Taxonomy-Aligned-Conversational-Tutor/TACTBench-Samples

TACTBench Demonstration Samples

This repository contains five full-context demonstration examples from TACTBench. It does not contain the TACT training set or the remaining hidden TACTBench evaluation set. The samples use the same full-history representation as the benchmark evaluation and illustrate direct correction, error explanation, guided revision, clarification checking, affective feedback, and retry elicitation.

Data

• —data/demo.jsonl: five complete benchmark contexts selected from five distinct tutoring conversations.
• —Each row contains the full visible dialogue history before the target teacher turn, the reference teacher response, and its tutor-strategy label or labels.

These rows are demonstration examples and must not be included in future hidden benchmark scoring. Historical paper results were computed on the original 78-item benchmark before these examples were released.

Schema

• —sample_id: stable identifier for this demonstration release.
• —source_item_id: provenance identifier in the internal benchmark.
• —split: always demo.
• —context_scope: always full_history.
• —history_variant: always full_context, matching the paper evaluation.
• —full_history_turn_count: number of visible dialogue turns before the target.
• —dialogue_history: ordered teacher and student turns.
• —reference_teacher_response: the authentic next teacher turn.
• —teacher_taxonomy_labels: pedagogical function labels for the response.
• —source_full_context_word_count: descriptive word count across the complete visible dialogue history and reference response.

Source and Terms

The dialogue excerpts are derived from the Teacher-Student Chatroom Corpus version 2 (TSCC v2). TSCC is distributed by the University of Cambridge under its own user agreement for non-commercial research and educational use. This sample repository does not grant rights to the complete TSCC corpus.
