Interactive numerals

Although Arabic numerals (like {\textquoteleft}2016{\textquoteright} and {\textquoteleft}3.14{\textquoteright}) are ubiquitous, we show that in interactive computer applications they are often misleading and surprisingly unreliable. We introduce interactive numerals as a new concept and show, like Roman numerals and Arabic numerals, interactive numerals introduce another way of using and thinking about numbers. Properly understanding interactive numerals is essential for all computer applications that involve numerical data entered by users, including finance, medicine, aviation and science

Preschool literacy and reading performance in primary school

A literacia pré-escolar tem recebido uma crescente atenção. Neste estudo, participaram 70 crianças que iniciaram o 1.º ano de escolaridade no ano letivo 2009/10 e que, na educação pré-escolar, frequentaram três instituições com abordagens diferenciadas de leitura e de escrita. O estudo inclui quatro medidas repetidas no tempo nas áreas da fonologia, reconhecimento de letras, palavras e velocidade de leitura. Os resultados sugerem que a abordagem específica à leitura na educação pré-escolar condiciona o desempenho da leitura na instrução primária. Contudo, essa influência parece ser atenuada com o tempo. Por outro lado, verificou-se que sujeitos que receberam instrução direta de leitura em idade pré-escolar (mas não treino fonológico) obtêm resultados significativamente superiores em tarefas fonológicas aos de sujeitos que receberam treino fonológico prolongado (mas não de leitura).The debate regarding kindergarten literacy has received increasing attention and social visibility. In this study, participants are 70 children who attended first grade in 2009/2010. Participants attended three kindergartens with unique approaches to reading. A four wave repeated measure design was conducted to investigate the growth of the children in phonological awareness, letter recognition, word recognition, and reading speed. Results suggest that the approach towards reading and writing in kindergarten affects children's performance in grades 1 and 2 of elementary school. This influence, however, seems to fade over time. Moreover, results show that children who received formal reading instruction in kindergarten, perform significantly better in phonological tasks than children who received direct and extended phonological instruction.(undefined)info:eu-repo/semantics/publishedVersio
