A recursive scientific writing project was undertaken in a second-year, graduate-level course to teach students who were non-native English speakers to write scientific communications clearly and concisely in English. The instructor returned students' brief texts with editorial revisions marked to show how increased clarity may be achieved through…

We present an alternative to a traditional first-year chemistry laboratory experiment. This experiment has four key features: students utilize stoichiometry, learn and apply principles of green chemistry, engage in authentic scientific inquiry, and discover why each part of a scientific lab report is necessary. The importance and essential…

The results of previous educational research raise some questions about the efficacy of conventional teaching strategies and point to a need for using teaching strategies that explicitly take into account misconceptions students bring to the classes or acquire during the teaching-learning process. Accordingly, this article presents efforts to…

Classroom demonstrations are a great vehicle for getting students to apply information they have heard in a lecture. Educational research is replete with data showing that concept application in an inquiry setting reinforces long-term science content retention. This means that students learn best when they experience applications of concepts and…

Two job analyses were conducted to define knowledge domains for newly certified chemistry and physics teachers, respectively, to perform their jobs competently. The results of the job analyses will be used to develop test specifications for the Praxis II Series subject Assessments in Chemistry and Physics. Initial draft domains were prepared for…

These proceedings report the efforts of National Science Foundation researchers to disseminate innovations in undergraduate education. Section 1 contains forewords and keynote addresses by Robert F. Watson, Neal F. Lane, and Luther S. Williams. Section 2 contains overviews on dissemination and publishing including "Full-Scale Implementation: The…

This book includes four papers presented at a conference on teaching science to students with disabilities. The first paper, "Science Education for Motor/Orthopedically-Impaired Students" (E. C. Keller, Jr.), covers: (1) categories of motor/orthopedic-impairments, (2) life function assessment, (3) formal and informal science teaching…

Due to its abstract, theoretical nature, the mole concept has been recognized as one of the most difficult topics to teach and learn within the chemistry curriculum. The purpose of this study was to chronicle the development of high school students' conceptions of the mole following a period of instruction in a chemistry class. This investigation…

This curriculum unit on the ozone is intended for high school students and contains sections on environmental science and chemistry. It has been structured according to a learning cycle model and contains numerous activities, some of which are in a cooperative learning format. Skills emphasized include laboratory procedures, experimental design,…

ChemSource is designed as a strategy to help preservice and inservice high school chemistry teachers promote student learning more effectively. Its major premise is that well-designed laboratory investigations are an important avenue for cultivating student interest, engagement, and meaningful learning in chemistry. The SourceBook component of…

Although students' misconceptions about the concept of chemical equilibrium has been the focus of numerous investigations, few have investigated students' systematic errors when solving equilibrium problems at the college level. Students (n=189) enrolled in the second semester of a first year chemistry course for science and engineering majors at…

The purpose of this guide is to help students better understand the science, citizen action, and research issues that are part of the acid rain problem. The guide is designed for students in grades 4-8 and their teachers. Following an introduction, the first seven sections are informative in nature. They include: (1) "Observations about Acidity";…

This curriculum unit provides students with real world applications of science as it pertains to toxic releases into the environment. This boxed package contains the Toxics Release Inventory (TRI) Teacher's Guide, TRI Database Basics guide, comprehensive TRI compact disk with user's guide, "Getting Started: A Guide to Bringing Environmental…

The purpose of this study is to investigate the effects of two laboratory environments for introductory chemistry on undergraduate students' inquiry skills. The two laboratory environments are embedded in the same lecture course. The standard laboratory curriculum and instruction are distinct from the curriculum explored in this study, the MORE…

This bibliography contains some 2,000 articles on empirical investigation and theoretical considerations covering the topic of students' conceptions entered before September 1990. PUblications in journals, books, working papers, and contributions to conferences are included. English, German, and French publications, and ones in other languages are…
