Dilemmas of difference,inclusion and disability: international perspectives on placement

This paper reports findings about placement questions relevant to disability in education. It is part of a larger international study of the perspectives of 132 education practitioners and administrators in England, the USA and The Netherlands to several dilemmas of difference. Participants were interviewed about their perspectives to a presented placement dilemma about the consequences of having inclusive/separate placements for children with more severe disabilities/special educational needs. The data are presented in quantitative terms (degrees of recognition and resolution of dilemma) and qualitative terms (reasons, justifications and suggested resolutions). The findings show the continued recognition of this dilemma and commonalities in the resolution of the dilemma across the countries. Variations in responses to the dilemmas that relate to national differences are also discussed.     

Winfield High’s Homeroom Project in International Understanding

Advanced Placement (AP) Chemistry and the National AP Chemistry Examination are both critical to secondary level institutions nationwide. The use of a national embossing stamp to attest to successful completion of an AP Chemistry course and exam to ensure college credit is a novel idea worth consideration. Moreover, the concept could be expanded to all AP science disciplines conducting laboratory exercises.     

Internet Learning Connections Between Second-Graders and University Teacher Education Electronic Mentors

SUMMARY

The dynamic nature of technology integration requires making many more connections than simply an electronic connection. This case study documents other necessary links in establishing Internet learning connections between second-graders and university teacher education students. Connections also include: collaborating with university and public school colleagues, seeking funding to implement innovative online projects, integrating content learning and literacy development with technology skills, and utilizing non-traditional teaching strategies such as electronic mentoring and e-mail exchanges to encourage young children to make the reading/writing connection. Project CONNECT represents the first attempt for primary grade online learning in the Louisville City School System, Louisville, Ohio, and the first venture for cyberfield placement for teacher education students at Youngstown State University, Youngstown, Ohio.     

The ‘foreign’ language teacher: negotiating the culture of a school when unfamiliar with the language of instruction

This article examines and theorises the experiences of 12 primary pre-service teachers at an Australian university, undertaking a two week professional teaching experience in Bangkok. This qualitative ethnographic study of our students’ and to some extent our own experiences draws on interviews, questionnaires and observations from the students, as well as reflective notes from two participating supervisors, and sets out to account for and understand the sources of the achievements and frustrations experienced by our pre-service teachers. The findings illustrate differences between the students’ overseas experiences and Australian-based experiences. These differences include organisational structures, teacher mentoring and cultural understandings, and the effects these had on the students. In particular, we distinguish the more readily observable structural nature of the schools in which the pre-service teachers were teaching, and the less visible cultural aspects that underlie these structures. We propose ways of helping students, as part of pre-departure briefings, to become more aware of these cultural underpinnings, with a view to helping them become more at ease negotiating intercultural workplaces.     

Non-iterative pole placement technique: A step further

This paper comes back to the hard problem of pole placement by static output feedback: let a triplet of matrices {A;B;C}∈R^n×n×R^n×m×R^p×n be given, find a matrix K∈R^m×p such that the spectrum of A+BKC equals a specified set. More precisely, this article focuses on the derivation of non-iterative techniques, based upon the notion of eigenstructure assignment, to solve the problem, especially when Kimura's condition does not hold. Some solutions can sometimes be found.     

Higher education students registered with disability services and practice educators: issues and concerns for professional placements

Introduction: The number of students with disabilities accessing Higher Education Institutions (HEIs), including professional courses, has increased substantially within the Republic of Ireland over the past 10 years [AHEAD (Association of Higher Education, Access, and Disability) 2012. “Survey on the Participation Rates of Students with Disabilities in Higher Education for the Academic Year 2011/2012.” http://www.ahead.ie/userfiles/file/PR_2012.pdf]. In one HEI in the Republic of Ireland, it was noticed that there was a large increase in students with disabilities, from 67 in 2006 to 259 in 2013 on professional courses. The aim of this study was to identify the issues and concerns of practice educators (PEs) in both supporting students with disabilities and exploring the concerns for students with disabilities on professional courses. Methods: A survey design was employed to meet the aims of this study and ethical permission was granted from the Faculty of Health Science Ethics Committee. Results: Respondents included 68 PEs and 63 students with disabilities. PEs were found to be concerned with students reaching the required standard of proficiency on placement, and how to support students in this. Students on the other hand identified stigma and disclosure of a disability as a concern. Conclusion: This study highlighted a difference in perceptive between PEs and students with disabilities in relation to disclosure and support needs for their disabilities.

数字化战略：地方高校图书馆“专升本”的发展定位

对地方高校图书馆来说,“专升本”既是一次绝佳的发展机遇,又是一次严峻的挑战。图书馆的发展定位包括两个方面,即图书馆的发展理念和发展阶段。其中,发展阶段在发展定位上处于主导地位。传统型、传统主导型、现代主导型和数字型这四种类型的图书馆体现的是一个呈“阶梯形”上升的发展过程。从传统型图书馆向数字型图书馆发展,这是地方高校图书馆发展的必然之路。     

Scales for Measuring Results of Physics Teaching

ABSTRACT

The Advanced Placement (AP) program is an educational program that permits high school students to take introductory college-level courses and receive college credit by passing a standardized end-of-course exam. Data were obtained from a statewide database of 2 high school graduating cohorts (N = 90,044). We used a series of propensity score analyses and marginal mean weighting through stratification to examine the impact of the AP program on students' academic achievement as measured by ACT scores. Results indicate that merely enrolling in an AP course produces very little benefit for students. Students who take and pass the AP exam, however, obtain higher ACT scores, even after controlling for a wide variety of academic, socioeconomic, and demographic variables. The authors conclude the article by discussing aspects of the AP program that remain unanswered.
