But this is not necessarily a bad thing, as it should make it easy for all instructors (regardless of their teaching style) to make the change and substitute this book for an equivalent print text. This would be what good instructors always do, but new instructors often have to take more of their clues from the text. The depth at which material is covered seems appropriate for a first year majors biology course. Students will be confused and uncertain how the two strands are represented. Unfortunately, for many of the students at my college, the reading level of this text is difficult. It was easy to download and view. The table of contents is not available on each page, so navigation other than directly forward or backward is difficult. I believe this will allow for easy alignment into any new or existing Biology course. 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. However, there is not enough explanation or detail provided for most students to make any sort of meaningful connection. Some of the figures in the PDF have very small components that cant be magnified (they just become pixelated if one tries). Each chapter begins with a list of learning objectives. The website lets you easily navigate directly to specific sections. Reviewed by Emma Murray, Instructor (Biology for majors), Aims Community College on 7/23/19, 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. Overall, this is a well assembled textbook that would be highly appropriate for an introductory biology course for majors. read more. In doing so, however, care should be taken to not divide the topics where some continuity could be lost. Overall the writing is clear. I found the online interface difficult to use, because the pages load slowly and only one section of a chapter was visible on the page at a time. Easier import power into different LMS platforms. Given that many students struggle with thoroughly understanding evolutionary processes and have misconceptions regarding evolution, this does seem to be an oversight. The figures have a hyperlink in the text that the student can click on. 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. I think all these factors can enhance the learning experience and increase students' subject-matter comprehension. The text is written in a clear and easy to comprehend manner. The chapter appears confused about how time is represented in phylogenetic trees, saying both that trees do and do not have a time axis. Chapter and section content is consistent throughout. If xenon has an atomic number of 54 and a mass number of 108, how many neutrons does it have? 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. It is possible to see the resolution of every correction suggested over the entire history of the book when it was initially published in 2012 at: https://www.openstaxcollege.org/textbooks/biology/errata. I haven't had issues using the interface. Since the text is foundational, many of the subjects aren't changing rapidly. 19. Topics presented are organized in a logical manner with topics building on previous sections. I focused in on Chapter 15: Genes and Proteins. The terminology and framework are consistent throughout the whole text. Each carbon atom can bond with as many as________ other atom(s) or molecule(s). It is a complete package! In truth, both fields are equally rigorous and important, they just study different parts of our world. The comprehensiveness varies but is overall mostly appropriate. The text integrates in-depth concepts over a broad range of topics. All texts tend to emphasize some areas over others, and this is no exception. The set up of the text book is easy to navigate and the framework is consistent. I intentionally stepped into chapters out of order and found them to be appropriately modular. Images are detailed and appealing to the reader. Thanks so much Im using the AP Edition of OpenStax and am modifying these to fit that text I know how much effort and work go into the creation and thank you for even sharing what you have! The content of the text does have some inaccurate sections. Generally, this text meets the level of accuracy I find in other texts. For my purposes, the weakest section is on phylogenetics, but I always need to supplement that section of any text. While the content is there, they are not as elegant as one would find from a mainstream publisher (for example, the illustrations of the cell are 2-dimensional). While the authors/publisher did not create the video, they are responsible for it being embedded in the textbook. 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. read more. Not sure this is a major hang up, just something I noticed. 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. Overall the content accuracy was on par with an introductory course. read more. I believe this is where the instructor comes in to highlight other scientists and contributors to the field. The first forms of life on Earth were ________. 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. Biologists refer to this fit as adaptation, and it is a consequence of evolution by Justify your answer. I noticed one broken video link, but that's the nature of this kind of resource. However, they are inconsistent in the quality of the website links. Each section is relatively short and self-contained. The sections (chapters) are quite small, which helps the compartmentalization of the material but at times feels a bit choppy. 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. Two, some chapters simplify explanations. The text is very consistent in terms of terminology and framework. In some places, information is repeated within a paragraph. Content is consistent with any basic entrance level Biology course. This review will focuses specifically on a representative chapterin this case, Chapter 7: Cellular Respiration. The Career Connections sections are a nice addition that students will be able to explore when considering career possibilities in science. On page 30, the text says, Many organisms belonging to the Archaea domain live under extreme conditions and are called extremophiles. This would be fine if the text then went on to explain that we now realize that Archaea are far more widespread than previously thought, but the discussion ends there. As stated above, for those areas in biology where there have been significant advances over the past decade or so (e.g. See Vogel (1994) Dealing honestly with diffusion. The significance of these comparisons is not explained. Reviewed by Mark Wagner, Instructor/Life Sciences, Portland Community College on 6/14/21, I found the book to cover the topics in good depth, definitely a lower division, major-level text Which of the following statements is not true? Content is presented in a logical fashion, building upon one another as the book progresses. Unless I missed it, the R in Figure 2.27 is undefined. Figures were also accurate and current. 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. The book is comprehensive and suitable for use in a 2-semester (year long) college-level biology/science majors general biology sequence. The approach of including Hardy Weingberg under population evolution and drift, flow, mutations, and natural selection under population genetics is different from what Ive seen in other books. read more. 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. The index at the start of the text is very useful for navigation. The writing style is easy to read and is well written for the freshman/sophomore level. I did not examine all of the review questions in the 26 chapters I engaged, but I came across one that to my mind rises to the level of error (Section 19.1 Population Evolution. Over the first 16 chapters, the text is consistent in its framework, as well as in its design. I didn't see anything that made this book more or less culturally relevant than other texts. This is a science textbook, so there are very few places to talk about other cultures and ethnicities. This textbook was comprehensively organized and populated with topics. The abstracts are a good concise summary of what the chapter intends. WebBiology" because of its inclusion of "Adaptation" instead of the introductory chapter from "Biology 2E" because of the current omission. As I would expect, this chapter is organized in a logical, straightforward manner. They create unnecessary clutter on the page / in the figure caption. Links to Animations Concepts The text book uses accessible prose while at the same time expecting the student to remain current with the material learned in previous chapters. Graphics However, there are several mistakes that do need to be corrected. But, in the case of mitosis, the lack of a good figure of the mitotic spindle is notable. Gene flow, the movement of alleles across the range of the species, is relatively free because individuals can move and then mate with individuals in their new location. What I found particularly refreshing was the inclusion of a biotechnology and genomics chapter later on in the book.

In the survey of the major groups of organisms (Protists, Fungi, etc.) This book will work taken as a whole, or taken in parts. The organization makes sense and flows well. Otherwise I had no interface issues. The text is comprehensive in its coverage of the typical materials for a non-majors introductory biology course at the 100 level. It may be more suitable for Canadian students if there were more images from Canada-based resources. I appreciated the additional learning links included within the chapter, particularly the one detailing transcription and translation, allowing students to practice this concept in a manner likely to be encountered on an in-class evaluation or in other evaluations the student may encounter later in their career. Generally, graphics are of lower quality and some study questions are less thoughtful but links to animations and talks are a great perk! One inconsistency of note is the use, or lack of use, of graphical phylogenetic hypotheses. Putting these pieces together would help students gain a more unified understanding of cellular respiration as one component of larger biological processes. 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. On pg. I taught an earth science class last year for the first time and was thinking about compiling those resources. and Biology by Russell et al. However, it still seems slightly dated even with this consideration. ISBN. Clear subtitles and logically arranged chapters. I did not notice grammatical errors, although there are occasional typos. Which of the following sciences is not considered a natural science? The answer is that they cannot do it and are constantly dying. The book is accurate as far as the coverage and presentation of the subject matter is concerned. In figure 7.9 (Citric Acid Cycle), this convention is jettisoned. The section dedicated to gene therapy is very short and there's no specific mention to CRISPR. In general, it hits right at the level its aimed at. I have found the content for this purpose mostly comprehensive, with some need to supplement. The sections, though integrated, can, in many cases stand alone as an introduction to the topics. The lengths of the paragraphs are rightly tailored for mobile devices such that continued reading interest is sustained. They should be discussed along with cytokines. inhibition by a binding event at a site different from the active site, which induces a conformational change and reduces the enzyme's affinity for its substrate. Unit 7, Chapters 33 41, covers the major systems of animals, including digestive, nervous, sensory, endocrine, musculoskeletal, respiratory, circulatory, excretory, immune, and reproductive systems. Figures and images are places between paragraphs. Especially in the first image for the chapter. An instructor who was teaching with this book would have to be able to create/provide this kind of summary for students on their own or from another source. 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. 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. This text easily lends itself to be parceled into units/modules, such as between two semesters. In Chapter 18, the text only includes the biological species concept, with no discussion of its weaknesses or limitations. 11. It would be easy for the instructor to build off the foundation that was laid out in the text. I have smaller, one week chunks and this book will still allow for that approach, using chapters or parts of chapters each week, as well as taking parts of chapters in isolation, or in conjunction with other chapter parts. There are no cultural insensitivities or biases in the text. The links to learning videos are often from utube with no evidence that they come from scientific peer reviewed sources. On page 496, the explanation of punctuated equilibrium is very weak. The book followed a typical format of introducing biological concepts starting with cell and ending with community biology. All areas of introductory biology were covered. These images are similar or complimentary to others displayed in the main text, and labeling them as Art seems strange. 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. While the authors are currently relevant and up to date. 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. Both online and .pdf versions have links embedded in the Table of Contents, making it easy to skip around through the book as needed. Why are two base pairs (T-A and incorrectly labeled C-G) shown? Comprehensiveness in an introductory biology textbook is a daunting issue: A text needs to be sufficiently comprehensive to meet the needs of adopters in courses of widely varying organization and focus, without at the same time becoming so massive as to be unwieldy.
