Eric.ed.gov – Locating Differential Effectiveness of a STEM Initiative through Exploration of Moderators

eric.ed.gov har udgivet: In randomized control trials, such as the one the authors conducted in Alabama, moderators are potentially an important source of variation in treatment effects. Whether moderators used in the RCT’s analysis are pre-existing characteristics of students, their teachers, or the school or other organizational context, they can point toward differences in the way the program (treatment) is implemented, the way teachers interact with different kinds of students when implementing the program, or how effects are operating at levels in the organization above the level where the differences were measured. The authors appreciate Cronbach’s (1975) metaphor of the “hall of mirrors” to point to the endless possibilities for higher-order interactions complicating the explanation of what was found. But the goal of this paper is to illustrate a disciplined… Continue Reading

tandfonline.com – Stories from the field: locating and cultivating computational thinking in spaces of learning

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT There is considerable debate and ambiguity around what constitutes “computational thinking” (CT). In contrast to Computer Science which is generally treated as a distinct field of study, CT as a construct highlights the integral relationship between computing and other fields. Many recent efforts seek to map computational thinking by making high-level connections to other school disciplines. We argue that while these efforts may help identify specific curricular areas in which computing is likely to take place, they do not sufficiently capture the specificity and dynamism that is characteristic of meaningful computational integration. Worse, they exclude generative examples of computing integration that exist outside of the traditional STEM context or researcher-led efforts. In this special issue, we offer a… Continue Reading
