What should I do so that my students write and remember correct spellings of the English words?

Spellings are a big issue even in the native English speaking students. The best option to overcome this problem is use of Phonics. A little practice of using letters by concentrating on the sound of the word helps a lot. 

While writing, the issue of spellings become more grievous. Many people know proper spellings of a certain word but they misspell it when writing. Solution to this problem is to develop a habit of saying the letters of words with your tongue when writing. This conscious effort gives much better results.

Concentrate on making odd spelling vocabulary a part of your every day regular classes and highlight them to your students.

Divide long vocabulary into simple syllabuses and go one syllabus at a time.

Give them dictations, ask tem to read more and listen to music more

for that first you should tell the student sound of letters and you must pronounce the word correct then they must remember well and write without spelling mistake

Thanks for the invite,

Language experts say that learners should practice oral vocabulary before they proceed to writing and reading. Thus, the instructor needs to work hard on developing students' oral vocabulary to ensure they could recognise the words, and then writing and remembering correct spellings of such words will not be so difficult.

Dividing long words into simple syllabuses could be very useful.
