  Based on the effective dynamics in the $\bar \mu$ scheme of the spherical
symmetry reduced model in the reduced phase space formulation of loop quantum
gravity (LQG), we investigate the gravitational collapse of a homogeneous dust
cloud, with Gaussian dust serving as both the reference field and the source of
the gravitational collapse. The effective dynamics from the considered model
for a homogeneous dust cloud reduces precisely to the effective dynamics of
loop quantum cosmology (LQC) with extrinsic curvature based K-quantization,
indicating that the LQC effective dynamics lives as a subsector of the model
presented here. In both the marginally bound and the bound cases of the
collapse in effective dynamics, the singularity is resolved and replaced by a
bounce. Though quantum geometric modification from spatial curvature is not
directly included in the K-quantization it does affect the qualitative dynamics
of the collapsing dust cloud in the sense that on the one hand for the
marginally bound case, the dust cloud bounces once at fixed maximum energy
density and on the other hand for the bound case, the dust cloud undergoes
infinite cycles of contraction and expansion at energy densities dependent on
the dust mass. Finally, the mass threshold for the formation of a trapped
surface in each case is found and the matching conditions between the interior
collapsing spacetime and an effective exterior static solution are discussed.
