Adopting CDIO method on English language teaching

This experimental study is an attempt to bring a new perspective and a new teaching method CDIO (Conceiving, Designing, Implementing and Operating) to the ELT field. The CDIO method was applied on the 11th grade in a private high school in Diyarbakir, Turkey. The total number of the participants in this experimental research is 120 students, 60 in the experimental group and 60 in the control group. The students were subjected to a pretest before the treatment process and to a posttest after the process. The treatment procedures and materials were prepared according to the CDIO curriculum and standards. The treatment process lasted for fifteen weeks for the experimental group while the control group continued learning English without being exposed to CDIO teaching method. Subsequently the collected data was analyzed with the assistance of IBM SPSS Statistics 23.0 to see whether the CDIO methodology has effective results on the students' performance or not. After the data was collected and analyzed, the results showed that the students performed better after learning English using CDIO in the rate of 14.45%, where the mean score of the pretest was 71.66 while the mean score of the posttest was 86.23. Moreover, the results exhibit that the participants' fulfillment developed in grammar in a rate of 4.60% where it was 29.80% in the pretest and it increased to 34.20% in the posttest. Similarly, the participants' achievement developed in vocabulary in a rate of 4.20% where it was 32.00% in the pretest and it increased to 36.20% in the posttest. On an equal footing, the participants' performance raised in a rate of 5.73% where it was 10.06% in the pretest and it promoted to 15.80% in the posttest. Accordingly, there is a great improvement in the students' performance of the experimental group. Also, the outcomes show that the CDIO has played a big role in developing the students' level and has showed a positive effect in learning English. It is expected from this research to open the door for schools and faculties of teaching English to adopt the CDIO approach and apply it in their programs. Besides, it is expected from this research to be the start whistle for the Turkish schools and universities to adopt this new method for teaching English and cultivate the outcomes of it. Key words: CDIO method, CDIO standards, grammar, vocabulary and reading skills, experimental research.
