生物教科书作为生物课程内容的主要载体，在中学生物学教学中起着至关重要的作用。随着基础教育改革的进一步推进，教科书迎来了多样化的时代。为了使生物教科书更好地服务于教学，也为了更加全面地提高学生科学素养，对教科书的研究和分析工作就体现出其必要性和重要性。目前对教科书的分析呈现了多角度、多维度的态势，其中对教科书的连贯一致性研究已经成为国际科学教育的一大热门领域，是美国“2061” 计划的一项核心任务。美国科学促进会使用研制的教科书内容连贯一致性分析工具对国内的多本高中生物教科书进行连贯一致性分析，并公布了各本教科书的分析报告。“2061”计划评价工具对教科书的研究比较深入，具有很强的借鉴意义。 本研究采用文献研究法、内容分析法等，以我国的生物学课程标准为本土化的重要依据，对美国“2061”计划中使用的教科书内容连贯一致性分析工具进行本土化，并利用该工具，依据相应的评定指标，对我国现行人教版高中生物教科书中的“自然选择与进化”部分的内容进行内容连贯一致性分析和判定，并在论文的研究成果部分对人教版高中生物教科书中的“自然选择与进化”部分的连贯一致性进行具体分析和描述。最后对教科书中有关“自然进化和选择”部分内容的编写以及教师的课程设计提出建议。

As a main carrier of course content，biology textbooks play an extremely important role in highschool biology course-teaching. With the further advance reform of education,textbooks are facing an era of diversification.In order to make biology textbooks as the better servicers of course-teaching,as well as to improve the scientific literacy of students more fully, research and analysis of textbooks reflected to be required and important. At present,analysis of textbooks present in multi-ways and multi-dimension, and among the ways,the research of textbooks’ coherence is an popular area in the world, its a key task for Amercia “2061”Project. AAAS used a set of coherence-analysing tools to analysis the coherence of several high-school biology textbooks,and then announced the analysis report of each textbook.The research of analysising the coherence of textbooks which use coherence-analysing tools is in great depth,and has a strong reference value. This study localize the coherence-analysing tools of “2061”Project based on the biology curriculum standards of our country by means of literature reviw and content analysis,and then use the tool to analysis the “Natural Selection and Evolution” part of the PEP version highschool biology textbooks according to the evaluation index.Besides, this study describes the results of analysising txtbooks in detail.Lastly,this study provided some suggestions for textbook writing and teacherers’ curriculum designing.
