gamma N->Delta transition form factors and threshold pi^0 photo- andelectroproduction are studied with the new version of MAID and a dynamicalmodel. By re-analyzing the recent Jlab data on p(e,e'p) pi^0 at Q^2 = 2.8 and4.0 (GeV/c)^2, we find that the hadronic helicity conservation is not yetobserved in this region of Q^2. The extracted R_{EM}, starting from a small andnegative value at the real photon point, actually exhibits a clear tendency tocross zero and change sign as Q^2 increases, while the absolute value of R_{SM}is strongly increasing. Our analysis indicates that A_{1/2} and S_{1/2}, butnot A_{3/2}, starts exhibiting the pQCD scaling behavior at about Q^2 = 2.5(GeV/c)^2. For the pi^0 photo- and electroproduction near threshold, resultsobtained within the dynamical model with the use of a meson-exchange pi N modelfor the final state interaction are in as good agreement with the data as ChPT.Comment: 9 pages, 5 figures, talk given at the NSTAR2001 Workshop, Mainz,  Germany, March 7-10, 200
