An introductory guide to deducing the mechanism of chemical reactions is presented. Following a typical workflow for probing reaction mechanism, the guide introduces a wide range of kinetic and mechanistic tools. In addition to serving as a broad introduction to mechanistic analysis for students and researchers, the guide has also been used by…

The ability to become a scientifically literate citizen rests on the foundation students build from elementary, middle, and high school science experiences. The North Carolina Science Standard Course of Study (SCS) provides the concepts and theories all students should understand. Strands unify the goals and objectives and reflect a science as…

The concept of paraphyly is defined and its importance in the teaching of evolution and taxonomy is discussed. Examples are included to illustrate this concept. A list of 14 references is provided. (CW)

The Colorado Model Content Standards for Science specify what all students should know and be able to do in science as a result of their school studies. Specific expectations are given for students completing grades K-2, 3-5, 6-8, and 9-12. Five standards outline the essential level of science knowledge and skills needed by Colorado citizens to…

Assessment, when integrated with instruction, can provide a basis for restructuring science education. The National Science Education Standards are incorporated into this guide to assessing student understanding in science. Chapters include: (1) "Assessment Based on Six Domains of Science," which organizes an assessment framework for…

Describes unexpected experiences with student laboratory activities. Makes recommendations for addressing two types of lab disasters: (1) when lab preparations fail prior to the beginning of lab; and (2) when students produce unexpected results with the proper use of materials. (Contains 11 references.) (WRM)

This document presents the revised Arkansas Science Curriculum Framework (1999), which replaces the Science Curriculum Framework of 1994. Three strands--physical science systems, life science systems, and Earth science/space science systems--were identified using an integrated approach to provide guidance in the science curriculum. A glossary and…

This document explains the Arkansas science benchmarks for grades 5-8 which were developed to provide guidance to science teachers. The content standards for three strands--physical science systems, life science systems, and Earth science/space science systems--were identified based on grade levels. (YDS)

Major concepts can help create thinking frameworks that are powerful enough to make additional input more meaningful. As a result, the content is richer, more diverse, and more widely applicable. This set of concept papers was produced because concepts are not uniformly understood by practitioners. Each is designed to introduce a concept and to…

This document explains the Arkansas science benchmarks for grades K-4 which were developed to provide guidance to science teachers. The content standards for three strands--physical science systems, life science systems, and Earth science/space science systems--were identified based on grade levels. (YDS)

A project was conducted in North Carolina to identify science competencies in three selected vocational programs: consumer and homemaking education, business and office education, and marketing and distributive education; to develop subcompetencies to reflect the science skills implied in the identified competencies; to validate the…

This handbook is a product of a research project conducted in North Carolina to identify science competencies taught in vocational agriculture programs. Specifically, two vocational agriculture courses were included in the study: Introduction to Agriculture/National Resources and Ornamental Horticulture I. Of the 60 competencies in the…
