Logistic Knowledge Tracing: A Constrained Framework for Learner Modeling

نویسندگان

چکیده

Adaptive learning technology solutions often use a learner model to trace and make pedagogical decisions. The present research introduces formalized methodology for specifying models, logistic knowledge tracing (LKT), that consolidates many extant modeling methods. strength of LKT is the specification symbolic notation system alternative regression models powerful enough specify in literature new models. To demonstrate generality LKT, we fit 12 some variants well-known newly devised, six datasets. results indicated no single was best all cases, further justifying broad approach considers multiple features context. We introduce stand student-level intercepts argue be maximally applicable, needs adapt student differences. our comparisons show general importance recent datasets, with special terms memory datasets involving fact learning.

Towards Modeling Chunks in a Knowledge Tracing Framework for Students' Deep Learning

Traditional Knowledge Tracing, which traces students’ knowledge of each decomposed individual skill, has been a popular student model for adaptive tutoring. Unfortunately, such a model fails to model complex skill practices where simple decompositions cannot capture potential additional skills that underlie the context as a whole constituting an interconnected chunk. In this work, we propose a ...

A Data-Driven Framework of Modeling Skill Combinations for Deeper Knowledge Tracing

This paper explores the problem of modeling student knowledge in complex learning activities where multiple skills are required at the same time and combinations of skills might carry extra specific knowledge. We argue that in such cases mastery should be asserted only when a student can fluently apply skills in combination with other skills. We propose a data-driven framework to model skill co...

A Framework for distributed knowledge management in autonomous logistic processes

The trends and recent changes in logistics lead to complex and partially conflicting requirements on logistic planning and control systems. Due to the lack of efficiency of currently available strategies and methodologies, a new paradigm for logistics planning and control is required. An emerging approach is the analysis and design of autonomous logistic processes. Agents represent a modern app...

an investigation about the appropriate stochastic modeling framework for agricultural insurance pricing

با توجه به اینکه بیمه محصولات کشاورزی در ایران بیشتر جنبه ای حمایتی دارد و خسارات گزارش شده عموما بیش از حق بیمه های دریافت شده است، در این پایان نامه به جهت تعیین قیمت بیمه محصولات کشاورزی (گندم دیم) از فرآیندهای نوفه شلیک به عنوان مدلی مناسب استفاده شده است. بر اساس داده های صندوق بیمه کشاورزی از خسارات اعلام شده در سال زراعی 1388-1389 گندم دیم، در این پایان نامه حق بیمه خالص و ناخالص این محص...

A Framework for Learner Modelling

This paper presents a comprehensive conceptual framework and notation for learner modelling in intelligent tutoring systems. The framework is based upon the computational distinction between behaviour, behavioural knowledge, and conceptual knowledge (in a 'vertical' dimension) and between the system, the learner, and the system's representation of the learner (in a 'horizontal' dimension). All ...
