Validity and Practicality of Integrated Guided Inquiry (IGI) Learning Model for Senior High School Students

IGI learning model has been produced valid, and practical. The model contains rational, supporting theories, model characteristics, model instruction manuals and learning tools of the IGI model. The 4-D design instructional model was chosen in this study. The Model has been validated by experts and practicable test conducted by teachers and a number of students at SMAN 10 Padang. Instruments to test validity and practicality are questionnaires, whereas to see the implementation of IGI model by teacher and student response using observation sheet and questionnaire. Data of validity and practicality were analyzed with kappa moment. To observe the implementation of learning model IGI done with percentage technique. The result of data analysis showed that Kappa moment for model validity is 0,81 with very high category of validity. The Kappa moment value for the model's practicality is 0.93 with a very high practicality category. The result of observation data analysis of the implementation of IGI learning model in SMAN 10 Padang shows that 96.8% learning model component can be done by the teacher. From the analysis of questionnaire data of student response to the implementation of learning with IGI model showed 94.7% of students stated the learning atmosphere of IGI model is fun, 89% of students said learning becomes easier and 91,3% students expressed motivated to learn using IGI model. The results of this study indicate that IGI learning model developed valid and practical use in chemistry learning in senior high school.
