| accuracy and precision lab answer key: Teaching Undergraduate Science Linda C. Hodges, 2023-07-03 This book is written for all science or engineering faculty who have ever found themselves baffled and frustrated by their undergraduate students’ lack of engagement and learning. The author, an experienced scientist, faculty member, and educational consultant, addresses these issues with the knowledge of faculty interests, constraints, and day-to-day concerns in mind. Drawing from the research on learning, she offers faculty new ways to think about the struggles their science students face. She then provides a range of evidence-based teaching strategies that can make the time faculty spend in the classroom more productive and satisfying.Linda Hodges reviews the various learning problems endemic to teaching science, explains why they are so common and persistent, and presents a digest of key ideas and strategies to address them, based on the research she has undertaken into the literature on the cognitive sciences and education. Recognizing that faculty have different views about teaching, different comfort levels with alternative teaching approaches, and are often pressed for time, Linda Hodges takes these constraints into account by first offering a framework for thinking purposefully about course design and teaching choices, and then providing a range of strategies to address very specific teaching barriers – whether it be students’ motivation, engagement in class, ability to problem solve, their reading comprehension, or laboratory, research or writing skills.Except for the first and last chapters, the other chapters in this book stand on their own (i.e., can be read in any order) and address a specific challenge students have in learning and doing science. Each chapter summarizes the research explaining why students struggle and concludes by offering several teaching options categorized by how easy or difficult they are to implement. Some, for example, can work in a large lecture class without a great expenditure of time; others may require more preparation and a more adventurous approach to teaching. Each strategy is accompanied by a table categorizing its likely impact, how much time it will take in class or out, and how difficult it will be to implement.Like scientific research, teaching works best when faculty start with a goal in mind, plan an approach building on the literature, use well-tested methodologies, and analyze results for future trials. Linda Hodges’ message is that with such intentional thought and a bit of effort faculty can succeed in helping many more students gain exciting new skills and abilities, whether those students are potential scientists or physicians or entrepreneurs. Her book serves as a mini compendium of current research as well as a protocol manual: a readily accessible guide to the literature, the best practices known to date, and a framework for thinking about teaching. |

When a scientific effort fails to independently confirm the computations or results of a previous study, some fear that it may be a symptom of a lack of rigor in science, while others argue that such an observed inconsistency can be an important precursor to new discovery. Concerns about reproducibility and replicability have been expressed in both scientific and popular media. As these concerns came to light, Congress requested that the National Academies of Sciences, Engineering, and Medicine conduct a study to assess the extent of issues related to reproducibility and replicability and to offer recommendations for improving rigor and transparency in scientific research. Reproducibility and Replicability in Science defines reproducibility and replicability and examines the factors that may lead to non-reproducibility and non-replicability in research. Unlike the typical expectation of reproducibility between two computations, expectations about replicability are more nuanced, and in some cases a lack of replicability can aid the process of scientific discovery. This report provides recommendations to researchers, academic institutions, journals, and funders on steps they can take to improve reproducibility and replicability in science. |

| accuracy and precision lab answer key: Evaluating Measurement Accuracy Semyon G Rabinovich, 2013-07-03 “Evaluating Measurement Accuracy, 2nd Edition” is intended for those who are concerned with measurements in any field of science or technology. It reflects the latest developments in metrology and offers new results, but is designed to be accessible to readers at different levels: scientists who advance the field of metrology, engineers and experimental scientists who use measurements as tool in their professions, students and graduate students in natural sciences and engineering, and, in parts describing practical recommendations, technicians performing mass measurements in industry, quality control, and trade. This book presents material from the practical perspective and offers solutions and recommendations for problems that arise in conducting real-life measurements. This new edition adds a method for estimating accuracy of indirect measurements with independent arguments, whose development Dr. Rabinovich was able to complete very recently. This method, which is called the Method of Enumeration, produces estimates that are no longer approximate, similar to the way the method of reduction described in the first edition removed approximation in estimating uncertainty of indirect measurements with dependent arguments. The method of enumeration completes addressing the range of problems whose solutions signify the emergence of the new theory of accuracy of measurements. A new method is added for building a composition of histograms, and this method forms a theoretical basis for the method of enumeration.Additionally, as a companion to this book, a concise practical guide that assembles simple step-by-step procedures for typical tasks the practitioners are likely to encounter in measurement accuracy estimation is available at SpringerLink. |

| accuracy and precision lab answer key: Practical Instrumental Analysis Sergio Petrozzi, 2012-09-24 This practical book in instrumental analytics conveys an overview of important methods of analysis and enables the reader to realistically learn the (principally technology-independent) working techniques the analytical chemist uses to develop methods and conduct validation. What is to be conveyed to the student is the fact that analysts in their capacity as problem-solvers perform services for certain groups of customers, i.e., the solution to the problem should in any case be processed in such a way as to be fit for purpose. The book presents sixteen experiments in analytical chemistry laboratory courses. They consist of the classical curriculum used at universities and universities of applied sciences with chromatographic procedures, atom spectrometric methods, sensors and special methods (e.g. field flow fractionation, flow injection analysis and N-determination according to Kjeldahl). The carefully chosen combination of theoretical description of the methods of analysis and the detailed instructions given are what characterizes this book. The instructions to the experiments are so detailed that the measurements can, for the most part, be taken without the help of additional literature. The book is complemented with tips for effective literature and database research on the topics of organization and the practical workflow of experiments in analytical laboratory, on the topic of the use of laboratory logs as well as on writing technical reports and grading them (Evaluation Guidelines for Laboratory Experiments). A small introduction to Quality Management, a brief glance at the history of analytical chemistry as well as a detailed appendix on the topic of safety in analytical laboratories and a short introduction to the new system of grading and marking chemicals using the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), round off this book. This book is therefore an indispensable workbook for students, internship assistants and lecturers (in the area of chemistry, biotechnology, food technology and environmental technology) in the basic training program of analytics at universities and universities of applied sciences. |

| accuracy and precision lab answer key: Million Dollar Data: Building Confidence – Vol.1 Stephen DeMeo, 2020-07-31 Global warming, our current and greatest challenge, is without precedent. Among the many consequences that are impacting our society, one unanticipated concern involves scientific truth. When the President of the United States, and others in his administration, declare that global warming is fake science, it calls into question what real science is and what real school science should be. I will argue that real science is quality science, one that is based on the rigorous collection of reliable and valid data. To collect quality data requires bending over backwards to get things right, and this is exactly what makes science so special. Truth is made when scientists go this extra yard and devise controlled experiments, collect large data sets, confirm the data, and rationally analyze their results. Making scientific truth sounds difficult to do in the science laboratory, but in reality, there are many straightforward ways that truth can be constructed. In the first of two volumes, I discuss twelve such ways – I call them Confidence Indicators – that can allow students to strongly believe in their data and their subsequent results. Many of these methods are intuitive and can be used by young students on the late elementary level all the way up to those taking introductory college science courses. As in life, science is not without doubt. In the second volume I introduce the concept of scientific uncertainty and the indicators used to calculate its magnitude. I will show that science is about connecting confidence with uncertainty in a specific manner, what I refer to as the Confidence-Uncertainty Continuum expression. This important relationship epitomizes the scientific enterprise as a search for probabilistic rather than absolute truth. This two-volume set will contain a variety of ways that data quality can be instituted into a science curriculum. To support its use, many of the examples that I will present involve science teachers as well as student work and feedback from different grade levels and in different scientific disciplines. Specific chapters will be devoted to reviewing the academic literature on data quality as well as describing my own personal research on this important but often neglected topic. |

| accuracy and precision lab answer key: Laboratory Methods in Dynamic Electroanalysis M. Teresa Fernández Abedul, 2019-10-13 Laboratory Methods in Dynamic Electroanalysis is a useful guide to introduce analytical chemists and scientists of related disciplines to the world of dynamic electroanalysis using simple and low-cost methods. The trend toward decentralization of analysis has made this fascinating field one of the fastest-growing branches of analytical chemistry. As electroanalytical devices have moved from conventional electrochemical cells (10-20 mL) to current cells (e.g. 5-50 mL) based on different materials such as paper or polymers that integrate thick- or thin-film electrodes, interesting strategies have emerged, such as the combination of microfluidic cells and biosensing or nanostructuration of electrodes. This book provides detailed, easy procedures for dynamic electroanalysis and covers the main trends in electrochemical cells and electrodes, including microfluidic electrodes, electrochemical detection in microchip electrophoresis, nanostructuration of electrodes, development of bio (enzymatic, immuno, and DNA) assays, paper-based electrodes, interdigitated array electrodes, multiplexed analysis, and combination with optics. Different strategies and techniques (amperometric, voltammetric, and impedimetric) are presented in a didactic, practice-based way, and a bibliography provides readers with additional sources of information. - Provides easy-to-implement experiments using low-cost, simple equipment - Includes laboratory methodologies that utilize both conventional designs and the latest trends in dynamic electroanalysis - Goes beyond the fundamentals covered in other books, focusing instead on practical applications of electroanalysis |
