摘要： 验技能竞赛重在考查学生基础实验操作和对知识的综合运用能力，是对实验教学质量和学生的双重检验。课程组以天津市大学生生命科学竞赛的“摇蚊幼虫唾腺多线染色体的制备及观察”比赛项目作为切入点，将竞赛选手选拔和培训环节与实验教学相融合，利用学生的积极主动性，拓展第二课堂，强化基础和细节训练，培养学生深入发现和解决问题的能力。面向参赛选手发放问卷调研参赛收获，分析选手的竞赛成绩和实验课程成绩。结果表明，实验竞赛能够以赛促学，使学生主动锻炼操作技能，夯实基础，促进实验教学质量提升。

Abstract: The basic experimental skills competition focuses on assessing students’ proficiency in basic experimental projects and their comprehensive application of knowledge, serving as a dual evaluation of the quality of experimental teaching and students’ practical abilities. Using the “Preparation and observation of polytene chromosome of larvae ofChironomidae” project from the Life Science Competition for Tianjin College Students as a starting point, our course team integrated contestant selection and training with experimental teaching, leveraging student initiative to expand class time, reinforce fundamental and detailed training, and cultivate students’ ability to identify and solve problems at a deeper level. Questionnaires were distributed to participants to assess competition outcomes, which were then analyzed alongside results from the experimental courses. The findings indicated that competitive experimentation could enhance learning through active skill development, consolidation of foundational knowledge, and improvement in the quality of experimental teaching.

Key words: experimental competition, genetic experiment, teaching effectiveness, achievement analysis, polytene chromosome
