Learners cannot accept responsibility for their own learning unless they have some ideas of what, why, and how they are trying to learn. This paper argues that learner autonomy may be promoted through strategy-based instruction. The intent of strategy-based instruction is to help all students become better language learners. When students begin to understand their own learning processes and can exert some control over these processes, they tend to take more responsibility for their own learning and become more autonomous. Teachers may conduct strategy-based instruction by complementing such activities as preparation, practice, evaluation and expansion.展开更多

The arm solution for the orientation of a manipulator using a self organizing neural net is studied in this paper. A new training model of the self organizing neural network is proposed by thoroughly studying Martinetz, Ritter and Schulten′s self organizing neural network based on Kohonen′s self organizing mapping algorithm using a Widrow Hoff type error correction rule and closely combining the characters of the inverse kinematic relationship for a robot arm. The computer simulation results for a PUMA 560 robot show that the proposed method has a significant improvement over other methods documented in the references in self organizing capability and precision by training process.展开更多

文摘Learner autonomy is a matter of explicit or conscious intention. Learners cannot accept responsibility for their own learning unless they have some ideas of what, why, and how they are trying to learn. This paper argues that learner autonomy may be promoted through strategy-based instruction. The intent of strategy-based instruction is to help all students become better language learners. When students begin to understand their own learning processes and can exert some control over these processes, they tend to take more responsibility for their own learning and become more autonomous.
