Basic theory in cognitive psychology and information processing psychology of design and test of a meta - cognitive level , Organic Chemistry test , organic chemistry problem solving oral report , Organic Chemistry solve the problem of the Metacognitive level supplement test , the conceptual structure of the degree of 16 typical organic chemistry test check . The results show that : ( 1) metacognitive level , declarative knowledge on the degree of structure between poor students and excellent students there are obvious differences ; ( 2 ) the degree of declarative knowledge structure differences in performance in its the difference on the the conceptual structure nodes , the number of levels and propositional number . The level of degree of structure can be measured by the number of propositions in the conceptual structure and level of quality in the conceptual structure directly determine the number of how many of the proposition , the level of the most essential factors affect the level of quality students understanding of the concept of connotation and denotation clear ; (3 ) metacognition through coordinated attention to the allocation of resources , monitoring of cognitive activity carried it with more purpose and continuity , use of cognitive strategies and other means to influence the process of organic chemistry problem solving ; declarative knowledge structure of the level of the degree of a direct impact on organic chemistry problems to resolve operation steps in the process and overall processing speed , the object of the operation and the problem representation , the possibility of operation and quality . (4) metacognitive declarative knowledge structure of the degree of both impact solve organic chemistry problems : Metacognitive for the success of the organic chemistry problems solution provides a possible to directly determine the degree of structure and declarative knowledge Organic Chemistry problems can be successfully resolved. The paper pointed out that the high school chemistry teaching to focus on students ' metacognitive training, to focus on the students' declarative knowledge structured .
