<![CDATA[This research is aimed to: 1) Developing module based on ARIAS learning model to improve students’ learning motivation and critical thinking in ecosystem matter; 2) Find out whether or not the use of module based on ARIAS learning model is appropriate to improve students’ learning motivation and critical thinking in ecosystem matter; 3) Find out the effectiveness of module based on ARIAS learning model usage towards students’ learning motivation and critical thinking in ecosystem matter. This study belongs to Research and Development referring to Borg dan Gall. Scheme of the module was developed into Module Draft 1. Module Draft I was validated by experts and practitioner based on content appropriateness, language, presentation, graph, base of ARIAS learning model, students’ learning motivation and critical thinking. The module was then tried out in small sample of 10 students in SMA N Kebakkramat. After revising the module based on suggestions from small scale test, the researcher revised the module into Draft II. The researcher used Module Draft II in real test on 36 students of class X-8 in SMA N Kebakkramat. The effectiveness of module towards students’ learning achievement, motivation and critical thinking was analyzed using gain score that was normalized for pre-test and post-test in the real test class. The module was then revised again into final product and was distributed to be widely developed. Results of the research are: 1) Module based on ARIAS learning model to improve students’ learning motivation and critical thinking in ecosystem matter is developed in Research and Development refering to Borg dan Gall; 2) Quality of module based on ARIAS learning model to improve students’ learning motivation and critical thinking in ecosystem matter belongs to Excellent Category in content appropriateness, language, presentation, graph and syntax of ARIAS learning model, it also shows Good Category in motivation and critical thinking appropriateness based on experts and practitioners; 3) Module based on ARIAS learning model to improve students’ learning motivation and critical thinking in ecosystem matter is effective in improving students’ learning motivation having N-gain score for 0.51 and is effective to improve students’ critical thinking having N-gain score for 0.60 in Medium Category.
