This is often a matter of opinion across Biology professors, so that is not surprising. The content is changed very frequently- my one concern would be if these changes were major, how would that influence the ease-of-use for those students that download and print or order a text copy? All Right Reserved. This book will serve the purpose of introductory biology and could very well be used in place of the expensive textbooks. On page 90, the text states, Being the outermost structure in animal cells, the plasma membrane is responsible for the transport of materials and cellular recognition and it is involved in cell-to-cell communication. Why only animal cells? Indexes and glossaries are good, which is important because definitions are often not given in the text. Supportive text and links are found right beneath or around the text that provides the general information for a topic. At the end of each chapter, there is a glossary of key terms, chapter summaries (divided by section), visual connection questions, multiple-choice review questions, and short-answer critical thinking questions. However, the blanket statement as written by the authors instead plays to the very common misconception that genes are all-powerful and determine ones fate. I realize that it is impossible to provide this quality of artwork in an open source textbook, but I think it is also important to recognize how important such features are for students attempting to visualize complex structures and to master difficult concepts. The additional content of animations was well done and accessible. This is well done. Further, labeling of figure components is often too small and borderline blurry. For my own satisfaction- I would have liked to see the citations but lack of it does not make the book any less effective. The only issue is that the chapter numbers and pages differ between the pdf and the read online versions. For the most part the concepts and topics are up-to-date. Content is consistent with any basic entrance level Biology course. In Chapter 3, the Evolution Connection on cytochrome C is not well explained: When human and rhesus monkey sequences were compared, the single difference found was in one amino acid. I found that the level of detail is appropriate for a lower level undergraduate biology course. Due to the nature of a general biology course, there are certainly chapters that should be covered before other chapters. The topics are arranged in a typically progression and build on one another in a traditional fashion. read more. A few are important to correct, especially given that we push students to understand the need for precise use of science terminology and vocabulary (e.g., Section 34.2 is titled "Nutrition and Energy Production," which might confuse a student who has learned that "energy can neither be created nor destroyed."). Next generation sequencing is the topic of only one VERY short paragraph in chapter 17 as far as I found. A compressed-air cylinder stands 100cm100 \mathrm{~cm}100cm tall and has internal diameter 20.0cm20.0 \mathrm{~cm}20.0cm. The index has links to the relevant sections, which is helpful, and each chapter contains a Key Words section. citation tool such as, Authors: Mary Ann Clark, Matthew Douglas, Jung Choi. Each chapter also includes a list of key terms basically, a mini-glossary at the end just before the chapter summary. I found no grammatical errors, nor did I find distracting terms. Systematics could be another trouble spot, but the authors do OK presenting an up-to-date, albeit conservative phylogeny. to "large-scale" scale Biology (evolution, ecology, etc.). How do they homeostatically maintain the near neutral pH inside them? For the level of students being targeted, there is sufficient focus. Please see also my comments below under the prompt about cultural relevance. I would definitely consider adopting this textbook for a non-majors introductory class at the freshman level. The figures are far less polished than those found in traditional textbooks, reducing clarity somewhat. There is no discussion of hypotheses that cannot be directly tested by controlled experiment, for ethical reasons or reasons of temporal or spatial scale. Although this book had 6 Senior Contributors and a large number of Faculty Contributors, the editing was done in a manner that kept the framework and terminology consistent throughout the book. I also did not find an easy way to highlight or make notes in the online version, which are features often available in commercial online texts. Also, some of these basic concepts are essential to build upon as the student reads through the text. stream Reviewed by Christy Fillman, Senior Instructor, CU Boulder on 7/1/19, I am writing this review of the genetics unit from Biology 2e (chapters 11-17) in the context of potentially using this book for an introductory level, one semester genetics course for majors. The questions that are offered for student review of what they've learned are generally shallow and do not offer much access to ways that a student might learn more about the topics. Most require that students explain or apply a concept from the textbook. At the level of details, I found a few places in the text in which terms were used before they were defined, though in such cases they were usually defined in the following paragraph/page. While some topics and visuals are redundant across chapters, this also helps with modularity of the text. 54 27 100 108 5. I thought the biotechnology chapter was particularly good, and better that my current textbook, which is not the most up to date, even in the newest edition. Students will have seen much of the necessary content in a year-long introductory sequence, but nonetheless will need reference and reminders on the chemistry of life (Ch 2), biological molecules (Ch 3), cell structure (Ch 4), and membrane function (Ch 5). The first forms of life on Earth were ________. You have saved me many hours of work. For example, in the photosynthesis chapter, the explanation of the light reactions is much more straightforward than in my book. The textbook explains very complex topics in a comprehensive manner and appears to be designed for early term biology and associated science majors. Sanger sequencing is described in chapter 14 as being widely used today (p. 385). On page 481, the text fails to explain why a mutation may be neutral. Biologists refer to this fit as adaptation, and it is a consequence of evolution by I did notice a minor inconsistency in taxonomy between the Cell section and the Diversity sections. Very evident in Cellular respiration chapter This text was written in a more straight-forward manner than my current text that I am using. In addition, students need to refer to some of the background on cell metabolism and cellular respiration (Ch 6 and Ch 7, respectively). This particular information is relatively new in the field of biology, though most of the current discoveries lie in the realm of gene function and would be included in an upper level course. I think visibility might be even more of an issue on a cell phone, which I know many students use to view their digital texts. There were very few grammatical errors. The links that I clicked to external sites all worked well. For instance different aspects regarding natural selection are found in three sections in two different chapters, being the sections: understanding evolution, population genetics, and adaptive evolution. They have provided the square for accessing videos, and also provide a link to videos, but sometimes the link to the videos is not available on a pc computer. I did not notice any bias towards or against historical studies, current topics, research, or ideas made apparent. Career Connections are great throughout, but some appear to be written from an American perspective. But an editor had to step in and work for consistency. Overall, I highly recommend the book. I have not encountered grammatical errors in the text. (a) element; (b) element; (c) compound; (d) mixture; (e) compound; (f) compound; (g) compound; (h) mixture. read more. P. 451 How can student get cDNA in one sentence? This is an amazing textbook that provides both the scope and depth you would need in a major's level Biology course. Much of the time, the text took on a more conversational tone than I was expecting, which I feel will appeal to readers. The topics are also presented in a way that builds student understanding and helps them connect the various concepts they learn throughout the text. Students should be able to build upon their knowledge and comprehension as they proceed through the course. It covers all the topics in sufficient detail for the student to succeed. (I use the phrases appear to be, light-skinned, and male-presenting because I do not presume to know how all the people in all the photographs identify.) The glossary appears comprehensive, however, many duplicates (ie. Reviewed by John Lepri, Professor (Biology), University of North Carolina at Greensboro on 12/5/16, Spanning 47 chapters, the OpenStax "Biology" production is as comprehensive as its competitors. The book is divided into topical subsections much like mainstream print books of its kind. The order of topics is also similar to other books and follows a logical progression: process of science, chemistry, cell biology, genetics, evolution, biological diversity, plant structure/function, animal structure/function, and ecology. Many of the links are to YouTube videos, some of which are embedded and play directly in the text, whereas others open in a new tab. Overall, the text is accurate. The book is very well organized, with all of the typical topics for non-majors biology classes present. The biggest issue, though, is the images. The answer guide available to verified instructors (verification is simple and takes about a day or two) is useful. Web resources have a notoriously short longevity and links to external sources need updating, so their inclusion makes regular updating essential if only for that reason. On the positive side, the section on global climate change is quite welcome as being highly relevant. I did not see any grammatical issues while skimming the text. The reviewers noticed that care was taken to include recent findings (for example, neurogenesis and BrdU labeling; epigenetics; personalized medicine).

Overall, I felt that the authors made wise choices in balancing clarity of illustrations against complexity of an illustration. It would be helpful for my objectives to have a stronger treatment of invertebrates. Have the text as both an online and pdf document is helpful because if student needed to increase the size of the image, they could always look at the other version. The book accurately covers different aspects of biology. On page 496, the explanation of punctuated equilibrium is very weak. I know that several other reviewers commented on errors they found in this textbook. In another example, 7.11 and 7.12 both refer to pH gradients across the mitochondrial membrane. Other The text appears to be very comprehensive. A well-organized textbook interface is provided. Reviewed by Joseph Ly, Lecturer, St. Ambrose University on 10/26/18, Is able to cover aspects of biology very well. Overall, This OER textbook is a well-designed biology textbook that gives a clear, consistent, and thorough presentation of the subject matter, so assisting students in developing a solid grasp of the concepts and principles of biology. In a few cases, I saw Hydrogen ions referred to as protons (and vice versa) without explaining that they were the same thing in the same chapter. Still, if you prefer to create your own lectures, this text is without a doubt a top choice. read more. Reviewed by Julia Mabry, Adjunct Faculty, Clatsop Community College on 12/18/20, I have used chapter 1-16 of this book for a 100-level community college class "Integrated Chemistry and Cellular Biology for Healthcare Professionals". The navigation is a bit easier with the downloaded version, as the online version is divided into units, so if you just give your student a chapter to look at, you may need to tell them which unit the chapter is listed under. Each chapter includes at least one link to an external resource. catalyst in a biochemical reaction that is usually a complex or conjugated protein. With a few exceptions, the textbook addresses relevant issues in biology while also presenting historical findings. For instance "anabolic pathways require an input of energy to synthesize complex.. is accurate. read more. I would say the authors play it safe and structure/organize the material in standard fashion (there is nothing revolutionary or new about the pedagogical approach it adopts): it reads like a very traditional print biology textbook. "Connection" sections (except for "Art") were for the most part excellent and bridged concepts with real-world issues. I think students will find it easy and straightforward to read. I believe this will allow for easy alignment into any new or existing Biology course. The book has links to external digital content at OpenStax but some of the QR codes and/or URL do not seem to function. I also like the frequent inclusion of the "Career Connection" items -- they're very accessible and our students need to know there are many, many careers in biology beyond healthcare, teaching, and academic research. I appreciate this because it allows for the cross-referencing of important cellular and genetic concepts in later chapters. 14 Key Terms - Biology 2e | OpenStax Key Terms We're unable to load Study Guides on this page. I would have liked to see more surrounding that topic in the way of images, and even information. While not in detail, most of the material covered gives the reader a basic understanding of various biological processes. Reviewed by David Carlini, Associate Professor, American University on 2/1/18, This text is very comprehensive, covering all topics that should be included in a two semester undergraduate introductory biology course for Biology majors/premedical students. End-of-chapter questions are included for students to check their understanding. I could not image how to part of a chapter to cover the basics of a topic. It doesn't work very well. WebCh. Reviewed by Petra Kranzfelder, Assistant Teaching Professor, University of California, Merced on 3/5/20, This textbook covers the typical introductory biology course topics for biology majors, including chemistry, cells, genetics, evolution, biodiversity, plant and animal form and function, and ecology. This text covers all subject matter used in a one semester introductory biology course. In other instances, particularly later chapters, clarity could be improved with more and/or improved visuals. The most distressing to me comes early, in the first chapter. Sample answer: Gatorade contains water, sugar, dextrose, citric acid, salt, sodium chloride, monopotassium phosphate, and sucrose acetate isobutyrate. The contents list expands readily, and the names of the chapters mirrors those in the competitor texts. the study of living organisms and their interactions with one another and their environments. For example, the section on global climate change could include information on rising sea levels and how island nations and their culture will be eliminated. From this perspective, I would have actually preferred if the text was less modular. Content-wise, Biology -2e very closely aligns itself with most traditional introductory Biology text books. On page 804, the text states, The notochord, however, is not found in the postnatal stage of vertebrates. On page 807, it says, In adult vertebrates, the vertebral column replaces the notochord, which is only seen in the embryonic stage. Not so! Figures and images are places between paragraphs. As a result of the modularity, if a different progression is preferred it is easy to select material in a manner that aligns with your course/preferences. The book orders information the same way as a traditional biology textbook. Colored images work better for the students since I emphasize that is publisher is paying more for the color it must be important. hypothesis variable theory control 6. Each chapter has a number of small photographs, Want to cite, share, or modify this book? The web based interface is simple and clean, and not overly complicated.

The chapter sections are well defined and accurately titled. The external link is no help because it uses a completely different scheme. The authors maintained a consistent style and flow throughout the book. This terminology is out-of-date and reinforces student misconceptions of evolutionary change as goal-directed and progressive. However, the answers are difficult to quickly locate as they are listed in paragraph format, rather than organized as a list. The chapters are clear and concise. I I focused in on Chapter 15: Genes and Proteins. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Some of the language is loose: "Need for osmoregulation" implies that osmoregulation happens because it needs to happen, instead of correctly stating that "osmoregulation happens" because of all the partnering proteins, the membranes, the solutes, the pumps, etc. The OpenStax Biology book has units and chapters that cover all of the major topics that one would consider for a general or introductory Biology course. The Biology 2e text is comprehensive without being overwhelming and provides a similar organization and logical flow as the previous text. read more. The online version has additional organizational features that connect glossary terms with each subsection, rather than an entire chapter or even at the end of the book. In fact, throughout the textbook, bacteria are mentioned in contexts where bacteria and archaea should both be included. ions neutrons neutral atoms isotopes 6. read more. Text modularity is good. Everything is formatted correctly and links and images are accessible on both devices. Modularity is good! While the artwork is generally good some of the illustrations are too small and generally not as visually appealing as in commercial textbooks. Ideally evolution should be covered right at the start in some level of detail to help students understand and connect the chapters before the evolution chapter; however overall the organization is good and flows well. My review of the text found no errors and it appeared in every since to follow the standard for a quality general biology text. I feel this book would be relevant for biology majors, learning their new field, as well as non-majors exploring the topic for the first and (maybe) only time. The unit and chapter breakdown was very well done and organized appropriately. The overall framework makes it easy for students to find what they are looking for and they are not constantly adapting to a changing layout. This book is a great free replacement for the textbook we normally use from a large name publisher. In Chapter 18, the text only includes the biological species concept, with no discussion of its weaknesses or limitations. The organization of the book is intuitive and I can easily find information and readings associated with class topics through the table of contents. The index at the end of the book and the glossary-key terms- at the end of each chapter are both very comprehensive as well. I'm also not clear if students would have access to the answers for the review questions as I couldn't find it.
