Two Aspects of the Teaching Quality of Soil Science in Land Remediation Engineering - Preparation Before Class and Solutions of Homework after Class

Against the backdrop of "New Agricultural Science", land remediation engineering education and talent development demand a higher level of proficiency. Helping students to promptly integrate into their professional studies, effective teaching of fundamental courses holds tremendous importance. This paper discusses the two aspects of blended teaching of Soil Science, preparation before class and solutions of homework afterclass. In the process of preparation before class, especially in the pre-study material selection and reading processing, teachers try to guide students to think more problem about soil, combined with the discipline's research hotspots, expedite students' progress towards the forefront of the discipline. In the process of answering the homework after class, on the basis of the classroom teaching content, it is useful to inspire and guide students to think about the role of soil in land remediation engineering across disciplines and sectors, so that students will have acquired a comprehensive understanding of soil with the land remediation practice organically integrated. Through guiding students in preparation before class, offline lectures, and solutions of homework after class, the objective of constructing soil science courses that are centred on competency cultivation has been fulfilled.
