Chemistry students encounter a variety of terms, definitions, and classification schemes that many instructors expect students to memorize and be able to use. This research investigated students' descriptions of ionic and covalent bonding beyond definitions in order to explore students' knowledge about chemical bonding. Using Johnstone's Multiple…

This study explores what students understand about enzyme-substrate interactions, using multiple representations of the phenomenon. In this paper we describe our use of the 3 Phase-Single Interview Technique with multiple representations to generate cognitive dissonance within students in order to uncover misconceptions of enzyme-substrate…

The Assimilation Theory of Ausubel and Novak has typically been used in the research literature to describe two extremes to learning chemistry: meaningful learning "versus" rote memorization. It is unlikely, however, that such discrete categories of learning exist. Rote and meaningful learning, rather, are endpoints along a continuum of learning.…

In this quantitative study, a shortened version of the Attitude toward the Subject of Chemistry Inventory (ASCI) created by Bauer (2008) was used to identify the chemistry attitudes of two populations of general chemistry students at two universities. The ASCIv2 contained just two factors from the original instrument. These factors measured…

The role of assessment in the chemistry classroom is ultimately tied to the nature of the assessments available for use. Because they provide data that can inform decisions about curricular changes, or new pedagogies, the incorporation of new assessment strategies can play an important role in how educational and curriculum reform is carried out.…

This paper describes an expanded framework to aid chemical educators in constructing exams for their courses. The framework has three primary levels: definition, algorithmic, and conceptual. These primary levels have often been used in chemical education research to analyze and describe exam questions, but in this study the definition,…

We have investigated student difficulties with the learning of organic chemistry. Using Perry's Model of Intellectual Development as a framework revealed that organic chemistry students who function as dualistic thinkers struggle with the complexity of the subject matter. Understanding substitution/elimination reactions and multi-step syntheses is…

We have investigated chemistry faculty's cognitive expectations about learning chemistry and their influence upon the construction of exam questions in a general chemistry curriculum. Faculty cognitive expectations for learning chemistry were measured using QUIMX. Learning objectives and exam questions for a year-long general chemistry sequence…

At Miami University, the attrition rate in the year-long organic chemistry sequence for pre-medical majors typically ranges from 30-50%. To decrease attrition, the Department of Chemistry and Biochemistry developed an innovative, spiral curriculum. Unlike a traditional organic chemistry course that moves sequentially through the material, the…
