The barrier is in the task, so that's where the support goes
CAD has too many steps to hold in your head. SchoolCAD puts one step on the screen at a time, checks it, and lets the support fade as students get more confident. It's there for every student who needs it, without a separate worksheet.
More students need adjustments than ever
of Australian students now receive an adjustment for disability at school, up from 18% in 2015.1
growth is at the substantial and extensive levels, which include continuous one-to-one support.1
No school can meet that growth with aides alone. The research points towards making everyday teaching accessible from the start, rather than adding adjustments afterwards. Breaking a task into steps is one of the practices schools use at the quality differentiated teaching level of the NCCD.
Learning the software gets in the way of learning to design
Students are learning a complex program and solving a design problem at the same time. Teachers in one interview study described how students' effort goes into handling the software.2
“There are so many steps when you model an object.”
A technology teacher, interviewed by Brink, Kilbrink and Gericke (2023, p. 969)2What scaffolding looks like in SchoolCAD
Each feature answers a barrier researchers have observed when students learn CAD.
| Barrier | What SchoolCAD does | Status |
|---|---|---|
| Too many steps to remember | One step on screen at a time, with a checklist that ticks itself off. Losing your place doesn't mean starting again. | Live |
| A screen full of tools you don't need yet | The tool for the current step is highlighted, so students know where to look. | Live |
| Not knowing whether it's right | Each step checks the student's geometry and says what to fix, such as a size that's off. | Live |
| Getting stuck and waiting | Show me models the step as a worked example the student can open and inspect. | Live |
| Support that never goes away | The Guide steps down from Full to Hints to Off, so students move towards independence. | Live |
| Reaching the end at all | Quick design lets every student finish a makeable version of the set project. | Live |
| Heavy reading load | Short instructions beside the highlighted tool. Steps read aloud. | Read-aloud planned |
| Designs that look right but can't be made | Live design checks before export in Quick design; a printability check in the Part Studio. | Part Studio check planned |
Designed with different learners in mind
Many students with ADHD, autism and dyslexia are strong visual and spatial thinkers. SchoolCAD aims to lower the memory and reading load that gets in their way.
Attention and working memory
For many students with ADHD, the hardest part of CAD is holding a long sequence in mind while the screen is full of options. Researchers studying CAD in special-education settings recommended designing for users who find complex task sequences hard to remember, and building tutorials into the software.3 Self-management checklists are also among the best-supported classroom strategies for ADHD.5
Predictability
Teachers in one study described software problems as very disruptive for students who rely on routine.4 SchoolCAD keeps the same layout in every lesson and each step says what will happen before it happens. Predictability is what makes the task possible for many autistic students, and it helps everyone else too.
Reading load
CAD tutorials are usually walls of text or fast videos. Dyslexic design students benefit from less text, not less challenge.6 SchoolCAD keeps instructions short and points to the tool on screen. Students still sketch, dimension, constrain and extrude as they would in professional CAD.
Spatial skills can be taught
Spatial thinking predicts success in STEM, and a meta-analysis of training studies found the gains last and transfer to new tasks.8 CAD can build those skills, provided the interface doesn't block students first. Computer-based scaffolding has a well-documented positive effect on STEM learning.7
Our commitments
- Every accessibility and scaffolding feature stays free. A student who needs support should never depend on a faculty budget.
- We say SchoolCAD is designed from the research. We will only say it improves outcomes once our own school pilots show it.
- We use the language students and families prefer, and describe barriers in tasks, not deficits in students.
