主观化标记词“好端端”     

张治 《云南师范大学学报(教育科学版)》2008,(6):57-64

状态形容词“好端端”和其他的ABB式状态词不同：由于它在词汇化过程中,词缀“端端”的“语义滞留”使它不论作何种句法成分,都要求与含有“出乎意料”语义的“对比句”同现,我们称之为“好端端”的“反预期语义标记功能”。“好端端”在共时平面上呈现出的句法位置之间存在着历时平面的语法化过程,从先到后：作谓语《作状语》作定语,各个句法位置出现的使用频率从左至右依次递增。另外,“好端端”与数量短语搭配时的所处位置前后的不同,也会对表达的主观性程度产生影响。  相似文献   

Where have all the students gone? Participation of doctoral students in authentic mathematical activity as a necessary condition for persistence toward the PH.D.     

A.H. Herzig 《Educational Studies in Mathematics》2002,50(2):177-212

The mathematics community in the U.S. has become concerned about the state of doctoral education, including concerns about high attrition rates and the small numbers of women and students from some racial and ethnic groups. This paper proposes a model of doctoral student persistence and attrition, in which student participation in the life of the department and discipline lead to increased student integration, which is crucial for students' success. Ten faculty members and eighteen graduate students were interviewed about their interests,conceptions, and experiences within mathematics, in a case study of one mathematics department. In this department, students experienced four types of obstacles to their participation: obstacles stemming from the program structure, obstacles to participation in class, obstacles to participating with faculty outside of class, and obstacles stemming from faculty beliefs about teaching and learning. Implications for the retention of mathematics doctoral students are discussed. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

Interventions in education to prevent STEM pipeline leakage     

Anniek van den Hurk  Martina Meelissen  Annemarie van Langen 《International Journal of Science Education》2019,41(2):150-164

The so-called leaking STEM pipeline (dropout in STEM education) has been the subject of many studies. The large interest of scholars in plausible causes of this leakage has resulted in a number of meta-reviews describing factors at system, school and student level related to interest and persistence in STEM education. The STEM pipeline discussion has also resulted in a large number of programmes aimed at enhancing STEM interest and persistence in STEM education. Although these programmes have been widely evaluated, there seems to be no consensus about which interventions are successful in raising interest in STEM or persistence in STEM education. This study reports the results of a systematic review of empirical studies in which the effectiveness of STEM-related interventions are assessed. Initially, 538 studies were found. The quality analyses showed that only a few of these evaluation studies are designed in such a way that it is likely that the found effects are caused by the intervention. Although some potentially effective interventions were found, this review shows that there is still a need for research into the effectiveness of those programmes, especially with regard to programmes preventing talented and initially motivated STEM students to drop out of STEM education.  相似文献   

Flight turbulence: the stormy professional trajectory of trainee early years’ teachers in England     

Ian Barron 《International Journal of Early Years Education》2016,24(3):325-341

This paper documents trainees’ ‘flight turbulence’ as they negotiate the complexities that lie between ‘the self’ and the securing of Early Years Teaching Status in England. Early Years Teachers, besides teaching, are expected to lead improvements to the quality of provision. However, drawing on interview data, an impasse is discerned where ideas meet instrumental policy in practice. Trainees are often unable to reshape the meeting of theory, policy and practice, and struggle in finding teaching approaches which they are comfortable with ethically. Drawing on Holland et al.’s concept of ‘figured worlds’, it is suggested that the development of theory-informed practice should not be seen as a solitary task for the student but as a dialogic though difficult conversation involving the student, university staff and placement practitioners. Dialogism is seen as requiring persistence but as offering opportunities for beginning early years’ teachers, with support from teacher educators and experienced practitioners, to negotiate the challenging spaces between policy, theory and beliefs as they seek to construct, deconstruct and reconstruct ethical professional identities for themselves.  相似文献   

Using texting to nudge urban public school students to and through college     

Ryan Yeung  Phuong Nguyen-Hoang 《Journal of Research on Technology in Education》2020,52(1):113-127

Abstract

This study investigates how a network of New York City public schools use texting to increase enrollment and persistence in college. Text messages include tips and reminders to fill out the Free Application for Federal Student Aid as well as college tips. Our multiple regression results suggest that although when the texting began did not appear to matter, the texting program increased enrollment and persistence in college. In addition, response rates were positively associated with enrollment and persistence. Finally, we find that the content of the messages themselves as well as individual characteristics affected response rates.  相似文献
