Virtual reality, augmented reality and surgical training
Memory and visualization
Many pieces of research have discovered that the use of three-dimensional objects can improve visual- spatial retention compared to two-dimensional ones. A research study was carried out to investigate whether the use of three-dimensional blocks helps improve visual-spatial retention, by comparing their scores on a Purdue Visualization of Rotation test before and after interacting with the three- dimensional blocks. It also suggests that using these three-dimensional objects can help with mental rotation and potentially science-based skills (Bernhardt-Barry, Datta, LeBow, 2018). Moreover, when using three-dimensional visualization, it allows users to inspect and examine from different perspectives and angles, allowing more interactions with the object compared to two-dimensional (Brassea, 2020). Due to varied interactions with the three-dimensional objects, our memory of the visual aspect of our senses improves, suggesting that it would be easier for us to mentally recreate the image (Jobes, 2020).
Method
To recreate a learning environment, I set up an experiment that tests participants' memory on systems of the human body with the help of AR models and images. The study population consists of Year 12 students within the same age group; 64 students were selected to be part of the experiment. They were assigned into two groups, where one group studies AR, while the other studies images. Firstly, the participants needed to carry out a digit span test. It is to determine the working memory, a cognitive skill that determines the ability to store, manage and manipulate information and it is to ensure the working memory was not a variable that affected the results of the experiment. Then, students sat a recall test before and after the studying period, and the percentage increase in the scores are compared. The research carried out by Andersen, Bansal, Gallagher, O'Brien, Roman, Satava and Seymour (2002) demonstrated that using VR to train can improve

the performance of surgeon trainees, where the length of the procedure was shorter and fewer errors were made throughout the process (Andersen et al., 2002). The hypothesis generated for this experiment is that participants who studied using AR will be able to strengthen their memory on the study resources better than participants studying the images.
Objective
The objective of this experiment is to examine the effectiveness of augmented reality and images on learner's memory skills.
Methodology
1. Complete the working memory test (digit span test). 2. Complete the baseline pre-test. 3. Study the images/AR models for 1 minute. 4. Complete the post-test.
