Toward a more reflective teaching practice: Revisiting excellence in teaching

Excellence in teaching has always been a demanding and absorbing concern in institutions of higher learning. Earlier studies, which are numerous, have often dealt with the measurement of teacher qualities but have largely failed to explain the phenomenon of excellence in practice. This study focused on the outstanding professional teachers’ candid revelations of their subjective experiences of becoming and being excellent in their craft. Findings of the study indicated that love is the touchstone of excellence in teaching: that is, loving the students, loving knowledge and loving the teaching process.     

The Treatment of Research

The recommendations of the Dearing Report concerning research organisation and content are critically examined. Many of them are seen to be benign and to adopt an appropriately pluralist approach to the objectives and working of the higher education system. The report is criticised, however, on several grounds. The Committee had a fragile grasp of the nature of knowledge and of its modes of production, and failed to remedy this by consulting sufficiently available international and national research. It is, therefore, inadequate as an example of the way in which research on higher education should be used in determining higher education policy. It takes for granted conventional wisdom on several key issues: the application of selectivity in research funding; the priority to be given to areas identified in the still largely unevaluated Technology Foresight programmes, and the relationships between uni- and multi-disciplinary work.     

The Subordination of Local Government and the Compliant Society

The paper depicts the changes that have taken place in the relationships between the state and local education authorities from the 1980s and in the freedom of the schools and the teaching profession to create and offer the curriculum. The changes are linked to a shift from the interactive to the idealist concepts of educational development. They are placed in the context of changes in assumptions about the role of local authorities and schools in sustaining democratic and professional roles and practices, and in the growth of what can be conceived of as the increasing development of a Compliance Society.     

Student evaluations of teaching: perceptions of faculty based on gender,position, and rank

The current study explores the feelings and thoughts that faculty have about their student evaluations of teaching (SET). To assess the perceptions of SETs, all teaching faculty in one college at a western Land Grant University were asked to complete an anonymous online survey. The survey included demographic questions (i.e. gender; rank such as assistant, associate, and full professor; and positions like non-tenure track, tenure track, and tenured) as well as questions related to faculty's feelings while reading their SETs. While minimal differences were found in responses based on rank or position, several differences were found based on faculty gender. Overall, female faculty appear to be more negatively impacted by student evaluations than male faculty. These gender differences support previous research that suggests males and females receive and react differently to personal evaluation. Resultant suggestions include modifying surveys from anonymous to confidential and offering professional development training for faculty.     

Fluid and electrolyte balance in elite male football (soccer) players training in a cool environment

There are few data in the published literature on sweat loss and drinking behaviour in athletes training in a cool environment. Sweat loss and fluid intake were measured in 17 first-team members of an elite soccer team training for 90 min in a cool (5°C, 81% relative humidity) environment. Sweat loss was assessed from the change in body mass after correction for the volume of fluid consumed. Sweat electrolyte content was measured from absorbent patches applied at four skin sites. Mean (?± s) sweat loss during training was 1.69?±?0.45 l (range 1.06?-?2.65 l). Mean fluid intake during training was 423?±?215 ml (44?-?951 ml). There was no apparent relationship between the amount of sweat lost and the volume of fluid consumed during training (r ² = 0.013, P = 0.665). Mean sweat sodium concentration was 42.5?±?13.0 mmol?·?l^?1 and mean sweat potassium concentration was 4.2?±?1.0 mmol?·?l^?1. Total salt (NaCl) loss during training was 4.3?±?1.8 g. The sweat loss data are similar to those recorded in elite players undergoing a similar training session in warm environments, but the volume of fluid ingested is less.     

Curative role of pantothenic acid in brain damage of gamma irradiated rats

Radiation induced brain damage is associated with impairment of mitochondrial functions, variations in the level of neurotransmitters, and oxidative stress. Mitochondrial function is closely linked to the level of neurotransmitters since the precursors are supplied by the Kreb’s cycle intermediates. The objective of this study was to evaluate the influence of pantothenic acid, an essential component in the synthesis of Coenzyme A (CoA), on the activity of the Krebs cycle enzymes, isocitrate dehydrogenase (IDH), α-ketoglutarate dehydrogenase (α-KGDH), and succinate dehydrogenase (SDH); the level of aspartic, glutamic and GABA; the activity of transaminases, and oxidative stress, in the cerebrum of γ-irradiated rats. Pantothenic acid (26 mg/Kg) was orally administered to the rats, 2 h after irradiation and during the following 5 days. Animals were sacrificed the 7th day post-irradiation. The exposure of male albino rats to γ-rays (5 Gy) has triggered oxidative stress notified by a significant elevation in the level of malondialdehyde (MDA), an end product of lipid peroxidation, associated to a significant decrease in the content of phospholipids, and the antioxidant compound glutathione (GSH). The activity of IDH, α-KGDH, and SDH, has significantly decreased, while the level of aspartic, glutamic and GABA has significantly increased. In parallel to these changes, the activity of alanine and aspartate transaminase has significantly increased, compared to their values in the control rats. Pantothenic acid treatment, has significantly attenuated oxidative stress; enhanced the activity of IDH, α-KGDH, and SDH; minimized the increase in the level of amino acids and the activity of transaminases, compared to their values in the cerebrum of irradiated rats. In conclusion, pantothenic acid could improve the level of neurotransmitters amino acids, which depends on the enzymatic activities of Krebs cycle and linked to oxidative stress.     

Virtual Microscopy: A Useful Tool for Meeting Evolving Challenges in the Veterinary Medical Curriculum

Veterinary schools, similar to many professional health programs, face a myriad of evolving challenges in delivering their professional curricula including expansion of class size, costs to maintain expensive laboratories, and increased demands on veterinary educators to use curricular time efficiently and creatively. Additionally, exponential expansion of the knowledge base through ongoing biomedical research, educational goals to increase student engagement and clinical reasoning earlier in the curriculum, and students’ desire to access course materials and enhance their educational experience through the use of technology all support the need to reassess traditional microscope laboratories within Professional Veterinary Medical (PVM) educational programs. While there is clear justification for teaching veterinary students how to use a microscope for clinical evaluation of cytological preparations (i.e., complete blood count, urinalysis, fecal analysis, fine needle aspirates, etc.), virtual microscopy may be a viable alternative to using light microscopy for teaching and learning fundamental histological concepts. This article discusses results of a survey given to assess Professional Veterinary Medical students’ perceptions of using virtual microscope for learning basic histology/microscopic anatomy and implications of these results for using virtual microscopy as a pedagogical tool in teaching first-year Professional Veterinary Medical students’ basic histology.
