Dorner, Christian – International Journal of Mathematical Education in Science and Technology, 2021
This paper deals with a set of geometrical problems for mathematical problem-solving at different difficulty levels. All of these are presented as national flags and one has to investigate invariant area proportions when changing the locus of any corner of the flag. This dynamic element suggests the usage of dynamical geometry environments.…

Van Dyke, Frances; Malloy, Elizabeth J.; Stallings, Virginia – Canadian Journal of Science, Mathematics and Technology Education, 2014
This article discusses an activity designed to encourage writing to learn in mathematics. There were three stages of data collection. An assessment, requiring basic algebra only, was completed by 118 undergraduates from statistics and calculus courses. Students were given summaries of all participant responses, along with the correct answers.…
