Abstract
With the appearance of a great amount of knowledge of different fields, the explosion of knowledge has taken place. How to get information quickly and efficiently has become extremely important. Furthermore, it is necessary for modern people to learn much more since the integration of different technologies in different fields has become more and more common; however, it is not convenient for modern people to learn due to the limit of time and place. Therefore, online learning platform has been a convenient way for learning in recent years. There are many online learning platforms with a great number of convenient functions inclusive of online discussion forum, online face-to-face discussion room, and so on. Plenty of institutes developing online learning platforms cooperate with well-known professors all over the world, providing a good approach to learn knowledge in different fields. However, the grading tasks could be difficult for teachers since a great number of open-answer quizzes/assignments are needed to be assessed. For the purpose of solving the assessment problem, we propose a peer grading approach and implement on the real online learning platform to do experiments to get a better assessment result which might be similar to the experts’ assessments. This mechanism not only solves the assessment problem, but also enhances the learning effectiveness of students by their review in the assessment process. Nevertheless, how to get an objective assessment by peer grading is the main topic in this thesis. With the popularity of online learning platforms, we modern people can learn more and enhance our capabilities in a quick and convenient way when facing with the explosion of knowledge and information, and this will definitely promote the advancement in science and technology again.
