KIRISH
Hozirgi ta’lim jarayonini texnologiyalar va axborotlarsiz tasavvur qilib bo’lmaydi. Shuning
uchun ham ayni vaqtda respublikamiz ijtimoiy hayotiga shiddatli tezlikda axborotlar oqimi kirib
kelmoqda. Bu axborotlarni tez su’ratlarda qabul qilib olish, ularni tahlil etish, qayta ishlash va
umumlashtirish hamda o’quvchiga yetkazib berishni yo’lgan qo’yish ta’lim tizimi oldida turgan
dolzarb muammolardan biri hisoblanadi. Ta’lim muassasalarida axborot ta’lim muhitini tashkil
etishni maqsadi tayyorlanayotgan mutaxxasisga bo’lajak o’qituvchi shaxsiga qo’yiladigan talablar
bilan bevosita bog’liq holda ishlab chiqiladi. Bevosita axborot texnologiyalaridan foydalangan
holda sinf darsliklari labaratoriyalarini virtual jarayonlar asosida tasavvur etishimiz va
qo’llashimiz mumkin.
TADQIQOT MATERIALLARI VA METODOLOGIYASI
Ushbu maqolada biz fizika dasrligidagi mavzularga asoslangan holda elektronning elektr
va magnit maydonlaridagi harakatini modellashtirish uchun quyidagicha dastur tuzamiz:
