An Investigation Of The Instructional Norms Of Mathematical Communication When Students Present Geometry Proofs At The Board, Bukola T. Ake

Electronic Theses and Dissertations

Expert mathematical communication is a synthesis of speaking, writing, diagramming, and gesturing. What opportunities are there for secondary mathematics students to learn the discipline-specific ways in which these modalities can be combined to communicate proofs? In an initial effort to investigate this question, Dimmel and Herbst (2020) conducted a multimedia survey experiment to test a hypothesis about how secondary mathematics teachers expect students to communicate when presenting proofs at the board in secondary geometry classrooms. Their hypothesis, based on an analysis of episodes of instruction from a small sample of secondary geometry classrooms, was that teachers expected student presentations of …

Work At The Boundary: A Research-Practice Partnership To Integrate Computer Science Into Middle School Science, Amelia R. Callahan

Electronic Theses and Dissertations

The Maine Center for Research in STEM Education (RiSE Center) is currently developing a partnership between university education researchers, computer science faculty, and middle school science teachers throughout the state. The goal of this partnership is to develop a set of lessons that integrate computer science concepts and practices into existing science curricular materials. This STEM+C partnership brings together individuals who have a wide range of experience and comfort with computer science and teaching middle school. This study focuses on the partnership’s early stages through its initial summer collaborations. We designed and administered interviews prior to the module design process …

Deciphering Climate-Driven Changes In Planktonic Diatom Communities In Lake Superior, Amy Kireta

Electronic Theses and Dissertations

Climate change is affecting lake systems throughout the world, including Lake Superior, the world’s largest lake by surface area. Climate-driven physical changes in Lake Superior are well documented, but there is still substantial uncertainty of how recent biological changes are related to climate change. This research addresses these uncertainties using a variety of approaches to understand the effects of modern climate-driven changes on Lake Superior diatom communities. First, I developed models for environmental variables related to diatom abundance using 10 years of summer monitoring data. Second, I investigated changes in fossilized diatom relative abundances before, during, and after the Medieval …

Discussion In Middle And High School Earth Science Classrooms And Its Impact On Students' Abilities To Construct Evidence-Based Arguments In Their Written Work, Rachel Martin

Electronic Theses and Dissertations

Middle and high school teachers who participate in the Maine Physical Sciences Partnership (MainePSP) noted persistent problems in their classrooms, including low levels of student engagement and gaps in how students use evidence. To address these problems, this study was designed in collaboration with MainePSP teachers in a design-based implementation research process as teachers aimed to better connect classroom discussion and written argumentation. Though scientific writing makes use of argumentation to support ideas, it is often the sharing of ideas that makes an argument stronger.

Two teachers collected data from their seventh and ninth grade Earth Science classrooms at schools …

Increasing Access And Success In The Stem Disciplines: A Model For Supporting The Transition Of High School Students With Disabilities Into Stem-Related Postsecondary Education, Martie Kendrick, Marnie Bragdon-Morneault, Janet May, Alan Kurtz

Transition-Age Resources

This publication (191-page PDF) contains a package of evidenced-based transition supports that can be used by educators or instructors with high school students with disabilities who are interested in pursuing STEM-related postsecondary education and careers. The publication contains information and instructional activities related to the following: self-advocacy and self-determination; exploring STEM careers; disability disclosure; the accommodations process in college; identifying assistive technology; mentoring relationships and internships; and using student- and family-centered planning to prepare for college.

Ideas: Inquiry-Based Dynamic Earth Applications Of Supercomputing, Seeing The Big Picture With Information Technology, Bruce E. Segee, Yifeng Zhu, Peter O. Koons

University of Maine Office of Research Administration: Grant Reports

The goals of the project were to increase the level and volume of information technologies in the classroom and to promote inquiry-based learning. The project was tightly integrated with the Maine Learning Technology Initiative that puts a laptop computer into the hands of every 7th and 8th grade student and teacher. It was also tightly integrated with the University of Maine Supercomputer. Through the use of technology, students were able to ask “what if questions and find and visualize the answers to their questions. The focus of the inquiry was dynamic Earth modelling. This included geological evolution of the earth …
