講座內(nèi)容：

Given the significance of task complexity and its role in affecting learning outcomes, in this lecture I present results of a bibliometric analysis of studies on task difficulty over a period of nearly 40 years from 1990 to 2018 using CiteSpace V, with particular reference to Peter Skehan’s contributions (Wang & Zhang, 2018). The research data, consisting of 164 research articles and their 1,706 citing references, were retrieved from the core collection of the Web of Science-SSCI database. The top 20 most often cited references were visualized and highlighted through a 406-node network of cited references. The results demonstrate that Skehan’s (2009) article was ranked as the most influential reference in studies on task difficulty or task complexity, which is clear evidence of Skehan’s far-reaching impacts on key areas in TBLT and SLA research (Wang, Wu, & Zhang, 2020). The talk will conclude with a discussion on possible future directions.
