# Imodeli Yohlobo Lwegazi Ejabulisayo ye-ABO: Ukwenza Ulwazi Lwesayensi Yokuphila “Lufinyeleleke Kakhulu”
Muva nje, isethi yamamodeli okufundisa aveza ngokucacile izimfihlakalo zesistimu yohlobo lwegazi lwe-ABO isibe “inkanyezi encane” emkhakheni wemfundo yesayensi yokuphila, ngenxa yomklamo wayo oyingqayizivele kanye nenani layo elisebenzayo.
Imodeli yohlobo lwegazi ye-ABO iqukethe izilingisi zamangqamuzana abomvu, amamojula esakhiwo se-antigen, njll. “Amaseli egazi abomvu” abomvu ahlanganiswe nezikhonkwane zemibala ehlukene, ezihambisana nama-antigen athile ezinhlobo zegazi ze-A, B, AB, kanye ne-O; isakhiwo sendandatho eluhlaza okwesibhakabhaka kanye nochungechunge lwezinhlayiya siveza ngokunembile izinhlobo zama-molecule zama-antigen e-A kanye ne-B. Ngokuhlanganisa nokuhlakaza imodeli, abafundi bangaqonda ngokwemvelo umehluko kuma-antigen ohlobo lwegazi, indlela ama-antibodies e-serum asebenza ngayo, futhi baqonde kalula isimiso sokuphendula kwegazi – isibonelo, lapho amaseli egazi abomvu ohlobo lwe-B engena ku-serum yohlobo lwe-A, inhlanganisela ye-antigen-antibody ibangela “ukulingiswa kwe-agglutination”, “ngokushesha” “ibone ngeso lengqondo” ulwazi olungabonakali.
Ekilasini lesikole samabanga aphakathi, uthisha uyisebenzisa ukukhombisa ukuqanjwa kwezinhlobo zegazi kanye nokufaniswa kwegazi, okwenza kube lula ukuqonda imibono eyinkimbinkimbi. Emisebenzini yokwazisa isayensi yezokwelapha, umphakathi ungavula kalula izimfihlo zezinhlobo zegazi ngokuzakhela wona ngokwawo. Kusukela ekufundiseni i-biology kuya ekukhanyiselweni kwezokwelapha, lo modeli uhlukana nemodi yokushumayela yendabuko futhi usebenzisa ukuxhumana okunembile ukwenza ulwazi lwesayensi yokuphila "lufinyeleleke", ukufaka amandla amasha emfundweni yokwazisa isayensi futhi kube ibhuloho losizo lokufundisa elisezingeni eliphezulu elixhumanisa ithiyori kanye nokwenza.
