The effectiveness of Gesture-Based Learning System (GBLS) has been reported in some recent studies. However, not many of those studies have investigated on how GBLS mode influences the learning outcomes. The aim of this study therefore focuses on investigating how GBLS mode impacts the learning outcomes. The findings of this study revealed that GBLS's features positively affect the students' intrinsic motivation. Consequently, the increase in the intrinsic motivation leads to improving the learning outcomes; this study also showed that GBLS's features indirectly influence the learning outcomes via intrinsic motivation. In other words, this study found that the GBLS's features (interactivity and multimodality) create an instructional learning environment that positively influences the students' intrinsic motivation. The increase of the students' positive intrinsic motivation led to enhancing the learning achievements of students.

Several studies and experiments have been conducted in recent years to examine the value and the advantage of using the Gesture-Based Learning System (GBLS).The investigation of the influence of the GBLS mode on the learning outcomes is still scarce. Most previous studies did not address more than one category of learning outcomes (cognitive, affective outcomes, etc.) at the same time when used to understand the impact of GBLS. Moreover, none of these studies considered the difference in students’ characteristics such as learning styles and spatial abilities. Therefore, a comprehensive empirical research on the impact of the GBLS mode on learning outcomes is needed. The purpose of this paper is to fill in the gap and to investigate the effectiveness of the GBLS mode on learning using Technology Mediated Learning (TML) models. This study revealed that the GBLS mode has greater positive impact on students’ learning outcomes (cognitive and affective outcomes) when compared with other two learning modes that are classified as Computer Simulation Software Learning (CSSL) mode and conventional learning mode. In addition, this study also found that the GBLS mode is capable of serving all students with different learning styles and spatial ability levels. The results of this study revealed that the GBLS mode outperformed the existing learning methods by providing a unique learning experience that considers the differences between students. The results have also shown that the Kinect user interface can create an interactive and an enjoyable learning experience.
