Schlessman notes that Johnson's article on role of theory in second language (L2) teachers' education opens a Pandora's box in attempting to determine what it means to have two forms of knowledge, conceptual and perceptual. Johnson argues that theory can transform practice only if teachers have varied opportunities to make sense of theory within…

Explores the intuitive understanding of biology that occurs in early childhood and discusses later cognitive changes that occur. Young children possess a vitalistic understanding (e.g. breathing brings power to the body) that becomes mechanistic (e.g. an understanding of the heart and lungs) as they mature. Includes statistical and tabular data.…

Fourth-year university students (n=12) in a secondary-science-education degree program in Singapore were interviewed after demonstrations of five familiar chemical reactions. The majority of interviewees used perceptually-dominated rather than conceptually-dominated thinking and were unable to use scientific concepts consistently across the five…

Argues that science students often perceive physical events, the nature of scientific knowledge, and the nature of learning processes in different ways from science teachers and scientists, and that science teachers need to account for these differences in planning their science teaching. Contains 40 references. (WRM)

Identifies the essential features of critical inquiry and shows how it differs from the critical procedures often recommended by educators. Explains the implications of the inquiry process for teaching criticism. Provides a model of critical-inquiry instruction by suggesting three basic instructional strategies for teachers and describing an…

Presents a theory of learning in science based on students deriving conceptual linkages among multiple models which represent physical phenomena at different levels of abstraction. Finds that high school students who were exposed to derivational links among three models for basic electricity performed better when solving both qualitative and…

Examines the extent and nature of Year 10 students' model-based reasoning in a laboratory investigation that considered the influence of six factors on electrical resistance. Finds that spontaneous use of the electron-drift model of metals in explanations increased over the duration of the task, but the explanations were restricted to mainly…

Questions whether self-assessment helps teachers develop new conceptual structures in the context of integrated science. Examined 22 inservice teachers with concept maps, interviews, and questionnaires while they used teaching materials for eight integrated topics in the German PING Project. Discusses the importance of using self-assessment to…

Attempts to find connections and bridges between social constructivism and Piagetian constructivism so that both may be enriched, to the benefit of science teaching. (Contains 95 references.) (Author/WRM)

Urges music educators to use activity-based instruction as opposed to more traditional methods. Provides two lesson plans for middle school students where they learn about musical instruments in an integrated science and music environment that promotes concept formation and the exploration of the role of culture in music-making. (CMK)

Thirty Native American children (mean age=10.3 years), 15 identified with fetal alcohol syndrome (FAS) and 15 controls, were asked to recall places and objects in a task previously shown to be sensitive to memory skills in individuals with and without mental retardation. Children with FAS demonstrated a spatial but not an object memory impairment.…

Used cases of democratic and non-democratic governmental systems and freedom of speech to investigate 6- to 11-year-olds' notions of political fairness and democracy. Found that political fairness concepts were applied at all ages to evaluate governmental systems and reject non-democratic alternatives. Older children were more likely than younger…

Investigates the hypothesis that preservice teachers specializing in science and mathematics will score significantly higher on spatial ability tests than other preservice teachers. Also investigates gender-related differences in spatial ability. Contains 26 references. (DDR)

Describes the professional development framework utilized in the Integrating Laboratory Instruction and Assessment (INLAB) project directed at changing teacher practice. The framework is based upon the establishment of an intellectual community of learners. (DDR)

Describes an innovation designed to capitalize on certain benefits of concept maps. Uses computer software with preservice teachers to enable them to construct concept maps that represent their own subject matter knowledge. Contains 21 references. (DDR)
