objectives: the purpose of this study was to develop and test a new tool for radiographic densitometry by combining periapical films and aluminum step wedge. materials and methods: we reviewed 50 kodak e-speed intraoral films. an aluminum step wedge consisting of 16 steps was constructed. each step was 1mmx3mx10mm. the step wedge was exposed to varying exposure times, ranging from 0.05 second t...

introduction: medical undergraduates usually understand and memorize anatomical course material with difficulty. also, the current text books and atlases of anatomy and histology do not fulfill all the learning needs of the undergraduates. therefore, it is necessary to consider the role of internet websites and computer programs (i.e. the role of electronic learning) in teaching. the present re...

Computer aided assessment is a common approach used by educational institutions. The benefits range into the design of teaching, learning, and instructional materials. While some such systems implement fully automated marking for multiple choice questions and fill-in-the-blanks, they are insufficient when human critiquing is required. Current systems developed in isolation have little regard to...

Review by Pia Sundqvist, Karlstads Universitet Technology-mediated TBLT: Researching Technology and Tasks, edited by Marta González-Lloret and Lourdes Ortega, presents a new framework in which tasks and technology are integrated in the language curriculum. Although Task-Based Language Teaching (TBLT) and Computer-Assisted Language Learning (CALL) have been around for some time, the integration ...

The Machine Translation course at Dublin City University is taught to undergraduate students in Applied Computational Linguistics, while Computer-Assisted Translation is taught on two translator-training programmes, one undergraduate and one postgraduate. Given the differing backgrounds of these sets of students, the course material, methods of teaching and assessment all differ. We report here...

Cooperative leaning techniques have their own unique advantages for the teacher and the students. This paper is to discuss the English teaching model of cooperative learning in the network environment in higher vocational education based on theory of cooperative learning and theory of computerassisted cooperative learning. First, it introduces the characteristics of the computer-assisted cooper...

As technology increasingly takes center stage of our lives, there are compelling reasons for incorporating technologies into the classroom. The prevailing of CALL (Computer Assisted Language Learning) has greatly changed the traditional teaching mode and added new contents into the existing teaching materials. As a significant skill for EFL (English as a Foreign Language) learners, there are ab...

A memory-training program previously used effectively upon persons with head-injury (HI) was conducted upon eight subjects with multiple sclerosis (MS). The program involved computer-assisted teaching of imagery-based mnemonic strategies for recall of lengthy lists of words, and for associating names with faces. Results were similar to those found in individuals with HI, but the MS subjects lea...

ÐAt the Open University (OU), the perception of computer assisted learning (CAL) is shifting from its current position as an optional extra in a battery of course components to that of a key teaching medium. This paper presents the authors' experiences of the evaluation of a range of current OU produced computer assisted learning materials, mainly but not exclusively in science and technology r...
