Improving the Graph Interpretation Competencies of Preservice Secondary Science Teachers Through Long-Term Independent Inquiry Project Work

Résumé fourni par la source

Understanding graphs is a necessary component of understanding science communication. Previous work indicated that pre-service science teachers have difficulty with this sort of data interpretation (Bowen, Bartley & Melville, 2025; Bowen et al., 2016). It is suggested that experience in conducting independent field work may be necessary to increase the competency of pre-service science teachers in graphing practices. A previous study (Bowen & Roth, 2005) suggested that an improvement in competency was not gained from engaging in a short-term inquiry project, much as short-term engagements have not improved Nature of Science understandings (Edgerly et al., 2023; Akerson et al., 2006, 2017). Evidence from this study suggests participation in an extended inquiry project did improve several aspects of discourse over and about graphs. Three positive outcomes from engaging in a long-term inquiry project are identified: (1) There was an improved canonical use of inscriptions as demonstrated by a higher use of abstract transformations, (2) There was an increase in the use of external referents, (3) There was an increase in the use of personal experiences to make sense of the components of the data problem and to interpret the relationships. Implications of these findings for preparing science teachers are discussed.
