Electrical Discharge Machine (EDM) is one of the non-traditional machining processes. EDM process is based on thermoelectric energy between the work and an electrode. A pulse discharge occurs in a small gap between the work piece and the electrode and removes the unwanted material from the parent metal through melting and vaporization. The electrode and the work piece must have an electrical co...

Research work is being undertaken at the Center for Innovation and Product Design at the Monterrey Institute of Technology (Mexico), looking for the integration of different design tools and methodologies to increase product design effectiveness and productivity. This paper describes the integration of TRIZ and “Classical” Design Methodologies as Morphological Matrix during the design process a...

Content Analysis of Seventh Grade’s Science Textbook in terms of Problem Solving Stages M. Sami’ee Zafarghandi, Ph.D. F. Khojasteh The national curriculum in science is not geared solely toward the development of scientific skills and transfer of knowledge products. Accordingly the learning of scientific methods is among the main objectives of science education. To...

Predicting Student Performance in Verbal Math Problems Based on Cognitive, Metacognitive, and Affective Factors F. Karimi, Ph.D. A.R. Moraadi, Ph.D. P. Kadivar, Ph.D. R. Kormi Noori, Ph.D. To determine the predictive role of metacognitive, cognitive, and affective factors in solving verbal math problems, a cluster sample of 450 junior high school  students was given ...

central to vygotsky-inspired sociocultural theory (sct) is the notion of zpd seen by sla researchers as a useful framework within which l2 teaching and learning can take place. van lier (2004) argues that the zpd could be activated in diverse proximal contexts (pcs) and is not limited to the expert-novice scenario. . this study probed whether iranian efl learners' collaborative task performance...

TRIZ can be considered as specific problem solving approaches. It uses among others concepts like problem and systems. This paper is a trial to describe with general tools of system and problem modelling how model of problem and model of system evolves through ARIZ process or at least through some of it steps. The purpose of this article is to show that problem solving, and particularly, proble...
