Abstract

This article examines the use of the computer algebra system SAGE for undergraduate student research projects. After reading this article, the reader should understand the benefits of using SAGE as a source of research projects and how to commence working with SAGE. The author proposes a tiered working group model to allow maximum benefit to the students with a reasonable time requirement from the supervising faculty. Once a faculty member is familiar with the current state of SAGE functionality, it is possible to institute a long-term development plan that spans multiple years and students greatly reducing the “setup” time for new students. This model also allows the faculty member to work with a broad range of students as they can support each other. To illustrate this model, outcomes from several years of student research projects are discussed as well as the setup requirements and the process of using SAGE for research. The author worked with five different students over the course of 3 years. This resulted in two refereed undergraduate publications and 41 new additions to the SAGE code base. Of these five students, three entered graduate school, two in mathematics and one in computer science.  相似文献

Abstract

Quantum Information Science (QIS) is an interdisciplinary field involving mathematics, computer science, and physics. Appealing aspects include an abundance of accessible open problems, active interest and support from government and industry, and an energetic, open, and collaborative international research culture. We describe our student–faculty joint work in QIS that has led to many student co-authored papers in research journals. We address program structure and funding, and describe the work performed by our students.  相似文献

BIO2010 advocates enhancing the interdisciplinary, mathematics, and physical science components of the undergraduate biology curriculum. The Department of Chemistry and Life Science at West Point responded by developing a required physical chemistry course tailored to the interests of life science majors. To overcome student resistance to physical chemistry, students were enabled as long-term stakeholders who would shape the syllabus by selecting life science topics of interest to them. The initial 2 yr of assessment indicates that students have a positive view of the course, feel they have succeeded in achieving course outcome goals, and that the course is relevant to their professional future. Instructor assessment of student outcome goal achievement via performance on exams and labs is comparable to that of students in traditional physical chemistry courses. Perhaps more noteworthy, both student and instructor assessment indicate positive trends from year 1 to year 2, presumably due to the student stakeholder effect.  相似文献

Both academic self-concept and interest are considered domain-specific constructs. Previous research has not yet explored how the composition of the courses affects the domain-specificity of these constructs. Using data from a large-scale study in Germany, we compared ninth-grade students who were taught science as an integrated subject with students who were taught biology, chemistry, and physics separately with regard to the dimensional structure of their self-concepts and interests. Whereas the structure of the constructs was six-dimensional in both groups (self-concept and interest factors for biology, chemistry, and physics), the correlations between the domain-specific factors were higher in the integrated group. Furthermore, the pattern of gender differences differed across groups. Whereas male students generally showed higher self-concept and interest in physics and chemistry, a small advantage for male students in biology was only present in integrated science teaching group. We conclude that aspects of the learning environment such as course composition may affect the dimensional structure of motivational constructs.  相似文献

Over the last few years, German federal states have increasingly emphasized and strengthened the subjects regarded as core domains of the Gymnasium (the academic school track), including German, mathematics, foreign languages and, to some extent, science subjects (biology, chemistry, physics) by reducing the number of course and examination options through specific educational reforms. The present study investigates consequences of the reform of upper secondary schooling in the federal state of Saxony on the learning time allocated to subjects and on achievement in the domains of mathematics, English and natural sciences. As expected, the mandatory course selection of science subjects introduced through the reform led to substantially higher achievement levels in physics and chemistry. Moreover, disparities in achievement in the subjects of chemistry and biology were reduced. The reform effects on average achievement levels were strongly associated with course level choices (basic course, advanced course, drop out). Achievement rates relating to course level were, however, largely independent of the amount of allocated learning time. No changes were observed with regard to achievement levels and disparities in mathematics and English.  相似文献

This paper presents a new approach to the Honours Undergraduate Research Course design and implementation. The course design process, assessment and evaluation rubrics are provided. Lessons learned and the experience of the faced challenges and opportunities for two cohort offerings of the course during the winter terms of 2011 and 2012 are highlighted. Assessments show that major benefits include increasing interaction with the faculty and increasing intellectual maturity, skills, knowledge and confidence for the students and for the faculty, the furthering of research projects by the participation of undergraduate students. The course can serve as a model that can be easily adapted for use across the disciplines of science, technology, engineering and mathematics.  相似文献

The BIO2010 report recommended that students in the life sciences receive a more rigorous education in mathematics and physical sciences. The University of Delaware approached this problem by (1) developing a bio-calculus section of a standard calculus course, (2) embedding quantitative activities into existing biology courses, and (3) creating a new interdisciplinary major, quantitative biology, designed for students interested in solving complex biological problems using advanced mathematical approaches. To develop the bio-calculus sections, the Department of Mathematical Sciences revised its three-semester calculus sequence to include differential equations in the first semester and, rather than using examples traditionally drawn from application domains that are most relevant to engineers, drew models and examples heavily from the life sciences. The curriculum of the B.S. degree in Quantitative Biology was designed to provide students with a solid foundation in biology, chemistry, and mathematics, with an emphasis on preparation for research careers in life sciences. Students in the program take core courses from biology, chemistry, and physics, though mathematics, as the cornerstone of all quantitative sciences, is given particular prominence. Seminars and a capstone course stress how the interplay of mathematics and biology can be used to explain complex biological systems. To initiate these academic changes required the identification of barriers and the implementation of solutions.  相似文献

The notion of academic disciplines being characterized as high- or low-paradigm technologies was developed by Lodahl and Gordon from Kuhn's concept of a paradigm. Using this concept, the voting pattern of high-paradigm faculty (chemistry, physics, mathematics, and engineering) was compared to low-paradigm faculty (sociology, political science, history, and education) concerning a controversial campus issue to liberalize curriculum choices for students. It was found that high-paradigm faculty were not willing to grant students more latitude to select courses for degree requirements, while low-paradigm faculty members were in favor of giving students more latitude to select academic courses for degree requirements. The unique aspect of this study is that faculty behavior, as described in an actual case study, corresponds to theoretical positions supported by questionnaire data.  相似文献

A summer program was created for undergraduates and graduate students that teaches bioinformatics concepts, offers skills in professional development, and provides research opportunities in academic and industrial institutions. We estimate that 34 of 38 graduates (89%) are in a career trajectory that will use bioinformatics. Evidence from open-ended research mentor and student survey responses, student exit interview responses, and research mentor exit interview/survey responses identified skills and knowledge from the fields of computer science, biology, and mathematics that are critical for students considering bioinformatics research. Programming knowledge and general computer skills were essential to success on bioinformatics research projects. General mathematics skills obtained through current undergraduate natural sciences programs were adequate for the research projects, although knowledge of probability and statistics should be strengthened. Biology knowledge obtained through the didactic phase of the program and prior undergraduate education was adequate, but advanced or specific knowledge could help students progress on research projects. The curriculum and assessment instruments developed for this program are available for adoption by other bioinformatics programs at http://www.calstatela.edu/SoCalBSI.  相似文献

We describe a unique Research Experience for Undergraduates and Research Experience for Veterinary students summer program at the National Institute for Mathematical and Biological Synthesis on the campus of the University of Tennessee, Knoxville. The program focused on interdisciplinary research at the interface of biology and mathematics. Participants were selected to work on projects with a biology mentor and a mathematics mentor in an environment that promoted collaboration outside of the students'' respective disciplines. There were four research projects with teams of four participants and two faculty mentors. The participants consisted of a mixture of 10 undergraduates in biology- and mathematics-related disciplines, four veterinary students, and two high-school teachers. The activities included lectures on both the biological and mathematical backgrounds of the projects, tutorials for software, and sessions on ethics, graduate school, and possible career paths for individuals interested in biology and mathematics. The program was designed to give students the ability to actively participate in the scientific research process by working on a project, writing up their results in a final report, and presenting their work orally. We report on the results of our evaluation surveys of the participants.  相似文献

Drawing on a number of studies, this paper explores gender differentials in the choice of science subjects at secondary school level, factors influencing choice, differences in achievement and recruitment to science courses at a higher level in the particular educational context of the Maltese Islands. In this context all secondary schools are single‐sex, the state system is highly centralized, selection and streaming are widely practised, a high proportion of students (25%) attend private schools, and physics is compulsory. The results show that: more girls than boys study physics and biology at the lower secondary level (ages 11‐16); more boys study chemistry; achievement at this level is on a par in biology and chemistry; girls achieve slightly lower in physics. At the upper secondary level (ages 16‐18), almost equal numbers of boys and girls study biology and chemistry but boys predominate in physics. Girls avoid the option of physics and mathematics, a popular choice with boys. Consequently, at tertiary level very few girls opt for courses in engineering and prefer to subscribe to courses relating to medicine.  相似文献

Gendered patterns in mathematics and science interest emerge in early childhood, develop over time, and ultimately reflect advanced course selection in secondary education. During the crucial time adolescents become aware of their strengths and interests and specialize accordingly, they get the opportunity to participate in out-of-school learning programs such as mathematics and science competitions. This raises the question whether mathematics and science competitions contribute to gender equity by equally promoting female and male interests. In this article, we present a systematic review on gender differences and the mechanisms explaining success and failure in mathematics and science competitions. On an international level, we found large gender differences regarding participation in all Olympiads with the exception of the biology Olympiad. In fairs and national Olympiads, overall participation rates were not gendered as such, but females preferred biology topics whereas males preferred physics related topics. Male and female achievement in fairs was comparable, but males clearly outperformed female participants at the Olympiads, with the smallest differences in the biology Olympiad. Variables and theoretical frameworks explaining participation and achievement and the role of gender in mathematics and science competitions are discussed. We suggest that gender stereotypes, through their influence on self-concept and interest, play an important role in the mechanisms resulting in low female participation rates in and beyond mathematics and science competitions (especially in physics and chemistry). The mechanisms we found explaining female representation during a national selection competition might be considered as reflecting those in female mathematics or science careers and could thus serve as food for thought on countering the gender gap in mathematics and science.  相似文献

The nature of science (NOS) has a prominent role among the national science education content standards at all grade levels, K–12. Results from a national survey of collegiate science educators indicate the perception that the greatest contributors to preservice teachers’ understanding of the nature of science were science methods courses, research projects, and science content courses. Implications of findings are discussed, including connections to current research concerning teacher preparation for effective NOS classroom teaching and student learning.The Nature of Science course on the authors’ campus was initiated in the early 1990s, has evolved, and remains in the required core curriculum for preservice chemistry, earth science, and physics teacher candidates. It is the capstone for NOS insights. It adds to and refines impressions garnered implicitly from science content courses, the methods course, and, for some, an undergraduate research experience.  相似文献

This article investigates changes in gender differences evident in the performance of grade 8th grade students participating in the Trends in International Mathematics and Science Study (TIMSS) between 1995 and 2003. Gender specific results and patterns found in TIMSS 1995 were compared with later cycles of the study in order to address the question of how far the mathematics and science gender gap has narrowed over time. Using a regression approach to compare the trend data, the findings indicated no major changes for mathematics but it appears that the gap in science may be closing, especially in the previously male dominated content areas of chemistry and physics.  相似文献
