Describes three classes of measurement techniques: (1) interviewing methods; (2) record retrieval procedures; and (3) observation methods. Discusses primary reasons for measurement error. Concludes that, although measurement error can be defined and controlled for, there are other design factors that also must be considered. (CFR)

Reports five experiments; the first two assessed the effect of the selectional restriction requirements of verbs and the animacy of nouns on sentence comprehension, the third determined the cause of the interaction found in the first set of studies, and the fourth and fifth were self-paced reading experiments.

Argues that the choice of method for constructing concepts such as family and household does matter but that there is no a priori link between method and construction or between method and epistemological position. The extent of overlap between constructs produced by different methods must be investigated rather than assumed. (LKS)

Examines the accuracy of the current public attitude that instruction in English as a Second Language (ESL) at the college level is too expensive, and that nonnative students' success is not commensurate with the cost of teaching them. The article argues that these students represent the country's future and that educators must counter the assault…

An overview is presented on action research and practical inquiry, with attention to the initial phase of starting this approach, gathering data, analyzing the results, sharing findings, and judging the quality of action research and practical inquiry. Gifted education practitioners are encouraged to share action research findings. (SW)

This chapter gives an overview of the design and statistical and psychometric analysis methods of the National Assessment of Educational Progress (NAEP). The evolution of the NAEP continues to provide challenges to statisticians and psychometricians, as demonstrated in the expansion of the NAEP to the assessment of individual states. (SLD)

Following previous reports, this paper contains additional information about the multilingual situation in the multiethnic town of Bukavu in Zaire. Focus is on codeswitching, an important characteristic of the overall dynamic picture of linguistic interaction. Myers-Scotton's markedness model is discussed. (13 references) (Author/LB)

The acquisition of German in three adult Poles over a three-year period is examined based on an acquisition profile of each person that specified the sequences in acquisition. The findings suggest that cognitive factors must be considered to explain the varying degree of success in the acquisition process. (40 references) (Author/LB)

Outlines what school administrators can do to increase their understanding of local dropout programs and to decrease dropping out. Suggestions include analyzing local data, instituting early tracking of potential at-risk students, creating alternative programs, reorganizing to improve school climate, and initiating new forms of student assessment.…

Presents an outdoor experiment to measure the speed of sound as a classroom experience to begin the teaching year. Measures the delay time from seeing and hearing crashing cymbals across a field to calculate the speed. Exposes students to experimental uncertainties and limits of uncertainty in measurement. (MDH)

Suggests using simulated data to teach students about the nature and use of statistical tests and measures. Observes that simulated data contains built-in pure relationships with no poor response rates or coding or sampling errors. Recommends suitable software. Includes information on using data sets, demonstrating statistical principles, and…

Reviewed are the various purposes that discussion may serve for science education--for carrying out practical work, for interpreting results, and for understanding social issues. The importance of students contributing their own experiences to a discussion is discussed. (KR)

Investigations that facilitate experimental design, the concept of replication, data analysis, and other aspects of scientific study are described. A list of materials, the recommended plants, and the directions for building the hydroponics unit are included. (KR)

Describes a project developed at the Northern Virginia office of Central Michigan University (CMU) to analyze reference questions received at an off-campus library services program for graduate students. The development and use of a software program--the Statistical Package for the Social Sciences SPSS/PC+ Studentware--is explained. (LRW)

Describes a take-home experiment in which students measure the diffusion of acid through acid-filled capillary tubes immersed into base solutions and vice versa. Students represent and analyze the effects of ambient temperature, molecular weight, and concentrations of the solutions on that movement. (MDH)
