YouTube is a useful classroom resource that allows students to upload and share videos of their work and presentations. It is particularly helpful for physical education classes where students can watch video clips demonstrating skills for sports like touch football. However, the wide variety of videos on YouTube can also be distracting if students are working independently or in small groups. Wikipedia is also useful as it provides a broad depth of information on many topics for research assignments. While it offers instant updates on current events, inaccuracies sometimes exist since contributors are not always experts and information may not be immediately reviewed.
