II. Types of Active Learning
There are many different types of active learning, each with its own advantages and disadvantages. Some of the most common types of active learning include:
- Peer instruction: In peer instruction, students work in small groups to solve problems or answer questions. The instructor then leads a discussion of the solutions, helping students to learn from their mistakes and from each other.
- Problem-based learning: In problem-based learning, students are presented with a real-world problem and then work in groups to find a solution. The instructor provides guidance and support, but the students are ultimately responsible for finding a solution.
- Project-based learning: In project-based learning, students work on a project over an extended period of time. The project can be anything from a research paper to a website to a piece of art. The instructor provides guidance and support, but the students are ultimately responsible for completing the project.
- Simulation-based learning: In simulation-based learning, students use simulations to learn about a particular topic. Simulations can be used to create a realistic environment in which students can practice their skills and learn from their mistakes.
- Game-based learning: In game-based learning, students learn by playing games. Games can be used to teach a variety of topics, from math to science to history.
The type of active learning that is best for a particular course will depend on the learning objectives, the students’ prior knowledge, and the instructor’s preferences.
