Content Quality
Rating:
Strengths:
This site provides an interactive, user friendly applet to visualize the intermediate value theorem. Students can input mathematical functions of their choice. This site offers a great help for students of Calculus I who want to visualize the intermediate value theorem and they can also use it to check the answers of their course assignments and projects when they input their own mathematical functions. It allows users to input their own functions and can manipulate interval endpoints for exploration. This site can be included as a part of lecture or as an extra online tutorial for students.
Concerns:
This site suffers from clear instructions for students to follow. The applet might also be improved by including the option to displaying the coordinates of points on the screen.
Potential Effectiveness as a Teaching Tool
Rating:
Strengths:
This applet is a great tool for helping students to visualize the Intermediate Value Theorem. Both instructor and student can use this site in the Calculus I class in lectures or assignments. It could be used for an in-class demonstration or incorporated into a group activity.
Concerns:
There is no option to use an equation editor to enter equations. Some students do not know how to write functions correctly. This may make it a bit more difficult for some users to enter equations correctly.
Ease of Use for Both Students and Faculty
Rating:
Strengths:
This applet is intuitive and easy to use.
Students and instructors can access this applet easily.
Concerns:
This site does not provide guidelines or instructions for students who are independently studying the materials. Therefore, providing brief instructions will definitely improve this applet.
