Pardew admits that the team has not been good enough recently but wants to restore the unity that the club had earlier in the season.
"If you lose four on the trot as Newcastle manager it will always be difficult," he told reporters.
"We all have to shoulder responsibility, none more so than myself. I think the fans are fair, and we haven't been fair to them recently with our performances.
"I want to bring back that harmony we had with them not so long ago."
Newcastle's next game is against Swansea City on Saturday afternoon.
