The objective of this study was to gather information about and assess the accessibility, use, and perceived needs toward computing technologies of elementary, middle school and high school science teachers in two large rural school districts. A questionnaire of over 500 items, Survey of Usages of Computing Technologies in Science and Mathematics Teaching, was designed and developed. Attitude and belief items were developed or modified from previous assessment instruments for science, mathematics, and other disciplines. Responses were received from 122 elementary school teachers (a 60% return rate) and 30 middle school and high school teachers (a 70% return rate). Information was collected on the following topics: (1) availability of computers; (2) level and types of computer use; (3) beliefs about computer use; and (4) current conditions and conditions needed or desired for using computing. All respondents reported having basic computer skills; 72% reported intermediate skills. Fifty-one percent of the elementary teachers agreed that computers would improve science instruction; however, 63% of the middle and high school teachers believed that computers would not improve science instruction.
