Data collection. Cov txheej txheem ntawm kev sau cov ntaub ntawv zoo feem ntau siv hauv kev tshawb fawb txog kev noj qab haus huv yog kev tshawb fawb, kev soj ntsuam, kev xam phaj ib nrab thiab cov pab pawg tsom xam[1, 14, 16, 17].
Cov txheej txheem zoo hauv kev tshawb fawb zoo yog dab tsi?
Cov qauv zoo rau txhua qhov kev tshawb fawb zoo yog kev ntseeg siab, hloov pauv tau, kev cia siab, thiab . confirmability. Tsis tas li ntawd, kev hloov pauv yog ib feem tseem ceeb ntawm kev ua kom pom tseeb thiab zoo ntawm kev tshawb fawb zoo.
Cov qauv twg peb tuaj yeem siv los xyuas kom meej tias cov ntaub ntawv zoo siv tau?
Cov no criteria yog: (1) kev ntseeg siab, (2) kev hloov pauv, (3) kev vam meej, thiab (4) kev lees paub. Cov kws sau ntawv no mus ntxiv los qhia cov haujlwm uas tus kws tshawb fawb yuav ua rau kom paub meej tias cov cov txheej txheem yuav muaj nyob hauv txoj kev kawm.
Cov ntaub ntawv zoo cuam tshuam nrog dab tsi?
Cov ntaub ntawv zoo txhais tau tias yogcov ntaub ntawv uas kwv yees thiab tus yam ntxwv. Cov ntaub ntawv zoo tuaj yeem soj ntsuam thiab kaw. Hom ntaub ntawv no tsis yog tus lej hauv qhov xwm txheej. Cov ntaub ntawv no yog sau los ntawm cov kev soj ntsuam, kev xam phaj ib-rau-ib, ua pab pawg tsom, thiab cov txheej txheem zoo sib xws.
Koj ntsuas cov ntaub ntawv zoo li cas?
Ib txoj hauv kev uas cov kws tshuaj ntsuam xyuas siv los txheeb xyuas cov ntaub ntawv zoo yog triangulation, uas suav nrog kev noj cov ntaub ntawv,nrhiav cov ntsiab lus, coding lawv, thiab tom qab ntawd sib piv lossis triangulating cov ntaub ntawv los ntawm cov ntaub ntawv sib txawv thiab cov txheej txheem sau cov ntaub ntawv sib txawv.
