Mtaala mpya shule za sekondari 2025

Image
 Taasisi ya elimu Tanzania (TET) Baada ya shule kufunguliwa haya ndio mambo ambayo taasisi ya elimu Tanzania TET na wizara ya elimu Tanzania wametaka wazazi, walimu na wadau wa elimu kuyajua kuhusu mchakato wa Mtaala mpya kwa shule za sekondari kwa mwaka 2025 Imesema kuwa mwaka 2025 mtaala mpya kuanza kutumika.  Katika Mtaala huu kuna mabadiliko machache kama vile. * Somo la civics kuondolewa na kuwekwa somo jipya la historia ya Tanzania na Bofya link/ kiungo hapo chini kutazama video ya maelekezo  https://youtube.com/shorts/0l1eIOVX6qs?feature=share maadili. Somo hili litafundishwa kwa lugha ya kiswahili kuanzia kidato cha kwanza mwaka huu 2025. *Somo la commerce kuondolewa na kuanzishwa kwa somo jipya la elimu ya biashara (business education) Wizara ya elimu na taasisi ya elimu imefanikiwa kuanzisha Mtaala huu mpya kwa mwaka huu 2025 Pia elimu ya amali (mafunzo ya ufundi) nayo kuanzishwa kwa baadhi ya shule, hii ni kutaka kuwajengea wanafunzi uwezo wa ubunifu na ujuzi ...

PHYSICS MTAALA MPYA, NI MZURI NA NI WA KUJENGA KAMA WANAFUNZI WATAFANYA KWA VITENDO

Image
Taasisi ya elimu Tanzania Mwaka 2025  Umetoa muongozo jinsi ya mtaala ulioboreshwa wa elimu ya sekondari utakavyokuwa, hasa kwenye somo la fizikia ambalo limesisitizwa kuwa liwe ni somo linalojenga maarifa ya vitendo ili kuandaa wanafunzi ambao wataweza kuendana na kasi ya maendeleo ya sayansi na teknolojia. Wadau wa elimu wanatakiwa kusimamia hilo ili kuwajengea wanafunzi umahiri mkubwa katika masomo ya sayansi ikiwemo fizikia. Sisi pia kama wadau wa elimu Tanzania tutakuwa tunakuletea machapisho mbalimbali ambayo yatakuwa yakakusaidia namna ya kufundisha somo la fizikia na kulifanya kwa vitendo Ili kuweza kuwajengea wanafunzi uwezo wa ubunifu katika nyanja mbalimbali. Machapisho yetu yakakusaidia mdau wa elimu, mwanafunzi na mwalimu katika harakati za kutekeleza mtaala ulioboreshwa. Hapa tutakuletea namna ya kujibu maswali ya fizikia katika mtaala mpya ulioboreshwa wa competance based. Maada zilizomo katika kitabu cha physics kidato cha kwanza katika mtaala ulioboreshwa  1. ...
