Using visuals is a well-known strategy
to teach emergent bilinguals (EBs). This study examined how preservice teachers
(PSTs) implemented visuals to help EBs understand mathematical problems and how
an innovative intervention cultivated PSTs’ capability of using visuals for
EBs. Four middle school mathematics PSTs were engaged in a field experience with
EBs to work on mathematical problems; during the field experience, the PSTs
received interventions. In one intervention session, the PSTs were asked to
make sense of a word problem written in an unknown language with different
visuals. After this intervention, they changed their use of visuals when
modifying tasks for EBs. The results suggest that immersive experiences where
PSTs can experience learning from the perspective of EBs helps PSTs implement
mathematically meaningful visuals in a way that makes mathematical problems
accessible to EBs.

One goal in teacher education is to prepare
prospective teachers (PTs) for a career of systematic reflection and learning
from their own teaching. One important skill involved in systematic reflection,
which has received little research attention, is linking teaching actions with
their outcomes on student learning; such links have been termed hypotheses. We
developed an assessment task to investigate PTs’ ability to create such
hypotheses, prior to instruction. PTs (N = 16) each read a mathematics lesson
transcript and then responded to four question prompts. The four prompts were
designed to vary along research-based criteria to examine whether different
contexts influenced PTs’ enactment of their hypothesizing skills. Results
suggest that the assessment did capture PTs’ hypothesizing ability and that
there is room for teacher educators to help PTs develop better hypothesis
skills. Additional analysis of the assessment task showed that the type of
question prompt used had only minimal effect on PTs’ responses.
