This exploratory study investigated the crucial role society and individual college cultures played in selecting and channeling women from male-dominated to female-dominated majors. Since academic major is linked to the kind of vocation a person pursues, scarcity of women in certain majors constitutes an obstacle to opportunity in the work force. Literature was used to develop questions for interview protocol to identify reasons for college women's decision to leave a male-dominated major and enter a female-dominated major. The interviews provided self-report information from college women transfers from the College of Engineering, College of Business, and College of Architecture to the College of Human Resources and revealed six factors that explained their decisions. These factors were classroom environment, faculty behaviors, peer relations, curriculum content, performance pressures, and role expectations. These factors were interdependent though each played a significant role in explaining the women's decisions. Additionally, women's decision to leave a male-dominated major and enter a female-dominated major was a function of affirmation of self and was derived from the six environmental factors. The degree of interaction congruence between the student and each of these factors affected affirmation of self and how women evaluated and responded to their environment. Lastly, applications for educational practitioners were offered and recommendations for further research were suggested. / Master of Arts

In this thesis the author has conscientiously attempted to portray in clear fashion the status of all V.P.I. graduates, post graduates, and those qualified to teach in vocational agriculture since 1918. The material collected, it is hoped, will serve as a source of information for professors at V.P.I. who have to do with guidance and placement. Furthermore, it is expected that the information contained herein, will show certain pertinent facts concerning the department of vocational education in question. Is the department efficient? Do its graduates secure jobs? Are salaries commensurate with time spent in securing degrees? Does the higher degree have any significance so far as increase in salary or steps in advancement are concerned? Have the V.P.I. graduates obtained positions of unusual responsibility and honor? Has service rendered by these graduates been hit or miss, or has it been constructive and definite over a long period of time? What has been the percentage of V.P.I. agricultural men who have entered occupations allied to farming? Are there any facts which indicate success n these allied occupations? Such questions as the above, and others, are answered in this thesis. In attempting to collect the information mentioned above the author has made use of the Alumni Office files; the records in offices of the various supervisors of Agricultural Education - Dr. W.S. Newman, State Board of Education, Richmond, Va.; Mr. D.J. Howard, Assistant State Supervisor, Winchester, Va.; Mr. T.V. Downing, District Supervisor, Ivor, Va.; Mr. J.O. Hoge, District Supervisor, Blacksburg, Va.; Mr. F.B. Cale, District Supervisor, Appomattox, Va.; department files; Alumni files; Registrar's office; Cormier's thesis and questionnaires. Grateful acknowledgment is made to these men as well as to Professors E.C. Magill, H.C. Groseclose, H.W. Sanders, and other school officials who have rendered valuable assistance in the arduous task of preparing this thesis. / Master of Science

The Environmental Protection Agency estimates that numerous lung cancer deaths result every year due to radon exposure. Given this, radon education has become an important issue. The purpose of this research was to examine what action consumers had taken to respond to radon as a hazard following an education testing program and why they had taken that action. In the Fall of 1992, the Virginia citizens Consumer Council, in partnership with Virginia Cooperative Extension, conducted a radon education campaign to promote and sell radon test kits. This study is based on a follow-up telephone survey in which 100 Virginia consumers whose homes tested with high radon levels were asked what action they had taken to reduce their radon exposure. Using a proportional allocation, a sample was drawn from eight Virginia counties. statistical analysis included the use of cross tabulation tables and testing for association through the use of the gamma function. Statistically significant findings included: 1) objective risk does have an impact of hazard response; and 2) a correlation was found between how worried consumers were about their radon problem and their response to the hazard. / Master of Science

The purpose of this study was to analyze the reliability and validity of three achievement tests, with emphasis given to instructional validity. The tests were used to assess the performance of Business Computer Applications (BCA) students on their achievement of knowledge of computer application software concepts and vocabulary for word processing, spreadsheet, and database. Five concepts and vocabulary categories addressed included: vocabulary, access software, data/text entry, editing, and formatting. Data were also collected from BCA teachers of the students. Teachers were asked to rate each item for the three software types of the achievement test as to whether the concepts and vocabulary corresponding to that item had been taught. A selected sample was used in the study. Classes were divided into three approximately even student groups. Each group completed one of the tests for each software type. Percentage of items correct for the three software types were 53%-word processing, 46%- spreadsheet, and 36%-database. The Kuder-Richardson 20 (KR-20) estimates for the software types were .92--word processing, .92--spreadsheet, and .76--database. Due to a wide dispersion of KR-20 values for items within the 5 concepts and vocabulary categories by software, the items are useful only for group measures. Most of the 8 teachers did not teach a substantial part of the concepts and vocabulary included in the validated test items. This outcome indicates the curriculum related to the items needs to be examined and revised so that teachers can emphasize the most important concepts and vocabulary with their students. Analyses outcomes indicated that 59 of 60 word processing items, 51 of the 59 spreadsheet items, and 45 of the 59 database items were instructionally valid. Teachers selecting items for purposes of examining the achievement of their students related to software concepts and vocabulary cam effectively use items determined to be instructionally valid in this study. / Ph.
