Discusses the origins, makeup, and activities of child death review teams (CDRTs) used in 21 states in the states' quest to solve cases involving the suspicious death of a child. Advocates the creation of CDRTs in states which do not have them. (MDM)

The 16-week training program offered by the FBI Academy for all new agents is a scenario-based curriculum that includes a range of subjects from the rules of evidence to defensive tactics and provides agents with a clear understanding of how to conduct a full investigation from start to finish. (JOW)

Reports on rich mathematical activities that integrate different mathematics strands and learning. Describes how to introduce the task and the classroom setting, set up the task, and continue the investigation. Presents student work samples. (ASK)

Explores library-related implications of the U.S. Department of Justice's investigations into the operations of Microsoft and Intel and suggests that developing a broader understanding of information technology marketing is crucial to the short- and long-term future of libraries. (MES)

Discusses reasons why problem solving has failed. Offers an alternative approach--the use of investigations in mathematics instruction. Lists the characteristics of an idealized classroom. (ASK)

Describes the use of a graphing calculator-based laboratory (CBL) device that provides a portable data-collection system that students at high school and college levels can use to conduct projects in chemistry. Reviews possible uses for CBL in a chemistry program. (Author/CCM)

Several years ago, upon entering eighth grade, a student was given a Microsoft iPaq Pocket PC as a birthday present. After using it for several months, he noticed a distinct improvement in my grades. During the rest of the school year, he noticed that the improved academic achievement continued. He wondered if his experience was a mere fluke or…

This investigation compared fantasy-proneness levels and IQ scores in gifted adolescents with primary talent areas in 1 of 4 domains: mathematics, computer science, creative writing, and chemistry. The Inventory of Childhood Memories and Imaginings: Children's Form (ICMIC; Myers, 1983) was used to assess fantasy-proneness. IQ scores were generated…

This investigation presents a DFPN (Dynamic Fuzzy Petri Net) model to increase the flexibility of the tutoring agent's behaviour and thus provide a learning content structure for a lecture course. The tutoring agent is a software assistant for a single user, who may be an expert in an e-Learning course. Based on each learner's behaviour, the…

The development of a simple spectro photometric method to quantitatively determine the quantity of FD&C color additives present in powdered drink mixes, are focused by the investigations. Samples containing single dyes of binary mixtures of dyes can be analyzed using this method.

Kelley compared three methods for setting a confidence interval (CI) around Cohen's standardized mean difference statistic: the noncentral-"t"-based, percentile (PERC) bootstrap, and biased-corrected and accelerated (BCA) bootstrap methods under three conditions of nonnormality, eight cases of sample size, and six cases of population…

This investigation compared the prevalence rates of pathological and problem gambling between Greek-affiliated and non-Greek-affiliated college students. The 954 participants volunteered to take the South Oaks Gambling Screen (SOGS; Lesieur & Blume, 1987), which measures gambling disorders. A statistically significant association was found between…

Confidence intervals (CIs) give information about replication, but many researchers have misconceptions about this information. One problem is that the percentage of future replication means captured by a particular CI varies markedly, depending on where in relation to the population mean that CI falls. The authors investigated the distribution of…

The main goals of these activities are to help students learn how a convex lens can serve as a magnifying lens and how light travels and creates images. These explorations will introduce middle school students to different types of lenses and how they work. Students will observe and describe how lenses bend light that passes through them and how…

In this article, the authors describe an integrated science and literacy instructional model in which students build background knowledge by engaging in free-choice learning options during an investigation of school yard habitats. Students interact with their peers while inquiring, discussing findings, and using print resources to enhance learning.
