Twenty-one 5th graders participated in this study forty minutes per week, lasting for sixteen weeks. They were required to co-create English picture books of Pinghu through thematic task-based activities. Research data required for the study were collected through the pre-/post-tests of vocabulary and cultural knowledge, a participants＇ feedback questionnaire as well as semi-structured interviews. The results of this study showed that after experimental instruction, EFL 5th graders significantly improved their recognition of the connection between English word sounds and word meanings, word meanings and word forms, word forms and word meanings, as well as spellings. Moreover, their local cultural knowledge was improved significantly as well. Furthermore, based upon the 5th graders＇ responses to questionnaire and semi-structure interview, most of them developed a very positive attitude towards the activities of co-creating local picture books and their interest, self-confidence in English writing, and English learning behavior. Based on the findings, some suggestions were offered for the pedagogical applications and future studies.展开更多

This paper documents some of the constraints in utilising larger proportions of manufactured sands in concrete pavements. These constraints are mainly caused by the current level of knowledge regarding the impact of manufactured sands on skid and abrasion resistance of concrete pavements. This paper presents a brief review of literature on this subject in the USA, France and UK. It also briefly documents work recently carried out in Australia by CCAA （Cement Concrete and Aggregates Australia）, referring to the skid and abrasion resistance of concrete pavements using manufactured sands. The paper concludes that there is no relationship between the free silica content and the skid resistance. With regard to the abrasion resistance, it is rather the curing conditions and the compressive strength that are more important in achieving good results.展开更多
