2. Predictive Learning Analytics (PLA)
o PLA identify students at risk + inform teachers
o Mixed-effects of providing PLA to teachers
o Difficulty in understanding and interpreting PLA data
and visualisations
o Difficulty in identifying specific interventions
o Promising outcomes (van Leeuwen et al., 2014;
McKenney and Mor, 2015)
o Identification of participation problems and intervention
o Development of curriculum materials
2
3. 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
4. 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

7. OUA Dashboard: Student view
Nearest neighbours, Predictions with real scores, Personalised recommender

8. 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
9. 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)

13. 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 students
o “where I need to put my efforts"
• Predictions: complement teachers’ intuition + additional
insights
13
14. Results: Interviews (2/2)
Approaching students at risk
o Varied interventions - referral to student support
services, sending emails, texting, calling, doing
nothing
o Varied approaches: persistent VS less pro-active
o Personalised approach
Future intentions
o Interested in future use yet with improvements to
the system (e.g., “sensitive” to students’ activities
online)
14
15. 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 strategies
o 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

-----even when module teams were able to unpack the underlying PLA results, most teachers found it difficult to identify specific interventions
van Leeuwen et al. (2014) found that teachers who received learning analytics visualisation of collaboration activities were better able to identify participation problems, and intervened more often in “problematic” groups relative to the control group of teachers who did not receive learning analytics visualisations. In a four year study of fine-grained data collection amongst 34 teachers, McKenney and Mor (2015)indicated that by engaging with learning analytics software, teachers’ professional development was enhanced (they learn from the process) and were able to develop better curriculum materials.

613 - did not have access to OUA.
17,033 students were enrolled in 10 modules - of which 4320 were supported by ALs who had access to the OUA predictions.
70 teachers received a weekly reminder (email) notifying them that the OUA predictions were available through the dashboard
170 received the OUA weekly predictions via email in excel sheets.
Model that will be rolled out across the University
Mixed outcomes: all 3 significant: In the case of the Technology (X² (1, N=2048) =5.59, p<.05) and Arts modules (X² (1, N=1783) = 6.65, p<.01), the OU Analyse teacher groups had higher formal withdrawal rates, while in the case of the Law module (X² (1, N=2066) =5.61, p<.05) significantly lower formal withdrawal rates were observed for the OUA group
Higher completion and pass rates for OUA modules:
statistically significant differences in the Education (X² (1, N=3101)= 4.23, p<.05) and the Law modules only (X² (1, N=2060)= 5.91, p<.01). The OUA teacher groups had a higher module completion rate compared to the non-OUA groups in both modules. In terms of pass rates, significant differences were observed in the Law module only with the OUA group having a higher pass rate (X² (1, N=2066) =6.9, p<.01) (see Table 4).

From 10 modules 8 had no differences or negative picture for PLA – is this bc teachers did not log in systematically to the system?
