This action research focuses on improving students' ability to use verb tenses correctly when writing essays. A pre-test of 30 students showed they made many errors with verb tenses. Lessons were conducted drilling the usage of different tenses and a 3-step approach was used to help students identify and correct their own errors. A post-test found students made fewer errors, showing improvement in their writing skills and understanding of verb tenses after the lessons and 3-step approach.
