(1) Highlight students' subjectivity
In the past, most of the teaching is based on teachers' teaching, and the teaching reference has also become a sharp tool to solidify teachers' thinking; Students are the passive recipients of knowledge, and the knowledge they have learned cannot be integrated into their specific lives in most cases. Teachers teach knowledge purely for the purpose of teaching, while students learn knowledge for the purpose of exam results. So our students are very deficient in practical application and innovative thinking. Some people say that our teaching is to turn the question mark full of curiosity of students in primary school into a silent comma in middle school and a full stop in college. However, constructivist learning theory believes that knowledge is not an accurate representation of reality, but is dynamic. Therefore, our teaching objectives are not rigid, it has strong flexibility; It should not be imposed on learners, but should be decided through consultation with learners. Therefore, the role of teachers has changed from "Preaching, teaching, and dispelling doubts have become promoters, organizers, and guides. Students' subjectivity has been brought into play. From the perspective of phenomenon, the teaching process is the process of teachers' teaching and students' learning; from the perspective of essence, the process of teaching and learning is the process of teacher-student interaction, and its basic attributes are interactivity and complementarity. Through teacher-student interaction, communication and complementarity, teaching and learning are mutually beneficial. Teachers and students are the main body of the teaching process, and both are Personally, they are completely equal. China's basic education curriculum reform clearly proposes to establish a new teacher-student relationship that fully reflects respect, democracy and development, and requires full attention to and respect for the main body of students, and enhance the way of students' participation, exploration, discovery, exchange and cooperation.
(2) Create learning scenarios
Constructivist learning theory believes that learning is based on the original experience of the subject and actively constructs a new psychological representation process through interaction with the external world. The construction of psychological representation has two meanings: one is the understanding and learning of information. That is, the process of using existing knowledge and experience to reconstruct new information; Second, the reading of existing knowledge and experience is a process of reconstruction, which is easier to construct in specific learning situations. For example, students born in the 1980s and 1990s generally lack knowledge of the Qing Dynasty and the history before and after the 1911 Revolution. In view of this background, which has a large gap between reality and history, it is difficult to achieve the desired effect by literal explanation alone. Therefore, teachers can create learning scenarios when teaching the lesson "Wind Wave" (Yang Ganzhong, College Chinese, Beijing Broadcasting Institute Press, 2002). That is, we can collect some visual data through the media, such as the image of men in the Manchu Dynasty with long braids; Clear up the historical facts of the struggle against the French formulation; The picture data of the hair of the army of Taiwan; Before and after the 1911 Revolution, the trend of wearing dresses and cutting braids, etc. Through these image data, students can have a more comprehensive understanding of the history of "pigtails". More importantly, through these image data, students can be introduced into an unexpected situation: a pigtail actually relates to the life and death of a nation, a country and a nation, and countless people in this country. Such teaching scenes greatly stimulate students' interest in "pigtails", thus promoting them to study, understand and study the learning content with strong interest.
This example of Chinese teaching shows us the role of "scene". Of course, the creation of "scenarios" is diverse. Teachers should create a process conducive to the "growth" of students' knowledge or the reconstruction of new experience according to different disciplines and different students' knowledge backgrounds. It also highlights the communication between school education and the real world.
(3) Attach importance to cooperation in learning
The constructivist learning theory believes that the existence of the world is not independent of the existence of the subject, but begins with the construction of the subject. Each of us has our own way to construct the meaning of the world, so our understanding of the world is diverse. Teachers and students are also independent subjects, and they also have their own ways to construct the world. Therefore, every teacher should recognize the differences of the construction of the world meaning of the subject, but this does not mean that the subjects are not connected with each other and isolated from each other in the teaching process. On the contrary, this difference shows the value of mutual cooperation between teachers and students, and between students and students. Through cooperation, the ideas between subjects are exchanged, collided, integrated and improved, which greatly enhances the effectiveness of learning.
For example, when teaching "Scientific Inquiry" in the first chapter of the seventh grade "Science" (I), the teacher first divided the students into groups. And prepare some boxes with different objects in advance. The objects for people should be as easy to detect as possible. Because it is carried out according to the students' own life experience, the exploration work is relatively simple, and it is appropriate to form a group of four people. Secondly, intra-group division of labor. The division of labor shall be carried out according to the specialty of the students in the group. For example, the students with high composition are "recorders", the students with more courage and strong language organization ability are "reporters", the students with strong action operation ability are "operators", and another student is "inspectors". Third, group experiment and black box exploration. The operator shall take the initiative, the recorder shall record in time, and the inspector shall supervise to complete the inquiry. In the whole process of student group cooperation, teachers must play a guiding role, otherwise the student group cooperation in class will not have a good effect. Teachers can also appropriately motivate students. Fourth, report the experimental results. After concerted efforts, the reporter reports the crystallization of the collective cooperation of the team members. The above case is a group cooperation. Under the guidance of the teacher, the students who are mainly in * are connected by grouping. Through intra-group cooperation and inter-group communication, the enthusiasm of the students is not only improved, but also can achieve good teaching objectives. The students not only give full play to their strengths, but also supplement their deficiencies in some aspects; Through inter-group communication and appropriate competition, students in each group can further supplement their own shortcomings and stimulate their enthusiasm for learning. Of course, during the study period, teachers should make preparations and give students cooperation skills in advance, such as how to organize and listen.
In short, constructivist learning theory poses a great challenge to traditional teaching, and it provides a broader vision for the development of education in the future. The dynamic knowledge view of constructivist learning theory breaks the traditional teaching idea of taking knowledge as the final conclusion, so as to broaden people's thinking and thinking ability, and fully affirms the subject status of individuals; Its learning view creates a harmonious learning atmosphere for students to communicate with each other, and actively constructs. Social interaction and situational nature reflect the process of learners actively constructing information; Its teaching view is to highlight the subjectivity of students and attach importance to their original knowledge and experience. Of course, every theory is not perfect. In the future study and work practice, we need to complete the shortcomings of its theory, so that the theory can better serve the practice.
