If this is the same concept of which I am thinking, interactive Language Arts is the same content, but the manner in which it is taught is more student centered. Instead of the more traditional way of teaching language arts, driven by "what" is taught, a more interactive approach focuses on "how" it is taught. The premise behind this is that modern students are fundamentally different from a cognitive standpoint than their predecessors. Part of this is due to the proliferation of technology that envelops the modern student, allowing them to understand more information and have difficulty sorting it out and assessing it. In the end, I think that this is where the interactive nature of the discipline enters. The teacher in this setting teaches the the skills of critical thinking in a manner that is student centered, making the teacher more of a facilitator of understanding than the font of it. In the interactive setting, content is taught through the learner, where options and differentiated instruction is scaffolded so that students can feel more empowered and greater activity within their learning setting.
