The purpose of this study is to compare the achievement of students' activeness and learning outcomes in the teaching-learning process using Adobe Flash CS6 interactive media-based multimedia compared to conventional learning in Accounting with the material on journal adjustment for Vocational Middle School students. The research method used was the quasi-experiment method with the pretest-posttest control group design. The population of this research is first year vocational middle school students. Data sampling was conducted using the purposive sampling technique for the experiment class and the controller class. The data collecting technique used was observation, test, and documentation. The analysis technique used to test the result of this research was the independent sample t-test. The result of this research showed that there is a difference in the activeness of the students’ learning in the learning process using the Adobe Flash CS6 interactive media-based multimedia compared to conventional learning. The result of the t-test with the significance level of 5% showed a significant difference of 12,889 ≥ 1,994 between the experiment class and the controller class. The average rate of students' activeness from the result of the observation instrument was 51.42 for the experiment class and a lower result for the controlled class with 40.30. Furthermore, it is also proven that there is a difference in the learning outcome of learning using the Adobe Flash CS6 interactive media-based multimedia compared to conventional learning. From the result of the t-test, there was a significant difference of 14,254 ≥ 1,994. The average rate of students' learning outcome of the experiment class was 89.72, whereas the controlled room was 71.25. The gain score of the experiment class was within the high category while the controlled class was within the moderate category. Keywords: instructional media, Adobe Flash CS6, students’ learning activeness, students’ learning outcome. 1 Introduction Teachers as educators are required to be able to deliver the materials optimally and liven up the teaching-learning process. The teaching-learning process is a two-way process that cannot be separated between the teacher and the students. In this process, the educator delivers material that has been appropriated to the goal of the study with the means of educating the students. The best teacher is those who provide education that is understandable, easy, interesting, implements proper class management, and builds a strong relationship with their students [1].
