Case study. The Ada chatbot: personalised, AI-driven assistant for each student.

As part of the AI and vocational education and training project funded through the EU Erasmus plus project we are producing a series of case studies of the use of AI in VET in five European countries. Here is my first case study – the Ada chatbot developed at Bolton College.

About Bolton College

Bolton College is one of the leading vocational education and training providers in the North West of England, specialising in delivering training – locally, regionally and nationally – to school leavers, adults and employers. The college employs over 550 staff members who teach over 14,500 full and part time students across a range of centres around Bolton. The college’s Learning Technology Team has a proven reputation for the use of learning analytics, machine learning and adaptive learning to support students as they progress with their studies.

The Ada Chatbot

The Learning Technology Team has developed a digital assistant called Ada which went live in April 2017. Ada, which uses the IBM Watson AI engine, can respond to a wide range of student inquiries across multiple domains. The college’s Learning Technology Lead, Aftab Hussain, says “It transforms the way students get information and insights that support them with their studies.” He explains: “It can be hard to find information on the campus. We have an information overload. We have lots of data but it is hard to manage. We don’t have the tools to manage it – this includes teachers, managers and students.” Ada was first developed to overcome the complexity of accessing information and data.

Student questions

Ada is able to respond to student questions including:

  1. General inquiries from students about the college (for example: semester dates, library opening hours, exam office locations, campus activities, deadline for applying for university and more);
  2. Specific questions from students about their studies (for example: What lessons do I have today/this afternoon/tomorrow? Who are my teachers? What’s my attendance like? When is my next exam? When and where is my work placement? What qualifications do I have? What courses am I enrolled in? etc.)
  3. Subject specific inquiries from students. Bolton College is teaching Ada to respond to questions relating to GCSE Maths, GCSE English and the employability curriculum.

Personalised and contextualised learning

Aftab Hussein explains: “We are connecting all campus data sets. Ada can reply to questions contextually. She recognises who you are and is personalised according to who you are and where you are in the student life cycle. The home page uses Natural Language Processing and the Watson AI engine. It can reply to 25000 questions around issues such as mental health or library opening times etc. It also includes subject specific enquiries including around English, Mathematics and business and employability. All teachers have been invited to submit the top 20 queries they receive. Machine learning can recognise the questions. The technical process is easy.” However, he acknowledges that inputting data into the system can be time consuming and they are looking at ways of automatically reading course documentation and presentations.

All the technical development has been undertaken in house. As well as being accessible through the web, Ada, has both IOS and Android apps and can also be queried though smart speakers.

The system also links to the college Moodle installation and can provide access to assignments, college information services and curriculum materials. The system is increasingly being used in online tutorials providing both questions for participants and access to learning materials for instance videos including for health and social care.

It is personalised for individuals and contextualised according to what they are doing or want to find out. Aftab says: “We are looking at the transactional distance – the system provides immediate feedback reducing the transactional distance. “

Digital assessment

Work is also being undertaken in developing the use of the bot for assessment. This is initially being used for the evaluation of work experience, where students need to provide short examples of how they are meeting objectives – for example in collaboration or problem solving. Answers can uploaded, evaluated by the AI and feedback returned instantly.

Nudging

Since March 2019, the Ada service has provided nudges to students with timely and contextualised information, advice and guidance (IAG) to support their studies. The service nudges students about forthcoming exams, their work placement feedback and more. In the following example, a student receives feedback regarding his work placement from his career coach and employer.

The College is currently implementing ProMonitor, a service which will offer teachers and tutors with a scalable solution for managing and supporting the progress made by their students. Once ProMonitor is in place, Ada will be in a position to nudge students about forthcoming assignments and the grades awarded for those assignments. She will also offer students advice and guidance about staying on track with their studies. Likewise, Ada will nudge teachers and student support teams to inform them about student progress; allowing for timely support to be put in place for students across the College.

A personal lifelong learning companion

For Aftab Hussein the persona of the digital agent is important. “In the future”, he says, “every child will have a personal lifelong learning companion which will support teaching and learning.” He thinks they will probably come from the big platform suppliers. Children will have their digital assistant from age the age of 3 or 4 and will have a Personal Learner Number allowing data to be exchanged between different institutions,

 

 

 

LMI for All API released

I have written periodic updates on the work we have been doing for the UKCES on open data, developing an open API to provide access to Labour Market Information. Although the APi is specifically targeted towards careers guidance organisations and towards end users looking for data to help in careers choices, in the longer term it may be of interest to others involved in labour market analysis and planning and for those working in economic, education and social planning.

The project has had to overcome a number of barriers, especially around the issues of disclosure, confidentiality and statistical reliability. The first public release of the API is now available. The following text is based on an email sent to interested individuals and organisations. Get in touch if you would like more information or would like to develop applications based on the API.

The screenshot above is of one of the ten applications developed at a hack day organised by one of our partners in the project, Rewired State. You can see all ten on their website.

The first pilot release of LMI for All is now available and to send you some details about this. Although this is a pilot version, it is fully functional and it would be great if you could test it as a pilot and let us know what is working well and what needs to be improved.

The main LMI for All site is at http://www.lmiforall.org.uk/.  This contains information about LMI for All and how it can be used.

The APi web explorer for developers can be accessed at http://api.lmiforall.org.uk/.  The APi is currently open for you to test and explore the potential for  development. If you wish to deploy the APi in your web site or application please email us at graham10 [at] mac [dot] com and we will supply you with an APi key.

For technical details and details about the data go to our wiki at http://collab.lmiforall.org.uk/.  This includes all the documentation including details about what data LMI for All includes and how this can be used.  There is also a frequently asked questions section.

Ongoing feedback from your organisation is an important part of the ongoing development of this data tool because we want to ensure that future improvements to LMI for All are based on feedback from people who have used it. To enable us to integrate this feedback into the development process, if you use LMI for All we will want to contact you about every four to six months to ask how things are progressing with the data tool. Additionally, to help with the promotion and roll out of LMI for All towards the end of the development period (second half of 2014), we may ask you for your permission to showcase particular LMI applications that your organisation chooses to develop.

If you have any questions, or need any further help, please use the FAQ space initially. However, if you have any specific questions which cannot be answered here, please use the LMI for All email address lmiforall [at] ukces [dot] org [dot] uk.

 

Wales to encourage schools to make full use of social networking technologies

Leighton Andrews, Wales Assembly Government Minister for Education and Skills, has announced an ambitious agenda in response to an independent review of digital classroom teaching. Of particular note is the commitment to “a new approach to the use of social networking technologies in education” through “encouraging schools to make full use of social technologies in order to engage learners and improve learning outcomes.”
Andrews says:

In previous years, local authorities have been asked to block access to social networking sites in schools, libraries and youth clubs, as a result of very understandable concerns about online predators, cyberbullying and the risk of disruption to classroom activities. However, this policy can have adverse effects. It deprives schools of access to tools and resources which might otherwise be used creatively and constructively in education both within and beyond the classroom. More importantly, it means that children are most likely to be using these sites outside the school, at home, or on mobile devices, in environments which may be unsupervised and where they have less access to informed guidance and support on how to stay safe online.
In 2008, Wales was the first country in the UK to introduce the teaching of safe and responsible use of the Internet into both the primary and secondary school curriculum. The underpinning approach was that we first teach children to use the Internet safely under supervision, and then help them to develop the skills and understanding they need to manage their own risk as they use the Internet independently. Enabling access to social networking sites in schools will be consistent with this approach, providing pupils with the opportunity to learn safe, responsible and considerate online behaviours in the context of supported educational activities. It will also help schools to include parents in these activities.”

We have long argued that blocking of social networking (and other web sites) in schools was a backward and futile step. Lets hope that other countries follow the lead of Wales.

Boundary Crossing and Learning

I have been long interested in the idea of boundary objects especially in relation to the use of technology for learning in the workplace. In general I think one of the issues with Technology Enhanced Learning is that we have tended to ignore the importance of physical objects in learning and practice.

Following the presentation by Alan Brown and myself on Technologically Enhanced Boundary Objects (for use in careers guidance) at the final Mature-IP review meeting, Uwe Riss kindly referred us to two papers:

This is Not a Boundary Object: Reflections on the Origin of a Concept by Susan Leigh Star

and

Boundary Crossing and Boundary Objects by Sanne F. Akkerman and Arthur Bakker.

Sadly neither is available for open access (I have university access but I find it Customized Inflatables very frustrating when there is no open access to important work).

I haven’t read Star’s paper yet, but found the paper by Akkerman and Bakker very useful. They define boundaries as “sociocultural differences that give rise to discontinuities in interaction and action.” They have undertaken an extensive literature review of the use of the idea of boundary crossing in education. In particular I think that Baktin’s idea of ‘dialogicality’ helps explain how learning takes place with multiple sources of ideas and knowledge (which some are referring to as ‘abundance’, through the internet as well as through structured, course based learning.

Bakhtin’s basic line of reasoning was that others or other meanings are required for any cultural category to generate meaning and reveal its depths:

Contextual meaning is potentially infinite, but it can only be actualized when accompanied by another (other’s) meaning, if only by a question in the inner speech of the one who understands. Each time it must be accompanied by another contextual meaning in order to reveal new aspects of its own infinite nature (just as the word reveals its meanings only in context). (Bakhtin, 1986, pp. 145–146)

This Bakhtinian notion of dialogicality comes to the fore in the various claims on the value of boundaries and boundary crossing for learning: learning as a process that involves multiple perspectives and multiple parties. Such an understanding is different from most theories on learning that, first, often focus on a vertical process of progression in knowledge or capabilities (of an individual, group, or organization) within a specific domain and, second, often do not address aspects of heterogeneity or multiplicity within this learning process.

In the second part of their research Akkerman and Bakker look at the “four dialogical learning mechanisms of boundaries”:

  1. identification, which is about coming to know what the diverse practices are about in relation to one another;
  2. coordination, which is about creating cooperative and routinized exchanges between practices;
  3. reflection, which is about expanding one’s perspectives on the practices; and,
  4. transformation, which is about collaboration and codevelopment of (new) practices.

Careers seminar

The fourth UK ESRC seminar in the series on careers, will be hosted by the University of West of Scotland, Glasgow, on 29th November, 2011. The seminar title is: ‘Digital technologies: exploring emerging and potential uses to deliver enhanced careers practice’. A number of ICT and guidance experts will present, including Dr. Raimo Vuorinen, from Finland, whose presentation title will be: ‘The perceived role of technology and social media in career guidance among practitioners who are experienced internet users: chances and challenges’. As the detailed programme for the day firms up, will available shortly on the seminar website.
