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

Aim of this study

Evaluate whether providing teachers with PLA data would empower them to identify and assist students in need for additional support

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?

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

12

Page 13: Lak2017 Herodotou, Christothea

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

Page 14: Lak2017 Herodotou, Christothea

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

Page 15: Lak2017 Herodotou, Christothea

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
