DATA – A safe and respectful approach for assisting students in VR

Child protection is a serious issue in today’s society. There are laws, policies and procedures to ensure the welfare of children and young people. Schools are required to provide a protective and caring environment where student safety and well-being are paramount. In Australia, working with children checks are required by law before people can work or volunteer in settings with children and young people. School education systems have clear guidelines for teachers on what constitutes acceptable practice and respectful behaviour towards students.

When you first use VR headsets and hand controllers they can be awkward to put on, take off and adjust. Students often ask teachers, researchers or other students to help them with this. Even with a virtual guardian or chaperone system which indicates safe boundaries, people can move around in VR and come too close to objects putting them at potential risk. It is sometimes necessarily to help students to re-orientate back to a safe space in the real world so that they can avoid hitting objects (as part of the VR School project we always have a ‘spotter’ who looks out for the safety of students). When using a headset a person is either in darkness while they are waiting for an application to load or in the virtual world; basically, they cannot see what is going on outside or who is near them. It can be a bit of a shock to be in a virtual world and have someone in the real world start talking to you or putting a hand on your shoulder! Importantly, we need to be particularly mindful of students who have special needs, life circumstances or cultural norms which have made them touch-adverse.

So how can teachers, researchers and student-helpers interact with a person in VR in a safe and respectful way?

As part of the VR School project we have developed the DATA protocol. This involves involves 3 actions outlined in this poster:

Training teachers, researchers and student-helpers in the DATA method of interaction will go a long way in ensuring VR experiences are safe and respectful for all involved

Questions for teachers to ask about computer games for learning

Globally, an estimated 1.4 billion people play computer games, with growth in popularity driven by mobile device uptake, app proliferation and social media engagement. In Australia, around 98% of households with children have video games, 90% of gamer parents play games with their children, and 35% of children have played games as part of the school curriculum.

There are two types of games used for learning. The first type are ‘serious games’. These are designed to harness the popularity of recreational gaming for specific educative or training purposes. The second type are commercial off-the-shelf (COTS) games.  These are recreational games that can be adopted/adapted for learning (the original versions of Minecraft are an example of this).

There is growing evidence that serious and COTS games can be highly motivating and produce positive effects on learning.

However, teachers do face decisions about the selection of games, their alignment to curriculum, suitability for learners, and their place in the pedagogical repertoire. In this networked world, there are also ethical and technical issues to resolve.

Serious Games Framework Poster

To assist teachers in choosing and using computer games effectively in classrooms, we have produced a paper on evidence related to this and we have developed a practical framework in poster form (above). This framework is designed to scaffold teachers to ask critical questions about gaming for learning. We hope that it can be used to increase the effective integration of games into classrooms to benefit both teachers and learners.

Information for parents, carers and students on the VR School project

To take part in the VR School project, parents, carers and their child must give their written permission (this is also called consent). Details on the project can be found in the video Information Statement and the written Information Statement. A Parent/Carer and Student Consent (permission) Form is also available. The consent form has a section for students to give their agreement to take part in the project. The Information Statement and Consent Form are also available online through the College’s Canvas learning system.

Setting up the Oculus Rift in the classroom

Today we set up the Oculus Rifts with their controller tracking system at Callaghan College (Wallsend Campus).  The three Rifts were set up in a small room attached to the main classroom. Chris (pictured below) took the lead in setting up the equipment with two Rifts set up with the trackers on desks, and the other having its trackers mounted on the wall. Chris is a Future Learning Coordinator at Callaghan College, a geography teacher and a co-researcher on the VR School project. Some students and staff tried out the equipment with great success.

VR School wins Callaghan College a Top Innovative Schools award

Callaghan College  has been named by The Educator magazine as one of the ‘Top 40 innovative schools in Australia’ for the VR School project. VR School is a partnership between the College and the University of Newcastle’s Digital Identity, Curation and Education (DICE) research network. The project uses the Oculus Rift to provide immersive learning experiences for Year 9 students in science and is producing world-first ethical, health and safety, and pedagogical resources for the use of immersive virtual reality in real classrooms. Impacts on student learning are also being evaluated.

Callaghan College has previously been recognised as a top innovative school by The Educator for its whole of College professional learning in 21st Century pedagogy (2015), and the design, development and implementation of a National first program in Certificate III Aviation – Remote Drone Pilot (Line of Sight) (2016).

Teachers talking VR safety

Teachers have an important duty of care towards their students. To support this, we developed a script for teachers to use in their classrooms to teach students about staying safe in immersive VR.

The script is part of a suite of health and safety resources we developed as part of the VR School Project. It covers things such using hair nets for hygiene, what students should do if they feel cybersick, not staying in immersive VR for too long, and looking out for each other, particular when using VR in ‘moving around mode’ with the controllers.

The script reinforces and elaborates on the advice given on the ‘Be VR Aware’ classroom posters.  It can be found in Resources.

‘Be VR Aware’ classroom posters

Everyone needs reminding to stay safe, so as part of the project we decided to design the ‘Be VR Aware’ classroom posters.

We produced two versions of the poster, one of which has been designed according to accessibility principles. Both versions can be found in Resources.

VR School Project Classroom Safety Poster_Accessible

Emojis representing specific safety aspects, combined with simple text, allow students with lower literacy levels to understand the safety messages. For learners with good literacy, the use of visual representation with text allows for a dual coding of the information during cognition, helping the learner to better recall the message.

The accessible version has the black background. It reflects advice from Vision Australia and the UK Government. The text used in the posters is predominately Verdana, a Sans Serif font, which is ideal for readability.

 

We used plain English, avoiding colloquialisms and complicated phrasing. The text colour is white for maximum contrast against the black background. To test this we used the colour contrast check available at snook.ca. The background is simple and black to provide a contrast with the white text. Complicated backgrounds are not recommended for accessibility purposes. Black was used as it allows the simple colours of the emojis to stand out. It is also recommended for use for people who are colour blind. The tool available at vischeck.com was used to test this.

Please let us know what you think of the posters or if you use them.

Keeping students safe and well in VR

Have you ever been cybersick? It’s just like being seasick or car sick. It can range from feeling mildly ill to being highly nauseated. Not everyone gets cybersick but many people do and it’s just one aspect of health and safety that needs consideration when using immersive VR in classrooms.

A lot of research is going on to determine who is most susceptible to cybersickness, and under what conditions. Cybersickness can come on even after a very short period of exposure, particularly in highly immersive VR where a person can have intense feelings of ‘being there’ and ‘move’ in the environment through navigation or interaction.

At this stage, not much is known about the health effects of highly immersive VR, especially on children and young people. In light of this, the VR School Research Team are committed to conducting the project with caution and to the highest ethical and safety standards. Before using highly immersive VR, teachers should read the safety and regulatory guidelines provided by manufacturers on their websites. These guidelines recommend minimum age of use requirements and outline potential adverse reactions including, but not limited to, photo sensitivity and a range of physical and psychological impacts. It should also be noted that current commercial head mounted displays (headsets) are not designed for the size of children’s heads in terms of fit and lens distance for correct alignment with the eyes of the user.

To identify potential adverse reactions, we reviewed the scientific literature and the safety and regulatory guidelines produced by manufacturers. From these, the team designed a VR School Health and Safety Survey, that can be found in Resources. We used this to screen for potential adverse reactions and minimise risk of harm to students and disruption to learning. For example, a student with moderate or severe cybersickness would have a recovery time that impacted not only their learning during the VR lesson, but into the school day.

Disruption to learning caused by exposure to VR is simply not acceptable, nor is the potential for more serious health impacts on student health.

The screening survey we developed was sent home to parents and carers with an information sheet on the project so that they could discuss health and safety with their child, and ensure informed consent.

As the field of immersive VR for learning matures, we welcome the open sharing of information from teachers, students and researchers alike on how to screen for and minimise health risks for students. This is an important new area that requires the formalisation of guidelines, the development of practical tools, and the documentation of case studies so that we can all use VR safely in classrooms.

Ever wonder what happens when immersive VR is used in real classrooms?

How can the real environment of the classroom interact and intersect with the virtual environment for deep learning and fun?

Virtual reality is becoming ubiquitous and affordable with people asking how it might be used to offer students, of all ages, wondrous learning experiences. When I scroll through twitter feed, I see all kinds of educational technology (ed tech) articles on virtual and augmented technologies, usually featuring glossy stock photos of children and young people sporting the wide-mouth VR gape, a kind of visual short-hand for just how amazing an immersive VR experience can be. Most of the articles that accompany these images are about how the special affordances of VR (its properties or possibilities for action) can be used for learning – for example, virtual field trips to amazing places on and beyond the planet and the ability to manipulate the scale of virtual objects from the smallest (exploring a single human cell that appears as large as person) to the largest (zooming in and out of archaeological sites from an aerial view to a single in-situ artefact).

While there is imaginative thought in ed tech, evangelist-style articles, there is also a surprising lack of evidence on what actually happens when immersive technologies are introduced into real live schools.

There is some research from the field of computer science and health on lab-based or clinical experimentation using immersive VR with children but this research often has small numbers of participants and can be limited in its implications to everyday ‘natural’ settings. Classrooms are dynamic natural settings where learning, in all its complexity, is influenced by a range of factors from the individual differences of students and their socio-cultural and geographic backgrounds, peer interaction, mandated curriculum and assessment options, and the pedagogy or the instructional choices teachers make every time they plan a lesson or step into a classroom.

So what happens when you provide students and teachers with the opportunity to use immersive virtual reality, in this case access to Oculus Rift, for learning?

How can the curriculum be tailored to use immersive virtual reality for deep learning and how can we assess if VR actually enhances learning?

What are the opportunities and challenges of using the latest VR technology in low-income school communities?

How do students and teachers experience immersive VR in their classrooms?

Importantly, given the developmental stages of learners, how can we use this type of technology safely and ethically in schools?

The purpose of the VR School project is to create a robust, evidence-based dialogue on these questions based on the data we collect during our collaborative research with the the urban Callaghan College school community and rural Dungog High School. We intend to openly and ethically share our insights and the resources we produce as part of the project so that the use of immersive VR in classrooms is thoughtful and powerful for learning. We welcome dialogue from students, teachers, policy-makers, researchers and developers on using immersive technology in schools and other educational settings.
