Considered are two commonly used techniques, the interview and word association techniques. Highlighted is a third technique called the repertory grid. This third technique can be used to interpret students' knowledge based on an explicit, psychological theory of human behavior. (Author/CW)

Outlines a cognitive model of visitors based on the concept of mindfulness/mindlessness. Presents an analysis of data on visitors to forestry centers in the United Kingdom. Results support the mindfulness approach as an appropriate cognitive model of visitors. (Author/CW)

Identifies the types of questions that students ask during science learning. Explicates the role of students' questions in the knowledge construction process, particularly in educational discourse. Investigates the relationship between students' questions and approaches to learning and discusses some emergent issues related to student questioning.…

Describes a study that used the ordered-tree technique to investigate knowledge change across the first semester of a college course in organic chemistry. Finds that over the course of the semester, students' knowledge trees became more similar to those of their professors. Discusses possible assessment uses for the ordered-tree technique.…

Describes the use of brain models to connect the microscopic level accessible by molecular and cellular techniques with the systems level accessible by the study of behavior. Discusses classes of brain models, and specific examples of such models. Evaluates the strengths and weaknesses of using brain modelling to understand human brain function.…

Describes a novel modeling and simulation package and assesses its impact on students' understanding of chemistry. Connected Chemistry was implemented inside the NetLogo modeling environment. Using Connected Chemistry, students employed problem -solving techniques characterized by stronger attempts at conceptual understanding and logical…

Presented are four research articles and staff development activities. Included are: an activity used to stimulate discussion of the issue of balanced science; a constructivist approach to teaching electric circuits; a science grading scheme; and a discussion of priorities in science education. (CW)

Discusses theories of how children represent the environment in their memory with reference to recent empirical evidence. States that children are more competent at recalling a route than has been assumed previously and that there are age-related differences in children's ability to select landmarks along a route. (Author/CW)

Research on propositional reasoning is summarized. Retrieval of facts and concepts, linkages, short-term memory limitations, and the processing advantages are discussed. Suggestions for maximizing teaching are presented. (CW)

Recent research in cognitive science and science education suggests that science-naive individuals have an understanding of the natural world based on their interpretation of everyday experience. This can make the process of conceptual change difficult. This paper presents ideas related to the acquisition of knowledge in astronomy. A theoretical…

Explores the rationale behind the importance of teaching young secondary school students how to look for correlation patterns. Describes two lessons that show how pupils can experience zero, positive, and negative correlation patterns between variables. Indicates the possible success of the Cognitive Acceleration through Science Education project.…

Describes a multiple-choice instrument that reliably and validly diagnoses secondary students' understanding of photosynthesis and respiration in plants. Highlights the consistency of students' misconceptions across secondary levels and indicates a high percentage of students have misconceptions regarding plant physiology. (CW)

Proposes an approach to school laboratory experiences which leads to gradual acquisition of inquiry skills based on the idea of advance organizers. Presents a design which is context familiar and can serve as an introduction to scientific inquiry. Discusses student achievement, and teacher and student attitudes. (CW)

Reports on a study to test the validity of the assumption that a teacher's conception of the nature of science directly influences his/her classroom behavior. Recommends a redirection in science education to promote more adequate conceptions of the nature of science in secondary schools. (TW)

Higher order thinking skills are inevitably developed or exercised relative to some discipline. The discipline may be formal or informal, may or may not be represented in a school curriculum, or relate to a wide variety of domains. Moreover, the development or exercise of thinking skills may take place at differing levels of generality. This paper…
