The primary objective of this study was to implement a project that utilizes telecommunications as a tool to enhance the grade eight science curriculum. The process of becoming prepared to undertake this study was examined and documentd so that teachers in all subject areas at all grade levels could use it as a guide for similar projects. It was proposed to do this by conducting a collaborative project in which the students would use the scientific method to develop research questions that could be used to discover why the incidence of asthma is so high in Central Alberta. These questions would be sent out to schools across Canada and then the data would be analyzed and interpreted. The results would be shared with all participants as well as asthma researchers. The study met with many barriers whcih impeded the progress as well as made it impossible to fulfil the original goal of having the students collaborate with the experts and contribute their own research to the field. Whe embarking on a new project using technology it is inevitable that there will be barriers. Through repeated reconnaissance we were able to adjust our goals and still pursue very worthwile, but very different computer and telecommunications projects. The students attitudes towards learning science, science in society and computers were measured by pre and post surveys. The findings showed that the students were aware of the importance of all these factors in their lives. Without completing the asthma study, it is impossible to know how much of a difference there would have been in the results. The qualitative results showed very clearly that computers are a motivator for students. They enjoy working on them and the challenge they present. Many of them will do extra homework so that they can take advantage of every opportunity to work on the computer. Unfortunately, many teachers do not have the time or support to learn enough about the Internet/Schoolnet and what is available to take full advantage of what is has to offer our students and ourselves. For the most part, there are few teachers in each disrict becoming involved. This will change over time only if there is a support system in place and the pioneers share what they have learned. We cannot run the risk of the forerunners becoming discouraged and giving up. The Internet is a global community. For that community to grow and flourish we must share what we have learned and provide the means to make the path smoother for those who follow. Through this study, the projects have been documented and resources have been prepared that are intended to help others get online and access a wide variety of resources that are sure to enhance all programs and professional development. / xiii, 228 leaves : ill. ; 28 cm.

Three-dimensional canopy relectance models provide a physical-structural basis to satellite image analysis, representing a potentially more robust, objective and accurate approach for obtaining forest cover type and structural information with minimal ground truth data. The Geometric Optical Mutual Shadowing (GOMS) canopy relectance model was run in multiple-forward-mode (MFM) using digital multispectral IKONOS satellite imagery to estimate tree height and stand volume over 100m2 homogeneous forest plots in mountainous terrain, Kananaskis, Alberta. Height was computed within 2.7m for trembling aspen and 1.8m fr lodgepole pine, with basal area estimated within 0.05m2. Stand volume, estimated as the product of mean tree height and basal area, had an absolute mean difference from field measurements of 0.85m3/100m2 and 0.61m3/100m2 for aspen and pine, respectively. / xiii, 143 leaves : ill.

The present technological focus in education is requiring teachers to become computer-literate so that they are better able to integrate computer technology into their teaching. This thesis examines teachers' leves of computer self-efficacy (one's belief in one's ability to use computers) to see if there is a correlation with computer self-efficacy and classroom practice. Current research suggest that one can use computer self-efficacy as a way of determing teachers' levels of willingness to use computers. Based on the distribution of a computer self-efficacy scale and a questionnaire designed to identify computer technology integration into teaching, this study shows the correlation between computer self-efficacy and classroom practice in a selection of schools in southern Alberta. The finding of the research show that there is a weak correlation (r=0.405) between CSE and classroom practice; while there is a moderate to strong correlation (r=0.62) between CSE and instructional practice. Interestingly, the correlations between CSE and each of the specific classroom uses listed in the survey were extremely weak. These correlation coefficients ranged from 0.0777-0.287. Only 14/87 of the teachers surveyed have not attended a computer course. However, out of those 14 teachers only 2 do not use the computer for classroom used. On the other hand, of the 73 teachers who have attended a computer course, 16 do not use the computer in classroom teaching. For this group of teachers, participating in a computer course did not appear to have an impact on classroom practice. Moreover, the reseach found that those teachers with high levels of CSE do not necessarily teach using computers. An exploration of change literature provides a framework for understanding these results, and help place in perspective the need to rethink guidelines for professional development, teacher education and classroom practice as they relate to computers in education. / vii, 68 leaves : ill. ; 28 cm.

Forested watersheds in western North America are subject to significant change from natural and anthropogenic disturbance, including wildfire. Forest canopy changes have subsequent impacts on sub-canopy snow processes. A simple, process-based point energy balance model was developed to quantify differences in energy balance characteristics between a burned and a healthy forest stand. Potential model uncertainties were identified using sensitivity analyses. Simulated snowmelt accurately recreated measured snowmelt, providing confidence in the model’s ability to simulate energy balance processes in subcanopy environments where wind redistribution and sublimation are not major drivers of the local snowmelt energy balance. In the burned stand, sub-canopy snow accumulation was greater but melted more rapidly than in the healthy stand. The removal of forest canopy resulted in more energy available for snowmelt, including higher short-wave and lower long-wave radiation, and increased turbulent fluxes. Burned stands should be considered a separate land cover type in larger scale watershed models. / xii, 129 leaves : ill,, map ; 29 cm

There are far fewer high school students enrolled in physics than in chemistry or biology courses within the province of Alberta (Alberta Education, 2007). Students are also completing the highest level math course in larger numbers than those taking physics. It appears that a fear of physics exists within students in our province; this fear seems to be related to a level of difficulty the students associate with physics. Many students either opt to not take physics or enter the course with the expectation of failure. In this study I explored the impact of physics’ reputation upon a group of students who chose not to take physics. In addition, I attempted to determine whether the perception of the difficulty of high school physics is accurate. This was done by investigating the perceptions of several students who took physics. I surveyed students from one high school in a small urban school district using group interviews. The students were in grades 10 to 12 and divided into groups of Science 10, Physics 20 and Physics 30 students. The students were interviewed to gain a deeper understanding of what perceptions they have about physics and why they may have them, hoping to identify factors that affect their academic decision to take or not take physics classes. For the students interviewed, I found that the biggest influence on their decisions to take or not take physics was related to their future aspirations. The students were also heavily influenced by their perceptions of physics. The students who took physics claimed that physics was not as difficult as they had believed it to be and they reported that it was interesting, enjoyable and relevant. Those students who had chosen to not take physics perceived it would be difficult, irrelevant and boring. Therefore, a major difference of perception exists between the students who took physics and those that did not. / viii, 221 leaves ; 29 cm

There has been limited research on the characteristics inside the nonprofit (NP) boardroom. Much of the prescriptive NP governance literature is based on for-profit (FP) assumptions. Following a contingency approach, this multiple case-study of two Alberta organizations looks into the NP boardroom to observe the board characteristics alongside organizational and environmental contexts as proposed in a framework by Bradshaw (2009). To build on the proposed framework, this study also explored the combination of internal and external social capital. Using a pattern-matching analysis, support was found for the theorized board characteristic and social capital propositions. While limited by the cross-sectional and exploratory nature, the findings support future research. Future studies can explore the implications of such characteristics and contingencies on board effectiveness and organizational performance. / ix, 95 leaves ; 29 cm

The multiple-forward-mode (MFM) inversion procedure is a set of methods for indirect canopy relectance model inversion using look-up tables (LUT). This thesis refines the MFM technique with regard to: 1) model parameterization for the MFM canopy reflectance model executions and 2) methods for limiting or describing multiple solutions. Forest stand structure estimates from the inversion were evaluated using 40 field validation sites in the Canadian Rocky Mountains. Estimates of horizontal and vertical crown radius were within 0.5m and 0.9m RMSE for both conifer and deciduous species. Density estimates were within 590 stems/ha RMSE for conifer and 310 stems/ha RMSE for deciduous. The most effective inversion method used a variable spectral domain with constrained, fine increment LUTs. A biomass estimation method was also developed using empirical relationships with crown area. Biomass density estimates using the MFM method were similar to estimates produced using other multispectral analysis methods (RMSE=50t/ha). / xvi, 156 leaves : ill. (some col.), maps ; 29 cm.

This study investigated the influence of geomorphic context and flow regulation on cottonwood (Populus) age structure, stand size, recruitment rates, and annual radial growth patterns along the Oldman River in southern Alberta. Dendrochronological techniques were used to age trees, establish population structures, and measure annual radial growth on three reaches in differing geomorphic contexts. Cottonwoods within a narrow, 'constrained' reach were more negatively impacted by partial dewatering of the river, but responded more favorably to increased late-summer flows combined with suitable recruitment conditions than the trees within a wide, 'alluvial' reach. A positive linear relationship between early-summer peak discharge and annual radial growth was found only on the alluvial reach. However, these trees also had the slowest growth rates, likely due to competition between trees because alluvial reaches often support large, dense stands of cottonwoods. This study demonstrates the need to consider the geomorphic context when studying cottonwood responses to river regulation. / xvi, 141 leaves : ill. ; 29 cm.

On 14 February 1933, the citizens of Blairmore, Alberta, elected a Communist town council; this so-called Red administration remained in power until 1936. Best known for their seemingly outrageous actions, the council exists within current historiography as either the result of protracted depression or an example of the success experienced by the Communist Party of Canada during this period. This thesis will challenge both arguments, demonstrating that a series of social, economic, and political experiences resulted in the election of known Communists being socially permissible by 1933. It will be demonstrated that the agenda of council was not strictly “Communist,” rather it represented a balance between radical and populist programs, thus enabling council to challenge capitalist society while providing a practical response to the local effects of the Depression. The deterioration of this balance by 1936, coupled with a series of scandals, was resultant in the council’s electoral downfall. / vii, 161 leaves ; 29 cm.

Bull trout are a species of fish native to the coldwater mountain streams of Alberta. Because this species is of special conservation concern and displays finely dissected population structure, it is well suited as a model species to test the utility of versatile conservation genetics tools. One such tool, a genetic clustering method, was used to discern the hierarchical population structure of bull trout in the core of their range in South-West Alberta. The method also revealed patterns of gene flow by way of assignment tests. Populations defined by this method were then used as reference populations for mixed-migrant assignment tests, revealing that clustering method-defined populations may be more suitable for such tests rather than traditional approaches that define reference populations by sampling location. Combined with spatial data a posteriori, assignment tests had additional utility of discerning spatial scale of movement for juvenile and adult salmonids. This technique provided further evidence that assignment tests may be powerful indirect tools for evaluating migration, and that longrange inter-stream dispersal in juvenile salmonid fish may be more common than previously assumed. / xi, 174 leaves : ill. ; 29 cm. --
