  One of the primary goals of the RHIC spin program is to determine the
spin-dependent gluon distribution, $\Delta g(x)$, of the proton. The
measurements of the 2009 longitudinal double-helicity asymmetry, $A_{LL}$, for
mid-rapidity inclusive jet and $\pi^{0}$ production place strong constraints on
$\Delta g(x)$ and, for the first time, find evidence for non-zero gluon
polarization values for partonic momentum fraction $x$ greater than 0.05. In
contrast to inclusive jets, dijet correlation measurements provide access to
partonic kinematics at leading order, and thus give better constraints on the
behavior of $\Delta g(x)$ as a function of gluon momentum fraction.
Furthermore, dijet measurements at higher rapidity probe the lower $x$ values
where $\Delta G$ is poorly constrained.\\ In these proceedings, we present the
first measurement of $A_{LL}$ for dijets with at least one jet reconstructed
within the pseudorapidity range 0.8 $< \eta <$ 1.8 at STAR. The dijets were
measured in polarized proton+proton collisions at a center-of-mass energy
$\sqrt{s}$ = 200 GeV. Values of $A_{LL}$ are determined for several distinct
event topologies, defined by the jet pseudorapidities, and span a range of
parton momentum fraction $x$ down to $x \sim 0.01$. The measured asymmetries
are found to be consistent with the predictions of global analyses that
incorporate the results of previous RHIC measurements. They will provide new
constraints on $\Delta g(x)$ in this poorly constrained region when included in
future global analyses.
