Drawing on Robinson\u2019s (2001b) triadic componential framework for task design, the study explores the task demands that are inherent to tasks (task complexity) or that emerge in task\u2013learner interaction (task difficulty). Task complexity and modality were adopted as task feature variables, while goal orientation (Dweck, 1986), the L2 motivational self system (D\u00f6rnyei, 2009), and L2 anxiety were adopted as learner variables. With the mediation of task difficulty, this study examines the relative contributions of task and learner variables to task performance (complexity, accuracy, and fluency) and task experience of flow (Csikszentmihalyi, 1987). In a repeated measures design, 151 L2 learners performed four argumentative tasks that differed in task complexity and modality. They completed two questionnaires, one a pre-task survey examining dispositional motivation and the other a post-task survey probing their subjective experience with the task. Production data were analyzed to measure complexity (i.e., the clause per T-unit ratio), accuracy (i.e., the error-free clause per T-unit ratio), and fluency (i.e., pause frequency per T-unit). MANOVAs, correlation analysis, and structural equation modeling (SEM) were conducted. The results indicate that although task complexity affected the perception of task difficulty, it did not affect task performance in terms of CAF nor task experience of flow. Task modality significantly predicted task performance and task experience of flow. Significant relationships among motivational constructs were observed, but learner variables did not have a direct impact on immediate task performance or experience. These findings suggest that task variables have a stronger impact than learner variables on both language learning outcomes and affective outcomes of tasks. The study\u2019s multifaceted investigation provides insight into how various motivational and affective constructs work together and interact with various task features to produce unique task performance experiences and performance outcomes.<\/p>\n","protected":false},"excerpt":{"rendered":" Announcing<\/p>\n<\/p>\n PhD in Second Language Studies Dissertation Defense<\/p>\n<\/p>\n Chair: Richard Schmidt<\/p>\n<\/p>\n Monday, 18 May, 12:00 p.m.\u20132:00 p.m.Minyoung Cho<\/h4>\n
