The methodological approach was the action research model where the process of producing news was followed from selecting news to reflecting on their learning outcomes. The knowledge from the pilot study is useful in designing active projects within the scope of media literacy. One of the learning outcomes for the girls in this study was the awareness of how news programs in TV are staged. A positive response was the initiative from one of the participating schools to start their own news project in one of the classes. A possible outcome in longer run projects is better knowledge for developing pedagogical tools in media education.展开更多

The proposed methodology includes the main figures of economic merit evaluated to each resource assessed, the sensitivity analysis on cash flow, and recommendations of investments to each energy option assessed. A study case is applied within the northwest region of Sao Paulo State （Brazil） for those renewable-energy options. Five options of renewable-energy resources were chosen to be evaluated： three ERs （energy resources） from supply side （small hydro, wind farms and sugarcane bagasse） and two ERs from demand side （replacement of incandescent lighting by fluorescent and replacement of electric showers by central heating systems）. The conclusion is that, only two assessed ERs that have received investment grade were sugarcane biomass and fluorescent lamps replacing incandescent lamps. The rest have restriction due different reasons listed.展开更多
