We present precision measurements of the target and beam-target spinasymmetries from neutral pion electroproduction in deep-inelastic scattering(DIS) using the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab. Wescattered 6-GeV, longitudinally polarized electrons off longitudinallypolarized protons in a cryogenic $^{14}$NH$_3$ target, and extracted double andsingle target spin asymmetries for $ep\rightarrow e^\prime\pi^0X$ inmultidimensional bins in four-momentum transfer ($1.0<Q^2<3.2$ GeV$^2$),Bjorken-$x$ ($0.12<x<0.48$), hadron energy fraction ($0.4<z<0.7$), transversepion momentum ($0<P_T<1.0$ GeV), and azimuthal angle $\phi_h$ between thelepton scattering and hadron production planes. We extracted asymmetries as afunction of both $x$ and $P_T$, which provide access to transverse-momentumdistributions of longitudinally polarized quarks. The double spin asymmetriesdepend weakly on $P_T$. The $\sin 2\phi_h$ moments are zero withinuncertainties, which is consistent with the expected suppression of the Collinsfragmentation function. The observed $\sin\phi_h$ moments suggest that quarkgluon correlations are significant at large $x$.
