Benefits of Robots in Education<br />
This study explored the effectiveness of robots in an educational setting. The effects of robots using gestures and how it can help be used as an educational<br />
tool will be explored. This is a relatively new area of study. The Study discussed why humans use gesturing in addition to speech, the different types used and<br />
the effects they can have. There are a variety of different types as described in multiple published literature. The types used are established by Kendon (2004).<br />
Iconic gestures present imagery of an established concept or action, whereas Metaphoric are based on creating a new image in the observers mind. Deictic are<br />
pointing style gestures, and Beats are timing based. Other studies show that age has an effect on the interpretation and use of gestures, older adults tend not<br />
to use iconic gestures and interpret co-speech less (Cocks and Morgan, 2011). Whereas younger humans are more influenced by gestures when interpreting<br />
multimodal speech (Vocal and gesture synchronised).<br />
Project summary<br />
The project is to understand the learning<br />
effect of a robot using gestures in an<br />
educational setting.<br />
Teaching uses gestures as an additional teaching tool (Goldin-Meadow et al.<br />
2013), mimicking gestures used as part of an explanation which can help<br />
with deeper learning. Robots are starting to appear in the classroom in<br />
various forms and uses. In a few cases Robots are used to teach children.<br />
Robots who use gestures can make them appear more human, if a correct<br />
gesture is used at the correct time then the appearance of human qualities<br />
are increased.<br />
The Experiment was performed in a<br />
local nursery. The Preschool group<br />
participated being the eldest group.<br />
They have understanding of<br />
numbers so suited the math based<br />
test and lesson.<br />
A pre and post-test was conducted<br />
around each lesson where the<br />
children were asked to recognize a<br />
set of numbers.<br />
The robot<br />
here is<br />
producing a<br />
number 2<br />
gesture.<br />
4 Conditions were set for this experiment. Robot and<br />
Human teacher. For each of these the teacher would<br />
be using either gestures (tracing) or pointing only.<br />
Two sets of numbers were used over 2 weeks.<br />
Set A: 1,2,3,4,5, 21,22,43,24,45,41<br />
Set B: 1,2,3,4,5, 35,34,52,31,54,50<br />
The test was run over two weeks and the children<br />
experienced a different set of numbers each week.<br />
Project Objectives<br />
Compare the effects of a robot using gestures and pointing<br />
only. See if the robot created a better learning effect<br />
compared to that of a human.<br />
Project Conclusion<br />
The results concluded that the robot was less effective<br />
due to distracting the child from the information being<br />
processed. Additionally the robot is unable to produce the<br />
same effect due to not gaining the trust of the children<br />
due to the emotional connection of teachers.<br />
The children enjoyed the experience of the robot but<br />
found the human condition more comfortable and<br />
beneficial.<br />
The children's attention was also greater with the human<br />
teacher compared with the robot.<br />
Overall the robot did not perform as well as the human<br />
teacher. This is due to the robot not being a human staff<br />
member of the nursery and therefore not a respected in<br />
the child’s mind.<br />

The results shown that the robot had a negative<br />
effect on the children’s learning. This had many<br />
possible reasons.<br />
The human teacher performed better overall. The<br />
robot pointing only had a marginally bigger result<br />
than the human pointing only.<br />
The children paid more attention to the human<br />
than the robot.<br />
