Abstract

Abstract. Islamic University of Jember is a private university that organizes education in the Jember city. The implementation of the student exam at Islamic University of Jember, especially Mathematics education, is held 2 (two) times at years, that are the exam in old semester and the exam in even semester. Each exam will be guarded by 1 (one) lecturer, while 1 lecturer can be a examiner for several semester exam in one day, so that in the preparation of the thesis examination schedule must consider the time availability of each lecturer who will test. The preparation of the semester examination schedule at the Islamic University of Jember in mathematics education is manually, so that the overlapping semester exam schedule is still found. The overlapping exam schedule resulted in the implementation of the exam not being maximal, so that a technique was needed in the preparation of the thesis examination schedule. One technique that can be used to form a schedule is vertex coloring graph. The results of this study show that vertex coloring can be applied in making the semester examination schedule by giving better scheduling results than the previous method. The resulting semester exam schedule no longer shows an overlapping exam schedule so that the implementation of the semester exam runs better. Keyword : Scheduling, Vertex Coloring, Exams.

Abstract

Abstract. This study aimed to describe the process and to develop analytical thinking ability instruments referring to the Thiagarajan Model known as the Four-D Model (Model 4-D). The Thiagarajan Model consists of four stages: define, planning, design, and disseminate stages. Data analysis consisted of instrument validation analysis, instrument reliability, practicality and effectiveness of instruments and analysis of teacher response data on the results of instrument development. Based on the results of the analysis, the instrument developed reached high level of instrument validation by experts with a validity coefficient of 0.748 and high level of instrument reliability with a reliability coefficient of 0.78. In addition, the degree of practicality was in the high category with a degree of coefficient (IP) = 4. It also reached high degree of effectiveness with a degree of coefficient (IE) = 4.6. The teacher's response to the development of the instrument was very good with a teacher response of 90%. Keywords: Analytical thinking skills, problem solving questions
