Embodiment
The invention discloses a kind of university student's capability of independent innovation teaching method based on TRIZ.。Below for Michelson interferometer, illustrate and how to set up its teaching method.
. seek original innovation rule and cultivate Original Innovative Capability
The drop-anchor model learning of constructivist learning theory, be the special cognitive and technology group of warm Bill, under the leader of John Bu Langsi Ford, the teaching pattern based on technology of exploitation, so-called " anchor " is exactly the situation of poly-talented problem.Drop-anchor model learning requires to be based upon on the basis of infectious real event.We use drop-anchor model learning, present the real event that the content of courses produces from source, the actual application ability of strengthening student, and guiding student to study science the rule found from historical point view, uses TRIZ training student to explore the Original Innovative Capability of nature rule.For Michelson interferometer, cultivate Original Innovative Capability and undertaken by following five links.
set up situation
Set up situation makes the study of student carry out when reality is basically identical.Therefore, with video and audio material, PPT courseware, site resource and experimental apparatus composition three-dimensional teaching environment, allow Back In Time to source---real event when Michelson interferometer produces.1880, Jia Min interferometer, in the H.V. Helmholtz laboratory of Humboldt, when detecting the earth in " ether " middle motion, was modified into Michelson interferometer by American Physical scholar Mechelson, A. A..We analyze Jia Min (Jiman) interferometer by experiment, as shown in Figure 1, the interference fringe lightness of Jia Min (Jiman) interferometer is higher, but the interval that two relevant light beam A and B divide out is relevant with parallel glass plate thickness, this interval is usually smaller, limit some experiments, therefore the adaptability of instrument system is poor.According to 2008TRIZ contradiction matrix table, " adaptability " of instrument system should be improved, but weaken " lightness " of (deterioration) interference fringe.The engineering parameter sequence number of " adaptability " and " lightness " is respectively 32 and 23, in matrix table, the numeral of the 32nd row and the matrix element corresponding to 23 row infalls is the inventive principle sequence number of recommending, namely 1,32,35,24,17,19,28,26, according to TRIZ recommend 8 inventive principle as tech economic analysis, use first three inventive principle that Jia Min interferometer is evolved into Michelson interferometer
Table 1 2008TRIZ contradiction matrix table
Split according to the inventive principle 1 that TRIZ recommends: by object segmentation independently part.In Fig. 1 two block glass is divided into six blocks of thinner glass, places in Fig. 22,3,4,5,6 and 7 respectively.
Inventive principle 32 changes color: the transparency changing an object.3 glass in Fig. 2 are changed into half silvered glass, is translucent half reflection glass.
Inventive principle 35 changes characteristic: change concentration or density.In fig. 2, change the concentration of 3 translucent glass compositions, more clear after making A line and B line interval separately; Change glass 5 and 7 fractions concentration, changed over catoptron, 3,4 and 6 remain clear glass.
Jia Min interferometer is evolved into Michelson interferometer by above three inventive principle, as shown in Figure 2.Mechelson, A. A. has been invented this interferometer and has been used it to carry out fundamental metrology research acquisition Nobel prize for physics in 1907, and he is first American obtaining this honor.
problem identificatioin
Under above-mentioned situation, the closely-related authenticity event of study theme is exactly " anchor ", and Michelson experiment is exactly " anchor ".Multimedia is used to present the real event of Michelson experiment at that time.
autonomous learning
Autonomous learning is not directly tell how student should go to solve problems faced by teacher, but is provided the relevant clue solving this problem to student by teacher.
study in coordination
Student copies above-mentioned experiment real situation, according to teacher for the relevant clue solving this problem, uses Michelson interferometer, the actual application ability of strengthening student.According to equation, wavelength X=2 Δ d/ Δ k mobile mirror changes the optical path difference Δ d of two catoptrons to half silvered glass, often " emerge " or " indentation " Δ k=50 striped note single reading, survey 250 rings altogether, the mean value of Δ d is obtained with graded subtract, obtain wavelength X and compare with standard wavelength, calculating percentage error.After student's hands-on, the discussion of different viewpoints, interchange, supplement, revise, deepen the heightened awareness of each student to Michelson interferometer.
effect assessment

The route only finding instrument to evolve from source, seeks the rule of original innovation, cultivates undergraduate Original Innovative Capability, could produce a collection of original innovation leading in the world in the near future.
. seek integrated innovation rule and cultivate integrated innovation ability
The Scaffolding Teaching of constructivist learning theory, " the most contiguous development zone " that derive from the famous psychologist's Vygotsky of USSR (Union of Soviet Socialist Republics) is theoretical, uses " framing scaffold " that use in building trade and likens as the imagery of conceptual framework.This framework is set up according to " the most contiguous development zone " of students intelligence, thus by the supporting role of this " framing scaffold ", the intelligence of student is risen to another new level from a level.In university's core curriculum content, have many contents to be the basis of current numerous technical development, therefore university's core curriculum content and current numerous technology can form an organic whole.Technology evolution theory in TRIZ is by the analysis to world patent storehouse, find and confirm evolution of technology model and evolution line has transferability, this theory can not only the development of forecasting techniques, and can also predict the possible configuration state of product, has directive function for design innovative.We use Scaffolding Teaching, around the current science and technology of content of courses contact, present the sight of new technology and new instrument generation, use the integrated innovation ability of the theoretical training student of TRIZ.Cultivate integrated innovation ability to be undertaken by following five links.
scaffold erecting
Around study theme, conceptual framework is set up by the requirement of " the most contiguous development zone ", therefore, with video and audio material, PPT courseware, site resource and experimental apparatus composition three-dimensional teaching environment, Michelson interferometer is evolved into the real event of ground gravitational wave measurement mechanism by residue five inventive principle presenting TRIZ recommendation.
Inventive principle 24, intermediary according to TRIZ recommends: use central object to transmit or perform an action.Gravitational wave can perform an action as central object.Gravitational wave can produce the photon stream with the disturbance of laser same frequency perpendicular to the direction of propagation of laser, and interference fringe is moved.
Inventive principle 17, be converted to new dimension: ray cast to contiguous region.Because gravitational wave is too weak, ray cast to contiguous region, increase light path, the effective length of interference arm is increased, could measuring accuracy be improved, so the gravitational wave brachium of U.S.'s construction is the longest reach 4000 meters.As shown in Figure 3, according to inventive principle 17, we adopt two kinds of methods to increase light path: (1) increases the distance L between 4 and 5
1, increase the distance L between 6 and 7
2; (2) by Fig. 24 and 6 clear glass change in Fig. 34 and 6 phase regulator, change 2 clear glasses into circulation mirror, make laser multiple reflections between 4 and 5, make laser multiple reflections between 6 and 7.
Inventive principle 19, periodically action: if effect has been the cycle, then change its frequency.When gravitational wave comes then, act on the laser of ground gravitational wave measurement mechanism light arm, change the frequency of laser, interference fringe is moved.
Inventive principle 28, replace mechanical system: use up, sound, heat, olfactory system replace mechanical system.When gravitational wave arrives, change the frequency of laser, interference fringe is moved, the light intensity change caused by photodiode detection moving interference fringes, judges the existence of gravitational wave.
Inventive principle 26, to copy: replace object (or object system) with optical imagery, then reduce or amplify it.Changed by the light intensity of 8 photodiodes, utilize 9 difference engines and 10 correlators to copy relation between light intensity and phase place, obtain the change of phase place, obtain the value of gravitational wave to be measured.
enter situation
Student enters among the situation of the real event of new technology and new instrument generation, is equivalent to student and starts to climb " framing scaffold ".Inventive principle is the node in conceptual framework, and conceptual framework is the basis realizing Scaffolding Teaching, and it is the teaching " framing scaffold " helping students intelligence upwards to develop.
exploration
Explore when starting and want first to inspire guiding by teacher, help can be more; Then allow student oneself go to analyze, in heuristic process, teacher will point out in good time, helps student progressively to rise along conceptual framework; Reduce prompting gradually later; Finally will strive for accomplishing without the need to teacher user, student oneself can continue soaring in conceptual framework.
study in coordination
Carry out panel discussion.The inner link of main discussion Michelson interferometer and ground gravitational wave measurement mechanism, the basis of shared collective thinking achievement reaches more comprehensive to content of the discussions, correct understanding, namely finally completes the meaning Construction to knowledge.
effect assessment
Evaluate student is to the contribution done by Team Cooperation Learning; Whether evaluate student understands the inner link of Michelson interferometer and new technology and new instrument; Whether scientificity strengthens the actual application ability of student; Whether guiding student seeks integrated innovation rule to scientificity; Whether scientificity focuses on the integrated innovation ability using innovative approach training student.
Use TRIZ Michelson interferometer to be evolved into ground gravitational wave measurement mechanism, as shown in Figure 3, to seek integrated innovation rule, cultivate undergraduate integrated innovation ability.Current evolution of technology is not random, follows certain objective law and pattern yet, and the creation of all technology and upgrading are all to the most powerful function development.In International Technology competition, various correlation technique is organically blended, the entirety realizing key area breaks through, and is the important symbol improving national overall national strength.
seek rule of assimilating advanced foreign technologies and further refine them and cultivate ability of assimilating advanced foreign technologies and further refine them
The random entry type teaching of constructivist learning theory is that student enters the study of complex contents by different modes, thus obtains the many-sided exploration to same problem.We use random entry type to impart knowledge to students, sciences problems is entered from the research mode of ground gravitational wave measurement mechanism---gravitational wave detection, present the sight of scientist's search problem and using method, use the ability of assimilating advanced foreign technologies and further refine them of the theoretical training student of TRIZ.Cultivation ability of assimilating advanced foreign technologies and further refine them is undertaken by following five links.
present basic situation
With video and audio material, PPT courseware, site resource and experimental apparatus composition three-dimensional teaching environment, present the real event of gravitational wave detection.Present the real event that ground gravitational wave is evolved into space gravitational wave, and to sciences problems---detect gravitational waves and predict.Human research's gravitational wave ISUZU company, does not also have direct detection so far to gravitational wave.In relativity, gravitational wave can be calculated and pass to solar strain and be about h=3 × 10
-21, the sensitivity of current ground laser interference gravitational wave has reached precision so.The short pulse occurred in Virgo supergalaxy group scope or High Frequency Gravitational Waves number of times less, be the main cause that gravitational wave is not yet detected on ground.1989, US and European scientist planning moved to space gravitational wave detection experiment from ground, ites is desirable to detect medium and low frequency gravitational wave.Space gravitational wave detection plan LISA(Laser Interferometer Space Antenna) be the collaborative project of NASA (NASA) and European Space Agency (ESA).LISA launches 3 space probes in the year two thousand twenty later, and forming a length of side is 5 × 10
6the area of the equilateral triangle of km, carries out laser interference range finding between them mutually, to detect gravitational waves.High Frequency Gravitational Waves (10 Hz-10 kHz) is the most responsive frequency band of ground gravitational wave measurement mechanism.We analyze ground gravitational wave measurement mechanism, as shown in Figure 3, find that this instrument system detects the adaptability of medium and low frequency gravitational wave poor, according to 2008TRIZ contradiction matrix table, improve (improvement) this device to " measuring accuracy " of medium and low frequency gravitational wave, " area of moving object " of (deterioration) this device must be increased simultaneously.The engineering parameter sequence number of " measuring accuracy " and " area of moving object " is respectively 48 and 5, in 2008 contradiction matrix tables, the numeral 10,24,28,3,5,26 and 35 of the 48th row and the matrix element corresponding to 5 row infalls is the inventive principle sequence number of recommending.According to TRIZ recommend 7 inventive principle as tech economic analysis, ground gravitational wave measurement mechanism can be evolved into a kind of space laser interfere gravitational wave.
Table 2 2008 contradiction matrix table
Inventive principle 10, pre-operation is recommended: in advance special arrangement is carried out to object, make it have preparation in time, or be in easy-operating position according to TRIZ.Need to carry out special arrangement to whole measuring system in advance, if " area of moving object " that make this device worsen is saved most, as shown in Figure 4, should launch and organize into groups by being positioned at the gravitational wave detection that three, equilateral triangle top spacecraft forms, it is 10 that 3 detectors form a length of side
3-10
9the equilateral triangle constellation of km, namely the angle between every two spacecrafts is 60 °, and the center of constellation runs on Earth's orbit, and falls behind the earth 20 °, constellation plane becomes 60 ° of angles with ecliptic plane, this design is the impact caused to reduce terrestrial gravitation as far as possible.There is preparation in time, when 3 detectors arrive the gravitational wave detection experiment track around day, be in easy-operating position, then use laser interference method direct detection gravitational wave.
Inventive principle 24, intermediary: use central object to transmit or perform an action.Detected by the intermediary of gravitational wave as space gravitational wave, gravitational wave can perform an action and make moving interference fringes.The gravitational wave wave source existed in universe mainly contains two classes: the random gravitational wave of the gravitational wave that isolated celestial body produces and background.Low-frequency band gravitational wave signal is the most responsive frequency band of this device.
Inventive principle 28, replace mechanical system: use up, sound, heat, olfactory system replace mechanical system.The light beam sent at the laser instrument of space probe is interfered through producing at the catoptron roundtrip of space probe, when gravitational wave arrives, can measure the movement of interference fringe with photodiode.Each spacecraft has two identical optical tablees, includes the optical device of the composition interferometers such as LASER Light Source, optical beam-splitter, photodetector, optical frames group, and a series of electron device carrying out digital signal processing.Because the angle between every two spacecrafts is 60 °, each each optical table spaceborne can interfere with adjacent spaceborne optical table, and the distance that laser covers this section of spacecraft interval needs a period of time.Below be mounted with an alloy cube as " test mass " (75% gold medal and 25% platinum) at each interferometer, one of them surface is polished into smooth level crossing and is used for reflects laser.If there is the inswept test mass of gravitational wave, the minor alteration of its position can cause interference signal, i.e. the change of laser phase, can derive the existence of the gravitational wave observed from this phase place change.
Inventive principle 3, local quality: the different piece of object realizes different functions.Gravitational wave, as a part of material in cosmic space, has the function that other moieties are different.Gravitational wave has extraordinary coherence, utilizes its coherence can improve the detectivity of gravitational wave.In actual design, this measuring accuracy requires that the environment high residing for test mass is stablized, and its position can not be subject to the impact of extraneous optical pressure and solar wind particle; And the interferometer measuration system of this device also wants High sensitivity, the real gravitational wave signal needed is made to be unlikely to be submerged in the ocean of the interference such as laser frequency noise.In addition, how this device tackles the impact of spacecraft operation on the Doppler effect that laser frequency causes if also needing to solve, the loss of laser long-distance transmission is asked.
Inventive principle 5, merging: spatially similar object is linked together, make it complete parallel operation.Spatially, medium and low frequency gravitational wave has similar coherence with the laser of this device, and gravitational wave can produce the photon stream with the disturbance of laser same frequency perpendicular to the direction of propagation of laser, makes it complete parallel operation, i.e. moving interference fringes.The length that the distance of this device in actual motion between each spacecraft reaches more than millions of km can detect moving interference fringes 10 micromicron, and (1 micromicron equals 10
-12rice) more than length variations.
Inventive principle 26, to copy: can be studied complication system by virtual reality technology.Because the interaction of gravitational wave and other materials is very weak, the gravitational wave therefore produced in early universe carries the information of early universe.The gravitational wave that this device detects, can copy the situation of gravitational wave source by virtual reality technology, if " the original gravitational wave " that produce when detecting Big Bang, and situation when can copy Big Bang by virtual reality technology.The fundamental purpose of spatial attraction ripple detection is the dynamic effect that detects gravitational waves, and this is not only Direct Test einstein general relativity, provides the positive evidence that gravitational wave exists, and its larger order is the understanding structure in universe and the new secret of evolutionary process.
Inventive principle 35, Parameters variation: the physical state changing system.The change of celestial body in solar system parameter, can change the state of laser in this apparatus system, so this device should be able to measure the change of celestial body in solar system parameter, such as, surveys and draws the distribution of solar system gravitation.
Above according to 7 inventive principle that TRIZ recommends, ground gravitational wave measurement mechanism is evolved into a kind of space laser and interferes gravitational wave, and predict the result that this device detects gravitational waves.As shown in Figure 4,1. spacecraft 1; 2. spacecraft 2; 3. spacecraft 3; 4. the earth; 5. the sun.The structure of this device and principle of work: forming a length of side by 3 detectors is 10
3-10
9the equilateral triangle constellation of km, namely the angle between every two spacecrafts is 60 °, and the center of constellation runs on Earth's orbit, and falls behind the earth 20 °, constellation plane becomes 60 ° of angles with ecliptic plane, this design is the impact caused to reduce terrestrial gravitation as far as possible.Each spacecraft has two identical optical tablees, includes the optical device of the composition interferometers such as LASER Light Source, optical beam-splitter, photodetector, optical frames group, and a series of electron device carrying out digital signal processing.Because the angle between every two spacecrafts is 60 °, each each optical table spaceborne can interfere with adjacent spaceborne optical table, and the distance that laser covers this section of spacecraft interval needs a period of time.Below be mounted with an alloy cube as " test mass " (75% gold medal and 25% platinum) at each interferometer, one of them surface is polished into smooth level crossing and is used for reflects laser.If there is the inswept test mass of gravitational wave, the minor alteration of its position can cause interference signal, i.e. the change of laser phase, can derive the existence of the gravitational wave observed from this phase place change.
