Module 2: Machine Learning Basics

Introduction and Key Takeaways

In this module, students will delve into the fundamental principles of machine learning, a pivotal component of artificial intelligence that enables systems to learn and improve from experience without being explicitly programmed. By the end of this module, students will be able to recall and identify key machine learning concepts and terminologies, understand the basic functioning of machine learning algorithms, and recognize their applications within educational settings. This foundational knowledge will serve as a stepping stone for exploring more advanced AI topics in subsequent modules.

Content of the Module

Machine learning is a subset of artificial intelligence that focuses on developing algorithms that allow computers to learn from and make predictions or decisions based on data. At its core, machine learning involves training a model on a dataset to recognize patterns and make informed decisions. This module will introduce students to essential concepts such as supervised learning, unsupervised learning, and reinforcement learning. Supervised learning involves training a model on a labeled dataset, where the algorithm learns to map inputs to desired outputs. Unsupervised learning, on the other hand, deals with unlabeled data, and the model attempts to identify inherent structures or patterns within the data. Reinforcement learning is a type of machine learning where an agent learns to make decisions by interacting with an environment to maximize a reward signal.

Students will also explore the various stages of a machine learning project, including data collection, data preprocessing, model selection, training, validation, and evaluation. Emphasis will be placed on understanding the importance of data quality and the role it plays in the accuracy and reliability of machine learning models. Furthermore, students will be introduced to common algorithms such as decision trees, support vector machines, and neural networks, with a focus on their applications in educational contexts. For instance, machine learning can be used to develop intelligent tutoring systems that adapt to individual student needs, enhancing personalized learning experiences.

Exercises or Activities for the Students

To reinforce the concepts covered in this module, students will engage in a hands-on activity where they will work with a simple dataset to train a basic machine learning model. Using a user-friendly platform such as Google Colab or Jupyter Notebooks, students will perform data preprocessing, select an appropriate algorithm, and evaluate the model’s performance. This exercise will provide students with practical experience in applying machine learning techniques and understanding the challenges involved in model development. Additionally, students will participate in a group discussion to brainstorm potential applications of machine learning in education, encouraging them to think creatively about how these technologies can address real-world challenges.
