Nyob rau hauv kev kawm, chaw ua haujlwm, thiab cov chaw sib ntsib, diam av, greenboards, thiab cov ntawv luam tawm yog cov cuab yeej sau ntawv tshaj plaws. Txhua tus muaj nws tus kheej zoo thiab qhov tsis zoo, ua rau lawv haum rau cov xwm txheej sib txawv. Kab lus no muab cov ncauj lus kom ntxaws tshuaj xyuas ntawm lawv qhov sib txawv los pab cov nyeem xaiv cov cuab yeej sau tsim nyog tshaj plaws.
1. Cov ntaub ntawv thiab cov cuab yeej sau ntawv
Daim kas dan: Cov duab dub yog feem ntau ua los ntawm cov ntoo lossis cov hlau nplaum nrog cov nplaim hluav taws xob nrog cov xim xim dub. Chalk yog siv rau kev sau ntawv. Qee cov ntaub ntawv niaj hnub siv cov ntaub ntawv sib nqus, tso cov hlau nplaum yuav tsum tau txuas nrog rau kev qhia zoo dua thiab cov hom phiaj qhia.
Daim duab ntsuab: Zoo ib yam li Blackboards, Greenboards feem ntau yog ua los ntawm cov fiberboard fiberboard lossis iav nrog ntsuab txheej. Chalk yog siv rau kev sau ntawv. Cov khoom ntsuab muaj pab txo lub teeb pom kev zoo, txo qhov muag pom.
Tus khaub ncaws dawb: Cov ntawv luam yeeb no feem ntau yog ua los ntawm txha hniav laus, iav, lossis cov tsiaj ua ke. Lawv xav tau cov cim tshuab luam yeeb rau kev sau ntawv, uas tuaj yeem yooj yim tshem tawm thiab rov siv dua. Sib nqus cov lus pub dawb pub rau cov ntawv txuas nrog cov ntaub ntawv thiab cov cim, ua rau lawv zoo tshaj rau chaw ua haujlwm thiab qhia chaw.
2. Sau cov kev paub thiab pom pom
Daim kas dan: Daim ntawv sau cov chalk yog qhov tseeb, tab sis nws ua cov hmoov av thiab hnav thaum lub sijhawm. Cov khoom noj tsis tshua muaj cov xim av yuav tsim cov khawb thiab qhov chaw tsis ncaj, cuam tshuam rau kev sau ntawv zoo.
Daim duab ntsuab: Piv rau Blackboards, Greenboards txo cov Chalk Plha voos thiab muab lub ntsej muag sib piv nrog, ua rau lawv yooj yim rau lub qhov muag kom pom kev. Ntau lub tsev kawm ntawv hloov cov blollboards nrog cov zaub ntsuab los txhim kho chav kawm ib puag ncig.
Tus khaub ncaws dawb: Sau nrog cov cim tshuab ntxhua khaub ncaws dawb yog tus ua kom du, thiab cov ntawv nyeem yog qhov tseeb nrog cov xim tshee. Nws tuaj yeem tshem tawm yooj yim nrog lwv cov kab xev, tshem tawm plua plav. Txawm li cas los xij, lub teeb ci ntsa muaj zog yuav ua rau pom kev, ua tiav nyeem ntawv nyuaj. Ib qho ntxiv, cov neeg cov neeg saib dej qis qis yuav tawm ntawm cov cim dab neeg, uas pom cov hnoos qeev txawm tias tom qab lwv.
3. Txij Nkawm thiab Kev Tu
Blackboard / Greenboard: Cov ntawv sau ua paug yuav tsum muaj pob txha caj npab lwv, tab sis hmoov av tuaj yeem tseem ua tau ntxiv, txo qis huv. CHALLALT CARDS tseem ceeb nrog siv, ua rau lawv yooj yim dua rau kev sau ntawv ntev thiab yuav tsum hloov cov kev hloov nquag.
Tus khaub ncaws dawb: Cov kab mob watcheboard cov kua mis tuaj yeem tshem tau yooj yim, tab sis yog tias tsis raug cai ntev, cov cim yuav dhau mus, xav tau kev tshem tawm kom sov lossis dej caw kom tshem tawm. Sij hawm dhau mus, cov ntug dej sov tuaj yeem ua rau, ua rau nws nyuaj rau kom huv si.
4. Cov ntaub ntawv tsim nyog
Blackboard / Greenboard: Vim tias tus nqi qis ntawm chalk thiab nws cov durability, blackboards thiab greenboards tseem dav siv hauv cov tsev kawm ntawv, tshwj xeeb yog cov chav kawm ib txwm muaj thiab chav qhia. Cov kws ua yeeb yam thiab cov neeg tsim qauv kuj siv cov duab dub rau cov duab kos thiab muaj tswv yim ua haujlwm.
Tus khaub ncaws dawb: Cov ntawv luam dawb yog nrov rau hauv chav ua haujlwm, cov chav sib tham, thiab chav kawm niaj hnub vim lawv tau kev tu thiab sau kom huv. Lawv yog cov tseem ceeb tshwj xeeb rau kev nthuav qhia thiab kev sib tham sib tham. Nyob rau hauv cov rooj sib tham txog tej thaj chaw deb thiab kev kawm online, digital cov neeg dawb huv (xws li ntse rasboards tshiab) tau ua nrov dua.
5. Ib puag ncig thiab kev noj qab haus huv
Blackboard / Greenboard: Cov ntawv sau cov hnoos qeev kom ua rau muaj plua plav, uas yuav cuam tshuam kev noj qab haus huv thiab ua rau tawv nqaij khaus, tshwj xeeb yog rau cov tsis haum rau chalk. Qee lub tsev haujlwm tau qhia txog plua plees-dawb chalk kom txo qis kev phom sij.
Tus khaub ncaws dawb: Cov ntawv luam cov duab paj nruag feem ntau yog ib txwm muaj ib txwm muaj nyob ib puag ncig lawv tsis tsim hmoov av. Txawm li cas los xij, cov cim qis qis yuav muaj cov tshuaj tsis muaj kuab lom, xav tau qhov muaj qhov ntsuas tau kom tsim nyog thaum siv. Cov neeg uas nquag siv cov neeg ntxhua khaub ncaws dawb yuav tsum xaiv rau cov ntxhiab tsw tsawg lossis tsis muaj tshuaj lom rau kev noj qab haus huv zoo dua.
6. Nqi thiab durability
Blackboard / Greenboard: BlackBoards thiab greenboards muaj tus nqi qis dua, thiab chalk yog pheej yig. Txawm li cas los xij, chalk yog noj sai sai, ua rau cov nqi ntev dua. Tsis tas li ntawd, Blackboard thiab Greenboard chaw hnav tawm sijhawm, uas xav tau kev hloov sijhawm ua ntu zus lossis kho kom zoo.
Tus khaub ncaws dawb: Cov ntaub ntawv dawb paug muaj cov nqi siab dua tab sis muaj nyiaj ntev dua. Cov cim zais cia yog kim dua chalk tab sis ntev dua. High-end iav wewboards lossis ntse weepards, txawm tias muaj nuj nqis, muab ncua ntev thiab zoo rau kev nqis peev ntev.
7. Yav Tom Ntej Tiam
Nrog kev txhim kho thev naus laus zis, cov duab dub thiab cov ntaub ntawv dawb yog hloov kho kom ua cov kev daws teeb meem ntse. Piv txwv li, ntse cov ntxaij vab tshaus tau sib txuas, kev sau ntawv digital, thiab chaw taws teeb sib qhia, txhim kho ib puag ncig kev qhia thiab chaw haujlwm. Tsis tas li ntawd, kev siv cov khoom siv eco, xws li plua plav dawb paug av dawb, yog tsav tsheb tshiab hauv Blackboards, cov ntawv tshiab, thiab cov ntawv thov.
Tag
Blackboards, cov greenboards, thiab cov ntawv theej peb muaj lawv tus kheej thiab haum rau cov xwm txheej sib txawv. Blackboards thiab Greenboard tseem siv dav hauv cov tsev kawm ntawv thiab kev qhia ua haujlwm tau zoo thiab cov neeg xa khoom noj kom zoo nkauj thiab kev sib ntsib rau lawv cov hmoov av-huv thiab huv. Nrog kev nce qib thev naus laus zis thiab nce ib puag ncig kev paub, cov cuab yeej siv tom ntej yuav dhau los ua neeg ntse dua thiab Eco-phooj ywg ntawm kev qhia thiab chaw ua haujlwm. Xaiv cov cuab yeej sau ntawv sab xis raws li kev xav tau tuaj yeem txhim kho kev ua tau zoo thiab cov neeg siv kev paub.
