This paper introduces the function, price, practicability, advantages and disadvantages of BBK family education machine.
1, intelligent answer: the question bank is incomplete. Take senior one mathematics as an example. After scanning with a scanning pen, it will immediately turn to search. However, after the search, the scanned original questions will not be retained, and the content of the questions with and without borders will come out directly. For example, if an evaluation equation is simplified, then the question is a short answer. Machines can only search for problems in mathematics, science and chemistry (physics and chemistry have never been tried);

2. Taking photos to answer questions: The propaganda says that "5000 teachers answer difficult questions online, and the teacher gives the idea of solving problems within 15 minutes", but after the actual photos are uploaded, it takes nearly 6 hours for a simple equation to get the answer (how many 6 hours does a child have to wait for a reply to a question when doing homework? )。

3. Synchronous textbooks: The textbooks are incomplete, and the seventh-grade English is not available in Beijing Normal University Press, so the seventh-grade English textbooks of People's Education Edition and Yilin Oxford Edition are used instead. However, I didn't see the function of "reading without textbooks (not reading), going out to study anytime and anywhere (not seeing the original content)", and only after consulting customer service did I know that this function was only for primary school textbooks.

4. Learning diagnosis: In learning diagnosis, there are cases where correctly answered questions are regarded as wrong questions. After the analysis is started, the problem and analysis are still misjudged.

5.H 10 only has the function of adding one more pen than H9, and its price is higher than that of 700 yuan. However, this pen can only be used to answer the questions in the secret volume and the synchronization tutorial paper. Be concise before the exam, and the questions of famous schools can't be answered directly on the computer with an electromagnetic pen. The customer service explained that "the calculation questions need white paper or machine calculation". This kind of pen can only be used on the test papers of dense papers and synchronous courses, and its cost performance is too low. Moreover, there is no jack for inserting the pen on the machine, and the pen can only be installed on the standard shell, which is very inconvenient.

Advantages of this machine:

1, the machine runs faster and does not jam.

2. The text scanned by the scanning pen is accurate;

3. Some topics can be searched for corresponding questions, and the search speed is very fast. Some have micro-video analysis (only mathematics);

4. It took a long time to answer the questions by taking photos, but there was still a reply in the end (the test was a simple topic, and there was no difficult topic);

5. The examination papers of the secret volume and the synchronous course can be made directly on the computer, and the draft can be made directly. This function is very practical, and it is also very convenient to find a draft paper to draft when doing the problem.

6, battery life can be, after all, it is 6000MAH configuration.

Machine shortcomings and suggestions:

1, scanning pen jack, charging jack * *. After a long time, the battery life is weak, so you can use it while charging. Because the jack is occupied, the scanning function cannot be used, which reduces the functional use of the machine. Therefore, it is necessary to add a power socket.

2. The electromagnetic pen has no special pen slot on the machine. If the shell is not used, the pen is easy to be lost, and it is necessary to add an electromagnetic pen slot;

3. The propaganda reading function can only be aimed at primary school textbooks, and the reading function of words in junior and senior high school textbooks should be added, like visual repetition;

4. Do the problem on the machine with an electromagnetic pen. When writing with a pen, the hand will also scratch the machine. A function switch that can turn pen writing and handwriting on and off should be added. When writing with pen, handwriting can't be done by hand drawing, so the screen writing is cleaner;

5. Add Xunfei voice input method. Handwriting, Chinese, English and voice input do not need to be switched, which is faster than sogou input and improves the use speed;

6. The updating speed of question bank needs to be faster, the function of searching questions needs to be strengthened, the speed of taking pictures and answering questions needs to be improved, and the learning and diagnosis function needs to be improved and corrected;

7. In the synchronous classroom, it is necessary to increase the content of the teaching materials of the synchronous course itself, so that students do not need to bring teaching materials, and computers can be used as teaching materials.
