Direct linkPetritis, Steven J.; Kelley, Colleen; Talanquer, Vicente – Chemistry Education Research and Practice, 2021
Research on student argumentation in chemistry laboratories has mainly focused on evaluating the quality of students' arguments and analyzing the structure of such arguments ("i.e." claims, evidence, and rationale). Despite advances in these areas, little is known about the impact of activity framing on the nature of student…

Talanquer, Vicente – International Journal of Science Education, 2018
One of the central goals of modern science and chemistry education is to develop students' abilities to understand complex phenomena, and productively engage in explanation, justification, and argumentation. To accomplish this goal, we should better characterise the types of reasoning that we expect students to master in the different scientific…

Scalco, Karina C.; Talanquer, Vicente; Kiill, Keila B.; Cordeiro, Marcia R. – Journal of Chemical Education, 2018
We present the results of a qualitative research study designed to explore differences in the types of reasoning triggered by information presented to chemistry students in two different formats. One group of students was asked to analyze a sequence of images designed to represent critical elements in the explanation of a target phenomenon.…

Yan, Fan; Talanquer, Vicente – International Journal of Science Education, 2015
Research in science education has revealed that many students struggle to understand chemical reactions. Improving teaching and learning about chemical processes demands that we develop a clearer understanding of student reasoning in this area and of how this reasoning evolves with training in the domain. Thus, we have carried out a qualitative…

Heisterkamp, Kimberly; Talanquer, Vicente – Journal of Chemical Education, 2015
The central goal of this study was to characterize major patterns of reasoning exhibited by college chemistry students when analyzing and interpreting chemical data. Using a case study approach, we investigated how a representative student used chemical models to explain patterns in the data based on structure-property relationships. Our results…

Stains, Marilyne; Talanquer, Vicente – International Journal of Science Education, 2007
We applied a mixed-method research design to investigate the patterns of reasoning used by novice undergraduate chemistry students to classify chemical substances as elements, compounds, or mixtures based on their particulate representations. We were interested in the identification of the representational features that students use to build a…
