I highly doubt it.

He worked for the Mis-use of Muggle Artifacts Office at the Ministry. I’m aware that they prioritized enthusiasm and a tolerant attitude above all. However, it is likely that he had 5 years of Muggle Studies under his belt before working there, with at least an Exceeds Expectations grade at OWL Level.

Upon meeting Harry Potter he asks him “what exactly is the function of a rubber duck?” It’s a ridiculious question, considering that wizards probably had inflatable bath toys too. So why ask it?

Mr. Weasley has just arrived in from work and laid eyes on Harry, a troubled boy and his son’s best friend. Upon greeting the boy, he realizes notes that all the attention is making him uncomfortable. He deduces he is staying with them because his home situation has deteriorated.

He takes all of this in his stride and asks a question he knows will make the Boy Who Lived laugh. Afterwards, he asks him countless questions about electricity etc. Of course, he has a real desire to learn how airplanes stay up. After all, aerodynamics are complicated.

Arthur is a man who has raised seven children. He is no doubt employed the tactic that many parents use with young kids; asking rhetorical questions and/or playing dumb so that they can gain confidence and enjoy sharing their knowledge.

More advanced tactics are seen throughout the later books. In Goblet of Fire, Arthur pretends to be struggling to light the fire and pitch the tent. Hermione stays with him to help. This is good, because it allows Arthur to keep up a running commentary on Ministry officials that pass by.

In Order of the Phoenix, Arthur Weasley pretends to be struggling to use the underground and make change with Muggle currency. By asking Harry for assistance with these small tasks, he is providing a much-needed distraction in the run up to the hearing.

He does all this without drawing attention to himself. His first priority is to help the children in his care feel more comfortable.
