STEM sawv cev rau Science, Technology, Engineering, thiab Math, tab sis dab tsi STEM kev kawm tsom mus rau ntau dua li plaub yam no. STEM Cov khoom ua si txhawb cov menyuam yaus los tsim kev txawj ntse hauv cov kev qhuab qhia tseem ceeb ntawm kev tshawb fawb, thev naus laus zis, engineering, thiab lej.
Ib yam li ntawd, koj tuaj yeem nug, qee yam haujlwm STEM yog dab tsi?
Ntau yam STEM
- Tiny Dancers (Science)
- Tsim ib lub roob hluav taws (Science)
- Apple Oxidation (Kev Tshawb Fawb)
- Lub Pob Zeb Scratch Test (Science)
- Tsim Ib Qhov Chaw Me Me Los nag (Technology & Engineering)
- Tsim Lub Tshuab Pulley (Technology & Engineering)
- Nyiaj Lej (Math)
- Daim iav Symmetry (Math)
Qhov thib ob, cov khoom ua si qia zoo tshaj plaws yog dab tsi? Peb Cov Picks
- Snap Circuits Jr.
- Anki Cosmo ntawm Amazon.
- Ozobot Bit Coding Robot ntawm Amazon.
- Magna-Vuas, Xim Xim, 100-Tej Teeb ntawm Amazon.
- GoldieBlox thiab Dunk Tank ntawm Amazon.
- 4M Dej Rocket Kit ntawm Amazon.
- Scientific Explorer Crime Catchers Spy Science Kit ntawm Amazon.
- Osmo Genius Kit ntawm Amazon.
Ib yam li ntawd, tej zaum koj yuav nug, koj yuav ua li cas thiaj tsim tau ib txoj haujlwm qia?
Hauv qab no yog yim txoj hauv kev zoo rau ROCK STEM
- Ua cov dej num sib koom tes. Cov kev ua ub no yuav tsum muaj kev kawm roll-up-koj-sleeves. Lawv yuav tsum yog hais txog kev ua.
- Txhim khu kev ua ub no nrog kev siv tshuab. Siv nws los yog tsim nws! Kev siv thev naus laus zis txhais tau tias ntau dua li tsuas yog nthuav qhia zaj lus qhia ntawm IWB lossis siv lub koob yees duab cov ntaub ntawv.
STEM project raws li kev kawm yog dab tsi?
Science, Technology, Engineering, thiab Mathematics ( STEM ) Qhov project - Raws li Kev Kawm ( PBL ) muab cov qauv tsim qauv engineering nrog rau cov ntaub ntawv kawm K-16.

Dab tsi yog qhov txawv ntawm kev tswj qhov xwm txheej thiab kev tswj xyuas qhov xwm txheej loj?
Yog li MI yog hais txog kev lees paub tias qhov xwm txheej ib txwm muaj thiab Kev Tswj Xyuas Teeb Meem yuav tsis txiav nws. Ib qho xwm txheej loj yog kev tshaj tawm ntawm lub xeev xwm txheej ceev. Ib qho xwm txheej loj yog nruab nrab ntawm qhov xwm txheej ib txwm muaj thiab kev puas tsuaj (qhov twg IT Service Continuity Management txheej txheem pib)
Dab tsi yog qhov sib txawv loj ntawm kev txheeb xyuas qhov yuam kev thiab kev kho cov lej yuam kev?
Ob qhov kev tshawb nrhiav qhov yuam kev thiab kev kho qhov yuam kev yuav tsum muaj qee qhov ntawm cov ntaub ntawv rov qab xa mus nrog cov ntaub ntawv tiag tiag; kev kho yuav tsum muaj ntau tshaj li kev tshawb nrhiav. Parity bits yog ib txoj hauv kev yooj yim rau kev tshawb nrhiav qhov yuam kev. Ib qho parity me ntsis yog ib qho ntxiv me ntsis xa nrog cov ntaub ntawv uas tsuas yog 1-ntsis suav ntawm cov ntaub ntawv
Dab tsi yog qhov dav thawj qhov kev tshawb nrhiav thiab qhov tob thawj qhov kev tshawb fawb?
BFS sawv rau Breadth First Search. DFS sawv cev rau Kev Tshawb Nrhiav Qhov tob. 2. BFS (Breadth First Search) siv Queue cov qauv ntaub ntawv los nrhiav txoj hauv kev luv tshaj. BFS tuaj yeem siv los nrhiav ib qhov chaw luv tshaj plaws hauv cov duab tsis hnyav, vim tias hauv BFS, peb mus txog qhov kawg uas muaj qhov tsawg kawg nkaus ntawm cov npoo los ntawm qhov chaw vertex
Dab tsi yog qhov qub txeeg qub teg Dab tsi yog qhov sib txawv ntawm qhov qub txeeg qub teg piav nrog piv txwv?
Inheritance yog ib txoj hauv kev kom tau txais cov yam ntxwv thiab kev coj cwj pwm ntawm ib chav kawm los ntawm lwm chav kawm. Cov chav kawm uas cov tswv cuab tau txais qub txeeg qub teg yog hu ua chav kawm hauv paus, thiab chav kawm uas tau txais cov tswv cuab tam sim no hu ua chav derived. Inheritance siv IS-A kev sib raug zoo
Dab tsi yog qhov kev txwv kev ncaj ncees piav qhia txog kev ncaj ncees lossis kev txwv txawv teb chaws?
Kev lees paub ncaj ncees xav kom tus yuam sij txawv teb chaws yuav tsum muaj tus yuam sij tseem ceeb sib xws lossis nws yuav tsum yog null. Qhov kev txwv no tau teev tseg ntawm ob lub rooj (niam txiv thiab menyuam); nws tuav cov ntawv xov xwm ntawm kab hauv cov rooj no. Nws txhais tau hais tias kev siv los ntawm kab hauv ib lub rooj mus rau lwm lub rooj yuav tsum siv tau
