The moderate indication was a correct solution to Cupcake Task B (involving operating on the results of a unit coordination) without showing any work to support the unit coordination needed to enumerate the hidden cupcakes.
Most of the related research on unit coordination relies on time-intensive clinical interviews and teaching experiments.
The other two involved incorrectly solving tasks that were meant to require operating on the results of a unit coordination.
Based on the baseband pool, China Mobile Research Institute proposed C-RAN featuring a centralized base band unit, coordination, and cloud computing [6].
However, as Steffe (1992) explains, students with the first multiplicative concept cannot reinterpret the situation in terms of the results of their multiplicative unit coordination.
So far, they have focused on particular contexts for unit coordination such as fractions (Norton & Wilkins, 2009, 2010, 2013; Wilkins & Norton, 2011) or whole number length problems (Norton, Boyce, Phillips, Anwyll, Ulrich, & Wilkins, 2015).
Students' performance on decontextualized bar tasks involving continuous quantities was found to be consistent with students' level of unit coordination based on written work providing evidence for the validity of stage categorizations.
The second research question tests the association between a category of items that have increasingly been used in written assessments of unit coordination and items that the researchers had previously utilized in clinical interviews and teaching experiments.
These tasks are not dissimilar to those used by other researchers to study unit coordination (Kosko & Singh, in press; Norton, Boyce, Phillips, Anwyll, Ulrich, & Wilkins, 2015; Norton, Boyce, Ulrich, & Phillips, 2015), but they are different enough that we did not feel comfortable using them to categorize students according to the stages of unit construction and coordination.

3) strengthen unit coordination among its Standards Bureau, Social Technology Bureau, and the Monitoring and Evaluation division.
