This study is based on the perspective that real world tasks can facilitate students‘ integrative
capacities. To investigate the extent to which real world tasks found in the Korean mathematics
textbooks for the 7the graders integrate key competencies, a framework of mathematical
competences was developed by adopting the goal dimension of Yungbokhap education. The
analysis suggests that most of the textbooks adopt the competence to use tools interactively,
and that the frequencies of the other two types of competences, i.e., interacting in
heterogeneous groups and acting autonomously, were very low. The results of this research
showed that Korean mathematics textbooks still focus on the competence to use mathematical
knowledge, concept and principle. Only a limited number of tasks in the textbooks integrated
two or more competences. Based on the results, implications were presented for the
development of mathematics textbook tasks to promote diverse competencies.
