The lack of media in teaching grammar to university students and the problems faced by students in learning grammar motivates the researcher to do research and development in developing the media. The media which is concerned with peripheral verb phrases (participial phrases, gerund phrases, and infinitive phrases) are designed by considering the importance of keeping both form (structures of peripheral verb phrases) and content (the context in the sentences). In this case, the researcher usesacounterbalanced approach as the base to develop the media into counterbalanced based multimedia on peripheral verb phrases. The aim of this study focuses on the way to design counterbalanced based multimedia (simulation, drill, and evaluation) on peripheral verb phrases in teaching grammar validly, practically, and effectively. By adapting the Borg and Gall model of development, the researcher analyzed the concepts of related theories and needs to create the media based on the counterbalanced approach. Expert appraisals are needed to validate the media. In developing it, the researcher tested the media in two sessions of field tests. They covered preliminary field test and main field test. The investigation of both tests showed that the media are valid, practical, and effective to use in teaching grammar. In the last step the researcher disseminated the products to the grammar lecturers to use the media in their teaching. However, a further level of discussion of grammar topics is required to further develop a greater variety of teaching materials. To sum up, the researcher demonstrated that counterbalanced based multimedia can be validly, practically, and effectively designed to teach grammar.
