  • Future MEMS systems will be composed of larger varieties of devices with very different functionality such as electronics, mechanics, optics and bio-chemistry. Integration technology of heterogeneous devices must be developed. This article first deals with the current development trend of new fabrication technologies; those include self-assembling of parts over a large area, wafer-scale encapsulation by wafer-bonding, nano imprinting, and roll-to-roll printing. In the latter half of the article, the concept towards the heterogeneous integration of devices and functionality into micro/nano systems is described. The key idea is to combine the conventional top-down technologies and the novel bottom-up technologies for building nano systems. A simple example is the carbon nano tube interconnection that is grown in the via-hole of a VLSI chip. In the laboratory level, the position-specific self-assembly of nano parts on a DNA template was demonstrated through hybridization of probe DNA segments attached to the parts. Also, bio molecular motors were incorporated in a micro fluidic system and utilized as a nano actuator for transporting objects in the channel.

  • In this study, the effects of feedback types in self-assessment on the students' science concept understanding and science-related attitudes were investigated. Student's perceptions towards the self-assessment and the feedback provided were also examined. Ten classes from a middle school were chosen. Five of those classes were assigned to the comparative group that any type of feedback was not provided and the other five classes were assigned to the experimental group which feedback was provided. The experimental group was further divided into three groups for implement of three types of feedback. Experimental group A was given feedback in the form of written comments and experimental group B was provided feedback through correct-wrong response to the students answer. Experimental group C was provided oral feedback to the whole class. The tests of science-related attitudes were administered before and after the instruction period. The science concepts understanding test was done only after the instruction. There were significant differences between the experimental group and comparative group in understanding of scientific concepts. The enhancement of science-related attitudes was also significantly higher for the experimental group. There were significant differences between the experimental groups in science-related attitudes. However, there were no significant differences in understanding of scientific concepts in relation to the types of feedback in experiment groups. Interviews with the students of the experimental groups showed that students had positive attitudes towards self-assessment and the types of feedback. And they regarded self-assessment and feedback as helping them understand the science concepts. In conclusion, it was acknowledged that providing feedback in self-assessment showed considerably positive influences on the improvement of the understanding of scientific concepts and science-related attitudes.

  • In this study, we investigated the influences of students' motivational characteristics on the processes of learning density concept using a discrepant event. The participants were 642 seventh graders from two middle schools. Tests of failure tolerance, self-efficacy and mastery/performance goal orientation were administered as pretests. A preconception test was also administered. The intervention was the students' individual study of the density concept with a worksheet that was designed to incorporate the major steps of conceptual change learning. The tests of attention, effort and conceptual understanding were administered as post-tests. The responses of 203 students who had been found to possess the target misconception were analyzed. The results of a path analysis revealed that students' motivational characteristics variables did not influence cognitive conflict. Failure tolerance and mastery goal orientation, however, influenced conceptual understanding via situational interest, attention and effort. Self-efficacy influenced conceptual understanding via effort. Performance goal orientation negatively influenced conceptual understanding via attention and effort. Cognitive conflict influenced conceptual understanding directly as well as indirectly via situational interest.
