论文摘要
研究学生的学习和对概念物理学的理解是物理教育研究(PER)中的主要研究领域。已经采用了多种定量方法来分析常用的力学概念清单:力概念清单(FCI)和力和运动概念评估(FMCE)。最近,研究人员应用了网络分析技术来探索对FCI识别不正确响应社区的不正确响应的结构,这些响应可以映射到常见的误解。在这项研究中,将用于分析FCI修改模块分析(MMA)的方法应用于大量FMCE预测和测试后响应($ n_ {pre} = 3956 $,$ n_ {post} = 3719 $)。确定的不正确响应的社区与以前的作品中描述的项目组一致。与FCI的工作一样,仅通过保留大量学生选择的节点来简化网络。保留20 \%的学生选择的节点仅产生与四个误解相关的社区。针对男性和女性确定的不正确响应社区大不相同,这些社区从预测试到后测试的变化也大不相同。在产生相似结构的先前工作中,20%的阈值比在FCI中应用于FCI的4%阈值要限制得多。保留5%或10%学生选择的节点产生了大量的复杂社区。在10 \%阈值处确定的社区通常与常见的误解有关,产生了比FCI相比,产生不正确的社区。这可能表明FMCE是表征学生对牛顿力学的误解的卓越工具。
Investigating student learning and understanding of conceptual physics is a primary research area within Physics Education Research (PER). Multiple quantitative methods have been employed to analyze commonly used mechanics conceptual inventories: the Force Concept Inventory (FCI) and the Force and Motion Conceptual Evaluation (FMCE). Recently, researchers have applied network analytic techniques to explore the structure of the incorrect responses to the FCI identifying communities of incorrect responses which could be mapped on to common misconceptions. In this study, the method used to analyze the FCI, Modified Module Analysis (MMA), was applied to a large sample of FMCE pretest and post-test responses ($N_{pre}=3956$, $N_{post}=3719$). The communities of incorrect responses identified were consistent with the item groups described in previous works. As in the work with the FCI, the network was simplified by only retaining nodes selected by a substantial number of students. Retaining nodes selected by 20\% of the students produced communities associated with only four misconceptions. The incorrect response communities identified for men and women were substantially different, as was the change in these communities from pretest to post-test. The 20% threshold was far more restrictive than the 4% threshold applied to the FCI in the prior work which generated similar structures. Retaining nodes selected by 5% or 10% of students generated a large number of complex communities. The communities identified at the 10\% threshold were generally associated with common misconceptions producing a far richer set of incorrect communities than the FCI; this may indicate that the FMCE is a superior instrument for characterizing the breadth of student misconceptions about Newtonian mechanics.
