Describes and evaluates an attempt to teach about Brownian motion and to simultaneously draw out lessons about the nature of science. Outlines the learning tasks, summarizes and analyzes student responses from a questionnaire. (DDR)

Presents an activity devised as a method of introducing periodic functions that can enable students to gain a deeper understanding of the concept of function. Employs a calculator-based laboratory, a light sensing probe, and an appropriate calculator. Calculator programs and sample data are included. (DDR)

Investigated mothers' instructional strategies during concept-learning tasks, and the effect of this interaction on subsequent child performance. Found that interaction with mothers influenced children's posttest performance positively; more assistance was provided to three-year-olds than to five-year-olds and more on difficult than on easy tasks;…

Discusses what constitutes higher education standards and suggests that the standards debate should focus on defining educational goals and examining the consequences of implementing them. Some standards characteristics are examined, including specific, publicized, rigorous, high-stakes, inclusive, and measurable standards. Standards in relation…

Describes an activity that demonstrates among the following: diffusion; cohesion and adhesion; properties of surface tension which include wicking, hydrophilic, and hydrophobic molecular behaviors; and break up of fat clusters by liquid dishwashing detergent. (DDR)

Describes a study of third-grade students (N=38) that investigates the development of linear measurement concepts. Three levels of strategies were identified: visual guessing, hash marks, and no physical partitioning. Students who connected numeric and spatial representations proved to be the better problem solvers. Contains 22 reference. (DDR)

Examines how issues related to the implementation of innovations in the foreign language classroom relate to the contemporary education scene in the United Kingdom. The article argues that those whose mission is to effect substantial change in practice must consider how teachers and pupils learn and how teachers can be persuaded to view their…

Examines the essential characteristics of engineering teachers' pedagogical content knowledge by studying teachers' conceptions of their students' ideas of moment. Finds that although teachers originally appeared to be familiar with their students' conceptions, they were rather astonished by the general pattern of student thinking. (Author/SOE)

Details a study of students' text usage that used observations and interviews. Concludes that retrieval strategies are not transferred to learning from texts during science lessons. (Contains 41 references.) (DDR)

Discusses underlying mental processes for understanding volume measurement. Presents an instructional activity that promotes students' structuring of three-dimensional arrays of cubes and the electronic version of the "How Many Cubes?" activities. Includes student activity sheets. (KHR)

Contrasts student achievement using commercial curricula (CC) for initial fraction learning with that of using the Rational Number Project (RNP) fraction curriculum. Indicates that students using RNP materials had statistically higher mean scores on concepts, order, transfer, and estimation. Interview data showed differences in the quality of…

Investigates high-achieving fifth-grade students' achievement gains and conceptual reorganization on convection. Features an instructional sequence of three dyadic inquiry investigations related to convection currents as well as pre- and post-assessment consisting of a multiple-choice test, a card sorting task, construction of a concept map, and…

Discusses whether linguistics can meet the challenge of accounting to the general public for the practices and beliefs of lawyers and other professionals. The article emphasizes that members of the professions, such as lawyers, doctors, and psychiatrists, are judged by their interaction with processes having real world outcomes, e.g., trials and…

Examines the means by which trade mark law establishes determinacy of form.
