Many current generativist theorists suggest that young children possess the grammatical principles of inversion required for question formation but make errors because they find it difficult to learn language-specific rules about how inversion applies. The present study analyzed longitudinal spontaneous sampled data from twelve 2-3-year-old…

The Model Science Lab, a constructivist approach to teaching, strengthens urban science teachers' teaching practice. The retention rate of Houston science teachers who took part in the program was found to be very high and the cost of the Model Science Lab has proven less expensive per student than most other professional development options.

In Flanders, 2 classes per school were selected to participate in TIMSS. Therefore, a multilevel model with an intermediate level could be implemented. The data collection was extended with additional questionnaires and an intelligence test. The empty model revealed that 57% of the variance of mathematics scores was situated at the student level,…

In recent years, career development and career counseling have increasingly been informed by concepts emanating from the constructivist worldview. For example, the Systems Theory Framework (STF; M. McMahon, 2002; M. McMahon & W. Patton, 1995; W. Patton & M. McMahon, 1997, 1999) of career development has been proposed as a metatheoretical account…

This paper investigates a Deweyan interpretation of constructivism as a means of developing a rationale for teaching science. The paper provides a review of constructivism from recent science education literature, along with some relevant criticisms. The paper then presents an interpretation of Dewey's formulation of the role of knowing and…

It is increasingly important for timber companies to train managers in the principles and practices of sustainable forest management. One of the most effective ways to conduct such training is through use of visual training methods. This is partly because visual representations encode large amounts of information and help learners to grasp…

In this paper, we examine the instructional discourse of science lessons in two primary classrooms for explanations of bird adaptations for flight. We draw on case study data to describe ways in which student construction of explanations is scaffolded by the teachers. We recognized three categories of explanations developed in the discourse:…

This paper proposes an expanded conception of scaffolding with four key elements: (1) scaffolding agency--expert, reciprocal, and self-scaffolding; (2) scaffolding domain--conceptual and heuristic scaffolding; (3) the identification of self-scaffolding with metacognition; and (4) the identification of six zones of scaffolding activity; each zone…

Electronic collaborative learning environments for learning and working are in vogue. Designers design them according to their own constructivist interpretations of what collaborative learning is and what it should achieve. Educators employ them with different educational approaches and in diverse situations to achieve different ends. Students use…

Purpose: The purpose of this paper is to report and discuss research that sought to explore how the individually purposeful nature of new employee workplace learning might be understood through its conception as epistemological agency, that is, the personally mediated construction of knowledge. Design/methodology/approach: Using a sociocultural…

What, if anything, do teachers need to know about how the brain works to improve teaching and learning? After all, a plumber needs to know how to stop leaks--not the molecular structure of water. And one can learn how to use a computer without knowing how a computer chip works. Likewise, teachers need to know how to help students develop…

Teacher leadership has been shackled by archaic definitions of leadership and timeworn assumptions about who can lead. Such ideas have situated leadership in the hands of a few formal leaders. Teachers have not seen themselves reflected in these prevailing notions, nor invited into the process. This article argues that a new definition of…

This work is grounded in a constructivistic conception of the learning of science, more particularly on the model known as teaching-learning as oriented research. In accordance with this theoretical basis we have developed an empirical research project to investigate the teaching of electrostatics in high schools. The designs developed have…

This article traces the development of a contextual approach to the teaching of science (physics) subsequently called the Large Context Problem (LCP) approach. This approach is based on the general observation that learning could be well motivated by a context with one unifying central idea capable of capturing the imagination of the students. The…

This paper provides an overview and research summary of Direct Instruction (DI) mathematics programs, specifically "DISTAR Arithmetic I" and "II" (Engelmann & Carnine, 1975, 1976), "Corrective Mathematics" (Engelmann & Carnine, 1982), and "Connecting Math Concepts" (CMC; Engelmann, Carnine, Kelly, & Engelmann, 1996a). A comparison of the…
