Abstract

The "2006 Survey of Introductory Astronomy Textbooks" had some inconsistencies and incompleteness inthe tables for ancillary and supplementary materials. This update includes revision of those tables plusupdated entries for 10 of the two dozen textbooks surveyed.

1. INTRODUCTION

To help instructors select textbooks for introductory astronomy courses, I have produced a series ofsurveys since 1997, with the latest appearing in this journal (Bruning 2006). My intention was to continuethis survey on a biennial basis, but the last installment had some inconsistencies and incompleteness in thetables describing ancillary and supplementary materials available for each text. This update should correctthose entries, as well as provide updates on 10 texts.

Rather than provide updated material for selected tables, I have updated the entire survey, except for thetable of alternative texts (e.g., Life in the Universe, Astronomy for Dummies). Two new titles have beenadded since the last survey, but two books have been discontinued, maintaining the number of texts at 23.Although a few teams have multiple versions of their texts, 18 different teams continue to write, enablingus to have a variety of voices and styles.

The titles included in this survey are (in alphabetical order by first author):

Arny--Explorations: An Introduction to AstronomyBennett, Donahue, Schneider, and Voit--The Cosmic PerspectiveBennett, Donahue, Schneider, and Voit--The Essential Cosmic PerspectiveBless--Discovering the Cosmos

Chaisson and McMillan--Astronomy: A Beginner’s Guide to the UniverseChaisson and McMillan--Astronomy TodayComins--Discovering the Essential UniverseComins and Kaufmann--Discovering the UniverseFix--Astronomy: Journey to the Cosmic FrontierFraknoi, Morrison, and Wolff--Voyages through the UniverseFreedman and Kaufmann--UniverseHester et al.--21st Century AstronomyKaler--Astronomy! A Brief EditionKuhn and Koupelis--In Quest of the UniversePasachoff--Astronomy: From Earth to the UniversePasachoff and Filippenko--The Cosmos: Astronomy in the New MillenniumSchneider and Arny--Pathways to AstronomySeeds--Astronomy: The Solar System and BeyondSeeds--Foundations of AstronomySeeds--Horizons: Exploring the UniverseSeeds and Backman--Perspectives on Astronomy*Shawl, Ashman, and Hufnagel--Discovering AstronomyZeilik--Astronomy: The Evolving Universe

* A current edition of this book was not received in time for the survey.

New editions of the following texts should be in print soon, but their publication date prevented them frombeing included in this survey:

Freedman and Kaufmann--Universe (8e)Kuhn and Koupelis--In Quest of the Universe (5e) Seeds--Horizons: Exploring the Universe (10e)

2. THE TEXTBOOK SURVEY

Information about the texts is contained in 12 tables. The tables list the texts in alphabetical order by title.Many readers refer to the books by author, so the list above provides a concordance.

A physical examination of each text provided the information contained in Tables 1–6. Information aboutancillaries and supplementary materials was obtained from a variety of sources, and we requested thateach publisher check the tables for their titles. Information about splits (text broken into two parts: "SolarSystem" and "Stars and Galaxies") came from inspection of the actual books.

The survey information is presented in twelve tables with entries collated by title. The tables contain:

1) Publisher and physical information

Title, author, pages, ISBN, price Pages are for running text only and do not include preface and appendices Price is publisher’s "list" price

2) Splits (text broken into two parts)

Title, author, pages, ISBN, price

2b) Splits (chapter counts and listing of repeated chapters)

3) Page counts by topic (percentages may not total 100%)

4) Appendixes

Glossary, star lists, planet data, star charts, and so on

5) Pedagogical features (Part I)

Learning objectives, summaries, questions, problems, reading list, activities

6) Pedagogical features (Part II)

Sidebars, essays, math level, other features

7) Ancillaries

CD-ROMs, transparencies, slides, test banks, instructor manuals, study guides, and so on

8) Supplements

PowerPoint materials, personal response systems, online quizzes and tests, WebCT or Blackboardfiles, electronic books, and other resources

9) Packages (sometimes called bundles; other books or materials that may be packaged with the text)

10) Text Web site URLs (see comment after this list)

11) Publisher Web site URLs (also includes links to astronomy textbook catalogs)

Text Web sites may be intended for use by the student, instructor or both; sometimes only one "flavor" isavailable, whereas other texts have multiple Web sites. Note that some publishers allow Web accessthrough a "quick link" using the author’s name. Several publishers maintain sites for previous editions oftexts. No attempt was made to describe the companion Web sites for the textbooks.

Repeated in this survey are author comments with updates and revisions. Although not every author teamresponded to the request for comments, users of this survey have responded favorably to their inclusion,and I encourage authors to respond in future surveys.

3. ANALYSIS

Average book size has not changed significantly from the last survey (now 604 vs. 602 pages), althoughseveral individual texts increased by 50–100 pages. Prices have increased slightly, from an average of$97.30 in 2006 to $99.28 in this survey (2%), but note that several books have increased in price by up to12%, outstripping inflation significantly.

Prices listed in this survey reflect publisher list prices, excluding discount prices at publisher Web sites.Your bookstore’s price may vary from the list prices stated in Table 1 owing to mark-ups, price changes,and book availability. Check with your local bookstore or bookseller to determine what their price to thestudent will be, if price is a final determinant in choosing between texts.

What is an average text like? It has 604 pages, has a soft cover, and starts with the Solar System and worksout to the universe as a whole (only three books order the topics the other way). Twenty-eight percent ofthe text is devoted to the Solar System (171 pages), 25% to stars (150 pages), 19% to galaxies andcosmology (117 pages), 15% to history and sky motions (93 pages), 9% to light and telescopes (52 pages),and 3% to astrobiology (18 pages). A few texts have additional chapters on modern physics. Texts average15 pages of appendixes, 15 glossary pages, and 15 pages of index. (These numbers may differ fromprevious editions because of a change in font size or other formatting changes.)

I am always interested in hearing from instructors regarding items that they would like to see included ormodified in this survey. The next installment of the text survey will return to its biennial appearance in 2009.

APPENDIX: AUTHOR COMMENTS

I wrote to each author team and asked them to respond in about 350 words to the questions below (seriesthat have splits or that include brief editions were only allowed one response).

1. What influenced you to write a text? 2. What pedagogical flavor have you tried to instill that makes your book different? 3. What do you think a student will understand differently about astronomy from your text? 4. What truly makes your text unique in your eyes? 5. What makes you most proud about your text?

Some authors responded directly to the questions, while others took a more free-form approach to describetheir text and writing. Not everyone chose to participate; the responses I received are included below inalphabetical order by text title.

Astronomy: From the Earth to the Universe (Jay Pasachoff)

1. What influenced you to write a text?

Just before I started teaching, I made a list for myself of the topics I wanted to emphasize, and Ifound no text that devoted a lot of space for them. The best text of the time started out with weeksand weeks of material that did not represent contemporary astronomy and that bored students beforegiving them the good stuff. I chose a textbook for first use, but I recorded my lectures in hope ofdoing better. It ultimately turned out that working from transcripts didn’t make sense, but I sat downand typed (yes, on a typewriter) a new book, Contemporary Astronomy, from scratch, with what Iviewed to be proper representation of both traditional and modern topics. That book had stars first,and when it was a runaway success, the publisher asked me to do a version with planets first, the firstedition of Astronomy: From the Earth to the Universe.

2. What pedagogical flavor have you tried to instill that makes your book different?

My book Astronomy: From the Earth to the Universe is organized as a set of stories. Each chapter isself-contained in a way that a professor can use it to organize a whole lecture. In each chapter, I firstset the scene with what was known for a long time, then describe more recent discoveries (for theplanets, with the first round of spacecraft for example), then describe what is being worked on now,and then tell what is expected in the future. I am proud that each planet has its own chapter and thatsuch important topics as black holes, quasars, and, most recently, exoplanets have their own chapters.This separation helps students keep the information clear in their minds. And the chapters are ontopics of special interest to students. At the same time, my inclusion of changing and importantcurrent research, and the latest and best illustrations, keeps the professors interested as well fromedition to edition. I have had some very long-term loyal adopters, to whom I am most grateful.

3. What do you think a student will understand differently about astronomy from your text?

I think students will come to understand how active today’s astronomy is and how it is far from amere set of facts. They should see how astronomers now tackle problems of astronomy and howcritical thinking and reasoning leads to our current understanding of the universe and of types ofobjects in it.

4. What truly makes your text unique, in your eyes?

I think my text is unique in the care and attention that I have paid to every aspect—every sentence,every drawing, every photograph, every updatable table or appendix—and the result that reflects theexperience I have in teaching the survey course every semester for a long time (leaves excepted). I alsothink it reflects the understanding I have gained over the years of not only teaching methods but also ofstudent learning. Further, my books incorporate knowledge about contemporary trends in astronomyteaching, reflecting my service on education committees including those of the American AstronomicalSociety, the American Physical Society, the American Association for the Advancement of Science, andof the American Association for the Advancement of Science, and, currently, as President of theInternational Astronomical Union’s Commission on Education and Development.

5. What makes you most proud about your text?

I am proud that I can incorporate the knowledge I have of research in many fields of astronomythrough my own studies of the sun, of x-radiation from stars, of planetary atmospheres, of interstellarmolecules, and of the cosmological results of nucleosynthesis studies, for example. My own studies withoptical and radio observatories on the ground and with telescopes in space give me experiences I havebeen able to share with students through discussions and features in my books. I am particularly proudhow I have been able to build on a solid base of traditional astronomy in presenting a current validframework of astronomy, properly giving students an idea of what astronomy is now. I am furtherparticularly proud of how I have been able to break down the reasoning relevant to various importanttopics in astronomy—such as why we think pulsars are rotating neutron stars or how spectral lines areformed—into steps, in both text and diagrams, that help student understanding. I am proud to haveproduced books that are colloquial and understandable at the same time that they are authoritative. And, ofcourse, I am very proud that so many astronomers and others teaching astronomy over so many years havefound my texts useful, authoritative, readable, and interesting.

The Cosmic Perspective and The Essential Cosmic Perspective (J. Bennett, M. Donahue, N. Schneider,and M. Voit)

There are many good textbooks out there, and I myself used several of them successfully in the past. Sowhy did I write my own? In brief, I hoped to improve on three particular things that gave my studentstrouble: First, the books were too jargon-heavy and difficult to understand; second, while many books dida good job on facts and details, they were weak on connecting to the "big picture"; third, I felt that thebooks tended to leave the all-important topic of how science is done to sidebars or occasional mentions,rather than making the nature of science an integral theme throughout the book. I believed it would bepossible to write a book that would give students both the big picture of our modern scientific view of theuniverse and a deep understanding of how science has allowed us to develop this big picture.

My opportunity to write arose after I completed a successful a mathematics text for the same audience ofnonscience majors; when my publisher realized I was an astronomer (rather than a mathematician), theyoffered me the chance to write an astronomy text. Knowing that astronomy is too large a field for oneperson to cover well, I recruited as co-authors three good friends whose expertise spans planetary science,stellar and galactic evolution, and cosmology. Together, we set out to write a book that would: (1)accomplish my goals with respect to the big picture and the nature of science; (2) be fully modern inreflecting the latest research; and (3) adhere to time-honored principles of effective teaching.

If you are unfamiliar with our texts, I encourage you to read our Prefaces, in which we lay out in moredetail the themes and pedagogical principles around which we’ve built our books. I also hope you’llexplore our web site, MasteringAstronomy.com, for which we authors have worked to ensure that thecontent ties directly to our book pedagogy. Finally, I invite you to e-mail me at any time ([email protected]) with your textbook questions, comments, or concerns.

The Cosmos: Astronomy in the New Millennium (J. Pasachoff and A. Filippenko)

1. What influenced you to write a text?

One of us (J. Pasachoff) was originally influenced to write a text when he found that none of the thencurrent texts met his teaching priorities, which included an emphasis on the progress of contemporaryastronomy and on the fact that the original standard topics, which should still be taught, were decadesor centuries old while students and faculty are interested in what is going on now. The other of us (A.Filippenko) used a prior version of the book for years in his very popular courses at Berkeley and,when asked, agreed to join in the project to help make the book relevant and exciting for the 21st century.

2. What pedagogical flavor have you tried to instill that makes your book different?

As active research astronomers, we have tried to provide personal examples of how we carry outastronomy today, and to provide our evaluation on the relative importance of various topics inmodern astronomy. In addition to the discussions of both standard and contemporary astronomicaltopics, we have special features "A Closer Look" and "Figure It Out" that allow professors to assigndeeper considerations of various topics. The interviews with several individual astronomers give alook at a diverse group of individuals who are working at the forefront.

We are also glad to have a new edition (which came out in February 2006) with coverage of so manyexciting astronomical events, such as the discovery of a Pluto-like object twice as far away, the crashof a spacecraft into a comet, the Huygens landing on Titan, and the discovery and analysis of newsupernovae, as well as updated images from Hubble, Chandra, and Spitzer.

3. What do you think a student will understand differently about astronomy from your text?

With one of us working on the forefront of supernova research and the discovery that the universe’sexpansion is accelerating, and the other working on a variety of solar, planetary, and x-ray topics, wehope that our excitement comes through.

4. What truly makes your text unique in your eyes?

The perspective of two active research scientists who are also involved in pedagogy (Pasachoff asPresident of the International Astronomical Union’s Commission on Education and Development andFilippenko as recent President of the Astronomical Society of the Pacific), as well as carefulsurveying and taking account of student experiences in the classes taught by the two over many years,has honed this text to excellent shape.

5. What makes you most proud about your text?

We are proud that we can bring so many topics of astronomy, both standard and contemporary,before students in an accurate, readable, and exciting way, beautifully and clearly illustrated throughout.We are proud to show students about priorities by, for example, having a separate chapter on the newplanets that are being discovered around other stars and, for a longer time, about black holes.

Discovering Astronomy (S. Shawl, K. Ashman, and B. Hufnagel)

The book was originally written to integrate into the textbook meaningful observational activities for usein a large lecture course and to emphasize active learning. The in-text questions causing students to slowdown and to think about the material was a new concept now duplicated by some others. The current leadauthor, brought in at the 3rd edition, became part of this project because he realized the approach of thebook was unique and was the best way to teach introductory astronomy. The opportunity to be involved insuch a book, and to help make it a mainstream book, was an opportunity that was seen as exciting,valuable, and worth doing.

The main flavor is active involvement by the reader, which is accomplished through "inquiries"(in-chapter questions asking the student to think about what was just read, or to predict, on the basis ofprevious reading and knowledge, something that is coming next [and answered in the coming subsection])."Discoveries" at the end of some chapters are relatively short activities; some use mathematics and aregood summaries of material discussed in the chapter. Although the separate Activities Manual is no longeran integral part of the text, users can make arrangements with the first author to obtain it for their classes.Thus, the original intent of integrating observing activities into a lecture course is still present for thosewho want their students to have such an experience.

A major theme of the book is the nature of science, which is why chapter 2 is a chapter on science andpseudoscience. The theme is carried throughout the book to provide students with an understanding ofwhat science is, what science is not, and what is not science.

Discovering Astronomy is unique in its emphasis on the nature of science and active learning. It was thefirst major textbook to approach the planets with a comparative planetology approach to the student of theplanets.

The authors feel their book presents the excitement of astronomy in an approachable way. We areconvinced that active involvement is the best way to help students learn. We are convinced that the mostimportant knowledge students can take from an introductory course is not the astronomy per se but anunderstanding of the nature of science, which we have worked hard to promote in our book.

Discovering the Universe (Neil Comins)

I had an epiphany one day while lecturing in introductory astronomy: what students hear in lecture andread in their textbooks frequently contradicts what they believe to be logically true. I researched andexperimented until I found ways of overcoming that problem in my teaching, namely to wake students upto their incorrect beliefs and so they’d be more receptive to the scientific explanation. When I started tosee the success of this in my classroom, the natural next step was to want to put some of these ideas into a textbook.

My goal is to make the student an active participant in the reading process. I ask questions designed to getstudents to think about their prior beliefs (both correct and incorrect) at the beginning of each chapter. Iflag the sections where the question is answered within the chapter, and then conclude the chapter withsummaries of the correct answers.

My hopes are that students will realize: that science is both an evolving body of knowledge as well as aprocess of discovery and understanding; that science has explanations for many things that the studentsdidn’t realize could be explained rationally; [and] the wide variety of things that astronomers understandabout the cosmos, how these things are related to each other and to our existence, and that they, thestudents, can understand this material, too. I also want them to see the beauty of the things in the universe.

If I had to choose one thing, it would be that the book is written at a level where students feel that they arelearning a lot, but don’t feel that they are being "talked down" to or pushed to understand information thatthey perceive as "over their heads."

Two related things make me most proud of the book: Student feedback includes comments like, "this isthe only textbook I kept after college"; and many of our peers around the world adopt it and keep using itand subsequent editions.

Foundations of Astronomy (Michael Seeds)

I began teaching astronomy in 1970 and quickly became unhappy with the books available. I didn’t wantto teach facts for students to memorize. I began writing my own text in 1977, and I focused on two goalsthat can be summarized as two questions: What are we? How do we know? The first question asks howhuman existence fits into the origin and evolution of the universe, and culminates in helping the studentsunderstand that their existence on the surface of a world is the product of billions of years of starbirth andstardeath. The atoms in our bodies were made in the big bang, cooked in stars, captured in the solar nebulaand now we are using them. That is a deep understanding of human existence that everyone should have.Only astronomy teaches it.

The second of my two questions is about science. When I say, "How do we know?" I mean "How doesscience work?" It is critical for students to understand that science is not belief or policy—it isunderstanding based on evidence. I have written every one of my books with the ideal of showing studentshow astronomers use evidence to understand our role in the universe. Books of facts can’t show studentshow wonderful our universe is. They must understand the logic instead of memorizing the facts, and thatmeans their book must present astronomy in the form of scientific arguments based on evidence.

As I began, I realized that writing a book based on evidence and scientific arguments meant I should keepthe solar system for last. Students could not understand what the solar system was until they had learnedabout the big bang, galaxies, stars, and stellar evolution. Otherwise they would be memorizing planetfacts. That stars-first order is my favorite way of teaching astronomy because it puts the solar system into perspective.

The key to teaching astronomy is perspective. We need to give students perspective on their role in theuniverse as tiny but highly gifted creatures trying to understand what we are.

21st Century Astronomy (J. Hester, D. Burstein, G. Blumenthal, R. Greeley, B. Smith, and H. Voss)

We are six authors whose collective professional experience covers the wide range of expertise needed inmodern astronomical research, including the solar system, the interstellar medium, stellar formation andevolution, the nature of galaxies, and cosmology. One author with more than 40 years of experience inteaching basic physics provides close watch over our pedagogical approach. Our writing style is lessformal than that found in most textbooks. As such, we allow ourselves to be conversational, sometimesprovocative, and occasionally irreverent. Our philosophical approach is to emphasize concepts rather thanrote facts, learning as opposed to memorization. Students are taught that all knowledge is provisional andthat in science we never prove things to be true; we only fail to show them to be false.

We have chosen an organization that is less traditional in favor of one that more accurately reflects theway astronomers think and work today. Rather than walk our way through the solar system in thetraditional manner, we organize the solar system section around the theme of comparative planetology.We discuss the formation of our solar system before discussing the planets themselves, allowing us to lookat planets within the context of how they were formed. Gravity is introduced early in the text, but we pullits more complex effects such as tidal interactions, orbital resonance, chaos, and similar phenomena into aseparate chapter that comes later when it is needed. The subject of origins is a recurring theme that runsthroughout the chapters, because the understanding of our origins embraces cosmology, stellar evolution,planetary atmospheres, geology, and biology.

Astronomy is one of the more rapidly advancing fields in modern science, and we owe it to the student toinclude the latest discoveries, interpretations, and definitions. In revising our second edition, we struggledwith the contentious decision by the IAU regarding Pluto and dwarf planets, realizing that manyastronomers strongly disagree with the IAU resolution. In the end we decided to treat the "classical" anddwarf planets exactly as the IAU had defined them, leaving it to the instructor to draw the student into the debate.

Voyages through the Universe (A. Fraknoi, D. Morrison, and S. Wolff)

When George Abell passed away suddenly, David Morrison and Sidney Wolff were asked to continue theline of textbook that he had started. After a number of years of updating the books, we asked AndrewFraknoi to join the team because of his teaching experience. Rather than revise and amend, our teamdecided to take a fresh look at making a modern textbook for non-science majors, and the Voyages serieswas born. Our philosophy is to take advantage of the distinct expertise of the three authors (the solarsystem for Morrison, stars and galaxies for Wolff, and education for Fraknoi) to write a book that isauthoritative and up to date, but selective in the material it presents. We want to offer a coherent "bigpicture" of what we know about the evolution of the universe, of galaxies, of stars, of planets, and of life,while making the book readable and accessible through the use of pedagogical tools and a careful choiceof illustrations. We focus on the ideas that matter in a form that makes sense.

We generally try to have less jargon and fewer disconnected factoids, but instead to tell the story ofmodern astronomical exploration in everyday language and with analogies drawn from the students’ ownexperiences. The books are written with a distinctive voice and a sense of humor (heaven knows,instructors and students can both use one.)

Some of the tools that we have incorporated into the books include
