Bridging strategy gaps in programming: the role of visual scaffolding for learners with low cognitive ability

Research from Educational Technology Research and Development (International) explores the impact of visual scaffolding on programming strategies for learners with varying cognitive abilities. The study investigates how visual programming tools can mitigate cognitive demands in programming education, particularly for individuals with lower executive function. A small-scale experiment involving 32 adults used eye-tracking and cognitive assessments to observe programming processes with and without visual support.

Why it matters

As programming skills become increasingly vital across sectors, addressing cognitive barriers to learning is crucial for workforce development and talent pipeline expansion. Understanding how visual aids and cognitive abilities interact in learning environments can inform more effective pedagogical approaches and tool development, ultimately enhancing digital literacy and technical proficiency at scale.

Key insights

• Programming education presents cognitive challenges for learners, particularly in textual environments.
• Visual programming tools aim to alleviate the cognitive load associated with programming.
• Learners' executive function (EF) may influence programming processes and strategies.
• The study examined the influence of visual scaffolding on programming strategies across different EF levels.
• An eye-tracker was employed to analyze cognitive processes during programming tasks.
• A small sample size of 32 adult participants was used, divided into experimental and control groups.
