Peer Review

This site provides clear step-by-step solutions for evaluating limits.  Users can type in any limit problem. Mathtype symbols have been provided to aid in entering functions correctly. Users may also choose the solving method via a drop-down menu. Instructions about the estimated time to solve the problem with helpful guidance are also provided in this site.

If a user selects an invalid solving method, a message stating “We could not solve this problem by using the method: method name.”  One way this might be improved is to include a sentence describing when it would be appropriate to use the selected solving method.

Users can reference this site for a refresher in evaluating limits or to check solutions on homework or in-class activities.  It could be very helpful to students who are struggling with evaluating limits algebraically.

After viewing step-by-step solutions for a few problems, users are prompted to create an account.  Users are then prompted to purchase a monthly subscription.  Without purchasing a monthly subscription, users may only access the solution without the steps needed to reach this solution.  Hence, this site would not be a very effective teaching tool.

Entering in the function and limit information is quite easy. The step-by-step solutions look very nice when they can be viewed. Information with links to related formulas and solved examples on the right-hand side of the site are provided for users which are helpful.  

Engagement and interactivity are lessened when students cannot view the necessary steps to find a solution.
