The mathematical background of international students in Technical Master programs is pretty heterogeneous. They often lack of a sound basis in specific topics, which are necessary to follow the Master. Filling this gap is often stressing because it requires these students to make an additional effort reviewing basic references. The goal of this initiative is to produce a tailored learning tool for...
In this article, the authors propose an investigation of the learning process of the concepts and of the mathematical relations in the physical chemistry study of the gas, mapping an interdisciplinary teaching approach. The theoretical background of the research is based on the Theory of Meaningful Learning (ML) and on Gowin's Epistemology trying to relate events, facts and concepts with other elements...
An integrated approach on concept diagnosis is investigated in this study. Polytomous item relational structure (PIRS) is developed so that it is beyond the limitation of dichotomous items. Besides, student problem chart (S-P chart) is used to classify examinee into proper learning style. The integrated methodology of PIRS and S-P chart could display features of concept structures for each learning...
The dynamic geometry system is a typical CAI application that utilizes computer technology to guide geometry learning. In our research of the dynamic geometry on handheld devices, we have successfully implemented a brand new system called "mathematic sketchpad", a part of the Noah graphing calculator. Compared to other similar products like TI or CASIO graphing calculator, the sketchpad...
Web dynamic geometry intelligent drawing is of great significance in the network distance education, particularly in the geometry distance education. On the analysis of the mutual relation between elements of dynamic geometry graphics and methods on how to save graphics in text mode and also strategy of inducting intelligently, this paper realizes a intelligent drawing system of dynamic geometry based...
In order to improve the performances of median filter, a median filter based on judging impulse noise by statistic and adaptive threshold is proposed. This method includes two steps of judging impulse noise pixels and restoring it. First judging impulse noise pixels and signal pixels of edge and smooth area in the corrupted image, then median filter is used for the pixels corrupted by impulse noise...
The students could solve only simple problems passably. The higher the class in which Mathematical knowledge and skills were taught at grammar school the worse the students' mastering of Mathematical concepts and skills. One important reason might be that mathematical knowledge and skills are not examined sufficiently. Final secondary-school examinations in Mathematics are not obligatory until now...
