Nrog kev txhim kho kev kawm txuas ntxiv ntawm kev kawm thiab kev nce qib hauv cov tub ntxhais kawm ua haujlwm hauv chav kawm ntawv Hauv ib puag ncig niaj hnub no .
1. Visual kev nplij siab thiab kev pom tseeb
Greenboards muaj kev pom zoo dua pom kev piv rau cov xim ntsuab ntxiv rau thaum lub greenboard zoo dua thiab nyeem tau zoo dua li ntawm lub teeb ci ntsa iab thiab nyeem tau zoo dua li qhov kaj nrig ntxiv.} los yog xim chalk rau ntawm cov keeb kwm yav dhau los tsim cov ntaub ntawv sib txawv, ua rau cov ntawv sau kom meej thiab yooj yim rau cov tub ntxhais kawm nyeem {{4}
{{0 {}} txo cov teeb meem hmoov av
Thaum siv Blackboard, tso ib txwm chalk ua rau muaj kev noj qab haus huv thiab cov tub ntxhais kawm, uas tsis muaj plua plav, uas tsis muaj kev noj qab haus huv Kev Cuam Tshuam .

{{0 {}} versatility thiab sib cuam tshuam
Cov khoom muag niaj hnub no feem ntau tau nruab nrog cov nta ntse, kev sib txuas lus hauv chav kawm muaj kev sib txuas lus, ua rau cov neeg kawm ntawv sib txuam, ua haujlwm ntxiv, kev koom tes. Tsis tas li ntawd, qee cov ntsuab tso cai tso cai rau kev sau ntawv, kos duab, thiab txuag cov ntaub ntawv, ua kom qhia tau yooj yim thiab muaj txiaj ntsig.
5. yooj yim tu thiab txij nkawm
Cov ntawv ntsuab feem ntau yog ua rau cov ntaub ntawv tshwj xeeb uas yuav tsum tau ntxuav cov kab ke ua kom tsis muaj cov kab ke, tsis muaj kev sib txuas lus rau cov cim ib txwm muaj thiab cov khoom siv tsis zoo li, cov khoom siv tsis zoo li no, Blackboards, cov zaub ntsuab tau yooj yim dua los tswj thiab xav tau kev siv zog tsawg.
{{06. Txo cov suab nrov
