Har birjamiyatning kelajagi uning ajralmas qismi va hayotiy zarurati bo' lgan ta' lim tizimining qay darajada rivojlanganligi bilan belgilanadi. Bugungi kunda mustaqil taraqqiyot y o' lidan borayotgan mamlakatimizning uzluksiz talim tizimini isi oh qilish va takomillashtirish, yangi sifat bosqichiga ko'tarish, unga ilg' or pedagogik va axborot texnologiyalarini joriy qilish hamda ta' lim samaradorligini oshirish davlat siyosati darajasiga ko' tarildi. “Ta lim to' g'risida”gi Qonun va “Kadrlar tayyorlash milliy dasturi”ning qabul qilinishi bilan uzluksiz ta lim tizimi orqali zamonaviy kadrlar tayyorlashning asosi yaratildi.
Ta' limning barcha bosqichlariga oid umumiy pedagogik va didaktik talab o' quvchining dasturiy bilim, tasavvur va ko' nikmalari asosida mustaqil ishlash samaradorligini takomillashtirish, ilmiy fikrlashga, o'quv faniga qiziqishini kuchaytirish, kasbiy bilimlarini chuqurlashtirish, nazariy va amaliy mashg' ulot mobaynida ularning faolligini oshirishdan iboratdir. Jahon pedagogik tajribasi, zamonaviy pedagogik texnologiyalarining o' quvchilarni fanlarga qiziqtirishga, ularning mustaqil ishlashda faolliklarini oshirishga imkoniyati cheksiz ekanligini tasdiqlamoqda.
O’zbekiston Pespublikasi Prezidenti Sh.Mirziyayevning Oliy majlisga murojatnomasida ta’kidlaganidek: ”Sharq donishmandlari aytganlaridek eng katta boylik-bu aql-zakovot va ilm,eng katta meros-bu yaxshi tarbiya,eng katta qashshoqlik bu bilimsizlikdir. Shu sababli hammamiz uchun zamonaviy bilimlarni o’zlashtirish,chinakam ma’rifat va yuksak madaniyat egasi bo’lish uzluksiz hayotiy ehtiyojga aylanishi kerak.taraqqiyotga erishish uchun raqamli bilimlar va zamonaviy axborot texnologiyalarini egallashimiz zarur va shart. Bu bizga yuksalishning eng qisqa yo’llaridan birini berish imkoniyatini beradi”.
2020-yil ilm marifat va raqamli iqtisodiyotning rivojlantirish yili bo’lib, bu yilda ta’lim sohasiga alohida e’tibor qaratilmoqda. Shunday ekan ta lim sohasida amalga oshirilayotgan islohotlarning bosh maqsadi va harakatga keltiruvchi kuchi har tomonlama rivojlangan barkamol insonni tarbiyashdan iboratdir.
Shunday ekan har tomonlama kuchli, bilimli,qobiliyatli, har qanday muammolarni yechimini topa oladigan olimlar,doktorlar, farmatsevlar,texnologlar kimyogarlarni yetishib chiqishida o’quvchilarni kimyo fanidan o’zlashtiradigan amaliy bilimlarini mustahkamlash muhim ahamiyatga ega. Buning uchun esa, o’quvchilarni pisa asosida amaliyot bilan bog’liq bo’lgan masala yechish kompetensiyalarini rivojlantirish zarur.
1-misol. Tuzning 16 ¹¹C va 25 ¹¹C dagi eruvchanlik koeffitsiyentlari 25 va 45 ga teng. 16 ¹¹ C li suvga 10 g tuz eritilib to’yingan eritma olindi. Eritma temperaturasi 25 ¹¹ C gacha oshirildi va eritmada tuz eritilib to’yintirildi. Olingan eritma 10 ¹¹C gacha sovutilganda 14,4 g tuz cho’kmaga tushdi. Tuzning 10 ¹¹C dagi eruvchanlik koeffitsiyentini aniqlang.
Yechish:
t=10"C t=16"C t=25"C

Tuz	lOgrtuz	tuz
HqO	hqo	hqo

S=? S=25 S=45

Ma’lumki harorat ko’tarilishi bilan tuzlaming eruvchanlik koeffitsienti ham ortadi.
16"C da 2-idishda 100 gr suvda 25 gr tuz erib,to’yingan eritma hosil bo’lsa, X gr suvda 10 gr tuz x=100* 10/25=40 gr suv mavjud.
Demak, 2-idishda 40 gr suv bo’lsa, 1- va 3-idishda ham 40gr dan suv bo’ladi.
25"C da 3-idishda 100 gr suvda 25 gr tuz erib,to’yingan eritma hosil bo’lsa, 40 gr suvda Y gr tuz Y=40*25/100=18gr tuz mavjud.
10"C da l-idishda,m(tuz)=l8-14,4=3,6 gr 100 gr suvda z gr tuz erib,to’yingan eritma hosil bo’lsa, 40 gr suvda 3,6 gr tuz Y=40*25/100=18gr tuz mavjud. Z=100*3.6/40=9 gr
