Frequent implementation of these practices was found to be positively associated with learning outcomes in high- and medium-achieving countries but negatively associated with learning outcomes in low-achieving countries.
The frequent implementation of more student-centered modes was found to be positively associated with learning outcomes in high- and medium-achieving countries, but negatively associated in low-achieving countries.
The main reason for non-participation was the frequent implementation of different governmental programs which interrupt the education schedule.
