NOS captures issues about what characterizes the research process as well as the scientific knowledge. Here we, in line with a broad body of literature, use a wide definition of NOS including also e.g. Published socio-cultural aspects. It is argued that NOS issues, for a number of reasons, should be included in the teaching of science/physics. Research shows that NOS should be taught explicitly. There are plenty of suggestions on specific September and separate NOS activities, but the necessity of discussing NOS issues in connection to specific science/physics content and to laboratory work, is also 5 highlighted. In this article we draw on this body of literature on NOS and science teaching, and discuss how classroom situations in secondary physics classes could be turned into NOS-learning situations. The discussed situations have been suggested by secondary teachers, during in-service teacher training, as situations from every-day physics teaching, from which NOS could be highlighted. 1. The relevance of ‘nature of science’ look like? What is the role of experiments? Is the perspectives for science/physics teaching research process objective and rational, or are there also subjective and creative elements? How How certain is scientific knowledge?

They are critical but time-consuming in research and decision making for various disciplines. When conducting a review, a large volume of data is usually generated from relevant studies. Computer-based tools are often used to manage such data and to support the systematic review process. This paper describes a comprehensive analysis to gather the required features of a systematic review tool, in order to support the complete evidence synthesis process. We propose a framework, elaborated by consulting experts in different knowledge areas, to evaluate significant features and thus reinforce existing tool capabilities. The framework will be used to enhance the currently available functionality of CloudSERA, a cloud-based systematic review Citation: Person, T.; Ruiz-Rube, I.; Mota, J.M.; Cobo, M.J.; Tselykh, A.; tool focused on Computer Science, to implement evidence-based systematic review processes in Dodero, J.M.

  • Mothers in Science
    The aim of this book is to illustrate, graphically, that it is perfectly possible to combine a successful and fulfilling career in research science with motherhood, and that there are no rules about how to do this. On each page you will find a timeline showing on one side, the career path of a research group leader in academic science, and on the other side, important events in her family life. Each contributor has also provided a brief text about their research and about how they have combined their career and family commitments. This project was funded by a Rosalind Franklin Award from the Royal Society 1 Foreword It is well known that women are under-represented in careers in These rules are part of a much wider mythology among scientists of science. In academia, considerable attention has been focused on the both genders at the PhD and post-doctoral stages in their careers. paucity of women at lecturer level, and the even more lamentable The myths bubble up from the combination of two aspects of the state of affairs at more senior levels. The academic career path has academic science environment. First, a quick look at the numbers a long apprenticeship. Typically there is an undergraduate degree, immediately shows that there are far fewer lectureship positions followed by a PhD, then some post-doctoral research contracts and than qualified candidates to fill them.

  • How Science Works
    PB 1 How science works The Scientific Method is traditionally presented in the first chapter of science text- books as a simple recipe for performing scientific investigations. Though many use- ful points are embodied in this method, it can easily be misinterpreted as linear and “cookbook”: pull a problem off the shelf, throw in an observation, mix in a few ques- tions, sprinkle on a hypothesis, put the whole mixture into a 350° experiment—and voila, 50 minutes later you’ll be pulling a conclusion out of the oven! That might work if science were like Hamburger Helper®, but science is complex and cannot be re- duced to a single, prepackaged recipe. The linear, stepwise representation of the process of science is simplified, but it does get at least one thing right. It captures the core logic of science: testing ideas with evidence. However, this version of the scientific method is so simplified and rigid that it fails to accurately portray how real science works. It more accurately describes how science is summarized after the fact—in textbooks and journal articles—than how sci- ence is actually done. The simplified, linear scientific method implies that scientific studies follow an unvarying, linear recipe. But in reality, in their work, scientists engage in many different activities in many different sequences. Scientific investigations often involve repeating the same steps many times to account for new information and ideas. The simplified, linear scientific method implies that science is done by individual scientists working through these steps in isolation. But in reality, science depends on interactions within the scientific community.

General Philosophy of Science II. History of Philosophy of Science III. Special Topics a. Philosophy of Physics b. Philosophy of Biology c. Philosophy of Mind / Cognitive Science d. Logic and Foundations of Mathematics Students are required to answer a total of three questions from sections I and II (at least one from each section), and one question from section III. For each section, we have provided a list of core readings—mostly journal articles and book chapters—that are representative of the material with which we expect you to be familiar. Many of these readings will already be familiar to you from your coursework and other reading. Use this as a guide to filling in areas in which you are less well- prepared. Please note, however, that these readings do not constitute necessary or sufficient background to pass the comp. The Philosophy of Science area committee assumes that anyone who plans to write this exam has a good general background in the area acquired through previous coursework and independent reading.

  • The Universe As a Laboratory: Fundamental Physics
    The Universe as a Laboratory: Fundamental Physics The universe serves as an unparalleled laboratory for frontier physics, providing extreme conditions and unique opportunities to test theoretical models. Astronomical observations can yield invaluable information for physicists across the entire spectrum of the science, studying everything from the smallest constituents of mat- ter to the largest known structures. Astronomy is the principal player in the quest to uncover the full story about the origin, evolution and ultimate fate of the universe. The earliest “baby picture” of the universe is the map of the cosmic microwave background (CMB) radiation, predicted in 1948 and discovered in 1964. For years, physicists insisted that this radiation, seen coming from all directions in space, had to have irregularities in order for the universe as we know it to exist. These irregularities were not discovered until the COBE satellite mapped the radiation in 1992. Later, the WMAP satellite refined the measurement, allowing cosmologists to pinpoint the age of the universe at 13.7 billion years. Continued studies, including ground-based observations, seek to glean clues from the CMB about the basic nature of the universe and of its fundamental constituents. New telescopes and new technology promise to give astronomers better information about extremely distant objects—objects seen as they were in the early history of the universe. This, in turn, will provide valuable clues about how the first stars and galaxies developed and evolved into the objects we see in the universe today. The biggest mysteries in physics—and the biggest challenges for cosmologists—are the nature of dark matter and dark energy, which together constitute 95 percent of the universe.
