The qualification of a preschool teacher is one of the important factors that determine the quality of preschool education. To increase the quality in education, teachers should be equipped with the necessary knowledge starting from pre-service training, and in-service training should support the upgrading of their knowledge. Thus, the aim of this study was to develop an e-Mentoring-Based Education Program (e-MENTE:PT) for preschool teachers and to test its effectiveness on their professional development during the in-service support period. The study used a design-based research approach. First, focus group interviews were conducted with one-hundred-and-five preschool teachers to find out their needs. Then, an e-MENTE:PT Program was developed based on these needs and devised to be used on the Canvas learning management system (LMS), which involves all opportunities of e-learning and allows one-to-one e-mentoring. The e-MENTE:PT Program involved twelve modules related to the pedagogical content knowledge of the preschool education program. Each module included contents, goals, module materials, e-books, videos, pre- and post-module evaluation questions, discussion questions, live lessons and e-portfolios, all of which were integrated in the LMS. Next, eighteen full-time and nine substitute voluntary teachers from five different provinces were selected as mentees by means of criterion sampling. Nine academicians working in these provinces acted as mentors and implemented the application, each working with two mentees for two months. Qualitative data were analysed by means of descriptive analysis and quantitative data were analysed by means of the Wilcoxon signed rank test. The research concluded that the e-MENTE:PT program supported preschool teachers’ professional knowledge, learning environments and classroom applications, and an e-mentoring based teaching management system was effective on professional development.

幼儿教师的资质是决定幼儿教育质量的重要因素之一。为提高教育质量，教师应从岗前培训开始掌握必要的知识，在职培训应支持知识的升级。因此，本研究的目的是为学前教师开发基于电子指导的教育计划 (e-MENTE:PT)，并测试其在在职支持期间对其专业发展的有效性。该研究使用了基于设计的研究方法。首先，对一百零五名幼儿教师进行了焦点小组访谈，以了解他们的需求。然后，根据这些需求开发了一个 e-MENTE:PT 程序，并设计用于 Canvas 学习管理系统 (LMS)，这涉及电子学习的所有机会，并允许一对一的电子指导。e-MENTE:PT 计划涉及与学前教育计划的教学内容知识相关的十二个模块。每个模块包括内容、目标、模块材料、电子书、视频、模块前后评估问题、讨论问题、现场课程和电子档案，所有这些都集成在 LMS 中。接下来，通过标准抽样的方式，选择了来自五个不同省份的 18 名全职教师和 9 名代课志愿教师作为学员。在这些省份工作的九位院士担任导师并实施了申请，每位院士与两名学员一起工作了两个月。定性数据采用描述性分析，定量数据采用Wilcoxon符号秩检验。
