Agricultural information staffs at land‐grant universities are charged with disseminating information to the general public in order to arouse interest in and understanding of agricultural research and extension programs. The following study indicates that the television newscast is a good outlet for at least some of this information; one that economically can be used by agricultural information staffs. Joseph J. Marks is Director of Agricultural Information for Michigan State University. This article is based upon his M.A. thesis in the Department of Television and Radio at MSU, which was completed under the direction of Dr. Thorns F. Baldwin. 相似文献

Reliability can be estimated using structural equation modeling (SEM). Two potential problems with this approach are that estimates may be unstable with small sample sizes and biased with misspecified models. A Monte Carlo study was conducted to investigate the quality of SEM estimates of reliability by themselves and relative to coefficient alpha. The SEM approach showed minimal bias when the model was correctly specified if items were relatively well defined by their underlying factor(s). They tended to demonstrate somewhat greater bias when the model was misspecified, particularly underspecified. Overall, SEM estimates were more stable than anticipated. Researchers are more likely to obtain accurate estimates of reliability using SEM by conducting large-sample studies with well-constructed scales and critically assessing model fit. 相似文献

This article examines ad valorem tax rates per $100 valuation and the resultant tax revenues per in-district contact hour for Texas nonmetropolitan and metropolitan public community colleges. The results of the analyses indicate no difference in ad valorem tax rates between these institutions but demonstrate differences in the resultant tax revenues. Recommendations for further research are provided. 相似文献

This article describes a framework for the comprehensive evaluation of counseling programs and functions within the community college, using Astin's student success conceptualization. Some evaluative results using this framework are included. With such a framework, counselors can clearly show their contributions to the community college and the students they serve. The topic of counselors as sources of pertinent information about campus students in general is also discussed. 相似文献

White undergraduate students enrolled in introductory statistics courses completed the Survey of Attitudes Toward Statistics (SATS). Student responses were analyzed using confirmatory factor analysis to determine the validity of several alternative models of the structure of attitudes toward statistics. A four‐factor structure composed of Affect, Cognitive Competence, Value, and Difficulty provided the best model fit. Responses of women and men to the SATS were then examined to explore scale invariance across gender. Invariance tests of factor structure, factor‐variable correlations, factor correlations, and variable uniquenesses showed that the four‐factor model fit well for both female and male responses. Only two significant differences in model fit were found: the Value variance was greater for women and the correlation between Affect and Value was greater for men. Generally, the study provided evidence for the appropriateness of a four‐factor structure of the SATS. 相似文献

The purpose of this study was to develop a better understanding of why college students seek psychological treatment by examining indicators of psychological distress. A secondary goal was to assess the utility of screening for treatment need via a brief self‐report measure of distress. Two samples (1 clinical, 1 nonclinical; N= 8,380) were examined via logistic regression analyses to identify meaningful predictors of treatment‐seeking behavior. Clinical applications are discussed. 相似文献

This article investigates the use of the contextual orientation to the Bible—which seeks to understand the Bible as a product of its time, and in the context of historical-critical biblical scholarship—as a deliberate, significant aspect of a teacher's overall approach to reaching Jewish adults in their 20s and 30s. Through classroom observation and qualitative interviews, the authors (one of whom is the teacher in the article) explore how this approach affects student learning and engagement and facilitates a meaningful attachment to and understanding of the Bible. This article also reflects one teacher's examination of his own teaching orientation and its expressions, serving as a possible model for other such investigations. 相似文献
