When a pedagogical agent system aims to provide students with interactive help, it needs to know what knowledge the student has and what goals the student is currently trying to achieve. That is, it must do both assessment and plan recognition. These modeling tasks involve a high level of uncertainty when students are allowed to follow various lines of reasoning and are not required to show all...

Offering a new course on user-interface design presents several problems for a Computer Science department. As well as building student competency in user interface design and user interface evaluation, the course must give timely feedback to students while ensuring that staff and student workload remains manageable. We developed a course that uses a novel system of tutorials and group work to ...

Teachers’ implementation of technology-enhanced student-centered learning environments (SCLEs) will be affected by their beliefs about effective practices. In order for student-centered programs to be used as intended, designers must be aware of the key issues that will shape their implementation and the beliefs teachers hold about these issues. This case study examined 15 teachers’ beliefs abo...

Because many students experience frustration during learning, it is important to develop affective strategies to support students’ coping with frustration in interactive learning environments. First, we must devise affect recognition models to detect student affect. Second, we need to determine when to intervene; these conditions are likely to be different for each student. To determine how muc...

The main objective of an Adaptive System is to adequate its relation with the user (content presentation, navigation, interface, etc.) according to a predefined but updatable model of the user that reflects his objectives, preferences, knowledge and competences [Brusilovsky, 2001], [De Bra, 2004]. For Educational Adaptive Systems, the emphasis is placed on the student knowledge in the domain ap...

It is worth considering to what degree the lot of medical students has improved since Vincent Norman reflected on his days as a student. While diet may have got better, there are clear parallels between the medical student in the first half of the last century who had to pay hospital fees and the student of today who must take out a loan to pay for tuition. In this regard I should declare my ow...

Many assigned problems in introductory physics courses require the student to formulate a system of algebraic equations that describe a physical situation. An Intelligent Tutoring System (ITS) designed to help must be able to identify which physical quantity each student variable represents, and which fundamental laws each of her equations incorporates. Many ITS’s predefine the variables ([4,2]...

This paper describes the student modeler of the GUIDON2 tutor, which understands plans by a dual search strategy. It first produces multiple predictions of student behavior by a model-driven simulation of the expert. Focused, data-driven searches then explain incongruities. By supplementing each other, these methods lead to an efficient and robust plan understander for a complex domain. 1. Basi...

background: the main purpose of medical education system is that the students achieve the highest levels of learning and professional competency. training of skilled physicians is based on three domains including educational planning, environment, and psychological situation. methods: our study is a descriptive-analysis, conducted on 119 students including medical, nursing and midwifery groups ...

Dear Editor, The relationship between the PhD supervisorand the PhD student is a complex one. Whenthis relationship is neither effective nor efficient,it may yield negative consequences, such asacademic failure (1).The intricacy of the supervisor-studentrelationship may be in part comparable to the onebetween the physician and his/her patient [see,for example (2)]. Both interactions develop ove...
