.To your question "is it good method?" I would say there are different "schools", different ideals of how to work repertoire, bowing and holding. The European and Russian schools being the biggest.
Mathieu Crickboom was a great violinist who played with for example Pablo Casals.
His books are good. More important is the guidance you have of your teacher thru them.
I would say other famous violin methods/teaching books are
Mazas, ammong others, Some are more "hardcore" technique, others are more melodie &/or harmony focused, and of course (even not being a "method")
Bach's Sonatas & Partittas is a very important book to develop in playing, intonation and doubble stops.
Mathieu's book is good. If you want hardcore go to
Schradiek , if you like more melody/harmony studies with technique inside take
