Cov txheej txheem kev tshawb fawb muaj xws li kev soj ntsuam zoo, ntsuas kom muaj nuj nqis, sorting/classification, inferring, predicting, experimenting, thiab kev sib txuas lus.
Ua raws li qhov kev pom no, dab tsi yog 8 cov txheej txheem science?
Cov ntsiab lus hauv cov teeb no (8)
- Kev soj ntsuam. siv ib los yog ntau tshaj ntawm tsib qhov kev xav kom pom cov khoom ntawm cov khoom lossis cov xwm txheej.
- Inferring.
- Kev faib tawm.
- Siv Tus lej.
- Ntsuas / Metrics.
- Siv Qhov Chaw / Sijhawm Kev Sib Raug Zoo.
- Kev sib txuas lus.
- Kev kwv yees.
Ib yam li ntawd, 12 cov txuj ci txheej txheem science yog dab tsi? Dab tsi yog cov txheej txheem kev kawm txuj ci hauv cov tub ntxhais kawm Daim Ntawv 2 hauv txhua qhov ntawm 12 cov txuj ci kev kawm txuj ci: Kev Saib Xyuas, Kev faib tawm, Kev ntsuas thiab siv tus lej, Inferring, Predicting, Sib txuas lus, Siv Space-Time Relationship, Txhais cov ntaub ntawv, txhais ua hauj lwm, tswj kev sib txawv, Hypothesising, Yog li ntawd, 6 cov txheej txheem kev kawm txuj ci tseem ceeb yog dab tsi?
6 Kev Kawm Txuj Ci Txuj Ci
- Kev soj ntsuam. Qhov no yog qhov txuj ci tseem ceeb tshaj plaws hauv kev tshawb fawb.
- Kev sib txuas lus. Nws yog ib qho tseem ceeb uas yuav tsum muaj peev xwm qhia peb cov kev paub dhau los.
- Kev faib tawm. Tom qab ua kev soj ntsuam nws yog ib qho tseem ceeb kom pom qhov zoo sib xws, qhov sib txawv, thiab pab pawg khoom raws li lub hom phiaj.
- Inferring.
- Kev ntsuas.
- Kev kwv yees.
Dab tsi yog 10 cov txheej txheem kev tshawb fawb yooj yim?
