Development of Biology Module Based on Critical Thinking Skills on Even Semester Class X Plante Materials

The purpose of this study is: to see the characteristics, feasibility, and practicality of the development of biology modules based on critical thinking skills grade x Plantae material. Modules developed based on the 4-D development model proposed by Thiagarajan are define, design, develop, and disseminate. The product validation was carried out by four validation professors and three biology teachers at SMA Negeri 4 Palembang as practitioners. Limited trials conducted by 15 students in grade x. Data analysis techniques using qualitative descriptive analysis using formulas from Aiken’s V and azwar formulas in excel. The results of the study are as follows: (1) the characteristics of the modules developed are printed using A4 paper. The module consists of a cover, title page, identity page, preface, table of contents, list of pictures, list of tables, instructions for using the module, indicators of critical thinking skills, matter of activities, Plantae material, exercises, summaries, self-reflection, bibliography, glossary , and answer guidelines; (2) biology module based on critical thinking skills on even semester grade X Plantae material is said to be very feasible in terms of the validation results; and (3) the results of practical responses by students when in the field are stated with very practical criteria. Keywords: biology module, critical thinking skills, Plantae
