Alejandra Magana Wins Best-Poster Award
On March 5, the Purdue College of Education and the Graduate Students in Education Council sponsored the Second Annual Graduate Student Educational Research Symposium, a research symposium for graduate students in education-related degree programs from across the Purdue. Three best poster awards and cash prizes were given to:
"Taxonomy of Size and Scale"
"Possible Cognitive Impacts of Antieleptic Drugs and Their Implications on Educational Practice: A Narrative Synthesis"
"A Follow-up Meta-analysis of Word Problem Solving Interventions
Taxonomy of Size and Scale: Nanotechnology has become an increasingly important area in science and technology. However, one of its important underlying concepts, namely notions of size and scale, has been identified as one of the challenging concepts for middle school level students. In order to understand students' conceptions of size and scale, we have developed a taxonomy and have identified the cognitive processes behind them. This study presents the results of 170 students before and after instruction. The results suggest that instructional materials designed under the cognitive information processing perspective may serve as an adequate scaffold for conveying notions of size and scale.
