Research in music education
A "survey" is a systematic method of collecting information on one or more variables. An example of a survey study is a 1998 study by Gillespie and Hamann. The purpose of the study was to gather descriptive information about orchestra programs that can be used as baseline data when considering the needs of school string programs. The findings indicated a continued enrollment increase in school orchestras in the 1990s although the number of orchestra teachers remained stable, and that larger schools are more likely to offer orchestra instruction. The impact of the study was the recommendation that school systems should provide larger, more adequate teaching facilities and that universities and string teachers should emphasize strategies for teaching larger string classes in their teacher preparation programs.
Astronomical survey
An astronomical survey is a general map or image of a region of the sky which lacks a specific observational target. Alternatively, an astronomical survey may comprise a set of many images or spectra of objects which share a common type or feature. Surveys are often restricted to one band of the electromagnetic spectrum due to instrumental limitations, although multiwavelength surveys can be made by using multiple detectors, each sensitive to a different bandwidth.
