Robinson, Ian, Robinson, Saul, and Robinson, Nathan
- Abstract
Described here is a well established opensource geophysics project to monitor atmospheric infrasound 24/7. It employs a modern digital, I[superscript 2]C enabled differential pressure sensor--unlike the older analog devices more commonly used. Python software automatically uploads plots whilst data is stored in standard ".mseed" format for further analysis. Very open-ended with lots of opportunities for students of all levels, schools and above, to redesign and test replacement components. This is real science, in a little studied area. The equipment required is relatively cheap and offers many opportunities for students to build and refine a sensing system of research quality. It may be of interest as a national school's network producing results of real scientific and educational value at little cost.

4. Every Equation Tells a Story: Using Equation Dictionaries in Introductory Geophysics
- Author
-
Caplan-Auerbach, Jacqueline
- Abstract
Many students view equations as a series of variables and operators into which numbers should be plugged rather than as representative of a physical process. To solve a problem they may simply look for an equation with the correct variables and assume it meets their needs, rather than selecting an equation that represents the appropriate physical process. These issues can be addressed by encouraging students to think of equations as stories, and to describe them in prose. This is the goal of the Equation Dictionary project, used in Western Washington University's introductory geophysics course. Throughout the course, students create personal dictionaries consisting of (a) the equation itself, (b) a brief description of variables, (c) a prose description of the physical process described by the equation, and (d) additional notes that help them understand the equation. In writing these definitions students learn that equations are simplified descriptions of physical processes, and that understanding the process is more useful than memorizing a sequence of variables. Dictionaries also serve as formula sheets for exams, a task that encourages students to write meaningful, organized definitions. Furthermore, instructor review of the dictionaries is an excellent way to identify student misconceptions and learn how well they understand derivations and lectures.

6. Shaking It Up
- Author

Lund, Alana, Roemmele, Christopher, Roetker, Lisa, and Smith, Steven
- Abstract
The study of earthquakes can help students build connections between theoretical analysis and real-world applications. However, units on earthquakes typically struggle to bridge that gap between theory and application. Traditional class activities focus on measuring earthquakes, such as triangulating epicenters by analyzing P and S wave arrival times (see sidebar, p. 38) or using wave amplitudes to calculate Richter magnitudes. STEM-based activities take another step by adding a community-minded perspective. Such lessons often involve shaking models of buildings to measure resonance or using the Mercalli Intensity Scale (see sidebar, p. 38) to quantify structural damage and human responses. Such lessons, though valuable, limit students to analysis without action, leaving them to wonder how their results might be applied. This article describes a lesson in which students act on their analyses by determining emergency response priorities in a theoretical earthquake disaster scenario. The students step into the shoes of engineers to analyze data from a variety of sources to make critical decisions for their community.

7. Nurturing Minority Adolescents' Giftedness through Facilitating Individual 'Voice'.
- Author

Haensly, Patricia A. and Lehmann, Patricia
- Abstract
This paper describes how a geosciences summer program for 50 Hispanic and Black eighth graders with high potential from at-risk backgrounds, planned and executed activities designed to empower these youth by teaching them strategies to develop effective "voice," while concurrently nurturing abilities and inspiring significant career aspirations. To have "voice" is defined as being able to express and test ideas, beliefs, and attitudes with a responsive audience with assurance that others are listening and perceiving the person as credible, with potential to affect decisions and outcomes favorable to the ideas, beliefs, and attitudes expressed. Specific program strategies designed to achieve these goals included: (1) a period of each day assigned to a brief journal writing session, in which the youth were expected to respond to the prompt of the day that related to science or math growth, specific experiences in the environmental science curriculum, and personal growth, feelings and attitudes; (2) peer interaction among the youth, who were from six different school/urban sites, promoted through team-based geoscience field experiences and problem solving, and through leisure activities; and (3) relaxation and leisure group activities, as well as evening discussion sections, guided by camp staff and the director. The personal attention of caring teachers was, perhaps, the lynch pin that made all of the strategies planned so successful that without exceptions campers left expressing in various ways that this summer month was one of the most important experiences of their lives to date.

8. Seismic Sleuths. Earthquakes: A Teacher's Package for Grades 7-12.
- Author
-
American Geophysical Union, Washington, DC.
- Abstract
This teacher package for grades 7-12 takes a broad approach in preparing students for earthquakes. "Hands-on/minds-on", inquiry-driven activities are balanced by library research and visits with disaster planning officials. Emphasis is placed on cooperative learning and the constructivist approach to teaching. Students not only study the causes of earthquakes but also study building construction and forces that damage buildings, then construct model buildings to test their knowledge. Students explore how their community prepares for emergencies and how it is empowered with tools to bring about change in community disaster preparedness. Some activities are interdisciplinary. Each unit section contains an overview of the contents and package layout. Each unit in turn has an introduction that gives specific information on the unit content. Lessons and activities include complete procedures, material lists, and master pages for the students. Unit 1 contains the introduction that serves as a foundation for the other units by pre-assessing student knowledge of earthquakes and hazards preparedness. Unit 2 covers causes of earthquakes, geologic time, and side effects of earthquakes. Unit 3 explores the science and history of seismology. Unit 4 covers building design and how earthquake forces act on various designs. Unit 5 focuses student attention on earthquake preparedness. Unit 6 offers a variety of summative and assessment activities. (PVD)

11. Reaching Students: What Research Says about Effective Instruction in Undergraduate Science and Engineering
- Author
-
Kober, Nancy and Kober, Nancy
- Abstract
The undergraduate years are a turning point in producing scientifically literate citizens and future scientists and engineers. Evidence from research about how students learn science and engineering shows that teaching strategies that motivate and engage students will improve their learning. So how do students best learn science and engineering? Are there ways of thinking that hinder or help their learning process? Which teaching strategies are most effective in developing their knowledge and skills? And how can practitioners apply these strategies to their own courses or suggest new approaches within their departments or institutions? "Reaching Students" strives to answer these questions. "Reaching Students" presents the best thinking to date on teaching and learning undergraduate science and engineering. Focusing on the disciplines of astronomy, biology, chemistry, engineering, geosciences, and physics, this book is an introduction to strategies to try in your classroom or institution. Concrete examples and case studies illustrate how experienced instructors and leaders have applied evidence-based approaches to address student needs, encouraged the use of effective techniques within a department or an institution, and addressed the challenges that arose along the way. The research-based strategies in "Reaching Students" can be adopted or adapted by instructors and leaders in all types of public or private higher education institutions. They are designed to work in introductory and upper-level courses, small and large classes, lectures and labs, and courses for majors and non-majors. And these approaches are feasible for practitioners of all experience levels who are open to incorporating ideas from research and reflecting on their teaching practices. This book is an essential resource for enriching instruction and better educating students.

12. Reading Instruments: Objects, Texts and Museums
- Author
-
Anderson, Katharine, Frappier, Melanie, Neswald, Elizabeth, and Trim, Henry
- Abstract
Science educators, historians of science and their students often share a curiosity about historical instruments as a tangible link between past and present practices in the sciences. We less often integrate instruments into our research and pedagogy, considering artefact study as the domain of museum specialists. We argue here that scholars and teachers new to material culture can readily use artefacts to reveal rich and complex networks of narratives. We illustrate this point by describing our own lay encounter with an artefact turned over for our analysis during a week-long workshop at the Canada Science and Technology Museum. The text explains how elements as disparate as the military appearance of the instrument, the crest stamped on its body, the manipulation of its telescopes, or a luggage tag revealed the object's scientific and political significance in different national contexts. In this way, the presence of the instrument in the classroom vividly conveyed the nature of geophysics as a field practice and an international science, and illuminated relationships between pure and applied science for early twentieth century geologists. We conclude that artefact study can be an unexpectedly powerful and accessible tool in the study of science, making visible the connections between past and present, laboratory and field, texts and instruments.

Mousa, W. A.
- Abstract
The purpose of this paper is to share the experience gained in, and the efforts made toward, introducing and implementing a new course in the challenging and important area of geophysical signal processing at the Electrical Engineering (EE) Department, King Fahd University of Petroleum and Minerals (KFUPM), Dhahran, Saudi Arabia. The new course, titled "Geo-Signal Processing," was offered both at the graduate level and as a special topics course to undergraduates. The course was developed in collaboration with the Earth Sciences Department at KFUPM. This paper contributes new information because it stresses the multidisciplinary aspects of digital signal processing (DSP) technologies when applied to estimating the Earth's layered structure on the basis of seismic data. Unlike many Earth sciences seismic data processing courses, this Geo-Signal Processing course also emphasizes that the perspective taken by those working in DSP is different from that taken by geophysicists. The course presents DSP with particular emphasis on seismic data signals and the artifacts accompanying them while covering the principles and algorithms needed for processing seismic signals in both deterministic and statistical fashion. Topics include, but are not limited to, basic seismic theory, acquisition of seismic data, analysis of seismic signals and noise, deterministic filtering of seismic data, and statistical processing of seismic data.

14. Using Google Earth to Teach Plate Tectonics and Science Explanations

Blank, Lisa M., Plautz, Mike, and Almquist, Heather
- Abstract
"A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas" emphasizes that the practice of science is inherently a model-building activity focused on constructing explanations using evidence and reasoning (NRC 2012). Because building and refining is an iterative process, middle school students may view this practice as tedious and fail to appreciate science as a creative endeavor. Digital tools such as Google Earth (GE) can help with this challenge, but many classroom applications of GE limit students to passive observation of pre-developed GE tours. The authors wondered how they could get their students to use GE as a scientist would--to view, explore, and create geospatial visualizations that advance scientific understanding. Consequently, they developed the Cyber-Enabled Earth Exploration Curriculum, which is described in this article. Using this curriculum, students progress from making simple observations in the GE environment to creating their own data files and overlays to evaluate and visualize data.

15. An Integrated, Problem-Based Learning Material: The 'Satellite' Module

Selcuk, Gamze Sezgin, Emiroglu, Handan Byacioglu, Tarakci, Mehmet, and Ozel, Mustafa
- Abstract
The purpose of this study is to introduce a problem-based learning material, the Satellite Module, that has integrated some of the subjects included in the disciplines of physics and mathematics at an introductory level in undergraduate education. The reason why this modular and problem-based material has been developed is to enable students to investigate a real-life problem, both in and outside the class, in a fictitious set of PBL scenarios where physics and mathematics subjects are integrated, and produce a relationship between the two prementioned fields of study. The longer version of the module was tested on 75 geophysics engineering students at Dokuz Eylul University during 2005-2006 academic year. The study is advisory as it has some limitations due to the fact that the PBL approach has not been compared to the classical teaching method where the subjects of physics and maths are instructed separately. Hence, the effectiveness of the approach suggested, such as the success of the course, transferring what has been learnt, should be investigated in further studies. (Contains 3 figures.)

- Abstract
Learn the astronomy behind the changing of the seasons. Students know that we mark the change of seasons with the position of the Sun over certain parts of the Earth. The specific time and date for the change of seasons is determined by the position of the Sun, not above the horizon necessarily, nor geographically, but rather where the Sun is using astronomical coordinates.

17. University Students' Explanatory Models of the Interactions between Electric Charges and Magnetic Fields
- Author

Saglam, Murat
- Abstract
This study aimed to investigate the models that co-existed in students' cognitive structure to explain the interactions between electric charges and uniform magnetic fields. The sample consisted of 129 first-year civil engineering, geology and geophysics students from a large state university in western Turkey. The students answered five diagnostic questions, testing their understanding of the interactions between electric charges and magnetic fields. For each question, the students had 100 points to divide between the options in order to indicate the ones that were attractive to them. The study found that many students possessed more than one model competing to explain the phenomenon in each question and they found these models plausible. This study provided further evidence that students' reasoning was context-dependent. However, employing teaching approaches like the learning cycle during the instruction might help students to grasp a more coherent understanding of the interactions between electric charges and magnetic fields. Encouraging students to use metacognitive strategies in science courses might help them to develop the habit of thinking about their thought. This, in turn, might reduce the adverse effects of the cues presented in questions on their reasoning. (Contains 2 tables.)

18. Students' Performance Awareness, Motivational Orientations and Learning Strategies in a Problem-Based Electromagnetism Course
- Author

Saglam, Murat
- Abstract
This study aims to explore problem-based learning (PBL) in conjunction with students' confidence in the basic ideas of electromagnetism and their motivational orientations and learning strategies. The 78 first-year geology and geophysics students followed a three-week PBL instruction in electromagnetism. The students' confidence was assessed through a diagnostic test on electromagnetism. The Motivated Strategies for Learning Questionnaire (MSLQ) was used to identify students' motivational orientations and learning strategies. The results indicate that many students were confident in incorrect answers, and had inadequate use of cognitive and metacognitive learning strategies. Providing students with some formative assessments during the PBL process could help them to better judge their understanding, which, in turn, would result in better student calibration (i.e., students would be more confident in their correct answers, and less confident in their incorrect answers) in electromagnetism. Helping the first-year PBL students to obtain effective cognitive and metacognitive learning strategies early in the academic year could improve their understanding of physics concepts.

Abbott, Cheryl and Swanson, Marc
- Abstract
A collaborating scientist--a rewarding addition to any high school science program--can help students collect and analyze data that either replicates or parallels the work of the partnering scientist. This type of partnership is beneficial for both students and scientists, and perhaps there has never been a better time to consider such a collaborative project. In this article, the authors present a scientist-student collaborative project developed by University of Alaska Fairbanks geophysicist Martin Jeffries together with a program that he developed called the Alaska Lake Ice and Snow Observatory Network (ALISON). This article examines the critical components of a successful collaborative scientist-student project. (Contains 2 figures.)

21. Difficult to Document: The History of Physics and Allied Fields in Industrial and Government Labs
- Author

Anderson, R. Joseph
- Abstract
Approximately thirty years ago archivists began formulating new models to guide archival collecting, creating a literature that continues to grow. In the mid-1980s, the introduction of the documentation strategy collection model put new emphasis on cooperation between repositories and among stakeholders. The model initially focused on the history of science, which has traditionally been poorly documented. Today, the documentation strategy model remains an essential tool in preserving the history of physics, astronomy, geophysics, and allied fields. The Center for History of Physics is using it to move beyond the records of academic science to develop strategies to preserve sources in the especially hard-to-document realms of government and corporate research.

Carnegie Institution of Washington, Washington, DC.
- Abstract
Various research studies designed to enhance knowledge about the earth's core are discussed. Areas addressed include: (1) the discovery of the earth's core; (2) experimental approaches used in studying the earth's core (including shock-wave experiments and experiments at high static pressures), the search for the core's light elements, the possible presence of potassium in the core, and use of the diamond cell for investigating the core; (3) seismic explorations of the core; (4) inhomogeneities at the core-mantle boundary; (5) terrestrial magnetism and the outer core; and (6) theories of inner-earth structure from the perspective of solar system history. Studies of the earth's mantle which may provide additional information about the earth's core are also discussed. They include laboratory experiments with mantle materials and modeling of mantle structure at the Carnegie Institution's Department of Terrestrial Magnetism. It is pointed out that although many questions about the earth's core are still unanswered, the promise of new research tools is vast. Favored by advances in computer modeling and in techniques for experiments at very high pressure, today's scientists seem well-positioned to address these questions about the deep earth. (JN)

- Abstract
The American Institute of Physics is working toward the development of a national information system for physics, whose objective is the organization of the flow of physics information from the producers to the users. The complete physics information system has several constituent subsystems, among which are: one for the management of the flow of primary information (documents), one for the generation of secondary information (abstracts, titles, indexes, etc.) and one for the improvement of the flow of tertiary information. This last is the result of the scholarly effort of evaluation and compaction of the primary information which becomes part of the storehouse of "Science Knowledge." The physics system is discipline-based in order to insure proximity to the producer; it will also couple with other discipline-based systems, with mission-based systems, and with disseminator institutions to fulfill the needs of its various potential users. This network of coupled information systems, institutions, and individuals, with its formal and informal links, when it is focused on physics producers and users, is the Network for Physics Information. This report outlines the anticipated characteristics and operations of the network and of various component systems. (Author)

American Inst. of Physics, New York, NY. Information Div. and Koch, H. William
- Abstract
The American Institute of Physics (AIP) publishes 87% of the primary research journals in the discipline of physics in the United States. These journals have provided an indispensable communication mechanism for research results and education in physics and astronomy. A redesign of the present journal system is required because of expansions in size, increased interdependences of science disciplines, higher expectations of physicists and reasonable availabilities of new technologies. Designing and phasing into a new system must be based on an understanding of the basic economics of the present system. Thus, the focus of this report is on the financial aspects of today's AIP publishing program with some preliminary thoughts on new, more user-oriented journals. (NH)

American Inst. of Physics, New York, NY. Information Div. and Koch, H. William
- Abstract
Science communication techniques are expected to change markedly in the next decade because of the developments on an international scale of coupled information systems in various scientific disciplines and technological missions. A change in techniques is also expected because of growing needs of users as well as of producers of science information. These changes will have profound effects on the principal formal mechanism of communication in the discipline of physics in the U.S.--the archival, primary research journal. The examination of possible changes in the role of U.S. journals reflects the financial and scientific experiences of the American Institute of Physics that publishes 87% of the primary research literature of U.S. physics literature and 35% of the world's physics literature. With financial support from the U.S. National Science Foundation, the Institute is undertaking the development of a National Information System for Physics that should provide scientists with more timely and facile access to the large well-organized central store of worldwide physics information. This access will be made possible by a variety of services and publications each responsive to the changing needs and interests of the many subdisciplines in the physics community. (Author/NH)
