Approximate Solution Of Abel Integral Equation, Li Huang

Li Huang

This paper presents a new, stable, approximate inversion of Abel integral equation. By using the Taylor expansion of the unknown function, Abel equation is approximately transformed to a system of linear equations for the unknown function together with its derivatives. A desired solution can be determined by solving the resulting system according to Cramer’s rule. This method gives a simple and closed form of approximate Abel inversion, which can be performed by symbolic computation. The nth-order approximation is exact for a polynomial of degree up to n. Abel integral equation is approximately expressed in terms of integrals of input data; …

Moving Beyond Cultural Barriers: Successful Strategies Of Female Technology Education Teachers, Raymond R. Mccarthy, Joseph B. Berger

Joseph B. Berger

Women are underrepresented in Science, Technology, Engineering, and Math fields of study and careers with a subset of STEM--Technology Education--possibly one of the least integrated fields for women as students and as professionals (Akmal, Oaks, & Barker, 2004; Braundy, 2004; Braundy, Petrina, Dalley & Paxton, 2000; Zuga, 1996; Zuga, 1999). What accounts for this situation and what are potential remedies? The purpose of this study was to learn about the ways in which female technology education teachers understand sources of influence on their career choices. The findings from this study are intended to provide insights into the participants; perspectives that …

Introducing New Content Into A School Mathematics Curriculum: The Case Of Cryptology, Kalvin Whittles, Ole-Einar Torkildsen, Cyril Julie, Trygve Breiteig

Kalvin Whittles Dr.

Developing learning resources forms an important part of a school mathematics curriculum implementation. This chapter argues for a change in the way we do analysis for developing learning resources. An argument is forwarded for an undertstanding of the main concepts within the topic as well as a historical and didactical analysis thereof in order to make statements with respect to the teaching and learning of the topic. For this analysis, the topic of cryptology is used as an example. The chapter concludes with recommendations to curriculum designers to revisit the accepted practice to adept already historicalle en didactically analysed materials, …

Developing Problem-Based Curriculum: Unlocking Student Success Utilizing Critical Thinking And Inquiry, William Robertson

William H. Robertson

This book utilizes a Problem-Based Learning (PBL) approach to curriculum development and delivery. PBL is an inquiry-based approach that can be defined as both a curriculum and a process. The curriculum consists of carefully selected and designed problems that engage the learner in the process of acquiring critical knowledge, developing proficiency in problem solving, engaging in self-directed learning, and participating in collaborative teams. Problem-Based Learning (PBL) is a multidisciplinary approach that integrates effective teaching and learning practices with computer technology. This curriculum integration process engages students in collaborative research that can be shared in the classroom, across a community or …

Improving Students’ Algebraic Thinking: The Case Of Talia, Kien H. Lim

Kien H Lim

This paper presents the case of an 11th grader, Talia, who demonstrated improvement in her algebraic thinking after five one-hour sessions of solving problems involving inequalities and equations. She improved from association-based to coordination-based predictions, from impulsive to analytic anticipations, and from inequality-as-a-signal-for-a-procedure to inequality-as-a-comparison-of-functions conceptions. In the one-on-one teaching intervention, she progressed from the sub-context of manipulating symbols, to working with specific numbers, to reasoning with “general” numbers, and eventually to reasoning with symbols. Three features were identified to account for her improvement: (a) attention to meaning, (b) opportunity to repeat similar reasoning, and (c) opportunity to explore.

The Development Of Undergraduate Distance Education Engineering Programs In North Carolina, Sarah A. Rajala, Tom Miller

Sarah A. Rajala

The College of Engineering at North Carolina State University has a strong track record in providing distance education to the citizens in North Carolina through credit-based courses and degree programs. To provide increased access to engineering education on the undergraduate level and enhance the success of the student transfer population, the College of Engineering developed two new 2+2 engineering programs and a distance education bachelor of science in engineering program. The 2+2 programs are designed to provide students enrolled at institutions without engineering programs the opportunity to take some of the fundamental engineering courses in addition to their general education …

Facilitating Identity Formation, Group Membership, And Learning In Science Classrooms: What Can Be Learned From Out Of Field Teaching In An Urban School, Stacy Olitsky

Stacy Olitsky

This paper explores both the obstacles and the possibilities for students developing identities associated with science by engaging in solidarity-building classroom interactions. Data come from ethnographic research conducted in a diverse eighth-grade urban magnet school classroom in which the teacher taught out of field for part of the year. Contrary to expectations, more students participated and reported enjoying science when the teacher was out of field. Analysis of classroom interactions indicated that while in field, the teacher primarily engaged in “front stage” performances that hid her struggles with the material and accentuated students’ views of science as an elite status …

Promoting Student Engagement In Science: Interaction Rituals And The Pursuit Of A Community Of Practice, Stacy Olitsky

Stacy Olitsky

This study explores the relationship between interaction rituals, student engagement with science, and learning environments modeled on communities of practice based on an ethnographic study of an eighth grade urban magnet school classroom. It compares three interactional events in order to examine the classroom conditions and teacher practices that can foster successful interaction rituals (IRs), which are characterized by high levels of emotional energy, feelings of group membership, and sustained interest in the subject. Classroom conditions surrounding the emergence of successful IRs included mutual focus, familiar symbols and activity structures, the permissibility of some side-talk, and opportunities for physical and …

Identity, Interaction Ritual, And Students' Strategic Use Of Science Language, Stacy Olitsky

Stacy Olitsky

An important part of learning science is formulating ideas, debating explanations, and talking about science with others. Yet students may still avoid “talking science” in class even if they are familiar with the content knowledge. Drawing on data from an ethnographic study of an eighth-grade urban science classroom, I argue that students’ expressions of knowledge in science class can be considered a strategic move, or a choice, aimed at supporting identity claims and increasing the likelihood of engaging in successful interaction rituals characterized by entrainment and solidarity. The results of this study suggest that a student’s knowledge of the subject …

A New Abel Inversion By Means Of The Integrals Of An Input Function With Noise, Li Huang

Li Huang

Abel’s integral equations arise inmany areas of natural science and engineering, particularly in plasma diagnostics. This paper proposes a new and effective approximation of the inversion of Abel transform. This algorithm can be simply implemented by symbolic computation, and moreover an nth-order approximation reduces to the exact solution when it is a polynomial in r2 of degree less than or equal to n. Approximate Abel inversion is expressed in terms of integrals of input measurement data; so the suggested approach is stable for experimental data with random noise. An error analysis of the approximation of Abel inversion is given. Finally, …

Learning From People, Things, And Signs, Michael H.G. Hoffmann

Michael H.G. Hoffmann

Starting from the observation that small children can count more objects than numbers—a phenomenon that I am calling the “lifeworld dependency of cognition”—and an analysis of finger calculation, the paper shows how learning can be explained as the development of cognitive systems. Parts of those systems are not only an individual's different forms of knowledge and cognitive abilities, but also other people, things, and signs. The paper argues that cognitive systems are first of all semiotic systems since they are dependent on signs and representations as mediators. The two main questions discussed here are how the external world constrains and …

The Complementarity Of A Representational And An Epistemological Function Of Signs In Scientific Activity, Michael H.G. Hoffmann, Wolff-Michael Roth

Michael H.G. Hoffmann

Signs do not only “represent” something for somebody, as Peirce’s definition goes, but also “mediate” relations between us and our world, including ourselves, as has been elaborated by Vygotsky. We call the first the representational function of a sign and the second the epistemological function since in using signs we make distinctions, specify objects and relations, structure our observations, and organize societal and cognitive activity. The goal of this paper is, on the one hand, to develop a model in which both these functions appear as complementary and, on the other, to show that this complementarity is essential for the …

Increasing Pre-Service Teacher Science Test Success With A Tutorial Cd, William H. Robertson, Brian H. Giza, Stephanie S. Kuehne

William H. Robertson

Pre-service teachers often perform poorly on high-stakes state certification exams. Noting that there were a few particular items and concepts that seemed to be the most problematical, the authors developed a n HTML and flash-based tutorial CD that contained supplementary video and reference materials designed to assist the prospective teacher in preparing for the exam. Research subjects were studied for their preparation for self-regulated learning, as well as language environment, content background, and other factors. Data from scores on the teacher certification exam was correlated with CD use and demographics to identify the effectiveness of the CD tool as an …
