We develop an Easy Java Simulation (EJS) model for students to experience the physics of idealized one-dimensional collision carts. The physics model is described and simulated by both continuous dynamics and discrete transition during collision. In designing the simulations, we discuss briefly three pedagogical considerations namely (1) a…

Teaching students to collect data to answer questions is an important life skill that will serve them well throughout their adult lives. The purpose of this manuscript is to describe the implementation of an action research project in a fifth grade resource classroom. Students with mild disabilities were taught how to conduct surveys using three…

The "Condition of Education" is an annual statistical report about education in the United States. This review describes and comments on the publication's data selection data presentation, prose interpretation, and the quality of the statistics. Options for improving the publication are discussed.

This article adopts "citation approach" to distinguish interdisciplinary or multidisciplinary research (IDR) from monodisciplinary research and begins to descrie how IDR differs from other research. Ten-year citation histories were constructed for sample of 1981 "citation classics" (over-cited articles) and examined for…

Describes how library decision-making was enhanced by a systematic study of patrons, services, and effectiveness based on the concept known as performance measures for public libraries. Improvements in the data gathering and analysis techniques are noted; also provided are survey instruments, examples of selected revised forms, and references. (SW)

Quick power estimates for detecting a difference in two population proportions are expedient during early stages of research planning. Such estimates are tabled and graphed in this article. They are shown to be conservative but accurate for most research situations when proportions fall in the range of 0.25 to 0.75. (SLD)

The processes used by State Education Agencies (SEAs) to develop capacity for gaining access to information resources and for linking such resources to the needs of educators are described by studying SEAs that have received capacity building grants. Included are an overview of the evaluation, purposes of the study, framework, evaluation…

Describes study of chemists in the Chemistry Division, Organic Research Laboratory, Eastman Kodak Company, as end-user searchers on the DIALOG system searching primarily the "Chemical Abstracts" database. Training, level of use, online browsing, types of searches, satisfaction, costs, and value of end-user searching are highlighted.…

Graphical representation of statistical data is the focus of this resource handbook. Only graphs which present numerical information are discussed. Activities involving the making, interpreting, and use of various types of graphs and tables are included. Sections are also included which discuss statistical terms, normal distribution and…

Reviews a survey of all Ministries of Education and a sampling of school districts taken to explore whether a French Immersion (FI) teacher shortage exists. Findings indicate a stabilization in the growth rate of immersion programs, a lack of teachers for specialty areas and of teachers specifically trained to teach in immersion. (12 references)…

Suggests activities which use newspapers as a source of data from which students design, read, and use tables, charts, and graphs. The activities, in reproducible worksheet format, provide teachers with both short- and long-term projects. (PK)

Described are computer assisted instruction exercises designed by a college professor to help undergraduate psychology students acquire fundamental skills in data collection--recording the data, using tables and graphs, and recognizing functional relationships. (RM)

Examines the process of consonant cluster reduction in the English of residents of a San Antonio, Texas, "barrio." The author compares Tejano patterns of "/-t,d/" deletion with the pan-English pattern. Results suggest a pattern of convergence and divergence. The study shows that Mexican American English exhibits regional and…

Multifaceted Rasch analysis was used to determine whether bias was evident in the way a group of raters graded two different versions of an oral interaction test, undertaken by the same candidates. Results indicate that certain raters consistently rated the tape version of the test more harshly while others rated the live one more harshly. (10…

A description of the background and procedure of this pilot study precedes the data charts and sample forms that make up the majority of the report. Questionnaires gathered information from 304 representative schools on languages studied, grades in which they were studied, and number of credits earned, for each student. Schools are classified by…
