This paper describes the role of data and task context in young children's interpretation of and reasoning about data tables. A design-based descriptive study was conducted with fourteen 5-year-old children in their first year of formal schooling. A picture storybook provided the data context for a data modelling activity that focused on…

The need for data literacy is an increasingly pressing priority in society, but most of the work in data-centred education has focused on developing skills at the middle school, secondary, and post-secondary levels, with little attention on the potential for engaging elementary-aged students in reasoning with and about data. This paper reports…

Quantitative and statistical literacy are core domains in the undergraduate psychology curriculum. An important component of such literacy includes interpretation of visual aids, such as tables containing results from statistical analyses. This article presents results of a quasi-experimental study with longitudinal follow-up that tested the…

In introductory statistics courses, the concept of power is usually presented in the context of testing hypotheses about the population mean. We instead propose an exercise that uses a binomial probability table to introduce the idea of power in the context of testing a population proportion. (Contains 2 tables, and 2 figures.)

This article focuses on the notion of literacy--general and statistical--in the analysis of data from a fieldwork research project carried out as part of a master's degree that investigated the teaching and learning of statistics in adult education mathematics classes. We describe the statistical context of the project that involved the…

This study evaluates the effects of an intervention aimed at improving representational flexibility in linear-function problems. Forty-nine students aged 13-16 participated in the study. A pretest-intervention-posttest design with an experimental and control group was used. At pretest, both groups solved a choice test, where they could freely…

This study reports from a pre-service teacher's online learning and assessment activity on determining variability of two graphical artefacts. Using a critical-analytical perspective to data, the present study indicates that the prospective teachers surveyed showed awareness of relevant subject specific operators and methods; however, these seem…

This paper presents an alternative version of formulas of conditional probabilities and Bayes' rule that demonstrate how the truth table of elementary mathematical logic applies to the derivations of the conditional probabilities of various complex, compound statements. This new approach is used to calculate the prior and posterior probabilities…

Findings from the ninth triennial administration of the National Survey of First-Year Seminars, describing the nature and extent of first-year seminars on American college campuses. Drawn from a broad sample of colleges and universities from every institutional type, control, and size, the survey addresses topics including seminar characteristics…

This study investigated the degree to which seventh- and eighth-grade students of different abilities acquired strategic planning knowledge from a problem-solving computer game called Wumpus. Regression analysis was used to determine the influences of individual differences and either activating or modeling instruction, and to assess transfer of…

Presents steps taken by a librarian task force at Washington State University in planning, implementing, and evaluating the addition of LEXIS-NEXIS workstations; user policies; and instruction methods in an academic reference environment. Figures and tables display: workstation information including usage statistics, an outline of the Lexis-Nexis…

Statistical data can be represented in a number of qualitatively different ways, the choice depending on the following three conditions: the concepts to be investigated; the nature of the data; and the purpose for which they were collected. This paper begins by setting out frameworks that describe the nature of statistical thinking in schools, and…

The current status of education for 1999 is presented as an indicator report, analyzing key data that measure the health of education, monitor important developments, and show trends in major aspects of education. Each year, about 60 indicators are selected that represent a consensus of professional judgment on the most significant national…
