课文摘录：
西周时期，农作物种类更加丰富，有粟、稻、黍、稷、麦、桑、麻等，后世的主要农作物多已具备。随着农业生产的发展，人们的生活也从频繁迁徙开始走向定居。中国农业独立发展，自成体系，奠定了中国古代农业社会的基础。
随着农具和生产技术的进步，中国古代农业的耕作方式经历了从集体劳作到个体农耕的变化。商周时期，土地归国家所有，劳动者在田间集体耕作。在工具简陋、生产力水平很低的情况下，这种耕作方式有利于提高工效。
要求：
根据课程标准要求和课文内容，设计出相关的教学过程，包括教学环节，教师活动和学生活动，并说明设计意图。

Who am I?
Over time I have been changed quite a lot. I began as a calculating machine in France in 1642.
Although I was young I could simplify difficult sums.I developed very slowly and it took nearly two hundred years before I was built as an analytical machine by Charles Babbage. After I was programmed by an operator who used cards with holes,I could "think"logically and produce an answer quicker than any person. At that time, it was considered a technological revolution and the start of my "artificial intelligence". In 1936 my real father, Alan Turing, wrote a book about how I could be made to work as a"universal machine"to solve any difficult mathematical problem. From then on, I grew rapidly both in size and in brainpower. By the 1940s I had grown as large as a room, and I wondered if I would grow any larger. However, this reality also worried my designers. As time went by, I was made smaller. First as a PC(personal computer) and then as a laptop, I have been used in offices and homes since the 1970s.
These changes only became possible as my memory improved. First it was stored in tubes, then on transistors and later on very small chips. As a result, I totally changed my shape. As I have grown older I have also grown smaller. Over time my memory has developed so much that, like an elephant, I never forget anything I have been told! And my memory became so large that even I couldn't believe it! But I was always so lonely standing there by myself, until in the early 1960s they gave me a family connected by a network. I was able to share my knowledge with others through the World Wide Web.
Since the 1970s many new applications have been found for me. I have become very important in communication, finance and trade. I have also been put into robots and used to make mobile phones as well as help with medical operations. I have even been put into space rockets and sent to explore the Moon and Mars. Anyhow, my goal is to provide humans with a life of high quality. I am now truly filled with happiness that I am a devoted friend and helper of the human race!

材料：
刘老师从师范学校毕业后，在一所乡村中学开始了她的教师生涯。三十年来，她一直坚守在乡村教学的第一线。
为了寻找学生观察的野花，刘老师在河岸、田埂间精心识别、挑选；为了让学生能更好地体味课文蕴含的情感，在家人熟睡的时候，她还一个人在厨房里反复朗读课文。大雪过后，她会兴致勃勃地带学生去找腊梅，去看苍翠的“松树公公”，让学生更好地感受自然。
刘老师坚持每天黎明即起，坐在校园旁的荷花池畔背唐诗、宋词，背郭沫若、艾青、普希金、海涅、泰戈尔等中外名家的诗篇，用优美的诗篇来陶冶自己的情操。她摘抄的古今中外的优秀诗篇，有厚厚的几本，她还如饥似渴地学习教育学、心理学和美学的相关知识，阅读许多中外教育名著，撰写日志，不断改进自身的教学实践。
问题：
请结合材料，从教师观的角度评析刘老师的教育行为。（14分）
