Mixed-methods design for an objective-based evaluation of a magnet school assistance project

This article describes and discusses the development and implementation of an evaluation design to assess a magnet assistance project, which integrates a mixed-methods approach into the objective-based evaluation. By combining both quantitative and qualitative methods, this design can address some of the weaknesses of objective-based approach in the process of evaluation. Functions of mixed-methods approach, such as initiation, triangulation, complementarity and development can possibly contribute to improving program progress, avoiding information narrowness and uncovering side effects. The examination of this design also reveals that the mixed-methods approach is not only possible, but more effective, and has higher validity. The mixed-methods is a more useful and accountable approach, which can be used in integration with the traditional objective-based approach to conceive and implement evaluation, especially in program evaluations with broader audiences, longer terms, and more complex goals.
