With the flourish of online education and distance learning, it's become very important to make the evaluation in e-learning scientifically and objectively. This paper presents an intelligent fuzzy evaluation system based on our innovative evaluation method where management rules made by the experts are used to help, optimize and decide. On this basis, we develop an evaluation method and algorithm...
This work systematically explores the relationship between the resistive switching properties of Pr0.7Ca0.3MnO3 (PCMO) thin film element and its geometry dimensions in deep submicron (DSM) technologies. A series of PCMO-based resistive switch devices (RSDs) with different geometry sizes were fabricated. Our E-test results show that by reducing the PCMO layer thickness from the normal value of about...
This paper deals with a comparative preview of traditional "paper and pencil" tests and computer based tests through both didactical principles and psychological factors. Special accent was put to the adaptive tests. The goal of this paper is to bring this side to foreground, next to the technological aspects, which have been mostly forced. It has been found that the computer tests have...
