As part of a campus visit on Monday February 24th at 3:30 PM, Rebecca-Anne Dibbs from the University of Northern Colorado will be talking about “The Effects of Formative Assessment on Students’ Zone of Proximal Development in Introductory Calculus”.
Abstract: One of the challenges of teaching introductory calculus is the large variance in student backgrounds. Formative assessment can be used to target which students need help, but little is known about why formative assessment is effective with adult learners. The purpose of this mixed methods study was to investigate which functions of formative assessment that enable instructors to provide the scaffolding needed to engage students in an introductory calculus course within their Zones of Proximal Development during weekly group labs. By regularly collecting information from low-stakes opportunities for students to demonstrate their current understanding, instructors were able to target subsequent class discussion on critical scaffolding for student growth. The formative assessments also enabled students to evaluate their own progress and ask clarifying questions and, provided students who would not ordinarily ask questions during class opportunities for legitimate peripheral participation.

On Monday at 3:30 in Math 357, Kedar Nepal will be talking about “College Algebra Students’ Perceptions on Computer-aided Instruction & An Investigation of Novice College Mathematics Instructors’ Teaching Philosophies”.
Abstract: I will split this talk into two parts. During the first half, I will talk about College Algebra students’ perceptions on a computer-aided college algebra course, a redesigned model from a traditional lecture-based instruction. Students’ beginning-of-semester and end-of-semester responses were analyzed using a constant comparative method of analysis (Strauss & Corbin, 1998). During the second half, I will talk about novice college mathematics instructors’ teaching philosophies, and how their philosophies evolved over time during the pre-service and in-service phases. Three teaching philosophy statements were collected from each participant at different stages of a pre-service program ‘Seminar and Practicum in the Teaching of Collegiate Mathematics’, and three one-on-one interviews were conducted during the in-service phase. Some of the factors that influenced these novice instructors and their teaching philosophies will also be discussed. (flyer in PDF form)
On Thursday February 27th at 3:30, as part of his campus visit Dustin Owen Smith will be talking about “Eliciting Early Elementary School Students’ Informal Inferential Reasoning through Storytelling”.
Abstract:One growing area of research on statistical learning is Informal Inferential Reasoning (IIR). Makar and Rubin (2009) describe IIR as having three components: expressing uncertainty, making and evaluating claims, and drawing explicitly from the data when making or evaluating claims. There is limited research about IIR at the early levels of elementary school but this type of informal reasoning can be a powerful precursor to formal statistical learning in the middle grades (English, 2012). This presentation will discuss a method for providing opportunities for young children (Grades K, 2, and 4) to make informal inferences about data through Storytelling-Questioning. Storytelling-Questioning consists of the researcher reading students a story, and asking strategic questions, that are grounded in the story’s context and content. To understand IIR and the impact of Storytelling-Questioning, this study was built around the following research questions:
- What does Storytelling-Questioning reveal about the similarities and differences in students’ Informal Inferential Reasoning within and across grades K, 2 and 4?
- How can Storytelling-Questioning be leveraged to help early elementary school students engage in Informal Inferential Reasoning?
- What types of questions are most/least effective in engaging students in IIR?
- What types of stories and contexts are most/least effective in engaging students in IIR?
This work has potential to contribute to the description of IIR in the early grades as well as provide a practical pedagogical approach for addressing IIR in the classroom in a way that represents a new way of using storytelling to teach mathematics. Here is a flyer in PDF form
Next Tuesday (note the day change) at 3:30 in Math 357, Dr. Alison Marr from Southwestern University will be speaking about “Magic Directed Graphs.” This talk will be interesting for all levels of students. Abstract: Magic graphs are related to the classic problem of the magic square in which you want to put the numbers 1 to n^2 in an n by n grid such that each row, column, and diagonal adds to the same number. This talk will explore the most up-to-date research in the field of magic directed graphs. We’ll look at definitions and basic examples for a variety of different types of magic labelings. Very little math background is necessary to understand the basic ideas! Many open problems will be given. Flyer in PDF Form
Today at 3:30 in Math 357, Dr. Beverly will be talking about “The Future of Technology in STEM Education.”
Abstract: In this presentation, I will present technology trends for STEM education as well as the challenges to implementation. In addition, we will explore flipped classes, blended classes, and massive classes. These course options are being implemented in universities and colleges across the nation. We will explore what these are and whether they are truly the wave of the future. Flyer in PDF Form
On Monday October 7th at 3:30 in room 357, Dr. David Kahle of Baylor University will be giving our colloquium, “Introducing Algebraic Statistics”.
Abstract: Algebraic statistics is now roughly two decades old, and yet most statisticians don’t really know much about it. One of the barriers to entry is a basic knowledge of the structures, mechanics, and language of algebraic geometry. After laying essential groundwork, in this talk we present an introduction to algebraic statistics by way of one of its earliest mantras: statistical models are algebraic varieties. Along the way, we’ll meet a potpourri of algebraic statistical problems: conditional independence in multiway contingency tables, breakdown of standard asymptotic theory in otherwise nice models, and identifiability in structural equation models.
On Monday, September 23rd at 3:30 in Math 357, Dr. Keith Hubbard and Dr. Mike Stroup will be talking about “Who Should Fund the Government? Exploring Tax Progressivity.”
Abstract: Tax Progressivity is the degree to which those who make higher incomes pay a higher percentage of their income in tax. But total income, total tax, and the distribution of both vary from year to year and from country to country. It can be challenging to determine how progressive a particular situation is. We will look at the mathematics, and the controversy, behind deciding how progressive a particular tax scheme is. (Flyer in PDF Form)
