In assuming that problem-solving is a synchronous activity of mathematization and expression of mathematical thinking we take our proposed Mathematical Problem Solving with Technology (MPST) model to analyze the processes of solving-and-expressing-problems.\u00a0Resorting to qualitative methods for data collection and analysis,\u00a0we report on the case of an 8th\u00a0grader working on a covariation problem to examine the role that paper-and-pencil and digital tools play in the development of a conceptual model of the situation. We found that the resources used throughout the solving-and-expressing activity influenced the depth of the conceptual model developed, within a process of progressive mathematization. Whereas paper-and-pencil led to the emergence of a conceptual model based on exploring particular cases, the digital transformation of the solution was triggered by the process of communicating its mathematical justification and expanded the previous model. Moreover, the complexity of this activity is evidenced by its multiple sequences of processes. Finally, the integration process seems crucial as the concomitant use of technological and mathematical resources precedes major advancements in the expansion of the conceptual model.<\/jats:p>","DOI":"10.22342\/jme.12.1.12940.113-132","type":"journal-article","created":{"date-parts":[[2021,1,15]],"date-time":"2021-01-15T23:14:10Z","timestamp":1610752450000},"page":"113-132","source":"Crossref","is-referenced-by-count":3,"title":["DIGITAL TOOLS AND PAPER-AND-PENCIL IN SOLVING-AND-EXPRESSING: HOW TECHNOLOGY EXPANDS A STUDENT\u2019S CONCEPTUAL MODEL OF A COVARIATION PROBLEM"],"prefix":"10.22342","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4768-2080","authenticated-orcid":false,"given":"H\u00e9lia","family":"Jacinto","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0746-7258","authenticated-orcid":false,"given":"Susana","family":"Carreira","sequence":"additional","affiliation":[]}],"member":"9608","published-online":{"date-parts":[[2021,1,16]]},"container-title":["Journal on Mathematics Education"],"original-title":[],"link":[{"URL":"https:\/\/ejournal.unsri.ac.id\/index.php\/jme\/article\/viewFile\/12940\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/ejournal.unsri.ac.id\/index.php\/jme\/article\/viewFile\/12940\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,1,15]],"date-time":"2021-01-15T23:14:11Z","timestamp":1610752451000},"score":1,"resource":{"primary":{"URL":"https:\/\/ejournal.unsri.ac.id\/index.php\/jme\/article\/view\/12940"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,1,16]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2020,12,17]]}},"URL":"https:\/\/doi.org\/10.22342\/jme.12.1.12940.113-132","relation":{},"ISSN":["2407-0610","2087-8885"],"issn-type":[{"type":"electronic","value":"2407-0610"},{"type":"print","value":"2087-8885"}],"subject":[],"published":{"date-parts":[[2021,1,16]]}}}
