分析高校理科教学中双语教学的现状

摘要随着对既掌握专业知识又英语水平较高的学生的需求增加，国家教育部颁布了支持高校推进展开双语教学的通知。双语教学中的两种语言分别为学生的母语和正在学习的一门外语，它是借由两种语言来促进提高学生学习的一种教学手段。许多高校通过设立双语课程来迈出双语教学的第一步。然而，双语教学并非是一项简单地工程。它包括教学内容，教学模式，课程设置，教师培养，教学材料，教学安排和教学评价等几个方面。

本篇论文将解释双语教学的基础理论，包括内容，类型和模式；从语言学和心理学的观点来探索双语教学的本质。接着通过在杭州师范大学化学与化工学院和临床医学专业的调查研究，来发现双语教学归纳当前双语教学在我国高校的理科教学中的实际应用，并总结出差异与问题所在。最后将讨论可行的措施来帮助解决这些问题。
