Cov Khoom Siv Kev Kawm: Hla -Txoj Kev Sib Txuas Ntawm Xwm thiab Coding
Lub ntsiab lus ntawm magneticcobblestonesculptures los ua ke nyob rau hauv lub tsev "ntau-dimensional kawm scenarios." Cov khoom siv suav nrog ob lub ntsiab lus tseem ceeb: cov pob zeb ntuj (3-}5cm inch, polished nrog cov hlau nplaum neodymium embedded) thiab programmable tswj hauv paus. Txhua lub pob zeb muaj 2000-gauss neodymium hlau nplaum-muaj zog txaus los ua kom ruaj khov 拼接 (txhawb txog li 10 lub pob zeb zoo sib xws) thaum ua rau lub hauv paus sensors ntawm kev sib nqus hloov.
Qhov tseem ceeb, nws qhib qhov programming interface: lub hauv paus yog sib xws nrog Arduino qhib- qhov chaw platform, tso cai rau cov menyuam yaus siv cov duab kos duab (rau hnub nyoog 6-8) lossis cov programming code (rau cov hnub nyoog 9+) los teeb tsa sib nqus rhiab heev, lub teeb tawm tswv yim hom (nrog tsim - hauv RGB LEDs yooj yim), thiab txawm txuas. Piv txwv li, thaum ib qho tshwj xeeb cobblestone configuration tiav lawm, lub hauv paus teeb nyob rau hauv ib tug sib xws xim thiab plays kev cai suab teebmeem-seamlessly integrating "zoo li paub," "magnetism qauv," thiab "programming logic."
Kev paub txog kev txawj ntse: Kev txhawb nqa tseem ceeb hauv kev xav
Ib xyoo 2023 tswj kev sim los ntawm Singapore Ministry of Education tau lees paub cov khoom siv kev kawm tau zoo. Nws tau xaiv 480 tus thib peb- cov tub ntxhais kawm qib (8-9 xyoos) los ntawm 12 lub tsev kawm ntawv theem pib, muab faib ua pawg sim (siv cov khoom siv sib nqus cobblestone) thiab pab pawg tswj hwm (siv cov khoom siv hauv tsev). Ob pawg tau koom nrog 40-feeb kev tsim kho kev tsim kho ob zaug hauv ib lub lis piam rau 3 lub hlis.
Cov txiaj ntsig tau pom: pawg sim cov qhab nia hauv "spatial visualization tests" (piv txwv li, 3D zoo li kev sib hloov kev lees paub, ntau- ib feem ntawm kev xav) txhim kho los ntawm 35% piv rau kev sim ua ntej -, ntau dua li pawg tswj hwm 12%. Hauv "kev ntsuam xyuas kev xav hauv engineering" (piv txwv li, kev txheeb xyuas kev ruaj ntseg, kev daws teeb meem), qhov kev sim pab pawg neeg ua tau zoo tau mus txog 68%-ntau dua ob npaug ntawm pawg tswj hwm 31%. Cov kws qhia ntawv tawm tswv yim tau sau tseg tias qhov tsis sib xws ntawm cov pob zeb ntuj, piv rau cov qauv blocks, tau txais kev tshoov siab zoo dua rau cov menyuam yaus "kev sib xyaw ua ke" kev sim, thaum kev sib txuas ntawm cov hlau nplaum thiab coding ua rau "ua rau- cuam tshuam kev sib raug zoo" intuitively to taub.
Daim ntawv pov thawj kev nyab xeeb: Ib qho kev xaiv zoo rau niam txiv thiab tsev kawm ntawv
Rau cov menyuam yaus cov khoom lag luam muaj kev nyab xeeb, cov khoom siv sib nqus cobblestone dhau qhov kev sim nruj raws li EU tus qauv EN71-3 (cov khoom tshwj xeeb tsiv teb tsaws). Cov ntaub ntawv ntsuam xyuas pom tias cov hlau hnyav (lead, cadmium, mercury, thiab lwm yam) kev tsiv teb tsaws tsuas yog 0.002mg/kg-1/10 ntawm tus qauv txwv (0.02mg/kg) thiab zoo hauv qab qhov kev nyab xeeb thoob ntiaj teb.
Cov ntsiab lus tsim kuj tseem cuam tshuam txog kev nyab xeeb: cobblestone ntug undergo 1000-grit polishing, nrog nto roughness Ra<0.8μm to prevent scratches; embedded magnets are fully sealed in epoxy resin, remaining intact after 1000 drop tests (from 1.2m onto wooden floors); the base uses food-grade ABS plastic, heat-resistant up to 80℃, and is directly washable with water. These features make the kit suitable for both family parent-child interaction and school group teaching.
