摘要

摘要:遵循以证据为中心的设计的扩展视角,本研究提供了一个从日志数据中构建过程指标的基于理论的方法论范例。我们研究了作为目标结构的网络搜索中的决策过程,假设个人遵循启发式搜索(关注搜索结果与网站作为主要信息源)和停止规则(遵循满意与抽样策略)。根据这些假设,我们描述了我们的推理,以确定所需的经验证据,并选择一项评估来获得这些证据,从而得出代表通过搜索和停止规则组合区分的群体的过程指标。为了评估我们的方法,我们重新分析了150名大学生的处理行为,他们在四项任务中被要求从五个搜索结果列表中选择一个特定的网站。我们确定了每个项目的过程指标,并进行了多个聚类分析,以调查群体恢复情况。对于每个项目,我们发现了三个集群,其中两个与我们的假设相匹配。此外,我们探讨了学生集群成员在项目之间的一致性,并调查了他们与学生评估在线信息技能的关系。基于结果,我们讨论了构造广度和过程细化之间的权衡,以获得有意义的过程指标。

Theory Matters
Abstract: Following an extended perspective of evidence-centered design, this study provides a methodological exemplar of the theory-based construction of process indicators from log data. We investigated decision-making processes in web search as the target construct, assuming that individuals follow a heuristic search (focusing on search results vs. websites as a primary information source) and stopping rule (following a satisficing vs. sampling strategy). Drawing on these assumptions, we describe our reasoning for identifying the empirical evidence needed and selecting an assessment to obtain this evidence to derive process indicators that represent groups differentiated by search and stopping rule combinations. To evaluate our approach, we reanalyzed the processing behavior of 150 university students who were requested in four tasks to select a specific website from a list of five search results. We determined the process indicators per item and conducted multiple cluster analyses to investigate group recovery. For each item, we found three clusters, two of which matched our assumptions. Additionally, we explored the consistency of students’ cluster membership across items and investigated their relationship with students’ skills in evaluating online information. Based on the results, we discuss the tradeoff between construct breadth and process elaboration for deriving meaningful process indicators.

期刊介绍: The main purpose of the EJPA is to present important articles which provide seminal information on both theoretical and applied developments in this field. Articles reporting the construction of new measures or an advancement of an existing measure are given priority. The journal is directed to practitioners as well as to academicians: The conviction of its editors is that the discipline of psychological assessment should, necessarily and firmly, be attached to the roots of psychological science, while going deeply into all the consequences of its applied, practice-oriented development.
