Tasks, Abilities, and Aptitudes

How do teachers design and deliver a sequence of tasks that sustains learner effort to use the L2 (second language), from beginning to end, and which simultaneously leads to L2 learning and development?  In responding to this pedagogic question, this volume presents theoretical connections among three significant areas of language learning-tasks, abilities, and aptitude. For research into aptitudes, abilities and task demands to be cumulative, and its potential for pedagogic application during instructional systems design to be made clear, the author proposes a working taxonomy of task characteristics that can be linked to measurable differences in the abilities learners bring to task performance.
