Chances vs. Issues of Learning Analytics
Chances
1.Monitoring learning
while it happens
2.On demand Learning
Measures
3.Personalize education
4.Identify students
at risk early
5.Reflection and
Feedback support
Dangers
1. Data not protected
2. Anonymisation
3. Unfair discrimination
4. Different behaviour
through panoptic
effect
5. No trust into the
organisation
@Hdrachsler, #SR15

Step 1:
Short presentation of a vision (Marty)

Step 2:
Rate Vision on (Audience)

1. ‘haalbaar’ =‘feasible’

2. ‘wenselijk’ = ‘desirable’

By raising your hands!
Envision the future of Learning Analytics …
@Hdrachsler, #SR15
Vision 1: 2025, LA are essential tools for educational
management
10Pic by: Janneke Staaks, https://www.flickr.com/photos/jannekestaaks/14204590229/
• A wide range of data about
learner behaviour is used
• This generates good quality,
real-time predictions about
likely study success
• Learners, teachers,
managers and policymakers
have access to live
information from schools
Vision 2: 2025, Learning analytics support self-
directed autonomous learning
11Pic by: SparkFun, https://www.flickr.com/photos/sparkfun/4536382170/
• No Curricula and assessment
anymore
• Students create communities for
own learning goals
• Analytics support information
exchange and group
collaborations
• Teachers become MENTORS
Vision 3: 2025, analytics are rarely used in education
12Pic by: Tara Hunt, https://www.flickr.com/photos/missrogue/94403705
• Courses that are automated by
analytics are seen as inferior
• There have been major leaks
and misuse of sensitive
personal data
• All use of data for educational
purposes has to be approved by
the learners and inspectorates
Vision 4: 2025, classrooms monitor the physical
environment to support learning and teaching
13Pic by: SparkFun, https://www.flickr.com/photos/sparkfun/4536382170/
• Furniture, pens, writing pads –
almost any learning tool uses
sensors.
• Information is used to monitor
learners’ progress.
• Teachers are alerted to signs of
individual learner’s boredom,
confusion, and deviation from task.
Vision 5: 2025, most teaching is delegated to
computers
14Pic by: Charis Tsevis, https://farm6.staticflickr.com/5215/5470451264_c0612f2102_z
• Enormous datasets containing
information about millions of
learners
• Computers suggest successful
routes for learning
• Recommendations are better
informed and more reliable than by
even the best-trained humans
Vision 6: 2025, personal data tracking supports learning
15Pic by: SparkFun, https://www.flickr.com/photos/sparkfun/4536382170/
• Sensors gather personal
information about factors such as
posture, attention, rest, stress,
blood sugar, etc.
• This data helps people to master
skills as swimming, driving, and
passing examinations
• Programmes using this data to
optimise learning for different
ages and courses
Vision 7: 2025, individuals control their own data
16Pic by: Gideon Burton, https://www.flickr.com/photos/wakingtiger/3157622608
• People are aware of the importance
and value of their data.
• Learners control the type and quantity
of personal data that they share, and
with whom they share it
• Most educational institutions run
campaigns to raise awareness of the
risks and exposure of data
Summary of the audience
• The most feasible Vision at Serious Request is
Vision Number …
• The most desirable Vision at Serious Request is
Vision Number ...
• The most feasible and desirable Vision at #SR15 is
Vision Number ...
@Hdrachsler, #SR15
“The future of Learning Analytics” by Hendrik Drachsler, OUNL was
presented at 3FM Serious Request 2015 in Heerlen, Netherlands

  1. For example, when one competition asked teams to predict whether a student would drop out during the next ten days, based on student interactions with resources on an online course, there were many possible factors to consider. Teams might have looked at how late students turned in their problem sets, or whether they spent any time looking at lecture notes. But instead, MIT News reports, the two most important indicators turned out to be how far ahead of a deadline the student began working on their problem set, and how much time the student spent on the course website. These statistics weren’t directly collected by MIT’s online learning platform, but they could be inferred from data available.

  4. In 2015, companies were beginning to develop systems to recommend resources and to predict outcomes. By 2025, these systems are highly developed. A wide range of data about learner behaviour is used to generate good quality, real-time predictions about likely success. Learners, teachers, managers and policymakers all have access to live and accurate information about how well a learner is likely to do. Learners and teachers plan their work on the basis of reliable tools that can produce detailed and personalised recommendations about what should be done to achieve the best learning outcomes. A growing industry offers services to institutions and individuals, advising on how to respond to predictions generated by analytics, and how to take appropriate action in the light of recommendations. Accurate predictive information enables managers and policymakers to expand or contract learning provision before success or failure is evident: you don’t have to wait to see if a course is booming or failing, with funding changes happening quickly.
  5. In 2015, learners in educational institutions and in businesses had to follow a curriculum developed by others. In 2025, they create groups that work together to decide their learning goals and how to achieve these. A ‘Learning Trajectory System’ uses analytics to support information exchange and group collaborations, and learners receive support from mentors, rather than teachers. Activity towards a learning goal is monitored, and analytics provide individuals with feedback on their learning process. This includes suggestions, including peer learners to contact, experts to approach, relevant content, and ways of developing and demonstrating new skills. Formative assessment is used to guide future progress, taking into account individuals’ characteristics, experience and context, replacing exams that show only what students have achieved. Texts and other learning materials are adapted to suit the cultural characteristics of learners, revealed by analysis of their interactions
As a result, learners are personally engaged with their topics, and are motivated by their highly autonomous learning. The competences that they develop are valuable in a society in which collection and analysis of data are the norm. There is also convergence between the learning activities of the education system and the methods used by employees to develop their knowledge and skills.
  6. In 2015, many people hoped that analytics would be able to improve teaching and learning and the environments where these take place. However, in 2025, it is clear that there are many problems. Courses that are automated by analytics are seen as inferior, and learners have realised that they can game the system. There have been major leaks of sensitive personal data, and it is clear that, even where this has not happened, many companies have misused the data generated by their analytics. Many governments have ruled that individuals are the sole owners of the data they generate. All use of data for educational purposes now has to be approved not only by the learner but also by new inspectorates. In practice this has meant that use of analytics is restricted to summative assessment carried out by government agencies. A consensus has emerged in educational policy that the move away from learning analytics is not only ethically desirable, it is also educationally effective.
  7. In 2015, learning analytics were mainly used to support online learning. By 2025, they can be used to support most teaching and learning activities, wherever these take place. Furniture, pens, writing pads – almost any tool used during learning – can be fitted with sensors. These can record many sorts of information, including tilt, force and position. Video cameras using facial recognition are able to track individuals as they learn. These cameras monitor movements, and record exactly how learners work with and manipulate objects. All this information is used to monitor learners’ progress. Individuals are supported in learning a wide range of physical skills. Teachers are alerted to signs of individual learner’s boredom, confusion, and deviation from task. Teachers and managers are able to monitor social interactions, and to identify where they should nurture socialisation and cooperative behaviour.
  8. In 2015, people were beginning to assemble datasets that could represent learner’s activities. By 2025, these are used on a large scale in teaching, and this has led to the development of enormous datasets containing information about hundreds of thousands of learners. Analysing in detail the progress of such a wide variety of learners has made it possible to provide reliable evidence-based recommendations about the most successful routes to learning, as well as identifying the learning materials and approaches that are most suitable for each individual at each point in their progress. These recommendations are better informed and more reliable than those that can be produced by even the best-trained humans. Learners now spend most of their time working with analytics-driven systems, and the role of teachers has been reduced. Education policy is driven by the evidence generated by the use of these systems.
  9. In 2015, people were beginning to wear devices such as heart-rate monitors and run-trackers as they went about their daily lives. By 2025, sophisticated sensors can gather personal information about factors such as posture, attention, rest, stress, blood sugar, and metabolic rate. People collect this information about their activities, and feed it into programmes of their choice which provide recommendations on how to act in ways that improve their learning.  Learners can download the statistics and data that are associated with successful learning in a certain area. Aligning personal data with these ‘ideal’ sets is claimed to help people to master skills as diverse as swimming, driving, carrying out surgery and passing examinations. Academic stars sell programmes using this data to optimise learning for different ages and courses. Business gurus market similar programmes for topics such as presentation skills and workload management. Some learners create and share their own data analysis programmes, which provide recommendations that often include the consumption of high energy foods and stimulants. The majority of high school and university students follow self-monitoring programmes, and avidly discuss the merits of these on social media.
  10. In 2015, it was not clear who owned educational data, and it was often used without learners' knowledge. By 2025, most people are aware of the importance and value of their data. Learners control the type and quantity of personal data that they share, and with whom they share it. This includes information about progress, attendance and exam results, as well as data collected by cameras and sensors. Learners can choose to limit the time for which access is allowed, or they can restrict access to specific organisations and individuals. The tools for making these choices are clearly laid out and easy to use. In the case of children, data decisions are made in consultation with parents or carers. If they do not engage with these tools, then no data is shared and no benefits gained. Most educational institutions recognise this as a potential problem, and run campaigns to raise awareness of the both the risks of thoughtless exposure of data, and the benefits to learners of informed sharing of selected educational data.
