大學環境 尺度의 妥當化를 위한 分析硏究 = The Identification, Measurement, and Diagnosis of College Environment

다국어 초록 (Multilingual Abstract)

The purpose of this study were threefold. First, the study attempted to explore the dimensionality of college environment and, especially, formulated conceptual framework concerning the college environmeint. Second, it involved the identification and measurement of the college environment based on its conceptual framework. Finally the major purpose of the study was aimed at establishing the construct validity regarding the instrument of assessing college environment.
Instrument for assessing college environment was developed and tested using analysis of various validation procedures for exploratory procedures and confirmatory test procedures. Especially, the confirmatory test procedures included reliability and factor analysis.
The main study was carried out throughout the nation and 3253 males and females were used. In order to select items for inclusion in these scales, item analysis was performed. An adjusted item-total correlation was completed for each item. An item-total correlation is a correlation of an individual item with the total scale score. It is adjusted to remove the bias of adding that item score to the total with which it is being correlated. The adjusted item-total correlation is an index of degree to which the item is measuring the same dimension as the total score.
The estimate of reliability for the subscale was all high. The estimate for the college environment instrument ranged from .46 to .80 respectively. From this evidence, it was possible to conclude that the instrument has such a small error of measurement that they could be meaningfully in the next phase of the analysis.
Factor analysis of inter-correlation of items of the instrument followed by oblique (promax) solutions. Criteria were formulated to determine the degree of correspondence between empirical (rotated) factors and the parallel a priori dimension; (1) if within a given a priori dimension at Beast 80 to 90 percent of the variables for each scale exhibited their maximum loadings on this one empirical factor alone, (2) if the loadings on the empirical factor within the given a priori domain were equal to or greater that .30. The results based on the above criteria showed that there was empirical evidence for considering the subscale of the college environment as unifactorial. Thus, it could be concluded that each of the scales was accepted as representing a good fit to onefactor model.
The significance of the present study was theoretical, methodological and practical. It's theoretical significance stemed from conceptualization of college environment. Thus, the present investigation contributed to an understanding of college environment. The methodological significance of the study lied in the approach to be utilized. The present
stud!'presents a potentially highly useful way of using and measuring college environment. The practical significance of the present study lied in the development of a specific instrument for the measurement of the practical aspects of the college environment. The development of an instrument for the measurement of such variables provides the opportunity for diagnosing college environment for the purpose of identifying deficiencies in it.
