Investigates consumer research through an activity that helps students distinguish between qualitative and quantitative data. (KHR)

Describes the Goldstone Apple Valley Radio Telescope (GAVRT) project as a way of teaching astronomy concepts to middle school students. The project provides students opportunities to work with professional scientists. (SOE)

Examined the utility of general growth mixture modeling (GGMM) for evaluating early childhood education programs. Initially, growth mixture modeling procedures identified two growth patterns among Head Start children. However, GGMM procedures found that children with at least 2 years program participation did not have faster achievement growth…

Used a dynamic systems (DS) approach to study changes in structure of family interactions in problem-solving sessions during the early adolescent transition of boys in 149 families. Constructed state space grids (a new DS method) for families across five waves of videotaped data collection before, during, and after the transition. Found that DS…

Investigates the structure of information in all sections of the medical research paper. Findings identify an eleven-move schema, out of which nine were found to be "normally required" and two "optional." Each schema was found to embody "constituent elements" and to be characterized by distinct linguistic features. (36 references) (Author/CK)

Defines terrestrial and Jovian planets and provides directions to obtain planetary data from the National Space Science Data Center Web sites. Provides "number-crunching" activities for the terrestrial planets using Texas Instruments TI-83 graphing calculators: computing volumetric mean radius and volume, density, ellipticity, speed,…

Explores the nature of human inquiry groups and how such groups decide on a research agenda. Outlines the stages involved in the process and considers the value of human inquiry as a qualitative methodology for counseling research. Compares the roles of the human inquiry researcher and the counselor. (RJM)

Argues that an earlier assessment of a racial identity scale was appropriate. Claims that "possible failures" of the analysis were addressed in the study and confirms that the complex patterns expected from the racial identity measure do not exist in the data. Other results, along with implications for counseling research, are discussed.…

This 3-year longitudinal study examined depressed affect during early adolescence. Variable-centered analyses yielded general stability in depressed affect for both boys and girls. Person-centered analysis revealed five patterns of depressed affect, with gender differences only in smaller subgroups that showed patterns of change in depressed…

Describes how probability is treated in the National Council of Teachers of Mathematics' (NCTM) "Principles and Standards of School Mathematics". (YDS)

Guides students through the process of designing a window. Allows them to use technology and a variety of representations while maximizing and minimizing the dimensions based on cost and light. Includes activity sheets. (Author/NB)

Offers an overview of the authors' experience using several observational methods to better understand one class of users, expert clinicians treating patients in hospital settings. Shows the evolution of understanding of the users and their information-handling tasks based on observations made in the field by a multidisciplinary research team, and…

Provides methods for the systematic redesign of a library Web site through comparing baseline data changes in use brought about by design changes. Shows how complementary information, based on Web users' log statistics and direct observations of users, can enhance a library Web site. Relates this information to practical Web site decisions that…

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)

This study examines the impact of school structures on potential dropouts. Data from field notes, interviews, and school records are used to describe and discuss the effectiveness of interventions generated by a school committee which worked to prevent at-risk students from dropping out of high school.
