Mandi M. Johnson (2013) studied about “The relationship between reading fluency ,spelling ability and knowledge in elementary students” The aim of this study was to determine the effects spelling has on reading fluency and reading knowledge, various studies must be analyzed and discussed to identify the most proficient practices elementary teachers can amalgamate into their classrooms. Teachers who instrument effective practices into their classrooms should see reorganization during their students’ spelling skills. As reading fluency, spelling skills improve, and knowledge should improve. Different strategies and methods have also been diagnosed to see which are the most proficient for elementary students. Some teachers feel that spelling is not an important constitutive in the curriculum. Doing some research, spelling is a critical component not only in comprehension and reading fluency, but also across the curriculum in all subject areas. In addition, he said that if the student often practices the words by reading, the students will spell the words fluently and word learning will be increased.
