• Abstract: This paper presents a web-based JavaScript editor designed to help children aged 8-10 transition from block-based to text-based programming. The system introduces a simplified domain-specific language (DSL) focused on visual art, combining authentic JavaScript syntax with immediate, creative visual feedback. A four-week pilot study (N = 15) demonstrated significant improvements in computational thinking skills (mean CTCI gain of +10.9, p < 0.001), along with a 70% reduction in syntax errors. Participants advanced from basic drawing functions to sophisticated algorithmic designs using loops, conditionals, and animations. By integrating constructionist principles with a visual-first DSL, this research contributes a validated pedagogical framework for easing the block-to-text transition in K-12 computer science education. The system encourages creativity, self-correction, and sustained engagement, offering educators a practical, scalable tool for introducing authentic coding to young learners.

  Teaching Computer Science (CS) by having students write programs by hand on paper has key pedagogical advantages. However, a key obstacle is the current lack of teaching methods and support software for working with and running handwritten programs. Our approach integrates two innovative methods. The first combines OCR with an indentation recognition module and a language model designed for post-OCR error correction without introducing hallucinations.

LASP is inherently amenable to including, during training, virtual classes, i.e. class names for which no visual samples are available. LASP matches and surpasses, for the first time, the accuracy on novel classes obtained by hand-crafted prompts and CLIP for 8 out of 11 test datasets.
