Persistence factors revealed: students’ reflections on completing a fully online program     

Dazhi Yang  Sally Baldwin  Chareen Snelson 《Distance Education》2017,38(1):23-36

Despite their rapid growth, online programs routinely face student attrition. How to retain students and help them successfully complete is usually a top priority for online programs. This study investigated persistence factors that contributed to students’ successful completion from one of the largest and most successful online programs in the United States of America. Results show that both personal and program attributes contributed to students’ successful completion of a fully online program. Main individual attributes include interest in or career goals related to technology, time and effort invested, and perceived utility of learning. Main program attributes include relevancy of courses to individual or professional needs, satisfaction with courses and program, and ties between coursework and job promotion. Results of this study have implications in terms of prioritizing different attributes and strategizing resources to improve completion and graduation rates for fully online programs.  相似文献   

The problem of secondary education completion: The case study of Cape Verde,a small island developing state     

《International Journal of Educational Development》2017

Like many small island developing states, Cape Verde faces a challenge with secondary school completion. The lack of global development goals for secondary education results in the lack of government policies to promote secondary education, which may in effect be partially responsible for the drop in primary school completion The purpose of this paper is to identify the student populations who leave secondary school prior to completion based on Cape Verde’s Ministry of Education data, which is disaggregated by municipality and school. In addition we link these student populations to socioeconomic factors in order to examine possible causes for their abandonment of schooling. This paper intends to draw attention to the issues facing secondary education in a small, developing island nation and highlight policies that have proven effective in similar contexts. The case study of Cabo Verde can be used to generate secondary education policy discussions in other small island developing states (SIDS), as well as other sub-Saharan African nations.  相似文献

The experience of receiving and then losing a scholarship: a tracer study of secondary school scholarship recipients in Uganda     

Cathy Watson  Charles Opolot Okurut 《Educational Research and Evaluation》2013,19(6):494-511

This study reports findings of a tracer that investigated differences in the profile and subsequent experiences of scholarship recipients in Uganda who were able to complete the lower secondary school cycle (O level) without interruption (N = 174) and those that dropped out before completing their O-level cycle (N = 51), thereby losing their scholarship. Findings indicate that the scholarship programme had important positive impacts on all participants, even if they were unable to complete their O level. Moreover, scholarships had a multiplier effect; they had positive impacts on recipients' siblings, parents, and neighbours. When scholarship recipients did drop out, the most prevalent causes were poverty, pregnancy, and poor performance. However, even the modest amounts of education these dropouts received changed the course of their lives in positive ways.  相似文献   

Accelerated matrix recovery via random projection based on inexact augmented Lagrange multiplier method     

王萍  张楚涵  蔡思佳  李林昊 《天津大学学报(英文版)》2013,19(4):293-299

In this paper, a unified matrix recovery model was proposed for diverse corrupted matrices. Resulting from the separable structure of the proposed model, the convex optimization problem can be solved efficiently by adopting an inexact augmented Lagrange multiplier (IALM) method. Additionally, a random projection accelerated technique (IALM+RP) was adopted to improve the success rate. From the preliminary numerical comparisons, it was indicated that for the standard robust principal component analysis (PCA) problem, IALM+RP was at least two to six times faster than IALM with an insignificant reduction in accuracy; and for the outlier pursuit (OP) problem, IALM+RP was at least 6.9 times faster, even up to 8.3 times faster when the size of matrix was 2 000×2 000.  相似文献

先秦文献成书时代述略     

邱渊 《安庆师范学院学报(社会科学版)》2008,27(11):53-56

现存先秦文献成书时间极为复杂,根据前人研究成果,先秦文献的思想形成或成书时代分为三个阶段：春秋以前、春秋时期、战国时期。其中成书于春秋以前的有《周易》、《尚书》、《诗》的部分内容;成书于春秋时期的有《春秋》、《左传》、《国语》等以及《尚书》、《诗》等的部分内容;成书于战国时期的有《墨子》、《孟子》、《庄子》等以及《尚书》、《周易》等的部分内容。考察并了解先秦文献的成书时代,对于正确引用和解读这些历史文献具有重要意义。  相似文献
