PBL教学模式在土壤肥料学教学中的应用分析

Abstract

本文基于问题导向性(Problem-Based Learning, PBL)教学模式在土壤肥料学中的应用展开研究。以2015~2016学年第二学期农学和种科专业对口班级共113人作为研究对象进行试验。农学专业对口班级使用PBL教学方法，种科专业对口班级使用传统教学方法。在学期中、学期末对学生进行调查问卷和考试的方式测评，比较PBL教学模式与传统教学模式的效果，并结合土壤肥料学教学特点，分析了PBL教学模式在土壤肥料学教学中的应用效果。结果表明，PBL教学模式在土壤肥料学教学中的应用，很受学生欢迎，满意率很高；学生对知识点理解更透彻，并能学以致用；老师备课更加充分，提前准备多样化教学案例和素材，提升了土壤肥料学教学质量；师生互动频繁，学生学习主动性明显增加，同时也有利于增进师生感情。 This paper was carried out to analyze the application of Problem-Based Learning (PBL) teaching model in soil and fertilizer science. A total of 113 students in the second semester of the 2015 - 2016 academic year were tested. The PBL teaching method was used for the professional coun-terparts’ class of Agronomy, and the traditional teaching method was used in the professional counterpart’s class of Seed Science and Engineering. In the midterm and at the end of the semester, both of the two class students were assessed by the questionnaire and the way of examination, so that we could evaluate PBL and traditional teaching mode. And combined with soil and fertilizer science teaching characteristics, we analyzed the application effect of the PBL teaching mode in the soil and fertilizer science. The main results showed that the PBL teaching mode in the teaching of soil and fertilizer science was very popular with the students, the satisfaction rate was high; the students understood the knowledge more thoroughly and learned to use it; the teacher prepared the lessons more fully, collecting diversification of teaching cases and materials in advance, thus enhanced the teaching quality of soil and fertilizer science; frequent interaction between teachers and students, students learning initiative increased significantly, but also conducive to the emotion between teachers and students.
