The researcher found a problem in designing an instruction often ignore the message design because it is focused on syntax andrnlearning systems, including the design of innovative learning such as e-learning, online learning, blended learning and mobile learning.rnBased on these problems, the researcher develops a model of design message in blended learning. The goal is to help the educators to facilitaternlearners to interpret and construct teaching materials. The development used ADDIE models. Qualitative and quantitative data wererncollected through observation, interviews, questionnaires, and tests in order to produce a model of message design. The validity of thisrnproducts was tested by expert and the practicality and effectivity testing by the user in the course of Theory of Learning and instruction.rnThe result of this development consists of (1) the book of model design messages in blended learning, and (2) the learning tool that consistsrnof teaching materials, media presentations, e-learning, syllabus, SAP that is valid, practical and effective. The Book model can be used byrndesigners of instruction, learning consultant, and lecturer/educator in helping learners to interpret and construct learning message so thatrnthey have an ability to generalize the learning and become independent learners.
