A review of application of 3D hologram in education: A meta-analysis

The evolvement of technology has made tremendous contribution in the field of education. Generally, technology of three-dimensional hologram (3DH) involve spatial displays which detaches the display technology from the user and integrate it into the real environment. This type of technology had been introduced with proven advantages for several decades especially in the field of digital art and medicine but yet to be explored in education field. This study takes a meta-analysis approach to review the studies and provide a comprehensive analysis of ten studies from the year 2005 to 2015. These previous papers were analysed qualitatively and summarized according to the uses of 3DH as a visualization tools for teaching in various fields of education. This study shows 3DH is an effective teaching tool in attracting students' attention and enhance their understanding. This was because 3DH can dismantle a complex topic to a simpler form which improves students' comprehension. This study will provide valuable insight for educators to integrate 3DH technology as a replacement for the traditional learning method currently in use.
