AB This study aims to document the extent to which the use of digital technology enhancesand extends high school teachers’ problem-solving strategies when framing their teaching scenarios.The participants systematically relied on online developments such as Wikipedia to contextualizeproblem statements or to review involved concepts. Likewise, they activated GeoGebra’s affordancesto construct and explore dynamic models of tasks. The Apollonius problem is used to illustrateand discuss how the participants contextualized the task and relied on technology affordances toconstruct and explore problems’ dynamic models. As a result, they exhibited and extended thedomain of several problem-solving strategies including the use of simpler cases, dragging orderlyobjects, measuring objects attributes, and finding loci of some objects that shaped their approachedto reasoning and solve problems.
