The use of chatbots in eLearning

What are chatbots that use artificial intelligence and how can they be used in eLearning?

In the rapidly evolving landscape of education, technological advancements have played a vital role in transforming traditional learning methods. One such innovation that has gained significant attention and adoption is the use of chatbots in eLearning. These virtual assistants have revolutionized the way students access information, engage with course content, and receive assistance. Unlike traditional classrooms or early eLearning models, which relied primarily on static content, chatbots are emerging as the technology capable of introducing dynamic, interactive and personalized learning experiences. This innovation uses artificial intelligence (AI) and natural language processing (NLP) technologies to communicate and facilitate learner engagement, provide instant feedback and support students throughout their learning journey. 

In this article we will delve into the world of chatbots in eLearning, analyzing their applications, advantages, challenges and their case study potential.

What are chatbots?

Chatbots are computer programs driven by artificial intelligence and designed to simulate a human conversation. They use natural language processing technologies to understand and respond to natural language input from users. In the context of eLearning, chatbots are used to interact with students, answer questions, offer assistance and provide information. To be more specific, chatbots can create a learning experience similar to one-on-one teaching, making social and interactive learning “in dialogue” with a device possible. In the L&D sector, a chatbot acts as a virtual teaching assistant and can provide timely training support by providing content, such as links, images, videos, etc.

Types of chatbots in eLearning

To better understand how this technology is used and the potential of its application in eLearning, let's explore some types of chatbots used in the sector below:

  • Virtual Tutors: Virtual tutors are chatbots programmed to act as knowledgeable guides for students. They assist students in understanding course materials, answering questions, and providing explanations.
  • Course Assistants: Course Assistants are chatbots that provide administrative support. They can help with tasks such as registration, course scheduling, or provide information on course logistics.
  • Custom learning guides: These chatbots can be very complex and use data analytics to track student progress and recommend personalized learning paths, including additional resources and exercises.
  • Grading & Feedback Bots: Grading & Feedback Bots help grade assignments, quizzes, and exams, providing immediate feedback to students. They can also help teachers generate reports and analyses. This type of bot may have limitations in evaluating qualitative tasks such as essays, essays, or presentations.
  • Language learning bots: Language learning apps often use chatbots to help students practice speaking, vocabulary, and pronunciation. Given the high capacity for interaction with the user, chatbots are very useful for learning new languages.
  • Career advice bots: Some institutions use chatbots to assist students in career planning by suggesting suitable courses and career paths based on their interests and skills.
  • Mental health and wellbeing support: In recent years, chatbots have been employed to provide mental health support, offering resources and guidance to students suffering from stress or anxiety on how to seek assistance.

The benefits of using chatbots in eLearning

Integrating chatbots into eLearning environments offers numerous benefits for both students and educators. Here are some of the main advantages:

  1. Accessibility and convenience. Chatbots offer 24/7 accessibility to course materials and support, making learning possible at the students' needs and pace. Not only can students seek assistance and access resources when and where they need it, but they are also supported in doing so, significantly reducing barriers to learning.
  2. Instant feedback and support. Chatbots provide immediate answers to questions and instant feedback on assignments and quizzes. This immediate feedback loop improves the learning experience and helps students identify and correct their mistakes early.
  3. Scalability. Instructors can efficiently manage large classes with the help of chatbots. The scalability of these AI-driven assistants ensures that every student receives the attention and support they need, even in massive open online courses (MOOCs).
  4. Personalized learning. Chatbots analyze student data to create personalized learning paths. By tailoring content and resources to individual needs, chatbots can help students realize their full potential and achieve learning goals more effectively.
  5. Involvement and motivation. Engaging with chatbots in natural language conversations can make the learning process more enjoyable and less daunting. This increased engagement can increase student motivation and retention.
  6. Data-driven insights. Chatbots collect a large amount of data about student interactions, allowing teachers to learn about students' learning patterns, preferences, and areas of difficulty. This data-driven approach allows teachers to continually improve their teaching methods.
  7. Cost effective. While chatbots require an initial investment to develop and deploy, they can ultimately reduce administrative and support costs, especially at institutions with a high volume of student requests.
  8. Chatbots are more patient. While on the one hand a bot offers a less human relationship than with a real teacher, on the other hand it never loses patience. This element is a useful ability to offer learning in line with student needs.

Challenges and considerations

While chatbots offer immense potential in eLearning, there are challenges and considerations that educators, institutions, and students must address:

  1. Quality of content

Chatbots can provide information, but the quality of that information is critical. Ensuring that the content provided is accurate and up-to-date is essential for effective learning. Since we are not yet able to fully understand artificial intelligence, we prefer to use this technology as a support.

  1. Natural language understanding

Chatbots must have strong NLP skills to understand and respond to students' different ways of expressing themselves. Overcoming language barriers and understanding dialects and accents is a challenge.

  1. Privacy and data security

Collecting and analyzing student data for personalization raises concerns about privacy and data security. Institutions must have strong policies and safeguards in place to protect sensitive information.

  1. Integration with existing systems

Integrating chatbots into existing eLearning platforms and systems can be complex. Technical and compatibility issues need to be addressed to ensure a smooth user experience.

  1. Ethical considerations

The use of chatbots in eLearning also raises ethical questions, such as the potential for bias in content recommendations and the impact of AI on human-to-human interactions in education. The quality of the information that an AI is able to offer is linked to the type of information that is "inserted" into it; however, there are no laws that impose restrictions or recommendations on the type and quality of information on the manufacturers of these technologies. Furthermore, although the use of chatbots can assist the student better than a human, it is a technology that limits human contact and should not replace interaction with the teacher or other students.

  1. User Acceptance

Students and educators must be willing to accept chatbots as part of the learning process. Resistance to this technology can hinder its effectiveness.

Case Studies: Successful Implementation of Chatbots in eLearning

To better understand the impact of chatbots in eLearning, let's explore some case studies where chatbots are the protagonists:

  1. Georgia State University's “Pounce” chatbot

In 2015, Georgia State University in the United States was faced with a big problem: the dropout rate after the first year had increased from 12% to 19% in just a few years. To solve this problem, Georgia State University realized it needed to better serve students and implemented a chatbot called “Pounce.” The role of this chatbot was to support students with course enrollment, financial aid to pay for their studies and registration. The chatbot helped the university increase student retention rates by 5%, demonstrating the value of chatbots in administrative support. Not only that, Georgia State has shown that student performance increases when classes use chatbots to keep them connected. Receiving direct text messages about classwork, academic supports, and course content increased the likelihood that students would earn a B or better and, for new students, increased the likelihood of passing the course.

  1. Duolingo Language Learning Chatbot

Language learning platform Duolingo uses chatbots to provide conversation practice for students. This company was the first or most popular to use chatbots to teach languages to students, and this interactive approach has contributed to the popularity and effectiveness of Duolingo in language training, so much so that it has become a case study for numerous scientific researches. Some of these would demonstrate that the Duolingue method would be more effective than university courses. Other research corroborates and still others deny this thesis, but what is certain is that the popularity of the app and the data emerging from independent research demonstrate that the use of chatbots for language learning offers many advantages for students and is intriguing many experts in the world of training.
