This study aimed at investigating the effect of an extended teacher wait time on student participation in primary school context. The main purpose of the study was to inquire whether primary level students would participate in the lesson more when they are given extended wait time after questions than those lessons in which they received average wait time. Students&rsquo / attitudes towards receiving extended wait time and teachers&rsquo / opinions about and experiences in applying it were also explored. For this purpose, two fifth grade classes at ihsan Dogramaci Foundation Bilkent Primary School participated in the study. Pre-test and post-test results and first part of the teacher and student questionnaires provided the quantitative data of the study. The qualitative data came from the second part of the questionnaires that were given to the teachers and the students. The analysis of the quantitative data indicated that students who received extended wait time participated in the lesson more than the students who received average wait time. Analysis of the results of student questionnaire indicated that the students were aware of the positive outcomes of being allowed extended wait time. The results of the teacher questionnaire showed that although extending wait time strategy and its outcomes are known by the teachers, it is not widely used in the classrooms.
