Instructors frequently choose to omit one or more early chapters for the sake of time and because there may be an assumption that students are already familiar with those concepts. This is often a matter of opinion across Biology professors, so that is not surprising. GitHub openstax / cnx-recipes Public Notifications Fork 14 Star 5 Code Issues 81 Pull requests Actions Projects Security Insights New issue I do wish there was more content on plant biology. While there are probably a few more grammatical errors than would be typical for a traditional textbook, I have no problems with the grammar of the text. Clear and defined, but definitions can be overly complex depending on the rigor of the class it is used in. One way that heat is transferred from place to place inside the human body is by the flow of blood. WebTotal Pages Answer Key N/A. Most of the material taught in introductory biology courses has not changed in the last 15-20 years and this book is certainly up to date. Here are some examples: Before I adopt this text, I would really like to see the quality of these resources. However, unlike most textbooks, it is simple for anyone to submit a correction, so these errors are corrected more efficiently than can be done for most textbooks. Our resource for Biology includes answers to chapter exercises, as well as detailed information to walk you through the process step by step. There is coverage of all levels of organization and no bias is evident in coverage of molecular versus ecological topics. R0Et|K1gk(XEM%vxy8M17. The online version has features to search, highlight (with five color options), and add notes. Topics presented are organized in a logical manner with topics building on previous sections. The text does a great job of discussing important terms in sufficient detail and avoids extensive jargon. New stomach cells are constantly produced to replace dead ones, which are digested by the stomach acids. Much of the genetics content that I would use from this book is sort of timeless in that it hasnt changed in many years and is unlikely to change in the near future (meiosis, mitosis, mendelian genetics). The section on temperate forests is actually inaccurate in spots, stating that deciduous trees are dominant in this biome, and omitting the fact that coniferous forest are also dominant in these forests. I compare the chapter from Biology 2e to both the first edition Openstax Biology and a traditional introductory text from a major publisher. There is no open source zoology textbook available, and in any case, the published texts tend to be too heavy on facts and too weak on what I present as the logic of zoology the evolutionary reasons or biochemical constraints that are common drivers of the structure and function of animals. The text is written in an understandable, clear manner, and all major terms are bolded and referenced in the end-of-chapter glossary. Diversity of life and physiology get a lot of attention and surprising detail for an introductory textbook. The book is divided into subsections, each of which contain several chapters relevant to that topic, and chapters are further broken down into subunits. The authors did well in presenting multiple controversial topics within numerous sections throughout the book. If so, how? The genetics section in particular seems to be modular. There is really no other way to deal with this material. The structure of the text is similar to most text books for this level of biology and the units are divided appropriately. Since the review prompt asked for me to consider inclusion specifically, I made a point to page through the book, one page at a time, specifically looking for portrayals of human diversity and humans working as biologists/scientists. Journalism, Media Studies & Communications. The modularity of this textbook is excellent. But this is no different than reading a popular magazine that has different articles authored by various writers. As I would expect, this chapter is organized in a logical, straightforward manner. The chapters are divided into topical sections, making it easy to assign or not assign specific topics. However, it still seems slightly dated even with this consideration.

The ammonia vapor will diffuse, or spread away, from the bottle, and gradually, more and more people will smell the ammonia as it spreads. No! That might be true in a sense, but relative to next generation, high throughput techniques, it is a very small portion of the sequencing actually happening in this day and age. Sometimes a bit on the technical side, but the publisher book had the same issue. The subsections are natural and permit the instructor to easily select the specific topics they wish to cover or not. For these reasons, I think this would be a very difficult text for a new instructor to teach from. For example, in 4.1 Studying Cells, one learning outcome is "Describe the role of cells in organisms.". The addition of key terms at the end of the chapters also adds a bonus summary for students to use as a resource to gauge their understanding of course concepts. "Connection" sections (except for "Art") were for the most part excellent and bridged concepts with real-world issues. read more.

It includes video embedded that will be updated as needed. The capacity to have external links embedded within a digital textbook can be a real strength for reinforcing content. The content, as least in the chapters I cover, is extremely similar to my current This is false, of course. Examples used earlier in a given chapter may be revisited later in that same chapter or unit, facilitating continuity and flow. The book is nicely comprehensive in its overall selection of units and chaptersall the basic components of any standard semester-long or year-long general biology course for majors or a mixed nonmajors/majors audience. While it puts major discoveries into some historical context (Mendel is discussed at length) it forgoes that context in more recent discoveries (epigenetic and its historical context). I still would not recommend my students this current version as it may not be easy to follow and is at times confusing. The text is organized in a clear and easy to follow manner and provides formative assessments throughout so that students may gauge their learning. I thought that the authors did a great job of providing unbiased scientifically based information in this textbook. Again, the instructor can supplement. I thought the explanations were very specific and well versed. In general, the terminology and nomenclature is consistent throughout the book. Paternal leakage means that not every mitochondrial DNA is from the female. There are no issues with the download at any time and website does reminder the reader to use the chrome or any other web browser than IE.

CRISPR-CAS technology is sufficiently explained for an understanding of the concept without going into too much detail. Many figures are not readable until viewing at 200% or even 300%. plants microorganisms birds dinosaurs 5. I believe this is where the instructor comes in to highlight other scientists and contributors to the field. As such the text was lacking in examples and depicting a diverse cultural tone and images when possible. Most of the "skin tones" colorized in these diagrams where light beige to pinkish tan, but it would be easy to resort to a pale olive tone or even a neutral light grey if a darker brown tone would make it difficult to visualize the line drawing of the system portrayed in the image. I saw very few references to race/ethnicity in the text, Reviewed by Thomas Giardina, Assistant Professor, University of Delaware on 5/21/18, This review will focuses specifically on a representative chapterin this case, Chapter 7: Cellular Respiration. Nothing caught my attention regarding Canadian content. 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. This is a very nice textbook. On p. 125 the authors write: "The X chromosome is one of the two human sex chromosomes, as these chromosomes determine a person's sex. There is a bit of redundancy when talking about amino acid structure, as every time amino acids are mentioned, there is also the mention of the amino group and carboxyl group. There is little consistency in the images- some ar every nicely edited and some are difficult to see. I was wondering if you have Chapter 12 (Genetics)? On page 24, the term germline cells is used but is not clearly defined. In many cases, the book is written in very simplistic terms, which is likely designed to hold the readers interest. There is consistency with the presentation in each of the chapters with the art inserts and the glossary and test questions. Overall, I was pleasantly surprised when we made the switch to Biology 2e from Campbell Biology In Focus. I may discover more inconsistency when I am using it with my students. Getting students to read textbooks is always a struggle and so I do think that making the layout appear less daunting would be an improvement. More vocabulary is presented which is a good thing to expose the students to. Terms and concepts are very well explained and significance is emphasized. They followed the format of most other textbooks making a transition to OpenStax from Cambell or Biology in Focus simple. I found the text to be highly modular. I think that in an introductory course, it is more important to convey the more general, big picture of concepts without adding confusion with over-exertion of details. Some of the links on the textbook take you to trusted sources such as Khan Academy and TED talks, but others dont look very reliable to me. The grammar in this text is excellent. I would like to see greater use made of graphical phylogenetic hypotheses ("phylogenetic trees") in the diversity overview sections, and in other areas where the evolution of key characteristics is discussed. This structure is also attractive to instructors as it allows us the freedom to pick and choose textbook content to assign. Chapters can be easily integrated into a learning platform to facilitate weekly reading assignments. Much of the time, the text took on a more conversational tone than I was expecting, which I feel will appeal to readers. I did not notice anything glaringly outdated, but given the speed of new research, it is likely that regular updates will be needed to keep the book current. There are very few grammatical or typographical errors, and these can easily be fixed in subsequent versions. For example, there is a box in the plant section discussing whether green algae are considered as plants. Many terms are used before they are defined. Core concepts for introductory level college course are addressed in sufficient detail, without overly complicating the material for this audience. As with other textbooks I have used in the past, students do not read chapters unless you give them some kind of assignment that goes with it. While the authors have consistently kept descriptions to the minimum, it would be unfair to expect great explanations for the various topics in biology some of which we have entire courses designed for them. There are some areas of the book that would benefit from additional copy editing. I did not find anything culturally insensitive. Support resources at the end of the text are thorough and well organized. Yes it is but a lack of internal referencing is evident. I believe that more modern books will more thoroughly discuss the human element to conservation and management. Sections can be used individually.

This is a great chance to show the accomplishments of a brilliant woman. This text covers all subject matter used in a one semester introductory biology course. Overall this text covers each topic in adequate detail and provides enough detail and content for a two semester coverage of biology for majors, especially if this text is used alongside additional instructor input and labs. In many cases, we found this necessitated rereading and trying to interpret meaning from sentence context. Within chapters some of the graphics are labeled art connection, evolution connection, etc. Content viewed appears to be accurate and unbiased. These were accessible with a QR reader for the offline versions. stream I am reviewing this textbook not for a first year course in introductory biology, but for a second-year one-semester course on the integrative biology of animals. I felt like there was too much detail on some processes, and too little detail on other topics. The chapter appears confused about how time is represented in phylogenetic trees, saying both that trees do and do not have a time axis. This book has a degree of modularity that should readily accommodate a variety of approaches for covering its topics. If xenon has an atomic number of 54 and a mass number of 108, how many neutrons does it have? The core concepts of biology can be taught in many different orders and there is not one best linear path through the material. The links to learning videos are often from utube with no evidence that they come from scientific peer reviewed sources. ions neutrons neutral atoms isotopes 6. and Biology by Russell et al. Overall, this book provides a mostly adequate resource for teachers who are trying to save on textbook costs. I focused in on Chapter 15: Genes and Proteins. As stated above, for those areas in biology where there have been significant advances over the past decade or so (e.g. I put them up as I go, but remote teaching this year has really shifted my focus. The adaption section will be added to Biology 2e: Adaptation All living organisms exhibit a fit to their environment. Finally, we biologists also know that there are many humans born intersex, and their existence is completely ignored by the statements made by the authors. No culturally insensitive or offensive material was encountered. The book would benefit from greater use of diagrams, charts, and images (and even lists and bullet points) to cater to visual learners. Images and figures need revision as many are displaying with poor resolution in the pdf version. It is easily adapted, and accessible on multiple devices. The reviewers did not notice any bias in the text. The website was easy to use and search. This is not an enlightened book, but I have not found it to lack images and examples from across the spectrum of humanity. Images in the text included a variety of people from different races and backgrounds. Granted that the texbook is "inaccurate" with respect to T cell subpopulations (at this detail level), but if one wants to know more about T-cells, then perhaps an Immunology textbook would be more appropriate! Colored images work better for the students since I emphasize that is publisher is paying more for the color it must be important. The basics / foundations were covered in an appropriate manner so that the text will not become out of date very quickly. Nitrogen fixation and plant defenses are not well explained, and deamination and cation exchange dont come up in a search. After one semester of using Openstax, I have received positive feedback from students. I noticed no problems. cellular respiration or molecular genetics) will rely on knowledge gained from the chemistry and cell focused parts, so naturally in distributing the subject matter among several courses proper sequencing of those courses in the curriculum is desirable. I selected Cellular Respiration because this is a complex, multi-step concept which is challenging for many students. read more. There are typographical errors that can be easily corrected during a revision. Some terms were utilized in strange ways, and I felt some of the definitions could be altered a little to be more precise. Im sure there were many others. The prose is consistent and accessible to students. The art is well done and has clear images that are well labeled. Section headings and learning objectives are useful in breaking up the material into smaller, more digestible components. This example most closely resembles which type of reasoning? Each chapter is broken up into sections, generally between three to five sections per chapter (but ranging from two to seven). Content did not seem culturally insensitive or offensive. The book covers everything a traditional introductory biology major textbook covers at an average level of detail, organized in the usual hierarchy from atoms to ecosystems. 54L,x

It covers all of the same topics as books sold by the major publishing companies, but it's free to the students! Support resources at the end of Students will be confused and uncertain how the two strands are represented. The biologically accurate terms are ectothermic and endothermic. This might be particularly true in some of the biochemical terms and pathways presented. However, I actually find this quite refreshing, in that there is more of an emphasis on essential information. Non-major students who dislike biology because of the very intricate details of glycolysis or the steps in DNA replication would be the best sort of market this book could reach. However, while more topics are covered in the Biology textbook, the amount of comprehensiveness for each Chapter is only minimally expanded from the Concepts of Biology textbook. Reviewed by Conner Sandefur, Assistant Professor, University of North Carolina Pembroke on 6/19/18, This text covers all subject matter used in a one semester introductory biology course.
