Digital Teaching Aid Development to Answer Challenges in Learning Quadratic Equation in Indonesia


Quadratic equation is considered as the most challenging mathematics topic for secondary high school students in various countries, including Indonesia. Studies have been done to identify challenges in the teaching and learning of this topic. The three most common challenges discovered include dull teaching method that does not encourage active learning, difficulty in obtaining conceptual understanding on quadratic equations and its associated information, and difficulty in interrelating different solution methods, including the factor form, vertex form and graphical representation. Teaching aid in the form of digital technologies is commonly proposed to address these challenges. However, existing media may not fully address all the discovered challenges. Moreover, digital media adds additional challenges in the form of various distractions that can hinder students’ focus in learning the material. Therefore, this paper discusses the development of a digital teaching aid that is specifically designed to help learn quadratic equations by mapping challenges to features of the digital media. As a result, an offline computer software has been developed with the following five features: it supports both English and Bahasa Indonesia, it has well-defined input mechanisms for ease of use, it is able to generate graph automatically from a given quadratic equation and highlight it with associated information of the equation, it has an “Exercise” menu with a simple game to maintain students’ interest, and it has three “Form” menu to interrelate various forms of a quadratic equation complete with sliders to experiment with coefficients of a quadratic equation.
