Dr. Syukrul Hamdi delivered material related to his pubish article in the International Journal of Instruction. The article was titled Developing a Teslet Model for Mathematics at Elementary School. The purpose of the research conducted by Dr. Syukrul Hamdi, namely developing a Mathematical test instrument for the Teslet model for classroom assessment in elementary schools. The study was conducted in East Lombok, with a total sample of 711 elementary school students. Dr. Syukrul Hamdi ie there are differences in the score of the results of the assessment using the Testlet compared to using multiple choice, with t values ​​of 7,864.
