Large LCD screen size is beneficial to many applications, especially those expanding several (screen) pages during operations such as spreadsheet or those requiring zoom-out, zoom-in, transition and rotation operations such as 3D Studio Max or Maya. For spreadsheet and 3D animation applications there exists a dependency between learning performance and physical screen size. However, few researches have touched this topic. Therefore, this study extends the SEM-CPU methodology to explore the learning performance of using Microsoft Excel and 3D Studio Max on 15-inch and 22-inch LCD displays. The subjects of this study consist of 67 undergraduates divided into A group 34 students and B group 33 students. All of them have been using Microsoft Excel for at least 3 years but A group students have never learned 3D Studio Max before and B group students have just finished introductary 3D animation course using 3D Studio Max. Experiments of two groups using MS Excel and 3D Studio Max were carried out in both 15-inch and 22-inch LCD displays. Results showed that (a) in self-comparison, the performance of using 22-inch display was significantly better than that of 15-inch display in Microsoft Excel for both groups; (b) in self-comparison, the performance using 22-inch display was significantly better than that of 15-inch display in 3D Studio Max for B group, but not for A group; (c) in group-to-group comparison, the performance of A group to B group using 15-inch display on Microsoft Excel was significant, but not significant for 22-inch display. (d) in group-to-group comparison, the performance of B group to A group using 22-inch display on 3D Studio Max was significant, but not significant for 15-inch display. From the results, this study showed the LCD display size played an important role on learning performance of Microsoft Excel and 3D Studio Max. To measure the pleasure, performance, interactivity, and satisfaction of students participating in the experiments, a 5-point Likert scale questionnaire were given to all students. The results showed that 22-inch display offered better pleasure, performance, interactivity, and satisfaction, especially pleasure and satisfaction, than 15-inch display regardless of Microsoft Excel or 3D Studio Max,. The findings of this study offer an important reference for researchers, teachers, or companies who are interested in studying the relationship between LCD screen size and learning performance.
