eric.ed.gov har udgivet: One of the major series of reviews in elementary and secondary education is the Best Evidence Encyclopedia, or the BEE. Up to now, findings for systematic reviews have largely been restricted to the reviews themselves, with few cases in which lessons learned across many reviews using similar methods can be synthesized. The completion of the Best Evidence Encyclopedia reading and math reviews permits a first opportunity to describe both substantive and methodological patterns across a broad set of studies involving all elementary and secondary grades, reviewed using a common set of review procedures. The purpose of the proposed paper is to synthesize both substantive and methodological findings across the five main Best Evidence Encyclopedia reviews of reading and math programs in grades K-12. The paper considers the… Continue Reading →

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 →

eric.ed.gov har udgivet: Karabatsos and Walker (2011) introduced a new Bayesian nonparametric (BNP) regression model. Through analyses of real and simulated data, they showed that the BNP regression model outperforms other parametric and nonparametric regression models of common use, in terms of predictive accuracy of the outcome (dependent) variable. The other, outperformed, regression models include random-effects/hierarchical linear and generalized linear models, when the random effects were assumed to be normally-distributed (Laird & Ware, 1982; Breslow & Clayton 1993), and when the random effects were more generally modeled by a nonparametric, Dirichlet process (DP) mixture prior (Kleinman & Ibrahim, 1998a,1998b). The authors argue that the new Bayesian nonparametric (BNP) regression model provides a novel, richer, and more valid approach to causal inference, which allows the researcher to investigate how treatments causally… Continue Reading →

eric.ed.gov har udgivet: This is a record of the proceedings of the 30th annual conference of the Mathematics Education Research Group of Australasia (MERGA). The theme of the conference is “Mathematics: Essential research, essential practice.” The theme draws attention to the importance of developing and maintaining links between research and practice and ties in with the joint day of presentations with the 21st biennial conference of the Australian Association of Mathematics Teachers (AAMT). This special feature highlights the benefits of collaboration between researchers, practicing classroom teachers, and curriculum developers. Volume 1 contains the following papers: (1) The Beginnings of MERGA (Ken Clements); (2) Teaching and Learning by Example: The Annual Clements/Foyster Lecture (Helen L. Chick); (3) Introducing Students to Data Representation and Statistics (Richard Lehrer); (4) Studies in the Zone… Continue Reading →

eric.ed.gov har udgivet: There are comparatively few studies on one-to-one tutoring in online settings, even though it has been found to be an effective model. This paper explores student-student online coaching from the coach perspective. The empirical case is the project Math Coach, where K-12 students are coached by teacher students using instant messaging. This research is an adaptation of the community of inquiry model to an online coaching setting, which we refer to as a relationship of inquiry. The adapted model was used to gain a better understanding of the practice of online coaching by exploring the extent to which cognitive, social, and teaching presence exists in this case of online coaching. A relationship of inquiry survey was distributed to and answered by all active coaches (N = 41).… Continue Reading →

eric.ed.gov har udgivet: The 2012 Preschool Pilot Study of PBS KIDS Transmedia Mathematics Content (Preschool Pilot) is an important part of the authors’ multiyear “Ready To Learn” (RTL) summative evaluation initiative. Through this initiative funded by the Corporation for Public Broadcasting (CPB) and Public Broadcasting Service (PBS), it was the responsibility of the Education Development Center, Inc. (EDC), and SRI International (SRI) to document and, whenever possible, to measure the impact of transmedia mathematics and literacy resources on learning for children from low-income families across a variety of settings: early childhood classrooms, community settings, and home. In this phase of the evaluation, the authors explored the potential of using technology (interactive whiteboards and laptops) and transmedia resources (digital videos and interactive games)–specifically games developed using the CPB-PBS RTL Mathematics framework,… Continue Reading →

eric.ed.gov har udgivet: The Hampshire Hundreds project was a local authority-led intervention which brought together lead teachers from Hampshire primary schools to provide them with evidence and support for effective teaching strategies to decrease the attainment gap between disadvantaged pupils (aged 9-11) and their peers. The intervention involved a facilitator working with staff from a number of schools, and providing supporting materials comprising the “Hampshire Hundreds Handbook,” to provide good quality teaching and support to disadvantaged pupils. The evaluation was set up as a randomised control trial to test the impact of the Hampshire Hundreds intervention in comparison to a ‘business as usual’ control group, with the local authority leading the training and overseeing the provision of the intervention. As the intervention was run by the local authority it is… Continue Reading →

eric.ed.gov har udgivet: The primary purpose of this study is to determine whether providing structured academic instruction in reading or math to students in grades two to five during their afterschool hours–instead of the less formal academic supports offered in regular after-school programs– improves their academic performance in the subject. This is the second and final report from the Evaluation of Enhanced Academic Instruction in After-School Programs–a two-year demonstration and random assignment evaluation of structured approaches to teaching math and reading in after-school settings. This report includes two parallel impact studies, a math program study (“Mathletics” developed by Harcourt School Publishers) and a reading program study (“Adventure Island” developed by the Success for All Foundation) in which students attending an afterschool program are assigned by lottery to either receive the… Continue Reading →

eric.ed.gov har udgivet: In intervention research, it is critical to determine not just if an intervention is effective, but for whom it is effective and “under what circumstances” those effects occur. Moderators can be the key to answering those questions. A moderator is a variable that affects either the direction or the strength of the relationship between the predictor (curriculum condition, in this case) and the dependent variable (here, child outcomes) (Baron & Kenny, 1986). Identifying those variables that help specify the conditions under which interventions are most effective is central to social science research (Cohen et al. 2003). Moderators of curricular effects may be particularly important to scale-up studies. There may be no more challenging educational and theoretical issue than scaling up educational programs across a large number of… Continue Reading →
