The COVID-19 pandemic prompted a shift to remote learning, offering students at UNLV the option to take Precalculus and Calculus either in person or through web-based live classes. While online learning provides greater flexibility, it also presents challenges, particularly in terms of student motivation and communication with instructors. This presentation explores strategies to enhance the interactivity and engagement of web-based live classes, emphasizing the need to adapt the structure and delivery methods used in traditional in-person classrooms. Drawing from my own experience teaching these courses, I will share techniques for creating effective online learning environments for Precalculus and Calculus at UNLV. Key elements of my web-based live Precalculus and Calculus classes include: • Pre-Class Preparation: Uploading lecture materials and corresponding videos in advance to allow students to engage with the content before class. • Historical Context: Starting each lecture with a brief historical overview to provide relevance and context to the material. • Interactive Problem Solving: Discussing the main concepts of the lecture and collaboratively solving challenging problems. • Proof Techniques: Demonstrating mathematical methods used to prove key statements from the current lesson (a critical element, especially with the rise of AI technologies). • Real-Time Feedback: Using audience response systems (e.g., Poll Everywhere, iClicker) to conduct interactive quizzes and polls during the class. Additionally, I’ve integrated dedicated discussion sessions into the course schedule. During these sessions, we not only review homework solutions but also explore how mathematical techniques can be applied to real-world problems. This approach helps students see the practical value of the concepts they are learning, bridging the gap between abstract mathematics and real-life applications in their future careers.
