Explores both the qualitative and quantitative dimensions of pupils' ideas related to conservation during state changes of water. Analysis of questionnaire data indicates that qualitative understanding precedes quantitative. Contains 18 references. (DDR)

Describes a study that explores the instructional influence of presenting pictures at the molecular level when introducing chemistry concepts and solving chemistry problems. Explores the effect of the pictures on students' conceptions and problem-solving abilities. Contains 59 references. (DDR)

Lends support to the idea that the quality of the cases used in problem-based learning affects the nature of student learning in this context. Outlines seven principles adapted from research on learning and cognition that can help guide case design. Contains 22 references. (DDR)

Two studies examined schematic information processing as a function of attractiveness stereotyping among 3- to 7- year-olds. Found that children made more errors identifying female characters with stereotype-inconsistent traits but either did just the opposite with male characters or had no difference in errors with male characters. Findings pose…

Recent contributions from theory, research, and practice in second-language instruction are discussed in relation to mathematics education. Three methods of teaching and learning second languages are described--"Delayed Oral Production," the "Silent Way," and the "Counseling Learning/Community Language Learning." (KR)

Discussed are preservice elementary teachers' misconceptions and inconsistent beliefs about multiplication and division with decimals. Sources of inconsistencies and recommendations for overcoming inconsistencies are included. (KR)

Discussed is the philosophy of the educational purpose of science education, the science involved, and the relationships of students and learning and students and content. A list of 14 references is included. (CW)

Used are test and interview data to extract evidence as to what level tenth graders have coordinated the worlds of arithmetic and algebra and can move freely between them. More dissociation is shown than was expected. (Author/MVL)

Reports on the assessment of student thinking in the area of commitment to the laws of conservation of matter and energy during a study of conceptual change among introductory chemistry students. States four conditions upon which strategies for conceptual change are based. (RT)

States that students have misconceptions about the principles of mechanics internationally providing examples and two problems. Describes Nachtigall's program to train teachers and reports its application to classroom teaching. (YP)

Children's magical explanations and beliefs were investigated in two studies. Found that many four-year olds view magic as a plausible mechanism, yet reserve magical explanations for certain real world events that violate their causal expectations. Parents and culture at large may at first actively support magical beliefs whereas peers and schools…

Proposes a theory for organizing information and activities in educational hypermedia systems and evaluates theory effectiveness based on implementation of a multimedia learning environment. Results suggest that self-paced interactive learning environments, multimedia information access, and constructive activities organized into cognitive media…

Challenges the widely endorsed practice of activating relevant knowledge prior to reading. Outlines a perspectival (perspective-relative) view of reading and suggests that this view provides a means to make coherent sense of interpretations. Concludes that having specific knowledge is not the main desideratum in interpreting texts--the main…

The importance of instructing gifted students in correlational reasoning is emphasized, with attention to what the skill involves and why it is difficult to learn; effective teaching strategies; and successful programs in whole-class, cooperative-learning, and computer formats. Implications in programming for gifted students are discussed. (SW)

The article reflects on using case method teaching in preservice teacher education, emphasizing situated problems of practice about which preservice teachers reflect by using tools of analysis, theoretical principles, professional wisdom, and autobiographical knowledge. The importance of conceptual, pedagogical, cognitive, and social structures…
