This aim of this study was to analyze the content of students' verbal interactions within a problem-based learning context in biology. This was achieved through the qualitative analysis of the verbal protocols of three groups of two clases of ninth-grade female students (average/high ability, high/high ability, and average/average ability). The…

This paper describes a method for teaching introductory biology using a multimedia approach. This methodology aimed to increase student participation, promote independent learning, and enhance computer literacy. Five multimedia tools were used to teach the course. PowerPoint slide shows were used to present lecture material; videodiscs displayed…

This study investigated the effects of audio, animation, and spatial ability in a computer-based instructional program for biology. The program presented instructional material via test or audio with lean text and included eight instructional sequences presented either via static illustrations or animations. High school students enrolled in a…

This report presents the results of a study conducted during the 1995-1996 school year to evaluate the educational progress of 12th grade students taking advanced biology, chemistry, and physics courses.

This guide features a problem-based learning (PBL) unit specifically designed for student-centered learning of new and meaningful content on diseases. Students grapple with a complex and changing problem that requires higher level thinking skills in an environment in which students work both individually and in collaboration with others. Includes…

This paper describes changes in students' ideas about science classes, attitudes about science, and motivations for studying science in a classroom designed to support project-based science learning. Findings indicate that providing students with opportunities to collect and analyze their own data in science classes results in a change in…

This publication is a compilation of examples of practical, easily implemented activities to help mathematics, science, and education faculty duplicate efforts by the Rocky Mountain Teacher Education Collaborative (RMTEC) to reform and revise curriculum for preservice educators. Activities are organized by content areas: mathematics; geology,…

This booklet introduces guidelines for teachers at any grade level to set up and maintain a simple aquarium and through it introduce simple biological ideas to their students. Natural and cost-saving aquarium-running strategies are discussed and common, hardy fish and plant choices are described. Many demonstrations and experiments are included on…

This guide provides an introduction to the study of reptiles and amphibians and presents opportunities for young people to become involved in their conservation. This book is designed as an instructional guide for many educators in various settings from classroom to nature center. The material provides a thorough introduction to the world of…

This report summarizes the presentations and discussion at a workshop on adolescent sleep. The workshop was organized by the Board on Children, Youth, and Families and the Forum on Adolescence of the National Research Council and Institute of Medicine. The workshop brought together policy makers, researchers, and practitioners to examine research…

Evaluated teaching activites focusing on scientific concept of "animal" with three age groups: 5 (N=15), 9/10 (N=23) and 14 (N=20). Results suggest that these activities modified some students' concept of "animal" toward the scientific one, and that not understanding basic concepts (such as animal) may cause difficulties in…

The University of Georgia (UGA) biosafety program was initiated in response to requirements for recombinant DNA experiments rather than laboratory-acquired infections. This and other environmental safety programs at UGA are described, considering three of the four recognized levels of biocontainment. A fire extinguisher inspection computer program…

Describes equipment for recording human breathing (stethographs, tambors, spirometers), construction of pooters (pipettes), field exercise on examining epiphyte distribution on tree bark, and vertebrate skeleton models for teaching locomotion. Includes abstract of student research project examining pH on Colpoda encystment and reviews of…
