The document discusses three articles on using technology to enhance learning and student engagement. The first article examines the benefits of blended learning approaches that combine online and in-person elements. The second discusses how student attention declines during long lectures and can be improved with breaks and varied activities. The third explores how using iPods in the classroom can make learning more engaging for students by connecting it to their interests and technology use outside of school. All three argue that direct interaction and communication between students and instructors is important for effective learning.
