Participants in this study were selected from the population of the sixth grades students who were learning English as a foreign language (EFL) in three English Language institutions in Rezvanshahr city, Iran during the winter semester of 2022. Six grade students were only male, their age level were ranged from twelve to thirteen years old. 100 elementary level of six grade students were chosen from 120 six grade students of Iran who were learning English as a foreign language (EFL) in three English Language institutions in Rezvanshahr City, Iran based on their scores on the Oxford Quick Placement Test (OQPT) (See Appendix A) and all students had participated in the Oxford placement test prior to the onset of the course, and their scores ranged from a total band score of 0 to 25 which is correspondent to the A1 elementary level according to the interpreting scores of Oxford placement test (See Table 3.2).

It is worth noting that all the sample population in this research were sixth grade male students who were in the same socio-economic status, geographical area and socio-cultural level in the Rezvanshahr city of Guilan province in the winter semester of the 2022-2023 academic year. After homogenizing, some of the population was dropped out from the study. The researcher then randomly divided the participants into two intact groups, an experimental group and a control group, each consisting of 50 six graders.
