Pedagogical content knowledge (PCK) is a much debated and studied construct. In this article, we adopt an all-embracing view of PCK to examine the development of one elementary science teacher's knowledge over a 10-year period. We portray this teacher's knowledge at three critical points in her career--as a student teacher, beginning teacher, and…

Teaching strategies are becoming increasingly oriented toward guiding students' knowledge construction through cooperative learning. Enhancing students' cognitive development is a priority; students must "learn how to think." Inquiry instruction provides students with tools to make decisions based upon available evidence and an opportunity to…

In this activity, students learn about the important topic of invasive species, specifically Zebra Mussels. Students role-play different characters in a real-life situation: the trial of the Zebra Mussel for unlawful disruption of the Great Lakes ecosystem. Students will also learn about jurisprudential inquiry by examining the trial process. This…

Analyzes unique within district variations in spending and achievement among urban public elementary schools (n=89). Reveals considerable disparities in spending linked to local patterns of racial and class stratification and concentration. Shows how these local driven inequalities have consequences for achievement in reading, writing,…

This inquiry-based lab is designed around genetic diseases with a focus on protein structure and function. To allow students to work on their own investigatory projects, 10 projects on 10 different proteins were developed. Students are grouped in sections of 20 and work in pairs on each of the projects. To begin their investigation, students are…

"Elementary Science: Where are We Now?" is a review of Elementary Science Education from the 1960s to 1999. Curriculum moved from uniform programs in the 1960s based on two assumptions to a wide diversity of goals, philosophies, and types of materials in the 1970s. The two assumptions behind the elementary science curriculum programs of…

This study reports research findings on assessment of the science classroom learning environment and its association with two student outcomes--attitudes toward science and national examination scores. Modified versions of the WIHIC and TOSRA questionnaires in the Indonesian language were administered to 1400 students and their teachers. This…

The purpose of this study was to examine problem-based learning (pbl) and how students in the middle grades math and science classroom perceived its effectiveness. Analysis of student perceptions of changes in their learning processes and self-efficacy was analyzed through student interviews. Data identified the components of changes in students'…

Rather than focusing on teaching teachers, university researchers helped local teachers study what students thought about math and science ideas--with powerful results. As teachers understood what students were thinking, they modified their practices to promote deeper understanding. Their collaboration created bottom-up change.

The Teacher-Centered Systemic Reform model (TCSR) recognizes teaching context, teacher characteristics, teacher thinking, and their interactions as influential factors in attempts to implement classroom reform. Using the TCSR model, teachers' personal practical theories, and conceptual change as a framework, the authors of this article studied…

The research reported here focuses on links between teachers' comprehension of the underlying physics and their development of educational strategies for classroom work during in-service training. It deals with the teaching of hydrostatics, a topic considered particularly interesting by teachers. Starting from the analysis of simple experiments…

In today's climate of content standards and high-stakes testing, science teachers are under more pressure than ever to focus on the "ready-made" knowledge of science content. Yet, science educators have long advocated a more balanced approach to science instruction, including emphasis on the processes by which scientific knowledge is produced, as…

Although numerous programs have been developed for Grade Kindergarten through 12 science education, evaluation has been difficult owing to the inherent problems conducting controlled experiments in the typical classroom. Using a rigorous experimental design, we developed and tested a novel program containing a series of pharmacology modules (e.g.,…

Written by a prominent array of scholars and practitioners, this book elucidates the complexities, contradictions, and confusion surrounding adolescence in American culture and education. For too long, harmful public myths and lies have portrayed teenagers as a principal cause of our nation's social ills. Similar unfair charges have been lodged…

The purpose of this study was to examine the extent to which preservice elementary teachers were able to construct viable scientific models with a computer-modeling tool, namely Model-It, and design a science lesson with models. The results of the study showed that (a) Model-It, through its scaffolds (i.e., Plan, Build, and Test modes), enabled…
