Every year, there are students from the Department of Early Childhood Education (ECE) who need to do questionnaires for their research reports and need assistance from the nurseries, and this year is no exception. In addition to the questionnaires, in early June, some students called to ask if they could be assisted in their research for a special topic course. The theme of the study is the correlation between preschoolers' visuospatial working memory and different forms of flipping games. The study aims to understand the differences in preschoolers' performance and strategies in different forms of flipping games (traditional flipping games and electronic flipping games), as well as the differences in their visuospatial working memory.
