Introduction 

In early 2020, the US faced a nation-wide shutdown of learning institutions due to the COVID-19 global pandemic. As a result, many colleges, universities, elementary schools, and secondary schools (K-18 schools) quickly and gracelessly shifted to finishing courses online, utilizing tools that gave both synchronous and asynchronous opportunities. While most instructors and researchers are likely to agree that the elements that make up quality instruction will be true regardless of the environment, the strategies that are required to fulfill these requirements will not be the same in a virtual environment as it would be in an in-person environment. In other words, while principles of best practice exist in all learning environments, pedagogical approaches must be adjusted in ensure  to make it work because pedagogical approaches that work well in one learning environment very rarely transitionwell into another learning environments.
This paper will introduce a framework that builds upon the work of Graham et al. (2000). This framework is a more complete guide to course development and delivery that works regardless of the teaching mode.

Literature Review

Most instructors have good intentions when creating online courses, however the strategies that should be utilized to make them effective are not easy to identify \cite{duffy2000}. One such concern is that utilizing some strategies that work during in-person synchronous instruction don’t translate well to the online environment (such as peer-to-peer interaction) and can cause both the instructor and students to spend too much time managing it, thus adding additional stressors to the course \cite{duffy2000}. Before introducing our framework, it is important to highlight prior work in the field of pedagogy in varying classroom environments. In this section, we will define what we mean by classroom environments, review the role of pedagogy in existing frameworks, describe how this pedagogy plays out between in-person and distance education classroom environments, and explain why a new framework is needed.

And we are going to stick to those definitions. We are not being arbitrary, but we are helping you, the reader, to make sense of these terms.

Classroom Environments

For our paper, we will refer to teaching mode as the scope that spans in-person, correspondence, and distance education environments as well as the hybrids that include various elements of each. As has already been shown in \citet{chickering1987seven} as well as \citet{duffy2000}, the principles that make up good education practices are the same, regardless of the classroom environment. Rather it is the instructor’s approach to pedagogy that makes each of these principles effective in each classroom environment \cite{Bernard_2004}. Therefore, we assert that the fundamental principles of good instruction do not change when modes change; however, they do require a different pedagogical approach to in order to achieve them in each environment.
