1 Amruth N. Kumar, Ramapo College of New Jersey, Mahwah, NJ, 07430, [email protected] Abstract  Using dynamic memory has been a source of frustration for Computer Science and Engineering students programming in C++. We designed a tutor to help students understand dynamic memory and avoid the pitfalls of using it. The tutor automatically generates problems on dynamic memory usage, and provides ...

We describe a programming tutor framework that consists of two configurable components, a guided-planning component and an assisted-coding component that offers task relevant automatically-generated hints on demand to students. We evaluate the effectiveness of the new integrated planning and coding environment by comparing it to three other tutor conditions: planning-only, coding-only, and plan...

This paper presents a method for computer aided tutor evaluation. The method is based on Bayesian Networks used for organizing the collected data about tutors and for enabling accurate estimations and predictions about future tutor behavior. The model provides indications about each tutor’s strengths and weaknesses, which enables the evaluator to exploit strengths to the benefit of the Universi...

We propose a decision-theoretic architecture for selecting tutorial discourse actions. DT Tutor, an action selection engine which embodies our approach, uses a dynamic decision network to consider the tutor’s objectives and uncertain beliefs in adapting to the changing tutorial state. It predicts the effects of the tutor’s discourse actions on the tutorial state, including the student’s interna...

An exploration environment and tutoring strategies were developed for the first few hours of learning the programming language LISP. In this environment, the amount of exploratory and receptive learningcan be systematically manipulated. In an experimental studywith three different learning conditions, learning in a basic exploration environment (without an automated tutor) was compared to learn...

Like humans, songbirds learn vocal sounds from "tutors" during a sensitive period of development. Vocal learning in songbirds therefore provides a powerful model system for investigating neural mechanisms by which memories of learned vocal sounds are stored. This study examined whether NCM (caudo-medial nidopallium), a region of higher level auditory cortex in songbirds, serves as a locus where...

Acoustic experience critically influences auditory cortical development, as well as emergence of highly selective auditory neurons in the songbird sensorimotor circuit. In adult zebra finches, these ‘song selective’ neurons respond better to the bird’s own song (BOS) than to songs of other conspecifics. Birds learn their songs by memorizing a tutor’s song, and then matching auditory feedback of...

When a child learns to read, the learning process can be enhanced by significant reading practice with individual support from a tutor. But in reality, the availability of teachers or clinicians is limited, so the additional use of a fully automated reading tutor would be beneficial for the child. This paper discusses our efforts to develop an automated reading tutor for Dutch. First, the dedic...
