Research on Development of teaching materials in Mathematical Education -Significance to develop teaching materials Complement in Elementary Mathematics-

摘要

This study will consider the significance to develop teaching materials Complement. In addition to clarify the perspective to develop teaching materials based on the problems of the past. I have considered previous research on Number-sense and Mental-arithmetic. I was able to find 4 points of Number-senses problem ‘‘The difficulty of defining’’ ‘‘Consider the system of teaching contents’’ ‘‘Teaching associate Number-sense and calculation’’ ‘‘Validation of teaching materials the theoretical and practical’’. In addition, mental arithmetic was not appreciated enough in research and teaching case in the past. However, foresight about the teaching calculation is valid the presence of number is growing significantly now. I have found the need for develop teaching materials ‘‘Complement’’ that takes into account the lessons learned from the ‘‘Anzan-ronso’’ era. It is important that we consider 4 points ‘‘Degree of short-term memory loads’’ ‘‘Development of mathematical model for teaching Complement’’ ‘‘The teaching system of Number and Calculation’’ ‘‘Method of teaching’’.
