摘 要：该文以“马铃薯试管薯诱导实验”课程为例，分析了合理“增负”对实验课程教学效果的提升作用。基于培养基中高浓度蔗糖诱导马铃薯试管薯实验的基础上，增加了观摩视频和利用最新研究成果来诱导试管薯实验的内容，并以小论文形式提交实验报告。结果表明，合理“增负”使学生掌握了多渠道生产马铃薯块茎技术，提高了综合实践技能和科研思维能力，提升了实验课程的教学效果，达到了培养应用型人才的教学目的。

Abstract： In this paper， taking the experimental course of “potato microtuber induction” as an example， analyzes the effects of “Reasonable Burden Increasing” on the teaching effects of experimental course. potato microtuber induction based on the higher sugar concentration in medium， this paper was added the contents of watching video related to tuber formation and the latest research findings were applied to the experiment，and finally submitted the experimental report in an research paper formats. The results showed that college students learned varied technology of potato tuber induction， improved the comprehensive practical skills and scientific research ability， and enhanced the teaching effect of experimental courses by “Reasonable Burden Increasing” teaching method， to achieve the teaching goal of cultivating practical talented person.

Key words： Reasonable Burden Increasing; Experimental course; Teaching effect

实验教学是培养学生实践能力、创新能力和科学素质的重要途径[1]。马铃薯种薯生产内容是农学专业开设的种子生产学课程中无性系种子生产章节中必讲授的重要内容之一，集较强的理论性、实践性和应用性于一身。马铃薯种薯生产技术涉及生物技术、栽培学、设施园艺学等多门学科，受实验课时的限制，延边大学农学院以往的马铃薯块茎诱导实验仅设置生物技术方法诱导试管薯实验，要求学生掌握马铃薯扩繁技术及诱导试管薯技术。该技术只是马铃薯种薯生产中的部分环节，满足不了知识的更新，培养创新思维人才的需求及学生就业的需求。因此，如何通过实验教学培养出理论与实践能力相结合的高素质人才，培养出生产实践能力较强的从事农业生产的人才，已成为众多农业院校教学理念和一线教师所承担的教学任务。……
