Star Formation And Tidal Encounters With The Low Surface Brightness Galaxy Ugc 12695 And Companions, Stacy S. Mcgaugh

Faculty Scholarship

We present VLA H I observations of the low surface brightness (LSB) galaxy UGC 12695 and its two companions, UGC 12687 and a newly discovered dwarf galaxy 2333 + 1234. UGC 12695 shows solid-body rotation but has a very lopsided morphology of the H I disk, with the majority of the H I lying in the southern arm of the galaxy. The H I column density distribution of this very blue LSB galaxy coincides in detail with its light distribution. Comparing the H I column density of UGC 12695 with the empirical (but not well-understood) value of Σc = 1021 …

Department Of Fisheries Annual Report Highlights 1999 - 2000, Department Of Fisheries, Western Australia

Department of Fisheries Annual Reports

1999/2000 has marked a 'sea change' in fisheries management throughout Australia towards the principles of Ecologically Sustainable Development (ESD). This is a dynamic concept with an evolving framework that requires a balancing of social, economic and environmental considerations.

The principles of ESD - of using, conserving and enhancing the community's resources so that ecological processes, on which life depends, are maintained, and the total quality of fisheries, now and in the future, can be increased - are vital in a state, national and international context for Fisheries WA and its clients. Having fisheries that are governed under ESD principles is …

Portfolios And Performance Assessment: Tools For Changing Pedagogy With Pre-Service Mathematics Teachers, R. Welchman

Journal of Mathematics and Science: Collaborative Explorations

Portfolios serve many roles in the development of prospective teachers. Faculty at Brooklyn College found that portfolios can play two other important roles — as tools in faculty development and as a conduit in the development and description of college curriculum. Faculty came together to design a portfolio outline which both defined the introductory mathematics methods course and facilitated establishment of standards. The format was adapted for other populations, each time being modified to suit the new context.

Using Undergraduate Teaching Scholars In A Laboratory Course For Non-Science Majors, T. Jordan

Journal of Mathematics and Science: Collaborative Explorations

Although laboratory instruction for non-science majors is a major goal of higher education, its implementation is often difficult in practice. Non-science students are often uncomfortable with a laboratory environment and require close supervision for the laboratory instruction to be effective. To address this problem, support from the New York Collaborative for Excellence in Teacher Preparation (NYCETP) was used to recruit and train undergraduate Teaching Scholars to assist in the instructional laboratories of NYU’s core science program. The Teaching Scholar was paired with a graduate student laboratory instructor to create a “teaching team.” Responses on student evaluations show that the arrangement …

Using Evaluation To Foster Nycetp Goals: Case Studies And Intercampsus Collaboration, C K. Tittle, S. J. Pape, B. Flugman

Journal of Mathematics and Science: Collaborative Explorations

This article describes the use of case studies as part of the formative evaluation conducted for the New York Collaborative for Excellence in Teacher Preparation (NYCETP). While case studies are often conducted for evaluations by outside experts, consultants, or evaluators themselves, we developed a strategy for case studies that used NYCETP faculty to case-study each other. This strategy involved cross-campus collaboration and cross-discipline (Arts & Science and Education) collaboration, and thus actively supported one of the NYCETP goals. The case study strategy also included the development of a faculty (peer) review form for evaluation of documentation of new and revised …

Patterns In The Sand: Mathematical Exploration Of Chladni Patterns, A. M. Coughlin

Journal of Mathematics and Science: Collaborative Explorations

Chladni Patterns are formed when sand settles at the nodes of two dimensional standing waves, excited on a metallic plate which is driven at a resonant frequency. By considering a two-dimensional rectangular membrane with fixed boundary and constant density as an idealized model of the metal plate, a formula for predicting the Chladni Patterns that will form at certain frequencies can be found. In addition to mathematically exploring these mysterious patterns, I have created my own “Chladni Patterns” in the lab.

It's Fun, But Is It Science? Goals And Strategies In A Problem-Based Learning Course, M. S. Bruno, C. D. Jarvis

Journal of Mathematics and Science: Collaborative Explorations

All students at Hampshire College must complete a science requirement in which they demonstrate their understanding of how science is done, examine the work of science in larger contexts, and communicate their ideas effectively. Human Biology: Selected Topics in Medicine is one of 18-20 freshman seminars designed to move students toward completing this requirement. Students work in cooperative groups of 4-6 people to solve actual medical cases about which they receive information progressively. Students assign themselves homework tasks to bring information back for group deliberation. The goal is for case teams to work cooperatively to develop a differential diagnosis and …

The Impact Of A National Science Foundation Collaborative For Excellence In Teacher Preparation On An Undergraduate Chemistry Course For Non-Chemistry Science Majors, J. Tyson

Journal of Mathematics and Science: Collaborative Explorations

In 1999 and 2000 Chemistry 312: Analytical Chemistry for non-chemistry science majors (taken in the junior or senior year), was revised as a result of the instructor’s involvements in the Center for Excellence in Teacher Preparation project and an NSF equipment grant. Changes included the introduction of a K-12 teaching requirement, more emphasis on co-operative learning and on inquiry-based exercises. These latter two pedagogical practices had more impact on the laboratory activities than on the classroom activities. Students in the laboratory were assigned defined roles in the groups and all groups undertook a three-week research project. Students’ responses to the …

Integration Of Multimedia Interactive Web Tools With In-Class Active Learning, A. Ganz, K. Wongthavarawat, A. Phonphoem

Journal of Mathematics and Science: Collaborative Explorations

In this paper, we present our experience with an introduction to engineering course in which we used a combination of active and collaborative teaching methods, multimedia web-based material, and web-based interactive tools. The students were engaged in active learning in class with methods such as demonstrations, hands-on work, and group work. After class, the students used the web-based material that we developed, such as multiple choice quizzes, interactive applets, and animations. We have also developed a number of web-based course management tools that were used by the course instructors. We conclude that both the students and instructors had a very …

The Thayer Method: Student Active Learning With Positive Results, E. Connors

Journal of Mathematics and Science: Collaborative Explorations

Graduation from West Point requires successful completion of four courses in the mathematical sciences. These core mathematics courses include topics in discrete dynamical systems, differential and integral calculus (single variable and multivariable), differential equations, linear algebra, probability, and statistics. The instructional system employed throughout the core is the "Thayer Method," named for Colonel Sylvanus Thayer, "the Father of the Military Academy." In the Thayer Method, traces of cooperative education and "discovery learning" are evident. It is quintessential active learning. The West Point catalyst is the fundamental principle that cadets are responsible for their own education.

Experiences And Thoughts On Stemtec-Inspired Changes In Teaching Physics For Life Science Majors, M. S. Z. Rabin

Journal of Mathematics and Science: Collaborative Explorations

I have taught an introductory course for life science majors three times, each time introducing one or more teaching techniques discussed during the Science, Technology, Engineering, and Mathematics Teaching Education Collaborative (STEMTEC) meetings. Typical class size was 275 students. I cannot make quantitative statements about comparisons between the results of STEMTEC-type teaching methods and traditional teaching methods because I have never taught this course in a completely traditional lecture style. During the first year, I introduced conceptual questions into my lectures. The lecture would be interrupted several times with questions posed to the class. The students then had several minutes …

Steady States Of Dynamically Coupled Two-Species Systems, Muntasi̇r Barma, Sri̇ram Ramaswamy

Turkish Journal of Physics

We study the steady states of two stochastic lattice models with two species of particles, where the local mobility of one species depends on the spatial distribution of the other. The eigenvalues of a $2\times 2$ matrix of couplings can develop imaginary parts, and the question arises whether this implies an instability to a macroscopically different steady state. In the first model, where the mobility depends on the local density of the other species, we show that the system undergoes macroscopic phase separation. In the second model, where the mobility depends on the second derivative of the density of the …

Kinematic Structure Of Minipermeameter Flow, Daniel M. Tartakovsky, J. David Moulton, Vitaly A. Zlotnik

Department of Earth and Atmospheric Sciences: Faculty Publications

Minipermeameters are rapidly becoming a popular tool for collecting localized
measurements of permeability in both laboratory and field studies. While one of the main advantages of minipermeameters is their ability to collect data on various support volumes, there have been only limited attempts to analyze their size and geometry. We define the support volume of minipermeameter measurements as a region containing 90% of the total gas flow, i.e., a region bounded by the 10% streamline. Using our new semianalytical solutions for the Stokes' stream function, we demonstrate that the support volume has a shape of the semitoroid adjacent to the …
