The Cognitive Theory of Multimedia Learning (CTML) offers insights on creating, organizing and presenting multimedia content in a way that can enhance the effectiveness of learners. While several studies have been conducted to verify these principles, not many have been done using content presented on low cost tablets. In this paper, we present our experimental study on the retention and understanding by children when learning content a) adheres to CTML and b) offered on low cost tablets. In our study we used Online Labs theory and videos and incorporated CTML principles into it. According to CTML principle it will maximize learning without causing cognitive overload. The study sample was 58 students from an English medium secondary education school from south India. The experiment involves a control and experiment group where the control group is tested on content which does not adhere to CTML and the experimental group is tested on content designed based on CTML. A pre-test is conducted to assess the level of pre-knowledge in the subject and a post-test is conducted to assess the retention and understanding by students. This suggests that tablet content incorporated with CTML principle can lead to a deeper understanding of the subject.
