Using Learner Analytics to Understand Student Achievement in

a Large Enrollment Hybrid Course

Outline1. Context

2. Learning Analytics, Methods & Tools

3. Findings

4. Conclusions & Next Steps

5. Becoming a Data Scientist (pending time & interest)

Why are you here? 1. To increase my knowledge of “Learning

Analytics”

2. To get ideas about how I can become a “Data Scientist” (or practice analytics)

3. To learn about the results of this study

4. Because this was the closest room

1. CONTEXT

Case Study: Intro to Religious Studies• Undergraduate, introductory, high demand

• Redesigned to hybrid delivery format through “academy eLearning program”

• Enrollment: 373 students (54% increase on largest section)

• Highest LMS (Vista) usage entire campus Fall 2010 (>250k hits)

• Bimodal outcomes:• 10% increase on final exam• 7% & 11% increase in DWF

• Why? Can’t tell with aggregated data

54 F’s

Guiding Questions1. How is student LMS use related to academic

achievement in a single course section?

2. How does that finding compare to the relationship of achievement with traditional student characteristic variables?

3. How are these relationships different for “at-risk” students (URM & Pell-eligible)?

4. What data sources, variables and methods are most useful to answer these questions?

2. LEARNER ANALYTICS, METHODS & TOOLS

Learner Analytics

“ ... measurement, collection, analysis and reporting of data about learners and their contexts, for purposes of understanding and optimizing learning and the environments in which it occurs.” (Siemens, 2011)

Data Extracts & Sources LMS Data

– SQL queries on WebCT Vista web server log file

Student Data– Query against Peoplesoft data– ERSS data elements (common to CSU)– Required Institutional Research

Course Data– Query against Peoplesoft data

Tools Used

App Function

Excel Early data exploration; simple sorting; tables for print/publication

Tableau Complex data summaries and explorations; complex charts; presentation chartsFinal/formal descriptive data; statistical analysis; some charts (scatterplots)Statistical analysis (factor analysis)

Methods at a Glance1. Clean/filter/transform/reduce data (70% effort)2. Descriptive / exploratory analysis (20% effort)3. Statistical analysis (10% effort)

– Factor analysis– Correlation single variables– Regression multiple variables; partial & complete

Previous Studies Relating LMS Use to Course Grade

4. CONCLUSIONS & NEXT STEPS

Conclusions1. At the course level, LMS use better predictor of

academic achievement than student demographics (what do, not who are).

2. Small strength magnitude of complete model demonstrates relevance of data, but suggests that better methods could produce stronger results.

3. LMS data requires extensive filtering to be useful; student variables need pre-screening for missing data.

More Conclusions4. LMS use frequency is a proxy for effort. Not a

very complex indicator.

5. Student demographic measures need revision for utility in Postmodern era (importance to student, more frequent sampling, etc.).

6. LMS effectiveness for at-risk students may be caused by non-technical barriers. Need additional research!
