Reviews research of writing activities that help identify student misconceptions and serve as a vehicle for knowledge construction. (29 references) (MDH)

Discussed is how the concept of equivalence can relate various segments of a mathematics program and help students develop an appreciation of the unity of mathematics. Activities and examples of equivalence at all grade levels are included. (KR)

Reports results of procedures directed at isolating and identifying students' difficulties in comprehending the concepts involved in lessons about gas exchange and respiration. Indicates that pupils (n=137) had deficient understanding of prerequisite concepts and tended to operate at the concrete operational level, whereas the highly abstract…

A study with 45 British undergraduate and graduate science students investigated the usefulness of a semistructured workshop interview to identify students' concept difficulties in chemistry, their understanding of the use of analog models, and other science education issues. Implications for use of the workshop interview technique are considered.…

Discusses a variation on tiling that offers opportunities for the construction of the fundamental mathematical concept of constructing abstract units called "unitizing." Tiling integrates geometric and numerical settings to develop spatial sense and present mathematics as constructing patterns. (MDH)

Discusses and provides sample lessons of learning by discovery and weekly problem sets, which are presented as alternative methods for teaching college calculus. Both approaches stress conceptual understanding and guide the students to explore the ideas of calculus in small groups in a computer laboratory setting. (JJK)

Describes and illustrates the Monomial Sums Approach, a graphical learning strategy, facilitated by microcomputer capabilities that allow easy manipulation and exploration of graphical representations of polynomial functions. Reduces emphasis on memorized rules in favor of qualitative understanding of functional behavior, visualization of…

This study examined the representations that a 16-year-old student made using the flexible computer system, "Boxer," in learning the genetic code. Results indicated that programing made it easier to build and explore flexible and useful representations and encouraged interdisciplinary collaboration between mathematics and biology…

Asserts that promotion of classroom thinking generally is assumed to be the sole responsibility of the teacher. Suggests using a text that portrays students engaged in reasoning and other interventions to stimulate the growth of critical and creative thinking. (CFR)

Described is the Educational Leaders in Mathematics (ELM) Project, a four-stage inservice teacher program designed to stimulate teachers' development of a constructivist view of learning. The impact of the intervention was studied, and results indicated that teachers' beliefs were affected, producing changes in teaching strategies. (MDH)

Discusses concept books with regard to educational value, evaluative criteria, and relationship to child development. An annotated bibliography of 29 concept books appropriate for early childhood classrooms is included that lists books on colors, foods, occupations, money, senses, shapes, and time, and activities for integration in the content…

Focuses on the language used in mathematics instruction and the ways in which teachers assist students in constructing the formal language of mathematics. Strategies to help students connect vocabulary with mathematical concepts include using teacher modeling, writing, cooperative learning, and having students define words in their own language.…

Concept mapping was used to tap the conceptual disciplinary (science subject) knowledge and pedagogical knowledge of seven biology and six geography teachers with short or long teaching experience. Results indicate that knowledge in both areas is unsatisfactory, experience does not improve the knowledge, and teachers mastered disciplinary…

Videotaped interviews of 29 Australian students from grades 1-3 were analyzed to assess and compare the processing loads of mathematical representations and strategies used by teachers and children to learn the concept of place value. Results indicated that some representations and strategies impose an unnecessary processing load that can…

Twenty-three building and central office public school administrators identified internal and external system sources that they thought had influenced them to believe that effected school policy changes were or were not needed. A very large majority attributed major curriculum change influence to internal system sources. (SLD)
