Focus On The Evaluation Design Research In The Field Of Computer Hardware Systems For The Cultivation Of Computational Thinking

As an important core quality of information technology curriculum,the evaluation of computational thinking has attracted much attention.Through the baptism of the last round of basic education reform,the concept of developmental evaluation,long after the learning of coarse-grained computing thinking evaluation has do not conform to the requirements of the age,stage and compulsory education and high school information technology curriculum are calculated explicitly put forward thought of evaluation should combine the specific knowledge,the higher the accuracy of the evaluation scheme of the greater the supporting function of cultivation,the landing of computational thinking.Therefore,this study chooses the specific field of "computer hardware system" and tries to explore how to design an evaluation scheme oriented to computational thinking.First of all,through literature analysis and content analysis for evaluation of both the computational thinking way after finishing analysis,found that there are both evaluation for computing thinking "in terms of evaluation of thinking",which caused the separation of knowledge and thinking,under this situation,this study found "knowledge and thinking has intrinsic consistency" of macroeconomic theory support,Build a bridge connecting knowledge and thinking evaluation.Secondly,under the macro theoretical guidance,combined with a descriptive framework and CC2001 computing thinking,core knowledge in the field of computer hardware system design frame,core knowledge frame in "computing strategy" and "concept",two dimensions in the field of computing strategy including partition,plan as a whole,compromise,encapsulation and greedy five,The concepts of computing include information system,serial process and control,parallel process and control,design,management,efficiency and security.Skeleton,and then based on the core knowledge to the field of computer hardware system for computing thinking design scheme evaluation,and evaluation scheme in the form of "analysis" and "content" two dimensions,form analysis according to different knowledge type and different ways of testing types specific evaluation analysis,and the content selection based on core knowledge framework,In this way,the evaluation program achieves the unity of form and content,space and time.Finally,the specific application of the evaluation design scheme is given,and the test questions in the field of computer hardware system oriented to computational thinking are selected for the high school section,and the scientific and reasonable test questions are verified by Delphi method.Finally,the test questions in the high school section are compiled as a research paradigm for reference.
