This paper suggests chat engineering curricula should be designed on the basis that engineering is a vocation. It outlines how curricula might be developed by identifying engineering jobs and proceeding from job specification through engineering capability profiles to subjects of instruction. The need for manpower planning is stressed. Some problems related to small student numbers are outlined and some options offered for solution of such problems.  相似文献

Accurate teacher evaluations of student performance are crucial for effective teaching. This study examined whether students’ immigration and language background affect teachers’ evaluations. Multilevel analyses tested whether teachers overestimate the performance of immigrant relative to that of non-immigrant students. As part of the German PISA 2003 assessment, 305 teachers predicted the performance of seven of their students on two mathematics problems of different linguistic complexity. Results revealed an interaction effect of students’ language background and linguistic complexity of the problem on teachers’ predictions. Teachers overestimated the performance of bilingual students more than the performance of monolingual immigrant or non-immigrant students on a linguistically complex problem. Teachers need to consider both students’ language background and linguistic demands of the material used to appropriately support bilingual students.  相似文献

This article exposes the problem of using declarative rather than procedural knowledge to help K–12 students recognize irony in stories. It offers commonplace procedures drawn from students’ everyday language experience together with more abstract irony clues to help students recognize irony in stories and increase their story comprehension. Six irony-laden stories are briefly examined to underscore their basic ironic core and guide instruction of elementary, middle, and secondary students.  相似文献

This study examined data from over 300 U.S. schools on their efforts to develop high quality programs of school, family, and community partnerships. Analyses show that elementary schools, schools with greater support from parents, teachers, and the community; and schools that evaluated progress reported higher quality partnership programs over time. Higher quality programs were associated with wider implementation of parent-child interactive homework, higher levels of parent volunteering, and more parents on school decision-making committees. Results identify factors that could help schools develop quality partnership programs and suggest that these programs translate into higher levels of family involvement in students’ learning.  相似文献
