This study examined the effects of historical reasoning strategy instruction on 11th-grade students. Students learned historical inquiry strategies using 20th Century American history topics ranging from the Spanish-American war to the Gulf of Tonkin incident. In addition, students learned a pre-writing strategy for composing argumentative essays related to each historical event. Results indicate that in comparison to a control group (N = 79), essays written by students who received instruction (N = 81) were longer, were rated as having significantly greater historical accuracy, were significantly more persuasive, and claims and rebuttals within each argument became more elaborated. Importantly, students in the control group read the same primary and secondary source document sets, and received feedback on written essays on the same topics.  相似文献

Telenovelas have been considered the predominant popular genre on television, the most widely available and popular national medium, in Brazil, for more than 30 years (Straubhaar, 1982). However, we argue in this article that although telenovelas do indeed have this remarkable penetration and popularity in Brazil, their reception is mediated by audience class, geographical location, race, and issues with media content. Many in the audience feel disenfranchised from the dominant telenovela representations, particularly on the primary network, TV Globo, because of their rural, Northeastern status and identity, or their Afro-Brazilian identity. They question their sense of belonging, not because they do not feel Brazilian, but because the “Brazil” they see on TV does not include them.  相似文献

This study is aimed at an assessment of the properties of two polymeric products applied to Norway spruce (Picea abies) and White poplar (Populus alba) wood species. It contributes to ongoing research experiments on the consolidating properties of two synthetic resins and their potential synergic action on wood, resulting from their different interaction with the substrate: Paraloid B72 and Regalrez 1126. Experiments were carried out on a series of samples of the two wood varieties. The consolidants were applied alone and one after the other, with one coat of Regalrez and then one of Paraloid. Porosity and variations in pore size distribution were ascertained by mercury intrusion porosimetry (MIP). Colorimetric and IR spectroscopic measurements were also taken before and after aging by solar radiation and freeze/thaw cycles, to verify the possible slowing of photodegradation of the treated wood and the consolidating resistance. Results confirm that both products penetrate the wood with a different behaviour. After double treatment with Regalrez + Paraloid, a significant advantage was observed in terms of mechanical resistance and pore size distribution, although no advantages as regards resistance to photo-oxidizing processes or colour changes were observed.  相似文献
