This study aims to know the implementation of blended learning models using liveboard to affective aspects in modern physics course. The method used in this study was a pre-experimental design (nondesign) with the design of the study one group pretest-posttest design. The population in the study were all students of physics education UHAMKA. The sample used purposive sampling entire fourth-semester students of physics education as many as 22 people. To view the affective aspects of the modern physics course as evidenced by calculating the index gain. The results of N-gain in the course of modern physics based on a questionnaire obtained a practical value of 0.59 with a percentage of 62.82 percent of student's possible value. Results of simple linear regression demonstrate the importance of Y = 45.578 + 0,422X. Based on the cost can be seen that the learning model of blended learning influences the affective aspects of students. In the hypothesis test, used t-test obtained in modern physics tcount = 1,818 with ttable = 1.717 at α = 0.05, so H0 was rejected, which states that there was a significant influence on learning using blended models based learning liveaboard terms of affective aspects.
