This paper analyzes the existing problems in the teaching of memory management of operating systems, presents a reformed teaching scheme, and introduces its adoption and effects in teaching practices. This teaching scheme consists of a head model, a main body model and a summary model, among which the four-space summary model is the most distinguishable characteristic. The scheme has been imple...

The present paper introduces a new model for teaching randomized learners. Our new model, though based on the classical teaching dimension model, allows to study the influence of various parameters such as the learner’s memory size, its ability to provide or to not provide feedback, and the influence of the order in which examples are presented. Furthermore, within the new model it is possible ...

A Standard Model for Measuring Professional Competencies of Teachers in the Islamic Republic of Iran   S. Askari Matin* G.R. Kiyaani, Ph.D. **   Professional development and learning for teachers is an effective approach to guaranteeing the quality of output in educational systems. Such an undertaking could lead to higher levels of competency among teachers as an important interm...

A significant research base has increasingly substantiated that teachers are among the most significant players affecting student achievement in second language classrooms. As a result, teacher-related variables have enjoyed much research attention over the recent decades in both mainstream education and English Language Teaching (ELT). Likewise, the present study was set to test a stru...

This paper describes the um scrutable user modelling approach and explores the extension of the approach and philosophy into the teaching strategy. Essentially, um represents the evidence about the student in a form that can be scrutinised either directly, or via a graphical interface. This form of the student model is reusable by different teaching systems and other applications. It is only at...

We consider the concept classes of DNF formulas and unions of discretized, axis-parallel d-dimensional boxes in discretized d-dimensional space with respect to several different learning models. In the model of learning with queries we present an algorithm to learn unions of boxes. We introduce a model of teaching that prevents illicit communication between the teacher and the leaner but that c...
