This paper urges special educators to be wary of borrowing fashionable rhetoric of postmodernism to justify constructivism in the reform of instruction and curriculum without disentangling accompanying constructs and values. There are higher stakes for special education, particularly in national curriculum and testing reform, that accompany…

Analyzes how practice in mathematics education might be reformed toward a professional practice. Argues that conventional school mathematics be replaced by a constructivist school mathematics based on children's use of their schemes of actions and operations in learning situations as illustrated through examples of the numerical schemes of…

Describes a theoretical frame for understanding cognitive development to outline the planning and performance of a unit on electrostatics. Analyzes a female student's learning process and the development of the complexity of her cognitive skills. (PR)

Interviewed 10 students in a secondary school teacher education program to determine the students' understandings of environment. Four conceptualizations of environment were portrayed: social, political, bio-physical, and inclusive. Four conceptualizations of human-nature relationships were described: connected, separate,…

Examines the impact of a specially designed in-service model on teacher understanding of selected science concepts. From an analysis of 42 teachers' concept maps, there was significant growth in the number of valid propositions expressed by teachers between the initial and final mappings in all topic groups.(PR)

Argues that by examining which concepts of a particular area of physics are fundamental and which are defined, teachers can choose concepts for investigation that progress logically and should minimize students' misconceptions and confusion. (Author)

Describes how Mexican-American language-minority students construct biology concept meanings based on extant linguistic skills. Provides an instructional activity that engages students in constructing meanings through mediational means. Contains 35 references. (DDR)

Reports on the application of technology in elementary and secondary education. The report is based on a review of the research literature and on written submissions and oral briefings from a number of academic and industrial researchers, practicing educators, software developers, and government agencies.

Examines changes in preservice elementary teachers' beliefs about teaching and learning mathematics and their ability to provide mathematics instruction that is based on children's thinking. Reports that, after participants were introduced to Cognitively Guided Instruction (CGI), significant changes in their beliefs and perceptions about…

Because traditional instruction ignores students' personal construction of mathematical meaning, mathematical thought development is not properly nurtured. Several issues must be addressed, including adults' ignorance of math- and student-learning processes, identification of math-education research specialists, the myth of coverage, testing…

Identifies and clarifies an interpretation of scientific discourse that can be used as a lens for viewing problems of teaching science. Discusses why reform visions for science education are reasonable, desirable, and yet problematic in lower track classrooms. Presents data to explain and characterize lower-track science-classroom discourse.…

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…

Describes the implementation and evaluation of a constructivist course for science teachers in which teachers are inducted into "critical constructivism" through their own action-research projects. Illustrates the induction process and professional development of one biology teacher of 13- to 15-year olds in Brazil. Contains 23…
