This study aims to test the development of basic motor skills of preschoolers according to TGMD -2 ,and assess the reliability and validity of TGMD -2 in preschoolers’ education .Researchers of this study test the performance of preschooler’ s gross motor development by experimentation ,and analyze the data with mathematical statistics .The result demonstrates a relatively high reliability and validity of TGMD -2 in this study which means that TGMD -2 is basically applicable to the test of domestic preschoolers’ gross motor development ,although the total scores of domestic preschoolers are lower than those in developed countries .Samples in this study display good performance in body movement skills while their operation skills are on a relatively low level .Gender and age differences are also revealed .Generally ,boys are more skillful than girls ,and elder ones are more adept than younger ones .Besides ,the paper also proposes other possible perspectives to the study of TGMD -2 ,for example:study of TGMD-2 on samples of different physical development ,study of TGMD -2 on samples with difficulties on motor development ,study of the scorer’s reliability in TGMD -2 and study of the construct validity of TGMD -2 ,etc .%研究目的：本研究通过粗大动作发展量表（TGMD －2）测试学前儿童基本动作技能发展，验证量表在学前儿童中使用的信效度。研究方法：通过实验法测试学前儿童粗大动作发展水平，采用数理统计法对数据进行分析处理。研究结果：粗大动作量表（TGMD －2）在本研究中表现出较好的信效度，其中身体移动技能分值较高，物体操作技能分值较低，年龄组与性别不同呈现得分差异。结论：TGMD －2量表基本适合国内学前儿童粗大动作发展测试；测试总分与发达国家相比偏低，物体操作技能测试结果优于身体移动技能；相比较女童，男童表现出更高的粗大动作发展水平与更熟练的基本动作技能；大龄组粗大动作水平明显高于小龄组。建议：后续研究应扩大样本选取的范围，采用分层抽样的方法进行更为深入细致的研究；建议对不同身体发育水平及动作发展有障碍的学前儿童采用粗大动作量表的测试指标进行针对性实验，验证干预效果；本次研究对量表的组成信度、收敛效度及区别效度进行了验证性分析，建议在后续研究中对评分者信度及量表的建构效度进行验证。
