This study illustrates the use of differential item functioning (DIF) and differential step functioning (DSF) analyses to detect differences in item difficulty that are related to experiences of examinees, such as their teachers' instructional practices, that are relevant to the knowledge, skill, or ability the test is intended to measure. This…

Behavioral and economic theories have long maintained that actions are chosen so as to minimize demands for exertion or work, a principle sometimes referred to as the "law of less work". The data supporting this idea pertain almost entirely to demands for physical effort. However, the same minimization principle has often been assumed also to…

In this study, all the advantages of slope parameters, random weights, and latent regression are acknowledged when dealing with component and composite items by adding slope parameters and random weights into the standard item response model with internal restrictions on item difficulty and formulating this new model within a multilevel framework…

We present a quantitative model for predicting the level of difficulty subjects will experience with specific problems. The model explicitly accounts for the number of subproblems a problem can be broken into and the difficultly of each subproblem. Although the model builds on previously published models, it is uniquely suited for blending with…

Recently, Redford (2010) found that monkeys seemed to exert metacognitive control in a category-learning paradigm. Specifically, they selected more trials to view as the difficulty of the category-learning task increased. However, category-learning difficulty was determined by manipulating the family resemblance across the to-be-learned exemplars.…

The purpose of the study was to examine the impact of text difficulty on the oral reading prosody of young children. Fluency in reading is ideally determined by measuring rate, accuracy, and prosodic qualities in the oral reading of children. Spectrographic measurements of four prosodic variables--sentence-final F[subscript 0] change, intonation…

In this study we investigated the role of reading, how writers coordinate editing with other writing processes. In particular, the experiment examines how the cognitive demands of sentence composing and the type of error influence the reading and writing performance. We devised an experimental writing task in which participants corrected an…

Beyond reliability and validity, measures used to model student growth must consist of multiple probes that are equivalent in level of difficulty to establish consistent measurement conditions across time. Although existing evidence supports the reliability of curriculum-based measurement in reading (CBMR), few studies have empirically evaluated…

Research on cognitive load theory (CLT) has not yet provided facet-specific measures of cognitive load. The lack of valid methods to measure intrinsic, extraneous and germane cognitive load makes it difficult to empirically test theoretical explanations of effects caused by manipulations of instructional designs. This situation also imposes…

The Common Core State Standards for English Language Arts (CCSS/ELA) focus on building student capacity to read complex texts. The Standards provide an explicit text complexity staircase that maps text levels to grade levels. Furthermore, the Standards articulate a rationale to accelerate text levels across grades to ensure students are able to…

In pursuit of innovative educational opportunities, district administration piloted competency-based education in their alternative program. This qualitative study used semi-structured interviews with school personnel to document perspectives of the programmatic shift. Analyses found local and national mandates, a catalyst, and a common moral…

This survey study examines an assessment methodology through e-quizzes administered at a military vocational college and subsequent student perceptions in spring 2013 at the "Computer Networks" course. A total of 30 Computer Technologies and 261 Electronic and Communication Technologies students took three e-quizzes. Data were gathered…

This study of advanced readers in Reading First (RF) classrooms was part of a larger evaluation of one state's RF implementation. The study's purposes were to (a) assess the longitudinal growth of advanced primary readers as compared with their non-advanced-reading peers over a 3-year timeframe and (b) determine the degree to which RF classrooms…

We apply a "tutorial design process", which has proven to be successful for a number of physics topics, to design curricular materials or "tutorials" aimed at improving student understanding of important concepts in a university-level introductory materials science and engineering course. The process involves the identification…

What Chinese students learn about American culture and the English language in the classrooms of China does not adequately prepare them for the reality of American culture and communication in English. In this study, the constructs of American culture and models of English language taught in Chinese classrooms are compared with the reality of…
