Introduction: Due to development of educational systems and importance of education in the nursing profession, the necessity of using appropriate instructional methods for new theoretical and practical skills in students is clear. The purpose of this study is comparing the effects of three methods lecture, problem solving, and computer-assisted self learning on the drug calculation skill on thi...
A fixture is a mechanism used in manufacturing to hold a workpiece, position it correctly with respect to a machine tool, and support it during machining. Typically, fixture design involves the identification of clamp, locator, and support points, and the selection of corresponding fixture elements for their respective functions. The automation of fixture design activities in manufacturing is a...
PURPOSE The purpose of this study was to compare the surface dose of 7-field IMRT (7 F-IMRT), tangential beam IMRT (TB-IMRT), and tangential beam 3D-CRT (3D-CRT) of breast cancer patients receiving adjuvant radiotherapy by means of in vivo GafChromic film dosimetry. MATERIAL AND METHODS Breast cancer patients receiving adjuvant radiotherapy of the whole breast or the chest wall were eligible ...
the present study compares the performance of two tefl reading classes: one taking place in a regular classroom and the other held in a computer lab, with the learners practicing reading online. the results of an independent samples t-test showed that the difference between the learners’ scores on their reading comprehension post-tests and pretests did not differ statistically significantly fro...
the present study was conducted to evaluate data driven learning (ddl) combined with computer assisted language learning (call) as an approach to improving vocabulary knowledge of iranian postgraduates majoring in teaching english, english literature and translation. the purpose was to help language learners get familiar with ddl as a student-centered method taking advantage of a computer progr...
This paper describes a process to consolidate observations and findings from usability evaluation phases into a comprehensible list of usability deficiencies as a basis for quality assurance methods. A so called “evidence test” process is transferred from the world of software usability engineering into the context of computer aided learning (CAL) and computer supported cooperative learning (CS...
This sketchy note tries to answer the question put forward "What is your view of the future of Computer Algebra". Part of the answer is to explore better the links with Computer Science. We stress the fact that a question raised by John Mc Carthy in 1963 on the interaction between Algebra and Logic can set partly an agenda for future research. To foresee the future of a scientiic eld is a hazar...
The interaction of radiation with cells and tissues has a random nature. Therefore, understanding the random nature of cell killing that is determined by Poisson distribution statistics is an essential point in education of radiation biology. RadBioStat is a newly developed educational MATLAB-based software designed for computer-assisted learning of the target theory in radiation biology. Altho...
