Investigates whether and how collaborative learning at the computer fosters conceptual change. Employs a suite of computer-simulation programs developed to confront students' alternative conceptions in mechanics. Contains 46 references. (DDR)

Two elementary teachers teamed up to help colleagues develop classroom strategies to use with children suffering from attention deficit disorders. From a pilot test conducted with other volunteer teachers, they developed a systematic process featuring teacher-request consultation forms, strategy searches, action plans, implementation, and followup…

Parrot math (memorization) seeks to control children through external rewards and punishments, rather than harness their intelligence and curiosity. Recent standardized test results document parrot math's failure. Activities-based approaches, supported by a constructivist philosophy (involving classifying, inferring, generalizing, and…

Third International Mathematics and Science Study results show that high-scoring states and schools do not need standards; low scorers have too many other pressing problems to utilize standards. Recent studies indicate that the proportion of college students requiring remedial courses has been exaggerated by critics. (MLH)

Randomly selected high school students (n=13) who studied an ecology unit were interviewed, and narrative data analyzed for changes in knowledge schema. Data support the current theory that the amount and quality of prior knowledge substantially influence gains in new knowledge and are closely linked to a capacity to apply higher-order cognitive…

Explores changes in students' (n=250) thinking about basic chemical ideas during a context-based curricular approach. Suggests that 16- to 18-year-old students enter chemistry courses with a wide range of misunderstandings about chemical reactions, but understanding improves steadily as the course progresses. Concludes that even misunderstandings…

Presents results of a pretest/posttest measure for assessing scientific literacy that was given to a general biology class for nonmajors. Test questions are listed and include items covering popular biology-related misconceptions. (WRM)

Investigates the effects of both computer animations of microscopic chemical processes occurring in a galvanic cell and conceptual-change instruction based on chemical demonstrations on students' conceptions of current flow in electrolyte solutions. Finds that conceptual change instruction was effective at dispelling student misconceptions but…

Analyzes a teaching episode to determine how a conflict is perceived and overcome by students as a result of verbal interaction between the teacher and the students. Discusses the particulate nature of matter with students aged 15-16 after observing a glass of water containing a rock and an ice cube. (Contains 25 references.) (Author/YDS)

The thinking process does not always start with problem situations that produce cognitive conflict, and the confrontation of students' misconceptions is not always successful as a teaching approach. Contends that curiosity and mystery appear to excite human thinking and could therefore be considered to be the starting point in science teaching and…

Presents the results of a cross-age study of 7- to 15-year-old children on their thinking about vertebrate and invertebrate animals. Suggests experiences that could be included in the school science curriculum and argues for more classroom work relating structure with function in order to address students' conceptual difficulties. (Contains 18…

Reviews and assesses the effectiveness of the attempts undertaken to improve prospective and practicing science teachers' conceptions of the nature of science (NOS). Categorizes reviews as implicit or explicit. Indicates that the explicit approach was more effective in enhancing teachers' views. Assumes that developing an understanding of NOS is…

Discusses the five major concerns that govern a school nurse's thinking in managing head louse infestations, including dispelling misconceptions about head lice; ensuring that infestations are not missed; ensuring that parents understand instructions for effective treatment; educating the community about the correct use of pediculicides; and…

Discusses how biologists use evolutionary theory and provides examples of how evolutionary biologists test hypotheses on specific modes of selection and evolution. Presents an example of the successful predictive power of one evolutionary hypothesis. Contains 38 references. (DDR)

Today's teachers are unprepared to meet increasingly complex assessment challenges. The poor state of assessment literacy arises from naive assumptions about standardized testing and student motivation, fear of being held accountable for student achievement, parents' nostalgic views of testing, and confusion over achievement expectations for high…
