They use classroom information gathered by the CATS instrument to better understand the potential mediating variables hypothesized to influence student achievement. Their study’s purpose is to gather the kinds of validity evidences that match the proposed interpretations and uses of the CATS instrument (Kane, 2008; Messick, 1995). Therefore, they first explore the content aspect of construct validity by collecting information about the content relevance and representativeness of the observation instrument (Messick, 1995). Second, concerned about the consistency of the observation data collected across a number of independent observers, they measure inter-observer agreement. Finally, they focus on the criterion-predictive aspect of construct validity and investigate… Continue Reading →

eric.ed.gov har udgivet: Given the vital importance of using a scientific approach for curriculum development, the authors employed a design experiment methodology (Brown, 1992; Shavelson et al., 2003) to develop and evaluate, FUSION, a first grade mathematics intervention intended for students with or at-risk for mathematics disabilities. FUSION, funded through IES (Baker, Clarke, & Fien, 2008), targets students’ understanding of whole number concepts and skills and is being designed as a Tier 2 intervention for schools that use a multi-tiered service delivery model, such as Response to Intervention (RtI). In developing this intervention, the authors have drawn extensively from the converging knowledge base of effective math instruction (Gersten et al., 2009; National Math Advisory Panel, [NMAP] 2008) and the critical content areas of first grade mathematics recognized by national bodies… Continue Reading →

eric.ed.gov har udgivet: This paper describes two researchers engagement with two teachers as they taught a middle grades mathematics course, Current Events Math, in a large urban school district. The researchers share bits of data and their ethical entanglements as they entered into the site to find the truth about what works in middle grades mathematics classrooms only to realize that truth cannot be found through research. They then grappled with the question of the purpose of research and their roles as researchers in the school and the academy. [For the complete proceedings, see ED583608.] Link til kilde
