The 52-year-old was jeered on entering his technical area during Saturday's 3-0 home victory over Cardiff, a result which ended a run of six successive defeats.
However, he is refusing to allow the pressure to get to him as he prepares for Sunday's final-day trip to Liverpool.
Pardew told the Shields Gazette: "Obviously, I'm a little bit sad about the situation, but my resolve has to be strong to make sure the players are ready for Liverpool. We need to go to Anfield and put in a top performance."
Pardew, who signed an eight-year contract in September 2012, is not understood to be in any immediate danger of losing his job, although he will have to negotiate his end-of-season debrief with owner Mike Ashley.
The Londoner kept his job after narrowly surviving relegation 12 months ago but this time around, the Magpies will finish no lower than 10th.
Should Pardew receive the green light from Ashley, he will hope to embark upon a major rebuilding exercise this summer with strikers Loic Remy and Luuk de Jong only on loan and Shola Ameobi out of contract.
A replacement for big-money January departure Yohan Cabaye, to Paris Saint-Germain, will also be high on his priority list.
Pardew said: "We need to make sure we start next season in the same position we started this season. We had a strong team and were challenging for Europe.
"But towards the back end of the season, we have not been that good. We need to accept that, accept the criticism and make the right calls."
