目的 对该培训基地师资2021—2023年教学能力进行评价，了解和分析“1+3+n”的院级督导推行前的2021年、“1+3+n”的院级督导推行后的 2022年、2023年师资的教学能力变化。方法 采用问卷调查法收集评价数据，采用SPSS.27.0对教学评价资料进行统计分析，采用净推荐值计算教学口碑，对多年度结果进行纵向比较分析。结果 2021—2023年教学评价次数共5 483次；2021—2023年对师资教学设计能力评价由实施前的8.8提高到9.6、教学实施能力由实施前的9.0提高到9.5、教学热情由实施前的9.0提高到10.0、时间投入由实施前的9.3提高到10.0，不同年份组间比较的差异均有统计学意义（P＜0.001）；课程净推荐值由实施前的60.5%提高到81.3%，师资课程推荐者占比由实施前的65.5%提高到83.2%，贬损者占比由实施前的5.0%降低到1.9%，差异有统计学意义（χ 2 =175.4，P＜0.001）。结论 “1+3+n”院级督导模式的相关举措，对师资教学能力的提高具有促进作用，且该促进作用持续存在，师资教学能力逐年递增。
Objective To evaluate the teaching ability change of teachers from 2021 to 2023，including of teachers’ teaching ability in 2021 before the implementation of "1+3+n" college-level supervision，and in 2022 and 2023 after the implementation of "1+3+n" college-level supervision．Methods Questionnaire survey was used to collect evaluation data，SPSS.27.0 was used to make statistical analysis of teaching evaluation data，and NPS（Net Promoter Score）was used to evaluate teaching quality．Results From 2021 to 2023，there were 5483 teaching evaluations．From 2021 to 2023，teaching design ability evaluation score increased from 8.8 before the implementation to 9.6，teaching implementation ability evaluation score increased from 9.0 before the implementation to 9.5，teaching enthusiasm evaluation score increased from 9.0 before the implementation to 10.0，time investment evaluation score increased from 9.3 before the implementation to 10.0，and the differences between different years were statistically significant（P＜0.001）．The courses quality increased from 60.5% before the implementation to 81.3%，and the proportion of teachers' course recommenders has increased from 65.5% before the implementation to 83.2%，while the proportion of detractors has decreased from 5.0% before the implementation to 1.9%，with statistical significance（χ 2 =175.4，P＜0.001）．Conclusions The measures of "1+3+n" college-level supervision mode promote the improvement of teachers’ teaching ability，the promotion effect persists，and the teaching ability increases year by year．
