Spreading my wings : how can I improve my practice and contribute to the professional knowledge base through narrative-autobiographical self-study?

"How can I improve my practice and contribute to the professional knowledge base through narrative-autobiographical self-study?" Through the use of Whitehead's (1989) living educational theory and examination of my stories, I identify the values and critical events that have helped me come to know my own learning and shape my professional self. Building on the premise that educational knowledge/theory is created, recreated, and lived through educational inquiry; I strive to make meaning of this data archive, collected over 7 years of teaching. I chart my journey to reexamine my beliefs and practices, to find a balance between traditional and progressive practices and to align my theory and practice. I retell, and, thus, in some way relive, my own "living contradictions." A reconceptualization of the KNOW, DO, BE model (Drake & Burns, 2004) is used to develop strategies to align my practice, including a six-step model of curriculum design that combines the backwards design process of Wiggins and McTighe (1998), the KNOW, DO, BE model (Drake & Burns) and Curry and Samara's (1995) differentiation planner.

The effect of gregarine parasite infections, age, and diet on calling song structure and mating behaviour in the Texas field cricket, Gryllus integer

In the past ten years, many researchers have focussed their attention on parasites regarding the role they may play in causing variations in male secondary sexual traits and subsequent effects on female choice. Male age has also been suggested to be an important factor in female choice if old age reflects superior genes. This study investigated the effects that gregarine gut parasites, age, and diet have on the calling and mating behaviour of the male Texas field cricket, Gryllus integer. Male calling songs were recorded in the laboratory using a Digital Signal Processing Network. The song parameters measured were: pulse rate, pulse width, burst duration, pulses per burst, interburst interval, and percent missing pulses. The effects of parasite load and age on the various calling song parameters was investigated in crickets that were fed two different diets varying in nutritional quality. None of the calling song parameters were affected by either parasite load or age in either diet grou p. Courtship behaviour was ob served and recorded using an Eventlog recorder on an IBM computer in the laboratory. Females mated equally with paras(tized and unparasitized males and with old and young males The total duration and proportion of time spent performing each of 9 courtship displays were recorded for males on each diet. Only one display was affected by parasite load. Highly parasitized males fed the nutritionally inferior diet juddered for a proportionately shorter time than males with low parasite loads. Also, older males performed juddering and shaking antennae proportionally longer and juddering and raising wings for longer durations than younger males. Males that successfully mated were observed for performance of 8 post-copulatory guarding behaviour displays. None of the guarding behaviours were affected by parasite load. However, one display was affected by age, with older males performing guard turning for shorter durations than younger males. Results are discuss,ed in terms of the influence of parasites and age on female choice.

Personal Seals of Sir Isaac Brock

Two orange coloured seals containing the impression of the personal seal of Sir Isaac Brock. The seal depicts a crest containing a lion in the upper portion and an eagle with its wings spread in the lower portion, which represent strength, clarity of vision and courage. Below the crest is a banner with "Canada" written on it. Above the crest is an Indian on a battlement holding a tomahawk, which represents the alliance Brock had forged with the First Nations. The seals are in a John Sinclair tobacco tin.
