Reports a study (n=27) concerning the knowledge about image formation exhibited by students following instruction in geometrical optics in an activity-based college physics course for prospective elementary teachers. Student diagrams and verbal comments indicate their knowledge can be described as an intermediate state: a hybridization of…

Presents anecdotes, discussion, and definitions of the terms natural, conflicting, and alien as they relate to the teaching and learning of mathematics. (MKR)

Examined preschoolers', first-graders', and third-graders' responses to questions in which one authority (mother or teacher) permitted a moral or conventional act to occur across contexts and the other authority prohibited the act from occurring across contexts. Found that children's evaluations were a function of the authorities' status, the…

Reviews the current literature concerning prior knowledge in an attempt to clarify problems with the terminology. Identifies the three main problems: lack of definition or vagueness, nominal versus real definitions, and different names/same constructs or same name/different constructs. Includes a conceptual map of prior knowledge terminology. (MJP)

Examines the relationship of grade level to children's ability to make musical discriminations when elements are presented simultaneously. Utilized a brief instructional period, listening tests, and singing tasks. Results indicated significant differences between grade level, types of discrimination, and musical interactions. Includes statistical…

Papers by graduate students, and occasionally papers from their mentors which establish a context for the student papers, are organized by sponsoring University. Student papers presented are: (1) "The Relationship of Amount of Experience in Art to Visual Perception and Picture Memory" (Scott Wiley); (2) "In Pursuit of the Idea that…

Mapping Our City is a two-year project in which middle school teachers and students in Boston explore the uses of Geographic Information Systems (GIS) in project-based science, environmental education, and geography. The project is funded by the National Science Foundation and is being field tested in three Boston middle school science classrooms.…

"Talking Science" does not mean simply talking about science; it means doing science through the medium of language. This is a book about communication, scientific, and technical education. Chapters 1 and 2 introduce the specific themes and methods of the book. Each analyzes a brief classroom episode, looking from two different points of view at…

The distinction between the participant and spectator functions of language are used to describe the teaching skills of a fourth grade teacher during a unit of instruction. This study documented the science instruction of a teacher who 20 years ago majored in teaching reading. In recent years she has taken steps to develop skill and knowledge in…

This paper begins by exploring some general issues associated with the idea of progression in education in general and in science education in particular. These are then related to the particular domain of interest of the Procedural and Conceptual Knowledge in Science (PACKS) Project, which is concerned with the responses of children, aged 9 to…

This proceedings covers the domain and content areas of learning and learners; curriculum and materials; instruction (including computer-assisted instruction); assessment and evaluation; history and philosophy of science; teacher preparation and professional development; and related areas of interest including environmental, special, health,…

This study describes the steps taken to measure the integrity of an intermediate concept measure and test the assessment strategy of a well-validated dental ethics curriculum. Because this curriculum, which had been in place for 15 years, had consistently been shown to influence moral judgment, it was posited that a cross-sectional comparison…
