THE IMPACT OF NEGOTIATED LESSON PLAN ON INTERMEDIATE EFL LEARNERS’ VOCABULARY KNOWLEDGE

The current study investigated the effect of the traditional lesson planning determined by teachers and the negotiated lesson plan (NLP) on Iranian intermediate EFL learners’ vocabulary knowledge. To this end, a copy of Solution Placement Test was administered to 47 learners, and 36 participants at the intermediate level of language proficiency were homogeneously selected. They were then divided into two groups of 18 participants as the experimental and the control groups. Next, the vocabulary pretest was conducted to measure the participants’ vocabulary knowledge and check the homogeneity of the groups at the beginning of the treatment. The learners in the experimental group shared their ideas in small groups, had the key role and enjoyed shared-decision making deciding what they would do for the next sessions of the course. The learners in the control group had no role in determining the course materials. The result of data analysis based on their pretest and posttest scores of vocabulary showed that the participants of the experimental group became better vocabulary learners after receiving NLP treatment compared to those in the pre-determined lesson plan that received unnoticeable results from the pretest to the posttest. The teachers and the material developers need to consider the negotiated lesson planning into account so that the issue of learner involvement in instructional materials is paid attention to.  Article visualizations:
