The physiological reaction signal for surveying control that cannot autonomous of student during listening to the teacher, obtains the focus of student, and then according to every
The focus of a student obtains the evaluating result of teachers ' teaching, can not only know student during listening to the teacher in real time as a result,
Focus, and it is more consistent based on the quality of the determining student's focus of physiological reaction signal and teachers ' teaching.
Below with reference to the accompanying drawings the assessment method and system of the teachers ' teaching of the embodiment of the present invention are described.
Fig. 1 is the flow chart of the assessment method of the teachers ' teaching of one embodiment according to the present invention, as shown in Figure 1, should
Method includes:
Step 101, real-time physiological reaction signal of the student within the teachers' instruction period is obtained.
Wherein, physiological reaction signal, including skin conductance signal, heart rate signal, electrocardiosignal, eye movement signal, brain telecommunications
Number one or more of signal combination.Specifically, in an embodiment of the present invention, it can be acquired by skin sensor equipment
The physiological reaction signal of student, wherein according to the difference of application scenarios, skin sensor equipment can be different equipment, than
Such as, the student's skin that can be directly contacted for the wrist strap comprising skin sensor, cap, gloves, necklace, face's paster etc.
Equipment.
It should be understood that the application scenarios of physiological reaction signal of student during listening to the teacher are obtained in step 101, it can
To occur in actual teaching scene, under the scene, each student to listen to the teacher wears the equipment comprising skin sensor,
It can also occur in the teaching scene of the course on the lines such as remote teaching, under the scene, each student to listen to the teacher wears packet
Collected skin conductivity data are uploaded to system by the equipment comprising skin sensor by the equipment containing skin sensor.
It is emphasized that in practical applications, the teaching period of teacher is generally divided into knowledge point explanation, problem answer etc.
It gives lessons the period, and, including call the roll etc. and non-to give lessons the period, it is clear that teacher is in the quality of instruction for period of giving lessons and the teaching of teacher
It is closely bound up, thus, in an embodiment of the present invention, the assessment imparted knowledge to students for the period of giving lessons of teacher.
Under different application scenarios, determine that the mode of period of giving lessons includes but is not limited to, by teacher according to preparing lessons
Situation is preset, alternatively, analyze according to the voice messaging of giving lessons detected determining etc..
Step 102, real-time focus that student listens to the teacher is determined according to real-time physiological reaction signal.
Wherein, under different application scenarios, the focus of each student can be indicated with specific numerical value, such as with percentage
Digital representation in system, numerical value is bigger to represent that student is more absorbed, for example is indicated with the grade in hierarchy, the representative of bigger grade
Student is more absorbed, is for another example indicated with the quantity of specific symbol (star symbol, flower symbol, heart symbol etc.),
Symbol quantity, and to represent student more absorbed.
It is appreciated that the physiological reaction signal of student can really react the focus of student, when physiological reaction signal packet
When including skin conductance signal, certain resistance can be presented in skin to electric current or voltage, and the size of resistance can become with mood
Change and change, in general, in the state of more light, student may be currently absent-minded, and it not is very absorbed for listening to the teacher, human skin
Resistance it is larger, so that skin conductance signal is lower, when nervous or absorbed, what student may currently be absorbed in listens
The resistance of class, human skin is smaller, so that human skin conductance signal is higher, this is because sympathetic and parasympathetic nerve is according to big
The variation of the cognitive state of brain carries out the adjusting of antagonism formula, and sympathetic and parasympathetic activity will affect skin resistance.
For another example, when physiological reaction signal includes heart rate signal, if the heart rate volatility of student is smaller, show student
It is absorbed in the current content of courses, if the changes in heart rate of student is bigger, shows not special to the current content of courses
Note.
It should be noted that under different application scenarios, can be used different modes realize it is anti-according to the physiology of student
Induction signal determines the focus of each student, illustrates as follows:
The first example:
In this example, previously according to lot of experimental data, obtain and store the correspondence of focus and physiological reaction signal
Relationship, thus, after obtaining physiological reaction signal, above-mentioned corresponding relationship is inquired, to obtain the focus of matched student.
Second of example:
Previously according to lot of experimental data, the deep layer network model of physiological reaction signal is constructed, the input of the model is made a living
Reaction signal is managed, the focus for student is exported, thus, the physiological reaction signal for the student that will acquire inputs the deep layer network mould
Type, the focus of the student exported.
The third example:
In this example, as shown in Fig. 2, above-mentioned steps 102 include:
Step 201, student is analyzed in the real-time physiological reaction signal given lessons in the period according to preset strategy, and extracted
The absorbed characteristic information of student.
It should be understood that under different application scenarios, the preset strategy of the physiological reaction signal of above-mentioned analysis student
Difference, so that the absorbed characteristic information of the student extracted is different:
As a kind of possible implementation, being absorbed in characteristic information is to be absorbed in number, then can detecte physiological reaction signal
Absorbed number is extracted greater than the number of preset threshold.
When physiological reaction signal is skin conductance signal, since in practical applications, student is more absorbed to current teaching,
Then the brain neurological motion of student is abundanter, and the stimulation and sympathetic nerve activity by the content of courses are influenced, and can make skin
The electrical conductivity on surface changes (its origin cause of formation is related with sympathetic nerve and sweat gland activity degree), and the state of mind is more absorbed, and skin conductivity is got over
Greatly, the skin conductance signal known according to this principle to detection is bigger.
For example, when physiological reaction signal is eye movement signal, since in practical applications, student is in current teaching
Rong Yue is absorbed in, then the eyes learned can be moved with teacher, so that the eye movement change rate signal detected is higher, student
The current content of courses is not absorbed in, then the eyes of student will not or sight mobile with teacher be not concentrated at screen or
On blackboard, so that the eye movement change rate signal detected is lower or blinkpunkt exceeds other than screen or blackboard.
Thus, in this example, previously according to the corresponding preset threshold of lot of experimental data setting skin conductance signal, mention
The number for taking skin conductance signal to be greater than preset threshold extracts absorbed number.
As alternatively possible implementation, the time that can detecte physiological reaction signal greater than preset threshold is extracted specially
Infuse the time.
When physiological reaction signal is skin conductance signal, since in practical applications, student is more absorbed to current teaching,
Then the brain neurological motion of student is abundanter, and the stimulation and sympathetic nerve activity by the content of courses are influenced, and can make skin
The electrical conductivity on surface changes (its origin cause of formation is related with sympathetic nerve and sweat gland activity degree), and the state of mind is more absorbed, and skin conductivity is got over
Greatly, the skin conductance signal known according to this principle to detection is bigger.
Thus, in this example, skin conductance signal can also be detected and extracted greater than the time of preset threshold and be absorbed in the time.
As another possible implementation, the amplitude that can detecte physiological reaction signal greater than preset threshold is extracted specially
Infuse intensity.
When physiological reaction signal is skin conductance signal, since in practical applications, student is more absorbed to current teaching,
Then the brain neurological motion of student is abundanter, and the stimulation and sympathetic nerve activity by the content of courses are influenced, and can make skin
The electrical conductivity on surface changes (its origin cause of formation is related with sympathetic nerve and sweat gland activity degree), and the state of mind is more absorbed, and skin conductivity is got over
Greatly, the skin conductance signal known according to this principle to detection is bigger.
Thus, in this example, skin conductance signal can also be detected and extracted greater than the amplitude of preset threshold and be absorbed in intensity,
If preset threshold is A, current skin conductance signal is the B greater than A, then can be using B-A as absorbed intensity.
Wherein, under different application scenarios, the absorbed characteristic information of the student of above-mentioned three kinds of examples acquisition be can be used as
Individual reference factor can also be by the special of the student of above-mentioned three kinds of examples acquisition for further determining that the focus of student
Any two kinds of combination of characteristic information is infused as reference factor, it, can also will be upper for further determining that the focus of student
The absorbed characteristic information of the student of three kinds of examples acquisition is stated as reference factor, for further determining that the focus of student.
In addition, the accuracy of the focus in order to guarantee to further determine that student, in one embodiment of the invention, on
Stating the preset threshold being compared with physiological reaction signal can also be arranged according to the somatotypes of student, for example work as physiological reaction
When signal is skin conductance signal, for the student of Female student and male student or different age group, skin table
The cutin in face and aridity etc. are different, thus, the skin conductance signal measured under same focus is difference, in order to
The difference on this physique constitution of students is compensated, this difference data can also be obtained according to lot of experimental data, for different constitutions
Different preset thresholds is arranged in student, for example, electric conductivity is stronger since male's sweat gland is generally more flourishing than women, thus sets
The preset threshold set is relatively higher etc..
Certainly, it under this application scenarios, needs in advance to obtain the somatotypes of student, acquisition modes can also be with
It is different according to the difference of application scenarios, for example, can be obtained what current participation teaching was paid attention to the class by means of the camera in classroom
The image information of student identifies the pupilage of corresponding position according to image information, thus by the essential attribute and speciality of student
It is associated with the skin sensor of corresponding position, it can be carried out according to the somatotypes of different students using different preset thresholds
It is absorbed in the acquisition of characteristic information.
Step 202, calculated using absorbed characteristic information of the preset algorithm to student, determine that student listens to the teacher it is real-time specially
Note degree.
Specifically, being counted according to the difference of application scenarios using absorbed characteristic information of the preset algorithm to each student
The mode for calculating the focus for obtaining each student is different, illustrates below with reference to different application scenarios:
Scene one:
Under the scene, the absorbed characteristic information of student is single characteristic information, for example is only absorbed number, or
Person is absorbed in the time, alternatively, being absorbed in intensity.
Since the corresponding data value of absorbed characteristic information of student is bigger, for example absorbed number is bigger, indicates that student is more special
It infuses in current teaching, therefore, the preset algorithm under this scene is linear operation algorithm corresponding with absorbed characteristic information, for example,
The algorithm can be Y=a*X, wherein Y is the focus of student, and X is to be absorbed in the corresponding data value of characteristic information, and a can be to appoint
Meaning is greater than 0 number.
Wherein it is possible to consider to be absorbed in difference when characteristic information includes different contents with the correlation of student's focus,
For example, the absorbed time of usual student is bigger compared to the reference significance of absorbed number in the focus for determining student, because
Sometimes, although student is repeatedly absorbed in current course, the duration is shorter, is believed that student is not absorbed in and works as
Preceding teaching, therefore, above-mentioned a are also can correspond to the weighted value of different absorbed characteristic informations, for example, being when being absorbed in characteristic information
When being absorbed in number, corresponding a is 0.6, and when absorbed characteristic information is to be absorbed in the time, corresponding a is 0.8.
Scene two:
Under the scene, the absorbed characteristic information of student is multiple characteristic informations, such as when including absorbed number and is absorbed
Between, alternatively, time and absorbed intensity are absorbed in, alternatively, being absorbed in number, being absorbed in time and absorbed intensity etc..
Since the corresponding data value of absorbed characteristic information of student is bigger, for example absorbed number is bigger, indicates that student is more special
It infuses in current teaching, therefore, corresponding preset algorithm data value corresponding with the absorbed characteristic information of student is positively correlated, for example, Y
=a1*X1+ ...+an*Xn, wherein n is positive integer more than or equal to 2, and a1 to an is positive number, and a1 to an can be equal, can also be with
It is unequal, when a1 to an is unequal, it can be used to indicate that the absorbed characteristic information of different students to the different of focus
The weighted value of reference significance, X1 to Xn indicate the different corresponding data values of student characteristics information.
Certainly, in the actual operation process, the pre- imputation in the scene can also be any absorbed feature for embodying student
The positively related algorithm expression of the corresponding data value of information, it is numerous to list herein.
Step 103, interest scores are generated according to the real-time focus that student listens to the teacher, and obtains teacher's according to interest scores
Teaching evaluating result.
It is appreciated that the focus and quality of instruction of student are closely related, usual students' union focuses more on quality of instruction
Higher course is therefore, more accurate to the teaching evaluating result for obtaining teacher according to the focus of student.
Wherein, in practical implementation, evaluating result can be different according to the difference of application scenarios, for example, the survey
Commenting result can be the fraction representation of hundred-mark system, can also be indicated for social estate system etc., as a kind of possible implementation, working as
When preceding evaluating result corresponds to hundred-mark system scoring, focus of each student to every class can be counted using preset algorithm
It calculates, obtains the interest scores of each student corresponding with every class, focus is corresponding with interest scores to close for example, pre-establishing
System, thus, after obtaining student to the focus of every class, above-mentioned corresponding relationship is inquired, corresponding interest scores are got, into
And the teaching evaluating result of teacher is obtained according to the interest scores of each student corresponding with every class, for example, every class is corresponding
Each student interest scores be weighted and averaged obtain quality of instruction evaluating result etc..
In practical applications, after the real-time focus that student listens to the teacher, what can also be listened to the teacher according to student is real-time absorbed
Degree carries out additional tutor auxiliary platform work, to help student to understand correlated knowledge point.
Specifically, as shown in figure 3, after above-mentioned steps 103, this method comprises:
Step 301, judge whether real-time focus is greater than preset threshold.
Step 302, it if judgement knows that real-time focus is greater than preset threshold, records and stores in the giving lessons of corresponding period
Hold.
Wherein, preset threshold is marked according to many experiments, wherein when real-time focus is greater than preset threshold, then
Show that student concentration listens current lecture contents, it may be possible to which the current content of courses is important or student understands difficulty
Greatly, thus, preferably listen to the teacher experience to give student, when judgement knows that real-time focus is greater than preset threshold, record and deposit
The lecture contents of corresponding period are stored up, in order to which lecture contents of the student to the corresponding period are repeated playing to digest in corresponding teaching
Hold, alternatively, in order to which teacher is explained or said again majorization of solutions etc. when reviewing the lecture contents of corresponding period.
Certainly, in order to further increase the experience of listening to the teacher of student, in one embodiment of the invention, real-time focus is small
When preset threshold, also teacher can be reminded in real time, in order to which teacher carries out the adjustment of the content of courses in time.
Specifically, with continued reference to Fig. 3, after above-mentioned steps 301, this method comprises:
Step 303, if judgement knows real-time focus equal to less than preset threshold, preset control information is inquired, is obtained
Take control instruction corresponding with real-time focus.
Step 304, feedback device is controlled according to control instruction and issues prompt warning, so that teacher adjusts the content of courses.
Wherein, the feedback device in the embodiment of the present invention includes intelligent lamp, balloon, the buzzer that can carry out prompt warning
Deng.
According to the difference of application scenarios, feedback device is different, so that corresponding control instruction is different from feedback device, than
Such as, when feedback device is intelligent bulbs, then corresponding control instruction can be color change control instruction.
Specifically, the control information for feedback device is preset, which includes real-time focus and control
The corresponding relationship of instruction, thus, when getting real-time focus equal to less than preset threshold, inquiry control information, acquisition pair
The control instruction answered controls feedback device according to control instruction and issues prompt warning, so that teacher adjusts the content of courses.
In order to further clearly describe the embodiment of the embodiment of the present invention, below by taking feedback device is intelligent lamp as an example
It is illustrated, is described as follows:
For example, as shown in figure 4, in field research scene, the student paid attention to the class is student 1-4, when feedback device is
When intelligent lamp above student region, the color of the intelligent lamp can change, to student 1-4's within the teachers' instruction period
Physiological reaction signal is acquired, after the focus that each student is determined according to the physiological reaction signal of acquisition, according to each student
Real-time focus generate interest scores, according to interest scores obtain teacher teaching evaluating result.
Wherein, after getting the real-time focus of each student, if judgement knows real-time focus equal to less than default threshold
When value, then intelligent lamp is controlled according to control instruction corresponding with real-time focus and carry out color change prompting teacher, such as intelligently
