The process of mentorship in relationship to the community college professor and the potential to improve and enhance the teaching and learning process is explored in this article. This article suggests that not all community college professors are psychological or intellectually disposed to being or becoming a good mentor. It is put forth that mentoring is a subrole of the community college professor. A framework for understanding the “complete mentor” process, as developed by Cohen (1993), is presented. Implications for practice are offered in a manner that connects the community college professor as mentor with enhancing the instructional process through the nurturing teaching perspective. 相似文献

ABSTRACTThis paper investigates community college transfer success by exploring the relationship between individual and institutional-level characteristics at students’ two- and four-year institutions. Using statewide administrative data from North Carolina, this study employs a cross-classified multilevel model to investigate the impact that a student’s community college and four-year transfer institution have on post-transfer success. Our findings offer important and compelling insights into the relationship between transfer students, the community college they attended, the four-year transfer institution, and educational outcomes. While individual effects were small, we find several institutional factors associated with student success. Attendance at a large community college or having a public university in the same county as their community college is positively associated with student success, whereas size of the university is negatively related to grades during the first year and persistence to the second year. While the four-year institution’s selectivity is negatively related to many of our outcomes, transferring to a Historically Black College or University is positively associated with GPA, college persistence, and degree completion. 相似文献

Two Lagrange multiplier (LM) methods may be used in specification searches for adding parameters to models: one based on univariate LM tests and respecification of the model (LM‐respecified method) and the other based on a partitioning of multivariate LM tests (LM‐incremental method). These methods may result in extraneous parameters being included in models due to either sampling error or the model being misspecified. A 2‐stage specification search may be used to reduce errors due to misspecification. In the 1st stage, parameters are added to models based on LM tests to maximize fit. Second, parameters added in the 1st stage are deleted if they are no longer necessary to maintain model fit. Illustrations are presented to demonstrate that errors due to misspecification occur with the LM‐respecified method and are even more likely with the LM‐incremental approach. These illustrations also show how the deletion stage can help eliminate some of these errors. 相似文献

We highlight critical conceptual and statistical issues and how to resolve them in conducting Satorra–Bentler (SB) scaled difference chi-square tests. Concerning the original (Satorra & Bentler, 2001) and new (Satorra & Bentler, 2010) scaled difference tests, a fundamental difference exists in how to compute properly a model's scaling correction factor (c), depending on the particular structural equation modeling software used. Because of how LISREL 8 defines the SB scaled chi-square, LISREL users should compute c for each model by dividing the model's normal theory weighted least-squares (NTWLS) chi-square by its SB chi-square, to recover c accurately with both tests. EQS and Mplus users, in contrast, should divide the model's maximum likelihood (ML) chi-square by its SB chi-square to recover c. Because ML estimation does not minimize the NTWLS chi-square, however, it can produce a negative difference in nested NTWLS chi-square values. Thus, we recommend the standard practice of testing the scaled difference in ML chi-square values for models M 1 and M 0 (after properly recovering c for each model), to avoid an inadmissible test numerator. We illustrate the difference in computations across software programs for the original and new scaled tests and provide LISREL, EQS, and Mplus syntax in both single- and multiple-group form for specifying the model M 10 that is involved in the new test. 相似文献

This article presents a preliminary examination of the potential of Technology User Groups as a professional development venue for early childhood education professionals in developing operational and functional competence in using hardware and software components of a Technology toolkit. Technology user groups are composed of varying numbers of participants having an interest in technology, and are led by one or more skilled facilitators who meet with participants across time to help them acquire and demonstrate new technology skill sets. A series of these groups were conducted with seven early education professionals serving young preschool children who were at risk or who had disabilities. The impact of these technology user groups was examined using self-reports subsequent to individual participation. Specific data were collected regarding the types of technologies that had been used, and the types of classroom instructional products that had been created and implemented in classrooms using the technologies. A discussion of the value of technology user groups is presented. 相似文献

The purpose of this study was to assess how a comprehensive precollege intervention and developmental program among low-income high school students contributed to college enrollment outcomes measured in 2006. Our focus was on the Fifth Cohort of the Washington State Achievers (WSA) Program, which provides financial, academic, and college preparation support to 500 high school students who come from the lowest 35% of Washington state income levels. One important feature of the WSA Program is that it provided funding for complete high school curriculum reform among 16 Washington high schools that have a high prevalence of low-income students. The data set contained three groups of students from these 16 high schools: Funded Achievers who were part of the WSA Program and received funding for college; Nonfunded Achievers who were part of the WSA Program and but did not receive funding for college; and Nonrecipients who were neither part of the WSA Program nor received funding for college. Results from generalized multinomial logistic models found two trends (a) early and continuous financial support for college along with being active in the WSA Program nearly guarantees enrollment in college and increases enrollment in 4-year and highly selective colleges; and (b) even in the absence of financial support for college there are still quantifiable and positive effects on college-going for just participating in the WSA Program and receiving its abundant nonfinancial resources and support. These results persist even with strong controls for selection, background, academic, financial, aspiration, and school-level variables. 相似文献

The aim of this study was to evaluate the effects of a teacher training program on teacher outcomes. The teachers’ knowledge and attitudes regarding inclusion, classroom management strategies, and their relationships with children both with and without disabilities were evaluated using self-report instruments. In addition, their classroom behaviors were evaluated by independent observers. The teacher education program included a variety of topics related to inclusion and effective strategies for inclusive classrooms. The data were collected prior to the education, after the completion of the program, and 6 months afterwards. The results indicated that the teacher program seemed to have moderate-to-large effects on all teacher outcomes, but the changes in their classroom behaviors were minimal. 相似文献

To counteract what we see as a growing research-reporting concern, we propose the following editorial-policy change regarding the content of primary research articles in educational research journals: Contributors should restrict their discussion and conclusions to their data and not offer recommendations for educational practice nor speculate about the educational policy implications of their research. We believe that this change will be beneficial for maintaining a separation between evidence and opinion concerning the legitimate warrants of empirical research. We suggest viable accompaniments and alternatives to authors offering practical recommendations and policy speculations in primary-research journal articles. Among these is to rely on all sources of evidence, including systematic research syntheses based on the aggregated contribution of multiple research studies from different sources, with recommendations for practice tailored to specific situations so that both their validity and utility will be increased. It is hoped that our proposed policy change will initiate a conversation among researchers, editors, reviewers, and educational-policy experts with respect to the scope and purpose of primary research journal articles. 相似文献
