Grammar teaching and learning is an important component to get mastery over any language. English language is being taught as first, second or foreign language in many countries. Consider whether inductive or deductive teaching is more effective for learning English grammar as a second language is a topic for contemplation. This study aimed to investigate the effectiveness of inductive and deductive teaching for learning English grammar at undergraduate level. An experimental study was carried out through pre-test post-test control group design. Eighty male undergraduate Urdu speaking students were divided into two equal groups randomly. Group A was taught English grammar -- tenses and modal verbs through inductive teaching and group B through deductive teaching method. Pretest and post-test scores of both groups revealed that group A performed better than group B in learning English grammar -- tenses and modal verbs. It reveals that inductive teaching for learning English grammar -- tenses and modal verbs at undergraduate level is more effective than deductive teaching. Inductive teaching is recommended for teaching English grammar at undergraduate level.
