Gender Differences in College Students' Career Maturity and Perceived Barriers in Career Development
Darrell Anthony Luzzo 《Journal of counseling and development : JCD》1995,73(3):319-322
Gender differences in 401 college students' career maturity were investigated. Quantitative measures included career-mature attitudes, career decision-making skills, and vocational congruence. Analyses revealed that female students scored significantly higher than did male students on each of the career maturity measures (p < .005). Nearly one third of the students (n = 128) were also interviewed. Qualitative analyses of the interviews revealed that the perception of barriers may serve as a motivating force in many students' career development. Findings suggest that current theories of career development may be lacking in their application to many of today's college students. Ideas for future research on the perception of barriers to career attainment are discussed. 相似文献

A relatively inexpensive and reliable computer-aided method for assessing Morris water maze performance is described. The procedure uses SigmaScan digitizing software (Jandel Scientific, San Rafael, CA) to collect distance swum data, while escape latencies are measured with a hand-held stopwatch. Swim paths are videotaped for subsequent viewing and saved on disk as data sets ofx,y coordinates. At a later time,x,y data files are printed and analyzed to obtain additional performance measures (e.g., distance swum in previous reinforced quadrant, heading angle, etc.). Intra- and interrater reliabilities associated with this method are presented. Correlation coefficients in ther = .85?.90 and above range are reported for both reliability types. Given its approximate cost of $1,500 (excluding the price of an IBM-compatible computer), the present procedure potentially can aid in performing instructional and research activities at small colleges which typically lack extensive equipment budgets. 相似文献

Socratic method and intuition are two ways of knowing commonly thought as opposed. The author shows how both ways of knowing can be linked in an education that has philosophy as its armature. 相似文献

This paper describes a pilot follow-up study of a behavioral program for 20 young people with learning disabilities and challenging behavior. Eighteen participants made good overall improvement during the treatment period, and this was partially maintained at follow-up. Eight had continued to improve, eight had deteriorated slightly and four had deteriorated markedly. Adaptive skills were generally maintained. The reemergence of challenging behaviors explained the difference between the Good and Poor Outcome groups. Those participants in the Good Outcome group were younger on admission, scored lower on adaptive skills and higher on challenging behaviors. In addition they had remained on the treatment programme for 12–18 months and had been discharged from the Unit for longer. The overall level of independent living had increased from preadmission and the majority of participants were living in less restrictive placements. These results confirm and extend the findings of previous research. The paper concludes by highlighting the need for more detailed longitudinal follow-up studies in this area. 相似文献

Although the Rescorla-Wagner model is widely taught in learning courses, most textbooks present a simplified version that does not contain all of its parameters. On the basis of Rescorla and Wagner 1972) and the Turbo PASCAL program by Lachnit, Schneider, Lipp, and Kimme! (1988), we created a simulation using STELLA-II, an icon-based program by High Performance Systems, Inc. We argue that this simulation facilitates teaching the complete Rescorla-Wagner model. Using trans-switching (Kimmel & Ray, 1978; Lachnit, 1986; Murrin & Kimmel, 1986) as an example, we demonstrate the effectiveness of the STELLA-II version of the Rescorla-Wagner model as a heuristic tool. 相似文献

This study compared prototype and rote instruction of English names for Chinese visual characters. In the prototype condition, participants were taught the meaning of the prototype that served as the distinctive feature of multicomponent characters. In the rote condition, participants traced the character and wrote its translation. Participants learned more rapidly and maintained more words in the prototype condition. 相似文献

The Impact of Procedural Justice on Opinions of Public Policy: Solid Waste Management as an Example1
This study assessed the applicability of Tyler and Lind's (1992) relational model of authority to the context of local government policies on solid waste management. Tests of the hypothesized relations proposed by Tyler and Lind, accomplished through structural equation modeling, revealed that our data supported the relations between the various constructs of the model. Perceptions of both process control and relational process were found to be positively related to procedural fairness judgments, while procedural fairness judgments were weakly related to evaluations of government entities. Contrary to our expectations, a similar structural equation model test of an extension of the Tyler and Lind model showed that the model constructs were unrelated to respondents' opinions of public policies. The results also indicated that respondents living in communities with different infrastructures and political climates differed slightly in their perceptions of procedural justice and related constructs, but did not differ in their endorsement of the various solid waste management policies. 相似文献
