This study aims to design, design and develop a learning intervention. The product developed is LKPD based on learning models guided inquiry to improve the critical thinking skills of students of SMAN 1 IX Koto Sungai Lasi that are valid, practical, and effective. The instrument used was a validity questionnaire and a practicality questionnaire as well as a matter of effectiveness. The validity and practicality data analysis technique uses a Likert scale scoring and the effectiveness uses a t-test using SPSS 2.2. Based on the development and trial of LKPD based on learning models Guided Inquiry on the material of plant cells and tissues to improve the thinking skills of class XI students of SMAN 1 IX Koto Sungai Lasi, it was concluded that the results of the validity and practicality tests met the very valid criteria. The results of the effectiveness test have effective criteria.
