Enhancement of traditional mode of teaching based on the experience of project-based learning
Project based learning (PBL) has become more popular due to its student centered nature of learning compared to traditional modes of learning. However, it is not always feasible to implement it due to several reasons. At the University of New South Wales, the PBL mode was trialled on an introductory Digital Signal Processing course for two consecutive years and the evaluation was previously reported. After that, based on the experience of PBL implementation, some elements of PBL have been incorporated with traditional mode of teaching to enhance the traditional mode and that enhanced traditional mode have been continued. The experience of enhancing the traditional mode with components derived from PBL, particularly the inclusion of conceptual design presentation and laboratory tests, are promising. This paper presents the task description of PBL and experience of how some of the components of PBL can be utilized to enhance the traditional mode of teaching.
Tablet PC and Electronic Whiteboard Use in Signal Processing Education [DSP Education]
This paper discusses the innovative use of the Tablet PC for lectures and the electronic whiteboard for tutorial discussions and laboratories. The paper also presents the new evaluation results on the use of the electronic whiteboard for prerecorded lectures that combine a synchronized lecturer video with dynamic annotation. The results clearly show that signal processing students feel they can review and understand lecture material more effectively with this method. Moreover, their examination performances suggest that higher levels of understanding may be achieved
Accurate measurements of output characteristics and detonations of motorbike high-speed racing engine and their optimization at actual atmospheric conditions and combusted mixture composition
Abstract At a motorbike high speed racing engine there is very important an output engine characteristics which depends significantly on a detonation combustion rate, atmospheric conditions and a combusted mixture composition. The combustion process has got a relevant influence on a wear degree of main engine parts or on their damage eventually. The detonation combustion rate is very important because this kind of burning can be not only destructive but a useful phenomenon, as well. If the process of detonation burning is kept on a certain level, it can help significantly to the next increasing of an engine power output. In this article there is described the measurements of output characteristics of a high-speed racing engine which were performed by means of a data-recording system and the detonation combustion was evaluated using a quantitative method. The actual values of atmospheric conditions and the mixture composition were added to the measured values. Then the obtained values are compared visually with a damage degree of an engine piston caused by the detonation burning. The result is a limit value expressed in a number of detonation units related to a run distance interval of the vehicle driven by the high-speed racing engine. In framework of this run distance interval there is the process of detonation burning profitable. As well as it increases an engine power output and together it is not destructive with regard to engine design parts.
