Vermont Mathematics Partnership Ongoing Assessment Project (OGAP)
OGAP was developed as a part of the Vermont Mathematics Partnership funded by a grant provided by the US Department of Education (Award Number S366A020002) and the National Science Foundation (Award Number EHR-0227057)

OGAP is an intentional and systematic FORMATIVE Assessment approach to gathering and interpreting evidence on student learning in mathematics – as students learn.
OGAP materials are aligned to national mathematics expectations (PSSM) and NCTM Focal Points, respond to elements of the National Mathematics 2008 Panel Report, and has a design based on research of how students develop understanding of concepts, common errors that students make, and misconceptions/preconceptions that students may have.
OGAP materials, resources, and professional development are available for fractions, multiplicative reasoning, and proportionality.
The OGAP system involves:
1) gathering information about pre-existing knowledge through the use of a pre-assessment;
2) analyzing the evidence in student work from the pre-assessment to guide unit planning; and
3) a continuous and intentional system of probing with OGAP questions during an instructional lesson/unit, analyzing evidence in student work, and making instructional modfications as students are learning.
The OGAP Formative Assessment System is supported by:
1) Pre-assessments that consist of short constructed response questions designed to elicit developing understandings, common errors, and pre-conceptions or misconceptions that may interfere with students learning new concepts or solving problems;
6) Instructional strategies teachers used in response to evidence in student work based on our work with over 300 educators who use OGAP materials in their classroom;
7) Materials and activities to communicate research (sample page from PD materials);
8) Professional development to support use and implementation of OGAP.
