# Learning Paths in Intro Mechanics: free sample

*Creative Data Lab · 8 of 45 records from batch-001*

Learning paths through introductory mechanics. Each record is a problem, one or two realistic wrong attempts
tagged with a documented misconception, Socratic tutor feedback, and a correct worked solution.

This is a **free sample** so you can check the schema and quality. The full dataset is
[creativedatalab/physics-v1](https://huggingface.co/datasets/creativedatalab/physics-v1) (US$149 per organization, instant access after purchase at
[creative-data-lab-production.up.railway.app](https://creative-data-lab-production.up.railway.app/#datasets)).

## Load it

```python
from datasets import load_dataset

records    = load_dataset("creativedatalab/physics-v1-sample", "master")       # full records (default)
sft        = load_dataset("creativedatalab/physics-v1-sample", "sft")          # problem -> worked solution
tutor      = load_dataset("creativedatalab/physics-v1-sample", "tutor")        # problem + wrong attempt -> guiding question
preference = load_dataset("creativedatalab/physics-v1-sample", "preference")   # chosen / rejected pairs
steps      = load_dataset("creativedatalab/physics-v1-sample", "step_labels")  # per-step labels, first error marked
```

## How it was made

- **Ground truth is computed by code.** Every problem comes from a parameterised template; the correct answer
  and each misconception's wrong answer are computed with sympy, never by a language model.
- **Text is written by an open-weight model**: `mlx-community/Qwen2.5-32B-Instruct-4bit` (Apache 2.0), which writes problem wording,
  student attempts, feedback and solution steps around the computed values.
- **Every record passed automated checks**: answer matches truth within 1%; each wrong attempt lands exactly on its
  misconception's predicted answer; feedback does not leak the answer; all arithmetic in the text recomputes;
  no LaTeX or formatting debris; no duplicate problems.
- **Human review**: 0 of 53 records reviewed so far.

Batch yield: 53 of 56 problems kept (45 on the first try).

## Record schema (master)

`id`, `split`, `topic`, `concept_id`, `prereqs`, `rung` (R1 intuition → R5 transfer), `difficulty`,
`problem` (template, params, text, options), `ground_truth` (answer, unit, tolerance), `attempts`
(misconception_id, text, final_answer), `feedback`, `solution` (steps, final_answer), `provenance`
(generator, template version, seed, check results, human review).

## Step labels: how to read them

Correct solutions are labelled +1 at every step. For misconception attempts, the first step that reaches the
misconception's wrong answer, and every step after it, are labelled -1. Earlier steps are `null`: they are not
verified either way.

## Limitations

- Sample batch: 11 of 22 planned concepts, 45 training records.
- Multiple-choice stems are template-written, so wording repeats across records of the same template.
- Physics is checked by code; pedagogy (realism of attempts, quality of feedback) relies on human review.
