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 ...


An Evaluation Of Instructional Grouping And Achievement Within An Accelerated Science Program, John Mark Prouty Jul 1992

An Evaluation Of Instructional Grouping And Achievement Within An Accelerated Science Program, John Mark Prouty

Education and Human Development Master's Theses

This thesis was designed to determine if an accelerated science program had an effect on the performance of accelerates and nonaccelerates on New York State Regents Exams.

Four groups of students representing 54 students were used in the study. Two groups were heterogeneous and two were homogeneous. A t - test analysis was performed to determine if a significant difference in Regents exams existed due to instructional grouping.

Results indicated that this study has shown that no statistically significant difference in scores occurred due to instructional grouping.

"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 ...

Predictors Of Success On The New York State Earth Science Regents Examination, Elaine Matthews Welch Apr 1992

Predictors Of Success On The New York State Earth Science Regents Examination, Elaine Matthews Welch

Education and Human Development Master's Theses

The 1970 New York State Earth Science Regents Syllabus targeted students who displayed a high degree of ability and interest in science. The State Education Department has been reluctant to define exactly what constitutes a higher ability and interest. However it has often been suggested to represent the top 10 to 25% of any given class. This can lead parents and teachers to wonder if there is a factor that can predict a student’s performance. This master thesis examines a number of variables to determine if any of them can be used to help predict the probability of success ...

Gender Differences In Mathematics Achievement And Confidence In The Learning Of Mathematics In Grades Eight And Nine Of A Montana Community, Darcie Hilton Apr 1992

Gender Differences In Mathematics Achievement And Confidence In The Learning Of Mathematics In Grades Eight And Nine Of A Montana Community, Darcie Hilton

Mathematics, Engineering and Computer Science Undergraduate Theses

This thesis reviews past research on gender differences in mathematics achievement and attitudes toward mathematics. The review is divided into three categories: gender differences that have been found in mathematics, possible causes of those gender differences, and ways to eliminate the gender differences. A small community in Montana was tested for gender differences in mathematics achievement and confidence in the learning of mathematics. The subjects consisted of 55 females and 56 males in grades eight and nine. The subjects’ scores on the Fennema-Sherman Confidence in the Learning of Mathematics Scale and the CTBS Mathematics Achievement Test were compared to each ...

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 ...

Fifty Years Of Fisheries Management M An Obstinate Prairie Lake, Dennis L. Scarnecchia, James R. Wahl Jan 1992

Fifty Years Of Fisheries Management M An Obstinate Prairie Lake, Dennis L. Scarnecchia, James R. Wahl

Journal of the Iowa Academy of Science: JIAS

Little Wall Lake, a shallow 104 ha glacial lake in Hamilton County, Iowa, has been manipulated for about 50 years by fishery managers in an attempt to provide a stable sport fishery. Managers have used dredging, water level manipulation, aquatic vegetation control, mechanical fish removal and fish eradication with toxicants, sport fish stocking, introduction of piscivorous fish, artificial habitat structures, and winter aeration. Attempts to stabilize the fishery have been unsuccessful, and because of overpopulation and stunting of panfishes, total fish eradications were conducted in 1977 and 1989. We review the history of management efforts on the lake, and suggest ...

Geology Of Iowa Fens, C. A. Thompson, E. A. Bettis Iii, R. G. Baker Jan 1992

Geology Of Iowa Fens, C. A. Thompson, E. A. Bettis Iii, R. G. Baker

Journal of the Iowa Academy of Science: JIAS

Fens are peatlands which are dependent on groundwater discharge to provide nutrient enrichment. Fens are found in a variety of landscape positions and in most Iowa landform regions. This paper presents a classification system for Iowa fens based on landscape position, stratigraphy, and hydrologic factors. Iowa fens can be separated into six categories: 1) fens along valley wall slopes; the groundwater source for these fens is sand and gravel buried between glacial tills (inter-till); 2) fens in hummocky topography on the northwestern margin of the Des Moines Lobe landform region; the water source is sand and gravel buried within glacial ...


The Specific Surface Area Values For Iowa Tills, Keith E. Schilling, Brian L. Gedlinske Jan 1992

The Specific Surface Area Values For Iowa Tills, Keith E. Schilling, Brian L. Gedlinske

Journal of the Iowa Academy of Science: JIAS

Specific surface area is a property used by earth scientists to estimate the proportion of expandable clay minerals in soils. In this study, specific surface area method is shown to compare favorably with standard clay mineralogical techniques in determining gross differences in expandable clay mineral content in tills. The results of over 100 measurements on till samples from Iowa indicate undifferentiated pre-Illinoian tills from southern and southwestern Iowa have the highest specific surface area values of Iowa tills (ranging from nearly 100 to greater than 150 m2/g) and Wisconsinan Dows Formation tills have the lowest average specific surface ...

Three Botanists: Bessey, Pammel, And Hayden, Duane Isely, Lois Tiffany Jan 1992

Three Botanists: Bessey, Pammel, And Hayden, Duane Isely, Lois Tiffany

Journal of the Iowa Academy of Science: JIAS

Bessey was a multidirectioned innovator and evangelist of botanical education, conservation, and scientific agriculture. For example, he initiated the first undergraduate laboratory using microscopes for botany instruciton and he had no peer as a botany teacher in the latter part of the 19th century. His enthusiasm about the natural history of Iowa and surrounding states broadened the horizons of innumerable students and he was one of the founders of the Iowa Academy of Science. An organization man, Bessey quickly became president of any group with which he became affiliated, and eventually was both nationally and internationally known through his text ...

The University Of Iowa Museum Of Natural History: An Historical Perspective, George D. Shrimper Jan 1992

The University Of Iowa Museum Of Natural History: An Historical Perspective, George D. Shrimper

Journal of the Iowa Academy of Science: JIAS

The 132-year record of UIMNH essentially mirrors historical and on-going trends in related institutions. As scholarship grew in the natural sciences during the 19th century, natural history museums became centers for scientific research. A "Golden Age" of museum-based expeditionary work and taxonomic research was marked at UI by the careers of curator/naturalists Calvin, Nutting, Macbride, and Shimek. Systematic biology and paleontology thrived with the accumulation of extensive collections. De-emphasis of "natural history" studies followed after 1920-30 with a concomitant growth in cellular and molecular biology. In seeking new directions and financial support, many museums, including UIMNH, shifted emphasis to ...
