This study compared the development (at 40 months) of 40 deaf and hard-of-hearing infants whose hearing loss was identified either before 6 months or after 18 months. Infants whose hearing loss was identified earlier scored significantly on tests of expressive language and comprehension/concepts. Results support early hearing screening for…

Illustrates the difficulty in trying to establish clearly defined categories between art forms. Addresses the problem through discussions of three artists: Malcah Zeldis, Mabel Burkholder, and Keith Haring. Suggests that a travel metaphor grants people a flexible and historically-oriented way to speak about artwork and art categories. (CMK)

Reports on the effects of constructivist versus traditional teaching approaches on university students' learning about osmosis and diffusion. Students understood diffusion and osmosis more deeply in the constructivist-informed classroom, which used small discussion groups rather than traditional large lecture groups. Suggests ways to improve…

Reports the existence of patterns of reasoning that are common to students' conceptions in different areas of mechanics. Finds that the common frameworks between different ideas have a generality level that lies between Piaget's stage theory and the approach of alternative conceptions. Contains 30 references.

Beginning secondary students find it easier to express their understanding of scientific evidence verbally rather than in writing. Concludes that much work can be done to improve the critical nature of the dialog pupils enter into in their written work, thus making their level of procedural understanding more clear. Contains 27 references.…

Young pupils find collaborative learning hard to sustain, even though it is recommended by developmental psychology and classroom intervention theories. Investigates the effect of two role attribution strategies on communication in peer groups of different gender composition in 8th grade science classes. Confirms the effectiveness of social role…

Concludes that the children had good prior awareness of some behaviors that save energy, but their reasons for thinking this were based largely on everyday intuitive ideas that involved…

Describes the MAOF physics education program which is designed to relate large parts of mechanics and electromagnetism to each other via the key concepts of field and potential, while at the same time treat students' conceptual difficulties. Finds that students who studied with the MAOF program significantly improved their physics knowledge…

Illustrates how the five cognitive levels--somatic, mythic, romantic, philosophic, and ironic--can be used to guide teaching and learning activities appropriate for engineering students. Uses the example of the concept of energy to demonstrate how educators might appeal to each mode of thinking for understanding a particular concept. (Contains 11…

Examines student conceptions of their experiences with science, describes the variety of those conceptions over the years of schooling, and investigates patterns across those years.

Explains the development of an interdisciplinary unit in which students learn basic chemistry and laboratory techniques while practicing English, mathematics, art, social studies, and leadership skills. Includes details about lab activities, assessment strategies, and science extensions. (DDR)

Advocates involving parents and family in science learning through photography. Students and their families are challenged to gather still or moving images of living or nonliving things actively engaged in using energy within their neighborhoods. Everyone learns more science through sharing information in discussion. In the process, teamwork,…

Examines the relative importance of teaching and scholarship in academia.
