Development of Android Based Instructional Media of Algebraic Tiles for Quadratic Equation

Abstract

This research and development aims to develop the android based instructional media of algebraic tiles for quadratic equation. The media created must meet the criteria of valid, practical, and effective to assist the student in understanding the factoring in quadratic equations. The research model used in this research is 4D model developed by Thiagarajan. This model is used and modified into 3 stages only, those are (1) define stage; (2) design stage; and (3) development stage. The resulting product is named FICTION (Factorization of Quadratic Equation) which has apk as it's extension and can be deployed and installed on a minimum android-based smartphone on version 4.0 / 4.1 (Ice Cream Sandwich). After trials, it can be conclude that FICTION is valid with level of validity 3.83, practical with level of practicality 3.1, but ineffective because none of students could pass the score minimum criteria.
