App Inventor Pre-Advanced

Practice Engineering process to design, create, program, and deploy an actual mobile game.
This is where we will strengthen your overall game design. How do you make a splash screen? How do you manage portrait and landscape compositions? How do you manage sound effects and game music? This level will focus on how to make the details of your games even better. Whether it’s the game controller, animation effects or unique features that you want to add to your game, we’ll figure it out together.

Frequently Asked

The best age to start learning to program can be as young as 3 years old. This is the best age to expose your child to the basic concepts of computing. When they gradually grow into their teenage years, our coding and game design projects can then spark creativity, logical thinking and individuality within them. As Preface has curriculums perfectly designed for each age group, it’s never too early or too late for your child to step into the coding adventure.
First things first, coding is satisfying and fun! Once you get past the thought that coding is too complicated, given the right instructions, you can enjoy the exhilarating joy of coding your own creations. When kids learn how to code, they learn how to talk to computers. They get to break down complex ideas and arrange them in a logical way. People who can clearly analyze and communicate complex ideas in simple terms tend to be more successful in all walks of life. Programming challenges also help children develop resilience. When kids debug their own code, they develop the ability to bounce back from failure, and see failure as a learning opportunity. What’s more important is that coding trains up their technical mindset to prepare for the digital economy and the tech-driven future. By turning from a passive tech consumer, to a proactive creator, kids with coding knowledge look at the world in a different way, and who knows, maybe it even opens pathways for their future lucrative careers.
You don’t need any prior coding experience to start learning. We have courses for each experience level, from complete novice to seasoned tinkerer. At Preface, we provide a curriculum that’s just right for your kid, by considering their learning goals and preferences. If you already know the fundamentals, you can choose to skip a module by doing an assessment and interview with us.
Each learner’s curriculum is personalised based on their performance and feedback stored in our A.I. system. The MIT-influenced curriculum is designed in a way that our instructors can tweak the teaching materials to make targeted improvements and to make it more fitting to your kid’s appetite and interests. Coding is not just about the hard tech skills, but also the maker spirit — creating something impactful from scratch. Check out this demo video where our students applied their technical skills for Warner music, and created a fun animated music video. See what they have to say.

Our instructors are all battle-tested with field and academic experiences. Their background ranges from primary school teachers, software engineers, Ph.D. educators, and even lawyers.

All of them have to pass our 4-step recruitment process; from video screening, interview, curriculum-based assessment, to finally a live teaching demo. Such a strict process is to ensure that we only select the top 1.5% of instructors, which makes our learning experience the top in the industry.

Learn more aboutPreface’s difference.

Upon graduating from our coding programs or boot camps, your child will receive a certificate of completion with their name and graduation date on it.

You’ll attend a Learning Consultation, which showcases the projects your kids have done and comments from our instructors. This will be arranged at a later stage after you’ve signed up for a class.

Besides, we use scaffolding to break up learning into chunks. Students will do projects with increasing difficulty, so that our instructor can assess and ensure they have a strong understanding of the concepts before moving forward to the next.

Yes, please do. In case there’s any concern about bringing your own device, feel free to talk to our Learning Support team to work out an arrangement. For ScratchJr courses, please bring an iPad or a Tablet. For Scratch, App Inventor and any other courses, please bring a laptop. Both Mac and Windows work as long as they can be connected to the internet.
To ensure your safety, classes will be cancelled for Typhoon 8 or above, or if a black rainstorm signal or above is issued or expected to be issued 2 hours before classes start! Be sure to check the weather forecast before you head out
Just pass us your doctor certificate and we’ll arrange a make-up session for you. You can hop into another available session and we’ll try our best to accommodate.
