This research aims to achieve the following: build a proposed educational unit based on Flipped Learning to acquire basic knowledge and skills of garment finishing techniques. In addition, measuring the effectiveness of the proposed educational unit in providing the trainees with basic knowledge and skills, as well as measuring the attitude of trainees towards the proposed educational unit that based on Flipped Learning. Moreover, the research aims to provide a suggested learning environment (flipped classroom environment) as one of the rotating learning models which considered a type of the flipped learning strategy. The research used the descriptive and experimental method due to its relevance to achieving goals and verifying its hypotheses.
