assertion_sentence_references_student_behavior_or_work

Assertion: sentence references student behavior or work

This classifier was trained for EduBehaviors: Assertion-based schemas for auditable dialogue coding and is usable through the Python package EduBehaviors-kit. This classifier was trained on an LLM-annotated subset of teacher utterances from the TalkMoves Dataset. See the Datasets section below for more information.

Training Details

Datasets

This model's columns are assertion_sentence_references_student_behavior_or_work and split_sentence_references_student_behavior_or_work.

Base rate (share of rows labeled as True): 33.5% overall — 32.8% train, 33.5% dev, 34.7% test.

Labels and annotation

Labels were generated with LLM annotators. Krippendorff's alpha for this assertion is 0.382.

Evaluation

Results

Limitations

• Labels come from LLM annotators, not human coders. **Agreement with Krippendorff's Alpha is 0.382; this is poor.**This model's predictions and the underlying data are unreliable.
• Trained on teacher utterances only. Behaviour on student speech is untested.

How to Use

Message Structure

The model was trained on text built as:

{utterance}

The utterance is passed through as-is.

Running instructions

pip install setfit

from setfit import SetFitModel

model = SetFitModel.from_pretrained("StanfordSCALE/assertion_sentence_references_student_behavior_or_work")

text = 'Go'
model.predict([text])        # -> array([1]) when the assertion holds
model.predict_proba([text])  # -> [[P(no), P(yes)]]
