Environmental knowledge and awareness of individuals affect their attitudes and behavior toward the environment. In this regard, it is essential to specify how environmental issues are interpreted in individuals' cognitive structures. This study aims to investigate preservice science teachers' cognitive structures on environmental issues. The…

In this study, we investigated whether concept maps were used as often and as effectively in elementary science and technology classrooms as recommended by the National Ministry of Education (MEB) in the new curricula in Turkey. In the new elementary science and technology curricula, the MEB provides a general concept map for each unit. We used…

The development of rich, reliable, and robust measures of the composition, structure, and stability of student thinking about core scientific ideas (such as natural selection) remains a complex challenge facing science educators. In their recent article (Nehm & Schonfeld 2008), the authors explored the strengths, weaknesses, and insights provided…

There is no agreement about the robustness of intuitive representations of the circulatory system and their susceptibility to change by instruction. In this paper, we analyse to what extent students with varying degrees of biology instruction and different ages (High School Health Science and Social Science students and first and final year…

Propositions expressed by students during interviews prior to and after audiovisual instruction served as the basis for Concept Propositional Analysis (CPA) to assess cognitive structure. CPAs for two students are reported and aspects of Ausubelian principles are discussed. The method showed that new learning can be linked to previous…

Introduces the ideas of "distal" knowledge of the nature of science and "proximal" knowledge of the nature of science. Suggests that viewing these two kinds of knowledge structures within modern information processing frameworks that delineate roles of epistemological and metacognitive knowledge in learning should guide future research. (Contains…

Knowledge elicitation through programming was studied to determine students' intuitive ideas about motion. The subjects, 17-year-old sixth-form science students and 14-year-old third-form students, were asked to write expert systems programs about motion; and their interactions with their own knowledge were observed. The 17-year-old students had…

Describes a study that investigated the relationship and development of fifth-grade students' conceptual ecologies of heat. Contends that relying on a single mode of assessing students' learning can lead to a restricted view of what they truly know. (WRM)

Examines aspects of 10-year-old children's conceptions of understanding. Analyzes to what extent they (1) recognize understanding as a cohesive whole, (2) know when a descriptive understanding versus a causal understanding is expected, and (3) can distinguish between the types of causal understanding in science and history. Includes references and…

Argues that individual teacher's conceptions of disciplinary knowledge are reflected in the curricula but that institutional factors also influence the curriculum presented to students. Discusses constructivist epistemology and employs qualitative research to interpret teachers' conceptions in a case study of three biology teachers. Suggests…

Fifty-three elementary school children were tested on Incidental Science Knowledge, i.e., knowledge acquired by chance outside school, and the results obtained were correlated with intellectual development and cognitive style as measured by interviews and group testing, respectively. Indicates that cognitive style and misconception play a…

Scientific and everyday knowledge domains are compared so as to reveal the distinctive differences between their goals and the cognitive processes used to attain them. The main goals, working goals, learning difficulties, knowledge structure, concept specification, knowledge organization, role of school science, program-solving instruction, formal…

Explores high school students' and preservice teachers' knowledge of light, vision, and related topics before and after commonly practiced instruction. Suggests a hierarchical structure to represent the collective conceptual knowledge of students and teachers in terms of facets and schemes of knowledge. Makes suggestions for designing instruction…

Discusses Vee mapping, a technique to assist students in categorizing the relationship between the conceptual and procedural aspects of science. Presents a study to investigate elementary education majors' (n=27) use of the Vee heuristic and concept mapping for the construction of knowledge; attitudes toward learning science in collaborative…

An overview is presented of the epistemology of the three types of constructivism. Criticized is another interpretation of constructivism; it is stated that this interpretation is trivial, cognitively abridged, and disrespectful of students' capacities, creativity, and imagination. Constructivism has to go beyond saying that knowledge is…
