Melanie Cooper was installed as the first Lappan-Phillips Professor of Science Education in the Department of Chemistry in the College of Natural Science in 2013. She has spearheaded the transformation of the department leading a multi-year effort to improve undergraduate STEM education.
The focus of our research is to develop evidence based approaches to teaching, learning and assessment. Our work involves a wide range of activities and methods including designing ways to assess both what students know and how they use their knowledge, developing curriculum materials and evaluating the effects of transformation efforts both within and across disciplines.
We want students to develop a deep understanding of core ideas they can build on and put to use, not just facts they can regurgitate. This is starting to happen for younger students and there’s no reason it should stop at 12th grade.
To design effective curricula we need to know what students bring to the table both in their prior knowledge and what they are able to do with that knowledge. We also must understand how and why students develop ideas that are not scientifically sound. For example we have shown that for many students, when they consider how the molecular level structure of a substance can be used to predict macroscopic properties, their ideas are often a loosely woven tapestry of concepts, facts and skills, rather than a useful framework of ideas.
Our approach to curriculum transformation uses a design based research cycle in which we identify what students should know and be able to do, design and implement a curriculum that would meet these goals, assess student achievement and use the results of the assessments to revise the curriculum and accompanying assessment materials. These assessments require students to construct (free form) structures, diagrams, and models, and to develop explanations for phenomena. Our formative assessment system, beSocratic, is designed to recognize and respond to student input.
Examples of this process are Chemistry, Life, the Universe and Everything (CLUE), an NSF supported general chemistry curriculum, and the current design project Organic Chemistry, Life, the Universe and Everything (OCLUE) (both developed in collaboration with Mike Klymkowsky, University of Colorado at Boulder).
Using this system we have evaluated how students in both traditional and CLUE curricula understand a range of chemical ideas and phenomena. For example we have shown that CLUE students are more likely to understand that intermolecular forces are interactions between small molecules (not within) as shown in the Sankey diagram below. We have also shown improvements in understanding structure property relationships, and understanding of acid base reactions.
