Leej twg npaj txhua tus qauv atomic?
THIAB yog tias lawv twb paub lawm tias cov hluav taws xob me me thiab qhov tsis zoo, ces lub atom yuav tsum muaj cov nucleus zoo me me nrog cov electrons nyob ib puag ncig lawv. Tus qauv qhia los ntawm Niels Bohr yog ib qho uas koj yuav pom hauv ntau cov lus qhia txog kev tshawb fawb.
leej twg yog leej txiv ntawm tus qauv atomic?
Lub tswv yim hais tias txhua yam yog ua los ntawm atoms yog pioneered los ntawm John D alton (1766-1844) nyob rau hauv ib phau ntawv nws luam tawm nyob rau hauv 1808. Tej zaum nws yog hu ua "txiv" ntawm atomic txoj kev xav, tab sis txiav txim los ntawm daim duab no ntawm txoj cai "txiv yawg" tej zaum yuav yog lub ntsiab lus zoo dua.
John D alton atomic theory yog leej twg?
D alton's atomic theory yog thawj zaug ua tiav los piav qhia txhua yam teeb meem ntawm atoms thiab lawv cov khoom. D alton ua raws li nws txoj kev xav ntawm txoj cai ntawm kev txuag ntawm huab hwm coj thiab kev cai lij choj ntawm qhov muaj pes tsawg leeg. Thawj ntu ntawm nws txoj kev xav tau hais tias txhua yam teeb meem yog ua los ntawm atoms, uas yog indivisible.

Leej twg tau npaj ob chav helical qauv ntawm dna?
In 1953, Francis Crick thiab James Watson thawj zaug piav txog cov qauv molecular ntawm DNA, uas lawv hu ua "ob chav helix," hauv phau ntawv journal Nature. Rau qhov kev tshawb pom no, Watson, Crick, thiab lawv cov npoj yaig Maurice Wilkins Maurice Wilkins Nws tau paub zoo tshaj plaws rau nws txoj haujlwm ntawm King's College London ntawm tus qauv ntawm DNA.
Leej twg qhia tus qauv kev qhuab qhia tus kheej?
Skinner's Kev Tshawb Fawb thiab Tib Neeg Tus Cwj Pwm muab kev tshawb fawb ntawm cuaj pawg ntawm txoj kev tswj tus kheej. Leej twg nrhiav tau kev qhuab ntuas? Ntau tshaj 40 xyoo dhau los, W alter Mischel, PhD, tus kws kho mob hlwb tam sim no ntawm Columbia University, tshawb nrhiav kev tswj tus kheej hauv cov menyuam yaus nrog kev sim yooj yim tab sis ua tau zoo.

Puas muaj tus qauv tsim qauv?
Modular tsim, lossis modularity hauv kev tsim, yog lub hauv paus ntsiab lus tsim qauv uas faib cov txheej txheem rau hauv me me hu ua modules, uas tuaj yeem tsim, hloov kho, hloov, lossis pauv nrog lwm cov qauv lossis ntawm cov tshuab sib txawv.
Thaum lub sijhawm tsom xam ntawm tus qauv addie tus tsim qauv?
Tus qauv ADDIE yog cov txheej txheem dav dav uas ib txwm siv los ntawm cov kws tsim qauv qhia thiab cov neeg tsim kev cob qhia. Tsib theem- Kev tshuaj xyuas, Tsim, Kev Txhim Kho, Kev Ua Haujlwm, thiab Kev Ntsuam Xyuas - sawv cev rau cov lus qhia zoo, hloov tau yooj yim rau kev tsim cov kev cob qhia zoo thiab cov cuab yeej txhawb nqa kev ua tau zoo.
