Bienvenidos! Here we offer information and materials on using original historical sources in teaching mathematics. This includes our own experiences and materials, and those of others who are teaching with original sources. We welcome suggestions for other links to include here, and comments and suggestions for improvements.

Below we provide information on:

- Our own odyssey on teaching with original sources.
- Our lower division course and first book: Mathematical Expeditions: Chronicles by the Explorers.
- Our upper division
course and second book:
Mathematical
Masterpieces:
Further Chronicles by the Explorers (coathored with Arthur Knoebel and Jerry Lodder).

- Our graduate course on The Role of History in Teaching Mathematics.
- Our student projects for Teaching Discrete Mathematics and Computer Science (and More!) via Primary Historical Sources.
- Our articles on and about history of mathematics and its role in teaching.
- Other resources and inspiration for teaching with original sources and using history in teaching mathematics.

Our journey towards utilizing original texts as the primary
object of study in undergraduate and graduate courses began at
the senior undergraduate level. In 1987 we read
William Dunham's article *A "Great Theorems" Course in
Mathematics *(*American Mathematical Monthly* **93**
(1986), 808-811), in which he describes a course based on
mathematical masterpieces from the past, viewed as works of
art. His ideas and materials went on to become the well
known best-seller *Journey Through Genius: Great Theorems of
Mathematics.* We were inspired to develop a similar
course, at the senior level, but with one crucial difference:
Whereas Dunham presents his students with his own modern rendition
of these masterpieces, our idea was to use the original texts
themselves. With assistance from New Mexico State
University's honors program, dean, and mathematics department, we
developed and team taught the course *Great
Theorems: The Art of Mathematics*, and it has now
found a successful and permanent niche in the university's
curriculum, serving as a lively capstone course for students
majoring in a number of diverse disciplines. It is the only
mathematics course certified to meet the university's "Viewing a
Wider World" upper division general education requirement. Our
experiences with this senior level course convinced us that
teaching with original sources could be both successful and
inspiring for us and our students. The course is described
in detail in Mathematical
Masterpieces: Teaching With Original Sources (html)
(or dvi
or ps) (in *Vita Mathematica:
Historical Research and Integration with Teaching*, R.
Calinger (ed.), MAA, Washington, 1996, pp. 257-260). We also
involved other faculty in teaching and contributing material for
this course. Our four author second book
Mathematical
Masterpieces: Chronicles by the Explorers has emerged
from this course, written with two of these colleagues at New
Mexico State University, Arthur Knoebel and Jerry Lodder.

We came to believe that this approach to teaching and learning
could also help provide the motivation, perspective, and overview
so lacking in typical lower division courses, since it is being
increasingly recognized that an historical point of view can
address these deficiencies. As Niels Henrik Abel observed: "**It appears to me that if one wants to make
progress in mathematics, one should study the masters and not
the pupils.**" We have written an article Recovering Motivation in Mathematics: Teaching
with Original Sources (html) (or dvi
or ps) (*UME Trends ***6**,
September 1994) espousing our reasons and philosophy for this
teaching approach. We were inspired to try to use the study
of original texts as a teaching pedagogy introducing lower
division students to important currents of mathematical thought.

Thus we developed the course *Spirit and
Evolution of Mathematics*, again with support from
the New Mexico State University mathematics department and honors
program, allowing us to team teach the course while under
development. It provides an "introduction to great problems
of mathematics" for students with a good high school background in
mathematics, and is intended both to attract and retain
mathematics majors, and to give non majors a rich experience in
the nature and content of mathematical thought, satisfying a lower
division university mathematics general education requirement (the
course is one of only a handful certified for this). In
fact, the true prerequisite is a certain level of mathematical
maturity and ability, rather than courses with specific
content. Thus, a much broader audience has access to an
interesting course with serious mathematical content. Our
experiences, after teaching this course numerous times, have shown
that with careful selection of original texts, supplemental prose
readings, and appropriate format for classroom activities and
assignments, this approach can be a tremendous success.
Students find the study of original sources fascinating,
especially when combined with prose readings supplying cultural
and historical context, giving the course something of an
interdisciplinary flavor. The benefits for instructors and
students alike are a deepened appreciation for the origins and
nature of modern mathematics, as well as the lively and
stimulating class discussions engendered by the interpretation of
original sources. The course is described in detail in our
article Great Problems of
Mathematics: A Course Based on Original Sources (html) (or dvi or ps) (*American
Mathematical Monthly* **99** (1992), 313-317). Our first book Mathematical
Expeditions: Chronicles by the Explorers grew out of this course.

Since then we have expanded the use of original sources into high
school courses as well as graduate courses. Work with high
school students during two summer workshops at Colorado College
with Mike Siddoway is described in Great Problems of Mathematics:
A Workshop for High School Students (html) (or dvi or ps)
(*College Mathematics Journal* **25** (1994),
112-114). We also conducted a graduate course at New Mexico
State University for high school teachers on using original
sources in the high school curriculum. Our graduate students
showed great interest in this, and it has evolved into a regular
graduate course The
Role of History in Teaching Mathematics, providing part
of a growing mathematics education component in the mathematics graduate program
at New Mexico State University. The paper A graduate course on the role
of history in teaching mathematics describes the course and
its origins. The course syllabus
considers the use of history, in particular original sources,
throughout the mathematics curriculum. Our graduate students in
this course develop and critique
major teaching units based on history, often on original sources,
and we now have quite a collection of the historical
teaching modules they have written. A number of these have
been tested in the classroom. Their level ranges from middle
school through the advanced undergraduate curriculum. Write to us
if you want copies of any of these. Our long-term dream is that
the entire mathematics curriculum should be historically based,
with original sources playing a role throughout, and we ourselves
are endeavoring to incorporate both history and original sources
into all the courses we teach.

More recently David has teamed up with other colleagues from mathematics and computer science in applying our approach to the teaching of discrete mathematics, broadly conceived. We are combining the pedagogy of student projects (introduced into our calculus classes years ago) with the pedagogy of using original historical sources, in a NSF-funded program to develop and test student projects written using primary sources for teaching discrete mathematics.

Teaching with historical sources has also led us to several research projects in the history of mathematics, as shown in our articles listed below.

Mathematical Expeditions: Chronicles by the Explorers

Our first book of annotated original sources

The cover features portraits of five mathematicians whose original writings are at the heart of our five chapters, overlain with Sophie Germain's handwriting from a letter she wrote to Gauss in May of 1819 on her work on Fermat's Last Theorem, also featured in the book. See if you can read what Germain wrote to Gauss, or identify the people in the portraits. The book includes translations of Germain's letter and manuscripts, and ninety-four portraits, mosaics, artwork, facsimiles of handwritten manuscripts and letters, and figures.

From the back cover

*This book contains the stories of five mathematical journeys
into new realms, told through the writings of the explorers
themselves. Some were guided* *by mere
curiosity and the thrill of adventure, while others had more
practical motives. In each case the outcome was a vast
expansion of the known mathematical world and the realization
that still greater vistas remained to be explored. The
authors tell these stories by guiding the reader through the
very words of the mathematicians at the heart of these events,
and thereby provide insight into the art of approaching
mathematical problems.*

*The book can be used in a variety of ways. The five
chapters are completely independent, each with varying levels of
mathematical sophistication. The book will be enticing to
students, to instructors, and to the intellectually curious
reader. By working through some of the original sources
and supplemental exercises, which discuss and solve -- or
attempt to solve -- a great problem, this book helps the reader
discover the roots of modern problems, ideas, and concepts, even
whole subjects. Students will also see the obstacles that
earlier thinkers had to clear in order to make their respective
contributions to five central themes in the evolution of
mathematics.*

Together with our colleagues Arthur
Knoebel and Jerry Lodder,
and with further support from the National Science Foundation, we
have written an elder sibling for Mathematical
Expeditions. The new book Mathematical Masterpieces contains annotated original sources from our upper division
course *Great Theorems: The Art of
Mathematics*, presented as a capstone for the
undergraduate mathematics curriculum. The book is available
now from Springer, in
hardcover or paperback, in their Undergraduate Texts in
Mathematics/Readings in Mathematics series.

The cover features portraits of mathematicians whose original writings are at the heart of our four chapters. See if you can identify the people in the portraits. The cover also shows a figure by Huygens from the construction of an evolute in his Horologium Oscillatorium (The Pendulum Clock), in our chapter on the development of the concept of curvature. And we display Chinese text by Qin Jiu-Shao on approximating roots of polynomials, from our chapter on numerical solutions of equations. The book has many portraits, artwork, facsimiles of original works, and figures.

From the back cover

Experience the
discovery of mathematics by reading the original work of some
of the greatest minds throughout history. Here are
the stories of four mathematical adventures, including the
Bernoulli numbers as the passage between discrete and
continuous phenomena, the search for numerical solutions to
equations throughout time, the discovery of curvature and
geometric space, and the quest for patterns in prime numbers.
Each story is told through the words of the pioneers of
mathematical thought. Particular advantages of the historical
approach include providing context to mathematical inquiry,
perspective to proposed conceptual solutions, and a glimpse into
the direction research has taken. The text is ideal for
an undergraduate seminar, independent reading, or a capstone
course, and offers a wealth of student exercises with
a prerequisite of at most multivariable calculus.

**Mathematical Masterpieces

Mathematical Masterpieces has been reviewed by the Mathematical Association of America.

Here you can read the book's preface (which discusses teaching
uses for the book), the table of contents, and the chapter
introductions and some sample sections of the book. The article The bridge between the continuous and the
discrete via original sources describes one of the chapters,
and the article Curvature
in
the Calculus Curriculum discusses how source material from
our curvature chapter has been used in teaching calculus.

Teaching Discrete Mathematics and Computer Science (and now More!) via Primary Historical Sources

David is part of a team of mathematicians and computer scientists
at this and other universities, who are applying this approach to
the teaching of discrete mathematics (and now more!), broadly
conceived. We are melding the pedagogy of teaching with student
projects (introduced into our
calculus
classes years ago) with the pedagogy of using original
historical sources, in NSF-funded programs to develop, test,
evaluate, and disseminate student projects written using primary
historical sources for courses in discrete mathematics,
combinatorics, abstract algebra, logic, and algorithmic thought in
computer science (and now even more!). See our web pages Teaching
Discrete Mathematics via Primary Historical Sources
for the pedagogy and results of our Phase I NSF pilot
grant, including the classroom projects developed and published
under that grant through year 2006. See our web pages Learning
Discrete Mathematics and Computer Science via Primary Historical
Sources for the work commencing in year 2008 under our Phase
II NSF expansion grant, including the many new projects created
under that grant. And see the pages Transforming
Instruction in Undergraduate Mathematics via Primary Historical
Sources (TRIUMPHS) for continuing work commencing in 2015 to
develop primary source projects (PSPs) and mini-PSPs for the
content of all regular courses for mathematics majors, pre-service
teachers, and other STEM discipline majors. We have taught courses in
discrete mathematics, combinatorics, mathematical logic, and
number theory entirely from our PSPs and other primary sources,
obviating any need for a textbook. We welcome those who would like
to use or test our student projects.
