Missing data are a common occurrence in survey-based research studies in education, and the way missing values are handled can significantly affect the results of analyses based on such data. Despite known problems with performance of some missing data handling methods, such as mean imputation, many researchers in education continue to use those…

The growth in the availability of longitudinal data--data collected over time on the same individuals--as part of program evaluations has opened up exciting possibilities for evaluators to ask more nuanced questions about how individuals' outcomes change over time. However, in order to leverage longitudinal data to glean these important insights,…

Researchers in career and technical education often ignore more effective ways of reporting and treating missing data and instead implement traditional, but ineffective, missing data methods (Gemici, Rojewski, & Lee, 2012). The recent methodological, and even the non-methodological, literature has increasingly emphasized the importance of…

We review the history and current trends in the field of Educational Data Mining (EDM). We consider the methodological profile of research in the early years of EDM, compared to in 2008 and 2009, and discuss trends and shifts in the research conducted by this community. In particular, we discuss the increased emphasis on prediction, the emergence…

The efficacy of online learning programs is tied to the suitability of the program in relation to the target audience. Based on the dataset that provides information on student enrollment, academic performance, and demographics extracted from a data warehouse of a large Southwest institution, this study explored the factors that could distinguish…

Examples of the use of Multiple Linear Regression (MLR) techniques are presented. This is done to show how MLR aids data processing and decision-making by providing the decision-maker with freedom in phrasing questions and by accurately reflecting the data on hand. A brief overview of the rationale underlying MLR is given, some basic definitions…

Ethnography may be used to inform the audience of a curriculum program with the activities of the educators and students involved. Thus the expository function of evaluation is best met by ethnography. A conceptual model developed at the Central Midwestern Regional Educational Laboratory incorporates ethnographic data and techniques into…

In the first of a two-part document, the Westinghouse Learning Corporation delineates the major aspects of research to be carried out in the experimental leadership course instituted at the United States Naval Academy (the final report appears under EM 010 418, EM 010 419, and EM 010 484). Specific topics covered in this part include validation of…

In the second of a two-part document (part I is under EM 010 475), the Westinghouse Learning Corporation provides further details on the research to be carried out in the experimental leadership course instituted at the United States Naval Academy (the final report appears under EM 010 418, EM 010 419, and EM 010 484). Further details are…

This report is the first of a two-part document which presents the results of the research conducted during the first implementation of the leadership, psychology and management course at the United States Naval Academy. A detailed discussion of the background of the research, the research plan, and its implementation is provided. The second part…

An explication of the modification to the research design for the second implementation of the United States Naval Academy leadership course developed by the Westinghouse Learning Corporation is provided. A comparison is made, where applicable, of the results of the experimental manipulations in the spring and fall implementations. A summary of…

This book is developed from the proceedings of a symposium sponsored by the Office of Naval Research and the System Development Corporation. It presents a survey and a practical guide for formulating individual application requirements and forecasting future availability of data processing capabilities. Part I consists of seven articles covering…

The 7th International Conference on Education Data Mining held on July 4th-7th, 2014, at the Institute of Education, London, UK is the leading international forum for high-quality research that mines large data sets in order to answer educational research questions that shed light on the learning process. These data sets may come from the traces…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
