I compare the chapter from Biology 2e to both the first edition Openstax Biology and a traditional introductory text from a major publisher. a. how selective forces change the allele frequencies in a population over time However, the scientists who are mentioned are the typical examples theres no obvious effort to include or highlight contributions from a variety of cultures or ethnic backgrounds. Similarly, an instructor would need to be able to fill in more details and context for many of the topics by consulting other texts or teaching materials. R0Et|K1gk(XEM%vxy8M17. As my class has a focus on biotechnology, this will be the first time it is included in a 'general use' textbook. Something especially unique about this book is the Career connections Section within every chapter. For the level of students being targeted, there is sufficient focus. Different topics in the text are organized and presented in a logical manner that make sense from biological perspective. 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? On page 159, crenation does not mean shrinkage but refers to the effect of shrinkage on the cell membrane. 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. I did not notice grammatical errors but I was speed-reading. The level of depth of material is consistent enough as well that the information covered is "accurate" to the level required for the text book. The chapters are divided into topical sections, making it easy to assign or not assign specific topics. However, the answers are difficult to quickly locate as they are listed in paragraph format, rather than organized as a list. The book was published in 2013 and in spite of the 2017 Rice University copyright notice it does not appear to have been updated since the original publication. Generally, the book is written at a student's level. (Rosalind Franklin deserves a photo next to Crick and Watson.) I think students would also like this option. After chapter questions give a start to learning to take the assessment but various levels of blooms taxonomy questions can be added to promote / advance the critical thinking skills. Reviewed by Ken Carloni, Assoc. The textbook is written in a clear language, easy to understand by freshmen students. Smith, Michael Abbott. It is provides a baseline for the essential content for a Biology course. External supplementary links are provided and augment the text. Furthermore, for students who will only be taking one year of biology, I am confident that using this textbook will give them a broad overview of the field and introduce them to more specific topics that could help them in any major or career. The only issue is that the chapter numbers and pages differ between the pdf and the read online versions. Topics are explained in a clear and concise manner. A comprehensive index is provided at the end of the text. As mentioned, there are not long blocks of text that most units and chapters are divided into short, directly linkable chunks. Figure 3.32 is not helpful and does not show H-bonding or antiparallel arrangement clearly. ISBN. There were also many resources for both the instructor and the students that make the use of this book ideal. In some cases, these are not strictly related to biology; for example, quantitative and qualitative are discussed but not defined in Chapter 1. WebAnswers will vary. In the complement pathway, the lectin pathway is missing. read more. Learning outcomes are specified throughout and are clear and complete. The flow of the text as it begins at lower levels of biological organization and moves up to the highest levels follows a typical format of many introductory texts. There is not a glossary, which would be helpful, but new terms are generally in bold. While the authors/publisher did not create the video, they are responsible for it being embedded in the textbook. On the instructor side, anyone who relies on powerpoints, especially new instructors, would find the lack of included images to be challenging and the need to add images will raise some issues around using copyrighted material from other sources. You can even purchase a bound copy from Amazon for around $60, which is very reasonable for a textbook. At the end of the textbook, appendices (e.g., periodic table, metric system) and a comprehensive index are included. However, this reviewer feels that there are too few images/charts to explain concepts. Review Questions at End of Section These are relatively short and simple. 1 Review Questions - Biology 2e | OpenStax 4. I teach "Cell Biology for Health Occupations" at a community college, and we currently use an abridged version of Pearson's Campbell Biology in Focus textbook. A few typos, but not excessive for such a large text. It would be better to list these after a single entry for each term. There are few images of people in the text. I only viewed the text using a laptop, so I cannot comment on its interface on a smartphone or tablet. One unfortunate (in my mind) example is that a photo featuring Watson and Crick is present, yet there is no photo of Rosalind Franklin (though her name is mentioned in the text). This example most closely resembles which type of reasoning? There are a few things that pervade the text that I take issue with. The references to recent research areas is an asset. I also think that the links to external resources may be difficult to maintain, although I did spot-check those and the links were all good. There are some nuances of classification and speaking in generalities that could lead the learner to think in terms of absolutes where that may not be the case (ie. Aside from the figures, other aspects of the interface function well. Reading those sections alone would seem to reinforce memorization of the details rather than an understanding of the relevance process. read more. I thought many images had a random quality. Yes, this text is much like any of the regular, paper general biology textbooks. Because there is so much information to cover in the Introductory Biology survey courses, it is helpful to organize the text in this way so students are not overwhelmed. Finally, some chapters have abstracts and other chapter dont. The former links students to videos, animations, and primary literature while the latter highlights different careers that apply to the section discussed in the text. Book reads like an easy nonfiction science read. In fact, I would argue that a strength of digital textbooks is the ability to quickly zip from one section to another with a click. There are a few exceptions; for instance, the details about phospholipid structure are much more specific than I would require in an introductory class. Biology was very comprehensive in its covering of general biology topics and the "Link to Learning" feature allows the learner to expand the concept. The text is written in a clear and easy to comprehend manner. The diagrams of almost every human body system had outlines that suggested long, straight noses,, non-ethnic hair styles, and no disabilities (e.g., someone using a wheelchair). read more. Specifically stating which pages the specific answers could be found would be even better. Material is presented in an engaging way with practical examples that students can easily relate to. Images are detailed and appealing to the reader. I think the layout is consistent within this text. I think most reasonably flexible instructors would not find the organization to clash with the organization of their course. For these reasons, I think this would be a very difficult text for a new instructor to teach from. There are also chapter summaries and review sections at the end of every chapter. While not in detail, most of the material covered gives the reader a basic understanding of various biological processes. The illustrations while generally very appropriate perhaps could be shown larger and in more visually appealing ways (e.g. The importance of phylogeny, and the basic elements of phylogeny construction and interpretation are fairly well presented in Chapter 20, but they are sparsely employed in the remainder of the text. Here are a few errors that I noted: I am specifically looking for a text that I can supplement, not a text that covers everything as the forefront of science since science quickly changes and as an instructor, I enjoy finding new articles or resources for my students each semester to keep the course up-to-date and more interactive for the students (and me). Although alternative splicing is mentioned in Chapter 16, it should be described in Section 15.4. Students can download this text for free, view it on their devices and print it out. This is a great chance to show the accomplishments of a brilliant woman. Tunicates and vertebrates are sister taxa that diverged more recently. Glossary terms, chapter summaries, and chapter reading questions are a welcome study tool for students. The text covers essential content in sufficient detail for an introductory and/or non-majors biology survey type course. Students struggle with tree-thinking, a necessary skill for anyone who plans to continue in biology. (Fig 7.4 claims to show a phosphorylation reaction in which the third phosphate of ATP attaches to a protein. Jumping to the electron transport system is an odd way to start in 7.1. Overall, topics seem to flow nicely within individual chapters and also are appropriately ordered within the larger Units. storage carbohydrate in animals. The textbook also has an assortment of web links that will need to be maintained. The material is presented in a logical and consistent manner to facilitate effective learning and understanding. I found no problems with the accuracy of major concepts or with the more specific steps of cellular respiration. But, in the case of mitosis, the lack of a good figure of the mitotic spindle is notable. This textbook was comprehensively organized and populated with topics. The text includes examples of diverse organisms from around the world. Given that this is a text for two semester introductory sequence in biology for undergraduates, it appears to be very comprehensive. The book is organized in a very similar manner to most introductory Biology textbooks - with good reason. plants microorganisms birds dinosaurs 5. The text book uses accessible prose while at the same time expecting the student to remain current with the material learned in previous chapters. The sections on anatomy and physiology of the human body had a nice mix of explaining structures and functions, and linking these with disorders to make the content more relevant and interesting. Biodiversity chapter information (e.g., Table 28.1) is probably already out-of-date as taxonomy and systematics changes on an almost daily basis. In some instances, the language could be simplified to make the text more accessible and terms better defined. Chapter 7 was broken down into small, manageable sub-sections which could be easily assigned to students. It's hard to say how quickly these current examples will become obsolete, but this would be a problem with any textbook that uses current examples. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. This seems like a great book for freshman because often at that stage the students are interested in science but are unsure of what branch of science they want to go into. The significance of these comparisons is not explained. Biology is an extremely broad subject area to cover and the authors do a great job of covering topics as diverse as general chemistry to biodiversity conservation. Each For example, they use the term Citric Acid Cycle instead of the Krebs Cycle, and this is conserved throughout the text. Figures and images are places between paragraphs. I dont think this type of writing will attract any students to this type of text over a paper textbook. Reviewed by Jonathan Karpel, Associate Professor, Southern Utah U on 8/2/18, Yes, this text is much like any of the regular, paper general biology textbooks. As always when covering such a large amount of information in relatively selective detail, some topics will get more or less attention than an instructor may wish to cover in their own course, but the OER nature of the text makes it fairly customizable. There is no list of references at the end of each chapter to the literature. WebAnswer Both systems involve chemical messengers that must interact with receptors in order to have an effect. The placement of the chapter within the larger text makes sense, following a section on the introduction to metabolism, and preceding a section on photosynthesis. then you must include on every physical page the following attribution: If you are redistributing all or part of this book in a digital format, The authors maintained a consistent style and flow throughout the book. This is a very comprehensive textbook that provides an appropriate balance between the different fields of biology. (ID: 349a8a47e1d944c18f9bdae4af018fe7) electrophoresis technique used to separate DNA fragments according to size helicase Reviewed by Christopher Sorenson, Instructor, St. Each chapter begins with a list of learning objectives. This would necessitate a rewriting. All texts tend to emphasize some areas over others, and this is no exception. It is good to be able to search the documents easily because they are online. I personally do not find those to be too distracting since this book would be utilized in a beginning course, although I do feel they should be addressed to avoid misinformation. Perhaps the diverse and multi-author origin of the book's content ensured the excellence of the book in this regard. Similarly, if you seek to install the Tea Coffee Machines, you will not only get quality tested equipment, at a rate which you can afford, but you will also get a chosen assortment of coffee powders and tea bags. The text book is easy to navigate with essential and well chosen figures and links to outside resources, some very good and simple animations. In the sections of my review below, I discuss the information my students need in relation to the content of this text. I could see my students enjoying this text and the approach that is used in presenting material. Its the lignified schlerenchyma cells. However, in order to sustain student interest, it maybe useful to add a few more examples where biological concepts are applied to daily living making this subject more interesting to the reader. I appreciate the approach in using multiple, short chapters instead of fewer, longer chapters as I find students (particularly in non-majors) courses tend to get overwhelmed with longer reading assignments. This textbook did a great job of presenting seminal, historical research as well as using examples and illustrations from today to explain biological concepts and theories. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. Overall, this book provides what I need content-wise for my introductory courses. For example the authors point out the differences between T-helper cells such as TH1, Th2 and Regulatory T-cells. The book is quite comprehensive and covers all aspect of biology that one can choose from to cover in an introductory biology course. The descriptions explanations are well-written at an appropriate level for lower level biology and non-majors courses. I was disappointed that the vast majority of images were of white people. With the downloaded pdf or (I am assuming) the printed text version, the glossary comes at the end of the chapter. This book teaches them the basics every biology major should become familiar but spans a large amount of disciplines within biology. P. 451 How can student get cDNA in one sentence? Additionally, when describing the different types of RNA that can be found in a cell, not only does the text mention mRNA and tRNA, but additionally rRNA, which some introductory books leave out. Many topics are covered at a moderate level of depth with additional links provided to content from other sections of the text in the 'connections' sections. Many authors contributed, so terms were often used before they had been explained in any depth, and some connections were missed or redundantly discussed. I have adopted OpenStax Biology for my life science majors introductory course "Organismal and Ecological Biology. Chair, Umpqua Community College on 8/21/16, Content Depth: A- For additional free and open resources, visit http://www.openstax.org/. In some instances, I felt that certain topics, such as stem cell research, were not given much coverage, but the overall coverage was excellent. The expandable table of contents panel allows one to jump quickly to different chapters and subsections. Topics presented are organized in a logical manner with topics building on previous sections. Reviewed by Tobili Sam-Yellowe, Professor, Cleveland State University on 1/12/15, The text covers all areas of biology appropriate for first year biology students.

For example, the large aquatic reptiles of the Mesozoic Era were not in fact dinosaurs; they were just contemporaries of dinosaurs. glycosidic bond. Chapters 28 and 29 on invertebrates and vertebrates, respectively, provide an overview of the major phyla. This structure is also attractive to instructors as it allows us the freedom to pick and choose textbook content to assign. There could be more cultural references in the examples of careers sections. OpenStax Reading Guides. On a more negative note, a reference was made to "hard" and "soft" sciences with biology being called a "hard" or quantitative science which was identified as different from the more qualitative or "soft" social sciences. Reviewed by Karen Sirum, Associate Professor, Bowling Green State University on 2/1/18, Core concepts for introductory level college course are addressed in sufficient detail, without overly complicating the material for this audience. Reviewed by Dan Atwater, Assistant Professor, Earlham College on 6/23/19, The comprehensiveness varies but is overall mostly appropriate. read more. Graphics Second half an easily be taught out of order while keeping the integrity of the textbook order. Figures were also accurate and current. In Fig 3.12 "Hydrophobic lipids" is redundant. For new instructors, I would also feel like they would need an alternative textbook, at least for reference since this book has so much less depth on most topics. The topics are presented in a logical, clear fashion, with minimal searching for an area of interest. Some of the content, such as mitosis and meiosis, are separated into different chapters, which is different from some of the standard texts used (e.g. More recent genomic analysis has identified cephalochordates as the most basal chordates. The links are in the above post, as either google doc files or as pdf. The writing style is easy to read and is well written for the freshman/sophomore level. "Connection" sections (except for "Art") were for the most part excellent and bridged concepts with real-world issues. However, they are inconsistent in the quality of the website links. However, it still seems slightly dated even with this consideration. The areas with the most change are systematics and human ecology, and those are reasonably current. Only issues I've found are in the accuracy of illustrations -- several are mis-labeled. Consistency is good but not great. Chapters are broken down into easy-to-assign modules. Weballosteric inhibition. The themes are appropriate and comprehensive. Irrespective of the kind of premix that you invest in, you together with your guests will have a whale of a time enjoying refreshing cups of beverage. Its nice to have a free textbook from a reputable university that can give students from lower incomes the ability to have the same depth and breadth of information for no money on or before the first day. This seems like a great book for freshman because often at that stage the students are interested in science but are unsure of what branch of science they want to go into. Yes, this text is much like any of the regular, paper general biology textbooks. It covers all the topics in sufficient detail for the student to succeed. read more. I found them very densely written. Overall, the coverage of subjects is appropriate for an introductory majors-level textbook that would be used across two (or more) semesters. In a very few places this book might need to be updatedfor example, some of the taxonomic diversity of prokaryotic and eukaryotic groups, and some other statements (for example, there is a lot of life near deep sea vents that does not depend in any way on photosynthesis). For the most part, the content is up-to-date, but I did find a few sections that already needed updating. Complete the following page as thoroughly as possible. If you enter into a new tab, you can see the images better in some cases, but this may not be the case for those that print out the book. The open access nature of the content means that figures and illustrations are readily available online, making it easier for instructors to access the supporting content and incorporate it into their own teaching materials (the book also comes with all the standard instructor resources), and for students to directly interface with other online media (for example, embedded YouTube videos). read more. While some introductory biology students have a general career plan, many are unaware of the scope of what work in biology can be. Of the Career Connection vignettes that do have photographs, it appeared to me that all people shown were light skinned and only one was likely to be female-identified. The graphics are fewer and lower quality compared to expensive conventional textbooks, and the study questions are fewer and less thoughtful--an expected and acceptable trade-off given that this book has the potential to save students hundreds of dollars.
