Instructional Design Of Space Vectors In High School Mathematics

In order to meet the need which the new curriculum reforms, high school mathematics has introduced the space vectors.The vector is a content which the new teaching material increases, its introduction conforms to the social development need, also is advantageous to study other discipline.The vectors knows how things stand with the shape dual characteristics, is solving physical problems and other questions and so on mechanics, electromagnetics tool. In high school mathemstics introduces the space vectors, solving part of the three-dimensional geometry problems with it, may reduce the difficulty greatly and stimulates student's study interest.It is advantageous for the student experiencing the successful feeling in the study.What should our teacher pay attention to in teaching of space vectors? How designs the teaching of this part then student easy to accept?This Article from discussion space vectors introducing in high school mathematics necessary obtaining, launches take the instructional design theory as the foundation.In order to improve the quality of teaching, we have the necessity to perform the instructional design to this part of knowledge.The instructional design is the establishment in the system theory, the dissemination theory, the study theory and in a teaching theory foundation discipline.The instructional design must consider 4 basic essential factors: Teaching object, teaching goal, teaching strategy, teaching appraisal. In order to displays the teaching process well the integrated function, the instructional design must aim at above 4 basic essential factors to complete following some links the work: In view of the teaching object, carries on the analysis of the study needs,study content and student's aspect and so on characteristic; In view of the teaching goal, carries on the teaching goal design, in view of the teaching strategy, carries on the teaching strategy the design, the teaching media design, the teaching process design; In view of the teaching appraisal, carries on the teaching effect the appraisal and so on. The author utilizes this theory to carry on the instructional design to the space vectors, has given the space vectors included angle teaching design case.In this part of teaching, the teacher must strengthen intuitive, raise and enhances student's perception, trains student's mathematics thought, raises student's mathematics ability, the emphasis understanding memory.This article has given a preliminary design plan, will wait for further consummates in the next teaching practice.
