Embodiment two:

Micrologger with LED light.

The difference between this embodiment and Embodiment 1 is that a dimmer is added.

Referring to FIG. 6 , the dimmer is connected between the second switch and the LED lamp 5 , and the dimmer has two groups of dimming devices respectively connected to a soft light 501 and a strong light 502 . A dimming button is arranged outside the folding bracket 1 .

The application of the micro-logger is more flexible.

Embodiment one:

An interactive teaching system.

Referring to Figure 8, the teaching system includes a teaching host, a wireless receiver, a projector, a speaker, and a micro-recorder installed in the classroom.

The wireless receiver is connected to the teaching host, the projector is connected to the teaching host, the speaker is connected to the teaching host, and the teaching host is connected to the teaching server. The teaching server is connected to the big data platform. It is also possible to replace the projector with a liquid crystal display, connect the liquid crystal display to the teaching host, and use the liquid crystal display to display images.

After the micro-recorder is configured on the desks of the students in the classroom, the teaching system becomes an interactive teaching system. After the students turn on the micro-recorder in class, the micro-recorder is paired with the wireless receiver to establish a connection with the teaching host. Point the camera at your desktop, display your completed homework, paintings, etc. on the desktop, or demonstrate the solutions to the exercises on the spot; in addition, in the experimental class, after the students point the camera at the experimental equipment, they can conduct experiments on the spot.

The micro-logger collects the picture information on the desktop and the sound information near the desktop in real time, and then the micro-logger sends out the collected information and data as wireless signals. After receiving the wireless signal, the wireless receiver demodulates the wireless signal and decodes the data, and converts the information in the wireless signal into a data signal that can be recognized by the teaching host. The data signal is sent to the teaching host, and the teaching host will receive the The data is restored into video signal and audio signal, the video signal is sent to the projector, and the projector projects a picture on the projection cloth; at the same time, the audio signal is sent to the speaker, and the speaker emits sound.

In this way, other students and teachers in the class can see the presenter's homework, drawings, and experimental operations on the projection cloth. This will change the traditional teaching method. For example, in the traditional teaching mode, the teacher needs to look through the homework of each student to check the completion of the students' homework, which will take up more time and take up valuable teaching time; After the interactive teaching system, students can open their homework in advance, each student will show their homework in front of the micro-recorder in order, and the teacher can see the completion of each student's homework by standing on the podium through the teaching host or projection cloth , which will shorten the time spent checking assignments and save valuable teaching time. For another example, in the traditional teaching mode, the teacher will select students to come to the stage to solve problems. Some students will inevitably be nervous on the stage, which will affect their normal performance. With this interactive teaching system, students do not need to leave their seats and are less likely to feel nervous , the students who are selected can use the micro-recorder on the desk to demonstrate their problem-solving process, and the students sitting next to them can also help the demonstrator when they encounter difficulties, so that there will be no embarrassment of "isolation and helplessness". The display method can help keep the classroom clean because there is no need to write on the blackboard. For another example, in a traditional experimental class, when the teacher or a certain student performs the experimental operation on the spot, other students can only see the operation process by surrounding the operator, and the shorter students standing outside the crowd cannot see it. In the operation process, under this mode, the quality of teaching is difficult to guarantee. In addition, for some dangerous experiments, both visitors and operators are in danger. With this interactive teaching system, the operator can use the micro-recorder to shoot the operation process, and the teacher and other students can watch the screen on the projection cloth at their respective positions, so that all students in the classroom can see the operation process, The safety of visitors is also guaranteed.

While the micro-logger sends the collected data to the teaching host, the teaching host sends the received data to the teaching server, and the teaching server stores the received data and uploads the data to the big data platform.

When the teacher cannot go to the classroom to teach in person, he can also use the micro-recorder to prepare lessons in advance. After the teacher connects the micro-recorder to the teaching server outside of the classroom or after class, he uses the micro-recorder to record the teaching content. The teaching content is stored in the teaching server and uploaded to the big data platform. After class, the absent teacher entrusts others to operate the teaching host to access the recorded content stored in the teaching server, and students can learn normally by watching the recorded content. In this way, the absence of the teacher will not have too much impact on the teaching.

In addition, when a teacher or student in one classroom makes a demonstration, students and teachers in other classrooms can also obtain the demonstration content in the classroom from the teaching server through the teaching host in their own classroom, thereby enhancing the interactivity of teaching.

After connecting the teaching servers of each school to the big data platform, the teaching server of one school can obtain the content uploaded by the teaching server of another school from the big data platform. In this way, the mutually beneficial sharing of teaching resources can be realized, the utilization rate of teaching resources can be improved, teaching advantages can be complemented, and the overall improvement of teaching level can be promoted.

Embodiment two:

An interactive teaching system.

The difference between this embodiment and Embodiment 1 is that a handheld terminal is added.

Referring to FIG. 9 , the handheld terminal includes a mobile phone and a tablet that are communicatively connected to the big data platform.

By building a teaching service platform and developing a dedicated APP on the basis of a big data platform, users install the APP on their mobile phones or tablets. On the APP, you can watch the content on the big data platform.

For example, when students are unable to attend class, they can use mobile phones and tablets to obtain classroom content (classmates' presentations, teacher's lesson preparation, etc.) from the big data platform at home. In this way, students who are absent from class can study by themselves outside the classroom, and their learning progress is not easy to fall behind.

In addition, parents can use their mobile phones or tablets to access the big data platform to obtain the lesson preparation content of their children's teachers and the demonstration content of the students, so as to understand the teaching quality of the school.

The teaching quality management team can visit the teaching server or big data platform to conduct spot checks on the teaching content, so as to discover teaching problems in time and ensure the quality of teaching. Compared with the quality inspection method of listening in, it is obvious that using this interactive teaching system to monitor the teaching quality is more cost-effective and can achieve good results.

This kind of interactive teaching system teaching is interactive and interesting, which can improve the teaching quality and reduce the teaching cost.

The above descriptions are only preferred implementations of the present utility model, and the protection scope of the present utility model is not limited to the above-mentioned embodiments, and all technical solutions under the idea of the present utility model all belong to the protection scope of the present utility model. It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
