Many theories on college retention recognize the significance of student satisfaction as a positive factor in students’ persistence. Yet, there are few theories that address the relationship of degree program satisfaction to study behaviour and dropout. This paper explores the impact of degree program satisfaction on academic accomplishment and dropout. The impact of degree program satisfaction was studied within a multitheoretical framework. The results of the study show that student accomplishment not only depends on differences in academic ability but also on degree program satisfaction. Decreased degree program satisfaction appears to diminish both study motivation and study behaviour. The authors discuss some implications for current educational practice.  相似文献

在消费升级的大环境下,价值主张精确地传达产品的价值优势并指导资源的有效配置,能够促使企业通过优化配置资源更好地满足市场需求以获取竞争地位。采用扎根理论的研究方法透过企业资源配置现象的典型案例构建理论框架,剖析价值主张与动态能力的互动对资源配置的影响机理及其演进过程。研究表明:(1)在不同情境因素的诱发下,价值主张与动态能力快速互动调整达到相适配,进而保证价值主张的有效性并促使能力发挥到极致以完成预期目标;(2)企业依据价值主张提炼出合理的资源配置决策,并由与价值主张相匹配的动态能力作为支柱性要素对资源进行改造利用,使资源配置在价值主张与动态能力的作用下表现为“简单拼凑式-探索开发式-协奏共享式”的演进过程。本研究结论对于企业如何通过清晰的价值主张进行有效资源配置以获取竞争优势有着重要理论和实践意义。  相似文献

为推动新兴经济体的工业化进程,探讨科技全球化背景下的各国工业化发展模式和路径,急需构建一套适合新形势的工业化水平测度体系。本文基于国家创新系统国际化理论、新增长经济理论和新制度经济学理论,构建"新兴经济体工业化水平测度"的五维模型,即"发展阶段-工业竞争力-工业化效益-国际化程度-可持续发展制度"的测度模型,并运用层次分析、聚类分析、主成分分析、DEA分析等方法,测算以广义"一带一路"沿线国家为代表的新兴经济体的工业化水平。本文构建的新兴经济体工业化测度五维模型,理论上拓展了经典工业化测度理论和国家创新体系国际化理论;实践上也为中国"一带一路"战略和国际产能合作的策略提供了政策启示。  相似文献

创新激励政策的实施效果一直受到广泛关注。本文引入新制度主义的视角,讨论了企业外部环境特征对税收优惠政策实施效率的影响,并指出强制度性环境中的企业可能通过主动迎合外部要求而非提升内部效率获得回报。本文使用2009-2013年我国上市民营企业的面板数据,通过实证研究发现,税收优惠在一定程度上提升了企业的创新绩效,创新投入在其中起到完全中介作用。但是激励效果在不同企业之间存在差异。存在政治关联的企业并未将税收优惠有效地投入到创新活动中去,但同样获得了相当数额的优惠。高新技术企业所得税优惠政策在很大程度上成为了这些企业规避税收的"税盾"。本文的结果表明,税收优惠政策效率的提升应从弱化制度性环境特征入手。  相似文献

Background:?Cooperative learning may help students elaborate upon problem information through interpersonal discourse, and this may provoke a higher level of thinking. Interaction stimulates students to put forward and order their thoughts, and to understand the ideas or questions of their peer learner. However, partner gender is an important variable in cooperative learning. Previous research indicates that female students profit less than male students from mixed-gender cooperative learning in physics, especially where problem-solving is involved. Female and male students have different communication styles. For example, male students tend to give their opinions and explanations directly, while females tend to avoid presenting their opinion and are more likely to initiate cooperative problem-solving by asking questions.

Purpose:?The main aim of this study was to ascertain whether partner gender influences female students' learning to solve science problems and the role female communication style plays in the cooperative learning process.

Sample:?A total of 62 high schools students (31 female, 31 male) from three schools in the Netherlands participated in the study. Students were selected from three physics classes in grade 10, with a mean age of 15.6. Students came from various family backgrounds.

Design and methods:?An experiment was carried out to test the effect of group composition on female and male students' cooperative problem-solving in science. The students were randomly assigned to dyads and three research conditions: 15 mixed-gender pairs (MG); eight female–female pairs (FF) and eight male–male pairs (MM). Students were given training in how to solve a problem as a team, and how to complete the answer sheet. All students solved the same problems in four 50-minute sessions. In each session, students were asked to solve three new and moderately structured problems working together. Each dyad had a university student as an observer. The observer's task was to log the students' time on task and to document the interactions between the students. The observers did not interfere with the communication between the students during problem-solving.

Results:?Analyses of pre- and post-test performance revealed that female students in the MG condition did not learn to solve physics problems as well as male partners or as female students in all-female dyads. Analyses of interactive behaviours showed that female students in the MG condition devoted less time to actively seeking solutions and spent more time asking questions than their male partners.

Conclusions:?Difference in solution-seeking behaviour could explain an important part of the difference in problem-solving performance between the female and male students in this study. Female students in the all-female dyads did not differ in interactive behaviour or post-test performance from males. They had a more balanced interactive style than females in the mixed-gender dyads. Suggestions for further research are discussed. It would be interesting to examine if the findings of this study carried over to areas in which females are traditionally more comfortable, such as biology.  相似文献

Deaf and hard-of-hearing (d/hh) students are traditionally educated within self-contained programs at residential or special day schools, within self-contained or resource classrooms in public schools, or within regular education classrooms with support provided by an itinerant teacher. The co-enrollment model offers a promising alternative in which these students are educated within a regular education classroom composed of both d/hh and hearing students and team-taught by a teacher of the deaf and a regular education teacher. This article examines the development of one such program and the social and academic performance of the d/hh students within the program. Data on social interaction between d/hh and hearing classmates suggest that specific instructional strategies that promoted students' sign language development, identified d/hh students as "sign language specialists" and grouped d/hh and hearing students during academic activities resulted in increased interaction between these two groups of students. Stanford Achievement Test scores in the areas of reading vocabulary, reading comprehension, mathematical problem solving and procedures indicate that although d/hh students scored below the national normative hearing group, reading comprehension levels exceeded the national normative sample of d/hh students during both years two and three of the program. We discuss the challenges of implementing a co-enrollment program.  相似文献

大量企业同时开展独立研发和合作研发活动以期实现两者的协同效应来提高企业绩效。然而,我国企业通过整合独立研发和合作研发来提高企业绩效的目标并没有实现。本文对独立研发和合作研发的关系进行研究,并分析吸收能力在整合独立研发和合作研发提高企业绩效过程中所发挥的作用。通过对286家企业调研数据的实证检验,本文发现独立研发与合作研发存在互相抑制作用,且该作用随着吸收能力的增强而提高。本文研究深化了对独立研发和合作研发关系的认识,为企业整合独立研发和合作研发提供了指导。  相似文献
