Evaluating the impact of dyslexia laws on the identification of specific learning disability and dyslexia

Dyslexia is a specific learning disability that impacts word reading accuracy and/or reading fluency. Over half of the states in the USA have passed legislation intended to promote better identification of individuals with dyslexia. To date, no study has been conducted to investigate the potential impact of state laws on the identification of specific learning disability (SLD), and limited data has been presented on the rate at which students in public school settings are identified with dyslexia. The first aim of the current study was to determine if any detectable changes in the identification rates of SLD have occurred in states implementing dyslexia laws because most states do not report number of students identified as dyslexic but rather those students identified with an SLD. The second aim of the study was to characterize the rate of identifying dyslexia in the two states (Texas and Arkansas) that require public schools to report the number of students identified with dyslexia. The third aim was to characterize the identification rate across first to 12th grades. Current SLD rates range from 3.2 to 8.5% in all 50 states. Analysis of SLD prevalence rates did not vary between states with and without dyslexia laws in place. Moreover, there was no change in the identification of SLD once states had implemented these laws. Rates of dyslexia in Arkansas and Texas were less than 5%. Given the persistent levels indicating lack of reading proficiency, our review of data suggests that overall students with dyslexia are being underidentified.     

Returning after taking a break in online distance higher education: from intention to effective re-enrollment

One of online distance learning’s positive attributes is its flexibility. However, the possibility of engaging in periods of non-enrollment (breaks) usually ends in students dropping out. In this paper, the intention to continue of those students who have not enrolled in the second semester is analyzed, adopting a long-term program perspective. This continuance intention is compared with the subsequent restart (or dropping out) in the third semester. This analysis has confirmed that the models of continuance intention and effective re-enrollment are essentially different. Continuance intention is more rational, even logical, and is mainly based on the level of satisfaction or dissatisfaction with the educational experience (difficulty of the learning materials or perception of the learning system). Effective re-enrollment is more practical or pragmatic, with more importance given to the effects of student dimension variables, for example, motivations for studying, previous university experience, or environmental variables, such as having a job.     

Academic Expectations of Australian Students from Aboriginal,Asian and Anglo Backgrounds: Perspectives of Teachers,Trainee-teachers and Students

There are ethnic group differences in academic achievement among Australian students, with Aboriginal students performing substantially below and Asian students above their peers. One factor that may contribute to these effects is societal stereotypes of Australian Asian and Aboriginal students, which may bias teachers’ evaluations and influence student outcomes. A questionnaire assessing academic expectancies for hypothetical students from different ethnic groups was administered to 55 experienced teachers and 144 training teachers. A measure of self-expectancies and group expectancies was administered to 516 school students. The findings revealed that Asian students were expected to perform better in mathematics and expend greater effort than Aboriginal and Anglo-Australian students. In turn, there were higher expectancies for mathematics performance for Anglo-Australian students compared with Aboriginal students. We discuss the potential implications of these stereotypes for students’ school achievement, particularly the risk that negative implicit stereotypes might result in these students being directed to special education.     

The effect of deloading tape on medial gastrocnemius muscle fascicle behaviour during dynamic exercise

This study examined the effect of diamond deloading tape on medial gastrocnemius (MG) muscle behaviour during exercise in healthy adults (n = 27). A randomised cross-over trial assessed the effect of tape (no-tape, sham-tape and deload-tape) on ankle and MG fascicle kinematics during three heel raise-lower exercises [double leg (DL), single leg (SL) and loaded single leg (LSL)]. There was no effect of tape on standing fascicle length (FL) or pennation angle (PA), or ankle or knee joint angle. There was a significant effect of tape on ankle kinematics for all exercises. Both the deload-tape and sham-tape resulted in less ankle plantar flexion but had no effect on dorsiflexion. There was a significant effect of tape on FL change for the SL and LSL exercise. Compared to no-tape, the deload-tape resulted in less fascicle shortening during ankle plantar flexion, and more fascicle lengthening during ankle dorsiflexion. For the LSL exercise, deload-tape caused MG fascicles to operate at longer lengths, for a given joint angle. Diamond taping, with or without added tension, has only a small effect on ankle and MG fascicle kinematics during the heel raise-lower exercise. With the exception of the LSL exercise, both tape conditions resulted in similar changes in the FL-angle relations.     

Exploring individual differences as factors to maximize interactive learning environments for future learning

Identifying characteristics of individuals who will be negatively impacted by interactive learning environments (ILE) was explored in a field study conducted among learners whose high-stakes performance depended upon grasping training scenarios quickly. Gauging the appropriateness of computer-based simulations for individuals became a pedagogical theme, and examining whether the history of technology usage was a factor revealed what may negatively impact an individual’s stress and workload and therefore hinder learning. This study found that individuals reporting higher frequency of computer usage experienced more temporal demand, and reported higher virtual world usage predicted a decrease in temporal demand. Implications suggest continual development of digital literacy skills to prepare for using ILEs especially for faculty and instructors. Establishment of consistent nomenclature of virtual technology terms will improve reliability and validity of measures. Areas of future research include inquiry into digital leadership for promoting metacognition and self-efficacy.     

Alternative approaches to structural modeling of ordinal data: A Monte Carlo study

In practice, several measures of association are used when analyzing structural equation models with ordinal variables: ordinary Pearson correlations (PE approach), polychoric and polyserial correlations (PO approach), and conditional polychoric correlations (CPO approach). In the case of structural equation models without latent variables, the literature has shown that the PE approach is outperformed by the alternatives. In this article we report a Monte Carlo study showing the comparative performance of the aforementioned alternative approaches under deviations from their respective assumptions in the case of structural equation models with latent variables when attention is restricted to point estimates of model parameters. The CPO approach is shown to be the most robust against nonnormality. It is also robust to randomness of the exogenous variables, but not to the existence of measurement errors in them. The PO approach lacks robustness against nonnormality. The PE approach lacks robustness against transformation errors but otherwise it can perform about as well as the alternative approaches.     

The Electronic Cataloging in Publication Cataloging Partnership Program: A Model for Cooperative Cataloging for the Twenty-First Century

The Library of Congress’ Cataloging in Publication (CIP) Program has been in existence for forty years. During this time, the CIP Program has moved from a model where the Library of Congress created all pre-publication metadata for publishers to a partnership where other libraries share in the creation of metadata. This article documents the evolution of the Electronic Cataloging in Publication (ECIP) Cataloging Partnership Program. The ECIP Cataloging Partnership Program can be used as a model to leverage limited resources across libraries to the benefit of library users nationwide.     

What Influences Advertising Price in Television Channels?: An Empirical Analysis on the Spanish Market

Advertising has an important role in the media industry. In a context where advertising generates a negative externality for viewers, this article analyzes the factors explaining ad prices in free TV empirically. This article also considers the participation of government-owned broadcasters in the Spanish market. This study finds that private ownership is associated with higher advertising prices. The results show a positive relation between audience size and ad price and a negative relation between ad price and advertising time. In addition, this study finds that higher prices are associated with the percentage of the population between 14 and 29 years old and the regional gross domestic product per capita in the broadcast area.
