Description

Wireless classroom TQA device

Technical field

The utility model relates to a kind of teaching servicing unit, specifically is a kind of wireless classroom TQA device.

Background technology

In recent years, along with the quickening of Classroom Information reform step.The teacher of institution of higher education is badly in need of a kind of effective means, in the limited instructional blocks of time in classroom, obtains the student at once situation is grasped in the content of courses; And to the data that the student reports situations, add up in time and handle, realize assessment to the teaching classroom quality.Meanwhile, the student also wishes and can express the satisfaction of oneself in court to teacher's teaching behavior.But Classroom Teaching assessment at present, mode such as generally put question to selective examination or fill in questionnaires is carried out, and there are the following problems: it is long 1, to take the classroom instruction time, and 2, can't carry out comprehensive and accurate assessment, 3, assess and often can't carry out at any time to student's overall condition.

Summary of the invention

The utility model exists in order to solve existing Classroom Teaching assessment mode: take the classroom instruction time long, can't a kind of wireless classroom TQA device have been proposed to student's overall condition problem such as carry out that comprehensive and accurate assessment and assessment often can't be carried out at any time.

The utility model is to adopt following technical scheme to realize: wireless classroom TQA device, comprise launch terminal, the receiving terminal that is connected with computing machine, described launch terminal comprise single-chip microcomputer, on establish the control panel of some selection keys that link to each other with the single-chip microcomputer signal input part and the wireless telecommunications transmitter module that links to each other with the single-chip microcomputer signal output part; Receiving terminal comprises the interface circuit that single-chip microcomputer, the wireless telecommunications receiver module that links to each other with the single-chip microcomputer signal input part, being used for of linking to each other with the single-chip microcomputer signal output part are connected with computing machine.

Selection key can be a letter: A, B, C, D, numeral: 1,2,3,4, Chinese character: fully understanding, basic comprehension, do not understand fully, satisfied, general, dissatisfied or the like.

During use, be connected with computing machine by the interface circuit of data line receiving terminal, the teacher asks a question by the mode of projecting apparatus screen or oral enquirement, launch terminal of student's staff, according to the actual conditions of oneself, press the selector button on the launch terminal control panel, the single-chip microcomputer of launch terminal will characterize the data of student's selection and be launched by the wireless telecommunications transmitter module, the wireless telecommunications receiver module of receiving terminal receives immediately, and transfer to single-chip microcomputer, transfer to computing machine by interface circuit through data line then, computing machine is under the support of related software, the signal that is sent by each launch terminal that receiving terminal is received is added up, analyze, be converted into and characterize the form that the student selects situation, histogram, video datas such as cake chart are controlled projector at last with form, histogram, video datas such as cake chart are shown on projecting apparatus screen; The teacher can fully understand the quality of instruction of its this time by data status, for example: whether teacher's examination question that oral inquiry is said is understood, A is for understanding fully, B is a basic comprehension, C is not for understanding fully, and the student selects by launch terminal, as the result for A reaches 80%, B reaches 15%, C reaches 5%, illustrates that then this explanation to this examination question of teacher is extremely successful; As C to occupy proportion bigger, illustrate that then Most students do not understand, the teacher tackles this examination question and explains once more.

Compare with existing classroom selective examination conventional teaching evaluation measures such as put question to, fill in questionnaires, the utility model adopts the digitalized electron communication facilities to constitute, can be when evaluation problem proposes, promptly student's selection result is carried out statistical treatment, and showing instantly, realized classroom instruction easily and fast, in time, purpose of appraisals accurately; Next owing to use communication, need not laying-out, does not also need special classroom, can use in the classroom that computing machine and projector arranged arbitrarily at any time, and the expansion that helps classroom teaching evaluation is with universal; Moreover, because the classroom statistics has directly adopted digitized storage means, greatly simplified the statistical study of classroom data, being convenient to the teacher understands the improved macroscopic view of long-term quality of instruction, help existing the emphasis problem to search in the teaching, and the interchange of the empirical data between the teacher, help the accumulation of experience with students and the assurance of teaching difficulty, form long-term experience with students resource.

The utility model is rational in infrastructure, simple, and is easy to use, and result of use is obvious, greatly saved the evaluation time, is easy to use popularize, and is with a wide range of applications.
