Judgments of similarities between numbers were solicited from kindergarten, third-grade, sixth-grade, and adult subjects. Results suggested children become sensitive to an expanding set of numerical relations during the period from kindergarten through sixth grade. Results of a second study suggested that the number similarity judgments of…

This annotated bibliography contains 12 references on computers in elementary school mathematics. Topics include developing mathematical concepts with microcomputer activities, teaching mathematics with computers in primary grades, microcomputers and problem solving, review for grade 1 software, early learning of logic and geometry using…

A Biological Sciences Curriculum Study (BSCS) inquiry approach for university general biology laboratory was tested against a well-established commercial program judged to be highly directive. The BSCS was found to be more effective in learning biology laboratory concepts than the commercial program as measured by a laboratory concepts test.…

Investigated students' (N=43) conceptions of what happens when water boils, evaporates, and condenses, and when ice melts. Results obtained from clinical interviews indicate that childrens' conceptions are quite different from those of scientists and that their ideas can sometimes be influences in unintended ways during instruction. Implications…

A concept development program to prepare first and second grade blind children for future mobility training was established at the Illinois Braille and Sight Saving School in Jacksonville, Illinois. (Author)

Presents arguments in favor of setting behavioral objectives for the social studies. A discussion of criticisms that have been made of the behavioral objective approach to curriculum development is presented. The author concludes that it is impossible to determine the success of a program without specific behavioral objectives. (Author/DB)

This research offers empirical evidence of the importance of supplying diverse symbolic representations in order to support concept development in mathematics. Graphical representation can be a helpful symbolic tool for concept development in the conceptual field of additive structures. Nevertheless, this symbolic tool has specific difficulties…

The paper reports on a case study from a teaching experiment on the construction of meaning of integral at secondary school level, starting from the cognitive root of area. In the considered activity, students are faced with some graphs of functions and are asked to work in group to trace the corresponding integral functions. The analysis…

Advocates of a multicultural curriculum in the public schools argue that including the heritage and cultures of the many cultural and ethnic groups in our society will result in a better educated citizenry with a better understanding of the broader society of the United States. To achieve this goal it is important that students investigate ways of…

The undergraduate curriculum in differential equations has undergone important changes in favor of the visual and numerical aspects of the course primarily because of recent technological advances. Yet, research findings that have analyzed students' thinking and understanding in a reformed setting are still lacking. This paper discusses an ongoing…

Teaching Adult Students Mathematical Investigation is based on the continuing research work carried out for the last ten years of teaching on the Foundation Course in Mathematics at Goldsmiths, University of London. Teaching Mathematical Investigation to adult students is a very challenging and often rewarding experience for adult educators as…

This paper considers what physics can offer students, both as physics majors and in other sciences. The recent increases in the technological character of the workplace appear likely to continue, leading to increasing numbers of individuals who should learn something about science. For many of these people, understanding the character of science,…

Scientific language is not simply for recording facts but it is also an instrument of thought. It has a central role in not only developing a sense of social identity for members of the scientific community and students in the classroom but also in inculcating views on the nature of science and reality itself. Physicists have created a language in…

The concept of function is central in mathematics and grows in importance as one progresses in depth and breadth of understanding mathematics. Results from national assessment progress reports indicate that the majority of students do not comprehend the concepts of function and graphing. Technology has the potential to improve the understanding of…

The purpose of this study is to describe the assessment environment in constructivist-oriented science, technology, and society (STS) classrooms. Data were gathered from in-depth interviews and subjected to a constant comparative analysis associated with a grounded theory model. Three themes emerged from the analysis: (1) a description of the…
