The sample was determined by purposive sampling technique, which taking 2 classes: XI IPA-1 (as the experimental class-I) applied Guided Inquiry learning model and XI IPA-2 (as the experimental class-II) applied Discovery Learning model where both were practicum integrated. This study was conducted using the Quasi Experimental design with non-equivalent group pretest-postest design. Data collection was done for pre-test and post-test by using twenty items of multiple choices instruments which were valid and reliable for learning outcomes, meanwhile 7 items valid essay test for science process skill. The result show that there were differences in the average value of learning outcomes and science process skill with the value of each tstatistics> ttable namely (3,5320>2,002 ) and (2,0595 >2,002 ).
