Kafukufuku akusonyeza kuti malo omveka bwino a mawu amatha kuwonjezera luso la ophunzira pophunzira ndi 30% komanso kutenga nawo mbali m'kalasi ndi 40%.

M'makalasi akale, ophunzira omwe ali m'mizere yakumbuyo nthawi zambiri amaphonya mfundo zazikulu za chidziwitso chifukwa cha kusawoneka bwino kwa aphunzitsi, zomwe zakhala chotchinga chobisika chomwe chimakhudza kufanana kwa maphunziro. Ndi kukula kwa chidziwitso cha maphunziro, makina amawu ogawidwa bwino kwambiri akukhala mawonekedwe wamba m'makalasi anzeru, zomwe zimathandiza wophunzira aliyense kusangalala ndi chidziwitso chofanana pakumvetsera kudzera munjira zaukadaulo.

Ubwino waukulu wa makina olankhulira ogawidwa uli mu luso lake lowongolera bwino malo olankhulira. Mwa kugawa ma speaker angapo mofanana padenga la kalasi, zimapangitsa kuti mphamvu ya mawu ifalikire mofanana, kuonetsetsa kuti ophunzira omwe ali m'mizere yakutsogolo ndi yakumbuyo amatha kumva nkhani zomveka bwino komanso zofanana. Kapangidwe kameneka kamathetsa vuto la malo olankhulira osagwirizana lomwe limapezeka m'makina achikhalidwe a sipika imodzi, komwe mizere yakutsogolo imamva mawu ambiri pomwe mizere yakumbuyo imavutika kumva bwino.

Dongosolo la amplifier limagwira ntchito yofunika kwambiri pakutsimikizira kuti mawu ndi abwino. Amplifier ya digito yopangidwira maphunziro imakhala ndi chiŵerengero chapamwamba cha ma signal-to-noise komanso mawonekedwe otsika opotoza, zomwe zimapangitsa kuti mawu a aphunzitsi azikhala enieni panthawi yokweza mawu. Kuphatikiza apo, amplifier iyenera kukhala ndi mphamvu zowongolera zodziyimira payokha za njira zambiri kuti isinthe voliyumu molondola m'malo osiyanasiyana ophunzitsira.

Purosesa yanzeru ya mawu ndi chida chachinsinsi chothandizira kumveketsa bwino mawu. Imatha kukonza mawu a aphunzitsi nthawi yeniyeni, kukweza makiyi a ma frequency, ndikuletsa mawu ndi phokoso la m'kalasi. Makamaka m'maholo akuluakulu ophunzirira, njira yochepetsera mayankho ya purosesayo imachotsa kulira, zomwe zimathandiza aphunzitsi kuyenda momasuka panthawi yophunzitsa popanda kuda nkhawa ndi nkhani zamawu.

Kapangidwe ka maikolofoni ndi kofunikira kwambiri pakugwira bwino ntchito pophunzitsa. Maikolofoni opanda zingwe amamasula aphunzitsi ku kufunika kogwira zida, zomwe zimawathandiza kulemba pa bolodi ndikugwiritsa ntchito zida zophunzitsira mosavuta. Maikolofoni otsogolera m'malo okambirana a ophunzira amajambula bwino zomwe wophunzira aliyense amalankhula, kuonetsetsa kuti maganizo onse alembedwa bwino panthawi yokambirana m'magulu. Zipangizo zapamwambazi zojambulira mawu zimapereka maziko aukadaulo ophunzitsira patali.

Mwachidule, makina olankhulirana ogawidwa m'makalasi anzeru ndi yankho lathunthu lomwe limaphatikiza kufalikira kwa mawu kofanana, kuwongolera kwanzeru kwa amplifier, komanso molondolapurosesa, ndi kunyamula maikolofoni momveka bwino. Sikuti zimangothetsa zopinga za kumva pa kufanana kwa maphunziro komanso zimapereka chithandizo champhamvu chaukadaulo pa njira zatsopano zophunzitsira monga kuphunzitsa kolumikizana komanso mgwirizano wakutali. Masiku ano pakulimbikitsa maphunziro amakono, kuyika ndalama pakumanga makina apamwamba a mawu m'makalasi kumagwira ntchito ngati chitetezo chofunikira kwambiri pamaphunziro abwino komanso sitepe yothandiza pakukwaniritsa cholinga cha "kutsimikizira kuti mwana aliyense akhoza kusangalala ndi maphunziro abwino."
