",="" "pingfang="" sc",="" "hiragino="" sans="" gb",="" "microsoft="" yahei="" ui",="" yahei",="" arial,="" sans-serif;="" overflow-wrap:="" break-word="" !important;"="" align="justify">作为一名教师,请你谈谈对“立德树人”的理解。

",="" "pingfang="" sc",="" "hiragino="" sans="" gb",="" "microsoft="" yahei="" ui",="" yahei",="" arial,="" sans-serif;="" overflow-wrap:="" break-word="" !important;"="" align="justify">【参考答案】

",="" "pingfang="" sc",="" "hiragino="" sans="" gb",="" "microsoft="" yahei="" ui",="" yahei",="" arial,="" sans-serif;="" overflow-wrap:="" break-word="" !important;"="" align="justify">“立德树人”的本意是指自身树立德业,给后代做榜样,培养人才。它强调把“立德”摆在第一位,是因为万事从做人开始,且强调了培养人才是长远之计。“立德树人”是我国历代教育共同遵循的理念,党的十八大报告中也明确说明把立德树人作为教育的根本任务,着力提高教育质量。

",="" "pingfang="" sc",="" "hiragino="" sans="" gb",="" "microsoft="" yahei="" ui",="" yahei",="" arial,="" sans-serif;="" overflow-wrap:="" break-word="" !important;"="" align="justify">第一,“立德树人”要求教师认真践行教师的职业道德规范。教师要善于抓住学生的心理特征,对学生的个性品质加以正确引导;在日常的教学实践中,将情感态度与价值观的维度目标细心体现;在课堂上,给予学生更多名人事迹的熏陶与指引,使学生树正德、立志向。

",="" "pingfang="" sc",="" "hiragino="" sans="" gb",="" "microsoft="" yahei="" ui",="" yahei",="" arial,="" sans-serif;="" overflow-wrap:="" break-word="" !important;"="" align="justify">第二,“立德树人”要求教师必须坚持德育为先,促进学生全面发展。“德者,才之帅也。”学校要从课程德育、社会实践和学校文化三方面进行建构,要把德育渗透于教育教学的各个环节,贯穿于学校教育、家庭教育和社会教育的各个方面。

",="" "pingfang="" sc",="" "hiragino="" sans="" gb",="" "microsoft="" yahei="" ui",="" yahei",="" arial,="" sans-serif;="" overflow-wrap:="" break-word="" !important;"="" align="justify">第三,“立德树人”要求教师必须坚持培育学生健全人格。教师要培养学生积极的心理品质和乐观向上的品格,学会创造幸福,分享快乐;关注学生的内心世界,塑造学生纯真完美的心灵;加强学生心理辅导,认真发掘健全人格教育资源,重视对学生的人文关怀,营造良好的师生关系、同学关系,为培育学生健全人格提供良好氛围。

",="" "pingfang="" sc",="" "hiragino="" sans="" gb",="" "microsoft="" yahei="" ui",="" yahei",="" arial,="" sans-serif;="" overflow-wrap:="" break-word="" !important;"="" align="justify">总而言之,教师应努力投身教育,立德树人,着力提高教学质量,践行职业道德规范,让每一个学生都能成为有用之才。

",="" "pingfang="" sc",="" "hiragino="" sans="" gb",="" "microsoft="" yahei="" ui",="" yahei",="" arial,="" sans-serif;="" overflow-wrap:="" break-word="" !important;"="" align="justify">我的问题回答完毕,谢谢!
