Development of an Instructional Design Model for Physical Chemistry based on Multiple Representatives

The purpose of this study was to develop an instructional design model for physical chemistry courses based on multiple representatives for chemistry education students in Indonesia. In this research, several types of development methods were adopted and conducted during the early stages of development. The Lee's approach was used as a methodological framework for the instructional design model of the current study. Prototype I of the instructional design model was validated by some instructional design experts. The validation result of prototype I showed that it had a robust quality with a mean score of 4.45. This shows that prototype I could be applied to physical chemistry courses in the classroom after some suggested revisions from the instructional design experts were done. After the revision, prototype II was created which improved the content and design of the prototype I in accordance with the recent curriculum, the rules, and elements of education.
