Why I Use and Write Open Textbooks by Dr. Oscar Levin, UNC Associate Professor

It is easy to go with one of the "standard" textbooks for your class, especially when the publisher's rep takes you out to lunch and describes all the fancy new features that their online homework systems and ebook now offer (you probably won't use these, but its nice to know they are available).  It is easy to convince yourself that, even though students might have to by over $200 for the book, the price of the book will eventually be worth it to students, given the wealth of information it contains (maybe they can find a used copy). And it is easy to use the textbook as a pedagogical backstop: to teach your class like you would anyway, leaning on your own expertise, and then being surprised when students struggle (did they even read the textbook?).

The above certainly doesn't describe everyone, but it did describe me about five years ago.  The possibility of using Open Textbooks allowed me to reflect on the way I used, and didn't use, textbooks in my teaching.  Partly because few students would read the textbook ahead of time, and partly because I wanted to give my students value beyond what they could buy in a book, I had drifted away from using textbooks as anything more than a course outline and repository for homework problems.  These functions do not require students have a textbook, so why have a textbook at all?  The solution: if the textbook is free for students, there is no harm in adopting it.  There is no harm in adopting multiple books or to writing modules to cover material books don't get quite right.  After a few semesters, these materials can be compiled into one coherent textbook tailored perfectly for our students.

What I describe here might not be easy, but we should take up the challenge to improve the educational experience of our students.

The traditional proposition for using OER in modern classrooms focuses on the reduction of costs associated with purchasing educational materials. Another common advantage of OER is the promise of “democratization of knowledge” – a proposition that OER allow audiences outside the confines of formal degree programs access to learning materials.

Undoubtedly, both of these aspects of OER are powerful factors driving growing rates of OER adoption in higher education, including at UNC.

However, when it comes to the fields that are data- and time-sensitive such as finance, OER offer another benefit that works well with the core objectives of modern education. That benefit is being able to deliver accurate, up-to-date, sector-specific, and jobs-market focused applied content that traditional commercial textbooks and course materials simply cannot match. 

News and data flows are at the heart of business education

In business, news flow – a flow of time-sensitive and materially important information – forms a core part of decision making. In finance, that decision making covers higher levels of management. Fund managers define investment strategies tailored to opportunities and threats presented in the news flow. Institutional investors, corporate CFOs and financial analysts must track the evolution of news and react to it both tactically and strategically.

Data and news flows also reach back and front office mid-managers, traders, investors, portfolio and asset management support specialists, and corporate project finance professionals, and treasury managers. Take any financial institution, from a local credit union to a globally-trading specialist hedge funds, their daily operations are anchored to news and data. The news flow is woven into financial analysis, modeling and decision-making both ‘vertically’ (across the model inputs) and ‘horizontally’ (across time). It serves to confirm prior strategical and tactical knowledge and to test this knowledge against possible changes in the conditioning and causal relationships. 

Change defines finance

Crucially, in finance, axiomatic, theoretical and empirical foundations of our knowledge are subject to frequent and disruptive changes.

This means that news flow in finance and in business is not just the noise of the media. It is a flow of “hard” quantitative data that materially influences asset values, expected future returns on investments, R&D, Mergers and Acquisitions, market expansions, marketing, strategic changes in management, talent acquisitions, and so on. It is also a flow of “soft” qualitative information, such as statements, disclosures, warnings, company or policy communications, and more. 

Just as our information flows become broader, deeper and more complex, the tools we use in integrating news flow into our business decision-making also change. Rapidly. In academic finance, we are seeing adoption of new research tools and methodologies that displace prior norms of analysis every decade or less. Finance is always the frontal point of new technology adoption in business decision-making. 

This is not what is expected to happen in many other disciplines of inquiry, where the rates of change are more slow, more predictable. There are many epistemological reasons for this, but reality is that the core body of knowledge in natural sciences is changing more gradually and less dynamically than in social sciences. The same change is even faster in finance than in any other sub-discipline of business.

OER: challenging epistemological biases

In the lecture halls, this means that financial course materials and engagements must integrate news flow, and anchor key analytical concepts and frameworks to information and data flows. These data and events that generate them must then be tested across time and models, with a common expectation that it might fundamentally alter our understanding of and experience with the world around us. The use of these frameworks and analytical methods must then be integrated into applied sector-specific body of knowledge and aligned with modern workplace tools.

Put simply, a textbook written in 2019, and updated in 2023 is out of the news flow by the time it hits the reviewers’ desks in 2024. Worse, as it passes through the filters of epistemological biases of its authors, reviewers and publishers, it faces just two options for survival through to publication. Option one: it can evolve into a generic, high-level text covering only broadly consensual and largely outdated frameworks. Option two: it can focus on highly technical and specialist aspects of our body of knowledge that make them relatively immune to reviewers’ and publishers’ biases, at the expense of giving up on being timely and skills-focused. The best textbooks in finance fall into that second trap: they are technically flawless, yet practically outdated, highly theoretical and poorly targeted to applied skills sets.

Inevitably, these texts fail to meet the test of everyday reality/news flow.

Take one example. Almost all literature on the subject of investments and portfolio management focuses on the well-publicized regularity that gold and bonds act as “risk diversifiers” to stocks. In other words, during stock market turmoil, we come to expect – and this is the subject matter of traditional textbooks on the subject – that investors selling stocks will move their funds into government bonds and gold. 

This “flight to safety” movement prevails in almost all historical episodes of major stock market corrections, which is commonly noted in the textbooks – except for the never-discussed experience of the Global Financial Crisis, when the selloff in stocks led to waves of investors selling bonds and gold. This is not covered in the textbooks not because the authors are ignorant, but because the Global Financial Crisis was so violently challenging to the prevalent norms of established finance, it is deemed to be too anomalous to be worthy of coverage.

Zoom to the market turmoil in the second week of April 2025. Stocks crashing, and gold and bonds are selling off too, at least in the very first day of the announced tariffs. Thereafter, gold rose, bonds continued to fall and stocks at first tanked, then rebounded. Is anomalous becoming the new norm? You wouldn’t know it if you consulted the commercially published textbooks full of mathematical models, and short of critical analysis that traders and investors need in the real world. 

Yet, my OER-utilizing course, BAFN479 Portfolio Management, was fully enabled to deal with these types of events precisely because it is not anchored to a singular textbook. Instead of focusing on tracing out one source of materials, we use weekly-updated lecture notes, specialist data sources, and analytical files that cover high level frameworks that many traditional textbooks would do, but go beyond these. Where textbooks use stylized examples and long-dated historical data to work through conceptual definitions and analytical tools, we use real-time, real-world data and we overlay it with actual news flow. That allowed us, for example, on April 9 to discuss in class the events in the gold, bond and stock markets in the context of actual institutional portfolios. It also allowed us to extend key tools of theory and modern portfolio strategies to the concepts of financial hedges and safe havens that are current to the modern practice and research yet are never consistently covered in the textbooks.

This ability to transcend the orthodoxy of “established” business, financial, and economic body of knowledge, to challenge the prevailing narrative using key tools and timely news and data flows is the key benefit of OER to the lecture hall. The power to link today’s information to current decision making without having to graft both onto the old trees of  past knowledge is the promise of OER in the lecture hall. Keeping the subjects we teach current, immediately reactive to the reality of business and financial environments around us is more than an opportunity to teach better. It is an opportunity to enable our students to face real world challenges not as an auxiliary example to the textbook, but as the core part of our classroom engagements.

Stepping into my new role as a Graduate Assistant focused on Open Educational Resources (OER) has been a profound and eye-opening experience. As a first-generation undergraduate and graduate student from Ghana, a developing country, where access to educational resources is often limited, working with the OER team at UNC has shown me the transformative power of open education. Not only does it challenge the traditional models of learning, but it also offers the potential to change lives by making education more equitable and accessible.

Being a first-generation student from a developing country comes with its own set of challenges. Education has always been seen as a luxury in my community, rather than a right. Textbooks, research materials, and even basic access to information are often out of reach for many students like myself. As I pursued my undergraduate and now graduate degrees, I have always been aware of the financial burden that textbooks and learning resources can place on students. It is not uncommon for students back home to rely on outdated textbooks, shared among classmates, or to go without the materials they need to truly succeed in their studies. This has fueled my passion for exploring alternative approaches to education—ones that do not exclude students based on financial capabilities.

I was fortunate to join the OER team as a Graduate Assistant, a role that perfectly aligns with my passion for education and advocacy. Before joining this team, I had no idea how far-reaching the concept of OER could be. In my home country, the idea of freely accessible, high-quality educational resources is still in its infancy. The cost of textbooks and academic materials is a significant hurdle for many students. For this reason, being part of an OER initiative in a more developed context has truly opened my eyes to the potential impact OER can have, not only in the U.S. but globally.

The primary focus of OER is to provide students with the resources they need to succeed without financial strain. In countries like mine, where families struggle to cover basic living expenses, the cost of textbooks can often be overwhelming. OER help bridge this gap by ensuring that no student is denied access to quality educational resources due to cost. These resources are designed not only to reduce costs but to improve educational outcomes by making up-to-date materials more readily available. The ability to access educational resources without the need for expensive textbooks means that students can focus more on learning and less on how they will afford the next book.

While OER is making great strides in developed countries, there are still significant challenges in introducing these resources to less developed nations. Many countries, including my home country Ghana, face infrastructure issues, such as limited internet access and outdated technology. These problems can prevent students from fully benefiting from the wealth of free resources that OER offer. However, the potential for change is tremendous. With increased awareness and support, we can begin to introduce OER in my home country and others like it. As I continue to grow in my role, I am committed to advocating for the integration of OER in developing countries. This will require collaboration between governments, educational institutions, and organizations dedicated to promoting open access to education. By building awareness around OER and creating the infrastructure to support it, we can take meaningful steps towards a more equitable and accessible educational future.

My journey as an OER Graduate Assistant has only just begun, but I already feel a deep sense of purpose in this role. Education has the power to uplift individuals and transform communities, and OER are critical tools in making that happen. As I continue to work with the OER team, I look forward to being part of this global movement for change, one that prioritizes the needs of students and breaks down the barriers that have traditionally stood in the way of educational success. OER have shown me that education does not need to be restricted by financial constraints—it can and should be available to everyone, regardless of where they are in the world. I am excited to bring this knowledge back to my home country, where I hope to be part of the movement to promote OER and ensure that every student has the opportunity to succeed.

Open Educational Resources represent more than just a cost-saving initiative—they represent a fundamental shift in how we view education. OER remove barriers, level the playing field, and ensure that all students have the opportunity to reach their full potential. I look forward to continuing my work with the OER team and contributing to this global vision for a better, more equitable educational landscape.

As an instructor, I have adopted a variety of textbooks and supplemental materials to teach courses in Psychology, Neuroscience, Anatomy, and Physiology for undergraduate students, graduate students and medical students.  For a long time, my perspective was solely on adopting materials that were most aligned with my course objectives and that best assisted me with instruction.  However, being at UNC over that past few years has brought the cost of course materials into the forefront of my mind, as I have more freedom when choosing my course materials and I’ve learned that many UNC students have difficulty finding the funds for course materials.  I’ve met very friendly, helpful, and genuinely concerned publishing company representatives that care about cost, but the student-centered approach is lost in the understandable motivation of profit within the corporate structure of publishing companies. 

Publishing companies are doing a great job at staying relevant by creating textbooks in a variety of formats, providing supplemental instructor materials and test banks, and by integrating web-based active learning activities such as adaptive learning modules.  This is very enticing for instructors, as this can significantly improve the quality of course materials with less effort.  In addition, some publishing companies further entice by providing ‘bulk’ discounts and by packaging OER with significantly reduced price.  Although this sounds like a great option for students, they’re essentially charging for OER and the ‘bulk’ discounts only apply if you use their products, which may exacerbate the monopoly certain publishing companies already have on the industry. 

The solution, perhaps OER, but there are many obstacles for OER to be able to compete with publishing companies.  First, OER need to be well organized, properly vetted, and easily accessed, perhaps through a centralized system. One of the benefits of adopting materials from publishing companies is that they are most likely written by experts and have been scrutinized through peer review, meaning instructors can be more confident that the materials are accurate and easily incorporated into their courses. Second, since textbooks are often written, edited, and reviewed by academics, there needs to be a concerted effort to recognize this contribution to their field and to higher education, not just for the creation of OER, but also for adopting and modifying OER.  Tenure and Promotion is the obvious place to consider, but from my experience, there is not enough weight placed on the amount of work it takes to adopt OER, let alone create OER. 

So, if you’re a Dean, Chair, Director, or Faculty, I encourage you to keep looking for ways to incentivize the creation and adoption of OER, and if you’re an Instructor, I encourage you to give it a try.  You can start small by incorporating OER into a portion of your course, then you can add more and make modifications during subsequent semesters.  Also, consider applying for UNC’s OER development grants awarded to UNC by the Colorado Department of Higher Education.
