Iqela lolawulo lenziwe ngabathathi-nxaxheba abangafumani unyango lwezilingo. Xa uqhuba uvavanyo, aba bantu bakhethwe ngokukhethiweyo ukuba babe kweli qela. Baye bafana ngokufanayo nabachaphazelekayo abakwiqela lokulinga okanye abantu abafumana unyango.
Nangona bengayifumana unyango, badlala indima ebalulekileyo kwinkqubo yophando.
Iingcali ziqhathanisa iqela lokulinga kwiqela elilawulayo ukuqinisekisa ukuba unyango lunomphumo. Ngokukhonza njengeqela elifanisa, abaphandi banako ukuhlukanisa izixhobo ezizimeleyo kwaye bajonge igalelo layo.
Kutheni Kubalulekile Ukuba neQela Lokulawula?
Nangona iqela lolawulo lingafumani unyango, ludlala indima ebalulekileyo kwinkqubo yokulinga. Eli qela lisebenza njengendlela yokulinganisa, ukuvumela abaphandi ukuba baqhathanise iqela lokulinga kwiqela lokulawula ukuze babone uhlobo luni lempembelelo oluguquka kwiintlobo ezizimeleyo ezivelisiweyo.
Ngenxa yokuba abathathi-nxaxheba baye banikwe ngokulandelelana kwiqela lolawulo okanye iqela lokulinga, kunokucingelwa ukuba amaqela ayafana. Naluphi na ulwahlulo phakathi kwamaqela amabini ke umphumo weendlela zokuziphatha ezizimeleyo. Abahloli baqhuba inkqubo efanayo kunye namaqela amabini ngaphandle kolawulo lwezinto ezizimeleyo kwiqela lokulinga.
Umzekelo weqela loLawulo
Khawucinge ukuba umphandi unomdla ekufumaneni ukuba iziphazamiso ngexesha lokuvavanya zichaphazela iziphumo zokuvavanya. Umphandi angaqala ukuchaza ngokucacileyo ukuba bathetha ntoni ngeemphazamiso kunye nokwenza iingcamango . Kule meko, unokuchaza iziphazamiso njengenguqu kwiqondo lokushisa kwegumbi kunye nezinga lomsindo.
Iingcamango zakhe zokuba ngabafundi abakwiklasi elitshisayo nelitshizileyo baya kwenza okungakumbi ngaphezu kwabafundi kwigumbi eliqhelekileyo ngokubhekiselele kubushushu kunye nengxolo.
Ukuvavanya i-hypothesis yakhe, umphandi ukhetha i-pool yabathathi-nxaxheba bonke abathatha inqanaba elifanayo leklasi kwiklasi. Bonke abafundi banikwe umyalelo ofanayo kunye nezibonelelo ngexesha le-semester. Emva koko unika abadlali inxaxheba kwiqela lolawulo okanye iqela lokulinga.
Abafundi kwiqela elilawulayo bathatha uvavanyo lweematriki kwiklasi yabo eqhelekileyo. Igumbi lithe cwaka ixesha lokuvavanya kwaye ukushisa kwegumbi kufakwe njenge-comfortable degrees Fahrenheit.
Kulo qela lokulinga, abafundi bathabatha uvavanyo olufanayo ngokufanayo kwiklasi elifanayo, kodwa ngeli xesha iimpendulo ezizimeleyo zilawulwa ngumhloli. Uchungechunge lokuvakala, ukuvakala kwengxolo kuveliswa eklasini ngasemnyango, udala uluvo lokuba olunye uhlobo lomsebenzi wokwakha luqhubeka. Ngelo xesha, i-thermostat ikhankanywe kwi-degrees Fahrenheit.
Njengoko ubona, iinkqubo kunye nezinto ezisetyenziselwa kokubili kunye neqela lokulinga zifana. Umphandi usetyenzise igumbi elifanayo, iinkqubo zolawulo olufanayo kunye novavanyo olufanayo kumaqela amabini.
Into ehlukile eyahlukileyo ngumlinganiselo wokuphazamiseka owenziwe ngamanqanaba engxolo kunye nobushushu begumbi kwiqela lokulinga.
Emva kokuba uvavanyo luphelile, umphandi angakwazi ukujonga iziphumo zovavanyo kwaye aqale ukuthelekisa phakathi kweqela lolawulo kunye neqela lokulinga. Oko akufumanisayo kukuba amanqaku okuvavanywa kwiimvavanyo zezibalo ayephantsi kakhulu kwiqela lokulinga kunokuba babekho kwiqela lokulawula. Iziphumo zixhasa i-hypothesis yokuba iziphazamiso ezinjengeentsimbi ezingaphezulu kunye nobushushu zingathintela amanqaku okuvavanya.
