Ngokufutshane

• Ewe, oku kuqhelekile, kwaye hayi, ngokuqhelekileyo akufakwanga kwiwaranti: iikhithi zeerobhothi zeklasi zisilela rhoqo, kwaye ubuncinane omnye umthengisi omkhulu uye wabala iimoto njenge"zinto eziphelayo" waza walikhaba ibango lewaranti likatitshala esekelwe koko.
• Amanani okwenene katitshala wesikolo esiphakathi: ezi-4 kwezi-32 zeemoto ze-VEX, ezixabisa i-$200, zaphuka kwiiveki ezili-10 zokuqala zokusetyenziswa. Leyo yireyithi ye-12.5% yokusilela kweemoto kwikota enye.
• Ezine ezinkulu ezibulalayo kukuxhatshazwa kweemoto, ukukhutshwa kombane ozinzileyo kwiibhodi zolawulo, izixhumi neepakethi zebhetri ezethe-ethe, kunye nokulahleka nje kwempahla.
• Izisombululo zitshiphu: thenga kubathengisi abathengisa iziqwenga ngazinye apha ekhaya, sebenzisa inkqubo yokutyikitya iikhithi ekuphumeni nasekubuyeni, fundisa imikhwa esisiseko yokuthintela umbane ozinzileyo, uze ugcine i-simulator yesikhangeli yasimahla njengeqhinga lokugcina ukuze ikhithi ephukileyo ingaze isirhoxise isifundo.
• Phambi kokuba uthenge, nika umthengisi ngamnye amanqaku ngokweenkcukacha zeziqwenga zokutshintsha, ukufumaneka apha ekhaya, ukomelela kwezixhumi, isimo sewaranti, kunye ne-simulator yokusabela. Itheyibhile engezantsi ibonisa indlela.

"Ezi ziimoto ze-$200 eziphuke kwiiveki ezili-10 zokuqala"

Ukuba ufundisa iirobhothi, sele uyazi le nkqubo. Iikhithi zifika ngoJanyuwari zikhangeleka ngathi azinakonakala. Ekupheleni kwekota yokuqala unedrowa ezele ziimoto ezifileyo, ibhodi yolawulo engavukiyo, kunye nesethi yeklasi engasakwazi ukwahlulwa ngokulinganayo ngamaqela. Nanku utitshala wesikolo esiphakathi echaza kanye loo nto kwi-VEX Forum:

"Kwiimoto ezi-32 kwiikhithi ezisi-8, ezi-4 ziphukile... Ezi ziimoto ze-$200 eziphuke kwiiveki ezili-10 zokuqala zokusetyenziswa"

— VEX Forum, "Incredibly Frustrated - Broken Motors", Matshi 2024

Into ehlabayo kuloo ngxoxo ayilorheyithi yokusilela. Kukuba inkxaso ye-VEX yabala iimoto njenge"zinto eziphelayo" yaza yasikhaba isicelo sewaranti. Iindawo irobhothi engenakushukuma ngaphandle kwazo zaphathwa ngathi ziyinki yomshicileli.

Iimoto sisiqalo nje. Kwicala le-micro:bit, iibhodi ngokwazo ziqinile, kodwa yonke into ezingqongileyo itya ixesha lokufundisa:

"Ndingutitshala we-STEM ofundisa ukukhowuda nge-micro:bit kwiiklasi zam zebanga lesi-7. Mhlawumbi ndichitha iyure ngemini yonke ndincedisa abafundi ukusombulula iingxaki zeepakethi zebhetri ezingasebenziyo. … Ndizamile ukuodola kubaboneleli abahlukeneyo, kodwa bonke babonakala bengamampunge."

— r/microbit, Okthobha 2024

Iyure ngemini ziiyure ezintlanu ngeveki zexesha likatitshala ofanelekileyo elichithwa ekuhlukuhleni iiklipsi zebhetri. Emva koko kukho ukusilela okungabonwa mntu kusenzeka:

"Salahlekelwa ziihub zolawulo ezi-3 kunyaka ophelileyo ngenxa yombane ozinzileyo"

— r/FTC, Matshi 2026

Kukho nokuncipha okucothayo okungaze kubonakale nakwesiphi na isibalo sokusilela:

"Ingxaki ephindaphindayo ibikukulahleka kwempahla ngenxa yokungakhathali nokungacingi okuqhelekileyo kwabantwana abakwishumi elivisayo."

— r/teaching, Februwari 2024

Loo titshala wokugqibela wayechaza "iibhokisi ezikwiibhokisi" zezixhobo ze-VEX, ze-Raspberry Pi naze-Arduino. Le nkqubo ayikhethi mthengisi. Yonke into iyaphuka, iyaphelelwa okanye iyanyamalala, kwaye iindleko zokuyitshintsha azizange zibe kuhlahlo-lwabiwo-mali.

Kutheni iikhithi zeklasi ziphuka, yaye kutheni iiwaranti zingakusindisi

Iimoto zenza owona msebenzi unzima zinolona khuseleko luncinci

Imoto ekwirobhothi yeklasi iyabanjezelwa ezindongeni, ijikelezwe ngasemva ngesandla, ize ifakwe kwiingalo abantwana abazeyamisa kuzo. Abathengisi bayakwazi oku, yiyo loo nto ulwimi "lwezinto eziphelayo" luvela kwiimpendulo zewaranti. Yiyo loo nto namaxabiso okutshintsha ebuhlungu. Omnye utitshala owayethelekisa iiplatifomu wayibeka ngokucacileyo:

"Ngendisebenzise i-LEGO Education/EV3/Spike Prime, kodwa ibiza kakhulu kakhulu (i-$400 ngekhithi nganye yemfundo) … Iimoto nazo zibiza kakhulu (kum) nge-$84."

— r/robotics, Janyuwari 2025

Xa imoto enye yokutshintsha ixabisa inxalenye ebalulekileyo yekhithi ipheleleyo, ukusilela ngakunye kuba yingxoxo yohlahlo-lwabiwo-mali endaweni yokutshintsha okuthatha imizuzu emihlanu.

Umbane ozinzileyo ngumbulali othuleyo weebhodi

Ukukhutshwa kombane ozinzileyo akudanyazi ngendlela ebonakalayo kumanqanaba ombane abulala i-hub yolawulo. Umfundi unyathela ikhaphethi emoyeni owomileyo wasebusika, achukumise i-pin header, ize ibhodi ebisebenza izolo ingaze iphinde ivuke. Ngenxa yokuba akukho monakalo ubonakalayo, oku kusilela kubonakala kungenambono, kubekwa ityala "kwizixhobo zombane ezitshiphu", kwaye phantse akufakwa kwiwaranti.

Izixhumi neepakethi zebhetri zisilela ngaphambi kwayo nayiphi na enye into

I-VEX Forum yodwa ibonisa ngaphezu kweengxoxo ezisibhozo ezahlukeneyo ngokusilela kwezixhobo zeklasi: iingqondo ze-V5 eziphukileyo, iipoti ezifileyo, izixhumi ze-micro-USB eziqhawukileyo. Ngokukodwa i-micro-USB ayizange yenzelwe ukuphathwa rhabaxa yonke imihla eklasini ngabantwana abaneminyaka elishumi elinesibini. Iipakethi zebhetri zabanye abavelisi lilo elo bali kwihlabathi le-micro:bit: iiklipsi ezitshiphu, iintambo ezicekethekileyo, kwaye akukho mgangatho osezantsi ofanayo kubo bonke ababoneleli.

Uhlahlo-lwabiwo-mali luhlawulela ukuthenga, hayi ukugcina izixhobo zisebenza

Izikolo zabela imali yosungulo olubengezelayo, hayi eyonyaka wesibini. Enye iposti ye-r/Teachers eyaxhaswa ngokubanzi (ii-upvote eziyi-164) yaxela uhlahlo-lwabiwo-mali lweminyaka emibini lwe-STEM nesayensi lwe-$100. Zizonke. Xa imali yeziqwenga zokutshintsha ingu-zero, imoto yokuqala ephukileyo iqalisa ukubala ukuhla: iikhithi ziyadityaniswa, amaqela akhula ngobungakanani, ize ekugqibeleni le nkqubo ife buthule kukho ikhabhathi ezele zizixhobo ezisebenza esiqingatheni. Kwizikolo zoMzantsi Afrika, yongeza isiphindi sokungenisa impahla: iziqwenga ezininzi zokutshintsha kufuneka zithunyelwe zivela kwamanye amazwe, nto leyo ethetha iiveki zokulinda kunye neentlawulo zecuntsu ngaphezu kwerandi ebuthathaka.

Okusebenza ngokwenene: isikhokelo sokulungiseka kwezixhobo

Awunakukwazi ukuthintela ukuphuka kweekhithi. Unako ukuthintela ukuba ukuphuka kurhoxise izifundo. Yahlula ingxaki ibe koko ukujongayo phambi kokuthenga nakoko ukwenzayo emva kokuthenga.

Phambi kokuba uthenge: uvavanyo lomthengisi lwemibuzo emihlanu

1. Ndingakwazi na ukuthenga imoto enye kanye? Hayi ipakethi enezine, hayi "ibhandeli yenkonzo". Ukuba eyona yunithi incinci onokuyithenga yikhithi, ukusilela ngakunye kukubiza ikhithi epheleleyo. Muka nje.
2. Ndingasifumana na apha ekhaya? Isiqwenga sokutshintsha esithunyelwa ngaphakathi elizweni sifika ngeentsuku. Esidlula kwicuntsu sifika ngeeveki size sibize ngaphezu kwexabiso elibhaliweyo. Kwizikolo zoMzantsi Afrika lo mbuzo mnye ulawula zonke iindleko zokuba nezi zixhobo.
3. Yintoni ephuka kuqala, kwaye incanyathiselwe njani? Buza ngokukodwa ngezixhumi. I-micro-USB kunye neeklipsi zebhetri ezibambelela ngokucinezela zaziwa njengeendawo ezisilelayo; izixhumi ezitshixayo okanye ezinesitshixo ziyakwazi ukumelana neklasi ngcono kakhulu.
4. Fumana isimo sewaranti sibhaliwe phantsi. Buza ngqo: ingaba iimoto zizinto eziphelayo? Ingaba ukusilela okubangelwa yi-ESD kufakiwe kwiwaranti? Impendulo yomthengisi phambi kwentengiso ixabiseke ngaphezu kwayo nayiphi na incwadana yokuthengisa.
5. Ingaba likhona iqhinga elingafuni zixhobo? Ukuba iplatifomu ine-simulator elungileyo, ikhithi ephukileyo iba yinkathazo nje endaweni yokuba sisifundo esilahlekileyo.

Emva kokuba uthengile: qhuba ilebhu njengethala leencwadi

• Nika inombolo ikhithi nganye nesiqwenga ngasinye esikhulu. Abafundi batyikitya xa bethatha iikhithi naxa bezibuyisa, kwaye imizuzu emibini yokugqibela yesifundo ngasinye ngoweyokubala iziqwenga. Eli lelona yeza laziwayo "lokungacingi okuqhelekileyo kwabantwana abakwishumi elivisayo".
• Fundisa imikhwa yokuthintela umbane ozinzileyo. Chukumisa into eyintsimbi phambi kokuphatha iibhodi, gcina iibhodi zisezingxoweni zazo xa zingasetyenziswa, kwaye ungaze uphathe izixhobo zombane phezu kwekhaphethi. Iihub zolawulo ezintathu ezifileyo zihlawulela iingxowa ezininzi zokukhusela kumbane ozinzileyo.
• Yekisa iibhetri phambi kokuba zibe yingxaki. Faka amaleyibhile kwiipakethi, ubhale imihla yazo, uze uzilahle ezo zingathembekanga. Iyure ngemini yokuhlola iibhetri ibiza ngaphezu kwayo nayiphi na ibhetri.
• Gcina ikhithi enye eyokunikela ngeziqwenga. Khetha ikhithi eza kuba ngumnikeli weziqwenga ukuze iikhithi ezisixhenxe ezisebenzayo zihlale zipheleleyo, endaweni yeekhithi ezisibhozo ezinye zonke ziswele isiqwenga.
• Yiba nesifundo se-simulator esilungele ukusetyenziswa. I-simulator yasimahla esebenza kwisikhangeli efana ne-sheen verse iqhuba i-MicroPython yokwenene kwiirobhothi ezenziweyo, ingafuni zixhobo kwaye ingafuni nokufakelwa. Gcina isifundo esinye se-simulator silungiselelwe iyunithi nganye, ize ukusilela kwezixhobo kuyeke ukuba yimeko yongxamiseko. Ungayivavanya kwimizuzu embalwa ku-/verse-try/en-us.

Indlela esiyisingatha ngayo le nto e-sheen

Inyaniso epheleleyo kuqala: izixhobo zethu nazo ziyaphuka eklasini. Zonke ziyaphuka. Umahluko esizama ukuwenza kukulungiseka. Yonke isensa naso sonke isiqwenga sokutshintsha se-sheenbot∞ sithengiswa ngasinye kwi-venkile yethu, sithunyelwe kuwo wonke uMzantsi Afrika, ngoko akukho ndleko zokuthumela zivela phesheya nasiphindi secuntsu, kwaye isensa esisilelayo kukutshintshwa kwemodyuli okuxabisa iirandi ezimbalwa oyifaka nje isebenze, endaweni yokutshintsha ikhithi yonke. Iwekshophu yethu yaseKapa yenza ukulungisa kwaneziqwenga ezenziwe ngokomyalelo. Kwizikolo eziqala phantsi, ukufumana nokusekwa kwelebhu kubandakanya konke ukufakelwa kuquka noqeqesho lootitshala, kwaye sheen verse isimahla kwisikhangeli njengecebo lokugcina elingafuni zixhobo konke konke.

Uthelekiso: ukunika amanqaku iindlela ezikhoyo ngokulungiseka kwazo

Eli likhadi lamanqaku esicebisa ukuba izikolo lisebenzise nakuwuphi na umthengisi, ligcwaliswe ngokweengxelo ezingasentla. Umqolo ngamnye unobuthathaka bokwenene, kubandakanya nowethu.

Imibuzo Ebuzwa Rhoqo

Ingaba iimoto zeekhithi zeerobhothi "zizinto eziphelayo" ngokwenene?

Ubuncinane omnye umthengisi omkhulu uye waziphatha ngaloo ndlela. Kwingxoxo ye-VEX Forum kaMatshi 2024, utitshala oweemoto zakhe zasilela zingekagqithi iiveki ezili-10 walikhatyelwa ibango lakhe lewaranti kuba inkxaso yayibale iimoto njengezinto eziphelayo. Nokuba uthenga kuwuphi na umthengisi, fumana impendulo yakhe ebhaliweyo kuloo mbuzo kanye phambi kokuba uhlawule.

Sisimalini isikolo esimele siyibekele iziqwenga zokutshintsha zeerobhothi?

Akukho mgangatho upapashiweyo, kodwa idatha yokwenene engasentla iyoyikeka: ezi-4 kwezi-32 zeemoto (i-12.5%) zasilela kwiiveki ezili-10 zokuqala kwiklasi enye. Umthetho osebenzayo kukufaka kuhlahlo-lwabiwo-mali lonyaka wokuqala ixabiso lesethi epheleleyo yeemoto, iintambo neepakethi zebhetri zazo zonke izixhobo zakho, uze ujonge ixabiso lesiqwenga esinye phambi kokukhetha umthengisi, hayi emva koko.

Yintoni ebulala iibhodi zolawulo zeerobhothi eklasini?

Abarhanelwa abaqhelekileyo kukukhutshwa kombane ozinzileyo, izixhumi eziqhawukileyo neengozi zebhetri. Elinye iqela le-FTC laxela ukuba lalahlekelwa ziihub zolawulo ezintathu ngonyaka omnye ngenxa yombane ozinzileyo kuphela. Imikhwa esisiseko ye-ESD, ukuchukumisa intsimbi kuqala, ukugcina iibhodi zisezingxoweni, ukungasebenzi phezu kwekhaphethi, ayibizi nto kwaye isusa eyona ndlela yokusilela ibiza kakhulu.

Ndingakuthintela njani ukulahleka nokophulwa kweziqwenga ngabafundi?

Qhuba ilebhu njengethala leencwadi. Nika inombolo ikhithi nganye, wenze abafundi batyikitye xa bethatha naxa bebuyisa iikhithi, uze uqukumbele isifundo ngasinye ngokubala iziqwenga imizuzu emibini. Ootitshala baxela ukuba ugcino olungalawulwanga lukhokelela ekulahlekeni kwempahla rhoqo, ngoko inkqubo yokutyikitya ukuthatha nokubuyisa ibaluleke njengokukhetha izixhobo.

Ndisenako na ukuqhuba isifundo seerobhothi ukuba iikhithi ziphukile?

Ewe, ukuba ulungiselele iqhinga le-simulator. Ii-simulator zasimahla zesikhangeli zithetha ukuba injongo yesifundo iyasinda nokuba izixhobo azisindanga. sheen verse iqhuba i-MicroPython yokwenene kwiirobhothi ezenziweyo ngaphandle kokufakela nantoni na, kwaye ungayizama simahla ku-/verse-try/en-us. Gcina inguqulelo enye ye-simulator yeyunithi nganye ilungile, ize iikhithi eziphukileyo ziyeke ukukubiza iintsuku zokufundisa.
