning a pluralistic and fast changing field as architecture. My question is still what do you want to specifically accomplish in the studio? What are the questions asked?
It is puzzling that one should believe that there is a single answer to questions concerning cinematic architecture, narrative architecture, forensic architecture, performance-oriented architecture, artistic production oriented architecture, architecture engineering, and so on, when even each thematic take in itself frequently comprises of many and often contradictory approaches. As architecture is maturing the range of different approaches increases and more areas of specialization occur. One example of this kind is the notion of performance in architecture in which clearly rather opposing approaches exist. For this reason I like to reiterate my question regarding the thematic context of the question of theoretical concepts for studios. Without a more detailed discussion responses will tend to be formed by interpretation based on no discernible criteria and biased by personal preferences. In a scientific forum we should be able to do better.
