Can Science Methods Really Be Taught On-Line?, W. M. Frazier

Journal of Mathematics and Science: Collaborative Explorations

In this paper, the process in which both project-based curriculum strategies and Blackboard web-based technology were utilized to develop on-line methods courses to prepare science teachers is described. A discussion of the curriculum design process includes a rationale for using project-based instruction in methods courses, along with a rationale for using Blackboard, a web-based technology, as the environment for the course. The course‘s potential for creating highly qualified science teachers as defined by the No Child Left Behind legislation of 2001 and the National Science Teacher Association‘s Standards for Science Teacher Preparation will be explored [1].

History Of A Problem Solving Course For Pre-Service K-8 Teachers, J. Fitzgerald

Journal of Mathematics and Science: Collaborative Explorations

James Madison University's mathematics course in problem solving for prospective K-8 teachers has gone through many changes since we introduced it as a course for prospective middle school teachers four years ago. This paper will discuss the original design of the course, the changes made and their reasons, and the current state of the course.

First Steps Toward Change In Teacher Preparation For Elementary Science, C. Klevickis, R. Kolvoord, M. Handley, K. Giovanetti, D. Peterson, T. Daughtrey, S. Fairchild

Journal of Mathematics and Science: Collaborative Explorations

Unless introductory undergraduate science classes for prospective elementary teachers actively incorporate the philosophy of inquiry-based learning called for in K-l2 science education refom little will change in elementary science education. Thus, at James Madison University, we have developed a new integrated science core curriculum called Understanding our World [1]. This course sequence was not only designed to fulfill general education science requirements. but also to focus on content areas our students will need to know as teachers. The objectives of these courses are based on the National Science Education Standards and Virginia’s Science Standards of Learning, including earth and space …

Hands-On Physical Science For In-Service Teachers, J. Mcdonnough, S. Mckelvey, A. Baski, D. Lewis

Journal of Mathematics and Science: Collaborative Explorations

The initiation of the Virginia Commonwealth University B.S. in Science program was reported in this journal Fall 1999 as a program designed to meet the academic content major of a teacher preparation program for elementary and middle school mathematics and science teachers [1]. This paper reports the current status of the interdisciplinary B.S. in Science degree program including program enrollment data and trends. Also described are refinements in the required curriculum, which include a newly developed geometry, a mathematical computing course, and an emerging teaching technology course featuring graphing calculators, CBLs, and computer software applications.

Helping Provisionally Licensed Middle School Science Teachers, J. J. Matkins, D. R. Sterling, A. Kitsantas

Journal of Mathematics and Science: Collaborative Explorations

The New Science Teachers' Support Network is a National Science Foundation-funded project that provides a multifaceted support system to provisionally licensed middle and high school science teachers.The teachers in this project were all hired to teach science, and had science degrees, but had little or no education coursework or background. Research is being conducted on the effectiveness of the support system we employed for these teachers, particularly on the factors that characterize the practice of new teachers, and on factors that lead to teacher success and teacher retention. In this paper, we describe the design of the study and the …

Aligning Mathematics Curriculum To Create Potential For Active Learning In Pre-K Through Eighth Grade Teacher Education, G. E. Parker

Journal of Mathematics and Science: Collaborative Explorations

In this paper, we consider some issues surrounding the teaching of mathematics to pre-service teachers. In particular. we look at the possibilities for teaching elementary mathematics from an advanced standpoint and alignments of curriculum that have the capacity to enhance student involvement in the making of the mathematics.The particulars of the James Madison University curriculum are used to illustrate many of the points.

Reaching Deep In Math (Developing Educational Excellence And Proficiency In Mathematics), R. D. Anderson

Journal of Mathematics and Science: Collaborative Explorations

This paper describes the DEEP in Math Program developed in the academic year 1998-1999 from a collaborative effort of the Louisiana Systemic lnitiative Program (LaSlP) and the Louisiana Department of Education (LDE). It includes evidence of impressive results in low achieving schools and in high-poverty districts targeted by the effort. The plan was for LaSlP to give intensive content and leadership training in Summer 1999 and academic year 1999-2000 to carefully selected. well-qualified math leaders. These leaders were then employed full-time in the 1999-2000 academic year and beyond by their local education authorities to work with all math teachers in …

Analysis Of Socio-Economic Factors In Correlation To Standardized Educational Test Scores, M. F. Connolly

Journal of Mathematics and Science: Collaborative Explorations

This paper describes the analysis of socio-eeonomic factors in correlation to standardized educational test scores. The scores used were from the Elementary School Proficiency Assessment exam distributed to fourth graders in New Jersey during the years 1999, 200l- 2003 [1-4]. The socio—economie factors are from the 2000 United States Census [5]. Simple regression and other statistical equations were used to compare the data from both sources with Microsoft Excel as a programming tool to perform the analysis.

A Solution To Einstein’S Field Equations For A Tachyonic Gas: Possible Astrophysical Applications, Kris H. Green, W. John Cocke

Mathematical and Computing Sciences Faculty/Staff Publications

In this paper we show that a change in the signs of some of the metric components of the solution of the field equations for the classical cosmic string results in a solution which we interpret as a time-dependent wall composed of tachyons. We show that the walls have the property of focusing the paths of particles which pass through them. As an illustration of this focusing, we demonstrate the results of a simple simulation of the interaction between one such tachyon wall and a rotating disk of point masses. This interaction leads to the temporary formation of spiral structures. …

Physics First, Marcelo Alonso

Aerospace, Physics, and Space Science Faculty Publications

It is true that now most biology courses begin with the DNA molecule, and many chemistry courses introduce the notion of electronic orbitals in atoms and molecules, topics for which students are not well prepared, since most of them have not taken physics courses. Physics courses in turn relegate to the end some discussion of the structure of matter and electromagnetic interaction, or do not discuss that at all. Thus, students miss the overall picture.

Toy Models For The Falling Chimney, Gabriele U. Varieschi, Kaoru Kamiya

Physics Faculty Works

In this paper we review the theory of the ‘‘falling chimney,’’ which deals with the breaking in mid-air of tall structures when they fall to the ground. We show that these ruptures can be caused by either shear forces typically developing near the base, or by the bending of the structure which is caused primarily by the internal bending moment. In the latter case the breaking is more likely to occur between one-third and one-half of the height of the chimney. Small scale toy models are used to reproduce the dynamics of the falling chimney. By examining photos taken during …

Enhancing The Cs Curriculum With With Aspect-Oriented Software Development (Aosd) And Early Experience, Konstantin Läufer, George K. Thiruvathukal, Tzilla Elrad

Computer Science: Faculty Publications and Other Works

Aspect-oriented software development (AOSD) is evolving as an important step beyond existing software development approaches such as object-oriented development. An aspect is a module that captures a crosscutting concern, behavior that cuts across different units of abstraction in a software application; expressed as a module, such behavior can be enabled and disabled transparently and non-invasively, without changing the application code itself. Increasing industry demand for expertise in AOSD gives rise to the pedagogical challenge of covering this methodology and its foundations in the computer science curriculum. We present our curricular initiative to incorporate a novel course in AOSD in the …
