Exploratory data analysis (EDA), data visualization, and visual analytics are essential for understanding and analyzing complex datasets. In this project, we explored these techniques and their applications in data analytics. The case discusses Tableau, a powerful data visualization tool, and Google BigQuery, a cloud-based data warehouse that…

The EdSurvey package helps users download, explore variables in, extract data from, and run analyses on large-scale assessment data. The analysis functions in EdSurvey account for the use of plausible values for test scores, survey sampling weights, and their associated variance estimator. We describe the capabilities of the package in the context…

Experiential learning opportunities have been proven effective in teaching applied and complex subjects such as business analytics. Current business analytics pedagogy tends to focus heavily on the modeling phase with students often lacking a comprehensive understanding of the entire analytics process including dealing with real-life data that are…

Engaging with primary researchers during qualitative secondary analysis is a practice much recommended but rarely written about. In this article, I reflect on my experience of crossing an imagined boundary between the discrete textual dataset and its creators, of acknowledging and engaging with those researchers who invested in constructing the…

Analyses of student data in post-secondary education should be sensitive to the fact that there are many different topics of study. These different areas will interest different kinds of students, and entail different experiences and learning activities. However, it can be challenging to identify the distinct academic themes that students might…

This paper gives a detailed overview of the archived language documentation materials for the two languages spoken in northern Ambrym, Vanuatu: North Ambrym and Fanbyak. I discuss the speakers and the language situation in northern Ambrym to give readers an introduction to the culture of the area. The archived materials encompass five different…

Data mining methods for classification and regression are becoming increasingly popular in various scientific fields. However, these methods have not been explored much in educational measurement. This module first provides a review, which should be accessible to a wide audience in education measurement, of some of these methods. The module then…

This paper presents two interactive visualization tools for learning management systems (LMS) in order to improve learning and teaching in online courses. The first tool was developed at the Intelligent Information Systems Laboratory (IISLab) at the Tampere University of Technology (TUT). The tool is used to analyse students' activity from…

Smartphone ownership among college-aged Americans is high and growing, and many students own more than one mobile device. Such devices are increasingly incorporated into the academic lives of students, and the era of "bring your own everything" presents new opportunities and challenges for higher education. Mobile data collection is the…

This article examines issues faced by scholarly societies that are developing and sustaining online paper repositories. It is based on the AERA Conference on Online Paper Repositories, which focused on fundamental issues of policy and procedure important to the operations of online working paper repositories. The report and recommendations address…

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…

Explores factors in the history of the Open Archives Initiative (OAI) that have contributed to the positive response of the digital library and information community toward version 2 of the OAI Protocol for Metadata Harvesting. Factors include focus on a defined problem statement, an operational model in which strong leadership is balanced with…

These six articles discuss knowledge discovery in databases (KDD). Topics include data mining; knowledge management systems; applications of knowledge discovery; text and Web mining; text mining and information retrieval; user search patterns through Web log analysis; concept analysis; data collection; and data structure inconsistency.

Investigates cognitive effects of history doctoral students writing information about names pertinent to their study on index cards and recognizing patterns among the data elements. Highlights include schemata theory; theories on expert cognition; the development of expert thinking; and an information retrieval system that facilitates name…

Discusses the retrieval dimensions of data collection activity online and their influence on the research evaluation outcome to reinforce the link between online retrieval and bibliometrics. Topics include publication counts; citation analyses; citation databases from the Institute for Scientific Information; and data set isolation. (Author/LRW)
