Responds to comments by D. C. Wendt and B. D. Slife (see record 2007-13085-019), P. H. Hunsberger (see record 2007-13085-020), and R. B. Stuart and S. O. Lilienfeld (see record 2007-13085-021) regarding the report by the APA Presidential Task Force on Evidence-Based Practice (see record 2006-05893-001) entitled Evidence-based practice in…

Historically, accounts of object representation and perceived similarity have focused on intrinsic features. Although more recent accounts have explored how objects, scenes, and situations containing common relational structures come to be perceived as similar, less is known about how the perceived similarity of parts or objects embedded within…

By virtue of its connection with scientific literacy, the nature of science has been considered essential subject matter for the science curriculum. With this in mind, seventh-grade students were introduced to three aspects of the nature of science: (1) the distinction between observation and inference, (2) the subjective, and (3) the tentative…

A theoretical advantage of item response theory (IRT) models is that trait estimates based on these models provide more test information than any other type of test score. It is still unclear, however, whether using IRT trait estimates improves external validity results in comparison with the results that can be obtained by using simple raw…

This article aims to address and explain the conceptual ambiguity surrounding distributed leadership. The author argues that there are three different frames for understanding distributed leadership that are being applied simultaneously, but which need to be considered separately. These frames are the theoretical, the empirical and the normative.…

The authors use proven cognitive and learning principles and recent developments in the field of educational psychology to teach the concept of the sampling distribution of the mean, which is arguably one of the most central concepts in inferential statistics. The proposed pedagogical approach relies on cognitive load, contiguity, and experiential…

This article presents the authors' response to McVee, Dunsmore, and Gavelek's "Schema Theory Revisited." In "Schema Theory Revisited," McVee, Dunsmore, and Gavelek (2005) proposed a rearticulation of schema theory intended to encompass the ideas that schemata and other cognitive processes are embodied, that knowledge is situated in the transaction…

Languages are transmitted from person to person and generation to generation via a process of iterated learning: people learn a language from other people who once learned that language themselves. We analyze the consequences of iterated learning for learning algorithms based on the principles of Bayesian inference, assuming that learners compute…

The universality of reading comprehension strategies across languages is a view generally accepted. What has not been clearly established, however, is the degree to which specific comprehension strategies are used by skilled L1 and L2 readers in the early grades. To investigate this issue, similarities and differences in the reading strategies of…

This qualitative, multi-case research study examines how leaders use data to inform decisions related to technology use, including how they use enGauge program evaluation data, identifies leadership practices and related contextual factors present in four K-12 public school districts. This research study examines the questions: What are the…

In well-defined domains such as Physics, Mathematics, and Chemistry, solutions to a posed problem can objectively be classified as correct or incorrect. In ill-defined domains such as medicine, the classification of solutions to a patient problem as correct or incorrect is much more complex. Typical tutoring systems accept only a small set of…

This paper develops the argument that rule and inferential models of communication are interdependent--that explanations provided by one model must invoke properties of the other model if a more complete explanation of communication is to be arrived at. Rule and inferential models are examined separately in the paper as to their functions in…

This study investigated, with a dissociation paradigm, the distinction between remembering the information in a text, and learning from a text and applying the acquired knowledge (e.g., by making inferences). After reading an expository text, subjects (110 undergraduates) performed either a memory (recognition) or an inferencing (verification)…

The categorization of evidence through an "inverse inference" model is a preliminary attempt to organize the manner in which the ordinary language user perceives the use of evidence. While discussions on the nature of evidence have an important place in the realm of the theoretician and methodologist, this model attempts to explain how…

Two parallel studies investigated the influence of principle-based and attribute-based similarity relations on new category learning by preschoolers. One of two possible functions of a single novel artifact (which differed between studies) was modeled for children and practiced by children. Children then judged which test objects received the same…
