Fhe second part elaborates the procedure and the method of this cxpcriment.According to the achievement analysis of the final English examination (July, 1999) for Junior One in Wuzhou CLty, we applied the English Learning Strategies Inquiry Paper(Oxfoxd, 1993) to alt the samples. After being made t-Test~ to make sure that they have no obvious dissimi Ian tics in English achievement and strategies level,3 experiment classes and 3 contrast classes are chosen and dovided to 3 groups. Then they are trained half a year in 3 different ways:Group instructing Method, Self-learning---3--and-discussing Method and Permeating-in-teaching Method. The thirt part------Results and Analysis.

研究结果表明，不同的策略训练方祛、不同性别、不同成绩以及不同的训练时间对训练的效果均有不同程度的影响。1、分组指导法、自学讨论法和随堂渗透法这三种训练方式取得了不同的训练效果。2、从整体上说，男、女生英语学习策略的短期和长期训练效果都非常显著，但自学讨论法学生的短期学习策略训练效果存在性别差异。3、在不同成绩组学生的英语学习策略训练中，其短期训练效果有显著的差异，但其长期训练的效果则基本一致。4、英语学习策略训练的时问长短不同，训练效果的大小就不同。
