Can an Educational Design Research Model be Applied to an Entire Curriculum?

Dentistry is a hands-on profession. Dental, dental hygiene and therapy students will attest to the hours spent in laboratories, pre-clinical classes and dental clinics honing the psychomotor skills necessary to safely and effectively deliver care to their patients. In addition to exceptional psychomotor skills and a broad foundation of theoretical knowledge, interpersonal and reflective skills are also needed in the education of a skilled clinician. For centuries, the required learning activities have occurred in lecture theatres, seminar rooms and clinics with students and their teachers sharing the same physical space. The rapid disintegration of face-to-face teaching in early 2020 resulting from the CoVID-19 pandemic and associated social distancing mandates has been particularly jarring for a profession whose very essence lies within another’s personal space.

However, it has given those of us working in dental education the opportunity to reflect on how we might reframe dental education in the future by integrating the best that technology offers to support our students in acquiring the attributes necessary to become a competent clinical professional (Machado, Bonan, Perez, & Martelli, 2020).

Late last year, I was afforded the opportunity to lead a curriculum review of the two entry-to-practice degrees – the Bachelor of Oral Health (BOH) and the Doctor of Dental Surgery (DDS) – at the Melbourne Dental School. It has been over 10 years since the current curricula were designed and during that time, not only has technology advanced, but student expectations of their learning environment have also changed. Dental students are expecting that their time at dental school will include online learning, and they see this as helping them transition from a preclinical to a clinical environment (Inquimbert, Tramini, Romieu, & Giraudeau, 2019).

Much of the online learning the Melbourne Dental School students experience was adopted in acute response to the pandemic during 2020, and was not preceded with thoughtful decision-making. To maintain the continuity of dental education, educators scrambled to transition their teaching and learning activities from the traditional physical learning environment to the generally poorly understood, and to many mysterious, virtual environment. As I have been exploring the literature around curriculum, online learning and educational design research, I have been trying to determine how I can piece all these together.

From a pedagogical perspective, as a school we know what direction we should be moving in.  We need to reframe how we engage in theoretical dental education to leverage the best from both online and face-to-face class time with a blended learning approach; active collaborative learning, authentic problem solving and opportunities for self-reflection.

The process of designing a new curriculum to meet accreditation standards of a health professions degree, whilst transitioning from a traditional face-to-face, lecture based approach to a blended, collaborative approach is a complex problem (or series of complex problems…) that requires practical solutions. When I first read about the Education Design Research framework (S. McKenney & Reeves, 2020) it seemed appropriate for smaller education design research questions…but to borrow from Kylie Minogue, I can’t get it out of my head.

Education design research involves the development of solutions to practical and complex problems. The theoretical knowledge developed during this iterative process can then inform the work of others (S. McKenney & Reeves, 2020). The three main phases of the model for conducting educational design research (analysis, design and evaluation) were based on models for instructional design and curriculum development (S. E. McKenney & Reeves, 2019).

The following video has a description of educational design research.

It therefore aligns with the model of curriculum design that I am employing (figure below) (Thomas, Kern, Hughes, & Chen, 2016). The ‘General Needs Assessment’ and ‘Learner Needs Assessment’ steps are ‘Analysis’, ‘Goals and Objectives’ and ‘Educational Strategies’ are ‘Design’ and the ‘Implementation’ and ‘Evaluation’ steps form the ‘Evaluation’ phase of the model for conducting design research in education (above).

However I have questions I need to answer before moving forward. Do I apply an education design research approach to designing a whole 3 (BOH) or 4-year (DDS) curriculum? Or should I be approaching this as multiple smaller research projects? Or should I be doing both? It would seem from the literature that the different steps in the curriculum design process could serve as individual education design research projects, but that they are likely to overlap (Kopcha, Schmidt, & McKenney, 2015). So with my head spinning with questions, possibilities and a little bit of fear I will end with Kylie again…

(Obviously a gif of Kylie’s ‘Spinning Around’ as opposed to just Kylie spinning around was what I was after here…however I could not find one. Also, I doubt it would be considered appropriate to have that much skin on display on a reflective blog on higher education!)

So THAT’S what cognitive load theory is…

For something that brings a solid evidence-base to help inform the design of learning materials for students, I am surprised it has taken me a good 14 – 15 years to get a handle on understanding what cognitive load theory is, and how I might be able to use it to improve student learning. However perhaps through my combined experience of both teaching in higher education and presenting research has enabled me to build an understanding of this theory without knowing it was a theory!

This became evident over the last week as I prepared two different presentations. Early last week I needed to prepare a presentation to share my experience at ‘The Flipped Classroom in MDHS: Recent Experiences and Directions’, a Faculty of Medicine Dentistry and Health Sciences Learning & Teaching event. Towards the end of that week, I started working on a presentation for the EDUC90970 Facilitating Online Learning subject on Cognitive Load Theory.

In the ‘Flipped Classroom’ presentation I needed to share with my audience the basic premise of this model, results from a pilot study I carried out in 2020 as well as tips and insights from my experience. All in a 7-minute pre-recorded video. To do this, I started by eliminating any information that was not essential to telling the story. I employed simple transitions in PowerPoint to help highlight the important material, I told much of the story by narrating to images, with no onscreen text, presenting the speech and graphics simultaneously. Simple definitions were added to the start of the presentation and I tried to limit the use of on-screen text, presenting information in spoken form instead. When student quotes were used, I left these onscreen for viewers to read without any accompanying speech. These are strategies I have developed over years of experience in presenting information to both students and colleagues as well as sitting in many presentations as a student or researcher.

I then got working on the cognitive load theory presentation. Cognitive load theory is based on two basic concepts. Firstly, that as humans we have a limited working memory load, but an unlimited long-term memory (Kirschner, 2002). This is laid out in this simple video:

Secondly, our working memory load is affected by three different types of load related to the intrinsic nature of the task (intrinsic load), the way in which tasks are presented (extraneous load), and the amount of cognitive resources needed to transfer knowledge into our long-term memory (germane load) (van Merriënboer Jeroen & Ayres, 2005). These different loads are explained well in this video:

Cognitive load theory has been adapted to online learning with the cognitive theory of multimedia learning which incorporates the principle that we have two separate channels for processing auditory/ verbal information and visual/pictorial information (Mayer, 2019).

Flow chart representing the cognitive theory of multimedia learning (Mayer, 2019).

While reading about cognitive load theory, I came across a narrative review of research on online learning by Richard Mayer (Mayer, 2019). This paper largely discusses the research findings regarding instructional methods that can be employed to reduce extraneous cognitive load when designing learning activities for an online space. I was interested (and relieved!) to find that many of these methods I have stumbled across through many years of trial and error, and had recently employed in the presentation I had finished only days before.

Reflecting on my experience exploring cognitive load theory, and the cognitive theory of multimedia learning over the last week, I feel that I will now be far more purposeful in my design of online learning materials and activities, confident that I will be making choices based in cognitive science rather than just hunch.

You can watch my presentation for ‘The Flipped Classroom in MDHS: Recent Experiences and Directions’. It is not perfectly employing the cognitive theory of multimedia learning, but it does incorporate some of the instructional methods for reducing extraneous processing during learning outlined in Mayer (2019).
