简介:identification and classification of learning strategy. The problems are reviewed concerning the definition and classification of learning strategies and then the paper tentatively introduces Cohen’s approach to defining learning strategies in terms of prototypicality of features of learning strategies.,Cohen’s attempt to describe the prototypicality of strategies is a step forward concerning defining learning strategies. It might reflect the nature of learning strategies to a large extent because the answers to the questionnaire come from strategy experts. It is true that some problems still exist. For example,all-or-nothing feature but in terms of how far along a continuum a feature could possibly go before it stopped being descriptive of a strategy. This is an approach of defining learning strategies in terms of how prototypical the feature was. These features as follows are arranged in a descending order of agreement
简介:让f(z)是为完整的模块化的组的重量k的holomorphicHeckeeigencuspform。让f(n)是f(z)的第n个规范的Fourier系数。建议那L(sym2f,s)对称的方形的L功能与f(z)被联系,并且$\lambda_{sym^2f}(n)$(n)表示第n系数L(sym2f,s)。在这份报纸,它被证明那$$\sum\limits_{n\leqslantx}{\lambda_{sym^2f}^4(n)}=xP2(\logx)+O(x^{\frac{{79}}{{81}}+\varepsilon}),$$,在P2(t)是在度2的t的一个多项式的地方。同样,它被获得那$$\sum\limits_{n\leqslantx}{\lambda_f^4(n^2)}=x\tildeP2(\logx)+O(x^{\frac{{79}}{{81}}+\varepsilon}),$$,在哪儿$\tildeP_2(t)$是在度2的t的一个多项式。
