本研究基于人教版、北师大版、苏教版各12册的小学语文教材生字表（识字表、写字表）的编排和汉字特征信息进行了量化研究，结果发现，人教版最符合《新课标》常用汉字、基本字学习要求；对平衡语料库高频汉字的学习安排合理，完全覆盖累积频率75%的汉字，基本覆盖90%及以上累积频率的汉字，且高频字较为集中地出现在第一学段。北师大版对累积频率90%以上高频汉字覆盖率高，但学习进度没有明显的集中趋势；苏教版未完成《新课标》对基本字的学习要求，对高频汉字覆盖出现疏漏。对人教版教材汉字特征信息的分析发现，随年级增长，汉字的侧重学习类型由象形字转向形声字，汉字视觉复杂程度、形音对应规律性、形义对应透明度均有所提高：由一年级至六年级，生字笔画数增多的同时，读音和字义都呈现与字形更加相关的规律性。

This research conducted a quantitative description on the characters selected to be explicitly taught in elementary school Chinese, and analyzed the properties of 2999 characters by their visual complexity, type, phonetic regularity and semantic transparency. Among the three versions, the textbook published by People’s Education Press finishes teaching the characters listed in the New Curriculum Standard the best, with all the basic characters finished in early grades and most of the common words along six years. It also covered all the 75% and most of the 90% high frequency characters based on the Cncorpus published by State Language Commission, with the most commonly used characters occurring assembly in the first two years. Relatively, the textbook published by Beijing Normal University Publishing House includes the most of the high frequency characters but not as assembly as the former. Textbook published by Jiangsu Education Press performs omissions on teaching the basic and high frequency characters explicitly. The research on the properties of characters taught in textbook by People’s Education Press has shown that there is an increase in the visual complexity, phonetic regularity and semantic transparency of the characters from earlier grade to later, with the increase of transparency more apparently than that of the phonetic reglarity; the number of pictographs increases and that of phonograms decreases during elementary school.
