Learning on Curriculum 2013 is expected to enrich students\\\' learning experiences through a scientific approach. One of the activities ofscientific learning approach isquestioning. Questioning activities are expected to arise from students. But the activity of asking students in biology learning is still low. Therefore,the REALQUESTING learning model is developed to improve students\\\'questioning skills.Product quality criteria for model development are validity, practicality, and effectiveness. The purpose of this research is to develop a valid, practical, and effective REAL QUESTING learning model. The research method used in this research is the research method of development of Borg and Gall. Based on the results of data analysis can be concluded that the development of REAL QUESTING learning model meets the three aspects of product quality criteriathose are the validity 88.40 (very valid), practicality 81.40 (highly implemented) and, the effectiveness of the student,s questioning skill 77.50 (good), student learning with N-Gain analysis 0.75 (high), and student response 89.14 (strongly agreed) for use in main field testing.
