When interviewed by reporters, Wang Dawei encountered such a thing. A university president accompanied the leaders of the Education Bureau to attend a classroom randomly. When the class bell rings, the teacher walks into the classroom and starts the courseware. Half an hour later, another teacher walked into the classroom and asked the other person with amazement. You went to the wrong classroom. This class is mine. The other side was also amazed and immediately left the classroom. Although this kind of thing happened only by chance, but the university classroom teacher said in class, leaving the class, it is common to not know a few students in one semester. It is not uncommon to have a one-way infusion in the middle and high school classrooms that have long been criticized for many years. The “flip classroom†that is frequently mentioned in the middle and high schools to solve this classroom problem is needed by universities. Wang Dawei decided to do some "articles" around the university classroom. In August 2015, he founded Beijing Guojiao Sunac Education Technology Co., Ltd., which is also the class cube. Develop an intelligent teaching interaction and management system for college classrooms. The system includes the class cube system service platform, the teaching interactive console and the WeChat public number. The teaching interactive console is a teacher port installed in the classroom to assist the teacher in classroom teaching. Teachers and students each have a back-end system on the PC side. The student’s port in class is the WeChat public number on the phone. With these platforms and tools, the lesson cubes permeate the various teaching sessions of “before the classâ€, “in class†and “after classâ€. Just making tools is the direction that Wang Dawei took at the beginning. He had done a few years of content before, and felt that it was "too heavy" and relied too much on funds. The tool cube that only serves as a tool gives itself a position to do lightweight classroom application. Under the premise of changing the teaching habits of teachers, it can bring heavyweight to the classroom teaching effect by implementing interactive teaching and establishing a process evaluation mechanism. Change. Large and medium-sized classrooms can also interact quickly Compared with junior high school teachers, a big pain point for university teachers is that the classroom is larger. In a public class, there may be more than 200 people in the class. It is difficult for teachers to establish effective interaction with so many students. It is often the case that the teacher speaks dry and the students below are drowsy. How to make the "low-headed family" look up is a headache for many teachers. In addition to the high-level teaching of the teachers, it is more important for the students to raise their heads, so that students have a sense of participation, that is, the classroom must have interaction. Before the class, the teacher can arrange the pre-study tasks and the effect test after the preview through the teacher-side system of the PC. Students complete the preview tasks in the back office system. The pre-study situation of the students will automatically generate a “pre-school study report†to be provided to the teacher. The teacher has a good idea before the class, and can do precise teaching for the students' difficulties. The interactive console has a rush and answer function. Teachers can put out some discussion questions around the knowledge in the classroom. Students can make public answers and answer in the WeChat public number on the mobile phone. After the answer, the system will automatically appear several evaluation dimensions, the teacher will give an evaluation of the student's answer immediately, and accumulate in the system. In response to the student's response, the system will immediately provide feedback on the statistics to help the teacher dynamically understand the student's knowledge of the knowledge points taught. Attendance in medium and large-scale classrooms is also a problem that plagues teachers. More than a hundred people have passed away after half an hour. Class time is greatly wasted. The check-in function in the interactive teaching console of the class cube is to solve this pain point. When the teacher clicks the check-in function on the interactive console, the system will immediately generate a series of sign-in codes, which will appear on the projector in the classroom. The students enter the sign-in code in the WeChat public number on the mobile phone. At this time, the number of people who checked in will be displayed on the interactive interactive console. The names of students who have not signed in will be displayed in another column. In order to prevent students from arranging each other's “ventilation and reportingâ€, the system also specially set up a reminder of abnormal geographical location. Process evaluation penetrates into the teaching process The system can help teachers set up classroom problems, and can also save time for selecting students to answer questions and make the class more orderly. But how to make students are willing to answer questions proactively is the key to whether the interactive classroom can achieve the desired results. Scores have become the biggest motivation for students. When the evaluation of students no longer only depends on the mid-term and final exams, the behavior of students will naturally change. On the interactive teaching console, each performance of the student in the classroom can be quantified into specific scores, which are finally counted in the total score. Process evaluation is an important part of the classroom system. In the classroom, after the students answer the questions, the teacher can directly give an evaluation on the interactive console, and the system calculates the score based on the evaluation. There is also a small class test, students can receive the questions directly on the WeChat public account, and answer in time. After submission, the system will automatically score points quickly. The teacher can see the test results at the interactive console. Student scores are also included in the system. In addition, in addition to the teacher's score, the system also supports mutual evaluation. When there are group experiments or group work, they can be anonymously evaluated. The evaluation criteria are not limited to the scores of the questions and the correct rate of answering the questions. In addition to these basic items, there will be a flexible adjustment point. If the teacher feels that some students have improved progress, or they have a problem on a certain issue. In insight, you can give a certain score on the adjustment item. In the end, the scores add up to the student's grades. However, this grade is accumulated by one lesson, and the scores are constantly changing. Students can keep track of their scores and relative positions and adjust their learning in a timely manner. The evaluation of the teacher is also a highlight of the class cube. Different from the simple subjective scoring and questionnaires in the past, the class cube can refine the large amount of data generated in each class, providing a more objective and comprehensive assessment for teachers. The class cube has a teaching management system. On this system, you can observe the classroom situation of any teacher, including attendance, classroom activity, and student knowledge. Adapt to user habits to retain users This set of products is directly oriented to colleges and universities and is purchased by the school. In this mode, the number of users grows steadily and users use higher viscosities. Wang Dawei emphasized that the more this is the case, the more the product should be done. The product concept proposed by the class cube is that the lightweight application brings heavyweight changes to the teaching effect, and the operation is adapted to the teaching habits of teachers and students as much as possible, so that the migration costs of teachers and students are minimized. In the beginning, the teaching interactive console was a screen mounted on the podium, similar to a tablet. When Wang Dawei entered the school, he found that the teacher needed to bend over to the screen in order to use the console. He went back and immediately let the R&D department improve. Finally, the interactive console was changed to a stereo machine with a height of about one meter. The teacher can stand and operate without any need to bend over. The WeChat public account on the mobile phone side of the student originally sent the content of the teacher's lecture in the classroom, and then stopped the push. "The class is looking down at the mobile phone, there is no visual communication with the teacher, and the teacher's teaching experience is very bad." Wang Dawei said that the equipment is only a tool, and the product cannot violate the basic teaching rules. Only after you understand the real needs of users can develop products to retain users. The system of the class cube is still being updated. In view of the large amount of teaching real-time data collected by the current system, how to more accurately reflect the teaching effect and provide more objective and detailed teacher and student evaluation information, these are the next considerations of the class cube. The one-year-old class cube has now entered 14 colleges and universities, covering nearly 20,000 students and thousands of teachers. Wang Dawei said that in the next two to three years, the class cube will focus on polishing products, entering more colleges and universities, and expanding product coverage.
