Content Quality
Rating:
Strengths:
This calculator allows users to input two vectors and performs a variety of operations including an analysis of linear dependence, finding a linear combination of the two vectors, finding the orthogonal complement, and computing the vector product. Users can also select to view visualizations.
Concerns:
This tool could be improved by including review materials (or links to review materials) or more detailed explanations of the operations performed. The visualization is nice, but it would be helpful if the animation could be slowed down or paused.
Potential Effectiveness as a Teaching Tool
Rating:
Strengths:
