Restructuring For Mathematical Power: Techniques For Teaching Thinking In Algebra, Barbara D. Nelson Dec 1992

Restructuring For Mathematical Power: Techniques For Teaching Thinking In Algebra, Barbara D. Nelson

Critical and Creative Thinking Capstones Collection

Recent critiques of mathematics education have resulted in proposals to restructure learning and teaching for mathematical power. The new vision pictures the classroom as a community of learners where mathematics come alive as a useful tool in our technological society. However, many high school mathematics teachers are struggling to understand and implement the fundamental instructional change inherent in the vision. Written from the perspective of a high school teacher for experienced high school mathematics teachers, this thesis attempts to bridge vision and practice. To clarify the vision, current literature on reform in mathematics education is synthesized into a framework of ...

"Who Is A Scientist?": Effects Of An Intervention To Change Students' Ideas About Science And Scientists, Lauren A. Foley May 1992

"Who Is A Scientist?": Effects Of An Intervention To Change Students' Ideas About Science And Scientists, Lauren A. Foley

Critical and Creative Thinking Capstones Collection

Advocates for improving science literacy have focused much attention on the negative impressions about science and scientists held by many Americans. The image of scientists as 'nerdy' bespectacled men in laboratories has been related by some researchers to people's lack of interest in pursuing science. This thesis analyzes one component of a program aimed at changing that stereotype. The Science-By-Mail (tm) program at the Museum of Science in Boston was designed to give students a more inclusive image of scientists. Central to the program was the creation of pen-pal relationships between students in grades 4-9 with scientists who did ...


Science Education And The External Perspective On Science, William W. Cobern May 1992

Science Education And The External Perspective On Science, William W. Cobern

Scientific Literacy and Cultural Studies Project

In Kuhnian terms, science education has been a process of inducting students into the reigning paradigms of science. While it may never have been explicit, the goals of science education clearly have been to persuade students that science provides a fairly constant, highly justified, and sufficient understanding of physical phenomena. In 1984, Duschl noted that science education had not kept pace with developments in the history and philosophy of science. Positivism was dethroned years ago and it turns out that factors surrounding discovery are at least as important as the justification of knowledge. Indeed, the entire concept of justification has ...

Computer Science 227X introduces first-year students to programming using Scheme. Computer Science 228X is an introduction to data structures in C++. Both courses attempt to teach principles through extensive practice in programming. This document specifies the course's general objectives and gives an overview of what would be taught.


1991-92 Annual Report, Illinois' Investment, Illinois Mathematics And Science Academy Jan 1992

1991-92 Annual Report, Illinois' Investment, Illinois Mathematics And Science Academy

Annual Reports

On behalf of the board of trustees, faculty, staff, students, parents and alumni of this pioneering educational community, it is our privilege to share with you the sixth annual report of the Illinois Mathematics and Science Academy. The 1991-92 year was indeed a remarkable one for the Academy; we are pleased to report some of the highlights.

Externally, programs for other school systems, teachers and students in Illinois continued to expand. IMSA's impact on the state included helping 23 Illinois school districts restructure their mathematics and science programs, awarding teachers IMPACT II grants to exchange innovative classroom programs, and ...


The Presentation Sequence Of Gas Properties By Physics Textbooks And Science Teachers' Reports, Kevin C. De Berg Jan 1992

The Presentation Sequence Of Gas Properties By Physics Textbooks And Science Teachers' Reports, Kevin C. De Berg

Science and Mathematics Papers and Journal Articles

In this paper, the presentation of the sequence of gas laws is examined to identify cognitive gaps which can hinder student understanding of the concepts involved. Analysis of 14 physics textbooks used in Australian secondary schools and questionnaires from 104 science teachers provided the data for the study. Analysis of the teachers' reports reveals features of the gas law sequence which are inconsistent with the textbook analysis; namely, a low usage of the historical sequence for the gas laws, the use of a sequence which is not necessarily logical, and the use of a simple to complex sequence with no ...


Chaos And Order, Mystery And Knowledge, The Beautiful And Mundane: College Student Conceptualizations Of Nature, William W. Cobern Jan 1992

Chaos And Order, Mystery And Knowledge, The Beautiful And Mundane: College Student Conceptualizations Of Nature, William W. Cobern

Scientific Literacy and Cultural Studies Project

What do students believe about the world around them? Hawkins (1983) suggested that young students can have a difficult time understanding heliocentrism because their personal experience is literally geocentric. What this illustrates is that meaningful learning in the science classroom presupposes students who enter with beliefs about the world compatible with science as it is taught in the classroom. The study of student beliefs (or for that matter, teacher beliefs) at fundamental levels is the study of worldview (Cobern, 1991a). The research reported here was an interpretive study of beliefs about nature, a delimitation of worldview, held by women college ...


Different Perspectives On The Natural World: Biology Professors And Their Students, William W. Cobern Jan 1992

Different Perspectives On The Natural World: Biology Professors And Their Students, William W. Cobern

Scientific Literacy and Cultural Studies Project

The science classroom is the location of complex interactions between students, teacher, curriculum, and environment. These interactions can lead to conflict where the various factors pertaining to students, teacher, curriculum, and environment are at odds. Interest in these types of conflicts has led to numerous studies of classroom processes including those concerned with gender, ethnicity, religion, and language (e.g., Fraser, 1989). Worldview is a factor of more recent interest to researchers and is at an early stage of methodological development and nascent investigation (Cobern, 1991c). Pertaining to the classroom, worldview research focuses on the fundamental beliefs held by teachers ...

2: "The Mapping Of Chromosome 16", Norman A. Doggett, Raymond L. Stallings, Carl E. Hildebrand, Robert K. Moyzis

Genomics: Past & Future

Human chromosome 16 is the main focus of the mapping efforts at Los Alamos. The large photomicrograph on these opening pages illustrates the starting point for those mapping efforts, the evaluation of our chromosome-16-specific library of cloned fragments. Among the 23 pairs of human chromosomes, one pair, chromosome 16, is identified by fluorescence in-situ hybridization. Thousands of yellow fluorescent probes derived from the clone library have hybridized to both copies of chromosome 16. The high density and uniform coverage of the fluorescent signals were a strong indication that we could use the library to construct a map of overlapping cloned ...

Science On The Great Plains: The History Of Physics And Astronomy At The University Of Nebraska-Lincoln, M. Eugene Rudd Jan 1992

Science On The Great Plains: The History Of Physics And Astronomy At The University Of Nebraska-Lincoln, M. Eugene Rudd

M. Eugene Rudd Publications

The year 1988 marked the 100th anniversary of the founding of the Department of Physics at the University of Nebraska. While the year passed without fanfare in the department, DuaneJaecks, one of the members of the faculty, suggested to the author that it would be a good time to write a history of what is now the Department of Physics and Astronomy. He not only provided the initial impetus for the project, but has also given it his continual help and encouragement. While the initial plan was to write only a brief, informal departmental history, the project, like Topsy, grew ...
