In this paper, we propose the new Broyden method for solving systems of nonlinear equations, which uses the first derivatives, but it is more efficient than the Newton method (measured by the computational time) for larger dense systems. The new method updates QR decompositions of nonsymmetric approximations of the Jacobian matrix, so it requires O(n) arithmetic operations per iteration in cont...

The use of paraeducators has increased as a main mechanism to include more students with disabilities in the public schools in the U.S. Although the utilization of paraeducators is intended to be a supportive service delivery option, many concerns and challenges have resulted. The purpose of this study was to examine the role of the paraeducator in the general physical education environment fro...

“We are without allies amongst the Iraqi populace, including those who have benefited from the ouster of Saddam. . . . Across Baghdad, Latifiyah, Mahmudiyah, Salman Pak, Baqubah, Balad, Taji, Baiji, Ramadi, and just about everywhere else you can name, the people absolutely hate us. . . . The Iraqi people have not bought into what the Americans are selling, and no amount of military activity is ...

foresee a probable decrease in the number of mental defectives to be dealt with; but thought there were possibilities of a reduction in the number of physical defectives. There was an enormous and gratifying improvement in the conditions under which special education was carried on, and there could be none better than those enjoyed in some parts of Scotland. Mr. McKechnie begged all teachers to...

Recent development in the role of special education in kindergarten children includes the use of Information and Communication Technologies (ICTs). ICT nowadays is recognized as a tool that can foster the knowledge and the experiences for this crucial age and the support of specific areas in kindergarten according to the educational perspective and the areas of needs they serve is thought signi...

This paper presents novel numerical approaches to finding the secrecy capacity of multiple-input multiple-output (MIMO) wiretap channel subject multiple linear transmit covariance constraints, including sum power constraint, per antenna constraints and interference constraint. An analytical solution this problem is not known existing solutions suffer from slow convergence rate and/or high per-i...

Distributed leadership can enhance the professional learning communities of schools. The present study explored the leadership experience of Jordanian special education teachers, and their perceptions of common constraints to leadership. A mixed method design was used, including a survey (n = 136) and an interview (n = 23). Results indicated that special education teachers had little experience...

This article presents a historical review of mathematics education since the late 1950s in the United States. Three themes are used to organize the literature reviewed in the article: (a) broad sociopolitical forces, particularly highly publicized educational policy statements; (b) trends in mathematics research; and (c) theories of learning and instruction. At times, these themes coincide, as ...

A neurodevelopmental screen in the medical examination of 3750 school entrants with a mean age of 5 years 4 months was validated as a predictor of coordination and communication difficulties. Class teachers of 6, 7, and 8 year olds completed a questionnaire about motor and communication success and difficulty in school activities. Below average ratings on the neurodevelopmental screen were asso...
