McDonald admits his side can not afford to slip up against the SPL strugglers, who remained at the foot of the table after their 1-0 loss to Hearts on Boxing Day.
He said: "These are the type of games we expect to be taking three points from, although I did say that before the Hamilton game and it did not work out.
"That just makes it even more important for us to start putting the points on the board and getting ourselves up there."
The 27-year-old thinks his side will have to prevent Bairns midfielder Scott Arfield from getting time and space on the ball if they are to emerge victorious.
He said: "We know they will make it difficult for us as they have some good players, particularly Arfield who I would say is their danger man.
"I think he makes them tick and a lot of Falkirk's good play goes through him."
Meanwhile, McDonald has revealed talks to extend his stay at Pittodrie are progressing well.
He added: "They are going fine. I am just letting my agent get on with it. I don't think about it at all, I just concentrate on my football. I'm happy here and enjoying my football."
Falkirk defender Marc Twaddle is hoping his side can earn a new reputation for resilience as they bid to spring off the foot of the SPL with a victory at Pittodrie.
The Bairns have been known for their attractive style but have been accused of failing to add the necessary end product to their play.
That was again in evidence on Saturday as Eddie May's outfit enjoyed the upper hand against Hearts but went down 1-0 in a game in which their opponents enjoyed just two shots on target.
However, Twaddle believes there are still positive indications that May's side can shake off old failings and transform themselves into a side capable of challenging at the other end of the division.
He said: "There's a gap starting to develop between the top four and the rest. There's no reason why we can't claw back the difference and push on from there.
"We've always managed to stay positive as a group, even when results haven't gone our way.
"We know where we want to go as a team and what it takes to get there. We want to be challenging at the top end of the table and playing the right way. That's what we're working towards every day in training.
"It's been the Falkirk way in the last few years to win plaudits for playing well without achieving anything.
"We want to shake off that image and I think there are encouraging signs that we're becoming a bit more resilient."
