This study tested two types of career training (field exposure and didactic classroom) to determine which is more effective in bringing about the development of career maturity. Forty-six first-year Upward Bound students were assigned to either a field exposure or a didactic group by the use of a stratified random assignment technique. A pretest/post-test design was utilized with the Career Maturity Inventory as the data-collecting instrument. The data were analyzed by analysis of covariance. The results of the study indicate that field exposure career training is an effective method to increase career maturity. 相似文献

This study tested the sensitivity of J. L. Holland's (Making vocational choices: A theory of careers, Englewood Cliffs, N.J.: Prentice-Hall, 1973) congruence method for predicting differential outcomes in the case of subtle person-environment congruence differences. This question is relevant to engineering programs, where students with adjacent Holland orientations of Investigative (I) and Realistic (R) aspire to complete theoretically oriented engineering majors, such as electrical and mechanical engineering. It was hypothesized that high congruence (e.g., I-type student in I-type engineering major) compared to moderately high congruence (e.g., R-type in I-type major) would result in more positive educational outcomes. A preliminary analysis verified that subgroups of I- and R-type students possessed similar scores on measures of general and math aptitude. Results on both outcome measures favored the high student-curriculum congruence hypothesis. I- compared to R-type subjects demonstrated greater persistence in their initial engineering major over a 2-year period and attained higher grades. Persistence findings replicated across two separate classes of entering students, but academic performance differences were not as consistent. 相似文献

Multidimensional scaling procedures were applied to checklist measures of stages from O. V. Tiedeman and R. P. O'Hara Career development: Choice and adjustment, New York: College Entrance Examination Board, 1963, vocational decision-making paradigm. Responses from two high-school samples were analyzed in order to test the hypotheses that stages are ordered as theory predicted and that stages represent dominant psychological states. The stage order hypothesis was essentially supported by findings from scaling solutions applied to two 11th-grade and one ninth-grade sample. The important exception was that the last two stages were reversed. Apparently grade level was not the dimension on which stages unfolded. The stage dominance hypothesis was not supported by the evidence. Student responses were not predominantly associated with a single stage but rather were distributed over several stages. Both results were interpreted in terms of the theory and the instruments. A second conclusion was that metric unfolding is a useful method for analyzing cross-sectional data bearing on construct validity for ordered stage constructs. 相似文献

By extending a technique for testing the difference between two dependent correlations developed by Wolfe, a strategy is proposed in a more general matrix context for evaluating a variety of data analysis schemes that are supposed to clarify the structure underlying a set of proximity measures. In the applications considered, a data analysis scheme is assumed to reconstruct in matrix form the given data set (represented as a proximity matrix) based on some specific model or procedure. Thus, an evaluation of the adequacy of reconstruction can be developed by comparing matrices, one containing the original proximities and the second containing the reconstructed values. Possible applications in multidimensional scaling, clustering, and related contexts are emphasized using four broad categories: (a) Given two different reconstructions based on a single data set, does either represent the data significantly better than the other? (b) Given two reconstructions based on a single data set using two different procedures (or possibly, two distinct data sets and a common method), is either reconstruction significantly closer to a particular theoretical structure that is assumed to underlie the data (where the latter is also represented in matrix form)? (c) Given two theoretical structures and one reconstruction based on a single data set, does either represent the reconstruction better than the other? (d) Given a single reconstruction based on one data set, is the information present in the data accounted for satisfactorily by the reconstruction? In all cases, these tasks can be approached by a nonparametric procedure that assesses the similarity in pattern between two appropriately defined matrices. The latter are obtained from the original data, the reconstructions, and/or the theoretical structures. Finally, two numerical examples are given to illustrate the more general discussion. 相似文献

A detailed exploration of the role of diagnostic practices is presented, with special attention given to such practices in school psychology. Basic principles related to diagnostic typology and concepts of reliability and validity are reviewed in the context of recent diagnostic decision-making research. Finally, the intrusion and eventual reduction of particular errors of consistency and inconsistency and psychodiagnosis are examined with a view toward improvements in future training and practice. 相似文献

Forty educably mentally retarded (EMR) students were randomly selected and assigned to one of two treatment groups. Students in the experimental group were verbally praised after their responses to the WISC-R questions, while the students in the control group received nonevaluative procedural comments. The scaled scores for five of eleven subtests, in addition to the Verbal, Performance and Full Scale indices, were significantly greater under the experimental procedure. The treatment's efficacy and considerations for future research were noted and discussed. 相似文献
