Knowledge and teaching in the age of information

Knowledge and teaching in the age of information

The advent of the World Wide Web in the turn of the last century completely transformed the way most people find and absorb information. Rather than a world in which information is stored in books or housed in libraries, we have a world where all of the information in the world is accessible to everyone via computers, and in the last decade or so, via their handheld mobile device. The young people currently in university or in school grew up in a world where information is not privileged and immediate access to all of it is taken for granted. In this age of immediate and readily accessible information on any subject, we must ask: What is the role of academic institutions in teaching? If anyone can find out anything at any time, why learn anything? Is there any value to knowledge in its own right?

The answer is that of course teaching and learning are still important, but they must change to reflect the way information is accessed. The fact is that information on its own is useless without a contextual framework. It may be possible to easily find a detailed account of all of the units and commanders that participated in the Battle of Regensburg in 1809, but if the reader has no understanding of military history, and no background on the politics leading to the Napoleonic wars, this information is no different from a shopping list. Similarly, it may be possible to find detailed information on the excretory system of annelid worms, but without an understanding of what excretory systems are and what their role is in the organism, and without a knowledge of the biology and evolution of annelid worms, this information is no more than a list of incoherent technical terms.

These two very different examples serve to highlight the difference between information and knowledge. Possessing knowledge about a subject means being able to place information into a broad framework and context. People who are knowledgeable about the Napoleonic wars do not necessarily know the names of every commander of every unit in the Battle of Regensburg, but if they need this information, they can access it and use it better than someone with no knowledge. A comparative zoologist may not know all the details about annelid excretory systems, but when needed, they will know what to look for.

With this distinction in mind, I suggest that teaching and textbooks need to shift their focus from transferring information to transferring knowledge. No textbook can compete with the wealth of information available at the students’ fingertips. No course can ever impart all that there is to know about a subject. However, a good teacher and a well-written textbook can provide a much better framework for knowledge and understanding than a search engine will ever be able to. Indeed, a course or module that overburdens the students with numerous bits of information is not only a misuse of resources, it is ultimately counter-productive, as the student will always be able to challenge the teacher with a new bit of information not included in the course.

Teaching in the age of information should focus on providing a working vocabulary of a subject and on building a robust framework of knowledge. Detailed examples can be used to demonstrate principles, but this should be done sparingly. The curious students can then fill in the details on their own, taking advantage of the information at their fingertips.

I have been following these principles in my teaching of evolution and organismic biology for as long as I have been a university professor. My frustration at the details-heavy zoology textbooks led me to write a new textbook, focusing on principles and on providing a conceptual framework to organismic biology, rather than on details. For example, I have written a chapter on excretory systems that outlines what the roles and functions of this system are, and gives a few demonstrative examples of how these functions are manifested in a small number of organisms. I have included similar chapters on other systems interspersed with chapters on individual animal phyla, which give an overview of the phylum and its diversity, and present the specific variations within each of the organ systems, and how these are adapted to the life history of members of the phylum.

As we and our students continue to have easier and more readily available access to information, this new approach will provide a more successful framework for students to continue to grow and learn as they step out into the world. Hopefully this approach will be picked up by authors of additional textbooks to provide a new generation of teaching resources, more suitable for the age of information.
