任务教学法在农科专业无机及分析化学课程教学中的应用

为探索教学过程中提高学生能力的途径,以"分析化学在农业科学中的应用"和"分析化学测定方法的比较"两大主题12个具体任务,在西北农林科技大学17个本科班无机及分析化学课程教学中开展了任务教学法的应用研究。研究表明,在农科无机及分析化学课程教学中应用任务教学法是可行的。任务教学法的实施改变了教学过程中的师生角色关系,改变了学生获得知识的路径,受到了学生的广泛欢迎,极大地调动学生学习的积极性、参与性和创造性。学生查阅文献能力、语言表达能力、制作PPT的能力、交际能力、组织能力、归纳总结能力、论文写作能力、创新能力和灵活运用化学测定方法解决实际问题的能力在学习过程中均得到了显著提高。

The Application of Task-based Approach in In-organic and Analytical Chemistry Course

This paper is an explorative research on the teaching of In-organic and Analytical Chemistry course by adopting task-based approach in order to cultivate college students’ competence,based on completion of 17-classes teaching practice to 510 undergraduate students of Northwest A＆F University separately.12 specific tasks from two separate chapters： ＂the application of Analytical Chemistry to agricultural Science＂,＂the comparison of the methods in measurement of Analytical Chemistry＂ was design into the task-based teaching plan.The result shows a satisfactory achievement and unexpected effectiveness of this teaching method.The new teaching method has changed the relationship of the teacher-student role.It also changed the learning method and access to acquire knowledge.Not only could this task-based approach aroused students interest and motivation in learning this course,but also cultivate students’ competence and skills,competence in expression ideas and critical thinking,in autonomous,co-operative and reflective learning and competence in doing literature review,and problem-solving,as well as improving skills in making PPT design.
