In this paper, we describe the advances we have made in extending the quiz component of our VLE (Moodle) to support the drawing and automatic assessment of free-form diagrams. The paper illustrates how diagram-based questions are incorporated into normal Moodle quizzes and the nature of the feedback provided. It describes the types of diagrams that can be supported by the system (graph-based) a...

Without a systematic assessment mechanism, it is hard for teachers to design e-learning courseware and assess students’ on-line learning behaviors. This is a common issue found in most authoring tools available all over the world. Furthermore, some authoring tools are powerful but not standard compliant. To overcome these drawbacks, we propose a courseware design tool with the theory of concept...

This shows PT XYZ as a processing company has problems in achieving product quality. is shown by not target products, even though raw materials are relatively accordance with standards. analysis used cause and effect using fishbone diagram causes problems, well use pareto 5-why support. Failure mode (...

power system overvoltages due to switching, lightning and other disturbances are the main problem for designers of the power transformers. once some frequencies of the incoming surges match with some of the natural frequencies of transformer winding, the resonance phenomenon is expected in transformer winding. the resonant overvoltages may destroy the insulation between turns and cause to insul...

Normal failure or risk analyses procedure contains the following steps: 1) modeling process, 2) assessment process of its hazardous extent. 1) Modeling process is the considering procedure that sets the sequence of happening failures or risks. 2) Assessment process is the evaluation procedure that express its hazardous extent quantitatively or qualitatively (probability, seriousness of injury e...
