This text avoids the use of ethnocentric names and concepts as far as I can see. The text does not dive into the controversy, merely puts forward the biological information as it should. a. how selective forces change the allele frequencies in a population over time This is well done and contributes to student learning as concepts will build upon one another as higher levels of organization are discussed. glycogen. Please check your connection and try again. Additionally, there is a lack of images of people in the text, so I supplement the information presented with "scientist spotlights" to highlight diverse scientists in the wide range of careers available with a Biology degree. 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). Students can download this text for free, view it on their devices and print it out. For example, figures 7.6-7.8 all label the steps of the reactions taking place, which I found useful. This makes it easy to expand on particular topics, replace a section with other reading, and tailor the text to the objectives of a course. The second-weakest section for my course is on developmental biology, and there are some other texts that offer more (e.g., on polarity genes, segmentation genes, and hox genes). Topic completely missing from the book or coverage is so poor it is unusable, in my analysis were: However, as with any subject, certain topics in generally biology (e.g. I could find only a few minor grammatical issues. The text has some good features. The illustrations were also very helpful and I can see them providing a lot of help to those visual learners. However, the likelihood of an instructor assigning those subsections at random is very low, so I don't think it would be a problem. Furthermore, some of the links that take readers to additional multimedia features do not work. On page 313, the explanation of The Red Queen Hypothesis in the Evolution Connection is very weak and unclear. Fungal and protistan cells also have cell walls. No, not all protists have cell walls. Some terms were utilized in strange ways, and I felt some of the definitions could be altered a little to be more precise. Also, the glossary has terms that are not fully defined. I supplement many Hawaiian examples throughout because our flora and fauna are unique, so students don't always understand references to mainland species. On page 486, this sentence is incomplete: Define species and describe how species are identified as different. The critical thinking questions are generally pretty good. This is not correct in the formal sense of classification. I felt like there was too much detail on some processes, and too little detail on other topics. Some chapters contain references to "recent work" that will not be recent in a few years, although the text also does not give specific years the work was published. They are very basic and do little to help students visualize biological concepts and structures. I did not notice any inconsistencies in this set-up or within terms. A suggested and testable explanation for an event is called a ________. For instance, in Figure 40.15/Page 1178, the branch after the Thoracic aorta is named the Abdominal aorta; its branches include the Celiac trunk, Superior Mesenteric artery (mistakenly labeled as Gastric artery), and it becomes the Common Iliac artery (mistakenly labeled as Iliac artery) . I would also recommend reminding readers where the answers to the comprehension questions can be found (i.e. The topics that travel into an introductory biology text are topics that are rarely controversial or inadequately supported by scientific vetting. In the online version, each term is hyperlinked to the appropriate section, whereas in the pdf index, the link goes to the key term list at the end of the chapter. I loved the Link to Learning, I have used a number of the linked sites in my courses however it did open up a world of other valuable sites. The language skills needed are consistent throughout the text and the organization of the material is consistent. The short video is correctly labeled as dispersion in Wikipedia rather than as diffusion. Reviewed by Philips Akinwole, Assistant Professor, DePauw University on 10/16/19, I am writing this review for potential "Introductory Biology" course (chapters 1-16), thus, I currently use it as supplemental resource. No insensitive or offensive language. Looks like what you have put together is going to pretty much fit the bill! 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. read more. In terms of writing and clarity, some chapters are great, others are mediocre. Few chapter, though, like Gene expression might need more detail/clarity. For example, the large aquatic reptiles of the Mesozoic Era were not in fact dinosaurs; they were just contemporaries of dinosaurs. The text is easy to read and flows nicely. These details will inevitably be explored more deeply as students progress through their program of study. anabolic (also anabolism) pathways that require an energy input to synthesize complex molecules from simpler ones. Occasionally figures also look grainy / blurry or as if they are low-resolution images (ex. 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. The type of logical thinking that uses related observations to arrive at a general conclusion is called ________. 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. However, I have found some points of disagreement that are perhaps matters of emphasis, philosophy or omission. 1443, after the 2nd word of the last paragraph. For instance, in the cell reproduction chapter, the metaphase, anaphase, and telophase sections are each described using just 3 sentences. I havent gotten that far ahead, though Ill probably be skipping that one for now since I dont plan to cover it until next semester. This is a very comprehensive textbook that provides an appropriate balance between the different fields of biology. read more. I also found the instructor resources to be consistent. Weballosteric inhibition. Most chapters lack the highly detailed summary images that most will be familiar with from commercial texts--for example, a summary image of cellular respiration or cladograms for major phylogenies. Its a shame because it would have been relatively easy to bring in a great deal more diversity in portrayals of human scientists. Because this content is designed for an introductory Biology majors course, there is quite a bit of jargon and technical terminology. The chapters are clear and concise. Pinacocytes are epithelial-like cells, form the outermost layer of sponges, and enclose a jelly-like substance called mesohyl. Compared to conventional textbooks, it is typically accurate and perhaps a little above average in freshness. GitHub openstax / cnx-recipes Public Notifications Fork 14 Star 5 Code Issues 81 Pull requests Actions Projects Security Insights New issue I greatly appreciated the underlying theme of evolution and careers in biology. For each section there are 2-4 objectives for the students to focus on. Thats because, we at the Vending Service are there to extend a hand of help. It was initially well-written, and has benefitted from additional suggestions and corrections by users. I have found a few broken links throughout the text. I like how vocabulary words are in bold as this makes it easy for students to make flash cards. I absolutely intend to use it to replace expensive textbooks. I have found the content for this purpose mostly comprehensive, with some need to supplement. The index and glossary are fine. On page 96, the text states, The structural difference between a normal hemoglobin molecule and a sickle cell moleculewhich dramatically decreases life expectancyis a single amino acid of the 600. No, the sickle cell hemoglobin only decreases life expectancy in homozygous individuals. As a result, for this level,I am pleased with the level of accuracy. Since this is an introductory biology textbook, the topics are rather standardized across textbooks in this market. Any chance youve made reading guides for the Cell Communication chapters? There is consistency with the presentation in each of the chapters with the art inserts and the glossary and test questions. We have a two part biology series for majors and pre-nursing students that should have a good grounding in biology. The coloration of these figures should also be improved for contrast. Terminology and organization is consistent. The modularity of this textbook is excellent. The video links I checked were generally good, although a few include misconceptions. Something especially unique about this book is the Career connections Section within every chapter. In contrast to some introductory biology textbooks that focus almost exclusively on humans, this text consistently includes examples from all three domains of life, making the content more applicable to students with interests in different areas of biology. Good to have a glossary at the end of each chapter but the definitions could have more depth and research. Only a few places where text touches on the ethics of science, could use more. This text, while far from being obsolete, probably needs an update as it was finished in 2018. I noticed no problems. It appears the text has been crafted to meet the needs of a general/non-major biology course that might be more human-biology based as well as a more typical (in my experience) two semester foundational course for biology majors. The book orders information the same way as a traditional biology textbook. The order of presentation is basically the same as any other textbook. I noticed one broken video link, but that's the nature of this kind of resource. Very evident in Cellular respiration chapter This textbook is mostly suitable for 100 level introductory biology for non-majors. read more. Include blood in pH figure 2.19. No grammatical errors were noted. Additional colors in the background and/or headings would help break up the material. the study of living organisms and their interactions with one another and their environments. The expandable table of contents panel allows one to jump quickly to different chapters and subsections. In general, I did not locate any grammatical errors. Topics are well covered and relevant, mostly. All of these interfaces are image heavy. On page 54, this sentence requires a fuller explanation: Cells can only survive freezing if the water in them is temporarily replaced by another liquid like glycerol. Consistent and flowing from one logical chapter to the next. I must admit that at first glance this book looked to me to be much less glitzy than traditionally published books, without all the bells and whistles, the fancy graphics and human interest stories. This is consistent across the textbook, with the chapters following what I would consider to be a logical flow. The organization is so similar, in fact, that I have to believe it was intentionally pattered, sometimes chapter-by-chapter, after offerings from major commercial publishers. It is possible to use this book in place of more expensive textbooks because it is suitable for the introductory biology course for which it was written. However, I wonder if there might be a better way to organize some material. The content of the text is generally accurate but not uniformly. and Biology by Russell et al which are all well suited for a two-semester general biology sequence such as is typically taken by biology and science majors. Few minor errors are present in some materials. The basic content doesn't seem to be at any more risk of becoming dated that a traditional text. My suggestion would be not to completely overhaul the text exactly but maybe update the ancillary materials in a way that teachers and students are introduced to new discoveries and new techniques on regular basis. Either way, the machines that we have rented are not going to fail you. The rest of the content is current and relevant. I greatly appreciated how the text explained scientific concepts in ways that students would be able to understand. Definitely share, Im in that group. Terrestrial vertebrates differ in the source of body heat and in the variation in temperature they experience and can tolerate, not in the temperature of their blood. Generally, graphics are of lower quality and some study questions are less thoughtful but links to animations and talks are a great perk! Consistency is good but not great. Additionally, I like the summary tables at the end of many sections and/or chapters (particularly cells and membranes). On the other hand if the authors wanted to dwell on minutia they could say that catabolic reactions also require input of energy to overcome the energy of activation. This will confuse students, many of whom have trouble grasping induced fit, which is introduced on the next page. The links to learning videos are often from utube with no evidence that they come from scientific peer reviewed sources. Please check your connection and try again. I found few errors. What I found particularly refreshing was the inclusion of a biotechnology and genomics chapter later on in the book. Overall I feel this textbook is easy to use and easy to read. 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. The book is reasonably current, as much as the most recent editions of mainstream print biology texts. anabolic (also anabolism) pathways that require an energy input to synthesize complex molecules from simpler ones. There is adequate coverage of evolutionary processes and mechanisms of speciation in later chapters. The PDF of the text is over 1500 pages in length, making it very long (by print standards). read more.

Each chapter has a number of useful key terms and definitions, a chapter summary, as well as review questions for the students. One critique is that the learning outcomes at the beginning of the chapter and the visual connection and review questions at the end of the chapter are mostly lower order cognitive skill questions (i.e. For any of the following that can exist as isomers, state the type of isomerism and draw the structures: are not subject to the Creative Commons license and may not be reproduced without the prior and express written When more depth is required, other web sites and tutorials can be added to the students' reading materials. read more. Furthermore, there are a great many photos in which the hand of a human being is shown as holding a sample, such as holding a test tube or holding an animal studied in the field. One of the most attractive features of an open source text is that it can be more readily revised that hard copy since it is a web-based text. Reviewed by Paul Heideman, Professor, College of William and Mary on 6/20/17, 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. Or take this example, If the solute levels increase beyond a certain range, a hormone releases that slows water loss. It seems that what the authors intended to convey is that a hormone is released that slows water loss, and this may be perfectly obvious to a well-informed reader. The website lets you easily navigate directly to specific sections. In addition, it streamlines many of the chapters to cover just the essentials, so it is half the length of a publisher textbook. Each carbon atom can bond with as many as________ other atom(s) or molecule(s). The textbook is aimed to provide fundamental knowledge at a general reading level. The sentence conveys an implicit idea that ALL variation in a species is attributable to genes. One very serious weakness of this text is the art: the figures, the animations, and the Art Connection features. 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. %PDF-1.3 Aside from the figures, other aspects of the interface function well. Still, if you prefer to create your own lectures, this text is without a doubt a top choice. 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."). Links. On page 54: Unites States Independent Assortment is discussed in 12.3 along with Linkage, but Linkage section did not provide any information about determining the distance between and order of genes on chromosomes. 9. There is a second, random "s" after the word success. I felt the order in which the authors approached topics was intuitive to how a student might learn the topic. Im sure labeling will get fixed in the next revision that will be available soon. read more. I thought many images had a random quality. I think it would be difficult to teach the first three units out of order or to select only a few chapters/sections to include in a course, but this has much more to do with the interrelated nature of the material itself, rather than the design of the text. This review was collaboratively written by Dr. Heidi Sleister and Dr. Debora Christensen. WebCh. Students who did these problems would gain in understanding, but I think the questions are not especially strong with respect to developing new skills at applying the concepts, doing broader analysis, or synthesizing ideas. I found nothing in this chapter which could be construed as offensive or insensitive. Perspiration is the body's mechanism for eliminating this heat. In this reviewer's opinion the modularity followed in this text is very helpful for the intented target student audience students who are freshman non-majors. Overall the topics are presented logically and students can follow. I primarily used PDF copies, but did spend one day using the online version without issues. I found only one photograph of a named female scientist, Elizabeth Blackburn, in Figure 14.16. For example, redox reactions are briefly described, but their value in removing free energy from glucose molecules is given short shrift. On page 1360, the explanation of keystone species is very weak and insufficient to answer the critical thinking question at the end of the chapter. For example, at the time of this review in December 2016, statistics and citations in the book date primarily to 2012 and earlier, and some recently hot topics like CRISPR are not yet covered. The content, as least in the chapters I cover, is extremely similar to my current The first forms of life on Earth were ________. The genetics section of this book appears to be consistent. I found that the level of detail is appropriate for a lower level undergraduate biology course. It has a good online index that is searchable. Scientists are not ones to dress up language, aiming instead to say things as precisely as possible. Also newer information is missing in some of the chapters. I think the modularity of this book helps with the flow. There is no discussion of the temperate forests on the west coast. As noted above, in some cases the art is not consistent across ideas and within and between chapters, and this could be confusing for a student.
