| To implement the fundamental task of "moral education",we must establish a teaching awareness oriented to cultivating students’ core literacy.The unit instructional design is an important means to implement the core literacy by using the whole unit thinking to grasp the teaching content and aim at developing students’ problem-solving ability,which is also helpful to change the current phenomenon of teaching fragmentation.In this paper,we take the sequence of number unit as an example and develop the unit instructional design in order to provide reference for teachers and develop students’ core literacy in mathematics.Three main issues are discussed:(1)The current situation of teaching the sequence of number unit in high school;(2)The general framework of unit instructional design;(3)The construction of unit instructional design using the sequence of number unit as an example.Firstly,this study combs the relevant literature and theories such as unit instructional design and high school sequence of number teaching,we clarify the general framework of unit instructional design and further analyze it with related teaching and learning theories;secondly,the questionnaire survey method and interview method are used to investigate and analyze the teaching situation of the current high-senior sequence of number unit.Combined with the above results,using case study method to take the sequence of number unit as an example for unit instructional design.The conclusions of this study mainly include the following parts:(1)current situation of sequence of number unit teaching: from the perspective of students’ learning,students understand the general content of the unit,but don’t understand the essence of the sequence of number and the basic problems of the unit,and have difficulties in solving comprehensive sequence of number problems and summation problems;from the perspective of teachers’ teaching,they have the awareness of unit instructional,but they don’t have sufficient understanding of the relevant theories of unit instructional design,and rarely introduce the basic learning ideas of the unit before teaching.(2)the overall framework of unit instructional design includes the following parts: unit instructional elements analysis,unit objective design,unit process design and unit evaluation design,where the analysis of unit instructional elements include mathematical analysis,learning situation analysis,curriculum standard analysis,textbook analysis,college entrance examination analysis and learning problem analysis,etc.;(3)take the sequence of number unit as an example,select "the concept of series","the concept of arithmetic progression","Sum of the first N terms of geometric progression","unit review" for unit instructional design,it can be used as a reference for the teaching design of sequence of number unit. |
