Portraying Social Constructs that Influence Health in Patient Cases

by Jewlyus Grigsby PharmD, PGY1 Community Pharmacy Practice Resident, University of Mississippi School of Pharmacy

One of the most common ways health profession programs assess students’ knowledge is through patient cases intended to mirror real-life practice scenarios. These cases are meant to place students in a “what would you do?” simulation and facilitate the development of their critical thinking and clinical skills. These cases are used during in-class discussions, on exams, in clinical skills competitions, in interviews, and for professional development. When designing these cases, faculty consider a variety of factors such as the severity of the patient’s symptoms, lab values, comorbidities, allergies and intolerances, and even family history. One set of factors that must be carefully considered when creating a case is the patient’s race, ethnicity, nationality, and socioeconomic status. These factors are social constructs, and therefore influence perception, decision making, and (all too often) health outcomes. In August 2021, the American Medical Association published updated guidelines about how to report race and ethnicity in the medical literature. These guidelines state that the words and terms used must be, “accurate, clear, and precise and must reflect fairness, equity, and consistency.”¹ Furthermore it also provides guidance on how to address sex and gender, sexual orientation, age, and socioeconomic status in research reports, review articles, and case reports. The goal of these guidelines is to reduce unintentional bias within the medical and scientific literature. However, despite now having a guideline instructing health care researchers and educators on how best to include these social constructs, how should this be done in the classroom setting and during experiential courses?

Ensuring the appropriate portrayal of diversity in patient cases should start with a careful reflection on the objectives of the lecture or topic being taught. This is especially important because test questions are often developed from the learning objectives. When writing learning objectives, one must ask what participants should be able to do as a result of the lecture, what the audience needs to know, and communicate the take-home message. By including objectives that relate to the social determinants of health, diversity can be introduced into the patient cases, and assist students in practicing disease state management with patients from diverse backgrounds. Here are three examples of how to structure objectives that include some of these social factors:

1. Create a treatment plan for patients within the confines of the state’s Medicaid medication formulary.
2. Design a medication regimen that accounts for and is consistent with a patient’s religious beliefs and practices.
3. Compare and contrast the prevalence of medication allergies and intolerances present in specific racial and ethnic groups.

These objectives challenge students to analyze a patient’s financial status, religious beliefs, and race/ethnicity in the context of the treatment regimen and medication characteristics.

After establishing the objectives for a presentation and determining whether specific social factors should be incorporated, the next step is to design the cases that will be used during the in-class activities and on exams. The cases should highlight the medical conditions under consideration but also highlight how political, economic, and social factors contribute to the patient’s o vernal health outcomes. It is also important to ensure the case does not reinforce biases and avoids stereotypes. This can be challenging because there is a fine line between something that might be more common in a particular population and a stereotypical patient presentation. For example, psoriasis is more common in Caucasian patients and diabetes is more common in African Americans. However, not all diabetes-related cases should be about an African American patient, and not all psoriasis cases should feature a Northern European! These diseases occur in people of all racial and ethnic backgrounds, but there may be some differences in presentation, clinical features, and severity that can be explored by featuring patients from various backgrounds.

One group, a non-profit organization, produces cases for courses in medical schools in the United States. They design their cases using an approach called “structural competency” defined as: 

the trained ability to discern how a host of issues defined clinically as symptoms, attitudes, or diseases also represent the downstream implications of a number of upstream decisions about such matters as health care and food delivery systems, zoning laws, urban and rural infrastructures, medicalization, or even about the very definitions of illness and health.²

Based on this definition, the group produced a guide to assist educators in the implementation of the cases and how to discuss race and culture in the classroom.²

Using our learning objectives above, we could construct a patient case to explore a range of issues.  Here is an example of a patient case that a teacher might create:

RS is a 30 YO bisexual African American male with type 2 diabetes, hypertension, and dyslipidemia. He is coming to clinic for the first time since being hospitalized due to diabetic ketoacidosis. His diabetes is uncontrolled and he probably doesn’t have health insurance. His family history includes type 2 diabetes, stroke, and heart failure. He states that he drinks very little water and because he works all the time in a factory, he eats a typical Southern diet: high calorie and high carbohydrates with little to no vegetables. What medication regimen would you recommend in this case? What are some non-pharmacological interventions would you suggest?

This is a suitable case to evaluate a patient newly diagnosed with diabetes however, it does perpetuate stereotypes and can reinforce some implicit biases that many practitioners have. First, in the introductory sentence, it states the patient’s sexual orientation. This information really isn’t necessary to answer the key questions. Nonetheless, patients sometimes disclose personal information during a clinic visit or hospital stay. Although it does not contribute information that is useful when addressing the key questions in the case, it might be an opportunity to introduce students to a patient whose sexual orientation may be different than their own. However, the manner in which the patient’s sexual orientation is included doesn’t flow with the narrative of the case. Also, the case alludes to the possibility that this patient is uninsured, but based on the objectives, we should indicate that the patient is on Medicaid. Lastly, the patient’s diet is described in a stereotypical manner. Instead of labeling this a "southern diet" that all African Americans in the south consume, it would be better to describe the patient’s diet without ascribing it to the patient’s race or ethnicity. So here’s a way to change the case without perpetuating these biases and stereotypes:

RS is a 30 YO African American male with type 2 diabetes, hypertension, and dyslipidemia. He is coming to the clinic for the first time after being hospitalized for diabetic ketoacidosis. He has trouble getting his medications because his Medicaid plan’s limited formulary and normally his boyfriend helps him pay for his medications. His family history includes type 2 diabetes, stroke, and heart failure. When ask about what he has eaten over the past 24-hours, he indicates he did not eat breakfast, he ate a chicken sandwich meal from Chick fil A for lunch, and had fried chicken with bread for dinner. What medication regimen would you recommend in this case? What are some non-pharmacological interventions you would suggest?

The new case removes the patient’s sexual orientation from the introductory statement but its still alluded to it later in the case.  The case introduces access to medications as a potential problem. Also, there is specific information about the patient’s eating habits, rather than sweeping generalizations. These changes do not alter the case entirely, but they do remove some of the stereotypical elements and biases. In order to introduce students to the social determinants of health, social constructs need to be included in patient cases but must be constructed in such a way to reduce biases while reflecting the diversity in the patients we serve.

Cased-based Learning From Two Perspectives: Learner and Teacher

by Madison Parker, PharmD, PGY-1 Pharmacy Practice Resident, University of Mississippi Medical Center

Who enjoys being proved wrong or having to learn the hard way? The rhetorical answer is no one! However, in the last couple of months, it has happened to me time and time again. I recently graduated from pharmacy school. I matched for a PGY-1 pharmacy residency at the medical center associated with my alma mater. Wanting to be a well-rounded pharmacist and a successful preceptor, I decided to participate in an elective academia rotation. I quickly learned how different things are on the “other side.” As a student, I never understood the time commitment and detail that went into teaching a class and developing cases.

As a student, I did not enjoy the “case-based approach.” I did not understand why we were going to school if we were essentially just teaching ourselves. What I didn’t realize at the time was how much I was learning and growing as a health professional by grappling with cases. Hindsight always seems to be 20/20! Case-based learning made me dig far deeper than typical lectures ever did during pharmacy school. I was no longer just memorizing a drug side effect to regurgitate it back on a multiple-choice test. It was challenging, and it made me think well beyond “the right answer.” I had to learn how to pivot when a treatment was contraindicated or what to do next if a patient suffered a side effect.  Essentially, I learned how to contingency plans to better take care of my future patients.

I have also learned about Bloom’s Taxonomy during my teaching experience and the “cognitive skills” that case-based learning requires. Lectures rely on regurgitating information and the goal is to have students “remember” and “understand” whereas case-based learning requires the student to “analyze,” “evaluate,” and “create.”¹

During case-based learning, the student is provided a detailed clinical case or scenario that they need to work through and discuss. This typically involves a small group rather than a large lecture hall. Case-based learning, like typical lectures, should still include learning objectives, but the teacher won’t always disclose all of the objectives before the case discussion occurs.¹ This non-disclosure allows the learner to think for themselves. Case-based teaching dates back to the early 1900s. Dr. James Lorrain, a professor at the University of Edinburgh, was thought to be the first teacher to use case-based teaching during his pathology course. 

One study surveyed health professional students about their opinions toward case-based learning. There were 520 students invited to participate. These students were from various professional schools including medicine, pharmacy, nursing, and social work.  Students were required to work through the cases as teams during the course. Students were given a nine-item survey that asked about their satisfaction with small-group, case-based learning format using a 7-point semantic differential scale. The students were asked to rank each point from 1-to 5 where 1 indicated ‘strongly disagree’ and 5 indicated ‘strongly agree.’ Ratings were reported as a mean: e-learning discussions (3.54 ± 0.99), small group learning experiences (3.94 ± 0.88), and panel discussions (3.76 ± 0.91). Based on student satisfaction scores, one can infer that case-based learning can be challenging but also rewarding for the learner.³

Another study examined medical students in their pre-clinical years from 2015-2018 at Stanford who chose to enroll in an optional case-based learning course. This course was led by a facilitator and involved a small group of students who would discuss a prospective patient case. At the end of the course, the medical students were asked to participate in a pre-and post-intervention study reflecting on their clinical skills. The control sample included medical students who did not participate in the course. Non-participants were encouraged to participate in pre-and post-intervention surveys as well. A 14 item survey was given to assess participants’ self-reported skills including the ability to report, interpret, manage, educate, and course-specific skills and objectives. A 5-point Likert scale was utilized with 1 indicating ‘strongly disagree’ whereas 5 indicated ‘strongly agree.’ Two surveys were administered; the first survey was completed within two weeks before the first session of the optional course, and the second survey was completed within 2 weeks after the final session. The difference between the post-intervention score and pre-intervention score was calculated. The intervention group resulted in a more positive change in the following categories: understanding how clinicians arrive at a diagnosis, using a step-by-step approach in a longitudinal primary care setting, and how to ultimately share information with their patients.⁴

There are many benefits associated with case-based teaching. It challenges health professional students to use their problem-solving skills before encountering real patients in their clinical years. This in turn allows students to practice and sharpen their skills so that they know how to grapple with real problems and challenges using the same resources that practitioners use when faced with the unknown.⁴ As a future preceptor, I am a big fan of case-based teaching!

In my opinion, cases should be created by experts in the field of practice. Cases should be constructed in a way that they spark students’ interest when hearing about “the real world.” Case-based learning should be facilitated, but by whom? In my experience, it doesn’t have be an expert in the field, just someone with a general knowledge of the subject matter. However, it is helpful for facilitators to have a guide created by the case author.  The case guide should clearly state the objectives the students should acheive and give “tips for success” in the written matters.

In summary, case-based teaching is effective and encourages higher order thinking. It is particularly effectives in health professions education, giving students a chance to practice in a safe environment where “no harm” will arise from a poorly conceived or ill-informed decision. Case-based learning should be extensively used in every health-related curriculum as the benefits and positive results are well established.

Assisting Students with Disabilities During Experiential Education

by George Lamare Haines, PharmD, PGY1 Community Pharmacy Resident, The University of Mississippi School of Pharmacy

There is only one way to look at things until someone shows us how to look at them with different eyes.

—Pablo Picasso

At times it is hard to see problems that face others. Often, when a problem doesn’t affect a person, they don’t perceive it as a problem or that it exists because they don’t have to deal with it. This is certainly true when it comes to people with disabilities. There are many things that an able-bodied person takes for granted and never even considers. When it comes to students in college, title II of the Americans with Disabilities Act (ADA) protects people with disabilities from discrimination by universities, community colleges, and vocational schools.¹ Most of us are at least somewhat familiar with accommodations for students with disabilities in the classroom setting, but it is far less common to see these considerations in experiential learning environments.

Every educator tries their best to determine the most appropriate teaching methods for the largest number of students. For most programs, there are special accommodations made for students with learning disabilities in the classroom, like providing extra time during testing or having someone read the exam questions aloud. When students with disabilities enter professional programs, they will be required to participate in experiential education that places them in environments similar to those that they will work in after completion of their program. These “non-academic” settings, which are not under the control of the university or college/school, can be challenging for students with disabilities.

When the University of Colorado School of Medicine was faced with this, they took steps to ensure that their students were set up for success. To illustrate, the school made special accommodations for a third-year medical (M3) student who uses a wheelchair. The student was scheduled to start an Operative/Perioperative clerkship. Before the start of the student’s M3 year, the student met with the medical school dean to discuss requirements, barriers, and reasonable accommodations for the clerkship. The dean then met with preceptors for the clerkship to inform them of the student’s disabilities and to develop a plan for an optimal experience, which included selecting clerkships that would allow for maximal physical access and participation. By putting in this extra effort, the student was able to fully participate in all required clerkships and went on to complete the degree with honors.²

Due to the student’s proactive behavior, there was effective communication and reasonable accommodations made so that they could complete their clerkship. Early communication is the key here. As with most issues, if they are addressed as early as possible, the issue can be addressed before it causes real problems. Often administrators have to do the groundwork to ensure that learners with disabilities are able to complete the requirements of an experience. These steps are important for both physical and learning disabilities. Students with learning disabilities are often hesitant to report these since there is often stigma and shame. Or they may not understand the impact of their disability and the potential benefits of sharing the information with their preceptors.³

Preceptors and faculty in experiential education administration can determine reasonable accommodations for students if they are given adequate time, resources, and knowledge of the disability.⁴ There are five basic principles that should guide institutions to ensure that reasonable accommodations are provided. The accommodations should be based on a reliable diagnosis; they must mitigate factors of the disability that affect student competencies; it should be tailored to each experiential site; they must ensure collaboration and communication occurs between the students, staff, preceptors, and administration; and most importantly, it must uphold privacy. If the accommodation takes away from any of these, it can not be considered reasonable.⁴ Often, accommodations for a student with a learning disability can be made by minor adjustments to the environments, policies, and procedures. Students with physical disabilities may require significant adjustments in the environment.  By having proactive policies and procedures in place, preparing preceptors for what to expect, and monitoring student learning outcomes, students with disabilities have the best chance for success during experiential education.⁴

A recent commentary published in the American Journal of Pharmaceutical Education provides a stepwise approach to addressing these needs.⁵ The first step is to create a system for students to submit a request when entering the experiential program. Once the student has submitted the request, the program is then responsible for exploring accommodation options and sites that either already meet the requirments of the accommodation or that can reasonably accommodate the request. The next step would be applying and fully implementing these accommodations. This will look different for different locations and will depend on the needs of the student. For example, a student who does not have sufficient strength may be accommodated by shortening the length of the rotation day but extending the total number of days in order to meet the required number of experiential hours. Another example would be to avoid rapid-fire questioning for a student that struggles with processing information.⁴ A practice walkthrough by both the student and preceptor may also be useful before the start of the rotation to allow the student to familiarize themselves with the environment and what to expect when they start the experience. The final, and possibly most important, step is to monitor the effectiveness of the accommodation. Continued communication between the preceptor, student, and experiential program director is essential to quickly address oversights and ensuring the accommodation is effective.⁵

When we start looking at these required experiences from the student with a disability perspective, we see problems that we didn’t know were there. It takes students with courage to tell you what their needs are. Open, honest communication seems to be the key to addressing the needs of students with disabilities, especially in experiential education.

Should We Adopt a Two-tier Grading System in Health Professions Education? Benefits and Practical Considerations

by Mary Kathryn Vance, PharmD, PGY-1 Pharmacy Practice Resident, University of Mississippi Medical Center

Grades have long been a cornerstone of educational systems, giving students and educators a way to measure the achievement of learning objectives within courses. Grades were first instituted in the 1700s in Europe to assign a rank order among students. By the late 1800s, several American universities had adopted a grading system with “passing” rates ranging from 26-75%. Eventually, this transitioned to the tiered grading system we recognize today, where an A generally means the student has scored at least 90% on the assessment (or received >90% of available points in the course), a B means 80-90%, a C means someone scored in the 70s, and so forth. Grades typically are attached to a descriptor.  For instance, an A might signify an exceptional level of achievement, a B good but not outstanding level of performance, a C a fair level, and a D signifies significant performance deficiencies but still passing.¹ While this is still the system widely employed by the majority of Doctor of Pharmacy programs in the United States, some programs have adopted a pass/fail or two-level grading system.

Several studies have shown that students in health professions programs, including pharmacy students, experience anxiety, depression, and stress at higher rates than their peers. This places students at a higher risk of developing burnout, which is characterized by exhaustion and a diminished sense of accomplishment.^2,3 Moreover, multitiered grading systems can foster unhealthy competitive environments among students. Two-level grading systems have been proposed as a potential way to mitigate stress, reduce competition, and increase students’ well-being. A survey with nearly 1200 first- and second-year medical student respondents found that students in schools using grading scales with three or more categories had higher levels of stress, emotional exhaustion, and depersonalization when compared to students in schools using two-level grading systems. Students in schools with multi-tier grades were also more likely to have seriously considered dropping out of school.⁴ Another study conducted at Mayo Medical School compared students from classes before and after implementation of a two-level grading system. Students graded with the two-level system had less perceived stress and greater group cohesion than their multilevel peers.⁵

One concern that educators express about two-level grading systems is that they can negatively impact academic performance. Students’ motivation to learn the material might be decreased because they may not have to understand the concepts as deeply to get a passing grade. Some evidence suggests this concern is more theoretical than true. At the University of Virginia School of Medicine, the first two years of the curriculum were changed from graded to pass/fail. When student performance was compared before and after the change, no differences were observed in subsequent course grads, grades during clerkships, or scores on the United States Medical Licensing Examination (USMLE) Steps 1 and 2 Clinical Knowledge boards.⁶ Similar results were seen at the Mayo Medical School — there was no difference in USMLE Step 1 board scores before and after changing from a multilevel to a two-tier grading system.⁵

While they do not appear to reduce students’ achievement during school, two-level systems may better position students to become self-regulated learners. Health professionals are expected to engage in a process of continuous learning throughout their careers. This may be difficult for some students after transitioning from a system with strong extrinsic motivators (i.e. grades) to professional life where the individual must muster the internal motivation to figure out what, how, and when to learn. Helping students develop into self-regulated learners while still in school lays the foundation for this to continue throughout their careers and ultimately increases their knowledge and skills to provide better patient care.⁷

Another potential disadvantage of two-level systems is a decreased probability for students to match with residency programs. The American Society of Health-System Pharmacists (ASHP), the organization that is responsible for pharmacy residency program accreditation, will soon be requiring that all accredited pharmacy residency programs develop procedures on how to evaluate the academic performance of applicants from pass/fail (two-tier grading) institutions.⁸ There is still the potential that students from institutions that have two-tier grading systems could be seen as less desirable or competitive. However, this effect was not seen in a study that examined the effect pass/fail grading on advanced pharmacy practice experiences (APPEs) had on residency match rates at 100 pharmacy schools in the United States over the course of 3 years.⁹ Unadjusted analyses showed that there was no difference in match rates between students from schools with multilevel and two-level grading systems. After adjusting for potential confounders, two-level grading was actually associated with higher match rates during one of the three years.⁹ Similar rates of success in residency placement were also seen in the study conducted at the University of Virginia School of Medicine before and after their transition to a two-tier grading system.⁶

Despite the potential benefits, two-tier grading systems have not been widely implemented in pharmacy education and when it has been implemented, they are some inconsistencies. A study examining the implementation of two-tier grading systems within Doctor of Pharmacy programs found that the programs varied in the terminology used to describe student achievement levels, minimum pass levels, and whether a class rank or GPA was calculated, among other factors.¹⁰ This lack of uniformity leads to questions as to how best to implement two-tier grading systems.

Experiential courses such as introductory and advanced pharmacy practice experiences would seem to lend themselves well to a two-tier grading system. These types of courses tend to vary in their rigor and requirements based on the practice site. This can make interpreting and interpreting letter grades assigned to a student’s performance is already difficult. There are a variety of labels that could be used in a two-tier system, such as pass/fail, pass/no pass, or satisfactory/unsatisfactory. These labels haven’t been evaluated, but the connotations with “fail” and “unsatisfactory” would seem to be more negative than “no pass.”

Converting non-experiential courses to a two-level system is controversial. In schools where this has been done, numerical grades given to assignments and assessments are used to calculate a student’s class rank. This could allow high achievers to be rewarded and give residency programs a way to compare applicants. We clearly need additional studies about two-tier grading systems to determine their benefits and risks and how to best execute them.

Backchannel Communication to Improve Instruction and Learning

by Claire Calcote, PharmD, PGY1 Pharmacy Practice Resident, St. Dominic Jackson Memorial Hospital

If you are unfamiliar with backchannel communication, it involves using secondary ways to communicate “behind the scenes” of the primary method of communication, like during a lecture presentation. Its use within higher education has grown exceptionally, even before the COVID-19 pandemic. Backchannels have always existed within the classroom - like passing notes or private conversations with a nearby classmate. Now, multiple platforms allow students to submit comments, ask questions, or share supplemental materials without interrupting the primary communication channel (e.g., the teacher’s presentation). Essentially, the discussions and thoughts already occurring within the classroom are given an open environment to foster dialog. These channels don’t cure all problems - like distracting outside conversations, disengaged students surfing non-educational websites, and reserved learners who hesitate to ask for clarification or further explanation. However, a backchannel can create an additional outlet for discussions, engage both introverted and extroverted students, and reveal gaps in learners’ comprehension, which ultimately enriches instruction and enhances learning.

Several benefits of secondary communication through backchannels have been documented.^2,3 By providing an additional outlet for discussions and participation, student engagement is enhanced.² Backchannels also provide opportunities to engage those who are less likely to speak up during lectures or ask questions. Group collaboration can be facilitated when a backchannel is used.³ Additionally, these platforms foster an open environment for exchanging resources. Students can comment and clarify misunderstandings regarding lecture content.  And faculty can respond if needed.² This ultimately builds teamwork and collaboration skills, which are important outside of the classroom. Lastly, from an instructor perspective, the backchannel can reveal gaps in student comprehension, so efforts can be made to review or refocus specific content.³

While it is unclear when backchannel communication using modern technology first occurred, its formal use was described in the early two-thousands.¹ In 2006, a paper described a backchannel communication method using online chatrooms during graduate courses at the University of California, Berkley over a period of two years. Authors analyzed over 200,000 chat room entries, plotting chatroom communication over time to assess utilization trends.¹ They concluded that participation increased over time, with a small number of students participating most frequently.¹

I recently had some experiences working with a backchannel communication method during a course where I was the teaching assistant.  I wondered — is there a relationship between course performance and backchannel engagement? During this four-week course for second-year Doctor of Pharmacy students, a backchannel communication was available using a tool called Discord which includes Voice over Internet Protocol (VoIP) messaging, instant messaging, and digital media distribution platform. The instructor created a separate sever within Discord and enrolled the entire class, including teaching assistants and other faculty who contributed to the instruction. Additionally, students were assigned to small groups in the Discord community for active learning activities and other assignments throughout the course. During each class session, students had required to complete assignments or assessments that involved communicating with their group members in Discord. Individuals often used the general chat feature to communicate with other members of their group, the teaching assistants, and the instructors. Discord possesses helpful features like private messaging and both audio and video calling; therefore, students can contact anyone in the community to get clarification.  The system also provides a mechanism for urgent notification if emergent situations arise. Since Discord is popular among the gaming community, a select number of students were eager to engage on Discord as they were familiar with the platform.

During the first few days a majority of the class seemed hesitant to engage on Discord outside of the required in-class activities. However, as the course progressed, open discussions about lecture content occurred, with some students exchanging graphics and primary literature articles. Additionally, encouraging reminders before exams and amusing captioned pictures were exchanged between students and faculty. Students took the initiative to create topic-specific threads within the platform to organize the discussions for exam preparation. The experience aligned with the University of California, Berkley’s findings – backchannel communication participation increases over time, with a select number of individuals engaging the most.

By the second week of the module, particularly following the first exam, students were more likely to directly contact and communicate with the lead instructor and other faculty members. Questions became more specific and targeted as students began to study the materials. From a class administration perspective, in the event of a student emergency, participants were able to notify the faculty through Discord and devise alternative ways for the student to receive the instruction materials. These direct communication features were appealing from a faculty point of view, as they served as a more immediate way to communicate (when compared to email) and messages could be sent without disclose personal information. Platform use persisted until the conclusion of the four-week course, with students continuing to discuss and clarify lecture content prior to their final exam. After grades were finalizing, it was noted by the lead instructor that those who engaged the most within the backchannel were the highest performers within the course.

My observations coincide with experiences reported in a 2020 case study at the University of Aizu in Aizuwakamatsu, Japan.⁴ Professors used external personal social networking systems (SNS) like Twitter, Facebook, and Line for backchannel communication, which allowed students to interact and collaborate on assignments. Participants included those in four Japanese undergraduate English as a Foreign Language (EFL) courses and they were observed over one academic year.⁴ Interaction via the backchannel could be in any language of the students’ choice.  Initially, participants were hesitant to use the various SNS options for backchannel communication; however, reluctance was overcome once students realized the privacy of the backchannel. The study ultimately concluded that backchannel communication provided a comfortable outlet to engage with other classmates who they most likely would not interact with face-to-face.⁴

Backchannel communication can be used to overcome various classroom obstacles. Although multiple platforms exist, a single backchannel would be easier for faculty to maintain, monitor, and respond to. Students will need to learn about backchannel communication etiquette and faculty will need to set expectations on when and how to use the system.  Ideally, the backchannel would be used during the main channel (e.g. the lecture time) to prompt student engagement. This should be continued through several lectures to overcome potential participation hesitancy. Additionally, instructors should routinely send prompts in the backchannel that requires student response or collaboration related to the learning objectives of the course.  Creating a backchannel communication channel can increase classroom discussions, heighten student participation, and reveal misunderstood content.  In so doing, instruction and learning are ultimately enhanced.
