The Strathaven star is the only female player ever to captain their country at such a prestigious event, but Aileen oversaw a disappointing championships for the Scots as they finished eighth out of the 10 teams taking part.
Russia were the eventual winners with a thumping 9-1 win over hosts South Korea in Sunday’s final.
But the tournament marked one of Scotland’s worst-ever finishes at a World Championships.
And Aileen – who skipped Scotland to world silver at last year’s event in the Czech Republic – says the arrival of new coach Tony Zummack saw the Scots try some different tactics to previous years.
But she insisted their six defeats from nine round-robin matches were down to the squad’s lack of killer instinct.
Aileen told the News: “Obviously, the whole team are disappointed with the result because we didn’t play the way we would have liked.
“One of the reasons for this is we’ve got a new coach and he has been trying some different tactics with us which, although they didn’t work last week, will make us better curlers in the long run.
“You can’t make lots of changes and expect everything to click overnight, but the fact we beat Russia in the round robin, shows what we are capable of when everything comes together.
“For us it will be about finding consistency and that will come.
“But, ultimately, when it came down to it, we didn’t make the big shots when it mattered.”
Scotland opened their campaign last Sunday with a 6-5 defeat at the hands of China, but Aileen’s team responded with an 8-6 win over Norway in the afternoon.
Monday saw the Scots come out fighting as they thumped eventual winners Russia 4-1, but that was quickly forgotten as they slumped to an 8-2 loss to Canada.
And the defeats kept on coming as a 6-4 loss to USA, a 9-2 humbling by Korea, a narrow 5-4 defeat to Slovakia and a final day 8-4 beating by Sweden sandwiched their only other win of the campaign, a 10-0 triumph over Italy.
Despite the disappointment of South Korea, Aileen still enjoyed her time in the country and is looking forward to working on next year’s competition in Sochi, Russia, where the 2014 Winter Paralympics will be held.
Aileen added: “South Korea were fantastic hosts. We had great transport and they made all the facilities very accessible for us.
“The food was a bit different, but we still managed to try some things and enjoy ourselves.
“It’s Russia next year for the World Championships so for now we go back and have a look at the videos and see what we did well and what we didn’t do so well, so we can build on this year’s experience and develop our tactical awareness over the coming months.”
