基于领导者-追随者混合结构模型的创新扩散实证研究

本文借用经济学中领导者、追随者的概念，建立领导者-追随者混合结构模型来研究创新扩散的行为模式。领导者和追随者区别在于他们创新采纳行为的驱动力，而不是他们采纳时间的早晚。研究结果表明：创新扩散速度不是单调的，而是经历了一个先升后降的过程，最后收敛于领导者的采用速度；扩散过程中存在“高科技裂谷”现象；领导者在创新扩散中一直起着举足轻重的作用。     

A Review of Research on Technology-Assisted Teaching and Learning of Chinese as a Second or Foreign Language from 2008 to 2018

More and more studies are examining the use of technology in the teaching of Mandarin Chinese as a second or foreign language (L2 Chinese). The current study involved a systematic review of the literature in the field published outside China from 2008 to 2018. A total of 33 studies met the inclusion criteria. The current review study aimed: (1) to examine the research topics and technologies used in the literature; (2) to identify the benefits of, and challenges involved in, the use of technologies in L2 Chinese teaching and learning; and (3) to suggest implications for practitioners and directions for further research. The review study provides educators and researchers with an overview of recent developments in this field, which could be helpful in informing teaching practice and further research.

The relationship between motor skills difficulties and self-esteem in children and adolescents: a systematic literature review

Research findings indicate that there appears to be a relationship between poor motor skills and self-esteem, however this relationship is ambiguous. This review examines the effects of poor motor skills on global and/or domain specific self-esteem. Four databases, Google Scholar and the Manchester Online library were searched for articles focusing on motor skills and self-esteem in children and adolescents. A date range of between January 2000 and July 2015 was specified to ensure sufficient overlap with the most recent meta-analysis. From the database searches, 26 potentially relevant studies were identified and from these 26, eight studies met the inclusion criteria. A synthesis of the studies reveals that there appears to be a relationship between motor skills and self-esteem, however this relationship is complex and likely to vary depending on age, gender and co-morbidity. Implications for educational psychology practice are discussed.
