The document summarizes a research plan that aims to study the effectiveness of using English weblog writing to promote writing skills among primary school students in Hong Kong. The research questions examine whether weblog writing can improve English writing abilities and whether there is a relationship between writing frequency and skills. Sixty students with similar English levels will be selected and divided into experiment groups that write blogs or diaries daily and a control group. Pre- and post-tests will analyze score changes to determine if blogging significantly impacts writing development.
