Developing and Assessing Curriculum on the Physics of Medical Instruments

Undergraduate educational settings often struggle to provide students with authentic biologically or medically relevant situations and problems that simultaneously improve their understanding of physics. Through exercises and laboratory activities developed in an elective Physics in Biomedicine course for upper-level biology or pre–health majors at Portland State University, we aim to teach fundamental physical concepts, such as light absorption and emission and atomic energy levels, through analysis of biological systems and medical devices. The activities address the properties of electromagnetic waves as they relate to the interaction with biological tissue and make links between physics and biomedical applications such as microscopy or laser eye surgery. We report on the effect that engaging students in tasks with actual medical equipment has had on their conceptual understanding of light and spectroscopy. These initial assessments indicate that students’ understanding improves in some areas as a result of taking the course, but gains are not uniform and are relatively low for other topics. We also find a promising “nonshift” in student attitudes toward learning science as a result of taking the course. A long-term goal of this work is to develop these materials to the extent that they can eventually be imported into an introductory curriculum for life sciences majors.     

UNIVERSITY AUTONOMY AND QUALITY ASSURANCE

The question of university autonomy is posed and examined from a number of points of view, beginning with a short historical survey of the concept and its application. It is linked to academic freedom, to problems of centralization versus decentralization, to the internal organization of universities, to the role of universities in rapidly changing societies, to democratization, and to societal expectations with regard to universities. If university autonomy is essential for the proper functioning of universities, then quality control and management are essential prerequisites for autonomy.     

Preservice teachers’ blogging: collaboration across universities for meaningful technology integration

ABSTRACT

The purpose of this study was to explore technology integration by preservice teachers (PSTs) through collaborative blogging between two universities. Researchers aimed to learn more about the ways PSTs apply and integrate technology into classrooms. As digital natives, many PSTs assume that because they already know how to use technology personally, they can also teach using technology. However, learning to integrate technology effectively in educational settings is a challenge. This two-phase qualitative study analyzed blogging between PSTs (n = 83) enrolled in elementary teacher education courses in two different regions of the United States. Data sources included anecdotal records, PST blog post and replies, PST and elementary student technology project artifacts, and questionnaires. The data revealed three themes related to technology integration by PSTs: (1) collaborating in an online community expanded professional learning, (2) PSTs demonstrated shifts in purposes, use of digital tools, and self-efficacy when learning to integrate technology, and (3) blogging served as a conduit for meaningful technology use. Findings show that collaboration through blogging with peers outside the walls of a university classroom was a catalyst for meaningful technology integration.     

Supporting Self-Regulated Learning for College Students with Asperger Syndrome: Exploring the “Strategies for College Learning” Model

In this study, I piloted the feasibility, effects, and perceived acceptability of a peer mentoring intervention targeting academic achievement and self-regulated learning (SRL) for three college students with Asperger syndrome. The approach, dubbed Strategies for College Learning (SCL), features individualized assessment of academic performance in target courses and direct instruction of learning and self-regulation strategies under the provision of a peer mentor. The pilot study resulted in successful implementation of SCL and the acquisition of numerous learning strategies among participants. Qualitative data indicated participants felt SCL was both useful and acceptable. As the incidence of autism spectrum disorders increases, so has the need to accommodate students with highly individualized learning needs. The pilot is among the first to explore peer mentoring as an approach at bolstering SRL and academic achievement for college students with Asperger syndrome. The limitations of the study are discussed as well as implications for future research and practice.     

An investigation of the stability and variability in young children's self-regulated learning behaviors in kindergarten

The authors examined the relative stability and variability of self-regulated learning (SRL) in kindergartners across various contexts (teacher-directed activities, small-group work, and independent work). They assessed the role of temperament and context on children's use of SRL while seeking to identify if there are optimal contexts for promoting SRL in particular children. The results revealed that although temperament was not related to SRL, children's regulation strategy usage was heavily dependent on context, contradicting the idea that children are either high or low self-regulators. The relative stability of SRL varied by child, with some children showing more sensitivity to context than did others. Optimal contexts for eliciting SRL also differed by children, with some children exhibiting elevated regulation during small-group activities and others during teacher-directed activities.     

Development and validation of a method to directly measure the cable force during the hammer throw

The development of cable force during hammer-throw turns is crucial to the throw distance. In this paper, we present a method that is capable of measuring cable force in real time and, as it does not interfere with technique, it is capable of providing immediate feedback to coaches and athletes during training. A strain gauge was mounted on the wires of three hammers to measure the tension in the wire and an elite male hammer thrower executed three throws with each hammer. The output from the gauges was recorded by a data logger positioned on the lower back of the thrower. The throws were captured by three high-speed video cameras and the three-dimensional position of the hammer's head was determined by digitizing the images manually. The five best throws were analysed. The force acting on the hammer's head was calculated from Newton's second law of motion and this was compared with the force measured via the strain gauge. Qualitatively the time dependence of the two forces was essentially the same, although the measured force showed more detail in the troughs of the force-time curves. Quantitatively the average difference between the measured and calculated forces over the five throws was 76 N, which corresponds to a difference of 3.8% for a cable force of 2000 N.     

Collaborative sense-making in print and digital text environments

This study describes the sense-making behaviors of sixth- and seventh-grade students (n = 46 dyads) as they read and discussed expository articles in print and digital formats. Most dyads approached the digital text as if it were static and linear, despite the availability of hyperlinks. Reading through (or covering) the text was the most commonly observed behavior, occurring in 89% of the coded intervals in the print condition and 76% of intervals in the digital condition. Students were observed discussing a variety of cognitive and metacognitive strategies. The most common strategies were process monitoring, summarizing, connecting, and reacting. The dyads used at least one overt sense-making strategy in about 50% of the intervals when reading the print text and about 65% of the intervals with the digital text. Previewing and progress monitoring, which serve important planning and self-regulative functions, were used more frequently in the digital condition. Regression analyses show that several collaborative behaviors were associated with text comprehension, as measured by a researcher-designed multiple choice test, in the print condition but not in the digital condition. These included word recognition monitoring (β = 1.84; SE = 0.90; p = .05), summarizing (β = 2.43; SE = 1.21; p = .05), and connecting (β = −5.20; SE = 2.06; p = .02) at the student level and attending to illustrations (γ = −7.08; SE = 2.17; p = .003) at the dyad level. In both conditions, prior reading achievement and prior knowledge were strong predictors of comprehension.     

A STRENGTHENED EUROPE AS A FACTOR IN THE INTERNATIONALIZATION OF HIGHER EDUCATION: A UNESCO VISION

Beginning with general considerations about the vocation and role of UNESCO with regard to the promotion of higher education, the article zeroes in on the specific activities of CEPES, the UNESCO European Centre for Higher Education in Bucharest, Romania. Some of these activities, which are presented in detail, involve the massive introduction of new information technologies and electronic communication links into the universities and the higher education systems of the region, particularly in eastern Europe. These will contribute greatly to the internationalization of education, one of the goals of UNESCO.     

RECOGNITION OF DIPLOMAS AND DEGREES: REPORT ON THE APPLICATION OF THE EUROPEAN DIPLOMA CONVENTION CONCLUDED UNDER THE AUSPICES OF UNESCO

The European Convention on the Recognition of Studies, Diplomas, and Degrees concerning Higher Education was adopted in 1979. Thirty‐two countries have signed it, and 28, including Australia, have ratified it. In addition to reporting on the obstacles encountered and the progress achieved with regard to adoption, this article also reports on various activities which took place and are continuing to take place as direct or indirect spin‐offs of the Convention. These include subregional conventions, bilateral agreements, meetings, and the creation of national information bodies. The role and activities of CEPES as the Secretariat of the Regional Committee for the Application of the Convention are described.     

UNVEILING THE HIDDEN INFORMATION IN CREDENTIALS: A PROPOSAL TO INTRODUCE A “SUPPLEMENT TO HIGHER EDUCATION DIPLOMAS”

As the world shrinks and becomes increasingly integrated with regard to the diffusion of technologies, the flow of educated personnel and the requirements both of higher education institutions and of employers, the twin questions of educational mobility and of mobility with regard to employment, are becoming increasingly important. A major barrier to the granting of equivalences is lack of information about the meaning and the value of academic credentials, diplomas, and degrees despite the creation of information centres in various countries and the formulation of various international equivalence agreements, including the Unesco regional conventions on equivalence and the recognition of diplomas and degrees of higher education. Programmes diversify; they undergo rapid change; there ¦ are so many exceptional cases, that general information devices cannot keep up to date. What the authors propose and describe is a supplement to be granted with each diploma, the items within it being sufficiently standardized so as to make the value of each corresponding diploma and credential transparent enough to facilitate the granting of equivalences.
