A model for learning mathematics is proposed which involves the components of using, discriminating, generalizing, and synthesizing. The ways pupils use Logo programs as tools within their projects and how the nature of their programming tools become more explicitly understood and generalized are discussed. (RH)

In this study, relationships were examined among three aspects of the implementation of complex instruction, an innovative approach to teaching in heterogeneous classrooms. These three aspects were: (1) teachers' use of the complex instruction strategies in the classroom; (2) systematic and comprehensive feedback received by teachers from the…

This study aimed to verify the efficacy of a strategy for science learning acquisition based on contextual, metacognitive and socio-cultural perspectives, strongly linked to the paradigm of conceptual change. The teaching model we adopted is based on co-operation for the realization of scientific experiences, and included direct observation, pair…

This study investigated the effect of three specific hands-on teaching strategies on the attainment and alteration of preservice elementary teachers' conceptions about earth-sun-moon relationships. The subjects (n=76) were enrolled in an elementary school science methods course. The descriptive nature of this study explored: (1) the effect of two…

Examples from related case studies illustrate possible consequences of a social constructivist approach to learning and teaching mathematics. Discusses student tasks that promote flexibility in mathematizing subject matter; constructive versus Euclidean geometry approaches; working with real-life mathematics problems; and product versus process…

An analysis of a 10-minute episode in which 7-year-old students (n=3) engage in collaborative small group activity is presented to explore the relationship between individual learning and group development. Students learned as they interactively constituted situations for justification or validation, yielding an institutionalized solution method.…

Describes journal writing as an element of multimodal teaching. Discusses how students utilize journal writing that includes pictures, numbers, symbols, and manipulatives to help understand mathematical concepts. Provides a form to evaluate students' portfolio writing and examples of students' evaluated work. (Contains 12 references.) (MDH)
