Abstract

This research aims to develop a practicality sheet that can be used as an instrument in assessing the product being developed. The product that has been developed must be validated by experts in the field of education. After the product is said to be valid, the product is tested in the field on students, where the product is said to be practical if Experts state that in theory the product can be applied in the field and has a good level of workability. Therefore, the aim of this research is to develop a practicality sheet according to an instrument that is valid and validated by expert validators in the field of education. The practicality sheet development procedure is based on the PLOMP model research and development. This research takes place at the development stage. This practicality sheet consists of a grid and assessment rubric. The grid contains aspects and indicators. The assessment rubric contains indicators and assessment score criteria, apart from that it also contains provisions for scoring the questionnaire. The practicality sheet consists of 5 aspects, namely 1) Appearance aspect, 2) Linguistic aspect, 3) Material aspect, 4) Aspec readability, 5) Presentation aspect. The practicality sheet developed has been validated by validators in the field of education and the overall practicality sheet assessment received a percentage of 96.6% with a very valid validity category. This shows that the practicality sheet developed can be used as an instrument to assess a product developed in educational development research.
