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 enthusiasm for science displayed by students in early elementary grades is unparalleled. If not nurtured in elementary school, the spark for learning science diminishes. Unfortunately, the amount of time spent on science in Grades 1-4 has steadily declined since the passage of the No Child Left Behind Act of 2001. In 2012, the National…

Presents a procedure for designing management simulation games in which a series of progressively detailed documents describing the game are prepared until a blueprint of the developed game has been created. The development sequence is described in detail and two tables listing the phases of game documentation accompany the text. (JL)

Examines backward chaining, a method of producing demonstration films in which sequential steps in a procedure are taught backwards; that is, the last step is taught first, then the next to the last step, and so on. A film designed to teach procedures used in a science experiment is used as an example. (JJD)

Video games have a potential role in analysis of motor learning through laboratory tasks. This article discusses why games meet the requirements of laboratory tasks and suggests types of training and research that could be carried out using them. (PP)

This informational packet contains the materials necessary to administer the annual Department of Defense Dependent Schools Pacific Region Junior Science and Humanities Symposium (JSHS) at the high school and middle school levels. The symposium program is a calendar year research program which includes one week symposium of students (grade 8-12)…

This article suggests the use of structural equation modeling in special education research, to analyze multivariate data from both nonexperimental and experimental research. It combines a structural model linking latent variables and a measurement model linking observed variables with latent variables. (Author/DB)

Argues that K-12 students in the United States will continue to lack essential science knowledge until teachers are more knowledgeable about science, science curricula are restructured, and more varied science books are available. Highlights print and Web resources dealing with earthquakes and volcanoes, the heart, science experiments at home, and…

This information booklet contains the information necessary to administer the annual Department of Defense Dependent Schools Pacific Region Junior Science and Humanities Symposium (JSHS) at the school level. It is intended to be used by teachers and administrators as they manage the JSHS program within their schools and by students as they conduct…

Describes a full day of chemistry fun and competition for high school chemistry students. Notes teams have five students from each high school. Lists five competitive events for each team: titration, qualitative analysis, balancing equations, general chemistry quiz, and quantitative analysis with atomic absorption spectroscopy. (MVL)

The National Institute of Child Health and Human Development (NICHD) Study of Early Child Care is an ongoing, prospective, 3-year longitudinal study of over 1,300 full-term healthy infants and families from 10 sites across the United States. While the sample is not nationally representative, the subjects come from major regions of the country: the…

Discusses integrating mathematics/science with measurement for grades 6-12. Provides Web addresses for companies manufacturing data grabbers (instruments for gathering data in electronic form for graphing and analysis by graphing calculators and computers) and for sites offering instructional materials. Describes projects in architecture,…
