语言是影响少数民族学生学业成就的关键因素之一，在四川凉山彝族地区，语言因素对彝族学生学习成绩的影响在小学阶段表现非常明显，语言因素对中学阶段彝族学生学业的影响也很大，甚至在大学及以后都有不同程度的影响。解决凉山彝族学生语言这一影响因素的关键在于实施良好的双语教育。凉山彝族地区民族学校教学活动的重要形式是实行彝汉双语教学，在某种意义上说，凉山彝族地区双语教学的质量高低决定了凉山彝族教育发展的整体水平，从而影响凉山彝族地区经济的发展和文化的繁荣。从新中国成立到现在，凉山彝族地区彝汉双语教学的到了很大的发展，取得了很好的成绩，但也有些问题。本论文中，笔者试图以双语教学理论、第二语言学习理论和少数民族成绩归因理论作为理论基础，以凉山州盐源县民族中学为个案，运用观察、访谈、问卷调查方法对其进行实地调查，了解彝汉双语教学的具体实施情况、凉山彝族各不同群体对彝汉双语教学的认识和态度，综合分析导致彝汉双语教学存在的问题和存在问题的原因，力图对彝汉双语教学的科学发展提供政策性建议。本论文主要分为以下几章：第一部分：导论。论述了论文选题背景和意义，介绍了国内外双语教学的研究状况及国内少数民族双语教学和凉山彝族双语教学的有关资料，对研究方案进行简单概述。第一章首先主要阐述国外与双语教学有关的理论基础和我国的民族双语教学模式，然后介绍凉山彝族彝语使用的基本情况和教育状况。简单概述了彝汉双语教学的历史。第二章是实地调查部分，选取凉山州盐源县民族中学为个案，通过观察、访谈和问卷调查法，展示该学校双语教学的实施情况，学生、教师和家长对彝汉双语教学的认识和态度。第三章主要分析了目前凉山彝族地区中学校在实施彝汉双语教学中取得的成绩和存在的问题，并结合访谈辑要或问卷调查的统计结果，对其存在问题的原因进行探讨。第四章基于以上对彝汉双语教学影响因素的分析，从提高凉山彝族人民对双语教学的认识，转变其态度，改善教育环境和条件等方面对凉山彝族双语教学提出政策性建议。
