Abstract
Many high school students find algebra difficult because it requires comprehending abstract concepts, performing symbol and sign manipulation, and solving multi-step problems. Graphing calculators can visualize algebraic expressions and equations, and make learning more interactive. We conducted an experiment in which Desmos online graphing calculator was used to augment the algebra lessons of tenth-standard students. The students were taught about polynomials, linear and quadratic equations, and arithmetic progressions during an intervention period lasting seven weeks. We found that properly integrating the graphing calculator with classroom sessions and homework helped the students to perform better in the post-test and also retain the concepts. The students found the graphing calculator to be easy to use and helpful in learning, which increased their interest in algebra and encouraged them to practice algebra regularly.
