Investigating How Students Communicate Tree-Thinking, Carrie Jo Boyce

Dissertations

Learning is often an active endeavor that requires students work at building conceptual understandings of complex topics. Personal experiences, ideas, and communication all play large roles in developing knowledge of and understanding complex topics. Sometimes these experiences can promote formation of scientifically inaccurate or incomplete ideas. Representations are tools used to help individuals understand complex topics. In biology, one way that educators help people understand evolutionary histories of organisms is by using representations called phylogenetic trees. In order to understand phylogenetics trees, individuals need to understand the conventions associated with phylogenies.

Reflections On Math Students’ Circles: Two Personal Stories From Colorado, Diana White, Lori Ziegelmeier

Journal of Humanistic Mathematics

Math Students’ Circles provide an opportunity for mathematicians to work in their communities to engage young students in mathematics as a human, aesthetic, and social endeavor. Sometimes referred to simply as Math Circles, these venues give mathematicians experience in introducing children to topics not typically seen in school curricula in an exciting, hands-on format. This article explores two Math Students’ Circles (MSCs) in the state of Colorado from the point of view of two pre-tenure faculty members. One participated in MSCs for four years while working on her Ph.D. in mathematics, the other started an MSC as an offshoot of …

On Similarities And Differences Between Proving And Problem Solving, Milos Savic

Journal of Humanistic Mathematics

A link between proving and problem solving has been established in the literature [5, 21]. In this paper, I discuss similarities and differences between proving and problem solving using the Multidimensional Problem-Solving Framework created by Carlson and Bloom [2] with Livescribepen data from a previous study [13]. I focus on two participants’ proving processes: Dr. G, a topologist, and L, a mathematics graduate student. Many similarities between the framework and the proving processes of Dr. G and L were revealed, but there were also some differences. In addition, there were some distinct differences between the proving actions of the …

Attitudes And Experiences In Liberal Arts Mathematics, Jennifer Clinkenbeard

Journal of Humanistic Mathematics

For many university students, the last formal experience in a mathematics classroom is a single semester “general education” mathematics class. Traditionally, students in this type of class often hold negative attitudes towards mathematics. Here I study a sample of students from this population (49 students at a large, urban, comprehensive public university enrolled in a “math for liberal arts majors” course) to research whether a positive experience in a freshman-level general education mathematics course correlates with a positive change in the students’ attitude towards mathematics in general. I also explore which specific aspects of such a course contribute most to …

E-Brock Bugs©: An Epistemic Mathematics Computer Game, Laura Broley, Chantal Buteau, Eric Muller

Journal of Humanistic Mathematics

Devlin in [7] argues that video games are an ideal medium for the teaching and learning of mathematics, though he points out that very few ’good’ mathematics video games exist. Building on a probabilistic board game developed in the 1980s, we created a mathematics computer game, E-Brock Bugs. The design of the game carefully follows Devlin’s principles of a good mathematics video game, including a well-developed storyline, the selection of an in-game avatar, and an environment where mathematics arises in a natural and meaningful way. As a result, we argue that E-Brock Bugs is an epistemic computer game [1]; …

Ninth Grade Student Responses To Authentic Science Instruction, Michael Steven Ellison

Dissertations and Theses

This mixed methods case study documents an effort to implement authentic science and engineering instruction in one teacher's ninth grade science classrooms in a science-focused public school. The research framework and methodology is a derivative of work developed and reported by Newmann and others (Newmann & Associates, 1996). Based on a working definition of authenticity, data were collected for eight months on the authenticity in the experienced teacher's pedagogy and in student performance. Authenticity was defined as the degree to which a classroom lesson, an assessment task, or an example of student performance demonstrates construction of knowledge through use of …

Promoting Numeracy In An Online College Algebra Course Through Projects And Discussions, Samuel L. Tunstall, Michael J. Bossé

Numeracy

This research stems from efforts to infuse quantitative literacy (QL) in an online version of college algebra. College algebra fulfills a QL requirement at many universities, and it is a terminal course for most who take it. In light of the course’s traditional content and teaching methods, students often leave with little gained in QL. An online platform provides a unique means of engaging students in quantitative discussions and research, yet little research exists on online courses in the context of QL. The course studied included weekly news discussions as well as “messy” projects requiring data analysis. Students in online …

Implementing Quantitative Literacy At Southwestern Community College, North Carolina, Vicki Todd, John Wagaman

Numeracy

There is a time when articulation agreements between universities and community colleges come to an end. When this happened in North Carolina, there was great hope that not only would the mathematics classes that were offered in the North Carolina Community College System be revamped with respect to overlapping content, but also that mathematics classes would be developed that have a clear connection between what is seen in the world and what is taught in the classroom especially for non-STEM (science, technology, engineering, and mathematics-related studies) students. This paper describes how Southwestern Community College (SCC) implemented a quantitative literacy class …

Task-based instruction has been a promising method of instruction advocated by mathematics education researchers over the past twenty years. However traditional curricula constitute a majority of the curricula utilized in the United States. The purpose of this study is to identify the problems reform oriented novice teachers face when utilizing a traditional curriculum to plan task-based lessons. In order to identify these problems three novice teachers' interactions with curricula were observed and characterized using the frameworks of past researchers. Through analysis of teachers' textbook interaction practices it was found that teachers struggled to plan task-based lessons due to issues encountered …

The Impact Of Design-Based Modeling Instruction On Seventh Graders' Spatial Abilities And Model-Based Argumentation, William J. Mcconnell

Teaching & Learning Theses & Dissertations

Due to the call of current science education reform for the integration of engineering practices within science classrooms, design-based instruction is receiving much attention in science education literature. Although some aspect of modeling is often included in well-known design-based instructional methods, it is not always a primary focus. The purpose of this study was to better understand how design-based instruction with an emphasis on scientific modeling might impact students' spatial abilities and their model-based argumentation abilities. In the following mixed-method multiple case study, seven seventh grade students attending a secular private school in the Mid-Atlantic region of the United States …
