Introduction

With the rise of technology comes new ways to implement technology into our daily lives. One of these implementations is technology in education. More specifically, we wanted to develop a technological tool that will help young children in their learning process of number sense. Your knowledge of counting and quantities is tested daily throughout your life. Not a day goes by where you do not have to count or decide the quantity of something, which it is such an important skill to learn from an early age. We wanted to make an application that teaches children number sense in a fun and easy way.

Teaching children to count is very important. It helps with their development as well as being used in day-to-day life later on. The current curriculum used in most schools works well, but we feel that implementing technology into this curriculum would improve the learning of small children, both in school and at home. According to Hsin (Hsin, 2014) , who studied the influence of children's use of technology on their learning, this technology does have a positive effect on learning. Hsin does provide us with a few conditions in which learning with technology is optimal. When children are allowed to work together and communicate with each other, technologies may not only improve knowledge, but social skills as well. These skills are most important for children, since interaction with others is needed for humans to survive. The second condition that needs to be met, is that adults need to be present to provide a safe climate and to encourage participation. This makes sure children stay motivated to learn and the adult can give guidance when instructions might be unclear. Our product is heavily influenced by these two conditions. What we designed is a web-based application that teaches children how to count and recognize shapes and color. It is targeted at children aged 3-5 that are at an average level of counting and shape / color recognition. It has a level-based design with three main levels. These levels then have several exercises each. The difficulty increases for each level, but stays the same within levels. OUr product is designed to be used in a classroom setting. It can be used on a whiteboard with a stylus or on a computer or laptop. When it is used on a whiteboard, children can interact and discuss with each other about the correct answer to the questions. This way, interaction and collaboration is promoted. When it is used in a classroom setting, the teacher can give extra help and information where needed, although the product is designed to need very little to none additional explanation. This wiki gives an overview of the research done for the project, the design behind the project as well as the website and its layout.

USE

User

The website described in this wiki is designed to teach young children how to learn counting, colors and shapes. The target user for the website is therefore children aged 3-5 years old. The website is targeted towards children of all education levels, as it can be both a learning tool as well as a revision tool. Since the user test was done by children of a Dutch primary school, the website is in Dutch. This means that for this course, the target group can be specified to only include Dutch children.

Society

The people that will benefit most from the website is schools and more specifically teachers. Tim's Telwereld was designed as an aid for teachers. It supplies a fun way for children to learn. This allows teachers to let children interact in a fun way with numbers and shapes, while not actively having to do anything. It allows teachers to reflect on the knowledge of the young children and to find possible gaps in their knowledge.

Enterprise

Tim's Telwereld can be interesting for business in a number of ways. First of all, there are improvements that could still be made. If a business picks up the project and continues working on it so that it can be released to the public, it can be sold to schools. It can be designed in such a way that only when a school buys the product, they (and the children they teach) can access the website. This allows businesses to implement several marketing strategies in order to sell a good product and make money out of it.

Currently a lot of money is made from the internet through digital advertisements. On almost all the websites available to the public, there are ads to the side or bottom of a webpage. This can also be done for Tim's Telwereld. Advertisement spaces can be bought for businesses to advertise their product or service. With this, however, comes the moral dilemma of advertising to young children, and whether this is ethical to do so. There are, however, already a lot of websites targeted towards children that have enabled ads, which could imply that it is a valid method of getting money, as long as the privacy of the user is taken into account.

Research

State Of The Art

There are already a lot of apps on the market that are geared towards educating children. Certainly apps that teach children how to count or how to draw separately. Combining the two is also done, but less frequently. One app and one website that combine learning to count and to draw are found on the internet. The first one is an app made by Bini Bambini and is called “123 tekenen tellen van nummers voor kinderen”. This game gives children very simple descriptions along with visual guides for drawing complex shapes. It then tells the child how many objects there are and lets the child draw the number. It does not have any AI to see what the user draws, it only gives an outline and a field in which to draw. Once the user stops drawing for a few seconds, the app goes on to the next step. The second one, a website, is called Kids Academy. This has the same general layout of the bambini app, only the Kids Academy focuses on more than just learning math. What stands out quite prominently in both apps is the design layout. It is clearly targeted towards kids with simple shapes, bright colors and audio directions instead of text. Our product keeps these general GUI attributes, but it is different in the level design. We combine drawing and counting in a different way. First, we start off with a level where children do not even need to draw and just need to recognize amounts, colors and shapes. Then, children need to draw (simple) shapes themselves, without guidelines, and also need to draw the correct amount eventually. This makes it so the child is more actively working on the amounts of objects, which will promote their learning.

How children learn

In order to develop an application that supports the learning of children aged 3-5, we first need to know how children's learning develops during their early years and what knowledge they already possess or still need to learn. From when they are born to around the age of 5, children develop something called “everyday mathematics”. This means they develop informal ideas of more and less, taking away, shapes and sizes. These everyday mathematics can be surprisingly broad, complex and sophisticated for children of a young age. Apart from the everyday mathematics that children learn and develop on their own, they also start learning mathematics in school. From the age of 2, children learn the language and grammar of counting. They memorize the first ten or so counting words, and then learn a set of rules to generate the higher numbers. When children are around 4 or 5 years old, they begin to develop metacognitive skills: they will become more and more aware of how they think about math problems and will start to say these thoughts out loud. The hardest form of language for children to learn, which they thus only learn at a later age, is the special written symbolism of mathematics, like 5, +, - or =.

Understanding numbers involves more than saying a few counting words. It involves reasoning about numbers, making inferences and developing a mental number line. Children also need to mathematize, they need to be able to think of problems in just mathematical terms. This means that they need to understand that when they combine one apple with two others, they can write this down as 1 + 2. This mathematizing is not very important for our product, as this only happens at a later age than the target group we are designing for. This means that we do not yet have to include problems of mathematization in our level design

The Number Worlds Curriculum

This curriculum is one of many out there that learns children what numbers are and how to use them. It provides a good understanding of the process a child goes through in order to learn how to count. Looking at 5-year-olds, there are several points of knowledge they need to know, relating to number sense . Five year old's know:

• that numbers indicate quantity and therefore, that numbers themselves have magnitude
• that the word “bigger” or “more” is sensible in this context
• that the numbers 7 and 9, like every other number from 1 to 10, occupy fixed positions in the counting sequence
• that 7 comes before 9 when you are counting up
• that numbers that come later in the sequence
• that are higher up - indicate larger quantities and therefore, that 9 is bigger (or more) than 7.
• that each counting number up in the sequence corresponds precisely to an increase of one unit in the size of a set. This enables children to use the counting numbers alone, without the need for real objects, to solve quantitative problems involving the joining of two sets. In doing so, it transforms mathematics from something that can only be done out there (e.g. by manipulating real objects) to something that can be done in their own heads, and under their own control.

As children get older, they progress through different knowledge they know: By the age of 4, children have constructed knowledge of counting and quantity. Sometime in kindergarten, children become able to integrate these knowledge networks. Around the age of 6-7, children connect this integrated knowledge network to the world of formal symbols. By the age of 8 or 9, most children become capable of expanding this knowledge network to deal with double-digit numbers and the base-ten system.

In the number worlds curriculum, there are 5 instructional principles that lie at the heart of the program:

1. Build upon children's current knowledge

2. Follow the natural developmental progression when selecting new knowledge to be taught

3. Teach computational fluency as well as conceptual understanding

4. Provide plenty of opportunity for hands-on exploration, problem-solving and communication

5. expose children to the major ways number is represented and talked about in developed societies

Lastly, the core of number sense forms a knowledge network that is called the central conceptual structure for number. This core is important for children for two reasons: 1) it enables children to make sense of quantitative problems across context, 2) it provides the foundation on which children's learning of more complex number concepts is built.

Stakeholders And SLO

Meetings with stakeholders were had in order to figure out what important topics they want to see included in the website design as well as other useful information they have on the learning trajectories of children. This resulted in a collection of information important for further development of the software model.

The stakeholders talked about what would make the software good in their perspective. Some of the topics they mentioned were a distinction between age groups, the software being available on a digital schoolboard, the importance of learning 'pen grip', the software returning performance data to the teacher (a 'test' system) and the relevance of a reward system.

The reason why a distinction between age groups within the level design was discussed, was because the stakeholders thought children from age 3-4 varied quite much in skill and learning goals compared to children from age group 4-5. They mentioned the following information about each of the age groups.

For the 3-4 year olds, they need easy levels. Drawing multiple different figures may be too hard. The children are usually already able to count to 10, via touch, so counting could be implemented. They can manage color and shape comparison, so asking for a certain colored and shaped object is an apropriate question. Additionally learing the pen grip is very important at this age, so levels where they can use a pen in a not too difficult task would be ideal. Listening skills, like those relating to executable tasks, are also important to learn at this age.

For the 4-5 year olds, they should be able to manage the drawing levels. For them it's still important to learn shapes in a more deepening way (reproduction rather than recognition). As well as listening skills, number recognition also becomes an important learning goal.

*What makes the software good?

- Rising level of difficulty (3-4 to 4-5 level ?)

- Possible on digital school board

- Possible with pen (learn pen grip)

- Returns performance data to authorized figure

- Test mode

- Feels like a game (reward system)

*What can kids learn from the software?

- Colors, Shapes, Counting & Drawing

- Pen grip

- Vocabulary (if drawing objects)

- Listening skills (if tasks given in audio)

- Number recognition (number on screen)

*Useful purposes

- Being able to use the software collaboratively (class setting, performing tasks together)

- Being able to use the software to test how far children are.

- Being able to have the kid perform tasks on their own, behind computer or tablet.

How The Research Is Used

As a basis, we will use Number worlds curriculum and SLO curriculum. These have been tested and used by many schools and education institutes around the world and are proven to support learning of children.

Number words has 5 principles for learning, we used them as a framework to develop good exercises that cater to the needs of the children that want to learn. Principle 1 talks about building upon children’s current knowledge. We do this by slowly incrementing the difficulty of our levels. First, we ask children to simply move an object into a box, then when they have mastered this, they need to move a specific amount or specific color or shape of object into a box. This way, we slowly add more variables while building onto the knowledge children already have. Principle 2 is about following the natural developmental progression when selecting new knowledge to be taught. With this, we looked at what knowledge young children typically learn at what age. We also took into account the desired age for users and combined this to find what lessons work best. For example, we use squares and circles for objects instead of cars and dogs, since the latter is too far ahead in the developmental progress of knowledge for the small children. Principle 4 talks about providing opportunity for hands- on exploration and communication. We hope to do this by making our product work as well on a digi board. This way, children and teachers can work together to solve problems and do exercises, promoting communication between them.

The SLO curriculum is one that does not just focus on math, or on younger children. It focuses on all subjects and children of all ages. For our application, we look at their learning materials for young children (ages 4-7) and specifically the math and number sense material. SLO works with "inhoudslijnen" that give an overview of everything the young child (until age 7) needs to be able to do and what knowledge they need to posses. Even though our app focuses on children ages 3-5, we can still use these "inhoudslijnen" to shape our exercises. Learning never stops, and everything we teach children at a young age, they do not need to learn at a higher age still. If we for example look at some of the learning goals of SLO, we can see that, at age 7, they want children to learn how to count to 20 and to also be able to count quantities of at least 20. At age 4 or 5, children using our app probably would not already be able to have knowledge on all these topics, as they are aimed at children aged 7, but we can give them a good push in the right direction. Since we know that children aged 7 need to know at least how to count to 20, then children aged 5 should not only be able to count to 5, but probably to 10 already. In conclusion, using the learning goals of SLO, we can modify them to set our own learning goals for users of the application. Based on these learning goals, we can then shape the levels of the game to teach the children just what we want to know.

SLO has learning goals for children. There are a few of those learning goals that are important for our level design: What we have now is doable for children aged 3-5 years old. What we might need to look out for is that it will not be too easy for 5 year old's, seeing as according to SLO, at that age they already learn additional things as well. What we have now as exercises follows the learning lines of children and will support their learning process. Nothing from the levels is too difficult, so it wont be the case that the level difficulty is above the level of the users. Related to language (listening/reading): reading is indeed too difficult for younger children. When you look at phase 1 of OSL, you can see it is mostly simple words and very very short sentences as well as looking at pictures. There is not a whole lot about listening, but according to the prephase (for ages 2-4) then children should be able to listen to and interpret explanations of exercises. We do have to keep in mind to only use very simple words

Software Model

Tim's Telwereld combines learning of shapes and numbers into a fun experience for young children. It is targeted at children aged 3-5 that are starting to learn number sense and shape recognition. It is a web-based design that is intended for use in the classroom, on digiboards or school computers. It is designed to follow the natural learning curve of children and to promote communication between users.

The homepage of Tim's Telwereld

The website itself is designed with the users in mind. Since the main users will be children aged 3-5, the website needs to be exciting and fun for them. This means the use of lots of bright colors and fun shapes or cartoons. The website also has little to no text, with instructions being given through audio. During the levels there is also a story element with small videos to keep the attention of the children. The buttons for the levels as well as those used for the drawing tool are all quite large. This makes it so even children that cannot move the mouse with a lot of accuracy can still click on the interactables with ease.

Level design

The first level of Tims telwereld

The levels are designed in a way to reflect the natural learning of children. There are 3 main moving levels, each with sub-difficulties that vary slightly. The first level is all about colors. In this level, users will have to move the correct colored object into a square box. This will make users get used to the layout of the website as well as teach them about the name of shapes and picking the right colors. The shapes are quite simple; circles, squares and triangles will be used.

When this first level is completed, the user moves on the second level where it is all about shapes. Here the idea is to move the object with the right shape between a range of same colored objects. Again, the amount of objects increases as the child moves up in difficulty.

For the third level shapes and colors are combined so that the task is to pick the object with the right shape and color at the same time. Difficulty again plays a role in the increasing number of objects and colors.

As potential for further development the concept of a fourth level could be to also introduce counting within these moving levels. As of now though, the attempt is to work counting into the drawing levels only.

Difficulty

To make sure the users will be engaged by the website, it is important to implement a range of difficulty that is able to build up in relation to the user's success rate. The user will have to successfully move through all difficulties of a level before being able to move on to the next level. The amount of difficulty has influence on the range of colors and amount of shapes that are available in the exercise. The difficulty will go up after a successful attempt at a level. The difficulty will stay the same and the child will be provided with a learning video after an unsuccessful attempt.

Image Recognition

In order to recognize images drawn by children, a neural network was used. In order to train this network, two databases were used. The MNIST dataset and the Google quick draw dataset .

Some code was also created which can read a database, build a neural network, train a network and test the resulting network. However, at first the results from the neural network were disappointing. At the start, the success rate of the neural network was 0.0036 which is worse than random guessing (which would be 1/250 = 0.004 with 250 labels). After a week, we decided to use a different dataset for the AI: the google draw dataset. The reason for the switch is because the google dataset has better support for simple shapes like squares and circles, which we will use for our final product. The downside of the google draw dataset is that it comes in 4 different formats, each of which has a different amount of preprocessing done to it, which made it hard to make an informed decision about it. One other downside to the different formats is that if we decided to switch to a different format, the part of the code that reads the input needed to be updated as well. In the end, we decided to look into the pros and cons of all four formats and decided on the 38x38 grayscale bitmap version of the original images. The reason for this choice is that the simple shapes will be easy to recognize even with this heavy downscaling and the low image resolution will result in shorter training times and a less complex neural network. This dataset we chose comes in a .npv format, which means that at the point of implementing it was incompatible with a lot of the code, which meant we had to update that. After implementing the new dataset, the AI had a significantly improved accuracy. It is currently at 97%. In the end, the AI was implemented on the website. This took some trial and error as the AI and the website did not have the same format (javascript vs python) butit worked in the end by using the tensorflow module from python. Code was also written that converted the drawn images from the users into a good format for the AI, which is a grayscale 28x28 image.

The Website

Designing the website

The website which holds the final product was made using glitch . This platform was chosen as it allowed the whole group to work together at the same time on the code, while also immediately seeing feedback on what the code changes to the website. Below are the links to the website as well as the code for the website:

The website: https://group3use.glitch.me/

The code: https://glitch.com/edit/#!/group3use

The code was designed in a distinctified way as to have each level link back or through to eachother. Each level has their own html page, for example for the first stage 'game1' containing information about the places and functions of all present objects. Linked to each of these html pages is a distinct javascript page containing functions for generating the randomized levels and level completion actions, for the first level this is called 'script1'. When a stage is completed the user is linked to a next html page, which depending on how far the user is becomes either a higher difficulty ('script1a') or the next level entirely ('script2'). At a later stage when the reward system was introduced, a separate page for showing the reward video was placed between the routes of stage to stage.

Reward system with a storyline

To make completing all the levels more appealing to children, a storyline will be shown through visuals in the levels and animated videos. This reward system is set up in the following manner. Before starting the drag and drop levels there is an introduction video that introduces the storyline and explains what the children need to do to complete the levels. After every completed level a small reward video plays that shows the children that they are doing something that impacts the storyline. After every few levels a somewhat larger video plays that updates the storyline a bit. If the children complete every drag and drop level a video plays that concludes that part of the storyline. The drawing levels have animated videos in the same places as the drag and drop videos. Testing our product in a classroom proved that the reward system was effective for at least the drag and drop levels.

The subject of helping animals was chosen for the storyline because it is observed to be a timeless subject for children. Things like tv-shows and apps geared towards children use animals very often. Testing our product also confirmed this.

A still from the storyline video

The overarching storyline is about a group of animals (a horse Pleun, a monkey Albert, a bunny Kiki and a tiger Tim) that are going on a summer holiday. The group however, has trouble reaching their destination because of a few obstacles that the children can help them with. The levels designed for 3-4 year olds are about the start of the journey, where all the animals get hungry. In each level the children drag a specific shape with a certain color into a box. If they do it right the video shows the shape transforming in food and one of the animals eating it. The videos updating the storyline show the animals getting less hungry and more energetic. Finally, the concluding video shows the animals having a full stomach and continuing their journey.

During the levels designed for 4-5 year olds the group of animals has almost reached their destination, which is a small house on the beach. But to get there they still have to cross quite a few rivers without bridges, and the children can help them build those bridges. In the levels they draw certain shapes that transform into bridges in the reward videos afterwards. The last concluding video shows the animals standing on the beach next to their holiday home. They thank the children for their help and can finally start their holiday.

Animating the videos

All the videos needed for the reward system of the drag and drop levels have been animated and added to the site. As much of the animated videos for the drawing levels as possible were also added to the website, which sadly was not all the videos, since the drawing levels couldn’t be finished in time. PowerPoint was used to make the animations.

Test plan

In order to make sure our product works as intended, user tests were run on children aged 5-6. Since there was limited time available for the study and design of the product (only 8 weeks), there was no possibility to test whether the product actually supports and improves learning for children. What was able to be tested, however, was whether children engage with the product and whether the product can keep their attention. In order to test this, a test plan was written out:

In total, the experiment will take an hour. This is not an ideal timeframe, but the children are only available for 1 hour. At the start of the experiment, there will be 15 minutes where the experimenter will explain to the children what the study is going to be about. The hypothesis will not be disclosed, but the general plan of the study will be. Somewhere before the study will take place, the teacher(s) present will be given a more thorough explanation as well. We will tell them the research question we want to answer, as they cannot influence the opinion of the children during the study. During these first 15 minutes, the children will also be divided into groups. There will be 3 groups in total, all with an approximately even amount of children in them. An even distribution based on age or math level is not needed.

Then, we move on to the experiment. During this, each group will have 10 minutes in which they will play with the website on the digiboard. When the 10 minutes start, the website is started up and the intro video is played. The children will watch the introduction video and then start playing the levels in the correct order. Whenever there is a question, they are encouraged to search for an answer together before asking the teacher / experimenter for a solution or hints. After the 10 minutes is over, the group of children switches and the experiment gets repeated. This is done once for all groups, so a total of 3 times. When one group is busy with the experiment, the other two groups will (ideally) be in a different room working on other schoolwork (possibly also math?)

In the last 15 minutes, a group discussion will be held with all children present. Here, we can ask the opinions of children and possible ways for improvement. We can also ask about the comparison between our "fun" way of learning and the regular way of learning that they do in schools. Lastly, we want to know whether they liked the website or would change anything about it.

During the whole experiment, it is important to note down all the questions that children have and the points at which the children get stuck. These things will help us find ways in which to improve our website and make it easier to use. The experimenter must also pay close attention to whether the children find it too easy and get easily distracted, or find it too difficult and ask too many questions.

We do this experiment for a number of reasons. First of all, we want to know if our website is engaging enough for young children and if they like working with it. We believe that by adding small stories in between it grabs childrens attention and they want to help the animals in need. Secondly, we want to know if the levels are not too difficult. We based the level design on the natural learning process of children in schools. We think this will mean that the levels are proper support to the regular curriculum and will be neither too easy or too difficult. Lastly, we want to know if there are enough explanation videos on the website and if it is clear enough. This is a very important question, since if the website is too difficult to navigate, then children will not be able to use it without the help of a teacher or guardian.

We believe that with the current testplan, we will be able to answer all the questions named above and we will be able to optimally fine tune our website to match the needs of our target group best.

Project Plan

In order to efficiently work on this project, a project plan was made. First, important topics and an outline of our project was written down. After that, a general planning was made with a timeframe of when what part needed to be finished on the website. Lastly, these broad tasks were divided into subtasks and each task was assigned to a group member. In the end, the tasks had more overlap than what is displayed in the planning made at the beginning of the project, but all the deliverables were finished and handed in on time.

Subjects: Child psychology, learning, image processing, software development.

Objectives: Create software to help children learn

Users: Children (of parents that want to provide a playful learning app)

State-of-the art: Alternative apps that help children either count, draw or learn colors individually. Not in a combined way, we feel the combination might improve the way to learn these things. Additionally, we hypothesize that explaining problems via a childs own drawn elements could improve their understanding.

Approach: Make up a model for how the software should work, make software in which one can draw, program software that can recognize multiple drawn objects/shapes, implement everything in a working framework according to the model.

Milestones: Drawing software, working framework, Working object recognition, implementation in task framework

Deliverables: peer review, wiki, final presentation, the software, the website
