For most people design is a mystery. The products of design are integrated into our daily lives to the point that design has become invisible to us. However. what is subsumed in design practice is a creative problem-solving process that is applicable as a teaching strategy as well as a method for teaching the subject of design. The purpose of this study was to inquire into the current classroom practice of Ontario Visual Arts and Technological Education teachers, understand the goals of Ontario government curriculum developers, and explore the position held by the professional design community on secondary school design education. Data for this study were collected from: (a) a textual analysis of 4 Ministry curriculum documents; (b) interviews with JO stakeholders; (c) unobtrusive observations and informal conversations conducted at 7 secondary school open house events; and (d) observation of 2 sessions of an AQ course for Design and Technology. The research design modeled the design process and was divided into 2 parts: a discovery or problem-finding phase and a discussion or problem-solving phase. The results showed that design is misunderstood and misused; it has become lost between visual arts and technology where neither program holds responsibility for its delivery; students mistake working on computers for design practice; and while there is a desire within the professional community to have a voice in secondary school design education. there is no forum for participation. The technology-driven paradigm shift taking place in society today calls for a new framework for tellching and practicing dcsign. Further research is required; howcvcr. in the meantime. secondary school educators might benefit from professional development and classroom support from the professional dcsign community.

The effects of metiram (Polyram 80 DF) on the growth of Venturia inaequalis, cause of apple scab, and the degradation of metiram were examined in culture media. Samples of V. inaequalis conidia were collected from nine orchards in 1998 and six orchards in 1999 and tested for sensitivity. Samples were plated on water agar amended with metiram or mancozeb. Mean EC50 values (effective concentration of fungicide required to inhibit germination of half the conidia) for each population were calculated. The mean EC50 values for metiram ranged from 0.26 - 1.20 ^ig metiram a.i./ml, with differences (Student Newman Keul's Test (SNK), a=0.05) between populations. EC50 values for mancozeb ranged from 0.06 - 0.58 which were also different (SNK, a=0.05). Five of these populations were examined for mycelial growth sensitivity to metiram by testing 30 monoconidial isolates from each population on metiram amended potato dextrose agar. Mean EC50 values for populations were calculated and ranged from 3.44-5.94 |ig metiram/ml, and showed differences (Friedman Test, a=0.05). As the EC50 values obtained are far less than the concentrations applied in the field, results indicate that Ontario populations of V. inaequalis are still sensitive to metiram and mancozeb. The stability of metiram in PDA at 22°C was studied over a 10-day period. The initial concentration of metiram decreased by approximately 50% within the first day, and continued to decline slowly, to approximately 20% of the initial concentration. The factors possibly affecting initial metiram degradation, including agar, heat, and the use of glass or polystyrene Petri dish composition were examined. The effects from the polystyrene in the Petri dish composition were negligible, however more studies must be done to examine metiram degradation during the first 24 hours of preparation.
