新农科背景下分析化学Ⅱ课程的教学创新——“四维创新”实现“四有目标”

doi:10.3866/PKU.DXHX202112072

Abstract

Abstract:

Based on the teaching concept of "student centered, output oriented, continuous improvement" and the "double-center" mode of teacher-led and student-centered under the background of new agricultural science, analytical chemistry Ⅱ has been innovated from four dimensions of teaching content, ideological and political education, teaching design and process assessment to create offline gold course. Practice has proved that curriculum teaching innovation has greatly mobilized students' subjective initiative and achieved "four goals" of cultivating students with knowledge, ability, quality and feelings. It has played a role in comprehensively promoting the construction of new agricultural science and cultivating outstanding talents of agriculture and forestry.

Key words: New agricultural science, Analytical chemistry, Teaching innovation, Ideological and political education
