| In recent years,mathematical core literacy has become a hot topic in the field of mathematics education.Mathematical abstraction,as the primary position of the six core literacy,is of great significance to students' lifelong development.It is of certain significance to enrich the theory and practice of cultivating students' mathematical abstraction by studying classroom teaching.Based on this starting point,an evaluation model of abstract literacy is constructed under Marzano 's new taxonomy.In order to better guide the teaching design and give full play to the role of classroom teaching in cultivating students' Abstract thinking.Based on this,this paper sorted out the mathematical abstraction and the introduction and related knowledge of Marzano's new taxonomy at home and abroad by literature research method.After having a preliminary understanding,the connotation of mathematical literacy and its level division were studied in depth,and the specific content of Marzano's new taxonomy was discussed.It included the explanation of mathematical abstraction literacy in the new curriculum standard and the idea of the level division of related literacy on this basis.Secondly,while introducing the three systems and knowledge domains of Marzano's new taxonomy,the paper compares the similarities between mathematical abstraction literacy and Marzano's new taxonomy,and establishes a two-dimensional framework by separating knowledge from cognition,which coincides with the idea of "knowledge-based" evaluation framework,on this basis,the evaluation model is constructed.Finally,the evaluation framework is applied to the high school mathematics classroom teaching.The content of the evaluation framework is "The Concept of Function".The practical application is divided into three parts.One is the classroom record,the other is to improve the teaching design and teaching according to the evaluation framework.The third is to investigate and analyze the learning situation of the two classes before and after teaching,and draw conclusions and suggestions.The research shows that Marzano's new taxonomy fully respects the students' psychology and development,and is a complete and operable educational theory system.Under this evaluation model,the improvement of the performance of the experimental class after the teaching of the improved instructional design is significantly greater than that of the control class,and it can also play a more important role in cultivating students' Abstract thinking. |
