Building Student Self-Assessment Tools

In this workshop we will discuss possible ways to encourage students to self assess their understanding of mathematical concepts. The goal is to make progress on building student assessment tools that will help them take ownership of their learning of the course content as well as help them prepare for exams.

CSI at ISU: Math, stats and computer science applications to solve forensic science questions

**Speakers** *AC*
## Alicia Carriquiry

CSAFE is a federally funded center with a mission to develop statistical and computational methods to address forensic questions. The focus is on pattern evidence (fingerprints, shoeprints, firearms, handwriting and blood spatter) and digital evidence. Evaluating this type of evidence is challenging, because it typically involves quantifying the similarity between images, and the standard statistical methods fall short. We rely on learning algorithms and computational methods and produce solutions that both scientifically solid and practical. We work on interesting problems and would like to collaborate with Iowa teachers in the development of educational materials. The goal is to provide teachers with an opportunity to broaden their knowledge in data science, statistics and computational methods and to encourage their students to pursue careers in STEM, including forensic science.

Contextualized Instruction as Motivational Intervention in Calculus

Calculus students often ask: why are we learning this? If students are not given the opportunity to see this connection, they might become disengaged (Harackiewicz, Tibbetts, Canning, & Hyde, 2014). The aim of this study is to examine the impact of an interdisciplinary approach to student motivational aspects: utility-value, interest, and performance expectations. A quasi-experimental research design was employed to investigate these motivational aspects. Participants were enrolled in an introductory calculus course and approximately 81 of them (from six sections) were involved. The intervention was comprised of three calculus tasks with applications to science, technology, and engineering disciplines. The results will be discussed in terms of multiple statistical analysis techniques.

Exploring Concepts through Authentic Data Models

**Speakers**

Learn how authentic data collection and analysis allows us to engage students with the Standards for Mathematical Practice, especially “Model with Mathematics” and “Construct viable arguments and critique the reasoning of others”. Wading through messy data allows students to process and make sense of mathematical concepts and tools we need them to learn through interesting contexts. We’ll share activities used from our Algebra II, AP Statistics and Calculus classes, and share how can you incorporate data collection and analysis to your lessons to increase student engagement and understanding.

Triangle Congruence Theorems: Developing Reasoning Through Informal Arguments

**Speakers**
## Brooke Krejci

This session will include the description of an activity used to introduce triangle congruence theorems in a high school geometry course. The purpose of this activity is to develop students’ reasoning and justification through informal arguments prior to writing proofs using triangle congruence theorems. Participants will discuss the number of elements needed to prove two triangles congruent. Participants will then be assigned a possible triangle congruence theorem. Group discussion will follow, including arguments formulated by participants, as well as student examples from high school geometry students. The session will conclude with a summary of the activity and its use for implementation in a high school geometry course.

Using Technology to Develop Discourse in the High School Math Classroom

**Speakers**
## Michael Fenton

Imagine a classroom full of students and devices. What does it sound like? Too often, the introduction of technology into a high school math classroom brings with it silence. How can we leverage technology to create more social and creative classrooms? How can we use technology to include rather than isolate? Bring a device, bring your experience, and bring your voice as we explore these ideas together.

Introduction to the Desmos Graphing Calculator

In this session participants will learn about the free Desmos online graphing calculator. The presenter will share how the Desmos calculators can be used for both teacher modeling and student problem-solving. Use movable points, dynamic sliders, quick regression, geometry constructions, and more to help your students make sense of math. Bring a tablet or laptop to maximize your participation.
