The purpose of this study was to develop an instrument to measure the sense of competence of traditional age college students across the dimensions that define the construct. The Sense of Competence Scale-Revised (SCS-R) was developed to provide a measure of Chickering’s (1969) first vector, an important psychosocial construct. Administrators can use data from the instrument to modify an institution’s academic and social environment to enhance the development of the intellectual, physical, and interpersonal competencies of college students. During the development and validation, various aspects of the SCS-R were examined in accordance with the validity framework outlined by Messick (1995). According to Messick (1995), the validity of measures can be examined in terms of six forms of evidence; content, substantive, structural, generalizability, external and consequential. The six forms of evidence function as general standards for all educational measurement (Messick, 1995). During the study the content aspect of validity was addressed through the creation of concept maps and test blueprints. In addition, the content aspect of validity was addressed by creating and selecting items by reviewing the literature and hosting brainstorming sessions, items were then reviewed by student development theory experts, pilot tested, field tested and then items with high technical quality were selected for the final instrument. The substantive aspect of validity was addressed through an analysis of item rating scale functioning, person fit to the measurement scales, and item difficulty. The structural aspect of validity was addressed by evidence of the instrument’s dimensionality. The generalizability aspect of validity was addressed through an analysis of item/person reliability. The evidence generated from the study suggested that the chosen items for the SCS-R provide reliable and valid estimates of a student’ s personal assessment of their intellectual, physical and interpersonal abilities. / Ph.

International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Caterpillar has for many years used telemetry as a key component in the data acquisition and analysis systems used to test and develop heavy equipment. The testing of construction and mining equipment at Caterpillar presents several unique challenges, such as the operating environment of the test machine, the large number of models in the product line, the need to change test machines on a daily basis, and the need to test machines at job sites throughout North America. These challenges have resulted in the development of telemetry, data acquisition and data analysis systems that have been highly customized to meet all of our requirements for construction equipment testing. This paper describes the past history of telemetry use at Caterpillar, from early FM/FM systems to our current PC/Unix based PCM/FM system, the criteria used to develop these systems, and how our current telemetry system is being used today to help develop and test product.

A reliable music store should carry a wide selection of guitars for you to choose from. Ask your teacher which brands he would suggest. You might also ask him to help select a guitar for you. You do not need an expensive instrument in the beginning. Choose a guitar that feels comfortable to you. Do not choose one that is too large for you to hold correctly.
