USE OF SOFTWARE LINDO WITH GUIDED DISCOVERY LEARNING METHOD TO INCREASE THE OTIVATION OF STUDENT LEARNING IN LINEAR PROGRAM COURSE

Abstract

Mathematics education class of  2013 students at University of Muhammadiyah Jakarta have less motivation to study. This can be inferred from the grades of the students in Linear Algebra Course. Almost all of students got E in linear algebra. Some students not motivated in  the explanation of the lecture and they not followed the learning process. The learning process is still centered on the teacher, so the students seem waiting the lecture from the teacher. Therefore, we conduct Classroom Action Research in the Linear Program  course to the class of 2013 to improve students’ motivation. The Classroom Action Research use guided discovery method assisted Software LINDO. Linear program is a mathematical method of allocating scarce resources to achieve a single goal such as maximizing profits or minimizing cost.  Guided discovery method is a development method of Pieget Constructvism theory, that is a learning that emphasizes the importance of students sctivities who are active in constructing his knowledge. In general, software LINDO will provide direct experience for students to formulate, solve and verify a valid formula based on the solution method. In our result, There is an increase 2.82% on students motivation from Cycle I (69.46%) to Cycle II(72.28%), and there is an increase 2.83% from Cycle II (72.28%) to Cycle III (75.11%). The students’ motivation in Linear program course has reached 75.11% using this approach. Moreover, the percentage of students’ interest of the approach assisted   Software LINDO is 93.75%.
