This study examined the effect of scaffolding learning components in a computerized environment, for students solving qualitative science problems in a simulation of laboratory experiments. Four scaffolding components were identified (structural, reflective, subject-matter and enrichment) and used in different configurations to construct four…

A new, integrated laboratory curriculum was recently developed at the U.S. Naval Academy in response to the 1999 ACS Committee on Professional Training guidelines that required inclusion of biochemistry and a stronger emphasis on student research. To meet these ACS requirements and to introduce more student choice in the major, we embarked on a…

Teachers can use pedometers to facilitate inquiry learning and show students the need for mathematics in scientific investigation. The authors conducted activities with secondary students that investigated intake and expenditure components of the energy balance algorithm, which led to inquiries about pedometers and related data. By investigating…

This paper presents the development of a 3-D virtual environment in Second Life for the delivery of standards-based science content for middle school students in the rural Appalachian region of Southeast Ohio. A mixed method approach in which quantitative results of improved student learning and qualitative observations of implementation within…

The WWW is now in widespread use for delivering on-line learning content in many large-scale education settings. Given such widespread usage, it is feasible to accumulate data concerning the most useful learning experiences of past students and share them with future students. Browsing events that depict how past students utilized the learning…

Although over 15 years have passed since Witt (1990) noted that no empirical evidence exists to support the contention that a collaborative approach to consultation leads to more positive outcomes than a hierarchical or expert driven approach, this issue generally remains unaddressed (Schulte & Osborne, 2003). While the literature documenting…

In January 2006, every science department chair in U.S. public, private, and parochial high schools received information on food science, including a DVD, poster, and experiment guide developed by the Institute of Food Technologists (IFT), IFT Foundation, and Discovery Education. To promote the experiments and to encourage implementation of the…

This article describes a novel, hands-on method to qualitatively determine the extent of microbial activity in topsoil using ordinary blank paper. Appropriate and scalable for the high school and college level, these experiments expose students to some of the challenges facing environmental researchers and also contribute to curriculum development…

Students in three levels of high-school physics classes (advanced, regular, and general) were studied as they learned concepts about gravity, balanced forces, and projectile motion to examine the effect of text and instructional techniques, such as prediction and labs, on learning. Reading appeared to be an effective influence on learning…

This classroom kit, designed by curriculum developers working with teachers and scientists from the SETI (Search for Extraterrestrial Intelligence) Institute, helps teachers guide students in the exploration of life through the multidisciplinary sciences of paleontology and exobiology. It reflects the real-life methods of science: making…

The activities in this guide (for grades 2-4) transport students to the sandy shore, one of the most fascinating ecosystems on the planet. At this ecological juncture a multiplicity of life forms find ways to survive, thrive, and interact with each other. Using a wide variety of learning formats, students explore and deepen their understanding of…

This book was written to make it easier for classroom teachers to teach students the skills they need to successfully conduct, analyze, and report an experiment and to carry out independent research; it also presents strategies for holding successful science competitions. Part 1 contains field-tested teaching strategies for developing student…

This paper addresses the role experiments can play in concept development. The study used a qualitative phenomenography research methodology. The interactions of one student with an instructor in a series of eight sessions on electric circuits is reported. The first three session focused on diagnosing the students' prior conceptions of electric…

This teacher's guide on acid rain is divided into three study areas to explain: (1) what causes acid rain; (2) what problems acid rain has created; and (3) what teachers and students can do to help combat acid rain. Instructions for activities within the study areas include suggested grade levels, objectives, materials needed, and directions for…

Unified Technical Concepts (UTC) is a modular system for teaching applied physics in two-year postsecondary technician programs. This UTC laboratory textbook, the first of two volumes, consists of 56 learning modules dealing with basic concepts of physics. Addressed in the individual chapters of the guide are the following topics: force, work,…
