Teachers are always in search of lessons, units, and activities that will help them teach. In the decades since web 2.0 tools arrived on the world wide web, teachers have been able to (for example) create online quizzes and make them available to students; after they take the quizzes, teachers can then check their progress. There are a number of web 2.0 tools that have been developed for and adapted for teaching and assessment by teachers. These tools are dependent on keeping some information about the users, and this means site publishers are responsible for securing permission to collet this data under the Children’s Online Privacy Protect Act. As a result, the terms of service of the sites do not allow use of the site by individuals younger than 13. While this may seem an insignificant threat to networks security, educators and IT professions in schools have a responsibility to ensure they are confident the providers of these services are safeguarding students data. Unfortunately, many educators who find excellent teaching resources cannot use them especially with younger students as they violate local procedures. It is always best to check with the local IT professionals to see if such tools are acceptable under local policies and procedures.
