Android programming learning assistance system (APLAS) has been proposed and implemented as a self-learning platform of Android programming to help learners. To cover wide topics, APLAS offers various assignments with rich materials through four stages. Guide documents take important roles to help novice students completing the assignments by giving the details of the parameters and commands required in the source codes. However, students will have to write codes without them for practical programming. In this paper, we investigate learning outcomes of APLAS by asking 54 third-year undergraduate students in Makassar State University, Indonesia, to solve the rectangular prism assignment in the Interactive Application stage without giving guide documents. These students had previously solved other assignments using guide documents. The results show that only one student failed the assignment, which confirms the effectiveness of APLAS learning in this assignment.
