This article is a version of the American Psychological Association Division 15 Presidential Address presented at the 2001 annual meeting of the American Psychological Association. In this address, Alexander outlines four trends that influence postindustrial society in general and educational psychology in particular. Those trends are (a)…

This article explores the complex, hierarchical relation among school characteristics, individual differences in academic achievement, extracurricular activities, and socioeconomic background on performance on the verbal and mathematics Scholastic Aptitude Test (SAT). Using multilevel structural equation models (SEMs) with latent means, we…

This article describes two projects based on Robert J. Sternberg's theory of successful intelligence and designed to provide theory-based testing for university admissions. The first, Rainbow Project, provided a supplementary test of analytical, practical, and creative skills to augment the SAT in predicting college performance. The Rainbow…

Empirical research is all about trying to model and predict the world. In this article, I discuss how design-based research methods can help do this effectively. In particular, design-based research methods can help with the problem of methodological alignment: ensuring that the research methods we use actually test what we think they are testing.…

Designed learning environments embody conjectures about learning and instruction, and the empirical study of learning environments allows such conjectures to be refined over time. The construct of embodied conjecture is introduced as a way to demonstrate the theoretical nature of learning environment design and to frame methodological issues in…

In this article, I argue that when design and intervention are central to the research process, context as a construct is problematized. How we define context can facilitate or impede our ability to construct rich and veridical accounts of learning. A design stance may predispose us to less profitable notions of context. I present the advantages…

Recent interest in design-based research as a research and development methodology in education has begun to clarify the goals and commitments involved in this practice. So far, we have limited views into how the work of design and the work of research impact each other in the course of design-based investigations. In this article, I use the…

Over the past decade, design experimentation has become an increasingly accepted mode of research appropriate for the theoretical and empirical study of learning amidst complex educational interventions as they are enacted in everyday settings. There is still a significant lack of clarity surrounding methodological and epistemological features of…

The call for design research, design-based research, or design experiments arose from the recognition of the complexity of classroom interventions and dissatisfaction with existing methodologies for exploring the outcomes from such interventions. The goal of the proposed design research was to describe how interventions worked and was less about…

Critically examines the portions of Arthur Jensen's books that concern Barbara Burks' 1928 study of adoptive families. Findings are that Burks' sample was highly selective, that her environmental measures were limited, and that Jensen has misrepresented the content and implications of her study. It is also shown that Jensen's estimates of…

Investigated the rationale for teaching psychology from the jr. high school level through college and compared the three principal contemporary approaches favored by psychologists. The author concluded that, of the three, only cognitive psychology provides a frame of reference in which knowledge can be seen as valuable in its own right. Available…

Discusses cognitive mechanisms facilitating effective problem solving in physics (mechanics). Considers content, organization, and description of the knowledge base facilitating scientific problem solving. Also considers procedures used to describe and analyze a problem initially, to search for its solution, and to assess the solution. Educational…

Physics learning studies demonstrate that students' pre-instructional world knowledge is often logically antagonistic to the principles of Newtonian mechanics taught in introductory physics courses. Under these conditions psychological theory predicts that learning will be inhibited, a prediction consistent with both the experiences of physics…
