关于学生对复杂系统理解的一项研究倾向于强调常见误解与相对更复杂的理解之间的不连续性。其他工作的重点是指导，同时承认理解复杂系统的其他方式的存在，但较少强调检查这些中间理解方式中的知识结构。本研究采用微遗传学方法来检验学生对复杂系统行为的解释。使用碎片知识认识论的观点，分析记录了在解释沙丘运动时，推理模式的连续性，跨越较少的原型集中和更多的原型分散（更复杂的因果关系）解释。第一个分析考察了31个访谈，并表明许多访谈反映了一种普遍的推理模式，包括最初的集中解释、最终的分散解释和过渡解释的某种组合。第二项分析考察了单个学生的推理模式，发现相关直觉知识片段（p-prims）和过渡性解释的激活作为推理模式连续体的连续性线索。这些发现表明，学生能够在集中到分散的因果关系中表现出推理模式的连续性，并能够获得适用于沙丘运动宏观和微观层面的复杂系统的生产性直觉知识。结果表明，未来的研究将调查这些过渡性解释以及能够解释这一强健连续体的转移解释机制。
One line of research on student understanding of complex systems has tended to emphasize discontinuities between common misconceptions and relatively more sophisticated understandings. Other work has focused on instruction while acknowledging the existence of other ways of understanding complex systems, but less emphasis has been on examining the knowledge structures within these intermediate ways of understanding. This study takes a microgenetic approach to examining student’s explanations for the behavior of complex systems. Using the Knowledge-in-Pieces epistemological perspective, the analysis documents a continuity of reasoning patterns across less prototypically centralized and more prototypically decentralized (a more sophisticated causality) explanations while explaining the movement of sand dunes. The first analysis examines 31 interviews and shows that many reflected a general reasoning pattern that encompassing some combination of an initial centralized explanation, a final decentralized explanation, and transitional explanations. A second analysis examines a single student’s reasoning pattern and finds that the activation of relevant intuitive knowledge pieces (p-prims) and transitional explanations function as threads of continuity across the continuum of reasoning patterns. These findings suggest that students are able to exhibit a continuity of reasoning patterns across centralized to decentralized causality and are able to access productive intuitive knowledge about complex systems that are applicable to both the macro and micro levels of sand dune movement. Implications suggest that future research investigate these transitional explanations along with the mechanisms of shifting explanations that can account for this robust continuum.
