This paper answers teacher Zhang's question: What help does the feedback device have to the primary school Chinese? By the way, how do other functions of Ma Jixing Magic Classroom Teaching System help Chinese classroom?

First, the function of the feedback device

Feedback device can be said to be the most important standard of Ma Jixing magic classroom teaching system. It has many functions, such as signing in, voting, evaluating and grabbing power.

? Sign-in is mainly used to check whether the feedback equipment can be used normally and the attendance of students before class. Click the Start button and students can log in. After students sign in, click the end button, which means that the sign-in is over and students can't continue to sign in. For students who sign in successfully, the serial number of the feedback device on the screen changes from red to green. If it is still red, the teacher needs to confirm whether the feedback device is too low to be used or other reasons. If it can't be used, it is necessary to change the serial number that is temporarily useless to the serial number that students need to ensure that students can participate in the class in the next activities.

Voting is the core function of the feedback device. According to the needs of teaching, teachers can set up some multiple-choice questions before, during and after class to find out whether students have mastered some knowledge points and test their learning situation. The choice of questions can be preset by teachers or generated by students on the spot, and then students' thinking can be seen according to the statistical chart of students' voting, so as to understand the real-time learning situation and then decide the follow-up teaching activities. If more than 70% of the students are correct, then choose one person directly from the correct option, explain the reasons for choosing, and simply take it. If 30%-70% of the students choose correctly, we can use the peers in the group to learn, let the students exchange dialogues in the group, and then answer them two or three times as needed. If the correct students are less than 30%, then the teacher needs to explain in detail.

There are two evaluation methods: works evaluation and real-time evaluation. Teachers can upload students' classroom exercises, new words written, videos read aloud and other works to the screen through the Magic Teacher APP, so that students can use the feedback device in their hands to evaluate and score, and promote student-student interaction. Real-time evaluation can evaluate and score students' reading, speaking and group activities in the state of unselected works, and promote students' active participation. Whether it is homework evaluation or real-time evaluation, teachers need to give specific evaluation criteria. Generally, 2-3 sub-items are made according to the needs, and each item has a score of 1-3, so that students can evaluate according to the standard. It is suggested that the total score of the evaluation form for junior children should not exceed 3 points to avoid disorderly scoring.

Grab the right, let students grab the right through the feedback device, the system selects the top three students who press the button first, gets the priority of the current activity, and promotes students to actively participate in the classroom. In teaching, it is not recommended to use the function of grasping power frequently, because only students who can grasp power actively are the objects that teachers should pay special attention to.

? Second, other functions

Ma Jixing's magical classroom teaching system has three other functions: selecting students, timing and grading.

Pick people, you can randomly choose one or more people from the three choices of class, group and group members as needed. Before picking people at random, you should throw out questions or tasks and tell students to answer them by picking people at random, so as to promote all students to actively participate in classroom activities.

? Timing is convenient to control the time of students' activities and can calculate the completion time of students' learning tasks. It is an artifact to manage students' classroom time. Generally used for group activities. Group activities are usually divided into individual independent activities and group exchange activities. Every activity is timed according to the need to promote students to complete their learning tasks effectively and efficiently.

? Grading is a good helper to manage students' classroom performance, which can be given to individuals or groups, encouraging students to take the initiative to participate in the classroom, and promoting the mutual cooperation of members in the group and the sense of competition among groups. It is suggested that small prizes be awarded to the top three outstanding players on the spot according to the scores.

Ma Jixing's magic classroom teaching system is powerful, which can promote students' active participation and help Chinese classroom better. What we need to do is to keep "deliberate practice" in order to make better use of it to serve the Chinese classroom.
