一、怎样检测小学语文教学目标的达成度
第一阶段，我们在实验方面，主要进行的是通过目标检测题对一节课的目标达成情况进行检测，本以为这种形式操作性强，可实际操作起来，效果特别不理想。最主要原因是把研究想得太窄了，只是就着专题的名称想，没有拓展思路。而实际上，一堂课的目标达成应贯穿于课堂的始终，单纯以几道检测题来评价目标达成度，非常片面，并且总显得画蛇添足。其局限性具体表现在:
一、目标检测题的检测多针对三维目标中的知识能力目标层面的达成情况，也有部分检测题能够检测出情感态度价值观方面的达成情况，但对过程方法这一目标的达成情况，基本无从评价。
二、语文能力包括听说读写多个方面，课堂教学中，要进行多方面的语文训练，才能切实提高学生的整体语文素养。但目标检测题形式太过单一，检测的内容太过片面，所以，小专题研究应拓宽研究的渠道，力求做到切实有效。
三、语文教学一直强调“教材只是个例子”，“用教材教”而不是“教教材”的观点，而目标检测题与这一观点相悖，因为单一的以目标检测题评价课堂目标达成度，易导致只注重把教材涉及的知识点讲全讲深讲透讲细的结果，这与新课程标准是背道而驰的。
另外，在实际操作中，目标检测题很少当堂完成，变成了课后练习题，这更不能检测教学目标的达成情况，实验似乎陷入僵局。
此时，新一期山东教育如及时雨帮我们解了围。其中的一篇介绍潍坊小学语文“主题学习”的材料引起了我们对自己语文教学的反思。学校组织语文教师学习潍坊市开展的小学语文“主题学习”的做法，要求结合我校的教学实际，结合自己的教学实际，更新观念，大胆借鉴。他们主张 “本色语文、简单语文、返璞归真”。整体规划：低年级大量识字，尽早阅读；中年级课内外结合，拓展阅读；高年级整体推进，主题阅读。老师们通过学习发现了自己教学中存在的少慢差费的问题，决心精心设计课堂教学环节，适当压缩正式教材的上课时间，用推荐阅读来扩大学生阅读量，加强学生语言的积累；二是转变教学方式，由教师的教转为学生的学，让教师教得省力，学生学得轻松；三是激发学生阅读兴趣，培养学生的自学能力和合作技巧，从而增强学生的发展后劲。
紧接着，全市开展了语文课例大教研活动。针对课例大教研中发现的问题，把问题与我们的小专题研究结合起来。使我们的小专题研究让缺乏实效性的检测题变得具有实效性。
如：
对目标检测题的设计中内容偏多，重点不够突出的问题，提出了精当的要求，通过精心设计的检测题来实现它的检测功能。
一、对字词句的检测，不应该面面俱到，而应该突出重点。如何选择这一两个重点词语，我认为文本中那些能够起到牵一发而动全身的作用的词语，才是检测的重点。如《圆明园的毁灭》中，对“不可估量”这一牵一发而动全身的词语，教学设计是这样的：
“圆明园的毁灭是祖国文化史上不可估量的损失，也是世界文化史上不可估量的损失。”
师：有不可估量的损失，就说明它一定有不可估量的价值。请用“……是……也是……”这个句式，说一说。
（“圆明园的价值是祖国文化上不可估量，也是世界文化史上不可估量的！”）
师：昔日圆明园究竟有些什么，使我们说它有不可估量（板书“不可估量”）的价值？学习课文第二、三、四自然段
学完二三四段后，回扣“不可估量”：
请理直气壮地告诉自己以及天下所有的人——“圆明园的价值是祖国文化史上不可估量的，也是世界文化史上不可估量的！”
检测题中，可以这样设计：说说不可估量的意思，用不可估量写一句话，甚至让学生动笔写一写，学完课文后，你对圆周明园的不可估量的价值有哪些了解，或是你对圆周明园的毁灭造成的不可估量的损失，想对谁说些什么，我认为这样设计检测题，才能行使好检测题的检测功能。
二、对于文情并茂、文质兼美的课文，在精心指导朗读的基础上，进行读写结合的开放式检测，效果也很好。如《凡卡》一课的结束部分：
师：爷爷、凡卡、无数受苦受难的穷人，都只能苦苦挣扎在沙皇统治的无形大网之中，小凡卡不知道他的信爷爷收不到，或者即使爷爷收到也不能救他于苦海，可怜的孩子还在做着美梦，让我们一齐读，读慢一点，让可怜的小凡卡的美梦再长些，读得轻一点，别吵醒他。（富有感染力的音乐响起）
师：一封救命信，最终只是一个可望不可即的美梦，9岁的凡卡，生活为什么这么悲惨？课文学到这里，你都想对谁说点什么？把你想说的话写下来。
情到深处自然有很多话想说，这时的写是水到渠成，情之所至，通过这样的课堂小练笔，也能很好地检测出目标的达成情况。
三、抓住读写结合点而进行的小练笔，是检测目标达成度的一种比较有效的方法。除了以上两例中的读写结合，再如学习《地震中的父与子》中，想象阿曼达在废墟下那么长时间里，会想些什么，做些什么，动笔写一写，通过学生的写作情况，能够比较真实客观地反映出目标的达成情况。
二、目标检测xml文件中的difficult是什么意思
代表是否难以识别，0表示易识别，1表示难识别。通常读取时略过这类
三、新课程学习目标检测

Jill and her husband, John, chose the first place because they would have longer time in the water with the dolphins.
At last the day came. With many other people, they saw a video about dolphins and learned a lot about these wonderful sea animals. Then it was time to go into the sea! Jill cried with happiness when she saw the dolphins for the first time.

The dolphins liked to have people near them and no one was scared of them. After one hour, the people left the sea and had a sandwich, then had a rest.
In the afternoon, everyone could go back in the sea and swim for another hour with the dolphins. The teacher showed them how he could speak to the dolphins by using his hands.

Jim went to school to study history, but when he finished his first year, he didn’t pass the exam and the teacher said to him, “You have to leave school.”
When the boy’s father heard this news, he was much worried. He came to the school to see the teacher. He found the teacher in the office and asked the teacher to let Jim go on with his studies the next year.
“He is a good boy. He always does well in history,” said Jim’s father, “and if you let him pass the exam this time, he will do better next year and pass the exam.”
“No, no, that’s impossible!” answered the teacher, “Last month I asked him when Napoleon（拿破仑）died and he didn’t know.”
“Please sir, give him another chance.” said Jim’s father, “You know we don’t have any newspapers in our house, so nobody in our family knew that Mr. Napoleon was ill.”

四、IVS是什么意思
IVS是基于DSP的单路视频编码器，同时内嵌了智能视觉监控功能，其自动检测、即时报警通告和即时视频确认等功能可以大幅提高安全监控水平，同时基于三维视场检测，能自动区分目标种类、大小、速度、移动方向等特征，具有出色的非平坦地形上的目标检测能力，能可靠的检测遥远距离的目标，采用先进的模式识别技术和特定的行为分析算法，保持高检测率(99.9%)的同时只有很低的误报率（少于1个/天）。IVS结合监控摄像机或PTZ球机可对智能视觉分析数据联网进行报警运营，实现“事先预警+事中处置+事后取证”，是“智能视觉+物联网”的真正的物联网。
