The present study examined characteristics of students who took advantage of the opportunity to learn Algebra II from a highly skilled teacher. In particular, student information was gathered concerning: (a) the amount of mathematics students knew prior to the class, (b) their motivation for learning mathematics, (c) the number and types of interactions they had with the teacher during class, (d) degree of self-regulation, and (e) general aptitude. A model for achievement was used that suggests both opportunity and propensity are important (i.e., students must be willing and able to take advantage of opportunity). Support for the model was found. Propensity to take advantage of a highly favorable opportunity accounted for almost sixty percent of the variance in achievement. In particular, students who were self-regulated, had strong mathematics backgrounds, and had low levels of frustration benefited more from high-quality instruction.  相似文献

Agricultural development projects have been promoted in many places as a feature of poverty-reduction strategies. Such projects have often been implemented without a strong in-built education component, and hence have had little success. Agricultural projects seek to improve food security by diversifying a household’s resource base and facilitating the social and economic empowerment of women. The present study presents a survey designed to assess the relationship between education level and ability to benefit from dairy-development projects in Kenya. Results reveal higher occupation and employment levels among beneficiary than non-beneficiary households. On the other hand, beneficiaries of poverty-reduction schemes require specialized training. Apart from project-specific training, the level of general education alone cannot predict the attainment of project objectives.  相似文献

This study explores the long-term impact on participation in the Linda Ray Intervention Program (LRIP) for children (n = 54) who were developmentally delayed and prenatally exposed to cocaine. By identifying a group of programme graduates from a high crime/high poverty neighbourhood in Miami-Dade County using ArcGIS 10.2 software, a quasi-experimental design was used to compare children living in this area who participated in the centre-based modality (5 h a day; 5 days a week) to children living in this area who participated in the home-based modality (3 h per week) on their Florida Comprehensive Assessment Test (FCAT) reading and math scale scores in public school. The children who participated in the centre-based modality reported stronger outcomes in both math and reading FCAT scale scores at the p < .05 level and also out-performed their school-age peers on both math and reading FCAT scores at the p < .05 level.  相似文献

Conclusion The ever increasing demands on guidance and counseling programs has added new responsibilities to the tasks of the counselor specifically in the area of career development. Along with this increase in responsibility, the issue of accountability has been added. Career information delivery systems assist the counselor in meeting the need for accurate, relevant occupational and educational information that can be disseminated in a timely efficient manner. Therefore, CIDS should be a vital part of all comprehensive career guidance and counseling programs.Mary Elizabeth McCormac is an Occupational Information System Specialist, National Occupational Information Coordinating Committee, Washington, D.C.  相似文献

In order to determine the role of time limits on both test performance and test validity, we asked approximately 300 volunteers–prospective graduate students–to each write two essays–one in a 40-minute time period and the other in 60 minutes. Analyses revealed that, on average, test performance was significantly better when examinees were given 60 minutes instead of 40. However, there was no interaction between test-taking style (fast vs. slow) and time limits. 'That is', examinees who described themselves as slow writers/test takers did not benefit any more (or any less) from generous time limits than did their quicker counterparts. In addition, there was no detectable effect of different time limits on the meaning of essay scores, as suggested by their relationship to several nontest indicators of writing ability.  相似文献
