使用木偶：从学生的自尊心转变口语能力

本文报道了一项研究的结果，该研究涉及以下方面：1）在演讲中木偶与图画之间的差异，2）自尊心高的学生与自尊心低的学生之间的差异，3）教学媒体之间的互动和自尊。样本分为两节课，即使用Puppet讲授的实验课和使用Picture讲授的对照课。每个班级分为两组，每组由具有高自尊心的学生和具有低自尊心的学生组成。为了收集数据，使用了两种工具，即口语测试和自尊问卷。然后，使用描述性统计数据描述研究数据和推论统计数据（即方差ANOVA 2x2的多因素分析和Tukey检验）以检验假设，从而对数据进行分析。这项研究的结果是：（1）木偶比教图片更有效。（2）自尊心强的学生的口语能力要比自卑心智的学生的口语能力强；（3）教学语言与学生自尊在口语教学中存在相互作用。根据研究结果，可以得出结论，木偶是在2014/2015学年向三宝垄摄政中学之一的八年级学生讲课的有效媒体。媒体的有效性受自尊心的影响。（3）教学语言与学生自尊在口语教学中存在相互作用。根据研究结果，可以得出结论，木偶是在2014/2015学年向三宝垄摄政中学之一的八年级学生讲课的有效媒体。媒体的有效性受自尊心的影响。（3）教学语言与学生自尊在口语教学中存在相互作用。根据研究结果，可以得出结论，木偶是在2014/2015学年向三宝垄丽晶其中一所初中八年级学生讲课的有效媒体。媒体的有效性受自尊心的影响。
