Insight for Teacher Preparation Program Administrators: Enhancing Pre-service Educators’ Intercultural Sensitivity and Deep Proficiency in Culturally Responsive Teaching through Short-term Study Abroad

Teacher preparation program administrators face the issue of expanding curricula to prepare teacher candidates for the diverse population of students they will encounter (Trent, Kea, Oh, 2008). Globalization demands that teacher candidates grasp how to function in a more integrated and interdependent society (McGrew, 2005). According to Smith-Davis (2004) students from non-English speaking countries compose the fastest growing United States K-12 student population, and those identified as limited English proficient were over 10 million in 2004. The United States Census reported in the \u27\u27New Census Bureau Report the number of individuals five and older who speak languages other than English at home more than doubled in the past three decades (2010). If teacher preparation program leaders fail to prepare future educators with the dispositions, knowledge, and skills necessary to meet the needs of the nation\u27s school population, the national security and economic development may be hindered, and the position of the United States in the world community may be challenged (Zanh, 2011). Teacher preparation program leaders are faced with how to strengthen teacher candidates\u27 level of intercultural sensitivity and to prepare them to implement culturally responsive pedagogy through course content and other activities (Lin, Lake, & Rice, 2008, p. 188). Integrating multicultural education throughout all courses instead of adding a stand-alone course dedicated to cultural awareness and instruction is one manner to enhance candidates\u27 level of intercultural sensitivity, and this means is supported by many researchers (Cochran-Smith, Davis, & Fries, 2004). Another way to heighten intercultural sensitivity and gain skill in delivering culturally-responsive teaching strategies is through cross-cultural experiences (Foster, 1995; Gay, 2000; McAllister & Irving, 2002; Nieto, 2006). One such cross-cultural experience that deans, department heads, and faculty may explore is short-term study abroad. Short-term study abroad is more affordable and attractive to university students who cannot or will not commit to a semester or yearlong study abroad experience (Donnelly-Smith, 2009). As defined by Donnelly-Smith (2009), short-term study abroad experiences are those where students participate for fewer than eight weeks. These experiences have the potential of positively impacting teacher candidates\u27 intercultural sensitivity (Lawton et al., 2006). DonnellySmith stated that little formal research was displayed in the literature that described study abroad outcomes (2009). The purpose of this paper is to reveal how a short-term study abroad experience affected teacher candidates from a Texas regional university, and thus enhanced their intercultural sensitivity and deepened their knowledge and skill in culturally-responsive teaching strategies. This study was unique from other studies presented in the literature because the focus was how another country implements early childhood education and prepares future teachers. Teacher candidates were afforded an opportunity to compare Italy\u27s early childhood education system to the system they were more familiar with in the United States

Computation in Classical Mechanics

There is a growing consensus that physics majors need to learn computational skills, but many departments are still devoid of computation in their physics curriculum. Some departments may lack the resources or commitment to create a dedicated course or program in computational physics. One way around this difficulty is to include computation in a standard upper-level physics course. An intermediate classical mechanics course is particularly well suited for including computation. We discuss the ways we have used computation in our classical mechanics courses, focusing on how computational work can improve students' understanding of physics as well as their computational skills. We present examples of computational problems that serve these two purposes. In addition, we provide information about resources for instructors who would like to include computation in their courses.Comment: 6 pages, 3 figures, submitted to American Journal of Physic

Closed form solution for a double quantum well using Gr\"obner basis

Analytical expressions for spectrum, eigenfunctions and dipole matrix elements of a square double quantum well (DQW) are presented for a general case when the potential in different regions of the DQW has different heights and effective masses are different. This was achieved by Gr\"obner basis algorithm which allows to disentangle the resulting coupled polynomials without explicitly solving the transcendental eigenvalue equation.Comment: 4 figures, Mathematica full calculation noteboo

Historic genetic structuring and paraphyly within the Great-tailed Grackle

The Great-tailed Grackle (Quiscalus mexicanus) and Boat-tailed Grackle (Q. major) are sister species that have expanded their ranges during historical times. This expansion has created an area of sympatry between these species in Texas and Louisiana, and between distinctive Great-tailed Grackle subspecies in the southwestern United States and northern Mexico. We investigated the evolutionary histories of both species using mitochondrial DNA sequence data and modern phylogenetic methods. Our results reveal genetic structure within Great-tailed, but not Boat-tailed Grackles. Great-tailed Grackles are separated into two clades, but range expansion in the north has led to secondary contact between them. Boat-tailed Grackles are monophyletic and are embedded within the Great-tailed Grackle assemblage, rendering the latter paraphyletic. These results reveal a complex phylogeographic pattern caused by recent range expansion and secondary contact of once allopatric units

Review Article RAS in Pregnancy and Preeclampsia and Eclampsia

Preeclampsia is a common disease of pregnancy characterized by the presence of hypertension and commitment of many organs, including the brain, secondary to generalized endothelial dysfunction. Its etiology is not known precisely, but it involved several factors, highlighting the renin angiotensin system (RAS), which would have an important role in the origin of multisystem involvement. This paper reviews the evidence supporting the involvement of RAS in triggering the disease, in addition to the components of this system that would be involved and how it eventually produces brain engagement

Demonstrating the Central Limit Theorem Using MATLAB

In this paper MATLAB is used in a demonstration of the central limit theorem (CLT). MATLAB is a powerful computer program used in educa­tion and industry. MATLAB allows us to increase the sample size and not sacrifice speed of computation while demonstrating the basic concept of the CLT as it applies to probability and statistics. We will give its history as well as a clear understanding of its power. In addition to reproducing previous work[l], we will provide the MATLAB code used to perform further dem­onstrations. Our program will select 30 integers between one and six, as in Lazari et. al. It will then compute each individual mean (L1) and store it in a list (L5) while repeating itself n times, where n is the total number of en­sembles. Upon completion, distribution plots are obtained for then means as well as a combined histogram for each individual (L5). For a very large n, the program does indeed demonstrate that the distribution of the sample means is really normal as in Lazari et al

UNIFIED STUDY OF THE CLASSICAL HALL EFFECT

Germanium (Ge) samples with different doping types, acceptors (p-type) and donors (n-type), were studied to investigate charge carrier behavior. Carrier concentrations were found to be 1.16×10^21 m^(-3) for the p-type sample and 7.337×10^20 m^(-3) for the n-type sample. These experiments were conducted for the standard Hall effect (Hall voltage versus low magnetic field (B) values) as well as conductivity and Hall voltage versus temperature for different B-fields. The measurements versus temperature at zero-field allow us to obtain band gap ( Eg). While we investigate the conductivities for n-type and p-type doped samples, we also study the conductivity of an undoped Ge sample from which we obtained an energy gap of Eg=0.651eV which compares well with the known value of 0.67eV at room temperature. While it is commonly known that the classical Hall voltage is linear with B-fields, not so common is the behavior of the classical Hall voltage with temperature, especially for both n-type and p-type samples. Thus, we derive a general Hall voltage formula for semiconductors that unifies the understanding of both n-type and p-type carriers. Our experimental results are analyzed with the unified theory using MATLAB. An example MATLAB program is also included to perform calculations with our unified Hall voltage expression
