This study sets out to analyze the problems with the old integrated curricula and subjects,
consider theme-centric integrated learning in terms of concept, model, and previous studies, and
design theme unit-centric integrated learning and integrated performance evaluation. The results
reveal that “theme unit-centric integrated learning and integrated performance evaluation” had
the potential as alternative integrated learning to overcome the problems with the current
integrated curricula and the limitations of the characteristics of the integrated subjects.
The conclusions of the study are as follows: first, “theme unit-centric integrated learning”
designed as one of approaches towards integration was not separated from the school curricula.
It\'s necessary to develop a range of in-service training programs related to theme unit-centric
integrated learning so that the teachers can make use of it in person. Secondly, “theme
unit-centric integrated performance evaluation” developed in the study was combined with the
performance evaluation carried out during the subject\'s unit hours in school instead of
separating lessons and evaluations, thus helping to run a curriculum in which the educational
goals would match the educational evaluations.
In order to implement “theme unit-centric integrated learning and integrated performance
evaluation” in a more effective way, there should be more chances for in-service training to
help the teachers increase their professionalism related to the areas, and more diverse programs
should be distributed in respect to integrated learning. Instructors need to utilize more diverse
teaching and learning methods of integrated learning by testing the effects of theme unit-centric
integrated learning and integrated performance evaluation, and further revising and
supplementing them.
