Wiki is an online tool that is great for teachers to use in the classroom. Essentially it is a place where the teacher can open projects and allow for students to contribute and edit it. It allows for the students in a classroom to not only take in the information they are being given, but to also contribute to the compilation of the lesson and the material that they are learning. It is a great tool for classroom participation. It allows each student to be engaged and to contribute to the project. It can be hard because anyone can contribute anything to the project, but as long as proper expectations are assigned it can be easily monitored. It can be used for research projects like researching an author or a book. It can even be used for scientific projects.
