The Korean 7th National curriculum introduced a new curriculum system, so-called 'multi-level curriculum', which has an intention to narrow academic gaps among students by providing students differentiated curricular experiences based on their aptitude and academic abilities. Traditionally, this kind of educational practice has been called curriculum differentiation which makes different educational experience available to different groups of students. In other word, curriculum differentiation organize school systems so that students who appear to vary in their educational needs and abilities can be separately, either in different schools or in the same school in different programs, classes, or teaming groups within classrooms. These kinds of educational arrangements have been known variously as ability grouping, tracking, setting, or streaming.
The purpose of this study is to review and synthesize various results of curriculum differentiation research by meta-analysis technique. Meta-analysis as a formal quantitative methods of research reviewing typically use the effect-size statistics to describe study finding. In order to achieve research goal, this study examines several studies on effects of implementing the multi-level curriculum in Korea, and analyze some representative meta-analysis outcomes reported by lames Kulik and Chen-Lin Kulik, Robert Spavin, Gemoran and Berends, and Vaughan. Those reviews on the effects of curriculum differentiation, mainly based on student's academic achievement level just like ability grouping would be a good source of assumptions about grouping practices. Although an unitary conclusion could not be drawn from the review, several tendencies could be found.
First, students at higher aptitude benefit academically from ability grouping. The academic benefits are positive but usually small when the grouping is done as a part of a broader program for students of all abilities, for example, XYZ classes. On the other hand, academic benefits are positive and often large in special classes for the superior gifted students.
Second, based on this review, grouping programs usually have smaller effects on middle and lower aptitude learners. Academic achievement of middle and lower level students learning in groups by abilities could not be distinguished from those of similar students in heterogeneous grouping classes.
Third, the noncognitive outcomes of grouping practices is less clear. Self-esteem, motivation, and self-concept which are usually known as important constructs of affective domain have not been often studied by curricularists, and only tentative conclusions could be drawn.
