When characterizing students' item-solving strategies, methods such as interviews and think-aloud protocols are often used. However, these measures provide limited information about sub-or preconscious signals and cognitive processes that also affect students' item-solving strategies and abilities. A growing number of researchers in chemical…

The Spring 2020 semester will be marked in our history as one of the most challenging semesters for higher education, although through the adversity, we were presented with opportunities for classroom innovation. A reflective account of the teaching insights gained from implementing a COVID-19 miniunit and utilizing remote oral examinations is…

Nuclear magnetic resonance spectroscopy (NMR) plays a key role in introductory organic chemistry, spanning theory, concepts, and experimentation. Therefore, it is imperative that the instruction methods for NMR are both efficient and effective. By utilizing eye tracking equipment, the researchers were able to monitor how second-semester organic…

Studies in cognitive science have verified that working memory (where the brain solves problems) can manipulate nearly all elements of knowledge that can be recalled automatically from long-term memory, but only a few elements that have not previously been well memorized. Research in reading comprehension has found that "lecture notes with…

Multiple-choice questions are an important part of large-scale summative assessments, such as the advanced placement (AP) chemistry exam. However, past AP chemistry exam items often lacked the ability to test conceptual understanding and higher-order cognitive skills. The redesigned AP chemistry exam shows a distinctive shift in item types toward…

Mental-rotation ability modestly predicts chemistry achievement. As such, sex differences in mental-rotation ability have been implicated as a causal factor that can explain sex differences in chemistry achievement and degree attainment. Although there is a correlation between mental-rotation ability and chemistry achievement, laboratory and field…

Making decisions about the production and use of chemical substances is of central importance in many fields. In this study, a research team comprising teachers and educational researchers collaborated in collecting and analyzing cognitive interviews with students from 8th grade through first-year university general chemistry in an effort to map…

In this study, we seek to understand the beliefs that chemistry faculty hold when grading student solutions in problem solving situations. We are particularly interested in examining whether a conflict exists between the chemistry faculty beliefs and the score they assign to students' solutions. The three categorical values identified in a similar…

This study, part of a series investigating students' use of online tools to assess problem solving, uses eye-tracking hardware and software to explore the effect of problem difficulty and cognitive processes when students solve gas law word problems. Eye movements are indices of cognition; eye-tracking data typically include the location,…

Organic Chemistry is recognized as a course that presents many difficulties and conceptual challenges for students. To combat the high failure rates and poor student attitudes associated with this challenging course, we implemented a "flipped" model for the first-semester, large-enrollment, Organic Chemistry course. In this flipped…

Undergraduate students were asked to complete gas law questions using a Web-based tool as a first step in our understanding of the role of cognitive load in chemistry word questions and in helping us assess student problem-solving. Each question contained five different complexity factors, which were randomly assigned by the tool so that a…

As part of a campus-wide, externally funded project to increase performance in, enthusiasm for, and retention within STEM disciplines, we developed an interdisciplinary, team-taught first-year seminar course. The construction and delivery of this course was designed to show the relevance of selected general chemistry topics such as matter and…

Explains why it is important for chemistry educators to know about metacognition, provides some examples to illustrate main points, and discusses some instructional tools that have been employed to promote metacognition in introductory science courses. (Contains over 50 references.) (WRM)

Describes three types of chemical content, learning strategies for each type, and methods of teaching students to use the appropriate strategies. Provides suggestions for improving students' ability to learn. (CW)

Discusses some central ideas emerging from a systematic approach to teaching scientific problem-solving skills. Areas considered include: insights derived from naturalistic studies; effective problem-solving methods; problem-solving procedures; characteristics of the knowledge base (focusing on functional conceptual building blocks, knowledge…
