This paper looks at the need for a better understanding of the impediments to critical thinking in relation to graduate student work. The paper argues that a distinction is needed between two vectors that influence student writing: (1) the word-level-sentence-level vector; and (2) the grammar-inferencing vector. It is suggested that much of the…

In research on learning, one of the fundamental questions concerns issues of language and thought. A number of empirical studies have revealed the interplay between understanding of subject matter and meanings of language expressions to be more dynamic and ambiguous than is commonly acknowledged. The aim of this article is to outline an…

This article describes two studies. The first study was designed to investigate the ways in which the statutory assessments of reading for 11-year-old children in England assess inferential abilities. The second study was designed to investigate the levels of performance achieved in these tests in 2001 and 2002 by 11-year-old children attending…

In this article, the authors focus on hypothesis testing--that peculiarly statistical way of deciding things. Statistical methods for testing hypotheses were developed in the 1920s and 1930s by some of the most famous statisticians, in particular Ronald Fisher, Jerzy Neyman and Egon Pearson, who laid the foundations of almost all modern methods of…

According to one theory about how children learn the meaning of the words for the positive integers, they first learn that "one," "two," and "three" stand for appropriately sized sets. They then conclude by inductive inference that the next numeral in the count sequence denotes the size of sets containing one more object than the size denoted by…

Researchers describe the need for students to have multiple opportunities and social interaction to learn about the differences between observation and inference and their role in developing scientific explanations (Harlen 2001; Simpson 2000). Helping children develop their skills of observation and inference in science while emphasizing the…

The first challenge of accomplishing the goals of any successful instructional system depends on accurately assessing learners and leveraging the information to improve learning (e.g., Conati, 2002; Park & Lee, 2003; Shute, Lajoie, & Gluck, 2000; Snow, 1994). This paper describes an approach for modeling key competencies and developing…

Assessment of complex task performance is crucial to evaluating personnel in critical job functions such as Navy damage control operations aboard ships. Games and simulations can be instrumental in this process, as they can present a broad range of complex scenarios without involving harm to people or property. However, "automatic"…

This document is part of a series of guides designed to help school district leaders address one of the toughest challenges in American education: dropout rates of 30 percent nationwide, 50 percent in many big cities, and 60 percent or more in the lowest-performing schools. It includes tools for data analysts to drill down into the data and use…

Socio-scientific issues have become increasingly important in Science-Technology-Society (STS) education as a means to make science learning more relevant to students' lives. This study used the e-waste issue as a context to investigate two aspects of socio-scientific decision-making: (1) the relationship between the nature of science (NOS)…

This quantitative research examined the differences in struggling readers' comprehension of storybooks according to the medium of presentation. Each student was randomly assigned with one of three conditions: (1) computer presentation of storybooks with animation; (2) computer presentation of storybooks without animation; and (3) traditional print…

Poor comprehenders are generally students who have significant language-learning deficits. A particular problem for students with poor comprehension is that they have difficulty learning new vocabulary because they are inclined to read less, and are unable to apply new meanings to unfamiliar words. This leads to the situation where the gap widens…

The neuropsychological features of the primary progressive aphasia (PPA) syndromes continue to be defined. Here we describe a detailed neuropsychological case study of a patient with a mutation in the progranulin ("GRN") gene who presented with progressive word-finding difficulty. Key neuropsychological features in this case included gravely…

Information provided by examination of the skills that underlie holistic scores can be used not only as supporting evidence for the validity of inferences associated with performance tests but also as a way to improve the scoring rubrics, descriptors, and benchmarks associated with scoring scales. As fluency is considered a critical, perhaps…

Purpose: Previous research has shown that religion plays a role in the lives of many youths. This paper aims to extend previous research and examine attendance at religious services and involvement in religious/church activities as separate items to determine if one aspect was more strongly associated with never having had sexual intercourse among…
