The 18-year-old midfielder agrees with manager David Moyes that his spell at Hillsborough improved his overall game after returning to Goodison Park earlier this week
The 18-year-old midfielder made 13 appearances during his time at Hillsborough, scoring four goals.
Following his return at Goodison Park earlier this week, Toffees manager David Moyes said he felt regular first-team football had benefited the youngster.
"I enjoyed it," Barkley told the club's official website. "I was there for two months and it was valuable experience, which I needed because playing in the Under-21s, it's good, but you need to be playing competitive football for points.
"It helped. By going away I feel like I've turned into a better player. I've learned quite a lot in a short space of time.
"The players talk more because they're fighting for points and we were low in the league and trying to get up. Also with the Under-21s, it's not really as physical as it is in the Championship, and it's much better playing in front of crowds too."
Keen to keep tabs on Barkley's progress, Moyes sent a member of his backroom staff to report back on the youngster every time he appeared for the Owls, while also watching two of his performances in person.
Barkley added: "It was nice to know he [Moyes] was watching. It shows he wants to know how I'm getting on, how I'm progressing and how I'm learning.
"Now I just want to make an impression. I believe I'm better prepared now, more consistent.
"The manager's just said to do what I'm doing in training, do what I'm doing in matches and be ready to take my chance."
