Views on using portfolio in teacher education

The usage of portfolio methods to document professional development in teaching is increasing in Germany, but despite its proliferation, the issue of how the effects of portfolio methods can be determined has received little attention. This paper investigates the acceptance of portfolio by the pre-service teachers (N = 144, 112 female) and the effects of portfolio on their professional attitudes and competences. In addition, N = 15 teacher educators were interviewed on their assessment of the portfolio method. Results suggest that the efficiency of the portfolio method depends both on personal competences and on the framing within the training program.     

Economic Growth and Advertising Expenditures in Different Media in Different Countries

Newspaper advertising expenditures depend more strongly on economic development than advertising spent in other media. Gross domestic product (GDP), therefore, predicts ad spending better in countries where newspapers are an important advertising medium. GDP also predicts ad spending better in countries where a larger proportion of GDP is spent on advertising. Intermedia competition, on the other hand, has little impact. In conclusion, the authors propose to distinguish three advertising cultures where ad spending follows economic development in different ways.
