Studies of placement tests are typically narrowly concerned with their validation as instruments for the efficient grouping of students. They rarely explore the assumption that placement test content can be related to classroom tasks and so inform instructional decisions. This study focuses on a trial version of the Global Placement Test (GPT), a…

A think-aloud method was used to examine the content of information available to working memory during narrative comprehension in a CHI population. Twenty severe CHI participants (>1 year post-injury) and 20 controls talked aloud after they read each sentence of story narratives. Trabasso and Magliano's (1996a) verbal protocol analysis was then…

This article investigates the transition to memory-based performance that commonly occurs with practice on tasks that initially require use of a multistep algorithm. In an alphabet arithmetic task, item response times exhibited pronounced step-function decreases after moderate practice that were uniquely predicted by T. C. Rickard's (1997)…

Trait conceptions, such as smart, antisocial, and shy, can serve as tools for interpreting and making predictions about the social world. An understanding of children?s trait conceptions can lead to important insights into the way children acquire an understanding of human mental life. The present study was designed to examine positivity biases…

This article is a reflective account of a teacher implementing the comprehension strategy of questioning to encourage genuine conversations with text, instead of the inquisition technique of testing comprehension practiced in many classrooms. Through the structure of a "gradual release of responsibilities," students practice questioning in…

This study examined the effects of contiguity and feature animation on the recall, map reconstruction, inference performance, and en-route behavior of university students studying a computer-delivered reference map with associated text. Participants were randomly assigned to six versions of a computer program created by crossing three contiguity…

In this article, the authors (a) illustrate how displaying disattenuated correlation coefficients alongside their unadjusted counterparts will allow researchers to assess the impact of unreliability on bivariate relationships and (b) demonstrate how a proposed new "what if reliability" analysis can complement null hypothesis significance…

Children learn many new categories and make inferences about these categories. Much work has examined how children make inferences on the basis of category knowledge. However, inferences may also affect what is learned about a category. Four experiments examine whether category-based inferences during category learning influence category knowledge…

The fields of language testing and educational and psychological measurement have not, as yet, developed a set of principles and procedures for linking test scores and score-based inferences to test use and the consequences of test use. Although Messick (1989) discusses test use and consequences, his framework provides virtually no guidance on how…

In 1988, the author taught remedial Senior English reading at a rural high school. None of the students intended to go to college. Instead, they all planned to be homemakers, farmers, or watermen. On the second day of class, he assigned a short story from the cumbersome literature book. The classroom was quiet for a moment, and then one of the…

While technology has become an integral part of introductory statistics courses, the programs typically employed are professional packages designed primarily for data analysis rather than for learning. Findings from several studies suggest that use of such software in the introductory statistics classroom may not be very effective in helping…

The correction for attenuation due to measurement error (CAME) has received many historical criticisms, most of which can be traced to the limited ability to use CAME inferentially. Past attempts to determine confidence intervals for CAME are summarized and their limitations discussed. The author suggests that inference requires confidence sets…

This design study tracks the development of student thinking about natural variation as late elementary grade students learned about distribution in the context of modeling plant growth at the population level. The data-modeling approach assisted children in coordinating their understanding of particular cases with an evolving notion of data as an…

This essay examines contradictory attitudes toward teaching and writing at a small college. Looking at her "private" experience as a teacher and "public" experience as a WPA, the author considers how assumptions about the privatization of teaching inhibit deep understanding of teaching and learning as intellectual work.

Causal inference is an important, controversial topic in the social sciences, where it is difficult to conduct experiments or measure and control for all confounding variables. To address this concern, the present study presents a probability index to assess the robustness of a causal inference to the impact of a confounding variable. The…
