The purpose of this study is to better understand the pattern generalization
problems posed in the current school curricula of Korea. Twelve of most recently
published elementary school (1st to 6th grade) mathematics textbooks and twelve
Middle school (7th to 9th grade) mathematics textbooks (a total of 24 mathematic
textbooks) were selected for the analysis. First, the different types and characteristics
of pattern generalization problems based on previous research were categorized.
Within these categories, we analyzed which pattern problems were emphasized in
the school curriculum. The results indicate that ‘relating problems’ were mainly
introduced in elementary school textbooks. ‘Searching for the same relationship’
and ‘procedure problems’ increased across the grades. ‘Pattern searching problems’
decreased across the grades, while ‘result searching’ and ‘pattern extension problems’
were rarely introduced. ‘Justification problems’ were inconsistently emphasized
across the grades. With respect to the situational characteristics of the pattern
generalization problems, ‘factual pattern generalization problems’ were consistently
introduced across the grades, while ‘contextual pattern generalization problems’
and ‘symbolic pattern generalization problems’ were introduced only to a limited
extent. Regarding the various types of pattern problems, only limited types of
problems were proposed in both the elementary and middle school mathematic
textbooks. From this study, we hope to address how the pattern generalization
problems in the Korean mathematics curriculum lack pattern exercises in the
curriculum core. We also hope to provide data which could lead to the
development of a variety of pattern generalization problems in Korean
mathematics textbooks in the future.
