Students need a strong understanding of how to represent chemical compounds in order to succeed in organic chemistry. This project set out to gain a better understanding of students' difficulties with symbolic representations, by identifying the specific errors associated with drawing wedge-dash structures. The focus was on how students…

Interactive simulations are entering mainstream science education. Their effects on cognition and learning are often framed by the legacy of information processing, which emphasized amodal problem solving and conceptual organization. In contrast, this paper reviews simulations from the vantage of research on perception and spatial learning,…

Noting that understanding how science students respond to anomalous data is essential to understanding knowledge acquisition in science classrooms, this paper presents a detailed analysis of the ways in which scientists and science students respond to anomalous data. The paper postulates seven distinct forms of response to anomalous data: ignoring…

Reported is a study of two instructional strategies: (1) the placement of key questions in text materials, and (2) the use of prescriptive feedback to direct students who missed text questions to appropriate remedial work. Learning that resulted from these two techniques was examined relative to achievement, time-on-task, and efficiency.…

Presented is an analysis of a concept teaching technique that was developed according to a theoretical perspective which emphasizes the importance of a student's existing knowledge in influencing that person's subsequent learning. Significant differences between an experimental group which was exposed to this instructional strategy, and the…

Described is how teachers can use the Concept Structuring Analysis Technique (ConSAT) as a diagnostic, learning, and assessment task in teaching science. In essence, ConSAT assists students in organizing concepts on paper so that they may link what they already know to what they have to learn. The technique thus applies the philosophical notion of…

Experienced Physicists solve simple textbook problems differently from beginning students. This paper describes these differences using a computer-implemented model that "learns." The research is set in the the context of modern computer-processing psychology, and is related to other work relevant to help people know and learn…

Reports on students' study and drawing of five electronic circuit diagrams. Concludes that the success of the students depended upon the amount of detail in the instructional diagrams. (RT)
