Abstract

process. Those steps would help them bring the design task from its abstractive state closer to its concrete end objective. Each design phase had become the transitioning phase for the next phase and it led this team to focus themselves from their initial abstract and conceptual state of understanding to a more concrete object. The abstract and qualitative understanding of the project had eventually become manifested into real physical components before they were finally able to produce the end product, a working hydraulic bicycle.

In order to gain a better understanding of these students’ self management of cognition during the design processes, each of the design phases will be explored in detail. To simplify the discussion, the prototype construction phase and the testing and modification phase are combined.

Research and literature review. The research and literature review were conducted in order to gain a firm grasp on the main concepts of hydraulics, bicycles, and previous hydraulic bicycle designs. The team believed that because they had a good understanding of these three concepts, they had a clear idea on the complexity of the design tasks. Moreover, they also believed that by having some understanding of these three main concepts, it had given them some level of self- confidence in completing the project. Understanding these technical issues did not only provide this team with some insights about the technical aspects of building a hydraulic bike, but it also offered a common metacognitive tool [11] so these students could achieve self-appraisal and self-management of their own thinking.

During this phase, these students acquired some declarative knowledge about the project by first identifying the components (e.g., hydraulic pumps and motors), design parameters, and relationship among those components that might affect the performance of their hydraulic bike. As Linda put it, “During this phase, we focused on the what thing rather than the how thing.” Special attention was given to learn about these components as each component has its own working characteristics that have direct impact on the performance of the bike. Lessons learned from studying the historical aspect of the hydraulic bike were also integrated in this team’s future design.
