E-learning involves teaching and learning using electronic technologies like computers and the internet. It allows students to learn remotely and at their own pace. Key benefits include flexibility, convenience, consistent content delivery, and the ability for students to monitor their own progress. However, some drawbacks are that unmotivated learners may fall behind and students can feel isolated without in-person interaction. E-learning methods include synchronous learning like online lectures and asynchronous self-paced courses. Teachers have an obligation to utilize available technologies and encourage collaborative learning to lay the foundation for lifelong learning. Blended learning combines e-learning tools with traditional classroom learning for maximum effectiveness.
