ABSTRACT This article is a summary of some second year research reports of the three years research plan financed by Directorate of Research and Community Service (DRCS). This research aims to develop a learning model based on Attention, Relevance, Confidence and Satisfaction (ARCS) theory oriented towards Indonesian Qualification Framework (IQF) that was applied to mathematical statistics course. The stages of development of this learning model were following Plomp-s learning model development process.Plomp-s model has three stages namely: (1) preliminary stage; (2) prototype stage; (3) assessment stage. After went through experts validation process, appeal validation, and several revisions, in this second year,the implementation of this research had stepped on the beginning of assessment stage, limited trial. At this stage, technical assessment was carried out using practicality and effectiveness tests. Main focus of this stage is on field trials to find out whether the prototype model and all learning tools that have been produced are practical and effective. The field trials were conducted at three universities in North Sumatera, namely Undergraduate and Graduate School of State University of Medan, Undergraduate and Graduate Schoolof Muslim Nusantara Medan University and Graduate Schoolof Asahan University. This paper is only reporting the field trial-s result done in Undergraduate School of Mathematics Education Program in State University of Medan. In State University of Medan, the trial was held twice. First was in class A followed by 21 students and second was in class B followed by 40 students. From the results of the first and second trials obtained that all of the learning toolsconsist of student textbook, lecturer handbook, student worksheetss, and other supporting tools indicated high validity. Moreover, there is an enhancement of students-ability to understand about mathematical statistics. Highest score in the first trial significantly increased from 80.5 to 94.5 in the second trial. While lowest score also significantly increased from 40,5 to 58,0 and average score increased from 63.5 to 74.4 in the second trial. Keyword: learning model, ARCS theory, IQF
