SUMMARY
Human beings, since they first met different languages and cultures, have had an urge to learn those languages and cultures. In modern societies, this urge has currently turned into a necessity. As a result of this necessity, the supply-demand balance has changed and the rate of language learning and acquiring new cultures have increased parallel to the rising world population. All these developments required the language teaching and learning process to be implemented as a scientific discipline. A plethora of different methods have emerged and shaped on the basis of scientific data. One of these methods is “Task-based Language Teaching (TBLT)”. This method was introduced in the last quarter of 20th century and has still been widely used in language teaching today.In this study, we tried to teach new terms and phrases to C1 level learners learning Turkish as a second language with task-centered activities formed in compliance with the principles of task-based language teaching method. Terms and phrases are vital for C1 level learners to be an independent performer of the language in the four basic skills of the language.Two discrete sections form up this study. In the first section, literature review and general information about task-based language teaching method are introduced. In the latter, there are seven sample activities formed with regard to the instructional design of task-based language teaching method. In these activities, we tried to teach terms and phrases through various tasks.
