Approach

In order to find out how the perfect study buddy system should be designed, we will perform a literature study about the needs of feeble-minded children in elementary school. Furthermore, elementary school teachers will be interviewed to assess to what extent the teachers believe the virtual study buddy system will be effective, and to find out what functions and characteristics the system should have in order to become effective. We will use this information to create several personas that represent the primary users. Based on these persona’s and additional literature, we come up with a digital learning platform that allows students to select from an array of topics the topic the need more help with. We will create only part of this platform that will explain, elaborate on, and test the topic of fractions in primary school arithmetic. We will then test this prototype of the virtual platform with real elementary school kids, after which we will let them evaluate the system’s effectiveness. This will show us what can be improved further afterwards.

Introduction

Since the introduction of the Dutch “Wet Passend Onderwijs” in 2014, elementary school children with physical or mental disabilities are stimulated to follow regular education as much as possible (“Scholen voor speciaal onderwijs bezwijken onder wachtlijsten,” 2019). However, according to Wim Ludeke of the Landelijk Expertisecentrum Speciaal Onderwijs (LESCO), the number of children applying for a custom form of education is increasing. The reason is that, as a result of the current lack of elementary school teachers (Traag, 2018), teachers of “regular schools” do not have the time and resources to support these children, and thus they are sent back to schools with extra support. In the Netherlands, there are approximately 2.2 million people considered to have low intellectual ability (“Prevalentie van verstandelijke beperking,” 2020), which means they have an IQ-score between 70 and 85 (Bexkens, Petry, Graas, & Huizinga, 2018). According to the CBS’ population counter (2019), the actual amount of Dutch inhabitants is 17,420,249. This means that about 12.5% of the Dutch inhabitants is considered feeble-minded, or less intellectually capable. In a letter to the Dutch Parliament, the minister for elementary and secondary school education wrote that primary school classes consist of 23.0 children, on average (Slob, 2019). Between the age of 4 and 11, there are about 35,000 children that get a special kind of education (“Speciaal basisonderwijs,” 2019). Furthermore, there are about 1,500,000 children in total that get primary education (“Ontwikkeling van het aantal leerlingen,” 2018). Taking these numbers into account, each class in regular primary education is bound to accommodate at least two children that are feeble-minded, on average. This means two children that require extra attention from their teacher during their education, attention which cannot be given to them in the current state of Dutch education.

Subject

A study buddy robot that helps elementary school children with a relatively low IQ understand and practice material taught in class better.

Problem statement

This introduces the problem that children with a need for special education in schools that provide regular education cannot receive an optimal tuition. The focus in this research will be on feeble-minded elementary school children. These children often experience difficulties with learning. For example, they often fail to understand a novel concept the first time it is explained in class, because of which they might need an extra, more elaborate explanation of the concept (Ahmad, Mubin, & Orlando, 2016). In circumstances like this, the teacher often lacks the time to provide this kind of extra tuition, but a robot providing a virtual learning platform in the class could repeat it as many times as necessary, and elaborate on the content as much as needed.

Objectives

The aim of our literature study is to define a robot that can act as a study buddy to help feeble-minded children in elementary school keep up with the pace of fellow students. Our goal is to develop a prototypical, virtual platform displayed on the robot’s interface that can repeat, elaborate on, and test topics of interest that feeble-minded children did not understand the first time a teacher explained it to them. Therefore, we aim to make the regular Dutch education more effective and accessible for elementary school children with an IQ below average between 70 and 85.

Users

Eventually the user group will consist of all scholars and/or students. For now, the focus is only primary school students of the Dutch 'group three until eight', those students are normally between 6 and 12 years old. Users that will use the app the most and the app is designed for, are scholars with low IQ.

Primary Users

The primary user in this report will be defined as the person that actually works and interacts with the study buddy robot. Therefore, the primary user will certainly be the somewhat less cognitively capable elementary school students that need some extra guidance during class. After the teacher is done explaining some new content, the robot will approach the student and briefly quizzes them on the topic just explained to see if they perform well enough to indicate they get the basic content of what was explained.

Furthermore, the teachers are considered to be a primary user, because they need to specify which topic was treated in class in order for the robot to approach the children with the right study material. So, the teacher also works with the study buddy first-hand in terms of setting up the robot’s study plan. Moreover, the teacher will keep track of the students’ progress after working with the study robot.

Secondary Users

Secondary users of the teaching robot are classified as people who may be indirectly influenced by the system in some way. In this case, where we assume a class in regular education with a relatively small amount of feeble-minded students that require a study buddy robot, the secondary user would be the classmates that are not assigned a study robot. An influence of a peer’s study robot on classmates might be a disruption of classmates’ concentration due to sound expressed by the robot during one of its explanations, or simply due to distracting images on the robot’s interface.

Requirements

The virtual study buddy shall:

• have an touchscreen as an interface to communicate the content of the class with the student.
• be able to express emotion by the virtual robot.
• understand the emotional state of the student and communicate accordingly.
• be able to keep track of the progress of the user.
• have a kind, anthropomorphic exterior.
• be able to approach the pupils in class.
• motivate (less cognitively capable) children to study newly taught material.

Robotic Basis

Our State-of-the-Art was first about all different (robotic) study buddies and the effects on it, see the section 'Other sources'. After this research we decided to only focus on the use of Haru as a study buddy, for this we did investigate Haru and its capabilities. Finally, a research is done to already existing online learning platforms since we want to combine Haru and a self-made online learning platform.

Haru

The robot Haru

The image on the right shows the desktop robot Haru, designed to be a social companion robot for people of any age. In designing Haru, empathy was a key consideration, it can signal emotion through body movements and visual elements such as eyes and color (Gomez, Szapiro, Galindo, & Nakamura, 2018). In the future, it will be able to recognize persons and their facial affect to improve empathic interaction. Haru robot can therefore interact with people appropriately due to the incorporation of current emotions in the interaction, which allows for communication according to the emotional state of the person it interacts with. To signal a feeling of proper understanding, the robot should be able to express a wide range of emotions. This range is visualized in the figure below:

The emotions Haru can express

Because of the robot’s anthropomorphic shape, it can facilitate human-robot interaction, because it “incorporates the underlying principles and expectations people use in social settings in order to fine-tune the social robot’s interaction with humans” (Duffy, 2003).

However, Haru does not have a voice yet (Aylett, Sutton, & Vazquez-Alvarez, 2019).This means a robot like this is purely useful for showing information on its screens that does not require additional sound, such as chapters from a book. If Haru would be used for the implementation of the study buddy, we would have to record voices ourselves. In the study of Fischer, Niebuhr, Langedijk and Eisenberger (2019), different voices are compared over different robots. They did include Haru to their research as well and found out that for Haru the best voice has a melodic dominance compared to a physical dominance. Fischer, et al. describe physical dominance as a result of different vocal tract sizes in humans, the melodic dominance is explained as difference in pitch. Fischer, et al. propose to research the fact that Haru has no arms and the relation of it to speech perception. Furthermore, Haru is a desktop robot, so it would not be able to approach people, as we aspire to achieve with the study buddy.

Haru would be a useful foundation for our study buddy, because it is so much focused on empathy, and recognizing and signaling emotion. If it were to approach children in class, the robot needs to do so keeping in mind it is interacting with children that require a unique, individual approach. Furthermore, the two interfaces Haru possesses to display its eyes can be used to display the virtual learning platform on, so no external interfaces are required.

NAO by Softbank Robotics

NAO by Softbank Robotics (2018)

NAO by Softbank Robotics (2018)

NAO is a robot, created by Softbank Robotics (2018). The first version was developed in 2006, the most recent version was developed in 2018 and is the sixth. NAO is a robot, 58 centimeters tall, it is a human-like robot which means it has arms, legs, a body, and a head. NAO has rounded features which are described by Softbank Robotics as ‘pleasantly rounded’. These rounded shapes contribute to the anthropomorphic evaluation of NAO. Besides, on the website of Softbank Robotics, six features of NAO are presented too shortly summarize the possibilities of NAO:

1. 25 degrees of freedom which enable him to move and adapt to his environment
2. 7 touch sensors located on the head, hands, and feet, sonars and an inertial unit, to perceive his environment and locate himself in space
3. 4 directional microphones and speakers to interact with humans
4. Speech recognition and dialogue available in 20 languages
5. Two 2D cameras to recognize shapes, objects, and even people
6. Open and fully programmable platform

This robot thus has a wide range of abilities. It can also talk, give its eyes different color to signal emotion, and use its anthropomorphic shape to make it feel connected with people. However, NAO does not have a built-in touch screen interface on which we would like to project the online learning platform to help children study, which means an external tablet would be required in addition to NAO. Therefore, the use of NAO would be a cumbersome way to teach feeble-minded children in class, because the robot is solely used to interact with the children and to motivate them; purposes that Haru can fulfill, too.

Online learning platforms

In this section research is done to already existing online learning platforms.

Concept

The main idea of the robot is that it has a screen on which it can display the online learning platform are developing, and that it is mobile enough to approach children in class. The robot will approach the kids, because children might fear situations in which they face criticism or in which they feel they might make themselves look ridiculous to others, which is a very prevalent social anxiety children have to deal with (Möller & Bögels, 2017). This might result in the fact that our target students might be less inclined to let the teacher (or the robot, for that matter) know they did not understand a concept out of fear of feeling criticized. Moreover, a positive relation is found between intrinsic motivation and academic achievement in young children (Broussard & Garrison, 2004). This implies that our target group—low-IQ children—will have less motivation to study and improve at school. Therefore, the robot should also be able to generate motivation in children to make them eager to study with the robot. An anthropomorphic shape of the robot is necessary to achieve this, because—in individual training, as is the case with our target group—a human-like appearance further encourages users to interact with the machine, which allows for more training opportunities than would have been available in the case of a non-anthropomorphic robot (Złotowski et al., (2014)). The robot that is chosen as the basis for this project is Haru. This robot satisfies the requirements of having an interactive interface that can be used to display the learning platform; and an anthropomorphic shape which allows for an motivating connection between Haru and the children. Furthermore, the aim for Haru was to build a personal robot that people would really love and feel connected to (Ackerman, 2018), which can make learning for these children more fun and effective and generate the intrinsic motivation feeble-minded children require to start studying with the robot. However, Haru lacks the mobility to approach children in class, an ability NAO does possess, so until future developments on Haru are established to make it mobile, Haru can only be used as a desktop robot in class that should be on the tables of the less cognitively capable students.

In order for the robot to approach the student, it will need to be able to draw their attention appropriately. According to Torta (2014), the most common interaction cues in joint attention are gazing movements and pointing gestures. Waving to get attention is generally considered to be more pleasant and friendly than making eye contact, and it is processed faster than blinking. However, it might be the case that the robot’s physical shape does not allow it to wave. In this case, it should be noted that just looking at a person might be considered not very friendly, according to Torta (2014). Therefore, an auditory cue should be integrated, such as the robot’s saying “Hello” to draw attention.

Face or voice recognition

In order to make it possible for every student to have a private account, the suggestion is to include face or voice recognition. Since the children are feeble minded, they may have difficulties in remembering a password. Besides, filling in your ID and password every time Haru is used would take a lot of unnecessary steps. Therefore a face or voice recognition can be a reasonable addition to the Haru assistant. Whether face or voice recognition is better or more convenient to use, depends on the camera and microphone Haru is equiped with.

State of the Art

In this section, research is done to investigate what is already known about (robotic) study buddies. Twenty-five articles are found, each article is shortly described to end up with an overview about different studies on study buddies.

The PAL project develops a conversational agent with a physical (robot) and virtual (avatar) embodiment to support diabetes self-management of children ubiquitously. Their conclusions are that children felt stronger friendship towards the physical robot than towards the avatar. The more children perceived the robot and its avatar as the same agency, the stronger their friendship with the avatar was. The stronger their friendship with the avatar, the more they were motivated to play with the app and the higher the app scored on usability.
