We discuss the development of Kelvi, an open source web-based dictionary and morphological parser designed to aid Tamil learners in developing their literacy skills. 
Tamil is an agglutinative language and heavily suffixal. Existing Tamil dictionaries only carry stems, not conjugated or inflected forms, and for a beginner learner of the language, isolating the stem in an unfamiliar word can be very challenging. 
Kelvi provides 1) the stem of any input word alongside its definition, and 2) non-technical descriptions of any suffixes that are part of this input, so that learners will gradually start to recognize these suffixes and be able to understand and produce new Tamil words themselves. 
In detailing our process of collaborative research, user interviews, suffix database creation, and error analysis, we also hope to show that Kelvi can be adapted for other languages and has the potential to be a useful pedagogical aid for learner literacy development, especially for agglutinative and/or polysynthetic languages which tend to be otherwise underserved in the mainstream.

Kelvi: A "Pedagogical" Morphological Parser to Support Tamil Literacy

workshop paper

It is my great pleasure and honor to welcome you to the 64th Annual Meeting of the Association for Computational Linguistics (ACL 2026), held in San Diego, California, USA, July 2–7, 2026. ACL 2026 continues our fields tradition of excellence in scholarship, innovation, and inclusivity, and I am deeply grateful to the many volunteers who have worked tirelessly to bring this event to life.

It is exciting to see the many developments in the field reflected at our conference, such as the advancement of large language models (born out of our community) into many application directions. This is not without challenges, partly due to unsolved problems, and partly due to misuse of the technology. All this is reflected well at ACL 2026. The conference also reflects that the field is not only about advancing technology, but also the science of fundamentally understanding language and how it is use by many different speaker communities. <br>

Automatic question generation with large language models has advanced rapidly, yet producing assessment-ready items, complete with mark schemes and expected answers, remains challenging, especially when generation must reliably target higher-order cognitive levels in Bloom's Taxonomy. We propose a multi-agent, multi-stage framework that generates structured assessment tuples for both short-answer questions (SAQs) and scenario-based questions (SBQs), combining Bloom-specialized generation agents with staged decomposition and automated verification. We further introduce a rubric-guided LLM-as-a-judge evaluation framework with Bloom-specific alignment metrics. Experiments on university-level AI course material across five generation pipelines show that prompt-level Bloom conditioning alone is insufficient to reliably achieve cognitive control. In contrast, our structured approach yields consistent and notable improvements in alignment, mark scheme quality, and output yield, particularly for higher-order Bloom levels over baseline pipelines.

From Questions to Assessment Tuples: A Multi-Agent Framework with Bloom-Specialized Agents and Automated Verification

We investigate the predictive power of keystroke logging data for automated essay scoring using the newly collected PISA FLA writing process dataset. Based on 3,882 writing sessions, we extract a comprehensive set of keystroke-based process features, including temporal measures, pause and burst patterns, deletion behavior, production efficiency, and navigation activity and evaluate their ability to predict holistic essay scores on a 0–5 scale. We specifically compare process-feature-based models with content-based scoring approaches trained on data written with and without the help of an AI chatbot, and investigate how predictive power evolves over the course of a writing session by training models at multiple time thresholds.
Our analysis reveals that keystroke features provide genuine early predictive signal, capturing aspects of writing fluency and revision behavior that distinguish writers before their texts are long enough to score conventionally. 
Additionally, our results suggest that process-based scoring is a viable complement to product-based approaches, with promise for formative, real-time feedback during writing.

KEYSCORE — Keystroke-enhanced Automated Essay Scoring

We introduce FDE-Arg, a new dataset of argumentative student essays in German. We use two Llama models of different sizes to label sentence-level content zones both in FDE-Arg and in an existing dataset of source-dependent argumentative essays. We investigate three approaches for improving model performance: a) Incorporating targeted task information into the prompt text; b) few-shot prompting with up to 10 examples selected on the basis of similarity with the target instance; and c) parameter-efficient finetuning. While the finetuning approach has not been shown to be successful, both incorporating additional information in the prompts and similarity-based few-shot prompting have produced highly promising performance gains compared to the baseline.

Fine-Grained Content Zone Prediction in German Argumentative Essays Using LLMs

This paper addresses the problem of fine-grained error classification in stepwise algebraic problem solving, with the objective of enabling accurate and timely feedback in large-scale educational environments. Using authentic student response data, we compare a carefully engineered rule-based baseline with large language models (LLMs) in zero-shot and few-shot configurations, as well as multistep LLM-based approaches. We further consider hybrid architectures that combine symbolic computation with LLM inferential processes, with particular emphasis on enhancing the robustness and faithfulness of intermediate representations and mitigating error propagation across successive stages of the computational pipeline. Our empirical results indicate that, although the baseline model delivers strong and reliable performance for narrowly defined error categories, structured multi-step approaches improve performance relative to single-step methods by achieving superior precision, F1 scores, and overall accuracy.

Russian grammar correction models can improve
on aggregate benchmarks
while getting worse at specific grammar rules.
We show this through per-rule evaluation
on a diagnostic benchmark of 48 prescriptive rules:
finetuning on synthetic data improves overall F$_{0.5}$
while driving subordinate-clause comma accuracy
from 14\% to 1\%.
The suppression is invisible under corpus-level metrics
and undetectable with existing coarse, corpus-specific tagsets;
it is recoverable only when diagnosed at rule granularity.
To enable this analysis,
we develop a 98-category error taxonomy
grounded in Rozental's reference grammar
and SyntErr, an open-source synthetic data generator
whose per-rule distribution is an explicit parameter,
designed to support arbitrary rule sets and languages.
Finetuning eight open models (0.8B--12B)
on 39K synthetic examples
yields up to 75.3 F$_{0.5}$,
approaching frontier API models
with models small enough to run on device.
We release the taxonomy, generator,
per-rule evaluation data, and all training artifacts.

What Aggregate Scores Hide: Per-Rule Evaluation of Russian Grammatical Error Correction

This paper looks at the impact of annotators sharing a language background with learners when annotating learner data using the Universal Dependencies (UD) framework. We perform a study comparing annotations by two different annotators working on sets of L2 Swedish sentences (learner sentences and target corrections) from the Swedish Learner Language corpus (SweLL) written by learners for whom French is a main writing language. The annotators are both L2 speakers of Swedish but have different knowledge of French: one is a native French speaker and the other has no knowledge of French. We find high annotator agreement, which may indicate an non-significant impact, though we qualitatively observe an advantage in sharing language background.

Automated Writing Evaluation (AWE) platforms have become common, but a significant gap remains between automated assessment and expert human feedback. We address this gap by introducing a supervised learning method that uses a multi-component student writing profile (comprising estimated CEFR levels, grammatical error rates, and vocabulary distribution) to align AI scoring with expert human judgments. In the context of an online essay-writing platform for second language learners of English, our model achieves a 36% reduction in RMSE for holistic essay scoring and an 84% improvement in similarity to human-expert annotation of grammatical errors compared to automarker scores (26% and 57% improvement from the best-performing comparable earlier work, by Zaidi et al. (2019) . Furthermore, we demonstrate that the model can predict a student's final submission profile (CEFR level and grammatical error rate) from earlier drafts and that predictions generalize to a subsequent task, offering new possibilities for automated curriculum planning. Finally, we introduce a visualization tool that provides educators with clear expert-aligned longitudinal views of student development.

When programming students encounter errors in their code, compiler messages or static analysis output often provide limited guidance, particularly for novice programmers. Personalized feedback from instructors can be effective but does not scale well. Recent advances in large language models (LLMs) enable automated feedback generation at scale.
This study examines whether LLM-generated feedback with different levels of guidance is associated with differences in students' problem-solving behavior. We analyze effects on time to solution and number of attempts, and examine whether these effects differ by programming experience. We design three feedback types and compare them to a baseline in which students receive only compiler error messages. Results from an online programming course show that LLM-generated feedback is associated with faster time to solution compared to the no-feedback baseline, with less guided feedback showing slightly stronger effects. 
Overall, the findings suggest that feedback structure plays an important role in how students progress toward correct solutions and motivate further work on adaptive feedback designs and longer-term learning outcomes.

The Effects of Structured LLM-Generated Feedback on Programming Assignment Performance

This paper investigates whether automated short answer grading can reliably support teachers when marking conceptual physics responses in settings with limited labelled data. Using free-text responses derived from Force Concept Inventory-style questions, the study shows that incorporating subject-specific knowledge improves grading consistency, particularly in early deployment scenarios. The system reduces grading errors and provides more reliable agreement with reference judgement's, especially for more challenging questions. These results suggest that automated grading can assist teachers by supporting marking decisions and prioritizing responses for review, while still requiring human oversight.

Domain-Adaptive Pre-training for Automated Short Answer Grading in Conceptual Physics: Reliability, Question-Level Analysis, and Error Reduction

Large audio language models (LALMs) integrate audio representations with large language models to enable unified understanding of spoken content. Their capabilities have been increasingly investigated across several benchmarks; however, the examination of their use in rating L2 speech is still in its infancy. This study explores the abilities of LALMs in scoring three L2 speech global dimensions: foreign accentedness, comprehensibility, and intelligibility. Ninety audio samples produced by L2 speakers were rated by ten native speaker raters as well as five LALM models. Model performance was evaluated against the human composite mean using Pearson r, Spearman p, mean absolute error (MAE), and systematic bias, with the human leave-one-out correlation (r = .46-.73 across dimensions) serving as an empirical performance benchmark. The results showed that no LALM reached human-level performance on any dimension. Only one model (i.e., Gemini) achieved a significant correlation with human ratings on comprehensibility (r = .28, p < .01), while Qwen2-Audio showed modest correlation on intelligibility (r = .32, p < .01). MAE ranged from 0.75 to 3.99 for accentedness (human: 1.24), 1.35 to 3.00 for comprehensibility (human: 1.24), and 12.03 to 15.43 for intelligibility (human: 8.49). All models exhibited systematic biases, with deviations ranging from -9.31 to +13.19 points. The paper concludes with a discussion of the implications for automated L2 speech assessment.
