Objective To design the second classroom of geriatric nursing in higher vocational colleges and explore the implementation effect.

A total of 76 students who selected the course were taught. Before and after the teaching，the Kogan’s Attitudes towards Old People Scale，the Geriatric Nursing Career Motivation Questionnaire，the students’ comprehensive scores and course satisfaction were used to compare. Through the text analysis of the students’ reflection report on the course activities，the teaching effectiveness was clarified. Results The course score of 76 students was （90.12±1.67） points. At the end of the course，the total score of the students’ attitude towards the elderly was （143.38±15.74） points. The value and expectation dimensions of the motivation of choosing a job in geriatric nursing were（59.30 ± 3.01） and（25.84±2.85） points，respectively. The scores were significantly higher than those before teaching（129.49±15.91，51.19±4.43，19.92±3.24）（P<0.05）. The analysis of students’ reflection report classified five themes namely，consolidated the knowledge and skills learned in the first classroom，enhanced the interest in learning，enhanced the psychological quality and interpersonal communication ability，changed the stereotype effect on the elderly，and deepened the post cognition and professional identity. Conclusion The construction of the second classroom of geriatric nursing in higher vocational colleges is scientific and reasonable，which consolidates the learning of the first classroom，and students are highly satisfied with the course. It is helpful in improving students’ attitude towards the elderly and enhanced students’ willingness to engage in geriatric nursing.
