Figure 1: This is the example, illustrating the proof above. The black matching is M and the orange matching is M ′. The lists beside m,w shows their preference list. We know that m prefers his match in the black matching, w, to his match in the orange matching, w′. For purposes of contradiction, we assumed that w prefers m to m′. As you can see, this implies that the pair (m,w) is an instabili...

Classroom clickers, also called group response systems, represent a form of technology-enhanced learning. An instructor can pose a question to the class during a lecture, and students can use their clicker devices to submit their answers. The system immediately aggregates the submissions and presents feedback to the instructor (and possibly the

Concerns about a lack of face-to-face contact with students, a focus on grading rather than teaching, and limited expertise with technology or needed pedagogical strategies, may contribute to instructor reluctance to teach online. The interaction between the instructor and learner and among learners affects the quality and success of online learning, and the learner’s ability to master the outc...

This case study explores the role of the online instructor and how they influence student satisfaction. While there has been a substantial body of literature on what impacts on student satisfaction when students study online, there is far less literature focussing on how the instructor mediates this satisfaction, in particular satisfaction related to quality of feedback and teaching. This case ...

A geothermal power plant multiple simulator for operators training is presented. The simulator is designed to be installed in a wireless local area network and has a capacity to train one to six operators simultaneously, each one with an independent simulation session. The sessions must be supervised only by one instructor. The main parts of this multiple simulator are: instructor and operator’...

Adv Physiol Educ 28: 107–111, 2004; 10.1152/advan.00049.2003.— We previously examined how three approaches to directing students in a laboratory setting impacted their ability to repair a faulty mental model in respiratory physiology (Modell, HI, Michael JA, Adamson T, Gold...

The role of instructors as users/authors of ITS authoring tools is very important for the effectiveness of the produced ITSs. In order for authoring tools to benefit the most from the involvement of instructors, they should provide individualised feedback to them throughout the ITS’s life cycle. In most cases the addition of an instructor modelling component to the architecture of an authoring ...
