环境土壤学实验课程的启发式教学探索——以土壤酸碱度测定实验为例

Exploration of Heuristic Teaching in the Experimental Course of Environmental Pedology——A Case Study on the Soil p H Measurement Experiment

针对环境土壤学实验课程的特点及其传统"注入式"教学方法存在的弊端,该文论述启发式教学在环境土壤学实验课程应用的必要性,在此基础上以"土壤酸碱度测定实验"为例提出启发式实验教学模式的构建策略,从教学内容、教学环节及教学方法等方面探索启发式教学的具体应用方法及实施过程,并通过问卷调查分析启发式实践教学的效果及存在的问题,为今后进一步推广启发式教学在环境土壤学实验课程的应用积累经验并提供参考依据。实践表明,启发式教学的应用有利于激发学生的学习兴趣与学习主动性、促进学生对专业知识的理解和掌握,培养学生的独立探究能力。

Based on the characteristics of the experimental course of environmental pedology and the drawbacks of the traditional spoon - feeding way of teaching, the necessity of application of heuristic teaching to this experimental course was discussed. By taking the soil pH measurement experiment as a case study, the construction strategy of heuristic experimental teaching mode, which includes the application and practices of the heuristic teaching in teaching content, process and methods, was proposed. A questionnaire survey was carried out to analyze the effects and problems present in the heuristic teaching practice, which gaining experience and providing a reference for further application of the heuristic teaching in the experimental course of environmental pedology. The practice showed that the application of the heuristic teaching was beneficial to stimulate the students＇ learning interest and initiative, to improve the students＇ understanding and mastering of the professional knowledge, and to develop the students＇ ability of independent exploring.
