CHAPTER IV 
DISCUSSION OF THE RESULTS 
4.1 The intervention results
4.1.1 Pre-testing results 
The sample and the control groups were exposed to oral pre-
testing at the beginning of the intervention before any specific practice 
was applied. The objective of the pre-testing was to identify each 
participant’s pronunciation proficiency level with regard to Case 1, Case 
3, Case 5, Case 6, Case 7, Case 8, and Case 9 of phonological 
interference, and to deduce the average score in each group. Moreover, 
pre-testing allowed for obtaining the results of the average score of each 
problem case individually.

Graph № 3. Average score of each problem case in Sample group. 
Graph 2 shows the results of the pre-testing of each participant in 
the sample group. A scale based on 0 to 20 points has been used. The 
scores range from the lowest point 6 (Student 13) to the highest point 17 
(Student 17). The pre-testing average score in the sample group is 11.82 
points. It comprises the seven cases of phonological interference 
altogether.
Graph 3 demonstrates the average score obtained in the sample 
group in regard to each case of phonological interference individually. A 
scale based on 0 to 10 points (as per the oral test) has been used. As the 
graph presents, Case 9 has the highest score of 7.41 points, therefore, the
