Estudo da Influência da Granulometria das Areias no Desempenho de Rebocos de Cimento Portland Normal

Os agregados para a indústria da construção civil são as matérias-primas mais consumidas no mundo, pelo que o estudo e conhecimento das suas características e consequente influência sobre as propriedades das argamassas assumem uma considerável importância. A escolha do tipo de areia e a sua composição granulométrica têm uma grande influência no comportamento das argamassas. Utilização de areias com diferentes constituições granulométricas constitui uma forma de introduzir consideráveis alterações nas características das argamassas. Torna-se então importante compreender de que modo, a variação deste simples factor, pode influenciar as características desejadas para as argamassas utilizadas no revestimento.

Adapting the Process Writing Approach to English Language Learners with Special Needs: Using Visuals

The available literature on the writing characteristics and best practices to teach writing to English Language Learners who also present some disability is scarce. In order to understand and provide some insight on the developments in this field, I propose an adaptation of the Process Writing Approach based on a literature review of the existing bibliography about the writing characteristics of English Language Learners, Special Needs Learners, and English Language Learners with Special Needs’ writing, the effects of the Process Writing Approach in teaching writing to these groups, and the use of visuals in writing instruction. The main assumptions of this study are: a) The Process Writing Approach provides an opportunity to differentiate instruction to ELLs with special needs and gives them additional opportunities to bring their funds of knowledge to the classroom, improving their writing, and b) By allowing students to rely on visuals in different phases of the writing process teachers will be addressing the needs of both visual and verbal learners, therefore allowing students more options to develop writing skills. The main pedagogical implication is that by dividing writing in recursive stages and inserting visuals as scaffolding throughout the entire writing process, teachers will provide an alternative approach to writing instruction that may be more effective to English Language Learners with Special Needs.
