Nowadays, Problem-Based Learning (PBL for short) is a popular teaching strategy for teachers. In the PBL environment students can learn how to solve the real life problems by discussing with their teammates and develo...

One-on-one educational computing refers to I student I computing device, which means every student in a group uses a digital learning device. In this paper, we present a model of student question generation called AGQ, which stands for "asking a good question," supported by one-on-one educational computing in the classroom settings. AGQ is designed for engaging students in a challenging learning activity that potentially involves higher-level cognitive processing operations. We shall describe the general design of AGQ, called Product Evolution, and that the current version is a variation of it.

Integration of version and access control of XML documents has the benefit of regulating access to rapidly growing archives of XML documents. Versioned XML documents provide us with valuable informations on dependencies between document nodes, but at the same time presenting the risk of undesirable data disclosure. In this paper we introduce the notion of relevancy-based access control, which realizes protection of versioned XML documents by various types of relevancy, such as version dependencies, schema similarities and temporal proximity. We define a new path query language XVerPath over XML document versions, which can be utilized for specifying relevancy-based access control policies. We also introduce the notion of relevancy class, for collectively and compactly specifying relevancy-based policies. Copyright 2005 ACM.

One of the largest barriers to learning programming is the precise and complex syntax required to write programs. This barrier is a key impediment to the integration of programming into the core curriculum of general high school science courses - there is not enough time to learn both syntax and programming in a three-week course module. The newly developed "Iconic programmer" allows executable programs to be written through mouse clicks and menus, includes symbol by symbol translation into Java and Turing, and comes complete with a three-week lesson plan suitable to new programmers. To date, the new tool has been used effectively with full-semester, introductory programming courses at both the university and high school level. Copyright 2005 ACM.

Active learning enables learners to actively engage in learning. Learning not only transfers material to students for learning, but also encourages greater mental engagement and more extensive student-student and student-instructor interaction than does a typical lecture class. Peer instruction (PI) engages students in active learning by achieving continuous instructor-student interaction in a physics lecture. However, the methodologies and the effectiveness of implementing PI for elementary school students have seldom been clarified. This study explores the possibility of adopting PI in an elementary science classroom. The research considerations of the study are as follows: (1) how wireless technology can enhance PI in elementary science classroom; (2) how a teacher can engage students in pre-class reading, and (3) whether elementary school students have sufficient social skills to perform a PI discussion? These questions are examined by observing how the PI pedagogical model worked with a wireless response system in elementary science classroom. Based on the observation, this study also proposes a way of improving the PI learning experience of elementary school students by adding experiments and observations during peer discussion to explain concepts and phenomena in physics.

An emergency response activity usually involves several teams from different organizations working cooperatively for the purpose of saving lives or properties. These teams have to make many decisions under time pressure to accomplish their goals. Most decisions require contextual knowledge coming from the emergency settings, including those which report the activities of other emergency teams. The goal of this paper is to describe a system which aims at storing and disseminating the contextual knowledge required by teams during the course of an emergency.
