Why Robots? Robots shown to be effective in teaching
both typically developing and intellectually disabled children
Increases motivation and engagement – important factors in learning
BUT ◦ Small number of studies ◦ Focus mostly on autism, little research on PMLD/severe LD ◦ Wide variation in capabilities of “Robots”
![Page 3: Can Working with a Robot Enhance Learning in Children with Intellectual Disabilities](https://reader033.vdocument.in/reader033/viewer/2022042813/54930e96b479597e6a8b5a80/html5/thumbnails/3.jpg)
The NAO Humanoid Robot Produced by Aldebaran
robotics Aesthetic appeal Programmable ◦ New behaviours ◦ “Out the box” Sitting and standing Walking Dancing Playing sound files
Capable of autonomous behaviour sequences
![Page 4: Can Working with a Robot Enhance Learning in Children with Intellectual Disabilities](https://reader033.vdocument.in/reader033/viewer/2022042813/54930e96b479597e6a8b5a80/html5/thumbnails/4.jpg)
Aims To investigate the views of teaching staff
regarding the use of a robot ◦ What type of pupils they think might benefit from working with the robot ◦ Which learning goals they would target ◦ Which methods they would use to achieve them
To carry out a series of case studies to identify potential teaching strategies and possible outcome measures for a future evaluation.

Methods - Interviews
Semi-structured interviews conducted with all 8 participants
Audio-recordings of interviews transcribed verbatim
Transcripts read and re-read
Manual coding of transcripts
Repeated reading and refinement of transcripts and codes
Final codebook produced, containing both inductive and deductive themes
All transcripts coded according to codebook
Independent researcher calculated inter-rater reliability (71.4%)
8 Members of teaching staff recruited

Results - interviews Numerous themes found, both deductive
(i.e. expected prior to interviews) and inductive (i.e. derived from the interviews)
Broadly able to be divided into 3 categories, although some overlap: ◦ “Teacher factors” ◦ “Pupil factors” ◦ “Robot factors”
![Page 7: Can Working with a Robot Enhance Learning in Children with Intellectual Disabilities](https://reader033.vdocument.in/reader033/viewer/2022042813/54930e96b479597e6a8b5a80/html5/thumbnails/7.jpg)
Teacher factors Motivation of the gatekeepers to work
with the robot ◦ Perceived benefit ◦ Personal interest
The importance of training gatekeepers ◦ Practicalities of using the robot ◦ Effective teaching methods ◦ Delivery of training
How individual gatekeepers’ attitudes and skills may influence the use of the robot ◦ Time commitment ◦ Perseverance

Pupil Factors “Our students aren’t like other students” ◦ Need to “tailor make” sessions ◦ Similarities
“The thing is they always surprise you”
![Page 9: Can Working with a Robot Enhance Learning in Children with Intellectual Disabilities](https://reader033.vdocument.in/reader033/viewer/2022042813/54930e96b479597e6a8b5a80/html5/thumbnails/9.jpg)
Robot Factors The importance of “Productive learning” ◦ Threats to “Productive learning”
Empowerment The importance of accessibility Motivating and engaging students “It’s like a little person” Concerns about damage Concerns about the cost
![Page 10: Can Working with a Robot Enhance Learning in Children with Intellectual Disabilities](https://reader033.vdocument.in/reader033/viewer/2022042813/54930e96b479597e6a8b5a80/html5/thumbnails/10.jpg)
Pilot Study methods Used information from the interviews to
guide the design Learning goals tailored to each pupil Robot controlled using “Wizard of Oz”
technique 5 pupils, 5 sessions, 3 weeks Video recorded and analysed using
Obswin for 3 factors ◦ Engagement ◦ Assistance from teacher ◦ Goal achievement
![Page 11: Can Working with a Robot Enhance Learning in Children with Intellectual Disabilities](https://reader033.vdocument.in/reader033/viewer/2022042813/54930e96b479597e6a8b5a80/html5/thumbnails/11.jpg)
Pilot Study methods Teachers asked to complete “Engagement
Profile Scale” twice ◦ In class (standard lesson, without the robot) ◦ Looking at video of session 5 (with the robot)
This is an assessment tool developed by the Specialist Schools and Academies Trust (SSAT)
Rates 7 domains of engagement on a scale of 0-4, giving a total out of 28
Specific to the activity

Pupil 1 – Age 12 Aims: To learn the meaning of symbols through
interaction with the robot To recognise there must be an order to
some actions (e.g. Must stand up before walking)
To put together sequences of up to 4 actions

Pupil 2 – Age 10 Aims: To identify numerals up to ten, and
choose the correct one using a switch
![Page 16: Can Working with a Robot Enhance Learning in Children with Intellectual Disabilities](https://reader033.vdocument.in/reader033/viewer/2022042813/54930e96b479597e6a8b5a80/html5/thumbnails/16.jpg)
Pupil 3 – Age 11 Aims: To encourage vocalisation by repeating
what the robot says (using her own voice to increase engagement)
![Page 17: Can Working with a Robot Enhance Learning in Children with Intellectual Disabilities](https://reader033.vdocument.in/reader033/viewer/2022042813/54930e96b479597e6a8b5a80/html5/thumbnails/17.jpg)
Pupil 4 – Age 17 Aims: To correctly steer the robot from a start point to
an end point using a Smartphone’s accelerometer as a steering wheel.
To correctly answer questions about the direction travelled
![Page 18: Can Working with a Robot Enhance Learning in Children with Intellectual Disabilities](https://reader033.vdocument.in/reader033/viewer/2022042813/54930e96b479597e6a8b5a80/html5/thumbnails/18.jpg)
Pupil 5 – Age 9 Aims: To deliberately trigger the robot to
perform a desired behaviour To refrain from attempting to retrigger the
behaviour until the previous behaviour has finished completely.

![Page 21: Can Working with a Robot Enhance Learning in Children with Intellectual Disabilities](https://reader033.vdocument.in/reader033/viewer/2022042813/54930e96b479597e6a8b5a80/html5/thumbnails/21.jpg)
Results No significant changes in engagement,
teacher assistance or goal achievement over the 5 sessions ◦ Engagement sustained ◦ Changes in difficulty?

Limitations Lack of a closely matched control Small size Short duration Limitations of video analysis measures
![Page 24: Can Working with a Robot Enhance Learning in Children with Intellectual Disabilities](https://reader033.vdocument.in/reader033/viewer/2022042813/54930e96b479597e6a8b5a80/html5/thumbnails/24.jpg)
Conclusions Robot shown to increase engagement and
therefore learning This engagement was sustained
throughout the study Pupils able to have control using a wide
range of input devices Use of robots in education of children with
intellectual disabilities has enormous potential for the future

Future directions Further studies (longer, more participants) Refine methods Assess use in other situations (Adult
learners, medical education)
