The next purpose is to find out the attitude of the students against the osborn learning model. Methods used in this research is quasi Experimenter Method with pretest and post-test Marginalized Control Design. Population on this research are all of &nbsp;students &nbsp;of &nbsp;VIII &nbsp;grades &nbsp;in &nbsp;SMPN &nbsp;1</em></p><p><em>Bandung. Samples on this research are two classes&nbsp; &nbsp;of&nbsp; &nbsp;VIII&nbsp; &nbsp;grades,&nbsp; &nbsp;one&nbsp; &nbsp;class&nbsp; &nbsp;as</em></p><p><em>Experimental Class and the other one as control&nbsp;&nbsp; &nbsp;class.&nbsp;&nbsp; &nbsp;Research&nbsp;&nbsp; &nbsp;data&nbsp;&nbsp; &nbsp;obtained</em></p><p><em>t</em><em>hrough the test of student’s mathematical problem solving competence, questionnaire, and &nbsp;observation &nbsp;sheets. &nbsp;The &nbsp;result &nbsp;of &nbsp;this</em></p><p><em>research shows that the increasing of student’s&nbsp; &nbsp;mathematical&nbsp; &nbsp;problem&nbsp; &nbsp;solving</em></p><p><em>competence with Osborn Learning Model better than&nbsp; &nbsp;the increasing of student’s mathematical &nbsp;problem &nbsp;solving &nbsp;competence</em></p><p><em>w</em><em>it</em><em>h conventional learning.
