The Swift Turbidity Marker is an optical instrument developed to measure the level of water turbidity. The components and configuration selected for the system are based on common turbidity meter design concepts but use a simplified methodology to produce rapid turbidity measurements. This work is aimed at high school physics students and is the…

In this article, a group of inservice providers and beginning researchers describe their experiences in learning to conduct evaluation research on a long-term school-university partnership program. We offer the practical lessons we learned in how to undertake such a study, and we share the immediate and powerful effects that the process of…

Examining the extent to which the lived, embodied experience can be worded, a study integrating artistic research methodologies of narrating and perceptual practices was designed. The combined use of writing and moving showed the importance of non-languaged ways of knowing, building on the idea of an embodied cognition and the embodied mind, as…

To address the question of musical identity, the research the author mainly draws on takes the form of qualitative, in-depth interviews with people about how music fits into their everyday lives and musical biographies. In this the author adopts a largely biographical and social constructionist perspective, asking people to reflect on important…

More than a decade ago, art historian Carol Duncan (1993) questioned the legitimacy of the democratization of an "elite" liberal arts education, challenging assumptions held by educators, administrators, and scholars that "the democratization of an elite liberal arts education is possible." This study is a direct extension of Professor Duncan's…

This document is the first installment of this Forum (National Forum on Education Statistics) series of guides on longitudinal data systems (LDS). This book focuses on the fundamental questions of what an LDS is (and what it is not), what steps should be taken to achieve a sound system, what components make up an ideal system, and why such a…

DataPlay is a research project inspired by the concept of a "ludic age" (Chaplin & Zimmerman, 2008), where the challenges of extracting knowledge from the "data deluge" of the information age (Economist, 2010) are met with game-based approaches to information design. This paper examines Mannahatta: The Game in order to…

In the Information Age, a proliferation of unstructured text electronic documents exists. Processing these documents by humans is a daunting task as humans have limited cognitive abilities for processing large volumes of documents that can often be extremely lengthy. To address this problem, text data computer algorithms are being developed.…

The current study evaluated the performance of traditional versus modern MDTs in the estimation of fixed-effects and variance components for data missing at the second level of an hierarchical linear model (HLM) model across 24 different study conditions. Variables manipulated in the analysis included, (a) number of Level-2 variables with missing…

A post-WWII assignment from the U.S. Navy analyzing data from a test of a harbor mine-detecting algorithm leads to a new construction of the symmedian point.

Developing statistical literacy for older school students includes recognizing and interpreting conditional statements in the media. Data on couples' success in predicting whether their partners have cheated provides a motivating context for teachers to lead their students through this process.

Model building or model selection with linear mixed models (LMMs) is complicated by the presence of both fixed effects and random effects. The fixed effects structure and random effects structure are codependent, so selection of one influences the other. Most presentations of LMM in psychology and education are based on a multilevel or…

Complex survey data, as highlighted in this issue of "Evaluation Review", provide a wealth of opportunities for answering methodological and/or applied research questions. However, the analytic issues of nonindependence and unequal selection probability must be addressed when analyzing this type of data. Thus, to ensure that research questions are…

Although structural equation modeling software packages use maximum likelihood estimation by default, there are situations where one might prefer to use multiple imputation to handle missing data rather than maximum likelihood estimation (e.g., when incorporating auxiliary variables). The selection of variables is one of the nuances associated…

This paper examined observed score linear equating in two different data collection designs, the equivalent groups design and the nonequivalent groups design, when information from covariates (i.e., background variables correlated with the test scores) was included. The main purpose of the study was to examine the effect (i.e., bias, variance, and…
