According to TIMSS and PISA results, the math achievement of Korean students was high
but the affective achievement was at a very low level. In this study, data from the Korean
National Assessment of Educational Achievement was used to evaluate the middle school and
the high school students\' affective domain. The results are as follows.
First, the high school students\' affective achievement was lower than the middle school
students\'. High school students answered more negatively than middle school students for all
the items regarding self-confidence, interest, value, and academic self-efficacy in mathematics.
Second, while examining the factors that construct the affective domain, where interest and
self-efficacy in mathematics were high, it was discovered that self-confidence was high as well.
And, where the interest in mathematics was high, the value put on mathematics was high as
well. Third, when the variables of each affective factor were examined, the behavior control
variable was positively affecting self-confidence and academic self-efficacy in mathematics.
However, for the high school students, this was negatively affected interest in mathematics and
value put on mathematics. Using the results of this study, a special program to improve
affective achievement should be provided, such as an emphasis on appropriate subject content
and teachers\' teaching methods.
