  • Testing and Evaluation in the Biological Sciences
    REPORT OF THE PANEL ON EVALUATION AND TESTING NOVEMBER 1967/CUEBS Publication 20 TESTING AND EVALUATION IN THE BIOLOGICAL SCIENCES COMMISSION ON UNDERGRADUATE EDUCATION IN THE BIOLOGICAL SCIENCES This book is a wonderful resource but had only a limited distribution back around 1967. Thanks to GWU for permission to put it in digital form so that it can be shared widely. It is still under copyright, so please read the permission letter. Biology has changed quite a bit since 1967, so many of the example questions are dated and this book doesn’t serve as a simple question bank. Yet the questions can be very useful as exemplars of questions pointed at different topics and at different cognitive levels. Since you have the digital version, it is fairly easy to copy/paste them and then update/modify as you find appropriate and useful. While I did a lot of proofreading, I’m sure I’ve missed many details, so the scanned pages in jpg format are also available. Feel free to check them if anything puzzling is found. To me, the question bank emphasizes the value of the earlier discussion in the book about assessment and evaluation methods. While most of the items given are multiple choice questions, there is also presentation and discussion about essay and matching questions. Each question, of all types, has an associated cognitive level (using Bloom’s Taxonomy). This significantly assists the instructor in assessing the progress of the students, and there is also discussion of evaluating the validity of the questions. For courses in other areas than Biology, this book can also be valuable.

  • LABORATORY INQUIRY Part 2 – Practicing Procedures and Developing Your Research Project
    LABORATORY INQUIRY Part 2 – Practicing Procedures and Developing Your Research Project I. Researching Mitosis and Cellular Function For this research project, your team should choose some aspect of mitosis, and attempt to determine the function of a particular cellular structure or molecule in the mitotic process. To give you an idea about how to proceed, we provide the following section outlining an example project in which the role of the spindle fibers in mitosis is investigated. Your team should use this type of approach to analyze a different structure or phenomenon that occurs during mitosis. A. Example Project: The Role of Spindle Fibers in Mitosis Introduction: Structure and Function of Spindle Fibers Spindle fibers play an important role throughout the mitotic process. For example, late prophase is characterized by movement of the mitotic spindle to opposite ends of the cell. In metaphase, sister chromatids become visibly associated with spindle fibers attached at each pole of the cell. Spindle fibers pull sister chromatids apart during anaphase, and then disassemble at telophase. The spindle fibers contain a highly organized array of microtubules which are long, hollow, unbranched tubes composed of globular proteins. Microtubules are also components of other cellular structures, including the cytoskeleton, and they form the core of both cilia and flagella. Microtubules are not only involved in separating chromosomes during mitosis and meiosis, but also function as structural supports and organizers for cells. In plant cells, for example, microtubules maintain cell shape through their influence on the formation of the cell wall during interphase. Studies also showed that microtubules play a role in maintaining the internal organization of cells and are responsible for intracellular motility of macromolecules and organelles.
