In this article, the author describes another teacher's unique approach to teaching science in one unusual second grade classroom. Immediately upon entering the classroom, the author was surrounded by an array of colors, shapes, and objects typically found in a forest. A multitude of puppets, stuffed animals, and live animals filled the classroom.…

With the current focus on constructivist perspectives, science demonstrations have fallen out of favor in some circles. Demonstrations are easy to do and offer many benefits and unique opportunities in the constructivist classroom. With careful use, demonstrations can be powerful teaching tools. A wonderful quality of a demonstration (or a series…

To develop scientific literacy in today's global era, however, it is important that students learn about interactions within the Earth's systems worldwide. A unit exploring El Nino and La Nina-phenomena that can result in extreme weather events in locations all around the world-can help bridge this gap and broaden students awareness of global…

One of the most beneficial uses for technology in the science classroom is data manipulation. During labs and other learning experiences, students can quickly put the data they collect into spreadsheets or databases. Then they can make comparisons, create graphs, draw conclusions, sort the data in new ways, and, ultimately, give their data…

Learning communities (LC) seek to strengthen and enrich students' connections to each other, their teachers, and the subject matter they are studying. Their success depends on the nature of the learning community program, the learning styles of the students who participate and the reasons why students entered the program. This study uses a…

This paper examines the role adopted by teacher and youth work practitioners engaged in a project to carry forward practice in the handling of controversial issues in the contested society of Northern Ireland. First, it briefly outlines the development of work in the field during the 34 years of the present conflict, suggesting that to date too…

Over the last 5 years we have developed, produced, tested, and evaluated an authoring software package to produce web-based, interactive, audio-enhanced language-learning material. That authoring package has been used to produce language-learning material in French, Spanish, German, Arabic, and Tamil. We are currently working on increasing…

This project describes the trialling of a new form of cooperative learning strategy, in the form of a game known as "EcoRangers". "EcoRangers" is a multi-player game designed to run on mobile phones, written specifically for education. "EcoRangers" is one of the first, if not the world's first, instances of this…

This study investigated how individuals' construction of explanations--a way of ascertaining how well an individual understands a concept--develops from an interactive simulation. Specifically, the purpose was to investigate the effect of interactive computer simulations or science textbook assignments on the nature and quality of postgraduate…

Investigating local watersheds presents middle school students with authentic opportunities to engage in inquiry and address questions about their immediate environment. Investigation activities promote learning in an investigations interdisciplinary context as students explore relationships among chemical, biological, physical, geological, and…

Teachers can use inquiry to make sure that student learning is hands-on and minds-on. There are many levels of inquiry and teachers can even include some of their favorite cookbook labs after modifying them. Inquiry does not always mean lots of time, money, materials, and mess. One of the most important things that inquiry does require of…

The biasing effects of measurement error in path analysis models can be overcome by the use of latent variable models. In cases where path analysis is used in practice, it is often possible to use parcels as indicators of a latent variable. The purpose of the current study was to compare latent variable models in which parcels were used as…

This study investigates the cultural nature of teaching. It compares a sample of 39 videotaped Italian mathematics lessons to German, Japanese, and U.S. lessons videotaped in TIMSS. This study expands on earlier work that was based on a smaller sample; analysis is also extended to the nature of the mathematical content presented. The results…

In recent years, a growing interest has developed in lesson study, a Japanese form of professional development that centers on teachers coming together to examine their practice by planning and trying out lessons. This article examines the lesson study work of a group of elementary mathematics teachers to speculate about the educative value of…

This article presents a teaching experiment on the relationship between informal out-of-school and formal in-school mathematics, and the ways each can inform the other in the development of abstract mathematical knowledge. This study concerns the understanding of some aspects of the multiplicative structure of decimal numbers. It involved a series…
