Today, we are publishing an impact report that includes some of this feedback, along with what users are saying about the impact Ada Computer Science is having.

Evaluating Ada Computer Science

Ada Computer Science is a free learning platform for computer science students and teachers. It provides high-quality, online learning materials to use in the classroom, for homework, and for revision. Our experienced team has created resources that cover every topic in the leading GCSE and A level computer science specifications.

From May to July 2024, we invited users to provide feedback via an online survey, and we got responses from 163 students and 27 teachers. To explore the feedback further, we also conducted in-depth interviews with three computer science teachers in September 2024.

How is Ada being used?

The most common ways students use Ada Computer Science — as reported by more than two thirds of respondents — is for revision and/or to complete work set by their teacher. Similarly, teachers most commonly said that they direct students to use Ada outside the classroom.

“I recommend my students use Ada Computer Science as their main textbook.” — Teacher

What is users’ experience of using Ada?

Most respondents agreed or strongly agreed that Ada is useful for learning (82%) and high quality (79%).

“Ada Computer Science has been very effective for independent revision, I like how it provides hints and pointers if you answer a question incorrectly.” — Student

Ada users were generally positive about their overall experience of the platform and using it to find the information they were looking for.

“Ada is one of the best for hitting the nail on the head. They’ve really got it in tune with the depth that exam boards want.” — Ian Robinson, computer science teacher (St Alban’s Catholic High School, UK)

What impact is Ada having?

Around half of the teachers agreed that Ada had reduced their workload and/or increased their subject knowledge. Across all respondents, teachers estimated that the average weekly time saving was 1 hour 8 minutes.

Additionally, 81% of students agreed that as a result of using Ada, they had become better at understanding computer science concepts. Other benefits were reported too, with most students agreeing that they had become better problem-solvers, for example.

“I love Ada! It is an extremely helpful resource… The content featured is very comprehensive and detailed, and the visual guides… are particularly helpful to aid my understanding.” — Student

Future developments

Since receiving this feedback, we have already released updated site navigation and new question finder designs. In 2025, we are planning improvements to the markbook (for example, giving teachers an overview of the assignments they’ve set) and to how assignments can be created.

If you’d like to read more about the findings, there’s a full report for you to download. Thank you to everyone who took the time to take part — we really value your feedback!

Supporting students through personalised learning, new resources, and new questions

We made significant improvements throughout the year to support students with exam preparation and personalised learning. We introduced over 145 new self-marking questions and updated 50 existing ones, bringing the total to more than 1000. A new type of question was also launched to help students practise writing longer responses: they label parts of a sample answer and apply a mark scheme, simulating a peer review process. You can read more about this work in the AI section below.

We updated the question finder tool with an intuitive new design. Instead of seeing ten questions at random, students can now see all the questions we have on any given topic, and can use the filters to refine their searches by qualification and difficulty level. This enables students to better personalise their revision and progress tracking

“Ada Computer Science has been very effective for my revision. I like how it provides hints and pointers if you answer a question incorrectly.”

The ‘Representation of sound’ topic received a major update, with clearer explanations, new diagrams, and improved feedback to support students as they tackle common misconceptions in sound physics. We also refreshed the ‘Representation of numbers’ topic, adding new content and interactive quizzes to support teachers in assessing students’ understanding more effectively. 

We introduced a new database scenario titled ‘Repair & Reform’, offering an entity relationship diagram, a data dictionary, and a new SQL editor and question set to help students prepare for project-based assessments. We’ve further expanded this scenario into a full project covering all stages of development, including requirements analysis and evaluation. 

April was dedicated to gearing up for the exam season, with the introduction of revision flashcards and ready-made quizzes on key topics like bitmapped graphics and sorting algorithms. We also launched a student revision challenge, which ran from April to June and attracted over 600 participants.

“Ada Computer Science is an excellent resource to help support teachers and students. The explanations are clear and relevant, and the questions help students test their knowledge and understanding in a structured way, providing links to help them reconcile any discrepancies or misunderstandings.” 

– Patrick Kennedy, Computer Science teacher

Supporting teachers  

We expanded our efforts to support new computer science teachers with the launch of a teacher mentoring programme that offers free online drop-in sessions. We also hosted a teacher training event at the Raspberry Pi Foundation office in Cambridge (as seen in the picture below), where educators saw previews of upcoming content on AI and machine learning and contributed their own questions to the platform.

AI content and AI features

We continued our focus on AI and machine learning, releasing new learning resources that explore the ethical and social implications of AI alongside the practical applications of AI and machine learning models. 

To expand the Ada platform’s features, we also made considerable progress in integrating a large language model (LLM) to mark free-text responses. Our research showed that, as of June, LLM marks matched real teachers’ marks 82% of the time. In July, we received ethics approval from the University of Cambridge to add LLM-marked questions to the Ada platform. 

Computer science education in Scotland

We made significant strides towards supporting Scottish teachers and students with resources tailored to the SQA Computing Science curriculum. From September to November last year, we piloted a new set of materials specifically designed for Scottish teachers, receiving valuable feedback that we’ve used in 2024 to develop new content. More than half of the theory content for the National 5 and Higher specifications is now available on the platform. 

Our ‘Reform & Repair’ database scenario and project align with both SQA Higher and A level standards, providing a comprehensive resource for students preparing for project-based assessments.

Looking ahead: New resources for September and beyond

We have big plans for Ada for the next 12 months. Our focus will remain on continuously improving our resources and supporting the needs of both educators and students. 

After the positive response to our ‘Repair & Reform’ database project, our content experts are planning additional practical projects to support students and teachers. The next one will be a web project that covers HTML, CSS, JavaScript, and PHP, supporting students taking SQA qualifications in Scotland or undertaking the non-examined assessment (NEA) at A level.

We’ll be working on a number of teacher-focused improvements to the platform, which you’ll also see on Ada’s sibling site, Isaac Physics. These will include an overhaul of the markbook to make it more user-friendly, and updates to the ‘Assignments’ tool so assignments better meet the needs of teachers in schools.

We’ll be welcoming the next cohort of computer science students to the STEM SMART programme in January 2025 where, in partnership with the University of Cambridge, we’ll offer free, complementary teaching and support to UK students at state schools. Applications are now open.

Thank you to every teacher and student who has given their time in the last year to share feedback about Ada Computer Science — your insights are invaluable as we work to make high-quality computer science materials easily accessible. Here’s to another fantastic year of learning and growth!

The post Ada Computer Science: A year in review appeared first on Raspberry Pi Foundation.

Recently, we had the pleasure of speaking with Isabel, a computer science teacher at Barton Peveril Sixth Form College in Eastleigh, England. She told us her fascinating journey from industry to education, along with how she is helping to make the tech space inviting to all.

From industry to the classroom: Isabel’s journey to encourage diversity in tech

Isabel’s path to working in the tech sector started with her early exposure to engineering thanks to her father’s career in telecoms.

“I find this is true for a lot of female engineers my age: you will find that their dad or their uncle was an engineer. I remember that when I made the decision to study engineering, my teachers asked me if I was sure that it was something I wanted to do.”

Isabel pursued a degree in engineering because she loved the technical aspects, and during her studies she found a passion for programming. She went to work as a software engineer in Hampshire, contributing to the development of 3G mobile phone technology.

Despite enjoying her career in tech, Isabel felt a strong pull towards teaching due to her long-standing involvement with youth groups and a desire to give back to the community.

“While I was at university in London, I took part in a scheme where we could go into local primary schools and help with their science teaching. At the time, I just thought this was my way of giving back, I hadn’t really thought of it as a career. But actually, after a while, I thought ‘I’m enjoying this programming, but I really liked helping the young kids as well’.”

The transition wasn’t easy, as Computer Science was not widely taught in schools at the time, but Isabel persevered, teaching IT and Media to her classes as well.

Once Isabel settled into her teaching role, she began thinking about how she could tackle a problem she noticed in the STEM field.

Championing diversity in tech

Having experienced first-hand what it was like to be the only woman in STEM spaces, Isabel’s commitment to diversity in technology is at the core of her teaching philosophy. She works hard to create an inclusive environment and a diversity of opportunities in her classroom, making sure girls feel encouraged to pursue careers in tech through exploring various enrichment activities.

Isabel focuses on enrichment activities that bridge the gap between academic learning and real-world application. She runs various projects and competitions, ensuring a balanced representation of girls in these initiatives, and gives her students the opportunity to participate in programs like the Industrial Cadets, Student Robotics, and Coolest Projects. 

Isabel told us that she feels these opportunities provide essential soft skills that are crucial for success in any career.

“The A level environment is so academic; it is heavily focused on working on your own on very abstract topics. Having worked in industry and knowing the need to collaborate, I found that really hard. So I’ve always made sure to do lots of projects with my students where we actually work with real engineers, do real-world projects. I believe strongly in teaching soft skills like team working, project management, and time management.”

Harnessing trusted resources

A key resource in Isabel’s teaching toolkit is the Ada Computer Science platform. She values its reliability and the timely updates to the topics, which are crucial in a rapidly evolving subject like Computer Science.

She said she encourages both her students and fellow teachers, especially those who have retrained in Computer Science, to use the platform as a resource. 

“Ada Computer Science is amazing. We know we can rely on saying to the students ‘look on Ada, the information will be correct’ because I trust the people creating the resources. And we even found ourselves as teachers double-checking things on there. We struggle to get Computer science teachers, so actually only two of us are Computer Science teachers, and the other three are Maths teachers we have trained up. To be able to say ‘if you are not sure about something, look on Ada’ is a really nice thing to have.”

The ongoing challenge and hope for the future

Despite her efforts, Isabel acknowledges that progress in getting more girls to pursue tech careers is slow. Many girls still view tech as an uninviting space and feel like they don’t belong when they find themselves as one of a few girls — if not the only one — in a class. But Isabel remains hopeful that continuous exposure and positive experiences can change these perceptions.

“I talk to students who are often the only girl in the class and they find that really hard. So, if at GCSE they are the only girl in the class, they won’t do [the subject] at A level. So, if we leave it until A level, it is almost too late. Because of this, I try as much as I can to get as many girls as possible onto my engineering enrichment projects to show them as many opportunities in engineering as possible early on.”

Her work with organisations like the UK Electronics Skills Foundation reflects her commitment to raising awareness about careers in electronics and engineering. Through her outreach and enrichment projects, Isabel educates younger students about the opportunities in these fields, hoping to inspire more girls to consider them as viable career paths.

Looking ahead

As new technology continues to be built, Isabel recognises the challenges in keeping up with rapid changes, especially with fields like artificial intelligence (AI). She stays updated through continuous learning and collaborating with her peers, and encourages her students to be adaptable and open to new developments. “The world of AI is both exciting and daunting,” she admits. “We need to prepare our students for a future that we can hardly predict.”

Isabel’s dedication to teaching, her advocacy for diversity, and her efforts to provide real-world learning opportunities make her an inspiring educator. Her commitment was recognised by the Era Foundation in 2023: Isabel was named as one of their David Clark Prize recipients. The award recognises those who “have gone above and beyond the curriculum to inspire students and showcase real-world engineering in the classroom”.

Isabel not only imparts technical knowledge — she inspires her students to believe in their potential, encouraging a new generation of diverse tech professionals.

The post Celebrating the community: Isabel appeared first on Raspberry Pi Foundation.

Our goal for the webinars was to highlight the breadth of careers within computing and to provide insights from professionals who are pursuing their own diverse and rewarding paths. Each webinar featured engaging discussions and an interactive Q&A session with learners who use our Ada Computer Science platform. The learners could ask their own questions to get firsthand knowledge and perspectives from our guest speakers.

Our guest speakers

Jess Van Brummelen is a Human–Computer Interaction Research Scientist at Niantic, the video games company behind augmented reality game Pokémon Go. After developing an interest in programming during her undergraduate degree in mechanical engineering, she went on to complete a Master’s degree and PhD in computer science at MIT.

Ashley Edwards is a Senior Research Scientist at Google DeepMind, working on reinforcement learning. She received her PhD in 2019 from Georgia Tech, spent time as an intern at Google Brain, and worked as a research scientist at Uber AI Labs.

You can read extracts from our interviews with Jess and Ashley and watch the full videos below. Teachers have contacted us to say they’ll be using the webinars for careers-focused sessions with their students. We hope you will do the same!

Please note that we have edited the extracts below to add clarity.

Jess Van Brummelen

Hi Jess. What advice would you give to a student who is thinking about a career in human–computer interaction in the gaming industry?

In terms of HCI and gaming, I’d actually recommend that you keep gaming! It’s a small part of my job but it’s really important to understand what’s fun and enjoyable in games. Not only that; gaming can be great for learning to problem-solve — there’s been all sorts of research on the positive impact of gaming.

A second thing, going back to how I felt in my mechanical engineering classes, I really felt like an ‘other’ and not someone who is the standard computer scientist or engineer. I would encourage students to pursue their dreams anyway because it’s so important to have diversity in these types of careers, especially technology, because it goes out to so many different people and it can really affect society. It’s really important that the people who make it come from many different backgrounds and cultures so we can create technology that is better for everyone.

[From Owen, a student on the livestream] What’s the most impossible idea you’ve come up with while working at Niantic?

I’m currently publishing a paper addressing the question, ‘Can we guide people without using anything visual on their phone?’ That means using audio and haptic (technology that transmits information via touch, e.g. vibrations) prompts instead. We tried out different commands where the phone said ‘turn left’ and ‘turn right’, but we really wanted to test how to guide someone more specifically in a game environment. For example, if there was a hidden object on a wall in a game that a person couldn’t see, could we guide them to that object while they’re walking? So I ran a study where I guided people to scan a statue by moving around it. Scanning is the process of using the camera on your phone to scan an object in real life, which is then reconstructed on your phone. Scanning objects can trigger other augmented reality experiences within a game. For example, you might scan a real-life box in a room and this might trigger an animation of that box opening to reveal a secret within the game. We tested a lot of different things. For example, test subjects listened to music as they were walking and when they were on the right path, the music sounded really good. But when they were off the path, it sounded terrible. So it helped them to look for the right path. Then if you were pointing the phone in the wrong direction for scanning objects, you would get warning vibrations on the phone. So we did the study and we were hoping it would improve safety. It turns out it was neutral on improving safety — I think this is because it was such a novel system. People weren’t used to using it and still bumped into things! But it did make people better at scanning the objects, which was interesting.

Ashley Edwards

Hi Ashley. Is there something you studied in school that you found to be more useful now than you ever thought it would be?

Maths! I always enjoyed doing maths, but I didn’t realise I would need it as a computer scientist. You see it popping up all the time, especially in machine learning. Having a strong knowledge of calculus and linear algebra is really helpful.

How do you train an AI model using machine learning? 

You start by asking the question, ‘What is the problem I’m trying to solve?’ Then typically you need input data and the outputs you want to achieve, so you ask two more questions, ‘What data do I want to come in?’ and ‘What do I want to come out?’ Let’s say you decide to use a supervised learning model (a category of machine learning where labelled data sets are used to train algorithms to detect patterns and predict outcomes) to predict whether a photo contains a cat. You train the model using a giant set of images with labels that say either ‘This is a cat’ or ‘This isn’t a cat’. By training the model with the images, you get to a point where your model can analyse the features of any image and predict whether it contains a cat or not.

In my field of research, I work on something called reinforcement learning, which is where you train your model through trial and error and the use of ‘rewards’. Let’s imagine we are trying to train a robot. We might write a program that tells the robot, ‘I am going to give you a reward if you take the right step forward and it’s going to be a positive reward. If you fall over, I’m going to give you a negative reward.’ So you train the robot to prioritise the right behaviours to optimise the rewards it’s getting.

[From a student] Will I still need to learn to code in the future?

I think it is going to be very different in the future, but we’ll still need to learn how to build different types of algorithms and we’re going to need to understand the concepts behind coding as well. We’ll still need to ask questions like, ‘What is it that I want to build?’ and ‘Is this actually doing the correct thing?’

Broadening access

Jess and Ashley are forging successful careers not only through a combination of smart choices, hard work, talent, and a passion for technology; they also had access to opportunities to discover their passion and receive an education in this field. Too many young people around the world still don’t have these opportunities.

That is why we provide free resources and training to help schools broaden access to computing education. For example, our free learning platform, Ada Computer Science, provides students aged 14 to 19 with high-quality computing resources and interactive questions, written by experts from our team.

What’s new on Ada?

Ada Computer Science is our online learning platform designed for teachers, students, and anyone interested in learning about computer science. If you’re teaching or studying a computer science qualification at school, you can use Ada Computer Science for classwork, homework, and revision. 

Launched last year as a partnership between us and the University of Cambridge, Ada’s comprehensive resources cover topics like algorithms, data structures, computational thinking, and cybersecurity. It also includes 1,000 self-marking questions, which both teachers and students can use to assess their knowledge and understanding. 

Throughout 2023, we continued to develop the support Ada offers. For example, we: 

• Added over 100 new questions
• Expanded code specimens to cover Java and Visual Basic as well as Python and C#
• Added an integrated way of learning about databases through writing and executing SQL
• Incorporated a beta version of an embedded Python editor with the ability to run code and compare the output with correct solutions 

A few weeks ago we launched two all-new topics about artificial intelligence (AI) and machine learning.

So far, all the content on Ada Computer Science is mapped to GCSE and A level exam boards in England, and we’ve just released new resources for the Scottish Qualification Authority’s Computer Systems area of study to support students in Scotland with their National 5 and Higher qualifications.

Who is using Ada?

Ada is being used by a wide variety of users, from at least 127 countries all across the globe. Countries where Ada is most popular include the UK, US, Canada, Australia, Brazil, India, China, Nigeria, Ghana, Kenya, China, Myanmar, and Indonesia.

Just over half of students using Ada are completing work set by their teacher. However, there are also substantial numbers of young people benefitting from using Ada for their own independent learning. So far, over half a million question attempts have been made on the platform.

How are people using Ada?

Students use Ada for a wide variety of purposes. The most common response in our survey was for revision, but students also use it to complete work set by teachers, to learn new concepts, and to check their understanding of computer science concepts.

Teachers also use Ada for a combination of their own learning, in the classroom with their students, and for setting work outside of lessons. They told us that they value Ada as a source of pre-made questions.

“I like having a bank of questions as a teacher. It’s tiring to create more. I like that I can use the finder and create questions very quickly.” — Computer science teacher, A level

“I like the structure of how it [Ada] is put together. [Resources] are really easy to find and being able to sort by exam board makes it really useful because… at A level there is a huge difference between exam boards.” — GCSE and A level teacher

What feedback are people giving about Ada?

Students and teachers alike were very positive about the quality and usefulness of Ada Computer Science. Overall, 89% of students responding to our survey agreed that Ada is useful for helping them to learn about computer science, and 93% of teachers agreed that it is high quality.

“The impact for me was just having a resource that I felt I always could trust.” — Head of Computer Science

Most teachers also reported that using Ada reduces their workload, saving an average of 3 hours per week.

“[Quizzes] are the most useful because it’s the biggest time saving…especially having them nicely self-marked as well.” — GCSE and A level computer science teacher

Even more encouragingly, Ada users report a positive impact on their knowledge, skills, and attitudes to computer science. Teachers report that, as a result of using Ada, their computer science subject knowledge and their confidence in teaching has increased, and report similar benefits for their students.

“They can easily…recap and see how they’ve been getting on with the different topic areas.” — GCSE and A level computer science teacher

“I see they’re answering the questions and learning things without really realising it, which is quite nice.” — GCSE and A level computer science teacher

How do we use people’s feedback to improve the platform?

Our content team is made up of experienced computer science teachers, and we’re always updating the site in response to feedback from the teachers and students who use our resources. We receive feedback through support tickets, and we have a monthly meeting where we comb through every wrong answer that students entered to help us identify new misconceptions. We then use all of this to improve the content, and the feedback we give students on the platform.

We’d love to hear from you

We’ll be conducting another round of surveys later this year, so when you see the link, please fill in the form. In the meantime, if you have any feedback or suggestions for improvements, please get in touch.

And if you’ve not signed up to Ada yet as a teacher or student, you can take a look right now over at adacomputerscience.org

A partnership between the Raspberry Pi Foundation and the University of Cambridge, Ada Computer Science offers comprehensive resources covering everything from algorithms and data structures to computational thinking and cybersecurity. It also has nearly 1000 rigorously researched and automatically marked interactive questions to test your understanding. Ada Computer Science is improving all the time, with new content developed in response to user feedback and the latest research. Whatever your interest in computer science, Ada is the place for you.

If you’re teaching or studying a computer science qualification at school, you can use Ada Computer Science for classwork, homework, and revision. Computer science teachers can select questions to set as assignments for their students and have the assignments marked directly. The assignment results help you and your students understand how well they have grasped the key concepts and identify areas where they would benefit from further tuition. Students can learn with the help of written materials, concept illustrations, and videos, and they can test their knowledge and prepare for exams.

A comprehensive resource for computing education

Ada Computer Science builds on work we’ve done to support the English school system as part of the National Centre for Computing Education, funded by the Department for Education.

The topics on the website map to exam board specifications for England’s Computer Science GCSE and A level, and will map to other curricula in the future.

In addition, we want to make it easy for educators and learners across the globe to use Ada Computer Science. That’s why each topic is aligned to our own comprehensive taxonomy of computing content for education, which is independent of the English curriculum, and organises the content into 11 strands, including programming, computing systems, data and information, artificial intelligence, creating media, and societal impacts of digital technology.
