This article reports on a research effort that investigated whether the use of Microcomputer-Based Labs (MBLs), implemented within an inquiry-based activity sequence on phase transformations (melting and freezing), contributes to the development of fourth grade (9-10 year-old) students' conceptual understanding and ability to construct and…

This paper summarizes an experiment conducted to examine the counting performance of 7- and 8-year-olds. Analysis of variance was computed on counting errors produced when enumerating a set of squares on a computer screen. The factors included in the analysis were age, gender, array size, error type, proximity, and error form. The primary…

Noting that understanding how science students respond to anomalous data is essential to understanding knowledge acquisition in science classrooms, this paper presents a detailed analysis of the ways in which scientists and science students respond to anomalous data. The paper postulates seven distinct forms of response to anomalous data: ignoring…

The purpose of this planning study about crafts in the United States is to provide preliminary data and information prior to a national crafts' survey by the National Endowment of the Arts. This study reports on: (1) the preparation of a systematic classification of U.S. crafts; (2) attempts to group and classify crafts people and their…

The use of reporting final examinations in the Netherlands is described. Each October a public report is published by Cito, supplying information about the achieved level of education and describing observed psychometric qualities of the measurement instrument. General information needs are provided by the National Bureau of Statistics. (LMO)

This paper explores the influence of researcher race on data analysis and interpretation, sharing four racially diverse researchers' experiences and struggles as they examined the same set of empirical data. The researchers were part of a larger project at the University of Dayton, the Schools Effects Study, which investigated the urban schools…

Describes tools for measuring content of instruction, content of instructional materials, and alignment between them, reporting findings about use of these tools and possible additional uses for research and practice. Asserts that the validity of data produced using these tools is good. Sketches an agenda for future work to improve the quality and…

Describes classroom activities and shows that statistics is a practical tool for solving real problems. Presents a histogram, a stem plot, and a box plot to compare data involving class enrollments. (YP)

Data on 1993 campus crime from 796 higher education institutions with enrollments over 5,000, required by federal law, reflects a rise in robberies, aggravated assaults, arrests for drug and weapons violations though property crimes and murders decreased. Interpretation of data, seen as providing an incomplete picture, is debated. (MSE)

Focuses on political misrule through the use of statistics. It examines the defining of political events in this century and the reasons for the rise of the statistics-oriented, problem-solving state which, it is argued, has had adverse affects on social programs and antipoverty policies and has created a misunderstanding of the prevalence of…

Addresses the problems related to research design and the improper interpretation of survey results at the institutional level. Analyzes the validity of student opinion surveys. Discusses the importance of response rates. Encourages developmental educators to question results of surveys when outcomes are contrary to the findings of research…

A preliminary survey of formal concepts of "disability" from the Twelve Tables of Rome of the 5th century BCE to the Prerogativa Regis in English law of the late 13th century CE is presented. Firm conclusions are restricted by problems in translation and other limitations in available data. However, it appears that the concept of…

This paper focuses on model interpretation issues and employs a geometric approach to compare the potential value of using the Grade of Membership (GoM) model in representing population heterogeneity. We consider population heterogeneity manifolds generated by letting subject specific parameters vary over their natural range, while keeping other…

Recent national survey results underscore the importance of economic and financial education: It appears that many Americans are making poor financial choices in such basic areas as saving for long-term goals and managing personal credit. Social studies teachers need to reexamine the contribution that the social studies curriculum can make in…

The reading, analyzing and critiquing of primary literature in both writing and oral forms are daunting tasks for science undergraduates. These activities are recognized as skills that science undergraduates should develop in order to improve their scientific communication abilities.
