Conclusions<br />
The objects <strong>of</strong> this study are the courses <strong>of</strong>fered in micr<strong>of</strong>abrication technology that have their concentrations on<br />
experimentations as well as on practical training. This study has developed a web-<strong>based</strong> system that is interactive <strong>to</strong><br />
support self-directed learning <strong>of</strong> the MEMS technologies, which incorporated the developed web-<strong>based</strong> system with<br />
the courses in question. The blended methodology allowed for a balanced combination <strong>of</strong> the teacher-centered<br />
teaching approach and the student-centered one. As it has been found, most students preferred the blended style <strong>of</strong><br />
learning, and that the learning performance delivered by the Experimental group showed significantly higher<br />
effectiveness <strong>of</strong> the instructions provided, in terms <strong>of</strong> teaching <strong>of</strong> micr<strong>of</strong>abrication. The students generally provided<br />
positive feedback regarding the self-directed navigation <strong>of</strong> the web-<strong>based</strong> learning system while participating in<br />
micr<strong>of</strong>abrication courses. Most students also considered the blended learning system <strong>to</strong> have been helpful when it<br />
comes <strong>to</strong> learning the technical operations that are relevant <strong>to</strong> micr<strong>of</strong>abrication; it has enabled the students <strong>to</strong> learn<br />
such operations on the Internet on a persistent basis that familiarized them with micr<strong>of</strong>abrication technologies.<br />
The web-<strong>based</strong> learning system that has been developed out <strong>of</strong> this study not only assisted students <strong>to</strong> operate the<br />
MEMS and the related manufacturing techniques, it also allowed for process planning <strong>to</strong> be achieved in cyberspace<br />
and was well-received by the students. In the field <strong>of</strong> technological education, although there had been researchers<br />
