分析化学中酸碱溶液pH计算的教学方法体会

Experience of Teaching Method of pH Calculation in Acid-base Solution in Analytical Chemistry

分析化学是医药院校检验、药学、制药工程和生物技术等专业的一门专业基础课,溶液的pH计算公式多、运算推理复杂,学生难于理解和记忆;方法和结果:针对不同溶液的pH计算的内容共性和个性,通过归纳总结、类比、案例分析的教学方法,举一反三,突出重点,突破难点,激发了学生的学习兴趣;结论:在教学时数缩减而不减少教学内容的情况下,有效调动学生学习主动性,取得良好的教学效果。

In laboratory medicine, pharmacy, pharmaceutical engineering and biotechnology professional,Analytical Chemistry is an important professional basic course. There are more formulas and complex mathematical operations of pH calculation in solution of Analytical Chemistry, which are difficult for students to understand and remember. According to the character and individuality of different solutions for pH calculation,the teaching methods of induction,analogy and example analysis were applied for students drawing inferences about other cases from one instance.It could give prominence to emphasis and overcome difficulties,to have stimulated students＇ interest in learning. In the case of teaching hours reduced without reducing teaching content, the students＇ learning linitiative were inspired effectively,and the better teaching effect was obtained.
