... the form of scale of textbook quality assessment using Likert scale made in the form of checlist. The subjects of textbook quality assessment are three material experts and three media experts. Textbook quality data obtained in the form of quantitative data is converted by product quality percentage scale. The result of this research are: (1) Developed instructional product in the form of textbook based on constructivistic approach as learning material of physics education evaluation in accordance with KKNI curriculum, and (2) The quality of textbook developed has excellent quality (SB) based on assessment of material experts with a percentage of 84.05% of ideal high score 148, and excellent quality (SB) based on media expert's judgment with a percentage of 82.56% of the ideal high score of 80.Keywords: textbooks, physical education evaluations, constructivistically
