Education research over the last few decades has focused on the debate over which classroom pedagogies best encourage learning: teacher-centred or student-centred. Although research appears to support the philosophy that student-centred teaching provides for better learning, the supporting research is frequently limited to observational studies or limited in experimental design. Despite this, the trend has been to encourage teachers to adopt a more student-centred approach both in the teaching of the course material and as a model for future teachers. A pilot study was conducted in an introductory university statistics course using a Latin Square Design to experimentally collect both quantitative and qualitative data pertaining to student performance. The purpose of this study was to examine the impact of teaching style on learning, assess these approaches in quantitative courses, and establish protocols for such studies using a statistically controlled design.

Filamentous black yeasts from the genus Exophiala are ubiquitous, opportunistic pathogens causing both superficial and systemic mycoses in warm- and cold-blooded animals. Infections by black yeasts have been reported relatively frequently in a variety of captive and farmed freshwater and marine fishes. In November 2012, moribund and recently dead, farm-raised Atlantic Halibut Hippoglossus hippoglossus were necropsied to determine the cause of death. Histopathology revealed that three of seven fish were affected by a combination of an ascending trans-ductual granulomatous mycotic nephritis, necrotizing histiocytic encephalitis, and in one fish the addition of a fibrogranulomatous submucosal branchitis. Microbial cultures of kidney using selective mycotic media revealed pure growth of a black-pigmenting septated agent. Application of molecular and phenotypic taxonomy methodologies determined that all three isolates were genetically consistent with Exophiala angulospora. This is the first report of E. angulospora as the causal agent of systemic mycosis in Atlantic Halibut.
