This laboratory exercise introduces students to a fundamental tool in evolutionary biology--phylogenetic inference. Students are required to create a data set via observation and through mining preexisting data sets. These student data sets are then used to develop and compare competing hypotheses of vertebrate phylogeny. The exercise uses readily…

White and group used a two question, open-ended tests to separately evaluate students' learning of specific biochemical concepts in the general biology lecture and laboratory, in the first performance assessment of molecular visualization in teaching biochemistry. Two studies were devoted to protein structure using globins followed by one…

A compilation of BASIC computer programs developed by teachers and students involved in the Huntington Computer Project is presented. The programs are grouped by subject area. The six subject areas are biology, earth science, chemistry mathematics, physics, social studies, and teacher assistance. For each program, the following information is…

Educationists are of the opinion that the educational problems relating to quantity and quality could be tackled by the proper utilization of instructional technology. Instructional technology is a systematic way of designing, carrying out and evaluating the teaching learning process. Instructional technology makes instruction more effective,…

This paper reports sex education preferences from an ethnically diverse sample of 3007 15-18 year olds. Findings are presented on preferred topics, where and from whom young people would like to receive this information. Preferences were centred around learning more about sexual behaviour and sexually transmitted infections (STIs) in particular,…

The Science Foundation Programme (SFP) at the University of KwaZulu Natal, Pietermaritzburg attempts to address past educational inequalities by providing disadvantaged matriculants with the skills, resources and self-confidence needed to embark on their tertiary studies. Students entering the Programme typically adopt a surface approach to…

The authors test biosocial models that posit interactions between biological variables (testosterone, estradiol, pubertal status, and pubertal timing) and social context variables (family, peer, school, and neighborhood) in predicting adolescent involvement with cigarettes and alcohol in a sample of 409 adolescents in Grades 6 and 8. Models…

This document is the 16th issue of an annual series of bibliographic work in New Zealand.

This book is a comprehensive resource of illustrative cases for classroom discussion of research ethics in the natural sciences, the behavioral sciences, and the humanities. The materials selected for inclusion are intended to speak to people in all disciplines, though the cases are drawn from biology, psychology, and history. They cover such…

The goal of this guide is to address a major environmental dilemma: worldwide habitat destruction and the disappearance of species. This guide is one of six that are included in the Habitat Ecology Learning Program (HELP), a holistic life science curriculum that involves students in an in-depth study of ecology. HELP includes six teaching guides…

The booklet is part of a grade 10-12 social studies series produced for bilingual education. The series consists of six major thematic modules, with four to five booklets in each. The interdisciplinary modules are based on major ideas and designed to help students understand some major human problems and make sound, responsive decisions to improve…

This document consists of the first two volumes of a new annual serial devoted to surveying some of the important developments in the mathematical sciences in the previous year or so. Mathematics is constantly growing and changing, reaching out to other areas of science and helping to solve some of the major problems facing society. Volumes 1 and…

As part of an investigation of the influence of a 3-week institute upon secondary biology and earth science teachers regarding their self-confidence with respect to the teaching of evolutionary principles, 19 inservice teachers participated in discussions of content presentations and instructional activities. The following research questions were…

This paper reports the results of a study designed to examine how students with different learning styles functioned in World Wide Web-based courses offered by Project BIO at Iowa State University in the Fall of 1997, and to determine what factors influenced their learning. The objectives of the study were to identify: (1) the demographic…

The 18 brief articles contained in this booklet reflect an attempt by science and math teachers in Nevada to explore ways to rekindle the exhileration of discovery for themselves and their students that began with the knolwedge explosion that followed the launching of Sputnik in 1957 but that was eventually washed away in a flood of…
