Content Quality
Rating:
Strengths:
The calculator allows you to select the size of the initial matrix (up to 10x10) and the individual entries. It will then calculate the reduced row echelon form and show intermediate steps.
In addition there are links to other calculators and a link for feedback.
Concerns:
This site contains several advertisements which might be distracting.
Potential Effectiveness as a Teaching Tool
Rating:
Strengths:
The step-by-step solutions help users to see exactly how to find the reduced-row echelon form of their matrix. Viewing these steps can lead to a better understanding of the process of Gauss-Jordan Elimination. This would be a great resource for allowing students to check their work.
The page also includes an example and explanation for solving a system of linear equations.
Concerns:
None
