A symplectic eigensolution method in transversely isotropic piezoelectric cylindrical media

INTRODUCTION Since the phenomenon of piezoelectricity in natural crystals was discovered in 1880, it has been applied in many fields, such as smart structure, sensing devices and active control, because of its special properties. Combining electrical behavior with mechanical deformation is the special property which attracted great interest of researchers. Many models have been developed for studying piezoelec- tric effects. Dunn and Wienecke (1996) used Green’s functions for transverse…     

Improving the Acquisition of Novel Vocabulary Through the Use of Imagery Interventions

The purpose of this study was to investigate the impact of imagery interventions on the vocabulary acquisition abilities of second grade students. A total of 15 students were randomly assigned to three different intervention conditions: Word Only, which involves the simple verbal presentation of a vocabulary word; Dual Coding, in which a picture was paired with the vocabulary word, and Image Creation, in which students were told to create a mental picture of the vocabulary word in their mind and draw it on paper. These students were taught a total of 21 vocabulary words: seven animal and habitat words, seven musical instrument terms, and seven science terms. A Latin square design was used, in which each group of students rotated through each of the interventions, being exposed to a different treatment condition for each category of words. Participants were measured on the number of words they were successfully able to acquire through the use of experimenter designed comprehension measures. While no statistical significance was shown between the interventions across the word categories, a significant difference was found between the Image Creation and Word Only interventions within the science terms category. Students also reported that the imagery interventions facilitated the ease with which they learned the words. The findings have implications for increasing the success of classroom instruction, specifically for presenting novel vocabulary words to early elementary learners using imagery methods.     

A tale of three campuses: Unearthing theories of residential life that shape the student learning experience

Frank Shushok Jr., T. Laine Scales, Rishi Sriram, and Vera Kidd share some initial thoughts about responses to their Campus Residential Experience Survey. Do you recognize your institution?     

Nature watch

Deer are some of the commonest, most visible, and attractive mammals in many forests and grasslands of India. They display a fascinating variety in their antlers, social systems, herd-forming behaviour, and ecology. Unfortunately, several factors have brought some species to the brink of extinction today.     

Interpersonal and relational orientation among pre-service educators: differential effects on attitudes toward inclusion of students with disabilities

The purpose of this investigation was to determine the extent to which pre-service educators’ interpersonal characteristics affected their attitudes toward teaching students with disabilities (inclusion), as measured by the FIRO-B and ATIES pre- and post-course. The FIRO-B was administered to assess expressed and wanted aspects of three interpersonal needs: personal inclusion, affection and control. The ATIES was administered to measure attitudes toward classroom inclusion of students with physical, academic, behavioral and social disabilities. Repeated measures ANOVAs revealed a main effect for wanted inclusion and an interaction effect for expressed inclusion and expressed affection on attitudes toward classroom inclusion. Ultimately, these findings reveal how unique relational characteristics may influence preparation initiatives and may encourage consideration of how individual factors may mediate teacher training and preparation.     

Using Statistical Control Charts to Analyze Data from Student Evaluations of Teaching

In this paper, a method for analyzing data from student evaluations of teaching is presented. The first step of the process requires development of a regression model for teacher's summary rating as a function of student's expected grade. Then, two‐sigma control charts for individual evaluation scores (section averages) and residuals from the regression model are used to identify both excellent and poor outcomes. The performance of an individual whose scores are out of control on both charts cannot be explained by expected grade and therefore is worthy of note.
