Abstract : In this paper, we establish an asymptotic formula for mean value of $L^{(k)}(\frac{1}{2},\chi_{P})$ averaging over $\mathbb P_{2g+1}$ and over $\mathbb P_{2g+2}$ as $g\to\infty$ in odd characteristic.
We also give an asymptotic formula for mean value of $L^{(k)}(\frac{1}{2},\chi_{u})$ averaging over $\mathcal I_{g+1}$ and over $\mathcal F_{g+1}$ as $g\to\infty$ in even characteristic.
Keywords : function fields, derivatives of $L$-functions, moments of $L$-functions, quadratic Dirichlet $L$-functions
