The general process of information acquisition Sharing information acquisition is the content of the second chapter of Information Technology Foundation. Starting from this chapter, our information technology course teaching is mainly based on practical operation, and the network information retrieval in information acquisition needs to be taught in the network environment. At present, there is no computer room in the first year of senior high school in the new campus, so we can only use classroom multimedia for classes, which is much better than the simple dictation of teachers before, and it can also save the time for teachers to write on the blackboard.
When preparing lessons for this section, I chose the story that Yang Shuzi, an academician of China Academy of Sciences, was sent to Xianning Farm in Guizhou for labor reform in the late 1960s. One night, the leader asked him to play pig grass and pig dishes the next day. This may be difficult for this mechanical engineering expert. He didn't raise pigs, didn't do any work in this field, didn't know which is pig grass and which is pig food, didn't have books on raising pigs in his hand, and couldn't ask poor middle peasants for advice, which made him very embarrassed. That night, Yang Shuzi tossed and turned, and finally came up with a coup. Through this story, I ask students to find out what is the key point of information from the story, that is, what is the purpose of information demand? The students soon found the answer: how to fight pig grass and pig food? Through this story, students can easily understand the general process of information acquisition, including the determination of information needs, the choice of information sources, the determination of information acquisition methods and the evaluation of information. Finally, I quoted another recruitment message in my summary:? A very attractive big company recruited 10 employees. Xiao Li, a college student, went to apply, but was told that the recruitment had ended for two days and the staff was full. When Xiao Li consulted in the company's personnel department, he found that many college students kept coming to consult and the company's personnel department was also very busy. After thinking, Xiao Li got a useful message from it and was hired by this big company. ? Ask the students to find information from this lesson and find the information needs. Judging from the students' answers, the fundamental reason for students' low grades is that most students will not take the initiative to think and pass on knowledge. I don't even think the question I asked has anything to do with the content of this class, and I don't know where to consider it.
In fact, I quote these two seemingly simple stories as the teaching content of this class, and the main purpose is to inspire and guide students to think through stories. The previous theoretical class has told you many similar stories, but the students have never been able to connect. Listening to a story only pays attention to the plot, not the moral of the story itself.
The general process of information acquisition teaching experience sharing After this lesson, let students understand what is the key to obtaining information. The way of information source, the diversity of information source, and the appropriate ways and means of obtaining information. This is more important than simply introducing the search for information from the Internet. In other words, our teachers who teach information technology courses should not only let students find information from the Internet better, but also cultivate people's information awareness and improve people's information literacy. This is also the goal of information course, to cultivate students' information literacy. Let them know that on different occasions, they will choose appropriate, efficient, convenient and fast information acquisition methods to obtain useful information.
In fact, the key to obtaining information is to let students have an open mind and a more conscious awareness of facing information, which is also reflected in textbooks. Because this section is a pure theory class, should it be removed from the class? Preach? This method can make students experience the process of information acquisition personally, and has a strong influence on the comparison of information acquisition methods, which can make students further understand the significance of information acquisition. So in class, I not only explained to them how Liu Lei got the weather, but also let them know how to go to a computer store to learn about buying a computer and how to get information. Being confined to the classroom will make students misunderstand. Although there are various ways to get information, the network is still the most convenient one. Students often think that information is obtained through the internet, so it is difficult for such teaching to jump out of the strange circle and get rid of people who don't know. Baidu? In this case, the network is the only way to get information.
In teaching, we should provide some comparisons for students to obtain information by enumerating real-life examples. Only in this way can students understand that the information obtained from the network is limited, and it is difficult to ensure the accuracy and effectiveness of the information resources that can be found from the network. Because different network editors have their subjective views, they can't represent the original meaning of information and cultivate their consciousness.
I realize that the key to effective teaching is the change of teachers' concept. If students want to move completely, they must put forward higher requirements for teachers. There are also many problems in the teaching process, such as? Academician Yang Shuzi beats pig grass? Sensational examples are not enough, and mutual evaluation between groups needs to be further strengthened.
Through the teaching of this course, I gained a lot and reflected deeply, which laid a good foundation for my future teaching. I believe I can take this opportunity to better carry out teaching and make every student gain something.
