It breaks my coronary heart when the prices of college-level textbooks are labeled as “junk charges.” Or, when individuals complain that right now’s textbooks are “overstuffed, chopped-up monstrosities” which might be boring and do little to advance scholar studying.
But all this angst over textbooks misses these essential details:
Textbooks present a rigorously curated physique of data.
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 data for educating the following technology— whereas transferring them into a contemporary digital context and making them higher on the similar time.
Digital expertise makes it potential to enhance the readability, precision and utility of a textbook. A course of often known as “data engineering” powers these enhancements. It entails a scientific alternative of ideas, a rigorous mapping of the relationships between these ideas and logical definitions that permit them for use by synthetic intelligence and understood by people.
Authoring textbooks in order that their ideas may be learn as laptop code will usher in a change of publishing expertise probably better than the event of Gutenberg’s printing press. We should always embrace this course of now.

Think about 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 incorporates a nucleus surrounded by a membrane. An enzyme is a macromolecule that performs the position of a catalyst and has the operate of lowering the activation vitality.
Within the definitions above, “Eukaryotic cell,” “nucleus,” “membrane,” and “enzyme” are ideas which have meanings particular to biology; “is a,” “incorporates,” “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 guide. As soon as the managed vocabularies are created, they can be utilized to introduce extra advanced ideas.
The easy act of utilizing a managed vocabulary is important for studying any advanced subject. In a topic akin to biology, college students must grasp hundreds of latest phrases. Different advanced fields, akin to regulation, finance and drugs, aren’t any completely different.
Information engineering shouldn’t be a brand new concept — library scientists and linguists repeatedly apply it. The creators of the “Longman Dictionary of Modern English,” for instance, engineered it in a approach that over 70,000 phrases may be outlined utilizing a core vocabulary of solely 2,000 phrases.
Books are linear whereas data shouldn’t be. Mapping of relationships throughout vastly completely different subjects 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 take a look at of this method, a group led by SRI Worldwide authored a number of chapters of a biology guide. The ensuing “clever textbook” was examined in a pilot examine. SRI reported that the common homework and take a look at scores of scholars utilizing the clever textbook have been 10 p.c larger than these of scholars utilizing the common textbook.
Comparable outcomes have been noticed in a monthlong classroom trial of the clever textbook led by Lena Tibell of Linköping College. Through 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 data engineering for an info retrieval textbook.
Information engineering additionally allows us to create concept-checkers for textbook authors which might be extra highly effective than spell-checkers. For instance, an writer can ask the questions: Have any ideas or capabilities been unnoticed of the textbook? Are any idea definitions inconsistent? This type of assist is unimaginable utilizing present authoring instruments.

Nevertheless, creating such textbooks won’t be cheap. Additionally it is not all the time potential to present a logical definition for each idea in a textbook.
Our means to present logical definitions typically ends on the boundary of present data. Reaching these boundaries can be utilized to immediate surprise 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 want a sustained effort to overtake the authoring of textbooks utilizing data engineering. For optimum near-term influence, we must always start with textbooks for gateway programs akin to biology and psychology.
We should practice and nurture a brand new career of data curators for curricular assets to allow this transformation.
Most significantly, the textbooks of the longer term should proceed to protect and talk the data of the most effective educators of our technology much more precisely and exactly than earlier than. Such textbooks, utilizing the self-discipline of data engineering, can assist the curation, preservation and studying of all types of human data.
