The purpose of this paper is to share the effectiveness of the word study program "Words Their Way" (Bear et. al., 2008) to improve spelling retention of first graders in a regular education classroom in the Spring of 2012. After implementing a traditional spelling program and seeing students continuously spell previous spelling words wrong, different word study programs were researched and decided "Words Their Way" (Bear et. al., 2008) was a viable option. Therefore, "Words Their Way" (Bear et. al., 2008) was implemented. The data tools used were: spelling pre and post tests, teacher made tests, checklists, Likert scales, anecdotal records, writing artifacts, teacher student interviews, and a teacher journal. . Students were grouped according to their stage in spelling development and instructed accordingly. It was shown "Words Their Way" (Bear et. al., 2008) allows individualized instruction to meet the development spelling levels of all students. Appended are: (1) Research Questions; (2) Pre and Post Test; (3) Teacher Made Tests--Weekly Spelling Tests; (4) Checklist; (5) Student Survey; (6) Anecdotal Record Form; (7) Writing Artifact Rubric; (8) Teacher Student Interview; and (9) Teacher Journal.
