Potential negative impacts include those common to any user-oriented software system. If the system is too complicated, users have little incentive to use it. Professors may not understand an overly complex interface when creating their tutorial pages. Furthermore, in regards to data security, there may be potential negative impacts due to student information and quiz scores being leaked. There are potential security issues with private person-toperson chat. Also, there could be potential abuse. For example, someone pretending to be a professor could trick students into doing things that could compromise their security (e.g. passwords, remote access to computers).
Another negative impact regards the size of electronic tutorials, particularly those with many images. If a tutorial author happens to use an image format that requires a large amount of storage, the tutorials themselves could be overly large, encumbering transfer speed and imposing constraints on storage constraints on the machines where the tutorials are stored. And lastly, there is a subtle issue regarding the accuracy and completeness of the tutorials and quizzes that the instructors create.
