Charles Rueben Keyes And The History Of Iowa Archaeology, William Green

Journal of the Iowa Academy of Science: JIAS

Charles Reuben Keyes (1871-1951) achieved recognition during his lifetime as the "founding father" of Iowa archaeology, and later assessments confirmed and reemphasized Keyes' stature as Iowa's pioneer archaeologist. The collections and documents Keyes compiled, his interpretive publications, and the records of field work he coordinated have proven more valuable to Midwest and Plains archaeology every year. This article emphasizes Keyes' involvement in the development of professionalism in American archaeology and Iowa’s position in the growth of the discipline from 1920 to 1950. Keyes' contacts with the principal archaeologists of his era ensured Iowa’s involvement in the development of survey methods …

Sex-Related Differences In Autonomous Learning Behaviours And Mathematics Achievement, Laura Beahan

Theses : Honours

The autonomous learning behaviour model proposed by Fennema and Peterson (1985a, 1985b) hypothesises that sex- related differences in mathematics are a result of sex-related differences in autonomous learning behaviours. Autonomous learning behaviours include choosing to engage in high-level tasks, preferring to work independently on such tasks and persisting at them. The purpose of this study was to investigate sex-related differences in autonomous learning behaviours and to determine any relationship between the presence of these behaviours and achievement in mathematics. Twelve students studying the Year 1 unit "Foundations of Mathematics" were selected for the study, including two males and two females …

The Meyersville School's Utilization Of Windows On Science, Art D. Anthony

Masters Theses

This study was designed to determine if the students and teachers of Meyersville School, Meyersville, Texas, liked the Windows on Science^® program better than learning and teaching science using the traditional book. All students, grades three through six, and teachers, grades one through six, were surveyed regarding their opinion of Windows on Science^®.

This field experience indicated the students and teachers liked the Windows on Science^® program better than using standard science textbooks. The male students had a higher mean score than the female students or teachers. The teachers felt they needed more experiments to help …

Learning Mathematics As A Language, Kathryn Shafer

Masters Theses

This paper explores the relationship between language and mathematics. It is a summary of research done over the last thirty years. Also included are personal observations which are not part of any controlled study. Since language is the vehicle for thought, mathematics educators and curriculum planners will benefit from a linguistic approach to mathematics education. Symbolic mathematics is similar to natural language in both its structure and its communicative nature. If the students are to internalize the notation, they must be the ones to give it meaning. A linguistic approach to mathematics education includes language development, verbalization of concepts, vocabulary …

Displacement, Velocity, And Frames Of Reference: Phenomenographic Studies Of Students’ Understanding And Some Implications For Teaching And Assessment, John Bowden, Gloria Dall'alba, Elaine Martin, D Laurillard, Ference Marton, Geoff Masters, Paul Ramsden, Andrew Stephanou, E Walsh

Prof Geoff Masters AO

Student understanding of fundamental concepts in kinematics has been explored using the phenomenographic research method. University and high schoolphysics students were interviewed and their understandings of displacement, velocity, and frames of reference have been analyzed in particular problem contexts. Descriptions of the different ways students understand the concepts have been developed and relations between the different levels of understanding have been identified. The data highlight the contextual nature of learning and the need for teachers to focus on the nature of student understanding in specific contexts using questions that require qualitative explanation by students. In particular, it is demonstrated that …
