Creativity is essential for everyone; it will be one of their valuable assets that will become beneficial their organization. This study aims to develop a series of workshop classes to promote learners' creativity based on the C-K theory. This research method uses pretest-posttest control group design. The research is divided into three stages: stage 1--gathering preliminary data by exploring opinions of experts regarding developing creativity; stage 2--developing lesson plans by creating lesson plans from the analysis of the data from stage 1, then validating them by experts and piloting them; and stage 3--examining the results of implementing the lesson plans by analyzing data using repeated measures and multi-level analysis. The findings reveal that the lesson plans aim to develop creativity in learners through designing projects, or other type of work, activities based on C-K theory together with a five-class course called Design and Visualization for Film starting from (1) photo design; (2) identifying and formulating problems; (3) Reviewing problems; (4) creating a photo design based on C-K theory; and (5) designing a film poster based on C-K theory. The findings of the implementation show that the learner group who was taught by using C-K theory presented higher degree of creativity development than those who were not.
