The evaluation of students' creative thinking has not been optimal, the use of books in the Higher Plant Botany course at the Biology Education Faculty of ULM in the Poaceae family sub-material based on creative thinking is still limited, so enrichment teaching materials are needed by utilizing local potential and using aspects of thinking creative. The scientific book development model adapted Tessmer's formative evaluation which was limited to self-evaluation, expert review of 3 ULM Master of Biology Education lecturers which included material experts, linguists and media experts, one-to-one evaluation and small group evaluation which included 8 undergraduate students of Biology Education FKIP ULM who have passed the Higher Plant Botany course. The assessment given by experts to scientific books obtained valid criteria (3.59). Respondents' assessment of the practicality of the content obtained very good criteria (88.89%). Respondents' assessment of the practicality of expectations obtained very good criteria (83%). The observer's assessment on the fulfillment of expectations obtained very good criteria (82%). Assessment of the effectiveness of expectations obtained high criteria (80.80) and increased creative thinking skills at three meetings obtained moderate N-gain criteria. Scientific books are declared valid, practical and effective.
