Transcript of Open Learning Analytics panel presentation - LAK 15
OAAI: Overview and ImpactEDUCAUSE Next Generation Learning
Challenges (NGLC)
Funded by Bill and Melinda Gates Foundations
$250,000 over a 15 month period
Goal: Leverage Big Data concepts to create an
open-source academic early alert system and
research “scaling factors”
Student Aptitude Data (SATs, current GPA, etc.)
Student Demographic Data (Age, gender, etc.)
Sakai Event Log Data

OAAI Early Alert System Overview
Intervention Deployed“Awareness” or Online
Academic Support Environment (OASE)
“Creating an Open Academic Early Alert System”
Model DevelopedUsing Historical Data
Step #1: Developed model using historical data
Academic Alert Report (AAR)
Research DesignDeployed OAAI system to 2200 students across four institutions• Two Community Colleges
• Two Historically Black Colleges and Universities
Design > One instructor teaching 3 sections• One section was control, other 2 were treatment groups
Each instructor received an AAR three times during the semester:• Intervals were 25%, 50% and 75% into the semester
Fall ’12 Portability FindingsConclusion
1. Predictive models are more
“portable” then anticipated.
2. It is possible to create generic
models that are then “tuned” for
use at specific types of
institutions.
3. It is possible to create a library of
open predictive models that
could be shared globally.
Intervention Research Findings Final Course Grades
Analysis showed a statistically significant
positive impact on final course grades
• No difference between treatment groups
Saw larger impact in spring then fall

Instructor Feedback
"Not only did this project directly assist my students by guiding students to resources to help them succeed, but as an instructor, it changed my pedagogy; I became more vigilant about reaching out to individual students and providing them with outlets to master necessary skills.
P.S. I have to say that this semester, I received the highest volume of unsolicited positive feedback from students, who reported that they felt I provided them exceptional individual attention!

More Research Findings…
Intersections between openness and Learning AnalyticsOpen Source Learning Analytics Software• Weka, Kettle, Pentaho, R, Python etc.
Open Standards and APIs for Learning Analytics• Experience API, IMS Caliper/Sensor API
Open Models - Predictive models, knowledge maps, PMML etc.
Open Content/Access – Journals, whitepapers, policies documents
Openness or Transparency with regards to Ethics/Privacy
NOT anti-commercial – Commercial ecosystems help sustain OSS
Software Silos vs. PlatformsMany learning analytics solutions today are“tool” or “software-centric”• Analytics tools are built into existing software such as the
Learning Management System (LMS)
Can make it harder to capture data and integrate across systems (limits Big Data)
A platform solution would allow institutions to collect data from across many systems• A “modularized platform” approach allows institutions to use all or just some components
• Integration points allow data to “flow” in for processing and results to flow out
Apereo Learning Analytics Initiative (LAI)Goal: Operationalize outcomes from Learning Analytics research as means to develop, maintain and sustain an open platform for Learning Analytics
Current Proof-of-Concept Projects◦ University of Amsterdam – Larrisa (open-source Learning Record Store)
◦ Marist College – Learning Analytics Processor (LAP)
◦ Uniformed Services University – OpenDashboard
◦ Sinclair Community College – Student Success Plan
◦ Unicon – OpenLRS and commercial support services

Strategic Vision: Open Learning Analytics Platform
Collection – Standards-
based data capture from any potential source using Experience API and/or IMS Caliper/Senor API
Storage – Single repository
for all learning-related data using Learning Record Store (LRS) standard.
Analysis – Flexible Learning
Analytics Processor (LAP) that can handle data mining, data processing (ETL), predictive model scoring and reporting.
Communication –
Dashboard technology for displaying LAP output.
Action – LAP output can be fed
into other systems to trigger alerts, etc.
Library of Open Models
Learning Record Store & Data Collection• OpenLRS is a secure, standards-based,
standalone Learning Record Store built to fill the need for a high i/o storage mechanism for an open learning analytics environment
• Technical Stack• Spring-Boot
• Pluggable Datastores (redis, elasticsearch, mongodb)
• xAPI integrations to get activity streams
• Roadmap• Integration & Support for IMS Caliper

Student Success Plan
• Case Management Software
• Academic Advising Tools (MAP)
• Early Alert / Faculty Access (EAL)
• Student Interface (Tasks, MAP, Self
Help)
• Student Information System (SIS)
Integration
• Reporting Tools / Data Collection
Open Dashboard
• Web application that provides a framework
for displaying analytics visualizations and
data views called “cards”.
• Cards represent a single discrete
visualization or data view but share an API
and data model
• LTI compliant
• Widget(Card) library for Learning Analytics

Early Alert Insights ChartCourse Engagement Pathways – Resource & Content Access
Demo Overview• Three core components of a collection of
open source applications and services that
represent the “Analytics Diamond”
• Can be used individually or collectively
• Work with a shared infrastructure and data
model
Technologies:• AngularJS
• Spring-Boot
• Pluggable Datastores
(redis, elasticsearch, mongodb)
