You can lead a horse to water but you cannot make him learn: Smartphone use in higher education          下载免费PDF全文

Smartphone technology is penetrating world markets and becoming ubiquitous in most college settings. This study takes a naturalistic approach to explore the use of these devices to support student learning. Students that had never used a smartphone were recruited to participate and reported on their expectations of the value of smartphones to achieve their educational goals. Instrumented iPhones that logged device usage were then distributed to these students to use freely over the course of 1 year. After the study, students again reported on the actual value of their smartphones to support their educational goals. We found that students' reports changed substantially before and after the study; specifically, the utility of the smartphone to help with education was perceived as favorable prior to use, and then, by the end of the study, they viewed their phones as detrimental to their educational goals. Although students used their mobile device for informal learning and access to school resources according to the logged data, they perceived their iPhones as a distraction and a competitor to requisite learning for classroom performance.  相似文献   

状态共情、情境安全程度对助人行为的影响——人际信任的调节作用     

夏勉  王远伟 《华中师范大学学报(人文社会科学版)》2015,54(4)

采用情景实验法对234名大学生进行了调查,考察了状态共情和情境安全程度对助人行为的影响,同时探讨了人际信任的调节作用.研究结果发现:(1)状态共情与情境安全程度对助人行为均有正向预测作用.(2)人际信任负向调节情境安全程度对助人意愿的影响,正向调节状态共情对助人时间的影响.即在低人际信任组,情境安全程度与助人行为的相关更高;在高人际信任组,状态共情与助人行为的相关更高.  相似文献   

Iraqi,Syrian, and Palestinian Refugee Adolescents' Beliefs About Parental Authority Legitimacy and Its Correlates          下载免费PDF全文

Judith G. Smetana  Ikhlas Ahmad  Laura Wray‐Lake 《Child development》2015,86(6):2017-2033

This study examined intra‐ and interindividual variations in parental legitimacy beliefs in a sample of 883 Arab refugee adolescents (M_age = 15.01 years, SD = 1.60), 277 Iraqis, 275 Syrians, and 331 Palestinians in Amman, Jordan. Confirmatory factor analyses showed distinct latent factors for moral–conventional, prudential, and personal legitimacy items. Older adolescents rated legitimacy lower for personal issues, but higher for prudential issues. Beliefs were associated with socioeconomic status (fathers' education, family size), particularly for personal issues, but were more pervasively associated with displacement‐related experiences. Greater war trauma was associated with less prudential legitimacy for all youth and more authority legitimacy over moral–conventional issues for Syrian youth. Greater hopefulness was associated with more authority legitimacy over all but personal issues.  相似文献

近年来，我国出口商品频繁被外国反倾销，而企业在反倾销应诉中不够积极，导致出现不利的后果。为了逐步改变中国出口产品长期以来大量遭遇反倾销而无法进行有效应诉的尴尬和被动局面，为中国产品进入国际市场创造公平的国际贸易环境，确保中国出口贸易持续发展。在文中提出了一些对策。  相似文献   

Use of digital game based learning and gamification in secondary school science: The effect on student engagement,learning and gender difference     

Amna Khan  Farzana Hayat Ahmad  Muhammad Muddassir Malik 《Education and Information Technologies》2017,22(6):2767-2804

This study aimed to identify the impact of a game based learning (GBL) application using computer technologies on student engagement in secondary school science classrooms. The literature reveals that conventional Science teaching techniques (teacher-centered lecture and teaching), which foster rote learning among students, are one of the major concerns in Pakistan Education system. This leads to student disengagement in science lessons eventually resulting in student absenteeism and dropouts from the schools. This study consisted of five stages: (1) examining the impact of Digital Game-Based Learning (DGBL) and gamification on engagement, learning and gender difference, and literature related to using DGBL models for instructional design; (2) planning learning activities and developing a GBL application based on a specific content in Science; (3) conducting an intervention with a sample of 72 participants of 8th grade (aged 12–15) in a low cost private school of Pakistan following quasi-experimental research framework; (4) observing behaviour and emotions of the participants during science lessons; (5) conducting pre and post tests to assess the learning outcomes of participants followed by focus groups discussion. Analysis from Friedman test, Mann-Whitney U test, and Wilcoxon Signed Rank test show that the GBL application has a positive influence on student engagement. However, GBL application was not equally effective for all students since girls outperformed boys in terms of engagement and learning outcomes. This study gives insights into the development of better educational games to promote student learning.  相似文献

黑龙江省对外贸易与经济增长的协整关系和因果关系分析     

张冕  李玉凤  高长元 《科技与管理》2007,9(6):7-10

依据黑龙江省1980～2004年的统计数据,运用单位根检验、协整检验、格兰杰检验等方法对数据进行分析得出,黑龙江省的经济增长与进、出口贸易之间存在着长期稳定的均衡关系,但是经济增长与进、出口贸易的因果关系不是十分显著,仅有进口总额增长和经济增长之间存在较为显著的单向因果关系。  相似文献   

Synthesis of singly-terminated ladder networks by multivariable array using homogeneous polynomials     

B. Raman  V. Ramachandran  M.O. Ahmad  M.N.S. Swamy 《Journal of The Franklin Institute》1982,313(6):353-372

This paper discusses a multivariable array whose elements are multivariable homogeneous polynomials which may have missing terms in any of the variables. This array permits one to obtain conditions for the realizability of a driving-point function or a transfer function as a resistively terminated low-pass ladder network. By reac- tance transformations, other forms of ladder structures can be obtained. The case of cascade-separable ladder networks is discussed in detail.  相似文献
