Abstract
E-Learning has become more and more popular in recent years with the advance of new technologies. Using their mobile devices, people can expand their knowledge anytime and anywhere. E-Learning also makes it possible for people to manage their learning progression freely and follow their own learning style. However, studies show that E-Learning can cause the user to experience feelings of isolation and detachment due to the lack of human-like interactions in most E-Learning platforms. These feelings could reduce the user’s motivation to learn. In this paper, we explore and evaluate how well current chatbot technologies assist users’ learning on E-Learning platforms and how these technologies could possibly reduce problems such as feelings of isolation and detachment. For evaluation, we specifically designed a chatbot to be an E-Learning assistant. The NLP core of our chatbot is based on two different models: a retrieval-based model and a QANet model. We designed this two-model hybrid chatbot to be used alongside an E-Learning platform. The core response context of our chatbot is not only designed with course materials in mind but also everyday conversation and chitchat, which make it feel more like a human companion. Experiment and questionnaire evaluation results show that chatbots could be helpful in learning and could potentially reduce E-Learning users’ feelings of isolation and detachment. Our chatbot also performed better than the teacher counselling service in the E-Learning platform on which the chatbot is based.
Highlights
We implemented it into our chatbot to show it is possible to use QANet as a conversational model. [49] shows that talking style plays an important role in human conversation, so we aimed to build our QANet model and response content to be as joyful to chat with as possible
In our QANet’s response context collection, we focused on generating relaxing, informative and entertaining responses to release stress and reduce feelings of isolation and detachment experienced by students
Responses from our chatbot are relatively close to what a real human would say, and chatting with our chatbot is a fun and entertaining experience
Summary
A. DEVELOPMENTS AND PROBLEMS OF E-LEARNING With the advancement of modern technologies, people’s lives are more convenient than ever before. Education and ways of learning have begun to change with the development of new technologies that improve learning efficiency and effectiveness. One such example of these new technologies is the Summit Learning Platform [1], an online learning tool that helps students set and track learning goals at their own pace. E-Learning is gaining popularity and is widely used in today’s modern education. In [2], many higher learning institutions, such as universities, are using E-Learning platforms because younger students are familiar with these new
