Hello. This text is very well written.  It follows a clear academic structure and is easy to understand.  So, rather than try to identify 'mistakes' I will try to redraft the text to appear a little more academic.  In many cases, there will be more than one way to say something.  This would be my approach:

The best way to improve the quality of education is to increase teachers' salaries.

Nowadays, education is a major social concern.  Education may be considered more important than ever.  Some parents believe that by increasing teachers' salaries their children may be better educated.  I disagree with this idea.  The impact of teachers on education has been decreasing and schools should spend their money on improving students' learning environment instead. 

To begin with, learning methods have changed. Now, students use a variety of devices in class, such as televisions, computers, projecters and so on.  While teachers may teach students how to use these facilities in order to get information that they need, students could learn by themselves by using these facilities to retrieve information at home.  For example, students can get up-to-dated information from the internet in accordance with their interests. while some teachers do not know how to used it in a proper way. (Sorry, im not sure of your meaning here.  Do you mean that teachers may be unable to use technology well enough to assist students?) Additionally, it is hard to say that teachers are students' only source of information. For example, students can learn from sources such as their friends and parents, not just teachers. This is because students may spend more time with their friends and parents

If people really want to improve the quality of education they should take the learning environment into their consideration. It can influence students' learning considerably. In order to offer students more opportunities to access a wide range of information, every school should establish a media center in which students can access technology independently. Schools should also offer extra-curricular activities for students as many important attributes, other than knowledge, are required to live in a society.  These attributes may include leadership, patience and teamwork. By attending extra-curricular activities offered in school, students can experience a small version of our society and learn how work well with other people.

To sum up, there are many effective ways to improve the quality of education.   Rather than increasing teachers' salaries, schools can provide state-of-the-art facilities so that students can acquire update-to-date knowledge as fast as possible. Moreover, participation in activities with their peers may help students further develop their social skills.

Hi Heewon,

Im sorry to hear that you are having a challenging time in the UK. I work with international students each summer as they enroll for a university in London and I have also been in the same situation myself when studying abroad. Remember that you will not be alone in this feeling. It is a common feeling for many students and completely natural. If you are a little brave just now Im sure that you will soon make many good friends.

One thing that many international students don't realize is that native students can be equally nervous to speak with international students. Everybody is afraid of being misunderstood, but in my experience there are very few communication problems once friends and classmates get to know each other.

If you don't understand what someone says, say something like <em>"Oh that's interesting, do you mean that .... ?'</em> rather than <em>"Sorry, i don't understand.  Can you say that again,</em> please?" 

Likewise, if you feel you haven't been understood, restate your point <em style="color: #ff0000;">"What I mean to say is that..."  </em>This phrase is a good way to save yourself, and others, the embarrassment of suggesting that there has been a misunderstanding.

In that case, should I .... (useful if you are unsure about an instruction)
Tell me more... (useful if someone is telling a story or describing something)

Generally, if you smile and ask people questions they will be happy to continue talking about themselves or their chosen topic.  The more questions you ask the more time you will have to think and the more clues you will recieve about the conversation. You dont have to be apologetic if there is a misunderstanding. 

My final tip is simply to be confident and smile. If you don't feel confident, then try to pretend that you are.  You have English speaking friends in Korea, so your English ability must be good.  Likewise, you wouldnt have recieved a study visa without sufficent grades in horrible English exams like IELTS. Im sure you can do it.  Good luck ^^

Personally, I'm in favour of trans-national / trans-cultural / trans-lingual relationships.

As was already mentioned, there may be issues that arise from time-to-time as a result of outsider influence, but that happens in mono-cultural relationships too.  

In my humble opinion, relationships are only going to be successful if both parties show respect, flexibility and understanding for each other. Perhaps there will be misunderstandings arising from cultural differences, but we could consider these as positive opportunties to learn and grow together as a couple.   Perhaps, transnational couples could be more understanding of differences within their relationship than mononational couples.

When you meet the right person, it really won't matter where they come from :) 

The Perks of Being a Wallflower

Hello. I am / was supposed to write something in English here everyday, but it's harder than I thought. Anyways, I would like to write about a / the movie that i watched today. it's  It was made in 2012 and the title is "The Perks of Being a Wallflower." The reason i watched this movie is that I'm having a hard time nowadays. (Not that really hard) Well, not that hard really. I know i will overcome this situation for sure, but you know to make my feel better I often watch (growth movie that teenagers came out) coming-of-age movies.

I did worried / used to worry about many things when i was in secondary school, such as grades, looks, social relationships, my future etc. The other way I was always mad at something but at least i had great years with my crazy friends which is will never (come back again) return. In teenager movies, most characters having have a hard time. (This facts gives me a catharsis)   These movies offer a means of catharsis for me.  And  By the end of the movie they(who? the movie or the characters?) started to show the bright side of their life. Growth Coming-of-age novels or movies always ends like this pattern. It makes me feel good all the time.

Even though, some of film critics didn't say positive things about this movie. I can say that it's good movie. Especially, the young actors were so attractive in the film. I think very highly of the three leading actors.

Hi Jooni,
This was an interesting little blog ^^ You're writing style is very relaxed and conversational.   You are using some interesting and specialised vocabulary too. Congratulations!

Be careful with the word <em>catharsis. </em> Both English and Korean borrow the word, 카타르시스 from Greek. However, in English it's considered a rather formal word, which seems out of place when used in your conversational writing style.  It may be more appropriate to use more simple language, such as, <em>These movies always help me relax.</em>

Overall, your writing in interesting and easy to understand.  Well done.  Good luck with your writing practice.  I'm supposed to practice my Korean writing everyday too, but I can always find something to distract me ~~

i have a question about english grammar!!

brazil is not only the most populous of the twelve country but also the largest in area

why 'in area' has to be corrected?

It is an ambiguous error, unfortunately.  Readers can identify the error, but will not be able to offer a precise correction without more information.  Sorry

Do you mean it is "the largest in terms of area." = in other words, it is the biggest of the 12 countries
Do you mean it is "the largest in the area." = it is the largest of the countries in close proximetry , for example in South America.
There may be other plausable corrections too.
 

This site has a list of useful resources for download http://asianthusiast.wordpress.com/language-resources/

Under the heading textbooks you will see Korean Grammar for International Learners and Using Korean: A Guide to Contemporary Usage available for download.  Perhaps, you could take a look at these textbooks and then decide which to buy.

I own both.  I tend to favour Korean Grammar for International Learners.  I find it more useful on a practical basis than Using Korean.
