Approach

The objective of our robot is to help teach young children to count, and do simple arithmetic calculations. The way in which we aim to facilitate this is by letting the children explore the robot, while also providing nudges towards the correct answers, along with simple rewards for good results.  \\

Over the course of this project, we will create a simulation of our prototype that can be used for testing. However, we will not be testing the prototype on our target group, since our target group is very young children. Our goal is to provide a working simulation that responds appropriately to user inputs, testing different methods of reward and timing for nudges.

Schedule

Week 1 Week 2 Week 3 Week 4
Literature Reading Interview preperation & further literature study Conceptualizing

In the first week, we will mainly focus on literature reading. Getting to know the state-of-the-art and the best approaches to teaching children is key to figuring out our design. Then in the second week, we will apply this knowledge to concept design. We will discuss and determine what our counting robot will look like, such that it fits all requirements. We will start building or simulating our design in the third and fourth weeks. Based on the literature and our finalised concept from week 2, we will determine whether we are building a physical robot, or just simulating it.

Week 5 Week 6 Week 7 Week 8
Finalizing Prototype Testing Final Adjustments Documentation

In the fifth week, we should almost be done building/simulating and we can finalise our prototype. Then we will move on to testing in the sixth week. With the results of our tests, we can make some final adjustments to our robot in week 7. Throughout the entirety of our project, we will document our findings, but in week 8 we can finalise this to be readable.

Milestones

Throughout the project the team has several milestones to be reached, namely having:

  • gathered sufficient knowledge of the domain's state of the art;
  • found an open problem in the current state of the art;
  • created a concept design for a solution to the problem;
  • created a prototype for the concept design, this could be a physical prototype or simulation;
  • created detailed documentation on the design so that the solution can be physically implemented.

Deliverables

We will have several deliverables throughout this project:

  • After week 1: A set of 30 literary pieces about education, learning how to count, using visualisations for teaching
  • After week 2: A concept, with sketches and a clear description of our intended prototype.
  • After week 5: A first prototype.
  • After week 7: A second prototype, debugged through testing.
  • After week 8: A report on our findings.

Division

For the first week, the division will be pretty evenly distributed over the needed information for our meeting with the tutor on Monday, 19th of February. Once we have a good concept of our idea in week 2, we can clearly define tasks and divide these among everyone based on their skill set.

Approach

The digital abacus has 10 horizontal rods, each containing 10 beads. These beads can be slided by the user or by the robot itself using motors. The abacus has sensors to measure the position of each bead. It has 5 buttons: The goal button, check button, reset button, solve button and another button to switch between the different modes.

The abacus can be used to teach children how to count. When the goal button is pressed, the robot gives the user a random goal number using the speaker and shows that number on a display. If the user presses this button again, the speaker states the goal number again. When another button, the check button, is pressed. The robot tells the user what the current number of beads on the left side of the abacus is. If this number matches the goal number, the user wins and a victory jingle is played. When the reset button is pressed, all beads move to the right side of the abacus and the goal number gets reset. When the solve button is pressed, the abacus shows the solution by using the motors to move the correct amount of beads to the left, one by one, while using the speaker to count the number of beads it slides.

The abacus can also be used to teach children how to perform addition and subtraction. When the goal button is pressed, the robot gives an operation like 3+3 or 5-2. Just like the counting problem, the user tries to solve the problem and presses the check button to check if the task is performed correctly. Here, the top row represents the ones, the second row represents the tens etc. Multiplication and division can also be done using the abacus. Then, every row represents the ones. In the operation 3x2 for example, the user may slide 2 beads of the first 3 rows to the left. The user may use a button to change between the different modes.

Plan

Many children struggle with learning how to count. Addition and multiplication are difficult subject to master, so we want to develop a digital device to help teachers and students: a digital abacus. First we will look into visual learning and how to teach math using visualisation, which we can then apply when designing the device. Then we will start designing either a physical prototype or a simulation of our counting device.

Marty serves not just as an educator but also as a motivator, making the learning journey a joyful and enriching experience for young minds.

Users

Between 2% and 10% of the world population has Dyscalculia [1], this means that those people have much harder time learning mathematics than most other people. Which calls for a lot of extra practise, for those people it would be fun to have an tool that helps you and give feedback on the calculations, making them potential users for the product.

Furthermore, everyone on earth has to learn how to count and calculate at some point in their life, and it has been proven that for most people a visual explanation helps to see how mathematics works and makes it easier to do the calculations [2]. That means that also ground schools would be possible users of our product, to help the teacher teach this to the students.

Another user would be office workers that have to add a lot of numbers. Of course it seems logical to use an actual calculator at first. But adding the visualisation to the calculator gives a much better overview of whats happening to the numbers than adding raw numbers, this could reduce the amount of errors made, which would be very helpful for companies.

Literature

Education of Mathematics

Jordan, N.C. & Levine, S.C. [3] talk about how many children from low-income families struggle with mathematics and are performing on a lower level than their peers. Most children should enter school with some level of number skills. On these skills are built and more concepts are learned. These skills can be split into several types of knowledge. Preverbal number knowledge can already be shown in infants. They know how to represent a number in a nonverbal manner. This knowledge is as good as natural and does not require any outside input. However, after preverbal number knowledge, a child should develop symbolic number knowledge. This type of knowledge should be developed before and during the time the child goes to school, but does not come naturally. In their early childhood, they should be taught the following concepts: subitizing (recognizing sizes of sets without counting), counting, numerical magnitude comparisons (which number is bigger), estimation, and arithmetic operations.

Problems occur when learning these concepts. Many children count on their fingers, which leads to mathematics learning difficulties in the long run (this same problem might occur on our abacus).

To help children with mathematics learning difficulties, several solutions are effective. For example, board games involving linear number representations (such as chutes and ladders) [4].   

Gervasoni and Sullivan (2007) [5] investigate the vulnerability of children in 4 domains of number arithmetic: Counting, Place Value, Addition/Subtraction strategies and Multiplication/Division strategies. They find that there is no single method of for describing children who have difficulties with mental arithmetic nor their instructional needs. It also finds that a student being vulnerable in one domain, does not imply that they are vulnerable in another.

Buckingham (1935) [6] asks the question of when to begin teaching arithmetic to children. At the time the paper was written, students were being taught arithmetic since the first grade. The question was then asked whether arithmetic should be postponed until a later grade. An earlier investigation concluded that arithmetic taught in the first two grades was not needed. It is shown that a subject should be taught when the student is ready for it, and has utilities for it outside of school. The author states that children are ready and have use-cases for arithmetic outside of school already in the first grade. Relating back to the earlier investigation that concluded that arithmetic taught in the first two grades was not needed, the author proposes that the arithmetic taught in these grades were simply not the right type of arithmetic. In the earlier grades, students should be exposed to concrete arithmetic rather than to abstract arithmetic.

Visualization and Education

Vavra (2011) [7] shows how important visualisation is in education.

Robotics and children

Mubin (2013) [8] gives an overview of the field of robotics in education. It provides classifications for robots in education, such as the domain or subject of the Learning Activity or where the learning takes place during the Learning Activity. It also discusses some open areas of researched which have not yet been investigated at the time.

Konijn et al. (2020) [9] gives an overview of the research into robots in education. The overview mainly consists of conclusions of experiments where robots were shown to have positive effects in education. One important take-away from the paper is that the social behaviour of educational robots should be tailored to the person being targeted. Examples and experiments of this are given in the paper.
