NTUs: An Intelligent Tutorial System Fosters Number Concepts through Computational Scaffolding
نویسندگان
چکیده
The present article describes how scaffolding is implemented in an intelligent tutorial system call NTUs (Number Transcoding tUtorial System), and what are the results of the system tested empirically on a group of grade students in fostering their number concepts. To use NTUs. the system first analyzes a user’s errors on a number transcoding task, and the results of analysis are used to infer the user’s zone of proximal development (ZPD). A scaffolding process which was designed with inspiration from how people learn Chinese calligraphy will be provided next in the user’s ZPD. Empirical test indicates that NTUs can not only foster students ’ number concepts but also attract them to use it.

Toward a Modular Reinforcement Learning Framework for Tutorial Planning in GIFT
Intelligent tutoring systems (ITSs) are highly effective at fostering learning gains across a broad range of educational domains (VanLehn, 2011; Woolf, 2008). Tutorial planning is a critical component of ITSs, controlling how scaffolding is structured and delivered to learners. Tutorial planners operate at multiple levels, including the macro-level (e.g., selecting problems for learners to solv...
متن کاملScaffolding and Knowledge Appropriation in Online Collaborative Group Discussions
Sociocultural constructivism assumes that a learner’s capacity for intellectual growth increases with the presence of scaffolding or support during interaction. Moreover, from participating in dialogic interaction, there is appropriation of the knowledge shared and jointly created by learners which could transform individual understandings. Hence, interactions are opportunities for scaffolding ...
متن کاملSupporting Tutorial Feedback to Student Help Requests and Errors in Symbolic Differentiation
The provision of intelligent, user-adaptive, and effective feedback requires human tutors to exploit their expert knowledge about the domain of instruction, and to diagnose students’ actions through a potentially huge space of possible solutions and misconceptions. Designers and developers of intelligent tutoring systems strive to simulate good human tutors, and to replicate their reasoning and...

This paper describes a study which is part of a project whose goal is to detect students’ prior knowledge levels with respect to a target domain based solely on characteristics of the natural language interaction between students and a state-of-the-art conversational Intelligent Tutoring System (ITS). We report results on dialogues collected from two versions of the intelligent tutoring system ...
