We describe the design and implementation of a web-based statistical program—the Interactive Profiler (IP). The prototypical program, developed in Java, was motivated by the need for the general public to query against data collected from the National Assessment of Educational Progress (NAEP), a large-scale US survey of the academic state of American students. The emphasis of the program requirements is on bringing the NAEP data to a broader and not necessarily technically prepared audience. We show that the IP is an intuitive tool for visualizing students’ profiles. Because the same principles for visualization apply to other databases, in this article we also demonstrate how IP can be used to visualize a large marketing database. Besides NAEP, our statistical visualization tool should be pertinent to other federally maintained databases and large-scale marketing databases.

ABSTRACTBackground:Over the last several years, we have witnessed the metamorphosis of network biology from being a mere representation of molecular interactions to models enabling inference of complex biological processes. Networks provide promising tools to elucidate intercellular interactions that contribute to the functioning of key biological pathways in a cell. However, the exploration of these large-scale networks remains a challenge due to their high-dimensionality.Results:CrosstalkNet is a user friendly, web-based network visualization tool to retrieve and mine interactions in large-scale bipartite co-expression networks. In this study, we discuss the use of gene co-expression networks to explore the rewiring of interactions between tumor epithelial and stromal cells. We show how CrosstalkNet can be used to efficiently visualize, mine, and interpret large co-expression networks representing the crosstalk occurring between the tumour and its microenvironment.Conclusion:CrosstalkNet serves as a tool to assist biologists and clinicians in exploring complex, large interaction graphs to obtain insights into the biological processes that govern the tumor epithelial-stromal crosstalk. A comprehensive tutorial along with case studies are provided with the application.Availability:The web-based application is available at the following location: http://epistroma.pmgenomics.ca/app/. The code is open-source and freely available from http://github.com/bhklab/EpiStroma-webapp.Contact:[email protected]

A set of methods is proposed for the analysis of opportunity to learn (OTL) in relation to achievement in large-scale educational assessments. The focus is on how to assess the effect of OTL on performance while taking prior performance and other background factors into account. The methods are illustrated with mathematics data from the National Assessment of Educational Progress and from the National Education Longitudinal Study. Methods are discussed for combining OTL information, for studying the OTL sensitivity of test items, and for studying OTL effects in the context of multivariate proficiency scores as well as scores from several occasions. Implications for future large-scale educational assessments are discussed.

Plant roots are composed of many differentiated tissue types, with each tissue exhibiting differential quantitative and qualitative accumulation of metabolites. The large-scale nontargeted metabolite profiles of these differentiated tissues are complex, which complicates the interpretation and development of hypotheses relative to the biological roles of differentially localized metabolites. Thus, we created a data visualization tool to aid in the visualization and understanding of differential metabolite accumulations in Medicago truncatula roots. This was achieved through the development of the Medicago truncatula Metabolite Atlas based upon an adaptation of the Arabidopsis Electronic Fluorescent Pictograph (eFP) Browser. Medicago truncatula roots were dissected into border cells, root cap, elongation zone, mature root, and root secretions. Each tissue was then analyzed by UHPLC-QTOF-MS and GC-Q-MS. Data were uploaded into a MySQL database and displayed in the Medicago truncatula Metabolite Atlas. The data revealed unique differential spatial localization of many metabolites, some of which are discussed here. Ultimately, the Medicago truncatula Metabolite Atlas compiles metabolite data into a singular, useful, and publicly available web-based tool that enables the visualization and understanding of differential metabolite accumulation and spatial localization.

This article develops and evaluates a linkage of a routinely administered measure, the Armed Services Vocational Aptitude Battery (ASVAB), to a large-scale assessment, the mathematics proficiency scale of the National Assessment of Educational Progress (NAEP). Analyses of both simulated and real data indicated that the statistical accuracy of the proficiency distribution estimated by projection (i.e., by regression on the ASVAB sub-scales) was very close to the accuracy obtained by the use of the NAEP methodology. However, for both methods, proficiency may have been systematically underestimated because of motivational factors in the administration of the NAEP measures to examinees in this study.

In the current implementation in the form of software,Web-based B/S structure has been a wide range of applications.With the gradual expansion of the scale of software for such systems need to have a good framework to support the development and maintenance processes. Quality system plays an important role in the whole system.This paper describes the design process of a good Web-based system framework from the perspective of practical application.Through practice, this framework can well support large-scale software development and maintenance process, the various types of cost savings for the enterprise.

Large-scale testing is dominated by the multiple-choice question format. Widespread use of the format is explained, in part, by the ease with which multiple-choice items can be scored automatically. This article examines automated scoring procedures for an alternative item type: figural response. Figural response items call for the completion or modification of figural material, including illustrations, diagrams, and graphs. Nineteen science items were written in cooperation with the National Assessment of Educational Progress and printed with a special ink, invisible to scanning equipment. The items were answered with pencils; response sheets were then scanned and the resulting data were processed by computer-based scoring algorithms. Implications of this technology for the future of large-scale testing are discussed.
