摘　　要：为实现小学生减负和作业实效提高同步的目标,在小学英语作业现状和社会各影响因素的基础上,重点分析家长与学生学习的相关性,依据共生理论构建"教师—学生—家长"共生模型。利用BP神经网络软件进行学习训练,确定出合理的小学英语作业实效投入分配比例,提高作业实效。考虑到教学环境的多样性,以及学生家长的投入与产出实效难以用学生成绩与工作时间长短来衡量其价值,可以通过偏离对称共生状态系数来调整共生单元的投入比例,以保证共生模型处于最佳稳定状态,使学生英语作业实效能够获得理论上的良好水平。In order to reduce study load along with homework efficiency improvement, considering primary school English homework status and social influence factors, the ＂teacher-student-parents＂ symbiotic model was constructed according to the symbiosis theory,which analyzes the relation between parents and students＇ learning. With BP neural network, the reasonable distribution ratio of efficiency input was made to improve the efficiency of English homework. Considering the diversity of teaching environment and the difficulty of evaluation on efficiency with students＇ marks and learning time, the symbiotic model can adjust the input of the symbiosis units dynamically with the distribution of coefficient ratio, which could keep the model in the most stable state. The model could evaluate and improve the homework efficiency effectively.
