Yes if you make them exactly half length.

Does your book have slurred staccato?

Staccato is Italian for "detached". On a piano you'd have small breaks between the notes, to taste. Certain pieces, such as Debusy's Passepied literally employ quavers. It's much easier for a writer to write staccato notes than quavers and quaver rests.

On a violin it's more complicated. Détaché means detached too - it's the opposite of legato. In the context of a slur or legato, i.e. a single bow, staccato means detached, or shorter notes. There's probably nothing to stop you from playing them any length you like. But détaché notes can also be staccato on a violin! Treat them as staccato on a piano. A lot of baroque music assumes you will play détaché notes staccato. So there's the bars over the notes to tell you to give the notes their full length.

Ok thank you both. The demos I’ve seen of staccato, the notes are all on one bow… definitely won’t be doing that for a long time but I think I can do staccato on one note.

It's not compulsory - while attempting some Schubert I was surprised to be told by my teacher that staccato wasn't necessary (in the particular place where it was indicated).

But it can be used for bow management - if you have a long downbow followed by a staccato passage followed by a long downbow, you more or less have to play the staccato passage all on the upbow. If not followed by a long downbow (as in the Schubert), you have some flexibility to choose what to do.

So now after practicing for stringy’s boat party, I’m finding stacatto slurred with a crotchet really difficult .. 

  

I just watched that video.

When only two notes are involved it's usually called hooked bowing, rather than staccato. You can look that up on youtube.

An important principle in many musical instruments is the concept of double-action. A drum kit's bass drum pedal has double action - you can press with the toes,  and you can press with the heel. This enables you to play faster - you alternate heel toe heel toe.

Strumming guitars and ukes involves arm and wrist double-actions.

It's the same with violin bowing and hooked bowing - you can down bow with the arm, and you can end with a wrist flick for the second note, then up-bow with the arm, when the wrist is already in position and doesn't have to move.
