Valid and reliable measurements of teaching quality facilitate school-level decision-making and policies pertaining to teachers. Using nearly 1,000 word-to-word transcriptions of fourth- and fifth-grade English language arts classes, we apply novel text-as-data methods to develop automated measures of teaching to complement classroom observations…

The motivation for this paper is the authors' recent work on several randomized control trials in which they found the primary result, which averaged across subgroups or sites, to be moderated by demographic or site characteristics. They are led to examine a distinction that the Institute of Education Sciences (IES) makes between "confirmatory"…

This issue brief focuses on one particular report, released in September 2009, that has been widely cited by charter school advocates because it appears to show remarkable results. In the report, "How New York City's Charter Schools Affect Achievement," Stanford University professor Caroline Hoxby and her colleagues Sonali Murarka and…

This paper provides practical guidance for researchers who are designing and analyzing studies that randomize schools--which comprise three levels of clustering (students in classrooms in schools)--to measure intervention effects on student academic outcomes when information on the middle level (classrooms) is missing. This situation arises…

This study compares three variations in how researchers construct middle childhood social networks: (1) with "friendships" or "affiliations" as a relational tie; (2) with children providing "self reports" of relationships, or in addition, "multi-informant reports" of relationships in which they are not involved; and (3) whether network computation…

This article describes a case study of an international collaboration between two classes of fifth grade students through an online discussion platform with one group more experienced in online knowledge building activities than the other. Before the collaboration, the novice class tended to produce isolated notes filled with information and…

Within the context of the Project on Learning (a 3-year research project under the direction of Professor Graham Nuthall), each of the authors of this paper participated in a series of classroom-based studies focussing on the experience of Years 5 and 6 students. The use of the extensive methodology, comprising audio- and video-recorded…

Some common complications that arise in collaborative research between school and university researchers, as well as some conditions for successful collaboration are described in this report. Difficulties possibly attributable to developmental levels of the researchers are discussed utilizing Kegan's (1982) theory of constructive developmentalism.…
