Correlation design is similar to broad-field design in that it is focused on integration. The difference is that correlation design combines only two subjects while broad-field will combine several subjects.  In many ways, one could say that correlation design is a simplistic version of broad-field design.

Some examples of correlation design include biochemistry, which is the combining of biology and chemistry. Other examples include social psychology, which is sociology and psychology; bio-statistics, which is biology and statistics; and music technology, which focuses on music and its use through technology.  Generally, correlation design is found at the university level where students need expertise in specific subjects.

The advantages of correlation design are that it fills in the gaps within curriculum of two subjects that are related. The two subjects are combined in innovative ways and the students are able to see the connections between the two of them.

The disadvantages are that few teachers have enough expertise in the two subjects to successful correlate them in a curriculum. In addition, few teachers have the time to collaborate with their peers on a project such as this.  Despite these issues, correlation design is an option for teachers interested in creating a unique curriculum for the needs of their students.
