A simple experiment is described that permits advanced undergraduates to learn the principles and applications of the cavity ring down spectroscopy technique. The apparatus is used for measurements of low concentrations of NO[subscript 2] produced in air by an electric discharge. We present the setup, experimental procedure, data analysis and some…

Reporting methods used in large-scale assessments such as the National Assessment of Educational Progress (NAEP) rely on latent regression models. To fit the latent regression model using the maximum likelihood estimation technique, multivariate integrals must be evaluated. In the computer program MGROUP used by the Educational Testing Service for…

The Stages of Change Model (J. O. Prochaska & C. C. DiClemente, 1984) has been used to explore women's process of leaving relationships involving intimate partner violence. Using a strengths-based approach, this study aims to build upon the model to further theorize the process of leaving. We conducted secondary data analysis of interviews with 19…

J. Brooks-Gunn, W. J. Han, and J. Waldfogel (2002) and the National Institute of Child Health and Human Development Early Child Care Research Network (ECCRN; 2000b) came to different conclusions about the effects of maternal employment--although they were addressing similar questions using the same data set. Brooks-Gunn et al. concluded that…

Background: Studies suggest that expert performance in sport is the result of long-term engagement in a highly specialized form of training termed deliberate practice. The relationship between accumulated deliberate practice and performance predicts that those who begin deliberate practice at a young age accumulate more practice hours over time…

We present evidence from a new comprehensive database of harmonized national time-diary data that standardizes information on almost 40 years of daily life in America. The advantages of the diary method over other ways of calculating how time is spent are reviewed, along with its ability to generate more reliable and accurate measures of…

Managing data collected from online surveys may be a straightforward process involving no more than downloading a spreadsheet from a Web survey host and presenting descriptive statistics associated with each questionnaire item. On the other hand, if the evaluation objectives require more complex analysis and presentation of the data, it will be…

While individual data form the base for much empirical analysis in education, this is not the case for analysis of technical efficiency. In this paper, efficiency is estimated using individual data which is then aggregated to larger groups of students. Using an individual approach to technical efficiency makes it possible to carry out studies on a…

As part of longitudinal research on the role and scope of portfolios in teacher education programs, this study employs a case study approach to systematically examine the portfolio contents and reflections of three teachers enrolled in an advanced professional development master's degree program in education; the three teachers were purposely…

There is a big boom in manpower requirements in IT industries in India in recent years. Presently India is aiming at becoming the major source of manpower in IT and other technical fields in the global scenario. To achieve this target, enhancement of employability of graduates coming out of engineering colleges are very important. A study has been…

New Mexico Mathematics Content Standards, Benchmarks, and Performance Standards identify what students should know and be able to do across all grade levels, forming a spiraling framework in the sense that many skills, once introduced, develop over time. While the Performance Standards are set forth at grade-specific levels, they do not exist as…

This book is a practical, hands-on guide to using commonly available everyday technology, including Microsoft software, to manage and streamline research projects. It uses straight-forward, everyday language to walk readers through this process, drawing on a wide range of examples to demonstrate how easy it is to use such software. This guide is…

Teaching students to collect data to answer questions is an important life skill that will serve them well throughout their adult lives. The purpose of this manuscript is to describe the implementation of an action research project in a fifth grade resource classroom. Students with mild disabilities were taught how to conduct surveys using three…

The potential for response variability to serve as an endophenotype for attention deficit hyperactivity disorders (ADHD) rests, in part, upon the development of reliable and valid methods to decompose variability. This study investigated the specificity of intra-individual variability (IIV) in 53 children with ADHD by comparing them with 25…

The flattening world, growing expectations of accountability, and retiring baby boomers are just a few of the issues in the rapidly changing work environment that make it essential for colleges and universities to understand a wider variety of business affairs data in order to be competitive and effective. To meet these challenges, institutional…
