Technology CAD Technology CAD Technology CAD (or Technology Computer Aided Design, or TCAD) is a branch of electronic design automation that models semiconductor fabrication and semiconductor device operation. The modeling of the fabrication is termed Process TCAD, while the modeling of the device operation is termed Device TCAD. Included are the modelling of process steps (such as diffusion and ion implantation), and modelling of the behavior of the electrical devices based on fundamental physics, such as the doping profiles of the devices. TCAD may also include the creation of "compact models" (such as the well known SPICE transistor models), which try to
Computer-assisted language learning (e.g. repeating, paraphrasing, slowing down, correcting, or directing the student to background explanations)." Jones C. (1986), on the other hand, rejected the idea of the computer being "some kind of inferior teacher-substitute" and proposed a methodology that focused more on what teachers could do with computer programs rather than what computer programs could do on their own: "in other words, treating the computer as they would any other classroom aid". Warschauer's high expectations in 1996 have still not been fulfilled, and currently there is an increasing tendency for teachers to go down the route proposed by Jones, making use of
