This paper analysed how three teacher-researchers of Singapore's elementary school used online space extensively in Grade 2-Grade 4 classrooms. Such online space, made possible by free and readily available web 2.0 and open source applications, was meant to complement the physical learning space as such space can allow learning activities, which were otherwise not possible in the typical classroom setting, to be carried out. The results revealed that students have positive learning experience but the learning impact was small. Despite such unfaltering results, the teacher-researchers were not daunted due to their strong conviction that technology is vital in their students' learning. (Contains 6 figures and 12 tables.)
