It breaks my coronary heart when the prices of college-level textbooks are labeled as “junk charges.” Or, when individuals complain that at the moment’s textbooks are “overstuffed, chopped-up monstrosities” which are boring and do little to advance pupil studying.
But all this angst over textbooks misses these essential details:
Textbooks present a fastidiously curated physique of information.
Textbooks have to be practically 100% correct.
Textbooks supply the view of an knowledgeable educator. Their high quality can’t be in comparison with the free content material that we discover on-line.
It’s time to reaffirm the indispensability of textbooks’ high-quality curated information for educating the following era— whereas shifting them into a contemporary digital context and making them higher on the similar time.
Digital know-how makes it potential to enhance the readability, precision and utility of a textbook. A course of often known as “information engineering” powers these enhancements. It includes a scientific alternative of ideas, a rigorous mapping of the relationships between these ideas and logical definitions that enable them for use by synthetic intelligence and understood by people.
Authoring textbooks in order that their ideas will be learn as pc code will usher in a metamorphosis of publishing know-how probably higher than the event of Gutenberg’s printing press. We must always embrace this course of now.

Take into account an illustrative utility of this concept. Whereas writing a biology textbook, we will logically outline two organic phrases as follows: A Eukaryotic cell is a cell that accommodates a nucleus surrounded by a membrane. An enzyme is a macromolecule that performs the function of a catalyst and has the operate of reducing the activation vitality.
Within the definitions above, “Eukaryotic cell,” “nucleus,” “membrane,” and “enzyme” are ideas which have meanings particular to biology; “is a,” “accommodates,” “performs,” and “has the operate” describe relationships. The ideas and relationships taken collectively are known as a “managed vocabulary,” and they’re utilized throughout the entire e book. As soon as the managed vocabularies are created, they can be utilized to introduce extra complicated ideas.
The straightforward act of utilizing a managed vocabulary is significant for studying any complicated subject. In a topic similar to biology, college students must grasp hundreds of recent phrases. Different complicated fields, similar to regulation, finance and drugs, aren’t any totally different.
Data engineering is just not a brand new concept — library scientists and linguists often observe it. The creators of the “Longman Dictionary of Modern English,” for instance, engineered it in a manner that over 70,000 phrases will be outlined utilizing a core vocabulary of solely 2,000 phrases.
Books are linear whereas information is just not. Mapping of relationships throughout vastly totally different matters makes studying thrilling and helps many novel capabilities, together with exact connections throughout chapters, visualizations at a number of ranges of element and the event of textbook knowledgeable chatbots that may reply college students’ questions on the fly.
As an preliminary check of this strategy, a crew led by SRI Worldwide authored a number of chapters of a biology e book. The ensuing “clever textbook” was examined in a pilot research. SRI reported that the common homework and check scores of scholars utilizing the clever textbook have been 10 p.c greater than these of scholars utilizing the common textbook.
Related outcomes have been noticed in a monthlong classroom trial of the clever textbook led by Lena Tibell of Linköping College. Throughout the trial, college students’ germane psychological load — an oblique measure of studying — elevated considerably. This indicated that the scholars have been studying far more. On the College of Pittsburgh, Professor Peter Brusilovsky has proven the effectiveness of information engineering for an info retrieval textbook.
Data engineering additionally allows us to create concept-checkers for textbook authors which are extra highly effective than spell-checkers. For instance, an creator can ask the questions: Have any ideas or features been neglected of the textbook? Are any idea definitions inconsistent? This sort of help is unimaginable utilizing present authoring instruments.

Nonetheless, creating such textbooks won’t be cheap. Additionally it is not at all times potential to present a logical definition for each idea in a textbook.
Our potential to present logical definitions usually ends on the boundary of present information. Reaching these boundaries can be utilized to immediate marvel and curiosity. For instance, one organic idea that’s troublesome to outline is “Life” itself. To outline such ideas, we should articulate exceptions and a number of factors of view.
To grab these alternatives, we’d like a sustained effort to overtake the authoring of textbooks utilizing information engineering. For optimum near-term impression, we must always start with textbooks for gateway programs similar to biology and psychology.
We should practice and nurture a brand new occupation of information curators for curricular assets to allow this transformation.
Most significantly, the textbooks of the long run should proceed to protect and talk the information of the perfect educators of our era much more precisely and exactly than earlier than. Such textbooks, utilizing the self-discipline of information engineering, can help the curation, preservation and studying of all types of human information.
