The Relationship Between Middle School Students' Knowledge Of The Concept Of Variable And The Use Of Concrete Manipulatives, Maureen E. Busta

Dissertations and Theses @ UNI

Algebra is a difficult subject for a number of high school students. One of the major concepts involved in the learning of algebra is the use of variables. The purpose of this study was to investigate the effect of the use of concrete manipulatives on middle school students' knowledge of the concept of variable and attitudes toward mathematics.

An experimental study was conducted involving 335 students and 13 teachers. Teachers volunteered to be in the treatment or comparison group. Teachers in the treatment group were trained in the use of Hands-On Equations and used the materials in their classrooms for …

Impact Of Elementary Teachers’ Science Backgrounds On The Teaching Of Science In Iowa Elementary Classrooms, Nancy Lynn Heiter

Dissertations and Theses @ UNI

The purpose of this study was to investigate the high school and college science background of elementary teachers in Iowa and to relate this background to the amount of time these teachers spend teaching about science. The population from which this sample was drawn consisted of elementary school teachers in Iowa. A stratified random sample of schools based on school district size was used. Surveys were mailed to principals, who were asked to distribute the surveys to teachers. From the population surveyed, 475 teachers participated in the study. The chi square analysis was used to show relationships between data collected. …

Student Misconceptions Of Osmosis And Diffusion, Erica J. Mcknight

Theses : Honours

Student misconceptions about two fundamental science concepts, osmosis and diffusion, were elicited using an interview-about-events approach. A concept map and list of 25 propositional statements were used to define the knowledge regarded as important for a sound understanding of the concepts of osmosis and diffusion. The interview probed students’ understandings of the propositions. Eighteen students from a local metropolitan high school were interviewed. These students were selected from four different science classes. Nine students studied Year 12 Biology and nine studied Year 12 Human Biology. Diffusion and osmosis are integral concepts required for thorough understanding of both subjects. The interview-about-events …

Differences In Attitude Towards Mathematics Between Successful Regular Class Children And Children With Learning Problems In Mathematics, Jennifer Poller

Theses : Honours

Possible differences in attitude towards mathematics were studied between Year seven successful regular class children and Year seven children with learning problems in mathematics. A comparison was also made between the Year seven children with learning problems and a younger chronological age group (Year 5) who were performing at approximately the same level in mathematics. A sample of 180 students (30 Year 5 males, 30 Year 5 females, 30 Year 7 regular class males, 30 Year 7 regular class females, 30 Year 7 learning problems males and 30 Year 7 learning problems females) was selected from students in seven local …

Mathematics Anxiety: A Study Of Its Causes As Proclaimed By Educational Research, Jennifer Rupp

Presidential Scholars Theses (1990 – 2006)

In today's fast-paced, high-stress society, feelings of anxiety have become commonplace; even normal. Of the many anxieties that have been found to affect people, one that I, as a future math teacher, have become very concerned about is mathematics anxiety (also called mathphobia). Even now, during my college career, I have noticed an alarming number of people around me (colleagues, co-workers, relatives, roommates, etc.) who claim to be "terrified" of math. Listening to their explanations as to why they find math so threatening has made me realize the importance that math anxiety will have in my career.

For these reasons, …

Advances In Biomolecule Analysis: Ftms Of Macromolecules, Curtiss D. Hanson, Ira M. Simet, Suzanne R. Smith

Journal of the Iowa Academy of Science: JIAS

The development of Fourier transform ion cyclotron resonance (FT-ICR) as an analytical technique has opened new avenues to the analysis of high molecular weight biomolecules. Because mass analysis is based on a detection of a frequency, it is possible to obtain high resolution mass measurements without sacrificing sensitivity. The unique ability to analyze high mass ions is based in the design of a passive ExB ion trap. Although in the past, field inhomogeneities have limited this technique, recent developments in both trap designs and excitation techniques have resulted in major improvements in both sensitivity and resolution.

A Study Of Science Teacher Perceptions And The Implementation Of Science-Technology-Society Education In Iowa Senior High Schools, David L. Johnson

Dissertations and Theses @ UNI

The purpose of this study was to determine the extent to which Science-Technology Society (STS) education has been implemented into the science curriculum and if teachers perceptions and personal assessment of STS education in Iowa senior high schools vary with the teacher's STS background or educational degree. Consisting of 190 senior high school science teachers (grades 9-12) in forty-nine schools distributed throughout the state of Iowa, the sample was obtained by a systematic, stratified sampling of school districts by enrollment size and Area Education Agency districts. Teachers were asked to complete questionnaires designed to collect data concerning: STS background, level …

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 …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Gerald D. Schmidt was born March 12, 1934 in Greeley, Colorado. After finishing his undergraduate degree in Biology at Colorado College in Greeley (now the University of Northern Colorado) Dr. Schmidt went on to receive his masters degree from Colorado State University (CSU) in 1962 and his PhD in 1964 also from CSU. While At CSU he worked under Dr. O. W. Olsen, first on the helminth parasites of the common snipe, and then, for his doctorate, he studied the embryological development of the Acanthocephala. He became a member of the faculty of UNC in Greeley In 1966. His collaboration …

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 …

"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 not …
