Description
Technical field
The invention belongs to education sector field, relate to a kind of classroom instruction response poll means of communication.
Background technology
Present Domestic classroom teaching, the management of school to teacher, student and classroom is all generally adopt to think management, the particularly teacher management to student.In classroom, teacher has absolute power.Classroom becomes the place that teacher carries out solo substantially, and student is rejected as an outsider.This situation determines that class management can only be teacher-centered.The obedience of student to Teachers'Authority be definitely and should, and think that academic dress is from teacher, teaching just can successfully be implemented, and just can complete the task of transmitting knowledge to student.Just under the authoritative thought of this autocracy is guided, part teacher is centered by oneself, show the management mode of "; a pipe is many " from top to bottom, on classroom between teacher and student, substantially do not exchange between student with student, teacher thinks that peace and quiet are the prerequisites ensureing that classroom activity is effectively carried out.This pattern makes student submit to the authority of teacher, must cause following blindly and supertition, and its direct result is exactly that student lacks originality, entity.
Secondly, the inertia of people can be given the style of study of school too, be taught wind to bring extremely bad impact.Partial students is late for class, and operation is plagiarized, and examination is not reviewed, and inertia directly affects the style of study of student; Some teachers' instruction PPT does not upgrade for many years, teaching style is unalterable, after class not with student's interaction, this is also that inertia is done mischief.
The fast development of infotech, infotech incorporates to impart knowledge to students and be applied to classroom instruction becomes the development trend of educating now.The relevant education software such as remote teaching, on-line study, networked teaching management and teaching product increasingly mature, but it is interactive not high, and this just needs to have more interactive Informalized teaching.Although information-based interactive teaching is progressively brought into use in classroom, instantaneity, effective in be also short of to some extent.In prior art, classroom instruction extensively adopts a teacher simultaneously in the face of the pattern of multidigit classmate, and teacher is difficult to the state understanding each classmate in real time, is difficult to assess teaching efficiency.Existing interactive teaching technology, can the information of bi-directional less, the actual needs of classroom instruction can not be met.
How to improve the innovation ability of student, the ability of practice, independent acquisition knowledge and autonomous problem-solving ability, change the passive acceptance of student, do not like the bad study habit of query, not initiative thinking, the initiative of effective raising student is the main contents of prior art research.
Therefore, a kind of classroom instruction is needed to reply the poll means of communication to solve the problem.
Summary of the invention
The object of the invention is the shortcoming for classroom instruction in prior art, provide a kind of classroom instruction to reply the poll means of communication.
For achieving the above object, the classroom instruction response poll means of communication of the present invention can adopt following technical scheme:

1), setting student terminal quantity N, the student terminal being respectively different is numbered;
2), classroom terminal sends answer order to the student terminal of numbering i and judges whether the student terminal of numbering i replys answering information, wherein, answering information comprises the numbering of student terminal, answer and communication mark information, described communication mark information comprises communication success status and communication failure state, and the original state of described communication mark information is communication failure state;
3) if the student terminal answer success of numbering i, then carry out step 4); If the student terminal answer failure of numbering i, then go to step 8);
4), successful for answer student terminal quantity is increased by one;
5), the answering information of the student terminal of numbering i is sent to classroom server by teacher's terminal;
6), the communication mark information of the student terminal of numbering i is revised as communication success status;
7) in the server of classroom, upgrade the answer result of the student terminal of numbering i;
8), according to the communication mark information of the student terminal of numbering i, judge whether answer success, if communication mark information is communication success status, then represent answer success, if communication mark information is communication failure state, then represent answer success;
9) if answer success, then i=i+1 is made; If answer failure, then wait for the S time, then make i=i+1;
10), every the S time, step 2 is repeated)-9).
Further, step 10) described in the S time be 20ms.
Further, described classroom instruction answering system also comprises Cloud Server, and described classroom server connects described Cloud Server.
Further, described student terminal comprises key-press module and calling module, and described calling module connects described teacher's terminal by wireless network.
Further, described answering information is roll-call information, and described roll-call information comprises the numbering of student terminal, roll-call information and communication mark information.
A kind of classroom instruction student terminal power-saving method, adopts the classroom instruction response poll means of communication described in any one of claim 1-5,
Student terminal is economized on electricity by sleep standby method, and described sleep standby method comprises the following steps:
One, when the student terminal of numbering i receives the information that classroom terminal sends, judge whether the information that the student terminal of numbering i receives is effective information, the numbering x of the student terminal in described effective information and information is identical with numbering i;
If two numbering x are identical with numbering i, then the student terminal of numbering i sends answering information to teacher's terminal; If numbering x and numbering i are not identical, then student terminal dormancy, and the length of one's sleep calculating student terminal according to following formula:
Wherein, T
sleepfor the length of one's sleep of student terminal, i is current student terminal numbering, x be teacher's terminal send information in student terminal numbering, S repeats a step 2 in the response poll means of communication of teacher's terminal and student terminal)-9) interval time, N is the sum of student terminal;
Three, make i=i+1, and repeat step one and two.
Beneficial effect: the classroom instruction response poll means of communication of the present invention adopt classroom instruction answering system, classroom instruction answering system adopts wireless communication mode, realize the communication between teacher's terminal and student terminal, acknowledge communication mode between classroom terminal and student terminal adopts polling communication, effectively can improve communication efficiency.
