This paper reports on the use of teacher-written "cases" as evaluation data sources. Cases are first hand, candid, dramatic, highly readable accounts of events or a series of events in teaching. Eight teaching cases were collected which had been written by new teachers who graduated from the Maryland Collaborative for Teacher Preparation…

This report describes research that Mathematica Policy Research, Inc. (MPR) has conducted for the U.S. Department of Agriculture (USDA), Food and Nutrition Service (FNS), to develop methods to track the use of "competitive foods" in schools over time. Competitive foods are foods from a la carte cafeteria sales, vending machines, school stores,…

Assesses techniques used by researchers to collect and analyze data on how people with visual impairments or blindness learn, understand, and think about geographic space. Recommendations are made for increasing the validity of studies, including the use of multiple, mutually supportive tests; larger samples; and real-world environments.…

Examines the politics that arise in the research and evaluation of school reform efforts, drawing on qualitative data from a study of comprehensive school reform to elucidate methodological issues in several areas; discussing how the researchers were perceived, how participants used researchers' research and presence in political ways, and how…

Because the researcher's interpretation is the final word, traditional research reinforces relations of domination. When popular theater is used as research methodology, the interviewer's interpretation is performed immediately following data collection, and interviewees offer their interpretations of the interpretation. This gives voice to those…

Identifies cognitive strategies used during the categorization of qualitative data and investigates how various factors may be related to the testimonial validity of the categories. Essay writers ranked sets of categories in terms of overall quality and rated them while thinking aloud. Think-aloud protocols for the "best" and…

A high school sophomore describes his summer job at the Smithsonian National Air and Space Museum where he worked when a rock found in Antarctica was determined to have come from Mars. He identifies with the enthusiasm of preteen day-campers for scientific learning and is flabbergasted by the nonchalant reactions from scientists to the possibility…

Discusses a graphical analysis method used in the physics laboratory. Shown are various kinds of graphs to illustrate the relationship between two variables. A procedure for deriving equations from laboratory data is described. (YP)

Multidimensional scaling (MDS) and its potential use for research and evaluation in health-related professions are discussed. Useful data types, interpretation of results, and various applications of MDS are presented. MDS is less restrictive than factor analysis since it does not assume a linear relationship between the objects/variables of…

Argues about the conclusion that bigger science departments are more productive than smaller ones. Indicates the conclusion cannot be supported by the data. (YP)

Recommends a revision of the traditional method for teaching history, so that students view facts as the starting point, from which they learn to classify, examine, and evaluate historical events. Suggests activities and projects for implementation of this teaching method. (LS)

Describes a class demonstration of observer bias in which students were led to believe what the research data would indicate. Reports that students reported trends consistent with the expectancy. Asserts that the demonstration had a strong and memorable effect on students and has value for demonstrating observer bias. (CFR)

The Assessment of Performance Unit recognized the importance of reading and interpreting data but saw them as discrete aspects of "process" science. However, pupil performance on different components of the same data-handling assessment question is often very variable, indicating that these questions carry "hidden" cognitive…

This article provides ideas on how to conduct alumni telephone surveys: (1) use the information gathered; (2) implement a survey; (3) develop appropriate questions; (4) test a survey instrument; (5) train interviewers; (6) collect the data; (7) analyze the results; (8) report the results; and (9) use the results to take action. (MDM)

This article provides advice on how to plan and conduct an alumni census through the mail, drawing on the experiences of Stonehill College in North Easton, Massachusetts, which undertook such a survey in 1992. It focuses on costs, information needs, questionnaire design, mailing considerations, reporting the results, and expected response rates.…
