The Development of Integrative Assessment Model for the Subject of Bahasa Indonesia in Senior High School Students

The purpose of this research is to develop an integrative assessment model for the subject of Bahasa Indonesia that is effective for high school students. This research was a research and development with some stages proposed by Borg and Gall Sugiyono. Development of the model begun with preliminary studies, preparation of prototypes, validity test conducted by experts, testing of models in schools, and the analysis of testing results. The calculation for the validity of the model conducted by using Aiken analysis showed some findings. First, the validity of attitude assessment showed that 0.96 0.83 (very valid). Second, the validity of the knowledge assessment showed that 1.79 0.73 (very valid). Third, the validity of skills assessment showed that 0.865 0.860 (valid). In addition, the calculation for the model performed by using Coefficient Cohen’ Kappa also showed some findings as follows. First, the reliability of attitude assessment showed that 0, 87 0, 70 (very reliable). Second, the reliability of the knowledge assessment showed that 1.79 0.73 (very reliable).  Third, the reliability of skills assessment showed that 0, 71 0, 70 (reliable). The calculation for the practicality of the model conducted by five teachers proves several things. First, the practicality of attitude assessment showed that 3, 6 (very practical). Second, the practicality of the knowledge assessment showed that 3, 5 (very practical). Third, the practicality of skills assessment showed that 3, 7 (very practical). These findings demonstrate that integrative assessment model is very effective for assessing the ability of high school students.
