TRIGONOMETRY MODULE DEVELOPMENT APPROACH USING APTITUDE TREATMENT AND INTERACTION (ATI) FOR EDUCATION AND TEACHER TRAINING FACULTY STUDENTS AT MATHEMATICS DEPARTMENT OF STATE ISLAMIC UNIVERSITY OF SUSKA UIN RIAU

This study aims to develop trigonometry module using the valid, practical and effective ATI approach. This research method used Research Development Approach. It is a development model of IDI (Instructional Development Institute). The study consisted of three stages: front-end analysis, prototype stage and assessment stage. Activities done in this front and analysis involved analyzing the measured material analizing the math text books especially Trigonometry, reviewing literatures abaut modules learning, interviewing it math peers with in this sense were lecturers, and learning the characteristics of the students. According to the analysis finding of front and analysis has been obtained the prototype Trigonometry module which is then consulted by the experts. This prototype was further validated by five experts consisted of three instructional design experts and 2 content experts. At the practices stage the module was tested to student the state semester. The testing has observed by two (2) observers from lecturers. The effectivity of module observation has done together with the practicalities. The effectivity observed has about student activity, motivation, and student learning achievement. The finding of this research showed that: (1) The designed Trigonometry module was valid (content, construct) from the instructional design experts and mathematics education expert, (2) The Trigonometry module can be used by students lecturers without any significant obstacles, in other words, it used practically based on the observers evaluation and the lecturers, and (3) trigonometry module effective with has shown by learning activities, motivation, and the high student learning achievement after following the learning teaching process.
