This study explores how blended learning can contribute to interior design students' learning outcomes, their engagement with non-studio courses and affect their learning achievements. Within the framework of the study, a blended learning experience was carried out in "IAED 342 Building Performance" module at Bilkent University, Turkey. A total of 120 interior architecture students were surveyed about their experiences on five fields of instruction: (1) course design, learning material and electronic course environment; (2) interaction between students and instructor; (3) interaction with peers; (4) individual learning process; and (5) course outcomes. Frequency distributions, chi-square factor and regression analyses were calculated. Four blended learning factors were developed and their contribution to learning outcomes was analysed. The results showed that teaching both online and face-to-face can create an effective learning environment for non-studio classes, while contributing to a considerable value for the interior design education in terms of teaching process.
