This study was carried out to examine proportional reasoning problem solving processes of seventh grade students. This study was conducted with the explanatory sequential mixed method design. In this respect, firstly, quantitative data from 56 students were collected and analyzed. Then, qualitative data of the study was collected from six students…

This study investigates how players make ethical decisions in "Fable III," a video game, with consideration to avatar gender. Thirty males, 18 to 34 years old, were recruited; 20 were assigned to play "Fable III," with half assigned to play as a male avatar (Condition 1), and half assigned as a female avatar (Condition 2). Any ethical thinking…

Although test scores from similar tests in multiple choice and constructed response formats are highly correlated, equivalence in rankings may mask differences in substantive strategy use. The author used an experimental design and participant think-alouds to explore cognitive processes in mathematical problem solving among undergraduate examinees…

This study explored the effects of alternative forms of argumentation on undergraduates' physics solutions in introductory calculus-based physics. A two-phase concurrent mixed methods design was employed to investigate relationships between undergraduates' written argumentation abilities, conceptual quality of problem solutions, as well…

The present study explored how seventh graders develop their understanding of climate change issues. Particularly, I focused on identifying students' ways of reasoning in evaluating and generating arguments. I also investigated whether students reason differently about climate change issues depending on the relevance of the issues to their daily…
