The background of this research is be the need of subtance study to learningprocess. The kind of subtance study has used textbook. Textbook do not yet tobring a problem at first lesson and do not yet to facility student to autodidact. Toallied has expanded subtance study at mathematical module based discoverylearning at phythagoras theorem subject. The purpose of research is to knowvalidity and practicality module based discovery learning. The kind of research isdevelopment by use of 4D’S model. 4D’S model comprise with 4 step is define,design, develop and dessiminate. The result of validity test module baseddiscovery learning by validator to present that module based disvery learning hanecriteria very valid is on the average 3, 34. Where as the result of practicality bystudent and teacher to indicate module based discovery learning at category verypractical as 88,9%. So that be able to conclusion module based discovery learningat pythagoras theorem subject is very valid and very practical.
