Engineering education has a long and satisfactory developmental history in Greece. On the other hand, industrial development, which is the product of systematic government policy of the post-war period, presents mixed results. It is a fact that engineering education, at least to the extent represented by formal, structured university curricula, has not been associated in any direct way with industry, for a variety of reasons—structural, economic, and administrative, originating both in industry and university. The scene appears to be changing in recent years, under pressure from many sides. It remains to be seen whether the long overdue convergence of the two systems will materialise in the near future.  相似文献

The authors evaluated the effectiveness of the Skilled Counselor Training Model (SCTM; M. H. Smaby, C. D. Maddux, E. Torres‐Rivera, & R. Zimmick, 1999) in teaching counseling skills and in fostering counselor cognitive complexity. Counselor trainees who completed the SCTM had better counseling skills and higher levels of cognitive complexity than did counselor trainees who did not receive the training. Before training, both experimental and control group participants overestimated their skills performance. The control group persisted in this overestimation after training, whereas students who completed the SCTM had a much more accurate self‐assessment. Results suggest that skills‐based training may improve counseling skills and cognitive complexity in counselor trainees.  相似文献

This study examined the effects of social influences in the lives of an ethnically diverse sample of fifth through eighth grade students with and without learning disabilities (LD) using survey data and academic achievement scores collected in 19 Chicago public schools from 1993–1997. Similarities and differences in student perceptions of school, family, and peer group contexts were examined. In addition, longitudinal data were analyzed using hierarchical linear modeling (HLM) to identify contextual influences on changes in student reading achievement over time. Comparisons of student responses confirm and extend existing findings in the literature concerning the perceptions of students with LD of their social environments. In particular, having a learning disability was associated with consistent, mostly negative, effects on social relations across the contexts of students’ lives, regardless of gender, race, grade, and socioeconomic status. In addition, student perceptions of their friendship groups were found to have small, but significant, effects on their growth in reading achievement over the course of middle school. While students with and without LD had somewhat different views of their social contexts, the processes working within these environments appeared to affect their reading achievement in similar ways. The results suggest that careful attention should be paid to the social contexts of students’ lives when planning academic interventions.  相似文献
