Theories of learning in social settings, no matter their philosophical orientation, must address issues of intersubjectivity (IS). This paper starts with the premise that IS is a fundamental and unavoidable aspect of social interaction, and that understanding its nature is necessary for developing reliable theories of socially mediated learning…

The present study contributes to knowledge of the construct validity of the short form of the Teacher Sense of Efficacy Scale (and by extension, given their similar content and psychometric properties, to the long form). The authors' research involves: (1) examining the psychometric properties of the TSES on a large sample of elementary, middle,…

To explore whether teachers' attitudes toward pay for performance are the result of experience or socialization, or whether teachers are already predisposed to prefer pay systems not based on performance, and whether some forms of performance pay might be preferred to others, a study was conducted of the pay system preferences of students…

In his recent bestseller The World Is Flat, Thomas Friedman argues that countries like the United States can no longer compete in the global economy on the basis of making and selling commodities. Their competitive edge increasingly comes from how well they produce products, services, and technologies that are new . . . special . . .…

In this paper, I explore two beliefs about learning and teaching that I argue are prevalent among educators. The first is the belief that subject matter expertise is sufficient for success in teaching. The second belief is that to learn a specific content area, one needs to begin with an understanding of the formal structure and abstract…

This paper examines how middle school students developed understanding of transformational geometry through design activities in Escher's World, a computationally rich design experiment explicitly modeled on an architectural design studio. Escher's World was based on the theory of pedagogical praxis (Shaffer, 2004a), which suggests that preserving…

The recent demand for schools to respond to external accountability measures challenges school leaders to create school instructional systems that use data to guide the practices of teaching and learning. This paper considers how local school leaders build data-driven instructional systems (DDIS) by developing new programs and using existing…

In this paper, we argue that new computational tools problematize the concept of thought within current sociocultural theories of technology and cognition, by challenging the traditional position of privilege that humans occupy in sociocultural analyses. We draw on work by Shaffer, Kaput, and Latour to extend the analytical reach of activity…

Will video games change the way we learn? We argue here for a particular view of games--and of learning--as activities that are most powerful when they are personally meaningful, experiential, social, and epistemological all at the same time. From this perspective, we describe an approach to the design of learning environments that builds on the…

This paper explores the role of co-expressivity of drawing, speech, and gesture as sixth graders strive for intersubjectivity in their attempts to communicate solutions of a spatial reasoning task. Several obstacles to intersubjectivity are documented, particularly conflicts between a literal and geometric interpretation, limits of students'…

Cost analysis has become an important educational decision-making tool in recent years, as educators are being asked to do more with less funding and to provide tangible evidence of the effectiveness of educational programs. Yet few researchers and practitioners are familiar with how to conduct a cost analysis or interpret cost analysis data. This…

As information and communication technologies bring people, places, and events from around the world to desktops, telephones, and televisions, the economic, social, and cultural issues of the globe are becoming increasingly, unavoidably, our own (McLuhan, 1964). Diversity is thus a broader and more complex concept than ever before…

This paper provides an overview of the methods and results of alignment analyses and standard-setting procedures used in investigations conducted during the development of alternate assessments in two states: Wisconsin and Idaho. To meet the assessment and accountability mandates contained in the Individuals With Disabilities Education Act…

This paper presents evidence about the emergence of a research community in mathematics education by contrasting work in the field in the 1960s with current work with regard to six features of such communities. Based on this contrast, the claim that a research community in mathematics education has emerged is only partially supported. (a) Today,…

The primary purpose of the investigation was to determine the extent to which (a) the Wisconsin Alternate Assessment (WAA) adequately measures the skills and concepts that make up the curriculum and instruction of students with significant disabilities; and (b) the WAA adequately measures the concepts and skill areas represented in Wisconsin's…
