Previous arguments concerning the influence of technology onlearning have proposed that it is either the medium that influenceslearning or it is the instructional design applied to a particularmedium that enhances knowledge acquisition (Oark 1983; Kozma1991). Absent from both perspectives is the role of the teacher andhowheorshemustunderstandandmanagenotonlythetechnologyand the instructional materials used, but must also be cognizant ofother instructional components necessary for the effective use oftechnology. This paperreemphasizes the status of the teacher as thecentral decision-maker of technology use in language teaching, orin this instance, media-basedlisteningcomprehension. Previousresearch and recent results of a qualitative study on the" mismanagement"of listening comprehension technology support andreflect how a teacher's combined knowledge of students' preferencesand needs, sound pedagogical and theoretical strategies, andthe media and materials used can influence language learningthrough media-based activities.
