The Introductory Accounting data set, like the College Algebra data set, is a collection of extremely fine-grained learning outcomes (that we call Micro-outcomes) mapped into a graph model with prerequisite relationships between Micro-outcomes.
In addition to Micro-outcomes, the data set also contains equally fine-grained Assessments (that we call Micro-Assessments). Every Micro-outcome has at least one corresponding Micro-Assessment, usually more.
This data set was created as part of the Fly-by-Wire project. To learn more about the modeling and mapping of this data, read our paper on mapping fine-grained outcomes and assessments with network models.
To help you visualize the entire data set, we used Rhumbl, an external tool for network mapping to create a network visualization.

The model structure of this data set is identical to that of the College Algebra collection. In this data set, we have three types of entities and two types of relationships:
Micro-outcomes are connected to each other via the presence of has-prerequisite-of relationships. Micro-outcomes are grouped under Modules via the presence of has-parent-of relationships. The curriculum model diagram looks like:
We also have Micro-Assessments, which are assessments that are of incredibly fine-grained resolution such that every Micro-outcome can be linked 1:1 to a corresponding Micro-Assessment. A Micro-Assessment looks like:
Every Micro-Assessment has a selection of answer choices with one correct choice; for example, answer choices B, C, and D are incorrect in the above example. Each answer choice is linked to a Micro-outcome — this linkage demonstrates the notion that the reason a learner may pick this given answer choice is due to insufficient competency in its linked Micro-outcome.
Authoring the Micro-outcomes and Micro-Assessments, as well as linking them together, was a herculean task undertaken by subject matter experts and instructors as part of the Fly-by-Wire project.
The data set has been implemented in the frontend applications of the FbW Student and FbW Instructor appications. Micro-outcomes and Micro-Assessments were tested and revised for a period of four years on hundreds of students at community colleges.
