幼兒教師工作玩興與工作投入存在重要關聯。為了探討工作玩興對工作投入的影響機制，本研究採用幼兒教師工作玩興量表、教師自我效能感量表、幼兒教師工作投入量表，對835名幼兒教師進行調查。研究發現，幼兒教師工作玩興、工作投入與自我效能感水準中等偏上；幼兒教師工作玩興能顯著預測其工作投入水準，且自我效能感在工作玩興與工作投入間起部分中介作用。因此，提高幼兒園教師專業素養及職業准入門檻，加強組織玩興建設，改革職前培養制度，改善工資待遇，對於促進幼兒園教師工作投入具有重要意義。

There was positive correlation between kindergarten teachers’ job playfulness and their job involvement. In order to explore how job playfulness affect job involvement, 835 kindergarten teachers were investigated using Kindergarten Teachers’ Job Playfulness Scale, Teacher Self-efficacy Scale, and Kindergarten Teachers’ Job Involvement Scale. It showed that kindergarten teachers’ job playfulness, job involvement, and self-efficacy were above their medium levels; Kindergarten teachers’ job playfulness significantly predicted their job involvement; And self-efficacy played a partial mediating role between job playfulness and job involvement. So it is important for kindergarten teachers’ job involvement to improve their professional qualifications, occupational entry thresholds, and organizational playfulness climate; And also it was necessary to reform the preservice training system, and increase teachers’ salaries with balancing rural and urban areas.
