Students tend to display noticeable inadequacy of comprehension and communication. Several research projects have been carried out to find suitable methods to enrich and enhance the vocabulary repertoire. The researchers have attempted the present study to find out whether using complex passages and different instructional methods to teach vocabulary enhances learning and internalization of the target vocabulary. Jigsaw, a student-centered method of instruction and the traditional method of instruction were adopted for both the groups and the design followed as repeated measures. The paired test of the data collected shows invariably the unavailing nature of both methods of instruction and complex input on students’ vocabulary.
This research work concludes that teaching methods tend to have insignificant impact on vocabulary enhancement when complex input passages are chosen. This research will cover all the details about how the teacher can use jigsaw techniques in teaching English as foreign language. The research aims to help students learn cooperation as group members share responsibility for each other's learning by using critical thinking and social skills to complete an assignment. This research will consist of four sections and rounds of concluding remarks as well as references.
