The first year of a 5 year professional development project for elementary teachers in two mid-western states integrated a bridge of two distinctly different distance education networks (T-1 and fiber optics) to provide science professional development for elementary school teachers in rural communities. "Interactive television" (ITV), the title…

Tree rings can be used not only to look at plant growth, but also to make connections between plant growth and resource availability. In this lesson, students in 2nd-4th grades use role-play to become familiar with basic requirements of trees and how availability of those resources is related to tree ring sizes and tree growth. These concepts can…

Developing children's capacity to learn is at the forefront of all endeavours in schools. Teachers strive to capitalise on a wide range of teaching styles and innovations to stimulate, motivate and engage their children to become "better learners". Since September 1999, the Centre for Science Education at Sheffield Hallam University has…

The original project, the foundation for all subsequent work, was set up in 1981 by Michael Shayer, with Philip Adey and Carolyn Yates, and became known as CASE @ KS3 (Adey and Shayer, 1994). CASE stands for Cognitive Acceleration through Science Education. The original CASE project drew on Piaget's work on the stage theory of cognitive…

The Eden Project in Cornwall sets out to educate about the interdependence of plants and people. Its tropical and Mediterranean biomes are housed in the largest "greenhouses" in the world, which serve as a backdrop to plants that grow in the temperate zones of the world, grown in Eden's outdoor landscape. Eden has aroused worldwide…

This study examined students' alternative conceptions of reptiles and amphibians and the extent to which these conceptions remain intact through the elementary (grades 4 and 6), junior, and senior high school years. We administered multiple-choice and free-response instruments to a total of 513 students and interviewed at least 20 students at each…

Well-designed problems are crucial for the success of problem-based learning (PBL). Previous discussions about designing problems for PBL have been rather general and inadequate in guiding educators and practitioners to design effective PBL problems. This paper introduces the 3C3R PBL problem design model as a conceptual framework for…

In "Hands-On Science Mysteries for Grades 3-6," the authors connect science to real-world situations by investigating actual mysteries and phenomena, such as the strange heads on Easter Island, the ghost ship "Mary Celeste," and the "Dancing Stones" of Death Valley. The labs are designed to encourage the development…

This article describes the use of a lesson study approach to collaborative professional growth in an elementary science methods course. Preservice candidates designed and taught integrated science-mathematics lessons during the semester before their student teaching. Working in 8 teams of 3 student teachers, participants per team designed a common…

This is a checklist for use by science coordinators, school principals, science supervisors, and teachers in identifying strengths and weaknesses of science programs in grades kindergarten through 12. It can also be used by science coordinators during school visits. This guide contains space for recording information concerning: school name and…

Wildlife is often described as one of Alaska's most important and valuable resources. Helping wildlife can take many forms. This document contains the directions and parts of two games for use with the "Alaska Wildlife Week" materials. The games "Brant for the Future", a simulation of bird and human interactions in the Pacific…

Science is viewed as a neglected subject in many U.S. elementary schools. Many elementary school teachers feel unqualified and uncomfortable when asked to teach it. A study looked at a teacher who is enthusiastic about teaching science at the elementary school level. The constraints the teacher faced and ways in she dealt with them in her teaching…

This book helps teachers fulfill curriculum requirements by building both science content and process skills through hands-on exploration. Ten broad subject areas are covered: (1) Discovering Science, (2) Matter and Energy, (3) Humans, (4) The Environment, (5) Rocks, (6) Plants, (7) Living Creatures, (8) Weather, (9) The Heavens, and (10) Applying…

This resource for teachers of elementary age students provides a foundation for building a life-long interest in the U.S. space program. It begins with a basic understanding of man's attempt to conquer the air, then moves on to how we expanded into near-Earth space for our benefit. Students learn, through hands-on experiences, from projects…

This study was conducted to examine sex typing of mathematicians and scientists and to evaluate a course, "Equity Issues in a Technological Society," designed to sensitize students to gender inequities in education and to expose them to more equitable teaching strategies. Subjects were 248 entering undergraduate university students…
