Pardew handed James Tavernier, Shane Ferguson, Mehdi Abeid, Gael Bigirimana, Sammy Ameobi and Nile Ranger starts in Bordeaux, but saw several of them struggle to make their mark as the French side secured a comfortable 2-0 Europa League victory to clinch top spot in Group D.
Pardew admitted he had expected to see more from his new generation and revealed they could be sent away from Tyneside to further their education, depending on injuries and the club's activity in the January transfer window.
He said: "When this (Europa League) comes around in February, I am hoping to have a stronger position in the Premier League and to have a stronger squad to pick from, certainly stronger than I had tonight.
"A few of those young players, like Nile Ranger....he has only had one reserve game and that was a bit tough on him. But we felt he deserved the right to play a game and he has trained well.
"But certainly looking at my group there, I think they need to learn a little bit more about this game away from the black and white and the pressure of the jersey here and the level we are playing at.
"I will probably look at loaning a few of those who played tonight, hopefully after January when I have got a stronger position in the squad."
Goalkeeper Rob Elliot was one of the few men to distinguish himself at the Stade Chaban-Delmas as he made fine saves to deny Henri Saivet, Fahid Ben Khalfallah and David Bellion.
But even he could not keep Bordeaux at bay with 29 minutes gone when Mali international striker Cheick Diabate climbed high above James Perch to head Ben Khalfallah's cross home.
Newcastle briefly threatened to drag themselves back into the game after the restart, but Diabate's second 18 minutes from time ensured there was no fightback.
Pardew said: "The pitch was difficult. They play rugby on that pitch and it was heavy on the legs.
"I thought they coped better with the pitch and they were the better side and they deserved to win."
Pardew was at least able to comfort himself with positive injury news from home as he turned his attention to Monday night's Barclays Premier League trip to Fulham.
He could have Davide Santon, Cheick Tiote, Jonas Gutierrez, Hatem Ben Arfa, Gabriel Obertan and Demba Ba back for the game at Craven Cottage, and that would be a massive boost as he attempts to build on last Monday's 3-0 win over Wigan.
Pardew said: "The news I am getting from back home is that Cheick, Demba, Obertan and Hatem will train tomorrow, and we hope that Jonas can train on Sunday and Davide Santon too, and we will be in a lot better position for that game."
