Predictive Learning Analytics (PLA)
o PLA identify students at risk + inform teacherso Mixed-effects of providing PLA to teacherso Difficulty in understanding and interpreting PLA data
and visualisationso Difficulty in identifying specific interventions o Promising outcomes (van Leeuwen et al., 2014;
McKenney and Mor, 2015) o Identification of participation problems and interventiono Development of curriculum materials
2
Aim of this study
Evaluate whether providing teachers with PLA data would empower them to identify and assist students in need for additional support
3
OU Analyse (OUA)
•OUA: Early identification of students at risk of failing•Available to tutors and student support teams •Aim: Improve retention of OU students

Research Questions
1.How did 240 tutors within 10 modules made use of OUA predictions and visualisations to help students at risk?
2.To what extent was there a positive impact on students' performance and retention when using OUA predictions?
3.Which factors explain tutors' uses of OUA?
8
Methodology
1.Statistical comparisons: 240 tutors OUA access Vs 613 tutors with no access to OUA predictions formal withdrawal rates by the end of the
module, completion and pass rates.
2.Usage data of OUA dashboard (N=70)3.Qualitative data: Semi-structured interviews
(N=6)

Results: Usage of OUA dashboard

Results: Interviews (1/2)Actual uses of OUA: •Most useful OUA features:
o colour-coded students o VLE activity
•Teachers define what features to use and how often (time management)
Usefulness of OUA•Teachers checking on students often (emails, forums)•Teachers more proactive/enhance teaching practices
o “on top” of studentso “where I need to put my e orts" ff
• Predictions: complement teachers’ intuition + additional insights
13
Results: Interviews (2/2)
Approaching students at risko Varied interventions - referral to student support
services, sending emails, texting, calling, doing nothing
o Varied approaches: persistent VS less pro-activeo Personalised approach
Future intentionso Interested in future use yet with improvements to
the system (e.g., “sensitive” to students’ activities online)
14
Conclusions
o Blurred picture (withdrawal, completion and pass rates)
o Variation in teachers’ degree and quality of engagement with learning analytics.
o Lack of consensus about intervention strategieso Predictive data - enhance and facilitate teaching
practice, especially within distance learning contexts
o Research directions: Identify how, when, and what interventions to trigger to support students adequately
