Some thoughts on AI in education

A recent post in the TES got me thinking once again about AI in the schools.   The post focused on parents fears about artificial intelligence use in schools stating 77% of parents expressed a concern over a lack of transparency.

Firstly before I get into my views on AI let me first take some issues with the reporting and with the parental perception part of the research.   Looking at the research which you can find here, the question asked of parents focused on the “consequences of the use of AI”.   This feels a little negatively biased to start with.    Under this banner question a serious of sub-questions were asked with the participants asked to respond with either don’t know, fairly concerned/very concerned or not very concerned/not at all concerned.  Again the options hint towards negativity and therefore introduce bias.   And finally the sub question itself in relation to transparency for example focused on concerns relating to a “lack of transparency”, again a negative implication and further negative bias.     It is also worth noting that the survey only had 1225 parents contributing.    I think this falls very short of a sufficient sample to draw any meaningful and generalisable findings.   Despite all of the above the TES decided to pick up and report the findings of “parents’ fear about artificial intelligence in schools” including indicating an “overwhelming majority of parents are concerned”.   I find it somewhat funny that concern of potential bias in relation to AI was reported in an article itself so loaded with its own bias.

So to my views;  I myself have concerns regarding AI use in schools however also see much potential.   Funnily enough the Nesta report to which the TES referred concludes that AI in education “promises much to be excited about.”

Given the negative bias in the TES report lets therefore start with my positive views as to the potential for AI in education.   AI is very good at identifying patterns and divergence from patterns within large data sets.    This makes them ideal for analysing the wealth of school and wider educational data which exists to help educators, those responsible for educational policy and decision making, school leaders and even the teachers themselves.    Now thoughts may instantly jump to achievement data sets resulting from testing, final exams or teacher awarded grading however the opportunities far exceed this area.   Take for example data taken from school Wi-Fi, where students are allowed access, in relation to student movements around the school.   This data might help a school reorganise the school day or restructure the timetable in order to become more efficient and maximise the learning time available.   It might also be used to redesign learning spaces or develop spaces for students to rest, take a break and address their wellbeing.  This is but one example of how AI might be used along with school data.

AI can help direct students to appropriate learning materials using data to identify the areas where students need additional support along with the best support materials to meet these needs.    Some platforms already exist and are exploring this opportunity including Century, a platform which I heard very positive stories regarding when recently speaking to students at a school using it.   Platforms like this might prove highly valuable additional resources to complement classroom teaching or to provide a more effective homework platform.   This area and use of AI is likely to continue grow with the development of more and more online learning content being key to this.

AI can help with teacher administrative tasks such as registration conducted via facial recognition or marking of tests by natural language AIs that can apply a given marking criteria to student submitted work.    We also need to recognise some of the AIs that are already available including voice recognition and dictation, which is now a feature of the MS office products.    Googles search facilities, a now standard feature used in schools and classrooms, also quietly uses AI yet we don’t bat much of an eyelid to it.

The negatives implications which exist in relation to AI generally apply beyond the educational context, albeit the educational context in teaching our future generations makes things all the more worrying.

AIs need to be taught and to learn with this done using training data sets.   The worry is that bias in the training data set will result in bias in the AIs decision making.    As a result an AI which was developed in the UK, and therefore trained using UK based data, and used successfully in UK schools may not be appropriate for use in schools in Asia or the Middle East due to its decision making being biased towards a UK context.   That said, this same issue would impact on any product or service, or even individuals where they seek to operate outside their normal context.   We all have an inherent bias, we “humans”, create the AIs and train the AIs so is it realistic to expect an AI without bias?  I suspect part of the issue is a concern in relation to a particular bias being introduced purposefully however I think it is more likely bias in AIs will arise accidentally as it general does within humans.

There is a concern that AI decision making based on large data sets may become impossible for humans to explain or understand, as the decision making process could be based on huge amounts of data.     This brings with it the concern that we may lose some of our control.   If a teacher recommends a career track for a student they will be able to explain how they arrived at this however if an AI was used, the teacher may be able to present the AIs findings but may be unable to explain or understand how this was arrived at.   How many parents who be happy with a suggested career path for their child without any explanation available?

Linked to the above is a concern of “determinism” where AI might identify an end point and then through its actions lead to this occurring.  So those students identified as achieving a C grade in GCSE might be presented with content and learning materials which lead them to achieve exactly that.  This concern is again about a lack of control however it could be suggested we are deterministic in some of the practices already in use widely in schools.   Take for example the setting of students into ability bands, is this not potentially deterministic as the students in the top band get the most challenging content which may enable them to achieve top grades while the students in the lowest band gets easier materials which means the don’t learn the more complex materials, and as a result are unable to achieve the top grades.    Also is there a danger of determinism every time a teacher reports a predicted grade to parents or where a school uses ALIS or other benchmarking data?

Overall AI is going to find increasing uses in schools.   My gut feeling however is that for the foreseeable future this will be very much in a subtle way as data analysis systems start to suggest areas to investigate within school data, accessibility tools including dictation and translation support students in class and AI driven learning platforms provide personalised learning opportunities beyond the classroom.   These are but a few examples of things already happening now.  These uses of AI are likely to become more common.   Discussion of AI reminds of a quote in relation to effective technology integration being such that the teacher and learners don’t even stop to think about the fact they are using tech, the tech use is transparent.   I think AI use is going to be exactly this, and the AI in Googles search goes some way to provide this;  When was the last time when you were conducting an online search that you stopped to think about how google search works and how AI may be involved?

 

 

 

 

Future Gazing: Artificial Intelligence (AI)

The phrase “future gazing” has came up recently so I thought it worth sharing some thoughts on the future of EdTech as I see them.     As such I intend to share a series of separate posts on different technologies which might have an impact on education in the years ahead.

Artificial Intelligence

This is a big topic in the wider IT world but also increasingly in education.   The challenge is that AI covers a multitude of sins plus the application of the different AIs are substantial.

The holy grail of AI, as I see it, is the general-purpose AI.   Am not going to spend any real time in this area as this is, in my opinion, some way off.    When it does become a realisation, there is great potent

ial for it to be used in education to supplement teaching staff both as a virtual teacher, a virtual classroom assistant or a virtual coach or mentor.     As I said however, this is some years off.

More specific purpose AIs are much more likely to make an appearance in the short term.   An example of this might be a Mathematics AI which students can pose questions to in natural language, and that will then either provide answers or direct students to appropriate learning materials.   This isn’t that far off and is being used already on organisations help pages.    It just hasn’t thus far been focused on education.

Another application of AI might be in its ability to recognise emotions and activities of students.   This is already in trial in China.   Basically, this involves a classroom camera and an AI which analyses the facial expressions of students along with what they are doing.   This information is then fed back to the teacher to inform learning.    The teacher will get information on the students which appear confused or upset, indicating possibly they are struggling with the materials, along with data on which pupils have been busy with the work, which have been raising their hands to ask questions or provide answers and those which have been more disengaged or not participating.    From this the teacher can then decide how to change the learning activities, target questions or revisit concepts.   I suspect this AI could also be expanded to look at teacher questioning and provide feedback and advice on the types of questions being asked, the frequency and who the questions are directed to.  It might also look at the engagement of students throughout the school day to try and identify trends and develop a structure for the school day which is more in line with the physiological and psychological needs of students.

School data analysis is one area where I think AI is very close to being usable widely in schools.    Schools already are sat on a wealth of data in terms of the student academic data, student demographic data and pastoral data among others.    AI or machine learning can easily analyse the data and identify patterns which humans may not be able to identify.     At a school level this can easily be applied to summative academic results, identifying how different student groups perform, allowing comparisons across subjects, etc, however as we gather more and more formative data these AIs will then be able to feedback to teachers in relation to areas which students do or do not understand.   It will also be able to identify whether there is a pattern across different teachers therefore suggesting a change to how a particular topic is taught, or whether it relates to a group of students or to specific related topics.

In the wider school there will also be opportunities for use of AI.   In the dining hall for example AI might be able to examine data to identify possible lunch timings to improve efficiency.    Analysis of book titles taken from the Library might help in providing a window into pupil preferences and interests.    AI may have the ability to examine parents evenings and parents meetings to try and streamline these events and ensure everyone gets to see who they need to see with a minimal period of waiting.    Machine learning may be able to examine teacher performance management data and identify opportunities for peer support and peer learning to occur, or to identify cross school professional development needs.   Facilities use might be analysed to identify when they are under-utilised and then seek to make them available to the local community.    Teacher work days might be optimised through AI recommendations resulting from an analysis of our working habits looking at when we tend to send emails, our timetable, who we commonly meet with, etc.   These are just some of the ways in which AI may makes its way into our school.

Artificial Intelligence is going to make an increasing appearance in schools.  I think this is inevitable.   In actual fact I would say to some extent AI or Machine Learning is already in schools possibly in the schools firewall or mail filtering solutions or in the network infrastructure.    Going forward however it will become much more visible as it enters more areas of school life.       Or maybe like all good technology use, may become more common yet will be transparent in its use, with users unaware of where AI is providing help, support and guidance.

I think the general-purpose AI, the Data from Star Trek TNG, or HAL for 2001: A Space Odyssey is some way off.   In the first instance AI will provide hints and tips as well as other low-level recommendations or suggestions.     It is to this, and the possible productivity and efficiency gains that may result, that we should therefore first look.
