A topological approach to formal limits supported by technology: What concept images do students form?
Page: 1667
The formal definition of the limit of a function was taught in a first-year calculus course usingopen intervals and a topological approach. Student understanding was supported with computer-based visualization tools. The concept image framework was used to interpret results of a pilotstudy in which data was gathered through concept maps and analyzed using categorical content
