Describes the construction of an inexpensive light sensor that can be used to measure irradiance in aquatic habitats. Includes a list of tools and materials, details of construction, and usage of the light sensor. (DDR)

The Nature Conservancy's Berkshire Program involves community volunteers in monitoring migration routes of amphibians that rely on vernal pools for breeding success. Vernal-pool workshops provide basic knowledge of amphibian lifecycles and detailed monitoring instructions. Nighttime field trips for adults and children and monitoring experiences…

Documents use of informant-made video (IMV) recordings as a data collecting method for research into adults' art viewing experiences. Compares 10 informants' videotaped accounts of their responses to works of art with audiotaped responses. Reveals that IMVs provided additional information, such as visual documentation of artwork. Concludes with a…

Highlights the development of a data management system to facilitate service delivery by the career planning and placement department at the University of Michigan-Ann Arbor. Recounts the development of the system, providing the context for data management and describing the issues associated with building and implementing a data model, and the…

Discusses the wide array of variables and possible research approaches and techniques that need to be considered in conducting research that investigates the linguistic impact of the study abroad experience. Offers a framework that evaluates, assesses, and ensures the effectiveness of study abroad and also integrates and interprets the diversity…

Describes an activity that combines learning and assessment of students' measurement skills. Students strive to make measurements accurately and precisely at a series of stations that focus on measuring length, volume, and mass. (DDR)

Presents a framework to describe typical constraints that program evaluators face. The framework encompasses the usual evaluation costs and other factors that impede data collection or the implementation of strong evaluation designs. These are characterized as internal/substantive or external/political. (SLD)

A Utah district's assessment committee created an innovative, yet conservative teacher-evaluation program using direct measures of teacher performance. Teachers can choose among various data sources: parent surveys, student surveys, student-achievement data, documentation of professional activity, and teacher tests. Datasets are preferred over…

Good reforms can have harmful results if equity effects are ignored. As California implements its accountability system, certain questions must be addressed concerning the system's data use, measurement features (consistency, meaningfulness, achievement growth, achievement gaps among groups), instructional improvement focus, incentives for…

To understand how a school uses technology, administrators should examine various data on students' computer skill development; staff development records; student anecdotes; lab logs; technology use plans; and software-acquisition, repair, and budget records. Technology implementation should mirror different classroom and subject-area needs and…

With many information retrieval (IR) schemes available, researchers have begun to investigate the benefits of combining results of different IR schemes to improve performance, in the process called "data fusion." This article investigates the predictive power of two variables--similarity of efficacy and dissimilarity of outputs--in simple…

Apparel merchandising students participated in a cooperative research project in which they observed customer service techniques by posing as customers in retail stores. The project taught research processes, collaboration, and principles of customer service. (SK)

This two-part article combines a comprehensive account of a probabilistic model of retrieval with new systematic experiments on TREC (Text Retrieval Conferences) Program material. Part 1 covers the foundations and the model development for document collection and relevance data, along with the test apparatus. Data and results tables for both parts…

A comprehensive account of a probabilistic model of retrieval with new systematic experiments on TREC (Text Retrieval Conferences) Program material. Part 2 covers the further development of the model, with testing, and briefly considers other environment conditions and tasks, model training, concluding with comparisons with other approaches and an…

Describes the Common Core of Data (CCD) program as a good example of effective collaboration between local, state, and federal levels of government. Identifies some recently discussed issues regarding the usefulness of CCD information for education policies, including the reliability, consistency, and flexibility of data. (SLD)
