The 3rd edition of Cell and Molecular Biology 3e: What We Know & How We Found Out (CMB3e) is the latest edition of an interactive Open Educational Resource (OER) electronic textbook, available under a Creative Commons CC-BY license. Like earlier editions (and like most introductory science textbooks), the third edition of the CMB3e iText opens with a discussion of scientific method. CMB3e retains its focus on 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.
The CMB3e iText is available in three full versions: Basic CMB3e, Annotated CMB3e and an Instructor’s CMB3e. In the Basic CMB3e 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 enable just-in-time access to VOP links on smart phones, tablets and even hard copies of the iText. In the Annotated CMB3e, Interactivity is further supported by context-embedded Challenge boxes. These typically contain open-ended questions that expand on text readings, and that can be the basis of discussion or assessed assignments. The Instructors CMB3e iText adds a series of 25 Words or Less short writing assignments, intended to be assessed and that should strengthen critical thinking and writing skills. Examples of instructor’s resources are included in a CMB3e Sample Chapter.
Instructors and students can freely download the CMB3e Sample Chapter, Basic CMB3e and Annotated CMB3e iText. Instructors can request the Instructors CMB3e iText. All iText users can create their own digital annotations or download and print the text and write in the margins the old-fashioned way!
Instructors can use any version ‘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 CMB3e versions to engage their own students in thinking about science. I encourage students to interact with the iText and 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 select one of the full versions (not the sample chapter), you may be taken to a usage survey. I ask that you complete the form so I can better understand how you might use the iText.

The Basic, Annotated and Instructors’ versions of CMB3e were published in the fall of 2018. CMB3e is updated and enhanced from previous editions, with new content and no loss of original content. All of the earlier editions and versions of CMB will be retired from the UWM Digital Commons after May 31, 2019. But they will still be available by request directly from the author (firstname.lastname@example.org). We hope that you will like the improvements and that you will find CMB3e as useful as the earlier editions. Remember, we welcome all comments that will help us improve the iText for the next release.
