Furthermore, non-prototypical figures are particularly important when teaching geometry, but teachers and pre-service teachers still have problems defining them. For these reasons, we investigated whether there were differences in the way that pre-service mathematics teachers constructed and selected definitions for prototypical and non-prototypical solids. In particular, the commognitive framework was employed to investigate the differences in the discourse of 33 pre-service secondary-school teachers when constructing and selecting definitions in task situations that involved prototypical and non-prototypical solids. Moreover, we studied if some commognitive conflicts appeared in task situations involving non-prototypical solids but not in similar task situations involving prototypical solids. The findings show some differences between the pre-service teachers’ discourses in both types of task situations. Additionally, some commognitive conflicts appeared only in task situations with non-prototypical solids. Lastly, we classified those commognitive conflicts.</p></div>","PeriodicalId":47481,"journal":{"name":"Journal of Mathematical Behavior","volume":"75 ","pages":"Article 101170"},"PeriodicalIF":1.7,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0732312324000476/pdfft?md5=02bccb14ff2fe7c2ef9abd84783f1247&pid=1-s2.0-S0732312324000476-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141423150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the help of eye-tracking techniques, we investigated differences in focus and navigation when 15-year-olds read task texts in two distinct designs: a traditional design with written language presented in lines and all connections based on semantics; and a design including a graphic emphasizing links between symbols and explanations. While the graphic design was found to facilitate fast interpretation of the symbol–language connections, the traditional design seemed to encourage global reading, involving more text parts.

To reduce this influence (e.g., in testing situations), studies on linguistic simplification focus on modifying linguistic features. These studies show little or no effect on increasing test performance. An open question is whether a quantitative–exploratory approach with texts from a specific domain can be an additional model for reducing the linguistic influence on mathematical tasks. To answer this question, generalized linear mixed models were used to determine the effects of linguistic factors, the requirements of the items, and the effects of linguistic factors when differentiating the requirements of the items, while controlling for further person- and item-related effects. The results show that linguistic factors can have either a negative or positive influence on test performance.

Past studies show that people are more efficient with continuous visualizations than with discretized ones, but the specific reasons are unclear. Presumably, continuous visualizations highlight magnitudes more directly, while discretized ones encourage less efficient strategies such as counting. In two experiments, adults and children compared the magnitudes of continuous and discretized tape diagrams of fractions. In both experiments, participants answered more accurately, faster, and with fewer eye saccades when the visualizations were continuous rather than discretized. Sequences of saccades indicated that participants used counting strategies less often with continuous than discretized diagrams. The results suggest that adults and children are more efficient with continuous than discretized visualizations because they use more efficient, magnitude-based strategies with continuous visualizations.
