• Authors: Tim Steuer, Anna Filighera, Tobias Meuser and Christoph Rensing
• Abstract summary: Posing questions about what learners have read is a well-established way of fostering their text comprehension. Many textbooks lack self-assessment questions because authoring them is time-consuming and expensive. This paper introduces a novel pedagogically meaningful content selection mechanism to find question-worthy sentences and answers in arbitrary textbook contents.

• Abstract: Most learners fail to develop deep text comprehension when reading textbooks passively. Posing questions about what learners have read is a well-established way of fostering their text comprehension. However, many textbooks lack self-assessment questions because authoring them is timeconsuming and expensive. Automatic question generators may alleviate this scarcity by generating sound pedagogical questions. However, generating questions automatically poses linguistic and pedagogical challenges. What should we ask? And, how do we phrase the question automatically? We address those challenges with an automatic question generator grounded in learning theory. The paper introduces a novel pedagogically meaningful content selection mechanism to find question-worthy sentences and answers in arbitrary textbook contents. We conducted an empirical evaluation study with educational experts, annotating 150 generated questions in six different domains. Results indicate a high linguistic quality of the generated questions. Furthermore, the evaluation results imply that the majority of the generated questions inquire central information related to the given text and may foster text comprehension in specific learning scenarios.

  We present a question generation framework with controllable comprehension types for assessing and improving machine reading comprehension models. We first frame the comprehension type of questions based on a hierarchical skill-based schema, then formulate $textttSkillQG$ as a skill-conditioned question generator. Empirical results demonstrate that $textttSkillQG$ outperforms baselines in terms of quality, relevance, and skill-controllability.
