人的主体性发展水平是影响社会文明进步的重要因素，是人的发展水平的重要标志。二十一世纪科学技术的突飞猛进和知识经济的快速崛起，对人的主动性、创造性提出了新的要求，教育作为培养人才的主要途径，要充分关注学生的主体性问题。班级文化具有塑造人的功能，对学生一生产生重要影响。作为社会主流文化的次级文化，班级文化为学生提供来自成人世界的价值规范和行为指导，良好的班级文化能够培养学生高尚的道德品质，促成学生优良的行为规范，丰富学生智能发展的途径，发展学生的审美情怀，从而实现学生自由、全面的发展，但是班级文化教育作用的真正实现依赖于学生主体地位的确立和学生主体性的实现。中学生作为班级文化建设的主体，具有双重角色，他们既是班级文化的创造者，又是班级文化的享用者，主体地位的真正实现，是其作为主体的主动性、目的性、选择性和创造性在双重角色中都能得到体现和实现。但是中学生作为成长中的个体，其身心特点对创造主体和享用主体的实现表现出一定的特殊性，即其处于由幼稚的儿童期逐渐向成熟的成人期过渡的阶段，其性格、思维方式、情绪情感、心理状态都表现出一定的特殊性。中学生自我意识逐渐显现，独立性逐步增强，既有参与到班级文化建设中的意愿，又有依赖他人、推卸责任的表现，使主体性的表现呈现出一定的缺失性。但也正是中学生处于人生发展的关键时期这样一个特点，赋予了其成为班级文化建设主体的内在驱动力，加之新课程改革的大力实施，为学生实现其在班级文化建设中的主体性提供了有利的客观环境。所以，只要教师能够正确发挥主导作用，改变视班级文化为班级管理手段的观念，关注中学生的发展需要，结合中学生的身心特点，挖掘中学生的内在潜力，赋予中学生一定的班级文化的建设权、组织权、参与权和评价权，那么就能真正实现学生在班级文化建设中的主体性，真正实现班级文化的素质教育功能。
