Chemistry courses remain a challenge for many undergraduate students. In particular, first-semester organic chemistry has been labeled as a gatekeeper with high attrition rates, especially among students of color. Our study examines a key factor related to conceptual understanding in science and predictive of course outcomes-knowledge structures.…

Problem solving is a highly valued skill in chemistry. Courses within this discipline place a substantial emphasis on problem-solving performance and tend to weigh such performance heavily in assessments of learning. Researchers have dedicated considerable effort investigating individual factors that influence problem-solving performance. The…

Science, Technology, Engineering, and Mathematics (STEM) education has become a key focus in the U.S. government's public education agenda. Many STEM degrees require the successful completion of undergraduate introductory organic chemistry (O-Chem), which is notorious for its difficulty and high attrition rate. Concept Maps (CM) have been used as…

This study sought to identify ethnically diverse students' study strategies in organic chemistry and their relationships to course outcomes. Study diaries, concept maps, and problem sets were used to assess study outcomes. Findings show that students engage in four commonly used reviewing-type strategies, regardless of ethnic group affiliation.…

In the first part of this article, the use of Generalizability (G) theory in examining the dependability of concept map assessment scores and designing a concept map assessment for a particular practical application is discussed. In the second part, the application of G theory is demonstrated by comparing the technical qualities of two frequently…

In the first part of this paper we discuss the feasibility of using Generalizability (G) Theory to examine the dependability of concept map assessments and to design a concept map assessment for a particular practical application. In the second part, we apply G theory to compare the technical qualities of two frequently used mapping techniques:…

The validity of connected understanding interpretation of three concept mapping techniques was studied, focusing on the correspondence between mapping-intended task demands, inferred cognitive activities, and scores obtained. The concurrent and retrospective verbalizations of subjects at different levels of competency as they performed the mapping…

Developed a framework for examining cognitive validity claims and used it to evaluate the validity of a "connected understanding" interpretation of three concept mapping techniques used by two teachers and six high school students. Results show that the three mapping techniques provide different pictures of student knowledge and suggest that…

Reports the results of a study that compared two concept-mapping techniques, one high-directed, "fill-in-the-map" and one low-directed, "construct-a-map-from-scratch". Examines whether: (1) skeleton map scores were sensitive to the sample; (2) the two types of skeleton maps were equivalent; and (3) the two mapping techniques provided similar…

As faculty, our goals for students are often tacit, hidden not only from students but from ourselves as well. We present a conceptual framework for considering teaching goals--what we want our students to achieve--that encourages us to think more broadly about what we mean by achieving in our knowledge domains. This framework includes declarative…

A concept map is a graph in which the nodes represent concepts, the lines between the nodes represent relations, and the labels on the lines represent the nature of the relations. Concept maps have been used to assess students' knowledge structures, especially in science education. Two concept mapping techniques, constructing a map and filling in…

A concept-map assessment consists of a task that elicits structured knowledge, a response format, and a scoring system. Variation in tasks, response formats, and scoring systems produce different mapping techniques that may elicit different knowledge representations, posing construct-interpretations challenges. This study examined two mapping…

We examine the equivalence of two construct-a-concept-map techniques: construct-a-map with created linking phrases (C), and construct-a-map with selected linking phrases (S). The former places few constraints on the respondent and has been considered the gold standard; the latter is cost and time efficient. Both their products and processes are…

One potential approach to the authentic assessment of what students know and can do in science is concept mapping. A concept map is a graph consisting of nodes representing concepts and labeled lines denoting the relation between a pair of nodes (concepts). The external concept map constructed by the student is interpreted as representing…
