Our purpose in this paper is to apply selected notions from cognitive grammar, natural phonology, and item response theory in order to give better insight on ESL subjects’ processing of the D and Z morphemes in English.

Mixed Connective Tissue Disease (MCTD) and Systemic Lupus Erythematosus (SLE) are autoimmune rheumatic diseases that are difficult for physicians to diagnose and to distinguish for a variety of reasons. The correct classification of these two diseases is a crucial issue for clinicians who treat autoimmune rheumatic diseases. In prior research, medical risk factors represented by instrument or laboratory measures and physician judgments (12 key features for MCTD and 12 key features for SLE) were parameterized with a one parameter logistic function in a Rasch model. Those results identified separate diagnostic dimensions for MCTD and SLE. This procedure was replicated in the present research with a sample of largely African American and Hispanic patients. Results verified separate dimensions for MCTD and SLE, which suggests MCTD is a separate disease from SLE.

The classification of rheumatic diseases is challenging because these diseases have protean and frequently overlapping clinical and laboratory manifestations. This problem is typified by the difficulty of classification and differentiation of two prototypic multi-system autoimmune diseases, Systemic Lupus Erythematosus (SLE) and Mixed Connective Tissue Disease (MCTD). The researchers submitted medical risk factor data represented by instrument or laboratory measures and physician judgments (12 key features for SLE) from 43 patients diagnosed with SLE and 12 key features for MCTD from 51 patients diagnosed with MCTD to the WINSTEPS Rasch analysis program. Using Rasch model parameterization, and fit and residuals analyses, the researchers identified separate dimensions for MCTD and SLE, thereby lending support to the position that MCTD is its own separate disease, distinct from SLE.

N In English, the {D} morphemes are found in the past tense inflection of regular verbs, in past participles, and in -ed adjectives. The endings are spelled with -ed (or -d or -ied), but there are actually three different pronunciations, the distribution of which is phonologically conditioned. The stem-final sound determines the distribution of the allomorphs in the following manner: /id/ occurs after alveolar plosives, that is, /t, d/; /d/ after voiced sounds other than /d/; and /t/ after voiceless sounds other than /t/. The {Z} morphemes are found in the possessive inflection, in plural inflections of regular nouns, and in third-person singular verb inflections. All these forms are spelled with -s (or -'s, -s', -es, or -ies), but there are actually three different pronunciations, the distribution of which is also phonologically conditioned. The stem-final sound determines the distribution of the allomorphs in the following manner: /s/ occurs after voiceless nonsibilants; /z/ after voiced nonsibilants; and /iz/ after sibilants, that is, /s, z, , ,, , j/. Dickerson (1984a) claims that the English allomorphs must be systematically taught to second language learners and proposes the use of different allomorph choice rules based on spelling, which is accessible to all learners. In the research reported here, Dickerson's allomorph choice rules were used as the experimental treatment.

Sentence-combining exercises were systematically presented to an experimental group of L2 freshman composition students. Data from a test assessing sentence-combining and an analytical composition scoring scheme were collected from the experimental group and a control group. The research hypothesis that the experimental group who received sentence-combining exercises would write better compositions and perform better on the sentence-combining test than the control group who didn't receive sentence-combining exercises was not fully con firmed. Several factors which might explain the findings are discussed.

The goals of this study were threefold: (1) to provide a comparative analysis of five different item analysis indices using both IRT and non-IRT indices; (2) to describe the characteristics of flagged items; and (3) to investigate the appropriateness of logistic regression as an item analysis technique for further studies. The performance of five item analysis indices was examined in this study; p-value, point-biserial correlation, Rasch b parameter, Rasch χ2 fit and χ2 from the logistic regression model. A factor analysis indicated that the first factor was a difficulty factor and included the Rasch b and p-value indices, whereas the second factor represented the discrimination power of an item and consisted of the Rasch χ2 fit, χ2 from the logistic regression and the point-biserial correlation. There was a tendency for difficult items to exhibit more unusual response patterns. The χ 2 from the logistic regression fit was found to be an appropriate index when a researcher is attemp...

In this position paper, we advocate that advancements made in other disciplinary areas such as neurolinguistics should be included into contemporary reading comprehension courses and programs. We present findings from neurobiology of reading that suggest explanation of certain reading behaviors: (1) the differences between reading disability and typically developing readers; (2) an inverted U-shaped function that reflects the fact that learning to read is associated with increased activation (the rising part of the inverted U) and activation decreases are associated with familiarity, experience, and expertise (the falling part of the inverted U); (3) and, the identification of reading networks. As potential pedagogical implications of neuroimaging studies to reading, a list of sentence structures is proposed as an example to further relate reading comprehension to cognitive capacity limits.

This paper proposes a literature-based composition course for advanced Non-native English Speaking (NNES) students in an English for Academic Purpose (EAP) program and provides a rationale, a syllabus, and some suggested pedagogy for consideration. The principal reasons for choosing a literature-based format include the following: (1) extended writing about a text, or texts, should lead to reading comprehension improvement; (2) culturally responsive literature should enhance engagement; (3) reading literature, as writerly reading, will assist NNES students with developing strategies applied to reading-to-write tasks and to integrated writing skills; (4) reading for writing (RFW) will expose NNES students to a wide range of genres, syntactic constructions, discourse structures, and words and word families; (5) RFW should lead to the development of multiple-documents literacy; and (6) contemporary writing models incorporate reading as a component of the composing process, which emphas...

There is a robust tradition of program evaluation in the field of testing and measurement, but within the TESOL community, pro gram evaluation has only recently begun to be considered as a vital component. To identify some of the major concepts involved, we provide an overview of the better known approaches in program evaluation and, where applicable, focus attention on related measurement issues. We attempt to relate the following to ESL pro grams: formative and summative evaluation, criterion-, growth-, and norm-referenced evaluation, and related psychometric considera tions.

Item responses on a multiple-choice reading comprehension test from 88 ESL subjects were submitted to classical test item analyses and the Rasch one-parameter latent trait model. The Rasch model identified more misfitting items than the classical item analyses and allowed the researchers to plot the reading comprehension items at their calibrated positions along the lines of the latent trait. The trait was defined at the easy end by items that assess literal comprehension and inference of explicit details and at the difficult end by items that assess multiple string inferences. The Rasch model also indicated that additional items were needed at both ends of the difficulty continuum, if subjects in those ranges are to be discriminated properly.
