You have been redirected to the 4th edition of Cell and Molecular Biology 4e: What We Know & How We Found Out (CMB4e). CMB4e is updated (as of 2020) and enhanced from previous editions, with new content and no loss of original content. All of the earlier editions and versions of CMB will still be available, if necessary by request directly from the author (firstname.lastname@example.org ). However, we hope that you will like the improvements and that you will find CMB4e a useful upgrade and update. Of course, any and all comments that will help to improve the book for the next release are welcome.
CMB4e is the latest edition of an interactive Open Educational Resource (OER) electronic textbook (iText), available under a Creative Commons CC-BY license. Like earlier editions, CMB4e opens with a short history of the discipline and a discussion of scientific method. The book remains focused on the understanding of evolution that informs all of the life sciences and continues to provide experimental support for what we know about cell and molecular biology. Having a sense of how science is practiced and how investigators think about experimental results is essential to understanding the relationship of cell structure and function, not to mention the natural world around us. CMB4e is available in three versions (plus a sample chapter):
- In the Basic CMB4e iText, each chapter introduction includes learning objectives and context-embedded links to short explanatory voice-over PowerPoint recordings (VOPs) and other web-links of interest. QR codes allow the reader just-in-time access to the VOPs on smart phones or any camera-enabled portable device.
- The Annotated CMB4e adds pre-written, interactive context-embedded Challenge boxes to the Basic version of the book. These contain open-ended questions that expand on text readings. Any or all of them can be the basis of informal class and online discussion or as graded assignments.
- The Instructors CMB4e iText adds a series of 25 Words or Less essay questions that the author used as short (i.e., easy to grade!) writing assignments to strengthen student’s critical thinking and writing skills.
- A CMB4e Sample Chapter includes examples of instructor’s resources
Freely download the sample chapter by clicking the CMB4e Sample Chapter link below. To download the Basic, Annotated or Instructors CMB4e iText, choose and click the desired link below. A short form will appear. Please provide a bit of (anonymous) information, submit the form, and then download your iText. All iText users can enter their own digital annotations or print the text and write in the margins the old-fashioned way!
If you are an instructor, click the Instructors CMB4e iText link below to fill out and submit the short form that appears. Instructors will receive both PDF and MS-Word files of all versions the iText to use ‘as is’ or as the starting point to build their own custom iText. After adding or deleting content, annotations, assignments, etc., the customized iText can then be the required (or recommended) course content, to be distributed to students under the guidelines of the Creative Commons CCBY license. I encourage instructors with an interest in interactive learning and who are concerned about the high cost of textbooks to customize one of the CMB4e versions to engage their own students in thinking about science. You can even ask students to try their hand at writing their own Challenge Box or essay questions, perhaps reflecting what they are wondering about!
If you are a student, check out the links in whichever version you are reading and to think about how good experiments were designed, how data was interpreted, and what questions the investigators (and we!) might want to ask next. If you are using the Annotated or Instructors CMB4e, I encourage you to accept the challenges in some of the Challenge boxes (even if they are not assigned by your instructor)…, and to wonder about cell and molecular biology and how it all works!
