CELLS TEST FORM B (CHAPTER 4) 296 V ACKNOWLEDGEMENTS If I knew all about this one thing, wouldn't that be something... I am grateful for the support of my conceptual growth, which has been recognized as a developmental, life-long process of conceptual change by my professors at Iowa State University. Several have gone above and beyond their roles as instructors of content, serving as advisors, mentors and models of excellence, Chris Lubienski, David Owen, Mack Shelley, and my committee members, Tom Andre, Jackie Blount, Jim Colbert, Brian Hand, and Joanne Olson, to name a few. In particular, I am indebted to my major professor, Brian Hand, for providing an intellectual environment that could simply not have been topped. He has continually been an inspiration by being the one he is, consistently living his values; his actions aligned with his convictions. He modeled multiple forms of academic discourse in a respectful and non- threatening atmosphere, true to his culture. He ensured numerous opportunities to meet and work with premier scholars in the field, Vaughn Prain, Larry Yore, Carolyn Wallace, and Perry Klein, to name a few. I am also thankful for the interactions with each one of these professors, as they worked with me directly on research projects and/or provided thoughtful, constructive, comments on drafts. This kind of support is invaluable. Vaughn and Brian are masters of argumentation dialogue. Thus, the continual opportunities to engage with them in such discussions were the most formative of my educational experience to date. Brian also organized and structured research teams composed of individuals whose contributions and collaboration were essential to the work in this dissertation, Eun-mi Yang, Mark Williams, Jay Staker, Murat Gunel, Sozan Omar, Irene Grimberg, and Recai Akkus, to name a few. I am grateful for each one of these individuals, vi as our discussions and interactions have "stimulated thinking" about education in its fullest sense. Allison Donaldson, Nancy Wirth, and Judy Weiland made the process of navigating the university system a manageable and painless experience. Nancy and Allison shared their knowledge on numerous occasions. They added both style and grace to events that, had I been left to my own devices would not have been nearly as elegant. In addition, appreciation is extended to those at The Ohio State University, Doug Owens, Xiao-dong Lui, Arthur White, Karen Irving, Karen Zuga, Michael Scott, and Anita Roychoudhury whose advice and encouragement helped me defeat the odds and finish. In writing the dissertation I became a bit solipsistic, immersed in solitude. Often I felt like a doppelgânger, a ghostly counterpart to my real self, walking among a separate, external reality rather than existing within it. It is those who lay in wait for the return, my friends (esp. Suzanne Allen, Lisa Allen, & Kirsty Gane), family (esp. Lecil & Rita Hohenshell), and faithful canine companions, Leah and Sister Suzan, who most deserve appreciation. Their patience, support, encouragement, reassurance, and unconditional love are gifts so essential, it is the attempt to express this sentiment that makes me realize the true limitations of language. There are simply no words to convey the extent of my gratitude. To the force beyond the realm of science, may the arrogance and in particular, the selfishness this work represents subside. If I have achieved some level of success in coherently communicating some general understanding of what for me is largely still developing, I am grateful for the time I was afforded to construct and represent this. As with Emig, "writing is self-rhythmed. One writes best as one 1earns best, at one's own pace" (1977, p. 126). 1 CHAPTER 1. GENERAL INTRODUCTION Authors and researchers working within the writing-to-leam movement suggest that language creates, describes and reflects existing ideas and understandings (Keys, 1999b; Halliday & Martin, 1993; Lemke, 1990). For the writer, the act of writing promotes attainment of personal meaning, processing skills, requires thinking, and offers an opportunity for reflection on content (Applebee, 1984). Through writing, a student can demonstrate significant effort and communicate understanding of content. However, the promises of writing as powerful learning mode are manifold; and the practices and strategies used to reach such potential, appear to be equally as complex. The purposes of the enclosed papers were to reveal some of these dimensions, and make modest empirical contributions to a growing research base, which seeks to advance understanding of some of these dimensions. Introduction Recent editions of instructional texts for science teachers encourage the use of a variety of writing tasks, but provide little to no guidance or direction, presuming that students have the rhetorical knowledge and procedural strategies to succeed in writing and learning by engaging in these types of tasks. Literacy may imply a need to write (Norris & Phillips, 2003); however, alternative conceptions exist concerning what literacy in science means (Laugksch, 2000). While there are various models describing the cognitive

  • Teaching Scientific Literacy Through a Science Technology and Society Course: Prospective Elementary Science Teachers’ Case
    The Turkish Online Journal of Educational Technology – TOJET October 2004 ISSN: 1303-6521 volume 3 Issue 4 Article 8 TEACHING SCIENTIFIC LITERACY THROUGH A SCIENCE TECHNOLOGY AND SOCIETY COURSE: PROSPECTIVE ELEMENTARY SCIENCE TEACHERS’ CASE Dr. Esra MACAROGLU AKGUL Ataturk Faculty Of Education Marmara University, Goztepe Campus Istanbul-Turkey e-address: [email protected] phone: 05365268728 (mobile) mail address: Mandıra Cad. Onay Sitesi 3. blok D:3 Merdivenkoy 34732 Istanbul-Turkey ABSTRACT The study examines Turkish pre-service elementary science teachers’ scientific literacy levels. The research took place in Marmara University, in 2001-2002 academic year. The research participants were twenty randomly chosen students among all senior classes of the university mentioned above. The research data were gathered with the documents, i.e. class assignments and activities, collected in science-technology and society course performance portfolios. Interviews with students and field notes from the class were used for data triangulation. Participants’ definitions of scientific literacy were determined with document analysis and open coding of data. Then, assertions to explain findings were formed. The assertions displayed that participants define scientific literacy in relation with thinking and inquiry. However; they are having problems to define the term scientific. Documents displayed that although participants had some traditional understandings about science, they hold more contemporary views about scientific literacy. INTRODUCTION Almost all developing and developed countries have the purpose of increasing scientific literacy level of public among their educational goals. This purpose also takes place in Turkish educational agenda. The first step to reach that purpose is to define scientific literacy. There is no consensus on the definition of scientific literacy concept in literature.

The method of this paper is research note paper, with a literature review of research journals about scientific literacy in science learning. The Curriculum 2013 has emphasized scientific literacy on the learning process by suggesting the utilize of the scientific approach. The scientific approach provides an opportunity for students to perform contextual learning, therefore the learning experiences that students got becomes more meaningful. The scientific approach provides an opportunity for students to connect between the previous concept, the concept being studied and its relationship with other materials that are expected able to improve the scientific literacy of students. The scientific approach to learning science developed from the scientific method commonly known as the science process skills.

  • The Crisis of the “Public Understanding of Science” in Great Britain
    JCOM 2 (1), March 2003 The crisis of the “Public Understanding of Science” in Great Britain Nico Pitrelli Master’s Degree Course in Scientific Communication – ISAS – Trieste – Italy Introduction In a brief article published by Science1 last October, British scientists stated that the expression “Public Understanding of Science”(PUS), which was traditionally employed in Anglosaxon societies to refer to the issue of the relationship between science, technology and society, is out-of-date. It should be replaced by “Public Engagement with Science and Technology” (PEST), a new acronym that clearly invites to reconceptualise the relationship between science and the public. The new approach involves the engagement of the public – or rather the publics – of science, through dialogue, in particular through an open and equal-to-equal discussion between scientists and non-experts that would enable non-experts to become the actual protagonists in the scientific decisions producing social effects. It is not just a matter of terminology. The shift from merely promoting the understanding of science – as indicated by PUS – to emphasising the need for public engagement is seen as necessary to obtain public confidence in science. Indeed, there is a general perception that public opinion is increasingly losing confidence in science. However, the initiative of the British researchers does not stand alone. In the last few years politicians, scientists, scholars and media operators in the UK have been insisting 1 “From PUS to PEST”, Science, vol. 298, 4th October 2002, p.49 1 on revising the role of the public in PUS communication theories and practice2,3,4,5,6,7.

  • Assessing Scientific Literacy Levels Among Secondary School Science Students of District Lahore
    Bulletin of Education and Research December 2020, Vol. 42, No. 3 pp. 1-21 Assessing Scientific Literacy Levels among Secondary School Science Students of District Lahore Iram Shahzadi* and Abida Nasreen** __________________________________________________________________ Abstract The purpose of this quantitative study was to assess the scientific literacy levels among the government secondary school science students of district Lahore. Proportionate stratified random sampling and purposive sampling were used for selection of 16 government secondary schools comprised of seven boys’ and nine girls’ schools of district Lahore. The selected schools were taken by five percent of proportion of total population. By using Bybee Scale, the test was designed contained two to ten contextual situations and questions of four scientific literacy levels. Analysis of the study was based on percentage, mean, t-test, and ANOVA. The results revealed that secondary school science students attained the nominal and functional level of scientific literacy which was at the lowest levels. Findings also showed that girls performed better than boys in all levels of scientific literacy. There was no difference in the scores of students related to their mothers’ education and mothers’ skill level. There was a difference in the scores of students related to their fathers’ education, fathers’ skill level and students’ dedicated time for learning of science (hours per day, at school as well as at home). The curriculum developers should plan a course of scientific literacy or merge scientific literacy concepts and activities in science textbooks for secondary schools to increase scientific literacy. The time period for science subjects should be increased in government schools.

While most undergraduate construction curricula are designed to improve SL, no recent study was found to have assessed undergraduate construction students’ SL skills. Therefore, the purpose of this research was to assess the SL attitudes, skills, and self-efficacy of 46 undergraduate construction students. Data was obtained through students’ completion of the standard 28-item Test of Scientific Literacy Skills (TOSLS) instrument; a student self-reporting SL self-efficacy survey; and focus group discussions.

Collier Thesis submitted to the Faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE in Science and Technology Studies APPROVED: Y— Joseph C. Pitt, Chair Aone ble EtaaT hone, Steve Fuller Elisworth Fuhrman April, 1993 Blacksburg, VA LD S635 VE5S , DaQa cose} aM’~ Scientific Discourse, Sociological Theory, and the Structure of Rhetoric James H. Collier Graduate Program in Science and Technology Studies Chair: Joseph C. Pitt (ABSTRACT) This thesis examines the rhetorical, analytical and critical efficacy of reflexivity and sociological theory as means for reconciling the normative and descriptive functions of the rhetoric of science. In attempting to define a separate research domain within Science Studies, rhetoric of science has borrowed Strong Program and constructivist principles and descriptions of scientific practice from the Sociology of Scientific Knowledge (SSK) as a basis for analyzing scientific discourse. While epistemological claims in the social sciences have been considered inherently self-referential and subject to reflexive analysis and critique, rhetoricians have generally taken these claims on face value and applied them to a treatment of scientific practice. Accordingly, rhetoricians have maintained a natural ontological attitude to sociological theories and descriptions supporting an understanding of scientific discourse as implicitly rhetorical. Recently, however, the concept of "rhetoric" in rhetoric of science has come under scrutiny. This thesis will connect arguments involving the relation of the "irreducibly social" nature of science, to a concept of scientific discourse as rhetorical "without remainder,” to the philosophical commitments of reflexive analysis.

  • Inquiry and Scientific Literacy
    1 Inquiry and Scientific Literacy WHat IS ScieNce? 1 How do you define science? How do you think your students define science, or how would they describe a scientist? Not too long ago, we had a group of seventh-grade students draw scientists. Overwhelmingly, the pictures depicted men (some with Einstein-like hair) standing behind lab tables using flasks or test tubes. The average person might define science as a body of scientific knowledge. Philosophers may regard science as a means to obtain the truth through questioning, while scientists probably see science as a means of exploring a hypothesis by following a set of procedures. In a classroom, the teacher may encourage students to think of science as problem solving, obser- vation and description of the real world, discovery, seeking the truth, studying nature, turning facts into theories, organizing knowledge, using logic, or study- ing the universe. While all of these statements have a connection with science, each is only a part of science—only when they are put together do they begin to represent science. Science is learning about the world. All dimensions of science rather than an emphasis on only science content, support this learning. Knowledge is obtained through observations and investigations that can be substantiated by others. According to the National Research Council (NRC; 1999), explanations that cannot be based on empirical evidence are not part of science. Science is one subject that encourages concrete action (Wright & Wright, 1998). There are three aspects of science knowledge for which scientists are responsible—understand, explain, and apply. Careful observations, designed experimentation, and logical reasoning can accomplish these aspects.

  • Attitudes Toward Science and Scientific Literacy Among Romanian Young Adults
    ERD 2016: Education, Reflection, Development, Fourth Edition Attitudes toward Science and Scientific Literacy Among Romanian Young Adults Barz Daniela-Luminițaa* * Corresponding author: Barz Daniela-Luminița, [email protected] aPhD Candidate,”Iuliu Hațieganu” University of Medicine and Pharmacy Cluj-Napoca, 8 Babeş Street, Cluj-Napoca, Romania Abstract http://dx.doi.org/10.15405/epsbs.2016.12.7 The paper explores attitudes toward science and scientific literacy among Romanian young adults, through an online survey following key dimensions - attitudes toward science, integration of science in everyday life, beliefs in pseudoscientific phenomena and knowledge of the scientific method. Moreover, the study focuses especially on healthcare students and professionals’ scientific literacy, exploring the level of scientific reasoning within the medical field. Analysis includes multiple comparisons across different fields of study, professional areas and age groups. The novelty of the study consists in shifting the assessment of scientific literacy from general scientific knowledge toward the understanding of the scientific method. Results of the present study confirmed a deficit in scientific knowledge, but more importantly, demonstrated that the relationship between scientific literacy and attitudes toward science was a non-linear one. In fact, the study found a gap between what people accept to be scientific fact and what they choose to integrate into everyday life. Given these results, we argue that science education’s focus should be on developing scientific reasoning rather than providing scientific knowledge. © 2016 Published by Future Academy www.FutureAcademy.org.uk Keywords: Attitudes toward science; scientific literacy; higher education; medical education. 1. Introduction Scientific literacy refers to an understanding of science and technology, of the scientific process and scientific facts.

Be sure to answer as many of the questions as you can in the time allotted. You will receive attendance points for completing the entire assignment today. Your grade will depend on completeness and thoroughness, not on correct answers. But, try your best, your honest answers will help us better prepare the materials for the remainder of the semester. Mark your answers on the scantron sheet. Bubble in your #ID on your scantron. Do NOT use a calculator. Thank you for your participation in this project! 1. Which of the following is a valid scientific argument? a. Measurements of sea level on the Gulf Coast taken this year are lower than normal; the average monthly measurements were almost 0.1 cm lower than normal in some areas. These facts prove that sea level rise is not a problem. b. A strain of mice was genetically engineered to lack a certain gene, and the mice were unable to reproduce. Introduction of the gene back into the mutant mice restored their ability to reproduce. These facts indicate that the gene is essential for mouse reproduction. c. A poll revealed that 34% of Americans believe that dinosaurs and early humans co-existed because fossil footprints of each species were found in the same location. This widespread belief is appropriate evidence to support the claim that humans did not evolve from ape ancestors. d. This winter, the northeastern US received record amounts of snowfall, and the average monthly temperatures were more than 2°F lower than normal in some areas.
