Content Quality
Rating:
Strengths:
This calculator allows users to quickly find solutions to quadratic equations by entering the values of the coefficients “a”, “b”, and “c”. The solution is shown using the quadratic formula. A graph is provided, and users can choose to view a variety of information on the graph, including the locus and axis of symmetry. Links more information on solving quadratic equations, including example problems, are provided.
Concerns:
The review material could be improved by stating the standard form of quadratic equation at the top of the site to clarify where the “a”, “b”, and “c” come from. The site does contain ads which may be a bit distracting since some of the adds are videos.
Potential Effectiveness as a Teaching Tool
Rating:
Strengths:
This tool could be used for in-class demonstrations and would be very helpful for students who are learning to solve quadratic equations or looking for review.
Concerns:
For quadratic equations where at least one coefficient is 0, users need to enter a 0 for the coefficient in order for the graph to display properly.
Ease of Use for Both Students and Faculty
Rating:
Strengths:
The calculator layout is simple and easy to use. Also it is visually appealing.
Concerns:
The site does contain ads which may be a bit distracting since some of the adds are videos.
