The present study compared the relative effects of 2 educational programs on kindergarten children. The experimental group took part in a numeracy-specific program, which focused on conceptual knowledge. Children were taught basic numerical skills such as understanding and handling numbers and their relations as well as counting principles. The…

Working from the 1970s to the early 1990s, Walter Alvarez and his research team sought the cause of the mass extinction that claimed the dinosaurs 65 million years ago. The present paper discusses that research in terms of eight puzzling observations, eight episodes of hypothetico-predictive reasoning, enumerative induction, and Jung's…

In this article, we describe a collaborative design initiative with three secondary school teachers to promote the use of Web-based inquiry in the context of a watershed investigation. Design interviews that focus on instructional goals and pedagogical beliefs of classroom teachers were conducted. The interview protocol used a curricular framework…

I propose that for ethics to become a normal activity, practiced by citizens on a daily basis, we begin by identifying barriers to this activity. Once things that get in the way have been identified, I examine ways that environmental educators can create conditions for ethics to become part of mainstream practices and processes of inquiry--to…

Using Kazemi's and Stipek's (2001) framework of classroom practice, the discourse between students enrolled in a mathematics-for-teachers course and their instructor is examined. The teacher's practice is in transition from a focus on having students share multiple strategies toward a practice that additionally includes the mathematical…

Past studies reveal that science safety in the nation's schools needs significant attention (Gerlovich and Parsa 2002; Gerlovich et al. 2002; Gerlovich, Wilson, and Parsa 1998; and Young 1972). These studies have focused on individual states and the issues and hazards specific to those states. A comprehensive study is needed to identify and…

Science teachers continually search for effective ways to help students make sense of science concepts and principles. For students to learn to think more like scientists, science teachers must decrease the number of lectures and "follow-the-recipe" laboratory experiments and increase the use of activities that incorporate student inquiry.…

The study describes teachers' collective work in which they developed deeper understanding of their own students' mathematical thinking. Teachers at one school met in monthly workgroups throughout the year. Prior to each workgroup, they posed a similar mathematical problem to their students. The workgroup discussions centered on the student work…

In the context of U.S. and world wide educational reforms that require teachers to understand and respond to student thinking about mathematics in new ways, ongoing learning from practice is a necessity. In this paper we report on this process for one teacher in one especially productive year of learning. This case study documents how Ms. Statz's…

This unconventional essay is the (slightly modified) transcript of the question-and-answer period of an AERA conference session on the topic of paradigm proliferation. Through responses to the discussants prepared questions and audience members' comments and questions, each panelist extends and defends the ideas put forward in her or his paper and…

Utilizing an integration of social-cognitivist and socio-cultural approaches, this study--comparing the interactive processes among peers and their mentor in two contrasting groups--was designed to explore the reasons why two learning groups, engaged in an inquiry-based learning project with comparatively sustained discussion, produced vastly…

This article uses a sociocultural approach to analyze how trajectories of identity development and learning intersect in actions carried out in a community of learners. The approach utilizes a framework for analysis with 5 aspects: the action, the agents, the goals, the cultural tools, and the scene. The study posits a distinction between mastery…

Reflection has long been an aspiration in education, from Aristotles Nicamachean Ethics, through Bacons (1605) Advancement of Learning and later articulated by John Dewey. Schon's reflective practitioner underpins the ethos in the professional training of teachers in the UK. This paper reviews approaches to reflection in learning and argues that…

Since Fall 2001, the faculty and leaders of the Teacher Education Program (TEP) at the University of California, Los Angeles, have participated in a collaborative inquiry project. This five-year research endeavor provides opportunities for teacher educators, assisted by university researchers, to study their own practice. This paper presents an…

Practitioner research is defined as systematic inquiry-based efforts directed towards creating and extending professional knowledge and associated understandings of professional practice. A review of "primary research" articles published in the "Australian Journal of Early Childhood" revealed that only a small number involved…
