This study attempts to introduce the computer aided classroom teaching with English open educational resources (OER) on internet in the course of Signals and Systems. The expected responses are: (1) students will feel easy. to study from the combined materials of translated textbooks and English aided educational websites from internet; (2) students can be induced to surf on the OER for self-study; and (3) students can improve the English reading by studying English OER with teacher's explanation of vocabulary and sentences. These responses were examined by the questionnaire. The computer aided classrooms were equipped the teaching-broadcasting and learning-monitoring s0ystem in department of electronic engineering, Tung-Nan Institute of Technology (TNIT). This system can be controlled to broadcast the screen of the teacher-use-only computer to those of student-use PCs, and synchronously connected with a projector to display onto a large screen or a hand-writing board. The results showed the presentation of the OERs actually dives the students a good guide to learn. Generally, students agreed that the aided content of the OERs is helpful to learn this course. Further discussions present the factor analysis of the OER aided integrative teaching from the aspects of university to teachers, university to students, and teachers to students, to evaluate the benefits of the integrative teaching method. Therefore, this study suggests the concept of vocabulary spectrum from our previous studies to help teachers and students learn OER especially in the non-English native speaking nations (NENSN). The presentations of computer aided plots and movies in the OER websites and software are intuitively much helpful to conceptual understanding in English to improve technology level and elevate language ability. On the other hand, the students in NESN can understand the knowledge and cultures of NNESNs' from OER vice versus. The selection of the textbook was one of the dominant factors to the teaching quality before, is now more important in the OER aided teaching. The combinations and linkages of contents between the OER and the textbook will be the most important work of teaching, because the content of the OER could be summarized from many textbooks causes the necessities of the combinations and linkages.
