Student’s learning outcomes through the application of guided inquiry learning model based on scientific approach in fundamental chemical laws

The discovery learning model is a learning model which can be implemented in the Curriculum 2013 in Indonesia. However, the student’s learning outcomes of chemistry subject at SMAN 7 Palu using this learning model are not satisfactory because the students’ scores have not passed the passing grade. Therefore, it is needed other learning model that has the characteristics of the scientific approach to be implemented. The purpose of this study is to see whether the application of the guided inquiry learning model based on the scientific approach in Fundamental Chemical Law topic can provide better learning outcomes for students in class X of SMA Negeri 7 Palu compared to the discovery learning model. The research method was a quasi-experimental study by conducting the experimental group and control groups. The results obtained by this study, to be precise the learning achievement data reached 92,1% to 96,05% in the experimental class 1 and 91.35% - 94.75% in the experimental class 2. While student’s learning outcomes obtained an average of 56,48 and 46,25 with a standard deviation of 11,07 and 11,98. These values prove that the guided inquiry learning model to provide better learning outcomes compared to discovery learning. Furthermore, based on the two samples t-test results obtained, it was found that - t table + t table (-1.68 +1.68) with a significant level (α = 0.05) and degrees of freedom 41. Consequently, it can be inferred that the implementation of the guided inquiry learning model based on the scientific approach in the Fundamental Chemistry Law topic can provide better learning outcomes for class X students of SMA Negeri 7 Palu.
