The use of standards-based classroom assessments to test English learners' language proficiency is increasingly prevalent in the United States and many other countries. In a large urban school district in California, for example, a classroom assessment is used to make high-stakes decisions about English learners' progress from one level to the…

This study provided 5 weeks of direct strategy instruction about narrative elements and relations in 4 first-grade classrooms (n = 83), all with materials that made minimal decoding demands on children's reading. Two comparison classrooms (n = 40) received comparable instruction on language development and poetry. A battery of assessments given at…

This paper defines Bayesian network models and examines their applications to IRT-based cognitive diagnostic modeling. These models are especially suited to building inference engines designed to be synchronous with the finer grained student models that arise in skills diagnostic assessment. Aspects of the theory and use of Bayesian network models…

The accuracy of achievement test score inferences largely depends on the sensitivity of scores to instruction focused on tested objectives. Sensitivity requirements are particularly challenging for standards-based assessments because a variety of plausible instructional differences across classrooms must be detected. For this study, we developed a…

Purpose: This study examined the association between cognitive functioning and completion of a durable power of attorney for health care. Design and Methods: Participants were from the Second Longitudinal Study on Aging (LSOA II), a nationally representative sample of community-dwelling persons who were at least 70 years of age at the time of…

In a qualitative, multiple case study, we explored the challenges and successes teachers encounter while participating in a professional development program aimed at improving their reading comprehension instruction so as to increase students' self-regulated use of comprehension strategies. We documented five fifth grade teachers' experiences as…

Recent developments in cognitive psychology suggest models for knowledge and learning that often fall outside the realm of standard test theory. This paper concerns probability-based inference in terms of such models. The essential idea is to define a space of "student models"--simplified characterizations of students' knowledge, skill,…

Conjunctions (e.g., "if, and, so") appear in varied contexts and are associated with a wide range of interpretations. The theoretical options concerning the lexical specifications of these items are: (1) multiplicity of senses; and (2) restricted senses augmented by conversational implicatures. It is proposed here that the latter…

The core of schema theory is the concept that text is understood according to the reader's world knowledge and that this knowledge is altered whenever the reader encounters new information in print. Inferencing, that is the hypothesizing or predicting that the activation of schema sets in motion, is critical in this process. Recall is important…

A study in which the ability of Peruvian teachers of English as a Second Language to simplify their own use of English appropriately for classroom use was examined, is discussed. It is noted that the study provides new data and has implications for future research on classroom language. It supports prior work on teacher talk and implies that…

Bayesian methods for estimating dose response curves in quantal bioassay are studied. A linearized multi-stage model is assumed for the shape of the curves. A Gibbs sampling approach with data augmentation is employed to compute the Bayes estimates. In addition, estimation of the "relative additional risk" and the "risk specific…

This article outlines strategies for the inferring of English scientific terms by Spanish speakers. The article considers factors affecting the process of inference, the use of context morphology, and word origin in inferring word meaning. (SR)

A study investigated whether classroom reading instruction that focuses students' attention on story characters' motives and feelings improves their narrative comprehension. The subjects for this study were 48 third-grade students from 3 different classrooms in the same school. Two different treatments were used: the External Events (control)…

This paper describes a procedure for smoothing the proportions of a double-entry expectancy table which might be used in higher education admissions advising or other functions. The product of the smoothing procedure is a nomograph, a medium for displaying expectancies which provides pairs of individual values for two predictor variables rather…

Focusing on the process of reading comprehension, this book contains chapters on some central topics relevant to understanding the processes associated with comprehending text. The articles and their authors are as follows: (1) "Comprehension Processes: Introduction" (K. Rayner); (2) "The Role of Meaning in Word Recognition"…
