How to improve the reading skills of students?
Leesa: Good answer. You do need to consider the existing reading level when choosing the reading material. Also (at least it helped me) is to keep a notebook handy and write down each word or reference that you don't know. My 6th grade teacher claimed that if the book had no unfamiliar words it was too easy for you.
Encourage your students to read selected material and then discuss it in relation to other books, movies, news items, or TV shows. Have your students make the comparison: What did they like about how each format portrayed the topic? How would they have changed a format to better match the topic? What was the message the writers intended the reader/observer to get from the material? Being able to connect what has been read to something else in their lives helps students think abstractly about the material.
Support your students. And give more practical knowledge and experimental studies. That only give experience in own way.
Give strength motivation to your students, Keep on practice and learn new things their new way, Go with their moves and ideas and support.
