Automatic multiple choice answer sheet marking mobile application.

Abstract

Multiple-choice questions are a widely-preferred tool used to evaluate learner’s academic performances in education institutions all over the world. However, in situations when the number of individuals is large, this exercise becomes a monotonous, tedious, and time consuming piece of work that is susceptible to errors. Due to the mistakes committed by instructors while marking, students are awarded wrong grades. This project was therefore aimed at developing a mobile application that would solve the above problem by enabling instructors scan the reference/ key (marking guide) answer sheet once which is stored in the database and then take pictures of students’ handwritten-on answer sheets which are used to extract characters, process and recognize them by the OCR and OCR engines. These extracted characters are cross referenced by the marking algorithm to mark the students’ performance hence saving lecturers’ valuable instruction time. The work is arranged mainly in six chapters, chapter one includes the introduction of automatic multiple-choice answer sheet marking mobile application. Chapter two discusses the literature related to the system, chapter three illustrates the methodologies used in coming up with the working prototype of the system, chapter four includes system design and analysis, chapter five contains the implementation and testing of the system and chapter six contains the summary of the work, challenges, critical analysis, proposals and recommendations.
