Description¶

The review presents Skehan's (1998b) three-part measurement framework for learners' language performance, proposing "to separate learner's general goal into three specific areas: accuracy, complexity and fluency." Accuracy relates to understanding rules and performing against them; complexity deals with restructuring the interlanguage system to become more elaborate; fluency refers to the capability to mobilize current linguistic sources to communicate in real time. The measures cover both speaking and writing skills, and the review argues separate measurements for speaking and writing are needed within these areas.

Design Implications¶

Context¶

Requirements¶

• Separate measurements for speaking and writing within the three areas, because of cognitive and contextual differences between the two skills

Constraints¶

• The review notes the separation of performance measurements would result in regrouping study results in the literature review

Target Learners¶

• second language learners

Target Learning Goals¶

• accuracy
• complexity
• fluency in second language performance

Claims¶

• Strategic pre-task planning enhances learners' fluency in task-based performance [+W]
