The Role of Tribal Elder in Teaching Calculus Through An THE ROLE OF TRIBAL ELDER IN TEACHING CALCULUS THROUGH AN ETHNOMATHEMATICAL LENS A DISSERTATION IN Curriculum and Instruction and Mathematics and Physics Presented to the Faculty of the University of Missouri-Kansas City in partial fulfillment of the requirements for the degree DOCTOR OF PHILOSOPHY by ROBERT RIGGS M.A., University of Missouri-Kansas City, 2003 B.A., University of Missouri-Columbia, 1983 Kansas City, Missouri 2012 © 2012 ROBERT RIGGS ALL RIGHTS RESERVED ROLE OF TRIBAL ELDER IN TEACHING CALCULUS THROUGH AN ETHNOMATHEMATICAL LENS Robert Christensen Riggs, Candidate for the Doctor of Philosophy Degree University of Missouri-Kansas City, 2012 ABSTRACT In action research study I was the classroom teacher of high school-aged African American students participating in the six-week summer portion of the Reach Up program. The purpose of Reach Up is to help students improve study skills, build confidence, motivation, self-discipline, maturity and better grades so that they can go to the college of their choice. Students selected have demonstrated academic promise, are “first-generation” college students, and have been selected from the city’s urban core high schools. This study examined the relational and instructional dynamics that took place in the classroom in which the curriculum was developed through an ethnomathematical lens. Ethnomathematics is grounded in the Freirean model of valuing the intellectual contributions of marginalized cultures and using these contributions to teach for liberation. This study introduces the culturally responsive strategy of teaching as the “Tribal Elder.” A Tribal Elder is one who is a leader in the community, who knows how to navigate the outside world to ensure survival, is related to the students by kin, and is trusted by the students and their parents. How these relations were built, while at the iii same time engaging the students in high-level mathematics is reported. It was hoped that unpacking my teaching and investigating from the inside would lead to further development of the theory of the mathematics teacher as Tribal Elder in the classroom and could then be emulated by others. iv APPROVAL PAGE The faculty listed below, appointed by the Dean of the School of Graduate Studies, have examined a dissertation titled “The Role of the Tribal Elder in Teaching Calculus through an Ethnomathematics Lens,” presented by Robert Riggs, candidate for the Doctor of philosophy degree, and certify that their opinion is worthy of acceptance.

  • 21-110: Problem Solving in Recreational Mathematics Project Assigned Wednesday, March 17, 2010
    21-110: Problem Solving in Recreational Mathematics Project Assigned Wednesday, March 17, 2010. Due Friday, April 30, 2010. This assignment is a group project. You will work in a group of up to four people (i.e., the maximum group size is four). The project is due on Friday, April 30, 2010. Your assignment is to address one of the projects outlined here, and write up your report in a paper. All group members should sign the final report (one report for the whole group). When you sign, you are certifying that you made a fair and honest contribution to the group and that you understand what has been written. I expect to be told of anyone trying to get a free ride. All group members will receive the same grade. You do not necessarily need to address every one of the questions in the project you choose. Conversely, you are welcome to consider additional questions besides the ones listed here. The most important thing is to think critically, creatively, and mathematically about the topic of the project, and to cover it in sufficient depth and detail. Have fun with it! A paper of sufficient length will probably be 8 to 10 pages long (not counting pictures, diagrams, tables, etc.), though longer papers are certainly fine. Note that correct grammar, spelling, readability, and mathematical content all count. Any graphs, diagrams, or other illustrations should be neat, accurate, and appropriately labeled. Start with an introductory paragraph, organize your report in a sensible way, walk your reader through what you are doing, and end with a conclusion.

  • Art and Recreational Math Based on Kite-Tiling Rosettes
    Bridges 2018 Conference Proceedings Art and Recreational Math Based on Kite-Tiling Rosettes Robert W. Fathauer Tessellations Company, Phoenix, AZ 85044, USA; [email protected] Abstract We describe here some properties of kite-tiling rosettes and the wide range of artistic and recreational mathematics uses of kite-tiling rosettes. A kite-tiling rosette is a tiling with a single kite-shaped prototile and a singular point about which the tiling has rotational symmetry. A tiling with n-fold symmetry is comprised of rings of n kites of the same size, with kite size increasing with distance away from the singular point. The prototile can be either convex or concave. Such tilings can be constructed over a wide range of kite shapes for all n > 2, and for concave kites for n = 2. A finite patch of adjacent rings of tiles can serve as a scaffolding for constructing knots and links, with strands lying along tile edges. Such patches serve as convenient templates for attractive graphic designs and Escheresque artworks. In addition, these patches can be used as grids for a variety of puzzles and games and are particularly well suited to pandiagonal magic squares. Three-dimensional structures created by giving the tiles thickness are also explored. Introduction Broadly defined, rosettes are designs or objects that are flowerlike or possess a single point of rotational symmetry. They often contain lines of mirror symmetry through the rotation center as well. Rhombus- based tiling rosettes with n-fold rotational symmetry of the type shown in Fig. 1a are relatively well known and can be constructed for any n greater than 2.

So, I’ll be candid in saying that this is my eighth attempt at writing it. I’ve started and stopped, deleted and retyped, closed my laptop and reopened it. Never in my life have I found it this difficult to write, never in my life has my body physically ached at the thought of sitting down and spending time in my own headspace. Right now, my headspace is the last place on earth I want to be. I’ve decided that this will be my last attempt at writing, and whatever comes out now will remain on the page. I am currently sitting on my couch under a pile of blankets, reclined back as far as my seat will allow me to go. My Amazon Alexa is belting music from an oldies playlist, and my dad is sitting at the kitchen table singing along to “December, 1963” by The Four Seasons as he works.

    Library of Congress [Mistress of Magnolia Hall] Project #-1655 Chalmers S. Murray Edisto Island, S. C. LIFE HISTORY. MISTRESS OF MAGNOLIA HALL. Everything was quiet when I drove up. A few Negroes were moving listlessly about the cotton arbor, and a mangy mouse-colored hound lay like dead on the ground by the whitewashed barn. I took my eyes from the dog lying there in the dust and looked instead at the tall pines, the great laurel tree and the grove of live oaks. Then my eyes refreshed, wandered in a semi-circle and rested on the plantation dwelling - a large two and a half story structure, painted battle ship grey, rising sheerly from the black dirt of the front yard. The breeze died to a whisper. It was too tired even to rustle the pine needles. The September sun was hot on my cheeks, and I walked toward the dwelling already picturing myself seated in one of the porch chairs in the deep shade. Eight black forms were dragging themselves along the path leading to the cotton arbor where the staple would soon be weighed and later put out in the sun to dry. The figures were bearing burlap sacks, stuffed with cotton, on their heads. No words escaped from their thick lips. The last figure in the procession - a copper colored boy of about ten, was followed by a little black dog. I looked closely at the dog as it passed me. It seemed to have purple eyes. The boy walked within a few feet of the spot where the hound was 2 Project #-1655 [Mistress of Magnolia Hall] http://www.loc.gov/resource/wpalh3.31060532 Library of Congress Chalmers S.

  • 1 Joseph Conrad (1857-1924) Youth (1902) This Could Have Occurred
    1 Joseph Conrad (1857-1924) Youth (1902) This could have occurred nowhere but in England, where men and sea interpenetrate, so to speak—the sea entering into the life of most men, and the men knowing something or everything about the sea, in the way of amusement, of travel, or of bread-winning. We were sitting round a mahogany table that reflected the bottle, the claret-glasses, and our faces as we leaned on our elbows. There was a director of companies, an accountant, a lawyer, Marlow, and myself. The director had been a Conway boy, the accountant had served four years at sea, the lawyer—a fine crusted Tory, High Churchman, the best of old fellows, the soul of honor— had been chief officer in the P. & O. service in the good old days when mail- boats were square-rigged at least on two masts, and used to come down the China Sea before a fair monsoon with stun'-sails set alow and aloft. We all began life in the merchant service. Between the five of us there was the strong bond of the sea, and also the fellowship of the craft, which no amount of enthusiasm for yachting, cruising, and so on can give, since one is only the amusement of life and the other is life itself. Marlow (at least I think that is how he spelt his name) told the story, or rather the chronicle, of a voyage: “Yes, I have seen a little of the Eastern seas; but what I remember best is my first voyage there.

  • Popularising Mathematics
    Popularising Mathematics Philipp Legner August 2013 Abstract Mathematics has countless applications in science, engineering and technology, yet school mathematics is one of the most unpopular subjects, perceived as difficult, boring and not useful in life. ‘Popularisation’ projects can help bridge this gap, by showing how exciting, applicable and beautiful mathematics is. Some popularisation projects focus on telling the wider public about mathematics, including its history, philosophy and applications; other projects encourage you to actively do mathematics and discover surprising relationships and beautiful results using mathematical reasoning and thinking. In this report I will develop a framework to classify and evaluate popularisation, and analyse a wide range of existing projects – ranging from competitions to websites, movies, exhibitions, books and workshops. I also reflect upon my personal experiences in designing popularisation activities. I would like to thank Professor Dave Pratt for his advise while writing this report.
