We present a free student-facing tool for creating 3D plots and smartphone-based virtual reality (VR) visualizations for STEM courses. Visualizations are created through an in-browser interface using simple plotting commands. Then QR codes are generated, which can be interpreted with a free smartphone app, requiring only an inexpensive Google…

Sound educational policy recommendations require valid estimates of causal effects, but observational studies in physics education research sometimes have loosely specified causal hypotheses. The connections between the observational data and the explicit or implicit causal conclusions are sometimes misstated. The link between the causal…

This paper describes two classes of advanced data mining methods that can obtain actionable insight from cooperative education data: text mining of job descriptions and graph mining of job interview data. While these methods are not new in general, they have not been widely used in co-operative education research. A technical overview of each…

This paper addresses the question of identifying a concept dependency graph for a MOOC through unsupervised analysis of lecture transcripts. The problem is important: extracting a concept graph is the first step in helping students with varying preparation to understand course material. The problem is challenging: instructors are unaware of the…

The paper describes the importance of graphicacy as a key communication tool in our everyday lives. The need to better understand the development of graphicacy and its use in the school curriculum is emphasised. The need for a new research tool is explained and the development of a new taxonomy of graphicacy is described. The use of this tool…

Drawings offer new possibilities to develop understandings about how pre-service teachers experience becoming a teacher. It is in drawings that often "those elusive hard-to-put-into-words" (Weber & Mitchell, 2004) aspects of the self appear to add to the developing story of what it is to become a teacher. Using a triangulated…

Discusses use and misuse of the graphic representation of statistical data. Provides examples of misleading graphs. (PKP)

Describes the design and operation of four software packages, or macros, written in the programing language of Microsoft's EXCEL for use on the Macintosh computer for data manipulation and presentation used in educational research. Reordering tabulated data, reversing the scoring of tabulated data, and creating tables and graphs are explained.…

A nontechnical exposition of graph theory is presented, followed by survey of the literature on applications of graph theory in research in education and related disciplines. Applications include order-theoretic studies of the dimensionality of data sets, the investigation of hierarchical structures in various domains, and cluster analysis.…

This book contains volume 1 of the proceedings of the 23rd annual meeting of the International Group for the Psychology of Mathematics Education (PME) held October, 2001 in Snowbird, Utah. Papers include: (1) "Opening the Dimensions of Mathematical Capability: The Development of Knowledge, Practice and Identity in Mathematics Classrooms"…

Describes an exercise for college and high school students that relates descriptive statistics to the regional climatic classification. The exercise introduces students to simple calculations of central tendency and dispersion, the construction and interpretation of scatterplots, and the definition of climatic regions. Forces students to engage…

Methods that have been employed in McGill University's (Montreal, Quebec) program of research into the nature of learning are described. The methods illustrate four phases of inquiry: conceptualization or model-building; data gathering techniques; data representation; and data analysis. For the university's learning task project, the development…

The American Association of University Women (AAUW) sponsored a national survey research project that polled school aged children to study the interaction of self-esteem and education and career aspirations in adolescent girls and boys in today's society. Three thousand children between grades 4 and 10, in 12 locations nationwide, were surveyed.…
