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 />
