By what process did the Muslim Empire receive and exchange their ideas, achievements, and knowledge?
We can say that the Muslim Empire received and exchanged those things through trade and conquest. But basically through trade.
Islam spread in the 13th century.
In the beginning, Islam was introduced through Arab Muslim traders and merchants. After they did so, it was the rulers through the conversion of the elite people. Missionaries came from Southern Asia, like Champa and Gujarat. There also were missionaries from the Hadhramaunt, in Arabian Peninsula.
In those years, during the Fatimid Caliphate, Muslims from Arabi expanded their territories and captured some parts of North Africa, including Egypt. Trade was a very important activity and helped spread Islam throughout many regions of Africa. Muslim traders took their Islam beliefs everywhere and influenced many people.
Answer: Grit
Explanation: What sociologist Paul Tough felt it needed to develop in children was the courage and strength of character to work steadily and persistently toward the set goals, which is grit. Grit is therefore a positive trait that needs to be developed and that implies a strong motivation to achieve goals, so it is not a cognitive trait, this is about stimulating curiosity, pinpointing and setting goals, and working hard to reach those goals. This trait should be developed in children at school from the earliest days, encouraging and directing children by evaluating their curiosity, directing them to social intelligence that is important when it comes to grit, for example, teaching children to be grateful for their accomplishment and help. There is an emphasis on work that, in combination with social interaction, constant improvement and shifting of criteria, means reaching the goal as well as setting new ones.
