<p>Course evaluations are very useful for the evolution of any specific course. Course revisions should be ongoing for as long as the course is offered and can even produce different versions of the course that can be more suitable in different situations. A class with a low number of students may benefit from a certain version of the course that was developed and tested on smaller class sizes. There may even be a version of the course that is more suitable for larger class sizes or in the event of Holiday or Weather related schedule interruptions. Formative evaluations give the instructor the opportunity to make midcourse revisions and test outcomes more quickly. These are useful for instructors as course corrections can be made immediately to avoid any negative outcomes. Summative evaluations give the instructor time to consider more involved changes that can possibly affect the curriculum of the teaching tools.&#160;</p>
