Sponsored by NASA and the JASON Education Foundation, the remote Sensing Earth Science Teacher Education Program (RSESTeP) trains teachers to use state-of-the art remote-sensing technology with the idea that participants bring back what they learn and incorporate it into Earth science lessons using technology. The author's participation in the…

Conventional physics laboratory courses generally include an emphasis on increasing students' ability to carry out data analysis according to scientific practice, in particular, those aspects that relate to measurement uncertainty. This study evaluates the efficacy of the conventional approach by analyzing the understanding of measurement of…

In this article a study is presented in which teachers describe the working situation at their school. The aim of the study was to find out in what respects the school needed to be developed. The study was a case study and the method for collecting data was focus group dialogues. All teacher teams at a Swedish secondary school participated. The…

A new and unified approach to test equating is described that is based on log-linear models for smoothing score distributions and on the kernel method of nonparametric density estimation. The new method contains both linear and standard equipercentile methods as special cases and can handle several important equating data collection designs. An…

Computer task automation is part of the natural progression of encoding information. This thesis considers the automation process to be a question of whether it is possible to automatically learn the encoding based on the behavior of the system to be described. A variety of representation languages are considered, as are means for the learner to…

The Project on State-Level Child Outcomes is designed to assist states and other groups to improve the measurement of child outcomes in state welfare evaluations and in other state data systems. This report summarizes a meeting of the 12 states (California, Connecticut, Florida, Illinois, Indiana, Iowa, Michigan Minnesota, Ohio, Oregon, Vermont,…

This report compares three approaches to descriptive research, focusing on the kinds of descriptions developed and on the methods used to develop the descriptions. The main emphasis in all three approaches is on verbal data. In these approaches the importance of interpretation and its intuitive nature are emphasized. The three approaches, however,…

New estimates are offered for each Southwestern region for 1850, the Southwest as a whole, and the entire United States. (NQ)

The Experimental Ecological Reserves Project has begun a comprehensive attempt to inventory the Nation's environmental research sites in preparation for establishing a network. This network will provide opportunities for long-term, manipulative, ecological research and establish an ecological data base. (BT)

Article provided some recent statistics on educational levels completed by adults 25 and over in 1974 and compared them to those of 1940. (RK)

The main concern of this study was the training of classroom teachers who could promote and sustain inquiry learning with children in elementary schools. (Author)

Will a combination of lecture plus teaching demonstrations produce better learning than when equivalent information is presented through lecture alone? The present field experiment directly addressed this question. (Author)

Questionnaire and interview methods are described as reactive because when these methods are used, the participant's reactions to the research process may influene his or her responses. Nonreactive methodology refers to unobtrusive methods of collecting data in which participant reaction to the process of data collection does not interfere with…

Evaluators, by the nature of their work, must be concerned with data management activities ranging from the collection and recording of data to the analyses, summation, and presentation of those data. Though word processing has been cited as the most frequently used microcomputer package by educational evaluators, spreadsheets are among the most…
