   ABSTRACT
This study aims to examine the learnersí mental models of different media activities in actual media classroom activities by which knowledge was constructed. It aims to clarify the formation of the Thai learnersí mental models of different media related to their learning achievements using the topic of ĎPythagorasís theoremí in ninth-grade Mathematics as a case study. A qualitative approach was used to investigate the effects of using five media activities, especially as they facilitate learners in the construction of mental models for understanding the learning content. The sample group were 199 ninth-grade students; 5 classrooms of Nakorn Khon Kaen school, Khon Kaen Province, Thailand, in the first semester of the 1997 academic year. Each of the classrooms learned through one of the media activities (watching television, using computer, reading activity, writing activity, and teacherís lecture). The preconception questionnaires were administered in each class before they began learning. After finishing the media activities, 10 learners from each media activity classroom, 50 in total, were interviewed to ascertain their mental models. The findings revealed the learnersí mental models, which they constructed while learning through using each media activity. Specifically, they revealed how media capabilities and the instructional designs that employ them interact with the learners and the task characteristics to influence the formation of the learnersí mental models and their learning achievement.
