This study aims to analyze the sequences of 'pattern and function' ranging from Math 1-GA/NA to Math 9-GA/NA based on the 7th education course.
Following issues are looked at in order to see whether textbook contents about 'pattern and function' based on the 7th education course are appropriately related.
First, are the education contents for elementary school students (ranging from Math 1-GA/NA to Math 6-/GANA) sequenced?
Second, are the education contents for middle school students (ranging from Math 7-GA/NA to Math 9-GA/NA) sequenced?
Third, are the education contents for elementary and middle school students (ranging from Math 1-GA/NA to Math 9-GA/NA) sequenced?
To carry out the research, the Doosan Corporation textbook was arbitrarily chosen out of primary school textbooks which are currently in use and 13 kinds of middle school textbooks. Based on the judgment criteria and basis of preceding researchers, was phases of the sequences identified of 'pattern and function' as 'repeat', 'development' and 'gap'.
Three results were produced.
First, given the fact that the process of finding rules and corresponding rules are visualized, tabulated and further expressed in relevant equation, the connection phase is 'repeat and development'. This process was dealt in consecutive order, showing interrelation.
Second, the phase is 'advanced development'. It seems that there are few repeated, abruptly progressed or omitted parts in middle school textbooks. With the help of the previous part and full explanation, it is likely to understand the contents.
Third, when finishing the elementary course and moving onto the middle school curriculum, many students at the level of Math 7-GA (freshmen of middle schools) take unfamiliar terms including direct proportion ratio, inverse proportion ratio, function and ordered pair as a totally new chapter
