目前,国内的幼儿园教师在职培训大多采取大规模集中培训的方式,在短短的一两周时间内,成百上千人集结一地,聆听专家报告、观摩优质幼儿园。在这样的培训中,听讲座与做记录成为培训学员主要的学习方式。因此,学员们都感到在培训时貌似学了不少,回到工作岗位却一切照旧。于是,不少专业人士批评这类在职培训“缺乏实效”。在美国内布拉斯加大学林肯分校,我们接触到一个教师专业发展项目“早期数学教师专业发展营” At present, most on-the-job training of kindergarten teachers in China adopts a large-scale intensive training. In just a week or two, hundreds of people gather to listen to expert reports and watch high-quality kindergartens.
