Not so long 'time' (tutaj to slowo absolutnie nie pasuje, pomieszales...aa long time ago' z 'not too long ago') ago access to education was limited (tutaj wypadalo by powiedziec ze to tylko chodilo o specificzne grupy ludzi, edukacja zawsze byla dla bogatych).
To 'perform' (nie, tu masz zle slowo, i nie o tym myslisz, co masz na mysli to 'obtain') better results in learning teachers have higher expectation 'toward' (chociaz ja bym napisala 'towards') (dalabym przedimek) students. Is 'it' (nie, tutaj trzeba 'this') (przedimek) positive or negative phenomenon? I will discuss it in (przedimek) following paragraphs.
Firstly, pupils are overloaded with 'task' (ale chyba masz na mysli wiecej jak jeden). They 'come back' (lepsze slowo 'return') from 'schood' (ortog) and they have to 'spaend' (ortog) 'anotehr' (ortog) couple of hours on 'time consuming' (ja dalabym to tak 'time-consuming') homework.
'This' (zle slowo, tutaj IT) is commonly known that (przedimek) learning process has the 'highes' (ortog) intensity 'in' (lepiej 'at') a young age. It is not necessary to learn only from books, 'especcially' (ortog) 'in' (zle slowo, tutaj 'at') 'the' (zly przedimek, tutaj 'a') young age. It's even better when the kid 'develop' (cos tu nie tak z tym slowem, poszukaj inne) world by self observation.
On the other hand high expectations are (przedimek) 'adaventage' (ortog). Demanding teachers 'motivates' (to slowo odnosi sie do 'pupils' tutaj w l. mnogiej, to czasownik musi byc dostosowany do l. mnogiej) their pupils, and make them push (tutaj brakuje pare slow...themselves to) their limits. 'So' (nie, to lepiej bedzie jak to bedzie zdanie laczone z poprzednim, a nie osobne zdanie) students will perform better in their 'eductaion' (ortog) career 'becouse' (ortog) they will have developed 'an' (nie,m tutaj 'a') habit to always work hard.
What is worth 'to mention' (nie, tutaj 'mentioning is) that schools tend to 'learn' (nie, to zle slowo, tutaj 'teach',...a teacher teaches, a student learns) unpractical knowledge, 'wich' (ortog) is also too 'much' (nie, to jest niepotr slowo) detailed. Learning 'programme' (mnie tutaj pokazuje blad ortog, chociaz ja bym to zostawila jak jest) is often 'obsolate' (ortog). Nowadays when the (mozna tutaj dodac 'information') technology is 'high' (nie, slowo to 'highly')-developed, lots of information can be found on the internet, so some of the things 'needn't have' (nie, to jest maslo maslane a wystarczy ..do not need) to be learned. Moreover (przecinek) after a short time that knowledge is forgotten and (przedimek) devoted time wasted.
Schools should teach only 'essential' (musisz dokladne wytlumaczyc co to jest) things. In (tutaj mozna dodac 'highly') developed technology era, pupils can easily learn from the internet.
