Instructional communication is a process of transferring some messages (knowledge) from teacher to students. Materials will be understood when the materials conveyed are understood by students as what teacher really addresses. Instruction is closely related to communication as it is an attempt to nurture students learning. Instruction will smoothly run when communication process also runs well. In contrast, instruction will not run well when communication halts. When a teacher delivers his/her material to students, indirectly the communication occurs. When communication runs well, students soon give feedback (e.g. their writing performance or their satisfaction).
