Among his many accomplishments in educational psychology, Merlin C. Wittrock is perhaps best remembered for his enduring contributions to the science of learning. His vision of how learning works is best explicated in articles published in "Educational Psychologist" (Wittrock, 1974, 1978, 1989, 1991, 1992), beginning with his classic 1974 article,…

This appreciation of Wittrock's contributions to educational psychology suggests that his 1974 article describing generative learning theory was remarkably prescient. In that article Wittrock set the stage for the subsequent paradigm shift from cognitive to constructivist approaches to instruction. Furthermore, his suggestion that schools were the…

In this article, I examine developments in research on achievement motivation and comment on how those developments are reflected in Wittrock's generative model of learning. Specifically, I focus on the roles of prior knowledge, the generation of knowledge, and beliefs about ability. Examples from Wittrock's theory and from current motivational…

Merlin C. Wittrock was a friend and colleague who influenced me and many other contemporary mathematics educators on how students learn. In this article I summarize my interactions with Merl beginning in 1965, and how over the following half-century he influenced my thinking on student learning for understanding and, in turn, on how to design…

Merl Wittrock, a cognitive psychologist who had proposed a generative model of learning, was an essential member of the group that over a period of 5 years revised the "Taxonomy of Educational Objectives," originally published in 1956. This article describes the development of that 2001 revision (Anderson and Krathwohl, Editors) and Merl's…

We describe some of Merl's more subtle contributions that extended beyond his own prodigious scholarly record, his high-quality teaching, and his mentoring of students. The context of our remarks on Programmatic R&D focuses on his contribution to the University of California, Los Angeles, Department of Education. Merl was the first director of the…

In this article, Lyn Corno and Edys Quellmalz reflect on their experiences with Merl Wittrock as a supportive mentor early in their careers.

This article explores the use of standardized tests to hold schools accountable. The history of testing for accountability is reviewed, and it is shown that currently between-school differences account for less than 10% of the variance in student scores, in part because the progress of individuals is small compared to the spread of achievement…

In this article, we examine the relations of value-added models of measuring academic achievement to student motivation. Using an achievement goal orientation theory perspective, we argue that value-added models, which focus on the progress of individual students over time, are more closely aligned with research on student motivation than are more…

Asked to review the four articles that appear in this special issue of "Educational Psychologist," these authors discuss the articles in alphabetical order, describe their major arguments, analyze strengths and weaknesses from their perspective, and provide some considerations. The analysis section about each article brings their perspective to…

The goal of this special issue of "Educational Psychologist" is to consider the challenges of schooling in the age of accountability. Four experts were invited to review and evaluate the relationship between school accountability and school improvement, professional development, assessment, and student motivation. Each article provides suggestions…

Many wonder whether the No Child Left Behind Act of 2001 (NCLB) will realize its goal of improving achievement among low-performing students in high-poverty schools. An examination of assumptions that underlie the accountability and school improvement aspects of this federal policy suggests that it will not. In spite of the coherence of the…

For professional development to be effective as an accountability policy mechanism, it must address challenges posed by accountability while also building teachers' capacity to change. This article details the role of professional development in the accountability system and provides a review of literature on effective professional development,…

This article discusses the occurrence and measurement of self-regulated learning (SRL) both in human tutoring and in computer tutors with agents that hold conversations with students in natural language and help them learn at deeper levels. One challenge in building these computer tutors is to accommodate, encourage, and scaffold SRL because these…

In this response, we acknowledge the central concerns of the commentators to our article on learning's topography. We respond to those concerns on the basis of the multiplicity of views about learning that reside within the learning terrain we outlined in Alexander, Schallert, and Reynolds (2009/this issue).
