This observational study involving intact groups and convenient sampling examined learning communities at four North Texas Community Colleges. The purpose of this study was to determine if there was a significant difference in cathectic learning climate, inimical ambiance, academic rigor, affiliation and structure among students in learning communities and freestanding classes. Learning communities are gaining nationwide popularity as instruments of reform in Higher Education. Recent studies have discussed the benefits of learning communities to student, faculty and institutions. As learning communities are gaining popularity, especially at the community college level, there is a need to determine if the learning communities are significantly different than freestanding classes. The College Classroom Environment Scales, developed by Winston, Vahala, Nichols, Gillis, Wintrow, and Rome (1989), was used as the survey instrument for this study. Using SPSS 10.1, a multivariate analysis of variance, (Hotelling's T2) was performed on five dependent variables: cathectic learning climate (CLC), inimical ambiance (IA), academic rigor (AR), affiliation (AF), and structure (ST), which yielded a significant difference. The independent variable was learning community compared to freestanding classes (group). Follow-up independent t tests were also conducted to evaluate the differences in the means between the two groups and to explore which dependent variables contributed to the multivariate difference, which resulted in significant differences in inimical ambiance, affiliation and structure. The researcher concludes that learning communities make a difference for some learners, but not necessarily all and that more research needs to be conducted to find the answers to the questions concerning the efficacy and sustainability of learning communities in higher education.

The purpose of the study was to determine the direct influences of selected environmental, academic, and background factors as well as academic outcomes and expression of intent to leave on persistence or non-persistence of nontraditional students at a comprehensive community college in the Dallas County Community College District. The study applied a conceptual model of nontraditional undergraduate student attrition. Data for this study were collected during the Fall, 1987 semester from 312 first-year nontraditional students using the two-year institution questionnaires from the National Center for Higher Education Management Systems. In addition, follow-up surveys were administered to the 97 students who did not re—enroll for the Spring, 1988 semester. The data were analyzed using discriminant function, chi square, and product-moment correlation. For these nontraditional students, educational goal commitment, cumulative grade point average (GPA) and expression of intent to leave at the end of the semester had significant direct influence on persistence or non-persistence decisions. In contrast, environmental factors such as finances, employment status, and family responsibilities, and background factors such as high school academic performance, enrollment status and parents' education level did not directly influence dropout decisions. Nontraditional students reported receiving moderate to high levels of encouragement to remain in college from outside sources, especially employers. In spite of this encouragement, a frequent reason given for leaving college was the inability to cope with working and going to school at the same time. The results generally confirmed that the conceptual model used in this study provided a valid framework for research on nontraditional student attrition. Accurate prediction of persistence or non-persistence of nontraditional students in a community college appears quite difficult due to the heterogeneity of this student population and their diverse educational goals.
