If You Build It and They Still Don't Come: Effective versus Successful Alternative Teacher Preparation

The continuing shortage of special education teachers, combined with increased ideological critiques of teacher education programs, has spurred the growth of alternative models of teacher preparation. Only recently have professional standards for alternative models been proposed. This paper summarizes two years of a program based on professional standards. External influences, internal design, and implementation elements are presented. Results suggest that there is value in distinguishing between the effectiveness of alternative programs and their success.     

TRAINING OLDER AND YOUNGER ADULTS TO USE SOFTWARE

Forty‐six subjects (22 young, 24 old) received three training sessions with software (Borland's “Sidekick"). Each session lasted a maximum of S h. The fourth session was a test. Subjects were randomly assigned to two learning environments, partnered or individual, and half were given a computer “jargon” sheet before training. All instructions were written, learning was self‐paced, and tasks were formulated according to discovery‐method guidelines. Attitudes toward computers were measured before Session 1 and on completion of Session 3. The results showed that older adults took twice as long as younger ones but achieved nearly equal performance levels, exceeding young adults in one condition but falling slightly below them in others. Older adults requested help two to three times as frequently. Session 3 attitude scores were positively correlated with the mark achieved on the final test, and changes in attitudes were related to training conditions.     

The Influence of technologies on financing options

Abstract

International higher education is a major source of revenue in many developed countries. Historically the top destination countries for international students have included USA, UK, France and Australia. The key countries where most international students are recruited from include China, India and other parts of Asia. The extant literature has mostly examined the factors influencing international students to study in Western countries. A new trend is now emerging with an accelerating growth of international students in countries such as China and other parts of Asia. This mixed-methods study addresses the gap in the literature by exploring the factors that influence international students’ choice to study undergraduate or postgraduate courses in China. The study found that China is becoming an important destination choice for international students due to the distinctiveness of the Chinese language, the rise of its universities in global rankings and the country’s economic growth.     

Preparing pre‐service secondary education majors for inclusive classrooms in the USA

This study serves as a pilot study for a longitudinal study that will be conducted a year later. The purpose of this research is to determine how a course in special education has impacted secondary general education pre‐service teachers’ attitudes towards individuals with disabilities, teaching students with mild disabilities and the degree of their preparedness (self‐reported) in working with students with disabilities. Forty‐two secondary pre‐service teachers’ reflection papers written at the beginning and end of a mandatory special education course (16 weeks) were analysed using qualitative methodology. The findings supported our research hypothesis that a course in special education with necessary components (i.e. introductory special education knowledge, activities designed to enhance students’ dispositions toward students with disabilities, and instructional strategies that will help general education teachers teach students with mild disabilities at the middle and secondary levels more effectively) can be effective in preparing secondary education pre‐service teachers to work in inclusive classrooms.     

Sex-related differences on objective tests among undergraduates

Objective tests, such as multiple-choice and relationship analysis questions, are often used in mathematics to assess certain ranges of skills and abilities. This article examines the performance of men and women students in mathematics at university level and shows that there are significant differences between the sexes.     

Reasoning about data in middle school science

This case study illustrates instruction in an urban 6th‐grade classroom in which students were learning about mass, volume, and density by attempting to layer (stack) three miscible solutions with differing densities atop one another. The study examines classroom discourse and interaction on the basis of four teaching goals: (a) reaching consensus about which stacks were possible, (b) developing persuasive arguments that separated data from noise, (c) establishing social norms for collective inquiry, and (d) appreciating the epistemological status of scientific knowledge. The study traces the fate of three stacks that students claimed were possible after initial investigations with the solutions. These claims underwent a process of collective validation in which consensus without coercion was the goal, which illustrates emergent standards for backing claims with evidence, as well as for replicability, among the students. Students were successful in achieving three of the four goals, with some qualifications. In relation to Goal 3, which required generalization to other situations, somewhat less success is reported. Limitations in the current standards, difficulties of time allotment in current curricula, and establishing classroom cultures of inquiry are discussed. © 1999 John Wiley & Sons, Inc.

Sub-nanomolar detection of thrombin activity on a microfluidic chip

Bioluminescence resonance energy transfer (BRET) is a form of Förster resonance energy transfer. BRET has been shown to support lower limits of detection than fluorescence resonance energy transfer (FRET) but, unlike FRET, has not been widely implemented on microfluidic devices for bioanalytical sensing. We recently reported a microscope-based microfluidic system for BRET-based biosensing, using a hybrid, high quantum-efficiency, form of BRET chemistry. This paper reports the first optical fiber-based system for BRET detection on a microfluidic chip, capable of quantifying photon emissions from the low quantum-efficiency BRET² system. We investigated the effects of varying core diameter and numerical aperture of optical fibers, as well as varying microfluidic channel design and measurement conditions. We optimized the set-up in order to maximize photon counts and minimize the response time. The optimized conditions supported measurement of thrombin activity, with a limit of detection of 20 pM, which is lower than the microscope-based system and more than 20 times lower than concentrations reported to occur in plasma clots.
