  1. Program ReviewSupport Tool Nathan Pellegrin Research Analyst

  2. Goals • Background and purpose of the tool • Demonstration • Cal-PASS update • OLAP Development at Cal-PASS • OLAP Success Story: SSPIRE Cube • Future development

  3. The Program Review Support Tool • Funded by Hewlett. • Currently being tested by several colleges. • All data is from MIS. • Caveat: figures may not match what is found in locally produced reports due to differences in master data sources and formulae used to derive figures. • Like a “data smorgasbord” and includes • student demographics • course grades • TOP code course hierarchy … the menu will be expanding !

  4. Purpose • Not the product of a mandate or requirement from the Chancellors office. • Not intended to take the place of local tools. • Not intended to drive evaluation activities. • Intended for use by colleges as an optional FREE tool in their program review process. • Obtain feedback from users to scale and improve our data model and OLAP infrastructure.

  5. Cal-PASS Statistics • Over 300,000,000 records • Up to 15 years of data in some regions • Over 7,000 schools, colleges and university members • Over 150 research studies conducted in the last two years • Sixty-six Professional Learning Councils (1,200+ faculty)

  6. Universities (23) • UC . • Davis • Merced • Riverside • San Diego • Santa Barbara • Santa Cruz • CSU . • Channel Islands • Dominguez Hills • Fresno • Long Beach • Los Angeles • Monterey Bay • Pomona • Sacramento • San Bernardino • San Marcos • Stanislaus • San Francisco • San Jose • Sonoma • PRIVATE . • Otis College of Art and Design • National University • University of the Pacific

  7. Changing the Paradigm:OLAP Applications • OLAP = On-Line Analytical Processing • Like Excel pivot tables, except Excel handles only two dimensional data. • Stores pre-computed aggregations of data with B-Tree indexing for delivering fast retrieval times and fast calculation. • Enables users to perform analysis of data quickly with drag-and-drop manipulation of variables and dynamic visualization. • Web-based for easy access – all processing is performed on the server so it does not tie up your work station (zero footprint). • Big time savings! • Ideal for the action research paradigm and design research.

  8. 3 Layers of the Application User Interface - Dundas MDX OLAP Cube - SSAS SQL Database(s) – SQL Server

  9. Development Process of the OLAP project is a technical collaboration between IT and Research … • Server Architecture/O.R. – Alex Zakharenkov (IT) • Submission Processes/User Interface – Nick Wade (IT) • Data Model/ETL – Nathan Pellegrin (Research) • Design/Feedback of OLAP cubes - All IT and Research Staff, including Terrence Willett and Mary Kay Patton

  10. Development times • Development of initial Dim Model started in July 2008 … incremental additions/changes congealed into a (basic) model by February, 2009. • Initial development of Program Review, including feedback and changes ≈ 8 weeks. • Dim model ETL execution ≈ 15 hours. • Processing of OLAP cube ≈ 20 min./300K rows . • Initial deployment of UI ≈ 3 weeks. Several changes since then. • UI required tweaks to OLAP cube design.

  11. Development Tools • .NET • SQL Server • storage • Integration Services • Analysis Services • BIDS • Dundas

  12.

  13. What does a dimensional data model do for Cal-PASS? UNIFY: Data from across segments is integrated into a unified dataset. STANDARDIZE: Table and field names, data types and value coding systems are standardized to be the same for all segments. SIMPLIFY:The number of tables and fields used to store the data is reduced. Granularity of tables are at the units of analysis. Table relationships reflect analytical relationships between entities. IMPROVE DATA QUALITY: Merging data brings data quality issues to light so they can be noted and/or resolved. Establishing primary and foreign key relationships enforces referential integrity. Multiple student identifiers are unified to produce a single “metakey” Missing course CBEDS classifications imputed using machine learning. REDUCE RISK: Without it, in order to produce one metric for all segments separate analytical data processing pathways are required for each segment, which means more maintenance and increased risk of inconsistent results. Using a dimensional model the analytical computations and services are centralized. BOOST PRODUCTIVITY: The simpler, cleaner data model makes it easier to develop cubes with re-usable components, generalized for all segments. Currently, analytical data processing must be developed separately for each segment. Using a dimensional model, only one pathway needs to be developed that applies to all segments.

  14. Cal-PASS Unified Dimensional Data Model (Selected Tables) Organization Student Status Student Course Outcome Course Course Taxonomy Award = Fact Table = Dimension Table Term = Foreign Key Relationship

  15. The Ideal: Centralization of analytical query processing Each statistic can emerge at multiple presentation points, but there is only one logical control point. Presentation & User Engagement OLAP Views and Stored Proc’s Dimensional Model Tables User-defined cohorts; model outputs

  16. Student identifiers from each source system are mapped to a new identifier through transitive closure of all connected values (using a modified version of the Floyd–Warshall algorithm). Name + gender + DOB Local district student id CCCCO SID (SB00) CSIS SSID n1 d1 o1 n2 m1 c1 d2 d3 Each edge represents a record linking two values of different identifiers in submitted student records.

  17. OLAP Success Story: SSPIRE Cube • Funded by Irvine Foundation. • Currently used by nine colleges. • Incorporates MIS data with data submitted by colleges (custom files). • Tracks cohorts of students. • Demonstrate using Merced college (thank you Dr. Duran!)

  19. This is only the beginning… Provide access to K-12 districts and Universities Inter-segmental OLAP Cubes Link non-academic outcomes (Employment Development Department, Child Welfare Data System) “Success at Every Level”

  20. Education Data and Information Act of 2008SB 1298 1. convene a high-level working group to decide the best the governance structure for the comprehensive education data system; 2. directs the State Chief Information Office (CIO), in consultation with educators and education policymakers, to prepare a strategy plan outlining a clear path for technical implementation; and3. requires the various education segments to begin using a common student identifier, so that once a governance structure and technical architecture are in place we can begin linking records from pre-k through the university with relative ease and speed.
