The purpose of the study was to find problems of the current classroom and expectations in the future classroom perceived by teachers in secondary education. In order to achieve the purpose, various prior studies on classroom environments and learning spaces have been reviewed, cases of classroom of futures were explored, and a survey was administered to 277 teachers. The results collected were analyzed by the content analysis method via Nvivo 8.0. Based on the analysis of the results, the followings were concluded. First, it was found that the problems teachers perceived most were lack of multimedia and their maintenance, improper students desks and chairs, blackboard and chalk, lack of student's lockers, small classroom space, and no air conditioning system. Secondly, teachers expected that the future classroom would have better and more multimedia, electronic board, new desks and chairs, student computers, subject matter classroom, better cleaning systems, and better air conditioning. Thirdly, comparing the problems and the expectations, it was found that the problems perceived by teachers and their expectations for the future classroom were closely related to each other. In addition, multimedia was perceived most as a problem and expected to be improved most in the future, along with the desks and chairs, and student computers. Based on the these results, it was assumed that we need to build the future classroom not by focusing on integration of new technology into classroom, but by considering users's needs and expectations. In order to design an effective classroom space, we need to consider first needs and expectations of the teachers who live there, then search technological media to fulfill the needs and expectations.
