Block-to-Text Python Education Instruction Dataset
Overview
This dataset was created as part of an MSc Computer Science dissertation focused on supporting learners during the transition from block-based programming (such as Blockly) to text-based Python coding.
The dataset is designed for instruction tuning of lightweight language models, particularly Microsoft Phi-2, to act as an educational assistant for beginner programmers rather than a full code generator.
It prioritises clarity, age-appropriate explanations, and minimal guidance to encourage learning and problem-solving.
Educational Context
Block-based programming environments help beginners avoid syntax errors but often fail to prepare learners for real programming languages. When students move to Python, they frequently struggle with:
- Syntax rules (indentation, colons, brackets)
- Interpreting error messages
- Translating visual logic into written code
This dataset directly addresses these challenges by providing structured instructional examples that mirror common beginner mistakes and learning scenarios.
Dataset Format
The dataset is provided in JSONL (JSON Lines) format.
Each line represents one training example using an instruction-tuning structure:
{
"instruction": "...",
"input": "...",
"output": "..."
}
