The disagreement among language teaching methods had made grammar instruction a subject of controversy. Language teachers therefore are confused and split in to groups. The paradoxes also lead them to create their own personal theories about how to approach grammar based on their perceptions of grammar and grammar teaching. Assessing teachers’ perceptions in this regard has been attracting considerable research interest.However, it is necessary for stakeholders in the field to be aware of students’ perceptions as well. Exploring their perceptions, however, should not be the final job; once their perceptions are explored, they would be compared and contrasted to reach on consensus and to avoid mismatch. This book therefore explores and compares teachers’ and students’ perceptions of effective grammar teaching.
