Corder’s phrase, “ Given motivation, anyone can learn a language" brings out the importance of motivation and the way it can overcome unfavourable circumstances in other aspects of language learning. There have been overwhelming researches & literature on this area. However, the definition and study of motivation have not been without problem. This paper starts with a brief historical review on psychological approaches underlying motivational research, followed by the remarkable motivation theories. The third part is concerned with SL/FL motivation, which attempts to relate the findings on motivation with situation of China.展开更多

The main idea of this algorithm can be described as follows： disperse some worms equably in the domain; the worms exchange the information each other and creep toward the nearest high point; at last they will stop on the nearest high point. All peaks of multi-modal function can be found rapidly through studying and chasing among the worms. In contrast with the classical multi-modal optimization algorithms, SOWA is provided with a simple calculation, strong convergence, high precision, and does not need any prior knowledge. Several simulation experiments for SOWA are performed, and the complexity of SOWA is analyzed amply. The results show that SOWA is very effective in optimization of multi-modal functions.展开更多
